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 condensed consolidated financial statements also include the accounts of (a) Murphy Canyon up until September 22, 2023, when it completed its business combination. Murphy Canyon was a special purpose acquisition company ("SPAC") for which we served as the financial sponsor (as described herein), and which was deemed to be controlled by us as a result of our 65% equity ownership stake, the overlap of three of our executive officers as executive officers of Murphy Canyon, and significant influence that we exercised over the funding and acquisition of new operations for an initial business combination (see Note 2, Variable Interest Entity). All intercompany balances, prior to deconsolidation and loss of control on September 22, 2023, have been eliminated in consolidation.

The Company classifies the noncontrolling interests in the NetREIT Partnerships as part of consolidated net (loss) income in 2024 and 2023 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 $1,200 in each period for the three months ended March 31, 2024 and for the three months ended March 31, 2023.

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 during each period for the three months ended March 31, 2024 and for the three months ended March 31, 2023.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash Equivalents and Restricted Cash. At March 31, 2024 and December 31, 2023, we had approximately $7.2 million and $6.5 million in cash, cash equivalents and restricted cash, respectively, of which approximately $3.1 million and $3.7 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, 2024 and December 31, 2023, the Company had approximately $1.8 million and $0.7 million, respectively, in deposits in financial institutions that exceeded the federally insurable limits. Restricted cash consists of funds held in escrow for Company lenders for properties held as collateral by the lenders. The funds in escrow are for payment of property taxes, insurance, leasing costs 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, 2024 and December 31, 2023, we have incurred approximately $21,750 and $5,000, respectively, in deferred offering costs as of the end of each period related to our registration statement on Form S-3.

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, 2024, we did not hold any marketable securities, excluding our investments in Conduit's common stock and common stock warrants. As of December 31, 2023, 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 $45,149, with a cost basis of approximately $40,315. Our investments in Conduit's common stock and common stock warrants 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 $14.5 million and $18.3 million as of March 31, 2024 and December 31, 2023, respectively, with a cost basis of approximately $7.5 million. The Company entered into a lock-up agreement with Conduit regarding certain of the common stock held by the Company, for 180 days from the closing of the business combination which ended March 20, 2024. There were no financial liabilities measured at fair value as of March 31, 2024 and December 31, 2023.

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.

The Company was involved in the formation of an entity considered to be a VIE, prior to September 22, 2023, when Murphy Canyon completed its business combination. The Company evaluated the consolidation of this entity as required pursuant to ASC Topic 810 relating to the consolidation of such VIE. The Company’s determination of whether it is the primary beneficiary of the VIE is based in part on an assessment of whether or not the Company and its related parties have the power to direct activities of the VIE and are exposed to the majority of the risks and rewards of the entity.

Following the completion of the Murphy Canyon IPO in January 2022, we determined that Murphy Canyon was a VIE in which we had a variable interest because we participated in its formation and design, manage the significant activities, and Murphy Canyon did not have enough equity at risk to finance its activities without additional subordinated financial support. We have also determined that Murphy Canyon's public stockholders did not have substantive rights, and their equity interest constituted temporary equity, outside of permanent equity, in accordance with ASC 480-10-S99-3A. As such, we have concluded that, prior to the business combination, we were the primary beneficiary of Murphy Canyon as a VIE, as we had the right to receive benefits or the obligation to absorb losses of the entity, as well as the power to direct a majority of the activities that significantly impacted Murphy Canyon's economic performance. Since we were the primary beneficiary, Murphy Canyon was consolidated into our condensed consolidated financial statements. See Note 9 Commitments and Contingencies for additional details regarding Murphy Canyon.
