Consolidation, Policy [Policy Text Block]

Principles of Consolidation. The accompanying consolidated financial statements include the accounts of Presidio Property Trust, Inc. and its subsidiaries, NetREIT Advisors, LLC and Dubose Advisors LLC (collectively, the “Advisors”), and NetREIT Dubose Model Home REIT, Inc. The consolidated financial statements also include the results of the NetREIT Partnerships and the Model Home Partnerships. As used herein, references to the “Company” include references to Presidio Property Trust, Inc., its subsidiaries, and the partnerships. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company classifies the noncontrolling interests in the NetREIT Partnerships as part of consolidated net (loss) income in 2025 and 2024 and has included the accumulated amount of noncontrolling interests as part of equity since inception in February 2010. If a change in ownership of a consolidated subsidiary results in loss of control and deconsolidation, any retained ownership interest will be remeasured, with the gain or loss reported in the consolidated statements of operations. Management has evaluated the noncontrolling interests and determined that they do not contain any redemption features.

Real Estate, Policy [Policy Text Block]

Real Estate Assets and Lease Intangibles. Land, buildings and improvements are recorded at cost, including tenant improvements and lease acquisition costs (including leasing commissions, space planning fees, and legal fees). The Company capitalizes any expenditure that replaces, improves, or otherwise extends the economic life of an asset, while ordinary repairs and maintenance are expensed as incurred. The Company allocates the purchase price of acquired properties between the acquired tangible assets and liabilities (consisting of land, buildings, tenant improvements, and long-term debt) and identified intangible assets and liabilities (including the value of above-market and below-market leases, the value of in-place leases, unamortized lease origination costs and tenant relationships), in each case based on their respective fair values.

The Company allocates the purchase price to tangible assets of an acquired property based on the estimated fair values of those tangible assets, assuming the property was vacant. Estimates of fair value for land, building and building improvements are based on many factors, including, but not limited to, comparisons to other properties sold in the same geographic area and independent third-party valuations. In estimating the fair values of the tangible assets, intangible assets, and liabilities acquired, the Company also considers information obtained about each property as a result of its pre‑acquisition due diligence, marketing and leasing activities.

The value allocated to acquired lease intangibles is based on management’s evaluation of the specific characteristics of each tenant’s lease. Characteristics considered by management in allocating these values include, but are not limited, to the nature and extent of the existing business relationships with the tenant, growth prospects for developing new business with the tenant, the remaining term of the lease, the tenant’s credit quality, and other factors.

The value attributable to the above-market or below-market component of an acquired in-place lease is determined based upon the present value (using a market discount rate) of the difference between (i) the contractual rents to be paid pursuant to the lease over its remaining term, and (ii) management’s estimate of rents that would be paid using fair market rates over the remaining term of the lease. The amounts allocated to above or below-market leases are amortized on a straight-line basis as an increase or reduction of rental income over the remaining non-cancelable term of the respective leases. Amortization of above and below-market rents resulted in a net increase in rental income of approximately $1,022 and $1,244 in each period for the three months ended March 31, 2025 and 2024.

The value of in-place leases and unamortized lease origination costs are amortized to expenses over the remaining term of the respective leases, which range from less than a year to ten years. The amount allocated to acquired in-place leases is determined based on management’s assessment of lost revenue and costs incurred for the period required to lease the “assumed vacant” property to the occupancy level when purchased.

The amount allocated to unamortized lease origination costs is determined by what the Company would have paid to a third-party to secure a new tenant reduced by the expired term of the respective lease. The amount allocated to tenant relationships is the benefit resulting from the likelihood of a tenant renewing its lease. Amortization expense related to these assets was approximately $4,382 and $4,382 during each period for the three months ended March 31, 2025 and 2024, respectively.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash, Cash Equivalents and Restricted Cash. At March 31, 2025 and December 31, 2024, we had approximately $12.0 million and $8.0 million in cash, cash equivalents and restricted cash, respectively, of which approximately $4.0 million and $5.0 million represented restricted cash, respectively. The Company considers all short-term, highly liquid investments that are both readily convertible to cash and have an original maturity of three months or less at the date of purchase to be cash equivalents. Items classified as cash equivalents include money market funds and short-term bonds. Cash balances in individual banks may exceed the federally insured limit of $250,000 by the Federal Deposit Insurance Corporation (the "FDIC"). No losses have been experienced related to such accounts. At March 31, 2025 and December 31, 2024, the Company had approximately $5.3 million and $1.0 million, respectively, in deposits in financial institutions that exceeded the federally insurable limits. Restricted cash consists of cash held in escrow by lenders pursuant to certain loan agreements, which are for payment of property taxes, insurance, leasing costs, future debt payments, and capital expenditures.

Deferred Charges, Policy [Policy Text Block]

Deferred Offering Costs. Deferred offering costs represent legal, accounting and other direct costs related to our offerings. As of March 31, 2025 and December 31, 2024, we have incurred approximately $60,000 and zero, respectively, in deferred offering costs.

Fair Value Measurement, Policy [Policy Text Block]

Fair Value Measurements. Certain assets and liabilities are required to be carried at fair value, or if long-lived assets are deemed to be impaired, to be adjusted to reflect this condition. The guidance requires disclosure of fair values calculated under each level of inputs within the following hierarchy:

•

Level 1: unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities;

•

Level 2: quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and

•

Level 3: prices or valuation techniques where little or no market data is available that requires inputs that are both significant to the fair value measurement and unobservable.

When available, we utilize quoted market prices from independent third-party sources to determine fair value and classify such items in Level 1 or Level 2. In instances where the market for a financial instrument is not active, regardless of the availability of a nonbinding quoted market price, observable inputs might not be relevant and could require us to make a significant adjustment to derive a fair value measurement.

Additionally, in an inactive market, a market price quoted from an independent third-party may rely more on models with inputs based on information available only to that independent third-party. When we determine the market for a financial instrument owned by us to be illiquid or when market transactions for similar instruments do not appear orderly, we use several valuation sources (including internal valuations, discounted cash flow analysis and quoted market prices) and establish a fair value by assigning weights to the various valuation sources. As of March 31, 2025, we did not hold any marketable securities, excluding our investments in Conduit's common stock and common stock warrants. As of December 31, 2024, our marketable securities (excluding our investments in Conduit's common stock and common stock warrants), held at a third party broker, presented on the consolidated balance sheets within other assets were measured at fair value using Level 1 market prices and totaled approximately zero, with a cost basis of approximately zero. There were no financial liabilities measured at fair value as of March 31, 2025 and December 31, 2024.

On April 22, 2024, the Company entered into a lockup agreement with Conduit pursuant to which the Company agreed not to transfer or sell 2,700,000 of its 4,015,250 shares of Conduit common stock for a period of one year. In consideration for entering into the lockup agreement, Conduit issued the Company a warrant ("Private CDT Warrants") to purchase 540,000 shares of common stock at an exercise price of $3.12 per share, with a two year term and exercisable one year after the date of issue. The Private CDT Warrants meet the ASC 321, Investments - Equity Securities ("ASC 321") scope exception for derivative instruments and are accounted for as a derivative under ASC 815, Derivatives and Hedging ("ASC 815"). As such, the Private CDT Warrants were recorded at fair value on the date of issuance and subsequently measured at fair value each period, with changes in fair value reported in gain or loss on Conduit Pharmaceuticals marketable securities. As of April 22, 2024, the Private CDT Warrants were valued at $891,000 based on a Level 3 fair value measurement, and subsequently adjusted to zero during the third quarter of 2024. As of March 31, 2025, the Private CDT Warrants fair value was still at zero, and is included in the total Investment in Conduit Pharmaceuticals marketable securities on the March 31, 2025 consolidated balance sheet. Our investments in Conduit's common stock (CDT) and public common stock warrants (CDTTW) presented on the consolidated balance sheets were measured at fair value using Level 1 market prices, taking into account the adoption of ASU 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, and totaled approximately $29,519 as of March 31, 2025. The combined value of our Investment in Conduit Pharmaceuticals marketable securities, including the Private CDT Warrants, totaled $29,519 as of March 31, 2025. Our investments in Conduit's common stock and public common stock warrants presented on the consolidated balance sheet were measured at fair value using Level 1 market prices as of December 31, 2024, and totaled approximately $0.2 million. The adjustments to the fair value of our investment in Conduit Pharmaceuticals marketable securities are recorded in net loss in Conduit Pharmaceuticals marketable securities on our consolidated statement of operations.

Consolidation, Variable Interest Entity, Policy [Policy Text Block]

Variable Interest Entity. We determine whether an entity is a Variable Interest Entity ("VIE") and, if so, whether it should be consolidated by utilizing judgments and estimates that are inherently subjective. Our determination of whether an entity in which we hold a direct or indirect variable interest is a VIE is based on several factors, including whether we participated in the design of the entity and the entity’s total equity investment at risk upon inception is sufficient to finance the entity’s activities without additional subordinated financial support. We make judgments regarding the sufficiency of the equity at risk based first on a qualitative analysis, and then a quantitative analysis, if necessary.

We analyze any investments in VIEs to determine if we are the primary beneficiary. In evaluating whether we are the primary beneficiary, we evaluate our direct and indirect economic interests in the entity. A reporting entity is determined to be the primary beneficiary if it holds a controlling financial interest in the VIE. Determining which reporting entity, if any, has a controlling financial interest in a VIE is primarily a qualitative approach focused on identifying which reporting entity has both: (i) the power to direct the activities of a VIE that most significantly impact such entity’s economic performance; and (ii) the obligation to absorb losses or the right to receive benefits from such entity that could potentially be significant to such entity. Performance of that analysis requires the exercise of judgment.

We consider a variety of factors in identifying the entity that holds the power to direct matters that most significantly impact the VIE’s economic performance, including, but not limited to, the ability to direct operating decisions and activities. In addition, we consider the rights of other investors to participate in those decisions. We determine whether we are the primary beneficiary of a VIE at the time we become involved with a variable interest entity and reconsider that conclusion continually. We consolidate any VIE of which we are the primary beneficiary.

Reclassification, Comparability Adjustment [Policy Text Block]

Reclassifications. Certain prior year balance sheet, statement of operations and statement of cash flows accounts have been reclassified to conform with the current year presentation. The reclassifications did not affect net income in the prior year's consolidated statement of operations.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Issued and Adopted Accounting Pronouncements. In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-09, Income Taxes, to enhance income tax disclosures, provide more information about tax risks and opportunities present in worldwide operations, and to disaggregate existing income tax disclosures. The guidance is effective for annual periods beginning after December 15, 2024 on a prospective basis, with the option to apply the standard retrospectively. Early adoption is permitted. We have adopted ASU 2023-09 and have updated our financial statement disclosures accordingly.

In November 2023, FASB issued Accounting Standards Update ASU 2023-07, Segment Reporting, establishing improvements to reportable segments disclosures to enhance segment reporting under Topic 280. This ASU aims to change how public entities identify and aggregate operating segments and apply quantitative thresholds to determine their reportable segments. This ASU also requires public entities that operate as a single reportable segment to provide all segment disclosures in Topic 280, not just entity level disclosures. The guidance will be effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024 and the amendments should be applied retrospectively to all periods presented in the financial statements. We have adopted ASU 2023-07 and have updated our segment financial statement disclosures accordingly.

In March 2024, the SEC issued final climate-disclosure rules to enhance and standardize climate‐related disclosures by public companies. With regards to financial statements, the rules requires disclosure of (i) capitalized costs, expenditures expensed, charges, and losses incurred as a result of severe weather events and other natural conditions, subject to applicable one percent and de minimis disclosure thresholds; (ii) capitalized costs, expenditures expensed, and losses related to carbon offsets and renewable energy credits or certificates (RECs) if used as a material component of a company's plans to achieve its disclosed climate-related targets or goals; and (iii) if the estimates and assumptions the company uses to produce the financial statements were materially impacted by risks and uncertainties associated with severe weather events and other natural conditions or any disclosed climate-related targets or transition plans, a qualitative description of how the development of such estimates and assumptions was impacted. The rules are effective for annual periods beginning January 1, 2025 and are to be applied prospectively. On April 4, 2024, the SEC voluntarily stayed the rules pending judicial review as a result of litigation.

In November 2024, FASB issued Accounting Standards Update ASU 2024-03, Income Statement—Reporting Comprehensive, Income—Expense Disaggregation Disclosures, Disaggregation of Income Statement Expenses (“ASU 2024-03”). This ASU is to improve the disclosures about a public business entity’s expenses and address requests from investors for more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation, amortization, and depletion) in commonly presented expense captions (such as cost of sales, SG&A, and research and development). The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. In January 2025, this was updated by ASU 2025-01—Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. The amendment in this Update amends the effective date of Update 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption of Update 2024-03 is permitted. We have not yet adopted ASU 2024-03 and are currently evaluating the impact on our financial statement disclosures.
