STATEMENT ON FORWARD LOOKING INFORMATION

Certain information presented in this report may contain “forward-looking statements” within the meaning of the federal securities laws including the Private Securities Litigation Reform Act of 1995. Forward looking statements include statements concerning our plans, objectives, goals, strategies, future events, future revenues or performance, capital expenditures, financing needs, plans or intentions relating to acquisitions and other information that is not historical information. In some cases, forward looking statements can be identified by terminology such as “believes,” “plans,” “intends,” “expects,” “estimates,” “may,” “will,” “should,” or “anticipates” or the negative of such terms or other comparable terminology, or by discussions of strategy. All forward-looking statements made by the Company involve known and unknown risks, uncertainties and other factors, many of which are beyond the control of the Company, which may cause the Company’s actual results to be materially different from those expressed or implied by such statements. We may also make additional forward looking statements from time to time. All such subsequent forward-looking statements, whether written or oral, by us or on our behalf, are also expressly qualified by these cautionary statements. All forward-looking statements, including without limitation, management’s examination of historical operating trends and estimates of future earnings, are based upon our current expectations and various assumptions. Our expectations, beliefs and projections are expressed in good faith and we believe there is a reasonable basis for them, but there can be no assurance that management’s expectations, beliefs and projections will result or be achieved.

All forward looking statements apply only as of the date made. Except as required by law, we undertake no obligation to publicly update or revise forward looking statements which may be made to reflect events or circumstances after the date made or to reflect the occurrence of unanticipated events.

There are a number of risks and uncertainties that could cause our actual results to differ materially from the forward-looking statements contained in or contemplated by this report. Any forward-looking statements should be considered in light of the risks referenced in “Item 1A. Risk Factors” included in our most recent annual report on Form 10-K and in other subsequent filings with the Securities and Exchange Commission (the “SEC”). Such factors include, but are not limited to:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

CAUTIONARY LANGUAGE

The following discussion and analysis should be read in conjunction with our unaudited “Condensed Consolidated Financial Statements” and the “Notes to Consolidated Financial Statements (unaudited)” appearing elsewhere in this report. We make statements in this section that may be forward looking statements within the meaning of the federal securities laws. For a complete discussion of forward looking statements, see the section in this report entitled “Statement on Forward Looking Information.” References to the “Company,” “we,” “us,” or “our company” refer to Global Self Storage, Inc., a Maryland corporation, including, as the context requires, its direct and indirect subsidiaries.

CRITICAL ACCOUNTING POLICIES

Our discussion and analysis of our financial condition and results of operations are based on our unaudited condensed consolidated financial statements contained elsewhere in this report, which have been prepared in accordance with GAAP. Our notes to the unaudited condensed consolidated financial statements contained elsewhere in this report describe the significant accounting policies essential to our unaudited condensed consolidated financial statements. Preparation of our financial statements requires estimates, judgments, and assumptions. We believe that the estimates, judgments, and assumptions that we have used are appropriate and correct based on information available at the time they were made. These estimates, judgments, and assumptions can affect our reported assets and liabilities as of the date of the financial statements, as well as the reported revenues and expenses during the period presented. If there are material differences between these estimates, judgments, and assumptions and actual facts, our financial statements may be affected.

In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP and does not require our judgment in its application. There are areas in which our judgment in selecting among available alternatives would not produce a materially different result, but there are some areas in which our judgment in selecting among available alternatives would produce a materially different result. Please refer to the notes to the unaudited condensed consolidated financial statements that contain additional information regarding our critical accounting policies and other disclosures.

Management’s Discussion and Analysis Overview

The Company is a self-administered and self-managed REIT that owns, operates, manages, acquires, and redevelops self storage properties (“stores” or “properties”) in the United States. Our stores are designed to offer affordable, easily accessible, and secure storage space for residential and commercial customers. As of September 30, 2024, the Company owned and operated, or managed, through its wholly owned subsidiaries, thirteen stores located in Connecticut, Illinois, Indiana, New York, Ohio, Pennsylvania, South Carolina, and Oklahoma. The Company was formerly registered under the Investment Company Act of 1940, as amended (the “1940 Act”) as a non-diversified, closed end management investment company. The Securities and Exchange Commission’s (“SEC”) order approving the Company’s application to deregister from the 1940 Act was granted on January 19, 2016. On January 19, 2016, the Company changed its name to Global Self Storage, Inc. from Self Storage Group, Inc., changed its SEC registration from an investment company to an operating company reporting under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and listed its common stock on NASDAQ under the symbol “SELF”.

The Company was incorporated on December 12, 1996 under the laws of the state of Maryland. The Company has elected to be treated as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). To the extent the Company continues to qualify as a REIT, it will not generally be subject to U.S. federal income tax, with certain limited exceptions, on its taxable income that is distributed to its stockholders.

Our store operations generated most of our net income for all periods presented herein. Accordingly, a significant portion of management’s time is devoted to seeking to maximize cash flows from our existing stores, as well as seeking investments in additional stores. The Company expects to continue to earn a majority of its gross income from its store operations as its current store operations continue to develop and as it makes additional store acquisitions. Over time, the Company expects to divest its remaining portfolio of investment securities and use the proceeds to acquire and operate additional stores. The Company expects its income from investment securities to continue to decrease as it continues to divest its holdings of investment securities.

Financial Condition and Results of Operations

 

Our financing strategy is to minimize the cost of our capital in order to maximize the returns generated for our stockholders. For future acquisitions, the Company may employ various financing and capital raising alternatives including, but not limited to, debt and/or equity offerings, credit facilities, mortgage financing, and joint ventures with third parties.

On June 24, 2016, certain wholly owned subsidiaries of the Company (“Term Loan Secured Subsidiaries”) entered into a loan agreement and certain other related agreements (collectively, the “Term Loan Agreement”) between the Term Loan Secured Subsidiaries and Insurance Strategy Funding IV, LLC (the “Term Loan Lender”). Under the Term Loan Agreement, the Term Loan Secured Subsidiaries borrowed from Term Loan Lender in the principal amount of $20 million pursuant to a promissory note (the “Term Loan Promissory Note”). The Term Loan Promissory Note bears an interest rate equal to 4.192% per annum and is due to mature on July 1, 2036. Pursuant to a security agreement (the “Term Loan Security Agreement”), the obligations under the Term Loan Agreement are secured by certain real estate assets owned by the Term Loan Secured Subsidiaries. J.P. Morgan Investment Management, Inc. acted as Special Purpose Vehicle Agent of the Term Loan Lender. The Company entered into a non-recourse guaranty (the “Term Loan Guaranty,” and together with the Term Loan Agreement, the Term Loan Promissory Note and the Term Loan Security Agreement, the “Term Loan Documents”) to guarantee the payment to the Term Loan Lender of certain obligations of the Term Loan Secured Subsidiaries under the Term Loan Agreement. We have used some of the proceeds from the Term Loan Agreement to acquire four self storage properties in 2016.

 

On December 20, 2018, certain of our wholly owned subsidiaries (“Credit Facility Secured Subsidiaries”) entered into a revolving credit loan agreement (collectively, the “Credit Facility Loan Agreement”) between the Credit Facility Secured Subsidiaries and TCF National Bank (“Credit Facility Lender”). Under the Credit Facility Loan Agreement, the Credit Facility Secured Subsidiaries may borrow from the Credit Facility Lender in the principal amount of up to $10 million pursuant to a promissory note (the “Credit Facility Promissory Note”). The Credit Facility Promissory Note bears an interest rate equal to 3.00% over the One Month U.S. Dollar London Inter-Bank Offered Rate and was due to mature on December 20, 2021. The obligations under the Credit Facility Loan Agreement are secured by certain real estate assets owned by the Credit Facility Secured Subsidiaries. We entered into a guaranty of payment on December 20, 2018 (the “Credit Facility Guaranty,” and together with the Credit Facility Loan Agreement, the Credit Facility Promissory Note and related instruments, the “Credit Facility Loan Documents”) to guarantee the payment to the Credit Facility Lender of certain obligations of the Credit Facility Secured Subsidiaries under the Credit Facility Loan Agreement. As described in more detail below, the Credit Facility Loan Agreement has been replaced in its entirety by the Amended Credit Facility Loan Agreement on July 6, 2021.

 

On December 18, 2019, we completed a rights offering whereby we sold and issued an aggregate of 1,601,291 shares of our common stock (“common stock”) at the subscription price of $4.18 per whole share of common stock, pursuant to the exercise of subscriptions and oversubscriptions from our stockholders. We raised aggregate gross proceeds of approximately $6.7 million in the rights offering.

 

On May 19, 2020, an affiliate of the Company (the “Borrower”) entered into a Paycheck Protection Program Term Note (“PPP Note”) with Customers Bank on behalf of itself, the Company, and certain other affiliates under the Paycheck Protection Program of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) administered by the U.S. Small Business Administration (the “SBA”). The Borrower received total proceeds of $486,602 from the PPP Note. On April 5, 2022, the Borrower was granted forgiveness of the entire PPP Note and any accrued interest. Upon forgiveness, the Company received $307,210 in cash from the Borrower, which was the amount attributable to the Company under the SBA's loan determination formula, and recorded a gain for such amount in its consolidated statements of operations and comprehensive income.

 

On June 25, 2021, we completed an underwritten public offering whereby we sold and issued an aggregate of 1,121,496 shares of our common stock at the price of $5.35 per share. Subsequently, the over-allotment option was exercised, increasing the total number of shares sold and issued to 1,289,720. We raised aggregate gross proceeds of approximately $6.9 million in the public offering after giving effect to the exercise of the over-allotment option.

On July 6, 2021, certain wholly owned subsidiaries (“Amended Credit Facility Secured Subsidiaries”) of the Company entered into a first amendment to the Credit Facility Loan Agreement (collectively, the “Amended Credit Facility Loan Agreement”) between the Amended Credit Facility Secured Subsidiaries and The Huntington National Bank, successor by merger to TCF National Bank (“Amended Credit Facility Lender”). Under the Amended Credit Facility Loan Agreement, the Amended Credit Facility Secured Subsidiaries were able to borrow from the Amended Credit Facility Lender in the principal amount of up to $15 million, reduced to $14.75 million and $14.5 million in years 2 and 3, respectively, pursuant to a promissory note (the “Amended Credit Facility Promissory Note”). The Amended Credit Facility Promissory Note bore an interest rate equal to 3% plus the greater of the One Month U.S. Dollar London Inter-Bank Offered Rate or 0.25% and was due to mature on July 6, 2024. As of September 30, 2024, the effective interest rate was 8.44%. The publication of LIBOR ceased after June 30, 2023. The Amended Credit Facility Loan Agreement provided for a replacement index based on the Secured Overnight Financing Rate (“SOFR”). The interest rate on the Amended Credit Facility Promissory Note subsequent to June 30, 2023, was equal to 3% plus the greater of SOFR plus 0.11448% or 0.25%. The obligations under the Amended Credit Facility Loan Agreement were secured by certain real estate assets owned by the Amended Credit Facility Secured Subsidiaries. The Company entered into an amended and restated guaranty of payment on July 6, 2021 (“Amended Credit Facility Guaranty,” and together with the Amended Credit Facility Loan Agreement, the Amended Credit Facility Promissory Note and related instruments, the “Amended Credit Facility Loan Documents”) to guarantee the payment to the Amended Credit Facility Lender

of certain obligations of the Amended Credit Facility Secured Subsidiaries under the Amended Credit Facility Loan Agreement. The Company and the Amended Credit Facility Secured Subsidiaries paid customary fees and expenses in connection with their entry into the Amended Credit Facility Loan Documents. As described in more detail below, the Amended Credit Facility Loan Agreement has been replaced in its entirety by the Second Amended Credit Facility Loan Agreement on July 6, 2024.

On January 14, 2022, the Company entered into an At Market Offering Sales Agreement (the “Sales Agreement”) with B. Riley Securities, Inc. (the “Agent”) pursuant to which the Company may sell, from time to time, shares of common stock having an aggregate offering price of up to $15,000,000, through the Agent. During the twelve months ended December 31, 2022, under the Sales Agreement, the Company sold and issued an aggregate of 373,833 shares of common stock and raised aggregate gross proceeds of approximately $2,272,628, less sales commissions of approximately $45,491 and other offering costs resulting in net proceeds of $2,008,436. There were no shares of common stock sold during the three and nine months ended September 30, 2024 and September 30, 2023 under the Sales Agreement.

On July 6, 2024, certain wholly owned subsidiaries (“Second Amended Credit Facility Secured Subsidiaries”) of the Company entered into a second amendment to the Credit Facility Loan Agreement (collectively, the “Second Amended Credit Facility Loan Agreement”) between the Second Amended Credit Facility Secured Subsidiaries and The Huntington National Bank, successor by merger to TCF National Bank (“Second Amended Credit Facility Lender”). Under the Second Amended Credit Facility Loan Agreement, the Second Amended Credit Facility Secured Subsidiaries may borrow from the Second Amended Credit Facility Lender in the principal amount of up to $15 million, reduced to $14.75 million and $14.5 million in years 2 and 3, respectively, pursuant to a promissory note (the “Second Amended Credit Facility Promissory Note”). The Second Amended Credit Facility Promissory Note bears an interest rate equal to 3% plus the greater of the One Month SOFR or 0.25% and is due to mature on July 6, 2027, with an option to extend the maturity to July 6, 2028. An annual unused facility fee is charged based on the daily average of the unadvanced amount of the Second Amended Credit Facility Loan Agreement during the trailing twelve month period ending each June 30. The fee will be calculated at 0.25% per annum if the daily average of the unadvanced amount of the Second Amended Credit Facility Loan Agreement during such trailing twelve month period was greater than fifty percent, and will be calculated at 0.15% if the daily average of the unadvanced amount of the Second Amended Credit Facility Loan Agreement during such trailing twelve month period was less than or equal to fifty percent. The obligations under the Second Amended Credit Facility Loan Agreement are secured by certain real estate assets owned by the Second Amended Credit Facility Secured Subsidiaries. The Company entered into a second amended and restated guaranty of payment as of July 6, 2024 (“Second Amended Credit Facility Guaranty,” and together with the Second Amended Credit Facility Loan Agreement, the Second Amended Credit Facility Promissory Note and related instruments, the “Second Amended Credit Facility Loan Documents”) to guarantee the payment to the Second Amended Credit Facility Lender of certain obligations of the Second Amended Credit Facility Secured Subsidiaries under the Second Amended Credit Facility Loan Agreement. The Company and the Second Amended Credit Facility Secured Subsidiaries paid customary fees and expenses in connection with their entry into the Second Amended Credit Facility Loan Documents. The Company also maintains a bank account at the Second Amended Credit Facility Lender. As of September 30, 2024, we have no withdrawn proceeds under the Second Amended Credit Facility Loan Agreement. We currently intend to strategically withdraw proceeds available under the Second Amended Credit Facility Loan Agreement to fund: (i) the acquisition of additional self storage properties, (ii) expansions at existing self storage properties in our portfolio, and/or (iii) joint ventures with third parties for the acquisition and expansion of self storage properties.

On July 8, 2024, in connection with the Second Amended Credit Facility Loan Agreement, the Company entered into a swap transaction for an interest rate derivative with Huntington (the "Cap Rate Agreement") effective July 10, 2024. The notional amount and strike is $7,500,000 and 5.25%, respectively. The cost of the initial premium was $57,000 and will be carried as an asset on the balance sheet at fair value. The Cap Rate Agreement terminates on July 6, 2027.

We continue to actively review a number of store and store portfolio acquisition opportunities and have been working to further develop and expand our current stores. We did not complete any acquisitions in the three and nine months ended September 30, 2024. In addition, we may pursue third-party management opportunities of properties owned by certain affiliates or joint venture partners for a fee, and utilize such relationships with third-party owners as a source for future acquisitions and investment opportunities. As of September 30, 2024, under our third-party management platform, Global MaxManagementSM, we managed one third-party owned property, which was previously rebranded as “Global Self Storage,” had 137,318-leasable square feet and was comprised of 619 climate-controlled and non-climate-controlled units located in Edmond, Oklahoma.

We expect we will have sufficient cash from current sources to meet our liquidity needs for the next twelve months because our capital resources currently exceed our projected expenses for the next twelve months. However, we may opt to supplement our equity capital and increase potential returns to our stockholders through the use of prudent levels of borrowings. We may use debt when the available terms and conditions are favorable to long-term investing and well-aligned with our strategic business plan.

The Company currently has capital resources totaling approximately $25.1 million, comprised of $6.9 million of cash, cash equivalents, and restricted cash and $3.2 million of marketable securities as of September 30, 2024, and $15 million available for

withdrawal under the Second Amended Credit Facility Loan Agreement which matures on July 6, 2027. Capital resources derived from retained cash flow have been and are currently expected to continue to be negligible. Retained operating cash flow represents our expected cash flow provided by operating activities, less stockholder distributions and capital expenditures to maintain stores. These capital resources allow us to continue to execute our strategic business plan, which includes funding acquisitions, either directly or through joint ventures; expansion projects at our existing properties; and broadening our revenue base and pipeline of potential acquisitions through developing Global MaxManagementSM, our third-party management platform. Our board of directors regularly reviews our strategic business plan, including topics and metrices like capital formation, debt versus equity ratios, dividend policy, use of capital and debt, funds from operations (“FFO”) and adjusted funds from operations (“AFFO”) performance, and optimal cash levels. See the section titled "Non-GAAP Financial Measures" for the definition and use of FFO and AFFO.

We expect that the results of our operations will be affected by a number of factors. Many of the factors that will affect our operating results are beyond our control. The Company and its properties could be materially and adversely affected by the risks, or the public perception of the risks, related to, among other things, public health crises, natural disasters and geopolitical events, including the ongoing conflict between Russia, Belarus and Ukraine, the ongoing conflict between Israel and Hamas, financial and credit market volatility and disruptions, inflationary pressures, rising interest rate fluctuations, supply chain issues, labor shortages and recessionary concerns.

 

Results of Operations for the Three Months Ended September 30, 2024 Compared with the Three Months Ended September 30, 2023

Revenues

Total revenues increased from $3,090,374 during the three months ended September 30, 2023 to $3,200,276 during the three months ended September 30, 2024, an increase of 3.6%, or $109,902. Rental income increased from $2,968,263 during the three months ended September 30, 2023 to $3,070,871 during the three months ended September 30, 2024, an increase of 3.5%, or $102,608. The increase was primarily attributable to increases in occupancy and existing tenant rates under our proprietary revenue rate management program, which was partially offset by lower move-in rental rates year-over-year across the United States and in the markets that we operate.

 

Other property related income consists of tenant insurance fees, sales of storage supplies, and other ancillary revenues. Other property related income increased from $103,676 during the three months ended September 30, 2023 to $111,618 during the three months ended September 30, 2024, an increase of 7.7%, or $7,942. The increase was primarily attributable to additional tenants subscribing to tenant insurance.

 

Income from our third-party management platform consists of management fees and customer insurance fees. Management fees and other income decreased from $18,435 during the three months ended September 30, 2023 to $17,787 during the three months ended September 30, 2024. The decrease was primarily attributable to the adjustment of fees for our third-party management services in accordance with current market rates.

Operating Expenses

The increase in general and administrative expenses during this period are primarily attributable to increased professional fees and employment costs.

Depreciation and amortization decreased from $409,245 during the three months ended September 30, 2023 to $409,227 during the three months ended September 30, 2024.

Business development which includes capital raising, store acquisition, and third-party management marketing expenses decreased from $5,903 during the three months ended September 30, 2023 to $2,012 during the three months ended September 30, 2024, a decrease of 65.9%, or $3,891. These costs primarily consist of costs incurred in connection with business development, capital raising, and future potential store acquisitions, and third-party management marketing expenses. Business development costs are typically non-recurring and fluctuate based on periodic business development and acquisition activity.

Other income (expense)

Interest expense on debt increased from $619,550 during the nine months ended September 30, 2023 to $675,622 during the nine months ended September 30, 2024. This increase was attributable to the change in fair value of the interest rate cap partially offset by cash settlements under the interest rate cap from the difference between the reference interest rate and the strike rate and lower interest payments under the Term Loan Agreement. The cash payments for the $20 million Term Loan Agreement remain the same every month until June 2036 and are $107,699 per month.

Dividend, interest, and other income was $194,960 during the nine months ended September 30, 2023 and $211,030 during the nine months ended September 30, 2024. The increase was attributable to the dividends earned on money market mutual fund balances.

The Company’s closing market price as of September 30, 2024 and September 30, 2023 was $5.21 and $4.86, respectively. Past market price performance and distribution levels do not guarantee similar results in the future.

 

Non-GAAP Financial Measures

Funds from Operations (“FFO”) and FFO per share are non-GAAP measures defined by the National Association of Real Estate Investment Trusts (“NAREIT”) and are considered helpful measures of REIT performance by REITs and many REIT analysts. NAREIT defines FFO as a REIT’s net income, excluding gains or losses from sales of property, and adding back real estate depreciation and amortization. The Company also excludes changes in unrealized gains or losses on marketable equity securities. FFO and FFO per share are not a substitute for net income or earnings per share. FFO is not a substitute for GAAP net cash flow in evaluating our liquidity or ability to pay dividends, because it excludes financing activities presented on our statements of cash flows. In addition, other REITs may compute these measures differently, so comparisons among REITs may not be helpful. However, the Company believes that to further understand the performance of its stores, FFO should be considered along with the net income and cash flows reported in accordance with GAAP and as presented in the Company’s financial statements.

Adjusted FFO (“AFFO”) and AFFO per share are non-GAAP measures that represent FFO and FFO per share excluding the effects of stock-based compensation, business development, capital raising, and acquisition related costs and non-recurring items, which we believe are not indicative of the Company’s operating results. AFFO and AFFO per share are not a substitute for net income or earnings per share. AFFO is not a substitute for GAAP net cash flow in evaluating our liquidity or ability to pay dividends, because it excludes financing activities presented on our statements of cash flows. We present AFFO because we believe it is a helpful measure in understanding our results of operations insofar as we believe that the items noted above that are included in FFO, but excluded from AFFO, are not indicative of our ongoing operating results. We also believe that the analyst community considers our AFFO (or similar measures using different terminology) when evaluating us. Because other REITs or real estate companies may not compute AFFO in the same manner as we do, and may use different terminology, our computation of AFFO may not be comparable to AFFO reported by other REITs or real estate companies. However, the Company believes that to further understand the performance of its stores, AFFO should be considered along with the net income and cash flows reported in accordance with GAAP and as presented in the Company’s financial statements.

---

We believe net operating income or “NOI” is a meaningful measure of operating performance because we utilize NOI in making decisions with respect to, among other things, capital allocations, determining current store values, evaluating store performance, and in comparing period-to-period and market-to-market store operating results. In addition, we believe the investment community utilizes NOI in determining operating performance and real estate values and does not consider depreciation expense because it is based upon historical cost. NOI is defined as net store earnings before general and administrative expenses, interest, taxes, depreciation, and amortization.

NOI is not a substitute for net income, net operating cash flow, or other related GAAP financial measures, in evaluating our operating results.

Same-Store Self Storage Operations

We consider our same-store portfolio to consist of only those stores owned and operated on a stabilized basis at the beginning and at the end of the applicable periods presented. We consider a store to be stabilized once it has achieved an occupancy rate that we believe, based on our assessment of market-specific data, is representative of similar self storage assets in the applicable market for a full year measured as of the most recent January 1 and has not been significantly damaged by natural disaster or undergone significant renovation or expansion. We believe that same-store results are useful to investors in evaluating our performance because they provide information relating to changes in store-level operating performance without taking into account the effects of acquisitions, dispositions, or new ground-up developments. At September 30, 2024, we owned twelve same-store properties and zero non same-store properties. The Company believes that by providing same-store results from a stabilized pool of stores, with accompanying operating metrics including, but not limited to, variances in occupancy, rental revenue, operating expenses, and NOI, stockholders and potential investors are able to evaluate operating performance without the effects of non-stabilized occupancy levels, rent levels, expense levels, acquisitions, or completed developments. Same-store results should not be used as a basis for future same-store performance or for the performance of the Company’s stores as a whole.

Same-store occupancy at September 30, 2024 increased by 1.7% to 91.5% from 89.8% at September 30, 2023.

Same-store revenues increased by 3.6% and 1.5% for the three and nine months ended September 30, 2024 versus the same periods in 2023. Same-store cost of operations decreased by 0.8% and increased 5.4% for the three and nine months ended September 30, 2024 versus the same periods in 2023. Same-store NOI increased by 6.3% and decreased 0.7% for the three and nine months ended September 30, 2024 versus the same periods in 2023. The increase in same-store NOI during the three months ended September 30, 2024 was due primarily to an increase in revenues and decrease in cost of operations.

We believe that our results were driven by, among other things, our internet and digital marketing initiatives which helped maintain our overall average same-store occupancy of approximately 92% as of September 30, 2024. Also, contributing to our results were our customer service efforts which we believe were essential in building local brand loyalty, resulting in strong referral and word-of-mouth market demand for our storage units and services. Another contributing factor to our results was our competitor move-in rate metrics analysis which employs internet data scraping and other methods to help keep our storage unit move-in rates “in the market,” and our revenue rate management program which helped increase existing tenant rates while optimizing store occupancy.

These results are summarized as follows:

Analysis of Same-Store Revenue

For the three and nine months ended September 30, 2024, same-store revenue increased 3.6%, or $110,550, and 1.5%, or $139,695, respectively, versus the same periods in 2023. Same-store average overall square foot occupancy for all of the Company’s same-store properties increased to 91.5% at September 30, 2024, up from 89.8% at September 30, 2023.

We believe that our focus on maintaining high occupancy helps us to maximize rental income at our properties. We seek to maintain an average square foot occupancy level at or above 90% by regularly adjusting the rental rates and promotions offered to attract new tenants as well as adjusting our online marketing efforts in seeking to generate sufficient move-in volume to replace tenants that vacate. Demand may fluctuate due to various local and regional factors, including the overall economy. Demand is generally higher in the summer months than in the winter months and, as a result, rental rates charged to new tenants are typically higher in the summer months than in the winter months.

As of September 30, 2024, we observed no material degradation in rent collections. However, we believe that our bad debt losses could increase from historical levels, due to (i) cumulative stress (such as inflation, recession fears, etc.) on our customers’ financial capacity and (ii) reduced rent recoveries from auctioned units.

---

We may experience a change in the move-out patterns of our long-term customers due to economic uncertainty. This could lead to lower occupancies and rent “roll down” as long-term customers are replaced with new customers at lower rates.

We currently expect rental income growth, if any, to come from a combination of the following: (i) continued existing tenant rent increases, (ii) higher rental rates charged to new tenants, (iii) lower promotional discounts, and (iv) higher occupancies. Our future rental income growth will likely also be dependent upon many factors for each market that we operate in, including, among other things, demand for self storage space, the level of competitor supply of self storage space, and the average length of stay of our tenants. Increasing existing tenant rental rates, generally on an annual basis, is a key component of our revenue growth. We typically determine the level of rental increases based upon our expectations regarding the impact of existing tenant rate increases on incremental move-outs. We currently expect existing tenant rent increases for the remainder of 2024, if any, to be similar to those in the prior year.

It is difficult to predict trends in move-in, move-out, in place contractual rents, and occupancy levels. Current trends, when viewed in the short-term, are volatile and not necessarily predictive of our revenues going forward because they may be subject to many short-term factors. Such factors include, among others, initial move-in rates, seasonal factors, unit size and geographical mix of the specific tenants moving in or moving out, the length of stay of the tenants moving in or moving out, changes in our pricing strategies, and the degree and timing of rate increases previously passed to existing tenants.

Importantly, we continue to refine our ongoing revenue rate management program which includes regular internet data scraping of local competitors’ prices. We do this in seeking to maintain our competitive market price advantage for our various sized storage units at our stores. This program helps us in seeking to maximize each store’s occupancies and our self storage revenue and NOI. We believe that, through our various marketing initiatives, we can continue to attract high quality, long term tenants who we expect will be storing with us for years. As of September 30, 2024, our average tenant duration of stay was approximately 3.4 years, which was up from 3.3 years as of September 30, 2023.

Analysis of Same-Store Cost of Operations

For the three and nine months ended September 30, 2024, same-store cost of operations decreased 0.8%, or $9,117, and increased 5.4%, or $181,853, respectively, versus the same periods in 2023. This decrease in same-store cost of operations for the three months ended September 30, 2024 was due primarily to decreased expenses for real estate property taxes.

Employment. On-site store manager, regional manager, and district manager payroll expense increased 3.8%, or $12,601, and 9.1%, or $89,437, for the three and nine months ended September 30, 2024, respectively, versus the same periods in 2023. The increase was due primarily to routine employee hiring and inflationary increases in compensation rates for existing employees. We currently expect inflationary increases in compensation rates for existing employees and other increases in compensation costs as we potentially add new stores.

Real Estate Property Tax. Store property tax expense decreased 6.4%, or $27,165, and increased 0.4%, or $4,693, for the three and nine months ended September 30, 2024, respectively, versus the same periods in 2023. When compared to store property tax expense for the three months ended September 30, 2024, we currently expect store property tax expense to be consistent during the rest of 2024. See the section titled “Property Tax Expenses at Dolton, IL” for additional detail regarding property tax relief obtained for our Dolton, IL property in 2024, which will partially offset our increased real estate property taxes.

Administrative. We classify administrative expenses as bank charges related to processing the stores’ cash receipts, credit card fees, repairs and maintenance, utilities, landscaping, alarm monitoring and trash removal. Administrative expenses decreased 2.2%, or $4,727, and increased 1.5%, or $9,439, in the three and nine months ended September 30, 2024, respectively, versus the same periods in 2023. We experienced a decrease in administrative expenses for the three months ended September 30, 2024 due primarily to decreased repairs and maintenance expenses. We currently expect moderate increases in other direct store costs in 2024.

Repairs and Maintenance. Repairs and maintenance expense decreased 19.8%, or $10,883, and 8.2%, or $11,998, for the three and nine months ended September 30, 2024, respectively, versus the same periods in 2023. These expenses decreased during the three months ended September 30, 2024 versus the same period in 2023 primarily due to one-off repairs and maintenance completed in the three months ended September 30, 2023.

Utilities. Our utility expenses are currently comprised of electricity, oil, and gas costs, which vary by store and are dependent upon energy prices and usage levels. Changes in usage levels are driven primarily by weather and temperature. Also, affecting our utilities expenses over time is our ongoing LED light replacement program at all of our stores which has already resulted in lower electricity usage. Utilities expense decreased 2.2%, or $1,370, and 4.8%, or $10,032, for the three and nine months ended September 30, 2024, respectively, versus the same periods in 2023. It is difficult to estimate future utility costs because weather, temperature, and energy prices are volatile and unpredictable. However, based upon current trends and expectations regarding commercial electricity

---

rates, we currently expect inflationary increases in rates combined with lower usage resulting in similar utility costs for the remainder of 2024.

Landscaping. Landscaping expenses, which include snow removal costs, increased 2.2%, or $571, and 15.8%, or $11,880, for the three and nine months ended September 30, 2024, respectively, versus the same periods in 2023. The increase in landscaping expense during the three and nine months ended September 30, 2024 versus the same periods in 2023 was primarily due to an increase of one-off snow removal and inflationary increases during the nine months ended September 30, 2024. Landscaping expense levels are dependent upon many factors such as weather conditions, which can impact landscaping needs including, among other things, snow removal, inflation in material and labor costs, and random events. We currently expect inflationary increases in landscaping expense for the remainder of 2024, excluding snow removal expense, which is primarily weather dependent and unpredictable.

Marketing. Marketing expense is comprised principally of internet advertising and the operating costs of our 24/7 kiosk and telephone call and reservation center. Marketing expense varies based upon demand, occupancy levels, and other factors. Internet advertising, in particular, can increase or decrease significantly in the short term in response to these factors. Marketing expense decreased 5.4%, or $4,604, and 1.3%, or $3,420, for the three and nine months ended September 30, 2024, respectively, versus the same periods in 2023. Marketing expense decreased during the three months ended September 30, 2024 primarily due to decreased spending on digital advertising. Based upon current trends in move-ins, move-outs, and occupancies, we currently expect marketing expense to increase at a nominal rate for the remainder of 2024.

General. Other direct store costs include general and administrative expenses incurred at the stores. General expenses include items such as store insurance, business license costs, and the cost of operating each store’s rental office including supplies and telephone and data communication lines. General expenses increased 20.7%, or $19,112, and 38.4%, or $92,729, for the three and nine months ended September 30, 2024, respectively, versus the same periods in 2023, primarily due to increased expense for property insurance, recruitment and training, uniforms, and branded merchandise to support our customer loyalty program. We currently expect moderate increases in direct store costs during the remainder of 2024.

Lien Administration. Lien administration expenses increased 21.0%, or $1,142, and 6.6%, or $955, in the three and nine months ended September 30, 2024, respectively, versus the same periods in 2023.

Property Tax Expenses at Dolton, IL

 

Late in the third quarter of 2017, our Dolton, IL property was reassessed by the municipality and separately, our Class 8 tax incentive renewal hearing was held. As a result of those two events, our Dolton, IL property was reassessed at approximately 52% higher and the Class 8 tax incentive was not renewed. These events were applied retroactively to take effect on January 1, 2017. Property tax expenses have increased to $399,000 during 2020, $417,000 during 2021, $532,000 during 2022, and $559,000 during 2023. The Class 8 tax incentive phased out over the years 2017, 2018, 2019, 2020 and 2021. In 2024, tax relief was granted resulting in an approximate 17.9% reduction in tax liability to the real estate property taxes for our Dolton, IL property. We are continuing to appeal the property tax reassessment and our Class 8 tax incentive renewal status for further tax relief. However, there is no guarantee that either the assessment will be reduced or our Class 8 tax incentive status will be reinstated.

Analysis of Global Self Storage Store Expansions and Redevelopment Operations

 

In addition to actively reviewing a number of store and portfolio acquisition candidates, we have been working to further redevelop and expand our current stores. In 2020, we completed three expansion / conversion projects at our properties located in Millbrook, NY, McCordsville, IN, and West Henrietta, NY. In 2021 and 2023, we completed conversion projects at our property located in Lima, OH.

In 2019, the Company broke ground on the Millbrook, NY expansion, which added approximately 11,800 leasable square feet of all-climate-controlled units. Upon completion in February 2020, the Millbrook, NY store's area occupancy dropped from approximately 88.6% to approximately 45.5%. As of June 30, 2021, the Millbrook, NY store’s total area occupancy was approximately 95.4%.

In the first quarter of 2020, the Company began reviewing plans to convert certain commercially-leased space to all-climate-controlled units at the McCordsville, IN property. In April 2020, the Company commenced such conversion, which resulted in a new total of 535 units and 76,360 leasable square feet at the McCordsville, IN property. Upon completion in June 2020, the McCordsville, IN store's total area occupancy dropped from what would have been approximately 97.4% to approximately 79.1%. As of June 30, 2021, the McCordsville, IN store’s total area occupancy was approximately 94.7%.

Our West Henrietta, NY store expansion project, completed in August 2020, added approximately 7,300 leasable square feet of drive-up storage units. Upon completion of the expansion project, West Henrietta, NY’s total area occupancy dropped from approximately 89.6% to approximately 77.9%. As of June 30, 2021, the West Henrietta, NY store’s total area occupancy was approximately 89.1%.

In 2021, the Company began reviewing plans to convert certain commercially-leased spaces to approximately 3,000 leasable square feet of all-climate-controlled units at the Lima, OH property. In July 2021, the Company completed such conversion, resulting in a new total of 756 units and 96,883 leasable square feet at the Lima, OH property. Upon completion, total area occupancy was approximately 94.8%. This conversion did not constitute a significant renovation or expansion because it only added approximately 3,000 leasable square feet of self storage to the property. As such, our Lima, OH property remained a same store property.

In 2022, the Company began reviewing plans to convert certain commercially-leased spaces to approximately 2,500 leasable square feet of all-climate-controlled units at the Lima, OH property. In January 2023, the Company completed such conversion, resulting

---

in a new total of 767 units and 94,928 leasable square feet at the Lima, OH property. Upon completion, total area occupancy was approximately 91.1%. This conversion did not constitute a significant renovation or expansion because it only added approximately 2,500 leasable square feet of self storage to the property. As such, our Lima, OH property remained a same store property.

Analysis of Realized and Unrealized Gains (Losses)

Unrealized gains and losses on the Company’s investment in marketable equity securities for the nine months ended September 30, 2024 and 2023 were a gain of $403,935 and a loss of $165,266, respectively. As we continue to acquire and/or develop additional stores, as part of the funding for such activities, we may liquidate our investment in marketable equity securities and potentially realize gains or losses. As of September 30, 2024, our cumulative unrealized gain on marketable equity securities was $2,423,477. There were no realized gains or losses for the nine months ended September 30, 2024.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Not applicable.

 

Item 4. Controls and Procedures.

Disclosure Controls and Procedures.

We maintain disclosure controls and procedures to ensure that information required to be disclosed in the reports we file pursuant to the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based on the definition of “disclosure controls and procedures” in Rule 13a-15(e) of the Exchange Act. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can only provide a reasonable assurance of achieving the desired control objectives, and in reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We have a disclosure controls and procedures committee, comprised of the Chief Executive Officer and Chief Financial Officer, which meets as necessary and is responsible for considering the materiality of information and determining our disclosure obligations on a timely basis.

The disclosure controls and procedures committee carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Changes in internal control over financial reporting.

There were no changes in our internal control over financial reporting (as such term is defined in Exchange Act Rule 13a-15(f)) that occurred during our most recent quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES   Basis of Presentation The accompanying unaudited consolidated financial statements of the Company are presented on the accrual basis of accounting in accordance with accounting standards generally accepted in the United States of America ("GAAP") for interim financial information, and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they may not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (including normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. The consolidated balance sheet as of December 31, 2023 has been derived from the Company’s audited financial statements as of that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2023. Cash, Cash Equivalents, and Restricted Cash The Company’s cash is deposited with financial institutions located throughout the United States and at times may exceed federally insured limits. Cash equivalents may consist of money market fund shares and may include, among other things, highly liquid investments purchased with an original maturity of three months or less. Restricted cash is comprised of escrowed funds deposited with a bank relating to capital expenditures. The carrying amount reported on the balance sheet for cash, cash equivalents, and restricted cash approximates fair value. The following table provides a reconciliation of cash, cash equivalents, and restricted cash in our unaudited consolidated balance sheets to the total amount shown in our consolidated statements of cash flows:       September 30, 2024     December 31, 2023   Cash and cash equivalents   $ 6,762,074     $ 6,921,779   Restricted cash     165,060       106,767   Total cash, cash equivalents, and restricted cash as shown in our unaudited consolidated statements of cash flows   $ 6,927,134     $ 7,028,546     Income Taxes The Company has elected to be treated as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). In order to maintain its qualification as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its stockholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax with respect to that portion of its income which meets certain criteria and is distributed annually to stockholders. The Company plans to continue to operate so that it meets the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. If the Company were to fail to meet these requirements, it would be subject to federal income tax. In management's opinion, the requirements to maintain these elections are being fulfilled. The Company is subject to certain state and local taxes. The Company has elected to treat its corporate subsidiary, SSG TRS LLC, as a taxable REIT subsidiary (“TRS”). In general, the Company’s TRS may perform additional services for tenants and may engage in any real estate or non-real estate related business. A TRS is subject to federal corporate income tax. The Company recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. The Company has reviewed its tax positions and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on federal, state, and local income tax returns for open tax years (2021 – 2023), or are expected to be taken in the Company’s 2024 tax returns. Marketable Equity Securities Investments in equity securities that have readily determinable fair values are measured at fair value. Gains or losses from changes in the fair value of equity securities are recorded in net income, until the investment is sold or otherwise disposed. The specific identification method is used to determine the realized gain or loss on investments sold or otherwise disposed. Fair value is determined using a valuation hierarchy generally by reference to an active trading market, using quoted closing or bid prices. Judgment is used to ascertain if a formerly active market has become inactive and in determining fair values when markets have become inactive. Real Estate Assets Real estate assets are carried at cost, less accumulated depreciation. Direct and allowable internal costs associated with the development, construction, renovation, and improvement of real estate assets are capitalized. Property taxes and other costs associated with development incurred during a construction period are capitalized. A construction period begins when expenditures for a real estate asset have been made and activities that are necessary to prepare the asset for its intended use are in progress. A construction period ends when an asset is substantially complete and ready for its intended use.   Acquisition costs are generally capitalized for acquisitions that qualify as asset acquisitions. When properties are acquired, the purchase price is allocated to the tangible and intangible assets acquired and liabilities assumed based on estimated fair values. Allocations to land, building and improvements, and equipment are recorded based upon their respective fair values as estimated by management. In allocating the purchase price for an acquisition, the Company determines whether the acquisition includes intangible assets or liabilities. The Company allocates a portion of the purchase price to an intangible asset attributed to the value of in-place leases. This intangible is generally amortized to expense over the expected remaining term of the respective leases. Substantially all of the leases in place at acquired properties are at market rates, as the majority of the leases are month-to-month contracts. Repairs and maintenance costs are charged to expense as incurred. Major replacements and betterments that improve or extend the life of the asset are capitalized and depreciated over their estimated useful lives. Depreciation is computed using the straight-line method over the estimated useful lives of the buildings and improvements, which are generally between 5 and 39 years. Derivative Financial Instruments The Company carries all derivative financial instruments on the balance sheet at fair value. Fair value of derivatives is determined by reference to observable prices that are based on inputs not quoted on active markets, but corroborated by market data. The accounting for changes in the fair value of a derivative instrument depends on whether the derivative has been designated and qualifies as part of a hedging relationship. The Company’s use of derivative instruments has been limited to an interest rate cap agreement. For derivative instruments not designated as cash flow hedges, the unrealized gains and losses are included in interest expense in the accompanying statements of operations. For derivatives designated as cash flow hedges, the effective portion of the changes in the fair value of the derivatives is initially reported in accumulated other comprehensive income in the Company’s balance sheets and subsequently reclassified into earnings when the hedged transaction affects earnings. The valuation analysis of the interest rate cap reflects the contractual terms of derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. Accounts Payable and Accrued Expenses Accounts payable and accrued expenses generally consist of property tax accruals, unearned rental income, and trade payables. Revenue and Expense Recognition Revenues from stores, which are primarily composed of rental income earned pursuant to month-to-month leases for storage space, as well as associated late charges and administrative fees, are recognized as earned in accordance with ASC Topic 842, Leases. Promotional discounts reduce rental income over the promotional period. Ancillary revenues from sales of merchandise and tenant insurance and other income are recognized as earned in accordance with ASC Topic 606, Revenue from Contracts with Customers ("ASC 606"). The Company's management fees are earned subject to the terms of the related property management services agreements (“PSAs”). These PSAs provide that the Company will perform management services, which include leasing and operating the property and providing accounting, marketing, banking, maintenance and other services. These services are provided in exchange for monthly management fees, which are based on a percentage of revenues collected from stores owned by third parties. PSAs generally have original terms of three years, after which management services are provided on a month-to-month basis unless terminated. Management fees are due on the last day of each calendar month that management services are provided. The Company accounts for the management services provided to a customer as a single performance obligation which are rendered over time each month in accordance with ASC 606. The total amount of consideration from the contract is variable as it is based on monthly revenues, which are influenced by multiple factors, some of which are outside the Company's control. No disaggregated information relating to PSAs is presented as the Company currently has only one contract. General and administrative expenses and property operations expenses, which may include among other expenses, property taxes, utilities, repairs and maintenance, and other expenses, are expensed as incurred. The Company accrues for property tax expense based upon actual amounts billed and, in some circumstances, estimates and historical trends when bills or assessments have not been received from the taxing authorities or such bills and assessments are in dispute. Evaluation of Asset Impairment The Company evaluates its real estate assets and intangible assets, if any, for indicators of impairment. If there are indicators of impairment and we determine that the asset is not recoverable from future undiscounted cash flows to be received through the asset’s remaining life (or, if earlier, the expected disposal date), we record an impairment charge to the extent the carrying amount exceeds the asset’s estimated fair value or net proceeds from expected disposal. The Company evaluates goodwill for impairment annually and whenever relevant events, circumstances, and other related factors indicate that fair value may be less that carrying amounts. If it is determined that the carrying amount of goodwill exceeds the amount that would be allocated to goodwill if the reporting unit were acquired for estimated fair value, an impairment charge is recorded. There were no indicators of impairment to goodwill and real estate assets as of September 30, 2024, and no impairment charges were recorded for any periods presented herein.   Stock-based Compensation   The measurement and recognition of compensation expense for all stock-based compensation awards to employees and independent directors are based on estimated fair values. Awards granted are measured at fair value and any compensation expense is recognized over the service periods of each award. For awards granted which contain a graded vesting schedule and the only condition for vesting is a service condition, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For awards granted for which vesting is subject to a performance condition, compensation cost is recognized over the requisite service period if and when the Company concludes it is probable that the performance condition will be achieved. The estimated number of stock awards that will ultimately vest requires judgment, and to the extent actual results or updated estimates differ from our current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised.   Loan Procurement Costs   Loan procurement costs on the Company's term loan note payable are presented as a direct deduction from the carrying amount of the related debt liability. The loan procurement costs related to the term loan note payable are amortized using the effective interest method over the life of the loan. Loan procurement costs associated with the Company's revolving line of credit remain in line of credit issuance costs, net of amortization on the Company's consolidated balance sheets. The costs related to the revolving line of credit are amortized using the straight-line method, which approximates the effective interest method, over the estimated life of the related debt. Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from management's estimates. Recently Issued Accounting Standards In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07 – Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amended guidance requires the disclosure of incremental segment information, including significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and a reconciliation of segment profit or loss to net income. The title and position of the CODM must also be disclosed, along with how the CODM uses the reported measures to assess segment performance and to allocate resources. Entities with a single reportable segment (such as the Company) will be required to provide the disclosures required by Topic 280, as amended.

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. FAIR VALUE MEASUREMENTS The Company applies the methods of determining fair value to value its financial assets and liabilities. The application of fair value measurements may be on a recurring or nonrecurring basis depending on the accounting principles applicable to the specific asset or liability or whether management has elected to carry the item at its estimated fair value. The hierarchy of valuation techniques is based on whether the inputs to those techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy: Level 1 — Quoted prices in active markets for identical instruments or liabilities. Level 2 — Prices determined using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing an asset or liability and are developed based on market data obtained from sources independent of the Company. These may include quoted prices for similar assets and liabilities, interest rates, prepayment speeds, credit risk, and market-corroborated inputs. Level 3 — Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Company’s own assumptions about the factors that market participants use in pricing an asset or liability and are based on the best information available in the circumstances. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when estimating fair value. The valuation method used to estimate fair value may produce a fair value measurement that may not be indicative of ultimate realizable value. Furthermore, while management believes its valuation methods are appropriate and consistent with those used by other market participants, the use of different methods or assumptions to estimate the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Those estimated values may differ significantly from the values that would have been used had a readily available market for such loans or investments existed, or had such loans or investments been liquidated, and those differences could be material to the financial statements. Fair valued assets consist of shares of marketable equity securities and an interest rate cap. The value of the equity securities is based on a traded market price and is considered to be a level 1 measurement, and the value of the interest rate cap is based on its maturity and observable market-based inputs including interest rate curves and is considered to be a level 2 measurement. The following table provides the assets and liabilities carried at fair value measured on a recurring basis as of September 30, 2024 and December 31, 2023: September 30, 2024   Level 1     Level 2     Level 3     Total   Assets                         Marketable equity securities   $ 3,178,964     $ —     $ —     $ 3,178,964   Interest rate cap derivative   —       10,768       —       10,768   Total assets at fair value   $ 3,178,964     $ 10,768     $ —     $ 3,189,732                             December 31, 2023   Level 1     Level 2     Level 3     Total   Assets                         Marketable equity securities   $ 2,775,029     $ —     $ —     $ 2,775,029   Interest rate cap derivative   —       50,881       —       50,881   Total assets at fair value   $ 2,775,029     $ 50,881     $ —     $ 2,825,910     There were no assets transferred from level 1 to level 2 as of September 30, 2024. The Company did not have any level 3 assets or liabilities as of September 30, 2024.   The fair values of financial instruments including cash and cash equivalents, restricted cash, accounts receivable, and accounts payable and accrued expenses approximated their respective carrying values as of September 30, 2024. The estimated fair value of the Company’s outstanding debt was approximately $14,466,115 as of September 30, 2024. This estimate was based on market interest rates for comparable obligations, general market conditions, and maturity.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	6. DERIVATIVES The Company’s objective in using an interest rate derivative is to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company uses an interest rate cap to manage interest rate risk. The Company carries the initial premium paid for the interest rate cap as an asset on the balance sheet at fair value. The change in the unrealized gain or loss of the initial premium is recorded as an increase or decrease to interest expense.   The following table summarizes the terms of the Company’s derivative financial instrument:         Notional Amount           Effective   Maturity Product   September 30, 2024       Strike   Date   Date Cap Agreement   $ 7,500,000       5.25%   7/10/2024   7/6/2027                           Notional Amount           Effective   Maturity Product   December 31, 2023       Strike   Date   Date Cap Agreement   $ 7,500,000       3.75%   12/20/2021   7/6/2024 The Company is potentially exposed to credit loss in the event of non-performance by the counterparty.

Notes Payable [Abstract]
Note Payable and Revolving Line of Credit	7. NOTE PAYABLE AND REVOLVING LINE OF CREDIT   Note Payable On June 24, 2016, certain wholly owned subsidiaries (“Term Loan Secured Subsidiaries”) of the Company entered into a loan agreement and certain other related agreements (collectively, the “Term Loan Agreement”) between the Term Loan Secured Subsidiaries and Insurance Strategy Funding IV, LLC (the “Lender”). Under the Term Loan Agreement, the Term Loan Secured Subsidiaries borrowed from the Lender in the principal amount of $20 million pursuant to a promissory note (the “Term Loan Promissory Note”). The Term Loan Promissory Note bears an interest rate equal to 4.192% per annum and is due to mature on July 1, 2036. Pursuant to a security agreement (the “Term Loan Security Agreement”), the obligations under the Term Loan Agreement are secured by certain real estate assets owned by the Term Loan Secured Subsidiaries. The Company entered into a non-recourse guaranty on June 24, 2016 (the “Term Loan Guaranty,” and together with the Term Loan Agreement, the Term Loan Promissory Note and the Term Loan Security Agreement, the “Term Loan Documents”) to guarantee the payment to the Lender of certain obligations of the Term Loan Secured Subsidiaries under the Term Loan Agreement. The Term Loan Documents require the Term Loan Secured Subsidiaries and the Company to comply with certain covenants, including, among others, a minimum net worth test and other customary covenants. The Lender may accelerate amounts outstanding under the Term Loan Documents upon the occurrence of an event of default (as defined in the Term Loan Agreement) including, but not limited to, the failure to pay amounts due or commencement of bankruptcy proceedings. As of September 30, 2024, the Company was in compliance with these covenants. The Company incurred loan procurement costs of $646,246 and such costs have been recorded as a reduction of the note payable on the consolidated balance sheet and are amortized as an adjustment to interest expense over the term of the loan. The Company recorded amortization expense of $8,943 and $9,247 for the three months ended September 30, 2024 and 2023, respectively and $27,060 and $27,962 for the nine months ended September 30, 2024 and 2023, respectively. As of September 30, 2024 and December 31, 2023, the carrying value of the Company’s note payable is summarized as follows: Note Payable   September 30, 2024     December 31, 2023   Principal balance outstanding   $ 16,811,550     $ 17,244,687   Less: Loan procurement costs, net     (316,408 )     (343,468 ) Total note payable, net   $ 16,495,142     $ 16,901,219     As of September 30, 2024, the note payable was secured by certain of the Company’s self storage properties with an aggregate net book value of approximately $23.4 million. The following table represents the future principal payment requirements on the note payable as of September 30, 2024:   2024 (3 months)   $ 147,941   2025     607,488   2026     633,449   2027     660,519   2028     688,746   2029 and thereafter     14,073,407   Total principal payments   $ 16,811,550       Revolving Line of Credit On July 6, 2024, certain wholly owned subsidiaries (“Second Amended Credit Facility Secured Subsidiaries”) of the Company entered into a second amendment to the Credit Facility Loan Agreement (collectively, the “Second Amended Credit Facility Loan Agreement”) between the Second Amended Credit Facility Secured Subsidiaries and The Huntington National Bank ("Huntington"), successor by merger to TCF National Bank (“Second Amended Credit Facility Lender”). Under the Second Amended Credit Facility Loan Agreement, the Second Amended Credit Facility Secured Subsidiaries may borrow from the Second Amended Credit Facility Lender in the principal amount of up to $15 million, reduced to $14.75 million and $14.5 million in years two and three, respectively, pursuant to a promissory note (the “Second Amended Credit Facility Promissory Note”). The Second Amended Credit Facility Promissory Note bears an interest rate equal to 3% plus the greater of the SOFR or 0.25% and is due to mature on July 6, 2027, with an option to extend the maturity to July 6, 2028. As of September 30, 2024, the effective interest rate was approximately 8.20%. An annual unused facility fee is charged based on the daily average of the unadvanced amount of the Second Amended Credit Facility Loan Agreement during the trailing twelve month period ending each June 30. The fee will be calculated at 0.25% per annum if the daily average of the unadvanced amount of the Second Amended Credit Facility Loan Agreement during such trailing twelve month period was greater than fifty percent, and will be calculated at 0.15% if the daily average of the unadvanced amount of the Second Amended Credit Facility Loan Agreement during such trailing twelve month period was less than or equal to fifty percent. The obligations under the Second Amended Credit Facility Loan Agreement are secured by certain real estate assets owned by the Second Amended Credit Facility Secured Subsidiaries. The Company entered into a second amended and restated guaranty of payment as of July 6, 2024 (“Second Amended Credit Facility Guaranty,” and together with the Second Amended Credit Facility Loan Agreement, the Second Amended Credit Facility Promissory Note and related instruments, the “Second Amended Credit Facility Loan Documents”) to guarantee the payment to the Second Amended Credit Facility Lender of certain obligations of the Second Amended Credit Facility Secured Subsidiaries under the Second Amended Credit Facility Loan Agreement. The Company and the Second Amended Credit Facility Secured Subsidiaries paid customary fees and expenses in connection with their entry into the Second Amended Credit Facility Loan Documents.   The Second Amended Credit Facility Loan Agreement requires the Second Amended Credit Facility Secured Subsidiaries and the Company to comply with certain covenants, including, among others, customary financial covenants. The Lender may accelerate amounts outstanding under the Loan Documents upon the occurrence of an Event of Default (as defined in the Agreement) including, but not limited to, the failure to pay amounts due the Lender or commencement of bankruptcy proceedings.   On July 8, 2024, in connection with the Second Amended Credit Facility Loan Agreement, the Company entered into a swap transaction for an interest rate derivative with Huntington (the "Cap Rate Agreement") effective July 10, 2024. The notional amount and strike is $7,500,000 and 5.25%, respectively. The cost of the initial premium was $57,000 and will be carried as an asset on the balance sheet at fair value. The Cap Rate Agreement terminates on July 6, 2027.   The Company incurred issuance costs of $235,164 and $231,926 for the July 6, 2024 Second Amended Credit Facility Loan Agreement and the prior Amended Credit Facility Loan Agreement in July 6, 2021, respectively, and such costs are amortized as an adjustment to interest expense using the straight-line method, which approximates the effective interest method, over the term of the loan. The Company recorded amortization expense of $19,597 and $25,400 for the three months ended September 30, 2024 and 2023, respectively $70,398 and $76,201 for the nine months ended September 30, 2024 and 2023, respectively. There was no outstanding loan balance under the Revolving Line of Credit as of September 30, 2024 or December 31, 2023.

Leases [Abstract]
Leases	8. LEASES Global Self Storage as Lessor The Company's property rental revenue is primarily related to rents received from tenants at its operating stores. The Company's leases with its self storage tenants are generally on month-to-month terms, include automatic monthly renewals, allow flexibility to increase rental rates over time as market conditions permit, and provide for the collection of contingent fees such as late fees. These leases do not include any terms or conditions that allow the tenants to purchase the leased space. All self-storage leases for which the Company acts as lessor have been classified as operating leases. The real estate assets related to the Company's stores are included in "Real estate assets, net" on the Company's consolidated balance sheets and are presented at historical cost less accumulated depreciation and impairment, if any. Rental income related to these operating leases is included in property rental revenue on the Company's consolidated statements of operations, and is recognized each month during the month-to-month terms at the rental rate in place during each month.   Global Self Storage as Lessee The Company is a lessee in a lease agreement for an automobile entered into November 2022 with a lease term of three years. The lease agreement does not contain any material residual value guarantees or material restrictive covenants. The Company’s lease agreement has been classified as an operating lease. Lease expense for payments related to the Company’s operating lease is recognized on a straight-line basis over the lease term. Right-of-use assets represent the Company’s right to use an underlying asset during the lease term and lease liabilities represent the Company’s obligation to make lease payments as specified in the lease. Right-of-use assets and lease liabilities related to the Company’s operating leases are recognized at the lease commencement date based on the present value of the remaining lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available surrounding the Company’s secured borrowing rates and implied secured spread at the lease commencement date in determining the present value of lease payments. The right-of-use asset also includes any lease payments made at or before lease commencement less any lease incentives. The Company had right-of-use assets and lease liabilities related to its operating leases of $21,408 and $21,408, respectively, as of September 30, 2024 and $35,726 and $35,726, respectively, as of December 31, 2023. Such amounts are amortized using a straight-line method over the term of the lease, and are included in prepaid expenses and other assets and accounts payable and accrued expenses on the Company’s consolidated balance sheets, respectively. Amortization expense was $4,818 and $4,640 for the three months ended September 30, 2024 and 2023, respectively, and $14,318 and $13,740 for the nine months ended September 30, 2024 and 2023, respectively. As of September 30, 2024, the Company’s weighted average remaining lease term and weighted average discount rate related to its operating leases were approximately 1.1 years and 3.77%, respectively. The remaining future minimum lease payments under the automobile lease are $21,882 as of September 30, 2024 and the future minimum lease payments are $5,049 and $16,833 for the years ending December 31, 2024 and 2025, respectively.

Earnings Per Share [Abstract]
Earnings Per Share	9. EARNINGS PER SHARE Earnings per share is calculated under the two-class method under which all earnings (distributed and undistributed) are allocated to each class of common stock and participating securities based on their respective rights to receive dividends. The Company grants restricted stock to certain employees under its stock-based compensation programs, which entitle recipients to receive nonforfeitable dividends during the vesting period on a basis equivalent to the dividends paid to holders of the Company's common stock, $0.01 par value per share; these unvested awards meet the definition of participating securities.

Incorporated (“Winco”), Bexil Corporation, Tuxis Corporation, and/or their affiliates (collectively with the Company, the “Affiliates”). As of September 30, 2024, certain of the Affiliates and the Company’s directors and employees may be deemed to own, in the aggregate, approximately 9.6% of the outstanding common stock. Pursuant to an arrangement between a professional employer organization (“PEO”) and the Affiliates, the PEO provides payroll, benefits, compliance, and related services for employees of the Affiliates in accordance with applicable rules and regulations under the Code and, in connection therewith, Midas Management Corporation (“MMC”), a subsidiary of Winco, acts as a conduit payer of compensation and benefits to the Affiliates’ employees including those who are concurrently employed by the Company and its Affiliates. The aggregate compensation and benefits accrued and funded by the Company to MMC were $744,527 and $720,343 for the three months ended September 30, 2024 and 2023, respectively, and $2,295,429 and $2,136,395 for the nine months ended September 30, 2024 and 2023, respectively. Expenses for various concurrently used administrative and support functions incurred by the Affiliates are allocated at cost among them. The aggregate administrative and support function expenses accrued and paid by the Company to Winco was $9,686 and $7,272 for the three months ended September 30, 2024 and 2023, respectively, and $24,750 and $21,119 for the nine months ended September 30, 2024 and 2023, respectively. The Affiliates participate in a 401(k) retirement savings plan for substantially all qualified employees. A matching expense based upon a percentage of contributions to the plan by eligible employees is incurred and allocated among the Affiliates. The matching expense is accrued and funded on a current basis and may not exceed the amount permitted as a deductible expense under the Code. The Company's allocated matching expense was $25,018 and $22,857 for the three months ended September 30, 2024 and 2023, respectively, and $82,315 and $76,671 for the nine months ended September 30, 2024 and 2023, respectively. The Company had reimbursements payable to MMC and Winco for compensation, benefits, and administrative and support function expenses of $22,825 and $23,523 as of September 30, 2024 and December 31, 2023, respectively. The Company currently reimburses monthly automobile expenses of $1,000 per month to its President, Mark C. Winmill. To the extent that the monthly payment under the Company’s automobile lease exceeds the current monthly reimbursement amount, Mr. Winmill voluntarily reimburses the Company for the excess amount. In this regard, Mr. Winmill has reimbursed the Company $8,198 and $8,198 for the automobile payments paid and due in 2024 and 2023, respectively. The Company leases office space and storage to certain Affiliates under rental agreements. The terms of occupancy are month to month and automatically renew unless terminated by either party on thirty days’ written notice.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	12. STOCK-BASED COMPENSATION On October 16, 2017 (“Effective Date”), the Company’s stockholders approved the Company’s 2017 Equity Incentive Plan (the “Plan”). The Plan is designed to provide equity-based incentives to certain eligible persons, as defined in the Plan, in the form of options, share appreciation rights, restricted stock, restricted stock units, dividend equivalent rights or other forms of equity-based compensation as determined in the discretion of the Board of Directors, the Compensation Committee of the Board of Directors, or other designee thereof. The total number of shares of common stock reserved and available for issuance under the Plan on the Effective Date was 760,000.   The Company recorded $74,207 and $44,720 for the three months ended September 30, 2024 and 2023, respectively, and $218,136 and $126,428 for the nine months ended September 30, 2024 and 2023, respectively, of expense related to restricted stock awards in general and administrative expense in its consolidated statements of operations. As of September 30, 2024 and 2023, there was $400,266 and $232,262 of unrecognized compensation expense related to unvested time-based and performance-based restricted stock awards, respectively. That cost is expected to be recognized over a weighted-average period of 3.1 years and 2.6 years for time-based and performance-based awards, respectively. The fair value of common stock awards is determined based on the closing trading price of the common stock on the grant date. Forfeitures are accounted for as they occur, compensation cost previously recognized for an award that is forfeited because of a failure to satisfy a service or performance condition is reversed in the period of the forfeiture. Time-Based Restricted Stock Grants These time-based grants vest solely based on continued employment, with 6.25% of the shares eligible to vest on each three- month anniversary of the grant date during the remaining four-year time vesting period. Time-based restricted stock cannot be transferred during the vesting period. These time-based restricted stock grants entitle the holder to dividends paid by the Company on shares of its common stock, including unvested shares. A summary of the Company’s time-based restricted stock grant activity is as follows:             Weighted-Average             Grant-Date   Time-Based Restricted Stock Grants   Shares     Fair Value   Unvested at December 31, 2023     33,100     $ 4.84   Granted     91,544     $ 4.33   Vested     (31,828 )   $ 4.51   Forfeited     (1,530 )   $ 5.22   Unvested at September 30, 2024     91,286     $ 4.43       Performance-Based Restricted Stock Grants Performance-based restricted stock grants vest based on continued employment and the achievement of certain Funds from Operations, as adjusted (“AFFO”) and same store revenue growth (“SSRG”) goals by the Company during the year of the grant. Each of these performance components are weighted 50% and are measured over the performance cycle, which is defined as the year ending on December 31st in the year of the grant. At the end of the performance cycle, the financial performance components are reviewed to determine the number of shares actually earned, which can be as low as 0% of shares granted and up to a maximum of 200% of shares granted. The shares which are earned will remain subject to quarterly vesting during the remaining four-year time vesting period. Dividends paid by the Company prior to the determination of how many shares are earned will be retained by the Company and released only with respect to earned shares. If a Change in Control (as defined in the Plan) occurs the number of shares earned will equal the greater of the number of shares granted and the number of shares which would have been earned based on the AFFO and SSRG through the date of the Change in Control. If following a Change in Control, a grantee is terminated by the Company without Cause or by the grantee with Good Reason (as each is defined in the Plan), all unvested restricted stock will fully vest.   A summary of the Company’s performance-based restricted stock grant activity is as follows:             Weighted-Average             Grant-Date   Performance-Based Restricted Stock Grants   Shares     Fair Value   Unvested at December 31, 2023     40,024     $ 5.14   Granted     23,726     $ 4.32   Vested     (12,161 )   $ 5.08   Unvested at September 30, 2024     51,589     $ 4.78

Risks and Uncertainties [Abstract]
Risk and Uncertanties	14. RISKS AND UNCERTANTIES General Market Risks The Company’s operating activities are affected by global and national economic, political and market conditions generally and also by the local economic conditions where its assets are located. U.S. and international markets have experienced volatility in recent months and years due to a number of economic, political and global macro factors, including rising inflation, wars between Russia and Ukraine and in the Middle East, and the impact of the coronavirus (“COVID-19”) global pandemic. Uncertainties regarding the level and direction of central banks’ interest rate changes, political events, the Russia-Ukraine conflict and the Israel-Hamas conflict, trade tensions and the possibility of a national or global recession have also contributed to market volatility. The full impact of such external events on the financial and credit markets and consequently on the Company’s financial conditions and results of operations is uncertain and cannot be fully predicted. The Company will continue to monitor these events and will adjust its operations as necessary. Credit Risk Credit risk - Financial assets that are exposed to credit risk consist primarily of cash, cash equivalents, and restricted cash and certain portions of accounts receivable including rents receivable from our tenants. Risk to collection of rents receivable is mitigated by: (i) dispersion of rents receivable across many tenants, (ii) marketing targeted to tenants that have established credit, (iii) use of autopay, and (iv) use of collection procedures. Cash, cash equivalents and restricted cash are on deposit with highly rated commercial banks and financial institutions. Market Risk Investments in securities subject the Company to market risk. Investments in securities may decline in value. The Company monitors the stock prices of the investments and the financial performance of the related companies.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements of the Company are presented on the accrual basis of accounting in accordance with accounting standards generally accepted in the United States of America ("GAAP") for interim financial information, and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they may not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (including normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. The consolidated balance sheet as of December 31, 2023 has been derived from the Company’s audited financial statements as of that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2023.
Cash, Cash Equivalents, and Restricted Cash	Cash, Cash Equivalents, and Restricted Cash The Company’s cash is deposited with financial institutions located throughout the United States and at times may exceed federally insured limits. Cash equivalents may consist of money market fund shares and may include, among other things, highly liquid investments purchased with an original maturity of three months or less. Restricted cash is comprised of escrowed funds deposited with a bank relating to capital expenditures. The carrying amount reported on the balance sheet for cash, cash equivalents, and restricted cash approximates fair value. The following table provides a reconciliation of cash, cash equivalents, and restricted cash in our unaudited consolidated balance sheets to the total amount shown in our consolidated statements of cash flows:       September 30, 2024     December 31, 2023   Cash and cash equivalents   $ 6,762,074     $ 6,921,779   Restricted cash     165,060       106,767   Total cash, cash equivalents, and restricted cash as shown in our unaudited consolidated statements of cash flows   $ 6,927,134     $ 7,028,546
Income Taxes	Income Taxes The Company has elected to be treated as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). In order to maintain its qualification as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its stockholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax with respect to that portion of its income which meets certain criteria and is distributed annually to stockholders. The Company plans to continue to operate so that it meets the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. If the Company were to fail to meet these requirements, it would be subject to federal income tax. In management's opinion, the requirements to maintain these elections are being fulfilled. The Company is subject to certain state and local taxes. The Company has elected to treat its corporate subsidiary, SSG TRS LLC, as a taxable REIT subsidiary (“TRS”). In general, the Company’s TRS may perform additional services for tenants and may engage in any real estate or non-real estate related business. A TRS is subject to federal corporate income tax. The Company recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. The Company has reviewed its tax positions and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on federal, state, and local income tax returns for open tax years (2021 – 2023), or are expected to be taken in the Company’s 2024 tax returns.
Marketable Equity Securities	Marketable Equity Securities Investments in equity securities that have readily determinable fair values are measured at fair value. Gains or losses from changes in the fair value of equity securities are recorded in net income, until the investment is sold or otherwise disposed. The specific identification method is used to determine the realized gain or loss on investments sold or otherwise disposed. Fair value is determined using a valuation hierarchy generally by reference to an active trading market, using quoted closing or bid prices. Judgment is used to ascertain if a formerly active market has become inactive and in determining fair values when markets have become inactive.
Real Estate Assets	Real Estate Assets Real estate assets are carried at cost, less accumulated depreciation. Direct and allowable internal costs associated with the development, construction, renovation, and improvement of real estate assets are capitalized. Property taxes and other costs associated with development incurred during a construction period are capitalized. A construction period begins when expenditures for a real estate asset have been made and activities that are necessary to prepare the asset for its intended use are in progress. A construction period ends when an asset is substantially complete and ready for its intended use.   Acquisition costs are generally capitalized for acquisitions that qualify as asset acquisitions. When properties are acquired, the purchase price is allocated to the tangible and intangible assets acquired and liabilities assumed based on estimated fair values. Allocations to land, building and improvements, and equipment are recorded based upon their respective fair values as estimated by management. In allocating the purchase price for an acquisition, the Company determines whether the acquisition includes intangible assets or liabilities. The Company allocates a portion of the purchase price to an intangible asset attributed to the value of in-place leases. This intangible is generally amortized to expense over the expected remaining term of the respective leases. Substantially all of the leases in place at acquired properties are at market rates, as the majority of the leases are month-to-month contracts. Repairs and maintenance costs are charged to expense as incurred. Major replacements and betterments that improve or extend the life of the asset are capitalized and depreciated over their estimated useful lives. Depreciation is computed using the straight-line method over the estimated useful lives of the buildings and improvements, which are generally between 5 and 39 years.
Derivative Financial Instruments	Derivative Financial Instruments The Company carries all derivative financial instruments on the balance sheet at fair value. Fair value of derivatives is determined by reference to observable prices that are based on inputs not quoted on active markets, but corroborated by market data. The accounting for changes in the fair value of a derivative instrument depends on whether the derivative has been designated and qualifies as part of a hedging relationship. The Company’s use of derivative instruments has been limited to an interest rate cap agreement. For derivative instruments not designated as cash flow hedges, the unrealized gains and losses are included in interest expense in the accompanying statements of operations. For derivatives designated as cash flow hedges, the effective portion of the changes in the fair value of the derivatives is initially reported in accumulated other comprehensive income in the Company’s balance sheets and subsequently reclassified into earnings when the hedged transaction affects earnings. The valuation analysis of the interest rate cap reflects the contractual terms of derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves.
Accounts Payable and Accrued Expenses	Accounts Payable and Accrued Expenses Accounts payable and accrued expenses generally consist of property tax accruals, unearned rental income, and trade payables.
Revenue and Expense Recognition	Revenue and Expense Recognition Revenues from stores, which are primarily composed of rental income earned pursuant to month-to-month leases for storage space, as well as associated late charges and administrative fees, are recognized as earned in accordance with ASC Topic 842, Leases. Promotional discounts reduce rental income over the promotional period. Ancillary revenues from sales of merchandise and tenant insurance and other income are recognized as earned in accordance with ASC Topic 606, Revenue from Contracts with Customers ("ASC 606"). The Company's management fees are earned subject to the terms of the related property management services agreements (“PSAs”). These PSAs provide that the Company will perform management services, which include leasing and operating the property and providing accounting, marketing, banking, maintenance and other services. These services are provided in exchange for monthly management fees, which are based on a percentage of revenues collected from stores owned by third parties. PSAs generally have original terms of three years, after which management services are provided on a month-to-month basis unless terminated. Management fees are due on the last day of each calendar month that management services are provided. The Company accounts for the management services provided to a customer as a single performance obligation which are rendered over time each month in accordance with ASC 606. The total amount of consideration from the contract is variable as it is based on monthly revenues, which are influenced by multiple factors, some of which are outside the Company's control. No disaggregated information relating to PSAs is presented as the Company currently has only one contract. General and administrative expenses and property operations expenses, which may include among other expenses, property taxes, utilities, repairs and maintenance, and other expenses, are expensed as incurred. The Company accrues for property tax expense based upon actual amounts billed and, in some circumstances, estimates and historical trends when bills or assessments have not been received from the taxing authorities or such bills and assessments are in dispute.
Evaluation of Asset Impairment	Evaluation of Asset Impairment The Company evaluates its real estate assets and intangible assets, if any, for indicators of impairment. If there are indicators of impairment and we determine that the asset is not recoverable from future undiscounted cash flows to be received through the asset’s remaining life (or, if earlier, the expected disposal date), we record an impairment charge to the extent the carrying amount exceeds the asset’s estimated fair value or net proceeds from expected disposal. The Company evaluates goodwill for impairment annually and whenever relevant events, circumstances, and other related factors indicate that fair value may be less that carrying amounts. If it is determined that the carrying amount of goodwill exceeds the amount that would be allocated to goodwill if the reporting unit were acquired for estimated fair value, an impairment charge is recorded. There were no indicators of impairment to goodwill and real estate assets as of September 30, 2024, and no impairment charges were recorded for any periods presented herein.
Stock-based Compensation	Stock-based Compensation   The measurement and recognition of compensation expense for all stock-based compensation awards to employees and independent directors are based on estimated fair values. Awards granted are measured at fair value and any compensation expense is recognized over the service periods of each award. For awards granted which contain a graded vesting schedule and the only condition for vesting is a service condition, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For awards granted for which vesting is subject to a performance condition, compensation cost is recognized over the requisite service period if and when the Company concludes it is probable that the performance condition will be achieved. The estimated number of stock awards that will ultimately vest requires judgment, and to the extent actual results or updated estimates differ from our current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised.
Loan Procurement Costs	Loan Procurement Costs   Loan procurement costs on the Company's term loan note payable are presented as a direct deduction from the carrying amount of the related debt liability. The loan procurement costs related to the term loan note payable are amortized using the effective interest method over the life of the loan. Loan procurement costs associated with the Company's revolving line of credit remain in line of credit issuance costs, net of amortization on the Company's consolidated balance sheets. The costs related to the revolving line of credit are amortized using the straight-line method, which approximates the effective interest method, over the estimated life of the related debt.
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from management's estimates.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07 – Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amended guidance requires the disclosure of incremental segment information, including significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and a reconciliation of segment profit or loss to net income. The title and position of the CODM must also be disclosed, along with how the CODM uses the reported measures to assess segment performance and to allocate resources. Entities with a single reportable segment (such as the Company) will be required to provide the disclosures required by Topic 280, as amended. The standard became effective for the Company on January 1, 2024 and the required disclosures for the Company will begin with its Annual Report on Form 10-K for the fiscal year ending December 31, 2024. The adoption and implementation of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.
Credit Risk	Credit Risk Credit risk - Financial assets that are exposed to credit risk consist primarily of cash, cash equivalents, and restricted cash and certain portions of accounts receivable including rents receivable from our tenants. Risk to collection of rents receivable is mitigated by: (i) dispersion of rents receivable across many tenants, (ii) marketing targeted to tenants that have established credit, (iii) use of autopay, and (iv) use of collection procedures. Cash, cash equivalents and restricted cash are on deposit with highly rated commercial banks and financial institutions.
