(“Hartman XIX”) and Hartman vREIT XXI, Inc. (“vREIT XXI”) to form Hartman SPE, LLC ("SPE LLC"), a special purpose entity. On October 1, 2018, SPE LLC, as borrower, and Goldman Sachs Mortgage Company entered into a term loan agreement, pursuant to which the lender made a term loan to SPE LLC in the principal amount of $259,000,000. Contemporaneously therewith and together with our affiliates HIREIT, Hartman XIX and vREIT XXI, we contributed a total of 39 commercial real estate properties ("Properties") to SPE, LLC, subject to the then existing mortgage indebtedness encumbering the Properties, in exchange for membership interests in SPE LLC.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements as of December 31, 2020 and 2019 and for the years then ended have been prepared by the Company in accordance with accounting principles generally accepted in the United States and pursuant to the rules and regulations of the Securities and Exchange Commission, including Form 10-K and Regulation S-K. The information furnished herein reflects all adjustments (consisting of normal recurring accruals and adjustments), which are, in the opinion of management, necessary to fairly present the operating results for the respective periods. On May 14, 2020, the Merger Agreements were approved by the respective company shareholders. The accompanying consolidated financial statements reflect the financial condition and results of operations of the Company with an effective Mergers date of July 1, 2020. These consolidated financial statements include the accounts of the Company, the Operating Partnership and its subsidiaries, and SPE LLC. All significant intercompany balances and transactions have been eliminated. Revisions to Note 3 The Company made certain revisions to the disclosures in Note 3 – Restatement of Consolidated Financial Statements with respect to the impact of the previous restatement described in the Original Filing on historical quarterly financial information reported in 2020 and 2019. The Company has concluded that the revisions were not material. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures 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 differ from those estimates. Cash and Cash Equivalents Cash and cash equivalents on the accompanying consolidated balance sheets include all cash and liquid investments with maturities of three months or less. Cash and cash equivalents as of December 31, 2020 and 2019 consisted of demand deposits at commercial banks. We maintain accounts which may from time to time exceed federally insured limits. We have not experienced any losses in these accounts and believe that the company is not exposed to any significant credit risk and regularly monitors the financial stability of these financial institutions. As of December 31, 2020, the Company had a bank overdraft of $792,000. The overdraft is recorded as a liability in accounts payable and accrued expenses on the consolidated balance sheet. Restricted Cash Restricted cash on the accompanying consolidated balance sheets consists of amounts escrowed for future real estate taxes, insurance, capital expenditures and debt service, as required by certain of our mortgage debt agreements. As of December 31, 2020 and 2019, the Company had a restricted cash balance of $24,176,000 and $26,078,000, respectively. Financial Instruments The accompanying consolidated balance sheets include the following financial instruments: cash and cash equivalents, accrued rent and accounts receivable, accounts payable and accrued expenses and balances due to/ due from related parties, as well as related party notes receivable. The Company considers the carrying value of these financial instruments to approximate their respective fair values due to their short-term nature. Disclosure about the fair value of financial instruments is based on relevant information available as of December 31, 2020 and 2019. Revenue Recognition The Company's leases are accounted for as operating leases. Certain leases provide for tenant occupancy during perio ds for which no rent is due and/or for increases or decreases in the minimum lease payments over the terms of the leases. Revenue is recognized on a straight-line basis over the terms of the individual leases. Revenue recognition under a lease begins when the tenant takes possession of or controls the physical use of the leased space. When the Company acquires a property, the term of existing leases is considered to commence as of the acquisition date for the purposes of this calculation. The Company's accrued rents are included in accrued rent and accounts receivable, net. The Company defers the recognition of contingent rental income, such as percentage rents, until the specific target that triggers the contingent rental income is achieved. Cost recoveries from tenants are included in the tenant reimbursement and other revenues line item in the consolidated statements of operations in the period the related costs are incurred. As of January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-9, Revenue from Contracts with Customers, (“ASU 2014-9”) which amends the guidance for revenue recognition to eliminate the industry-specific revenue recognition guidance and replace it with a principle based approach for determining revenue recognition. The Company adopted ASU 2014-9 effective January 1, 2018 using the modified retrospective approach and the adoption of this guidance did not have a material impact on the consolidated financial statements. The Company’s revenue is primarily derived from leasing activities, which is specifically excluded from ASU 2014-9. The Company’s tenant reimbursements and other revenue is comprised of tenant reimbursements for real estate taxes, insurance, common area maintenance, and operating expenses. Reimbursements from real estate taxes and certain other expenses are also excluded from of ASU 2014-9. Additionally, the Company’s property dispositions have historically been cash sales with no contingencies and no future involvement in the property, as a result, the new guidance did not have an effect on the Company’s real estate transactions, however, the Company will account future sales of real estate properties in accordance with requirements of ASU 2014-9. Real Estate Allocation of Purchase Price of Acquired Assets Upon the acquisition of real properties, it is the Company’s policy to allocate the purchase price of properties to acquired tangible assets, consisting of land and buildings, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, other value of in-place leases and leasehold improvements and value of tenant relationships, based in each case on their fair values. The Company utilizes internal valuation methods to determine the fair values of the tangible assets of an acquired property (which includes land and buildings). The fair values of above-market and below-market in-place lease values, including below-market renewal options for which renewal has been determined to be reasonably assured, are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (a) the contractual amounts to be paid pursuant to the in-place leases and (b) an estimate of fair market lease rates for the corresponding in-place leases and below-market renewal options, which is generally obtained from independent appraisals, measured over a period equal to the remaining non-cancelable term of the lease. The above-market and below-market lease and renewal option values are capitalized as intangible lease assets or liabilities and amortized as an adjustment of rental revenue over the remaining expected terms of the respective leases. The fair values of in-place leases include direct costs associated with obtaining a new tenant, opportunity costs associated with lost rentals which are avoided by acquiring an in-place lease, and tenant relationships. Direct costs associated with obtaining a new tenant include commissions, tenant improvements, and other direct costs and are estimated based on independent appraisals and management’s consideration of current market costs to execute a similar lease. These direct costs are included in intangible lease assets and are amortized to expense over the remaining terms of the respective leases. The value of opportunity costs is calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. Customer relationships are valued based on expected renewal of a lease or the likelihood of obtaining a particular tenant for other locations. These intangibles are included in real estate assets in the consolidated balance sheets and are being amortized to expense over the remaining term of the respective leases. The determination of the fair values of the assets and liabilities acquired requires the use of significant assumptions with regard to the current market rental rates, rental growth rates, discount rates and other variables. The use of inappropriate estimates would result in an incorrect assessment of the purchase price allocations, which could impact the amount of the Company’s reported net income (loss). Real Estate Joint Ventures and Partnerships To determine the method of accounting for partially owned real estate joint ventures and partnerships, management determines whether an entity is a variable interest entity ("VIE") and, if so, determines which party is the primary beneficiary by analyzing whether we have both the power to direct the entity’s significant economic activities and the obligation to absorb potentially significant losses or receive potentially significant benefits. Significant judgments and assumptions inherent in this analysis include the design of the entity structure, the nature of the entity’s operations, future cash flow projections, the entity’s financing and capital structure, and contractual relationships and terms. We consolidate a VIE when we have determined that we are the primary beneficiary. Primary risks associated with our involvement with our VIEs include the potential funding of the entities’ debt obligations or making additional contributions to fund the entities’ operations or capital activities. Partially owned, non-variable interest real estate joint ventures and partnerships over which we have a controlling financial interest are consolidated in our consolidated financial statements. In determining if we have a controlling financial interest, we consider factors such as ownership interest, authority to make decisions, kick-out rights and substantive participating rights. Partially owned real estate joint ventures and partnerships where we do not have a controlling financial interest, but have the ability to exercise significant influence, are accounted for using the equity method. Management continually analyzes and assesses reconsideration events, including changes in the factors mentioned above, to determine if the consolidation or equity method treatment remains appropriate. Depreciation and amortization Depreciation is computed using the straight-line method over the estimated useful lives of 5 to 39 years for buildings and improvements. Tenant improvements are depreciated using the straight-line method over the lesser of the life of the improvement or the remaining term of the lease. In-place leases are amortized using the straight-line method over the weighted average years remaining calculated on terms of all of the leases in-place when acquired. Impairment The Company reviews its real estate assets for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations. The Company determines whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property. If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value. Projections of expected future cash flows require management to estimate future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, discount rates, the number of months it takes to release the property and the number of years the property is held for investment. The use of inappropriate assumptions in the future cash flow analysis would result in an incorrect assessment of the property’s future cash flow and fair value and could result in the overstatement of the carrying value of our real estate and related intangible assets and net income. During 2020, we identified the impact of the COVID-19 pandemic as an impairment trigger for properties occupied by certain tenants experiencing difficulties meeting their lease obligations to us. After considering the impacts of the COVID-19 pandemic on the key assumptions noted above, management has determined that the carrying values of 3 properties for the year ended December 31, 2020 were not recoverable. As a result, we recorded provisions for impairment of $5,406,000 for the year ended December 31, 2020 on the applicable properties impacted by the COVID-19 pandemic. Management determined that there was no impairment in the carrying value of the Company's real estate assets as of December 31, 2019. Fair Value Measurement Fair value measures are classified into a three-tiered fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1: Observable inputs such as quoted prices in active markets. Level 2: Directly or indirectly observable inputs, other than quoted prices in active markets. Level 3: Unobservable inputs in which there is little or no market data, which require a reporting entity to develop its own assumptions. Assets and liabilities measured at fair value are based on one or more of the following valuation techniques: Market approach: Prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Cost approach: Amount required to replace the service capacity of an asset (replacement cost). Income approach: Techniques used to convert future amounts to a single amount based on market expectations (including present-value, option-pricing, and excess-earnings models). The Company’s estimates of fair value were determined using available market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop estimated fair value. The use of different market assumptions or estimation methods may have a material effect on the estimated fair value amounts. The Company classifies assets and liabilities in the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. Recurring fair value measurements: The carrying values of cash and cash equivalents, restricted cash, accrued rent and accounts receivable, other assets and accounts payable and accrued expenses are reasonable estimates of fair values because of the short maturities of these instruments. For our disclosure of debt instrument fair value in Note 8, we use a discounted cash flow analysis based on borrowing rates currently available to the Company for loans with similar terms and maturities, discounting the future contractual interest and principal payments (categorized within Level 2 of the fair value hierarchy). Nonrecurring fair value measurements: Property Impairments The Company reviews its real estate assets for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations. Our estimated fair values are determined by utilizing cash flow models, market capitalization rates and market discount rates, or by obtaining third-party broker valuation estimates, or appraisals (categorized within Level 3 of the fair value hierarchy). Accrued Rent and Accounts Receivable, net Accrued rent and accounts receivable includes base rents, tenant reimbursements and receivables attributable to recording rents on a straight-line basis. An allowance for the uncollectible portion of accrued rent and accounts receivable is determined based upon customer credit-worthiness (including expected recovery of the Company’s claim with respect to any tenants in bankruptcy), historical bad debt levels, and current economic trends. Deferred Leasing Commissions Costs, net Leasing commissions are capitalized and amortized using the straight-line method over the term of the related lease agreements. Goodwill GAAP requires the Company to test goodwill for impairment at least annually or more frequently whenever events or circumstances occur indicating goodwill might be impaired. The Company applies a one-step quantitative assessment to determine if the estimated fair value is less than the carrying amount. If the carrying amount exceeds the estimated fair value, the Company will record a goodwill impairment equal to such excess, not to exceed the total amount of goodwill. No goodwill impairment has been recognized in the accompanying consolidated financial statements. Noncontrolling Interests Noncontrolling interests is the portion of equity in a subsidiary not attributable to a parent. The ownership interests not held by the parent are considered noncontrolling interests. Accordingly, the Company has reported noncontrolling interests in equity on the consolidated balance sheets but separate from the Company's equity. On the consolidated statements of operations, subsidiaries are reported at the consolidated amount, including both the amount attributable to the Company and noncontrolling interests. Stock-Based Compensation The Company follows Accounting Standards Codification ("ASC") 718- Compensation- Stock Compensation, with regard to issuance of stock in payment of services. ASC 718 requires that compensation cost relating to share-based payment transactions be recognized in the consolidated financial statements. The compensation cost is measured based on the estimated grant date fair value, as of the grant date of the Company’s common stock, of the equity or liability instruments issued. Stock-based compensation expense are recorded over the vesting period and is included in general and administrative expense in the accompanying consolidated statements of operations. Income Taxes The Company has elected to be treated as a REIT under the Internal Revenue Code of 1986, as amended, beginning with its taxable year ended December 31, 2011. To qualify as a REIT, the Company must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of the Company’s annual REIT taxable income to stockholders (which is computed without regard to the dividends-paid deduction or net capital gain and which does not necessarily equal net income as calculated in accordance with GAAP). As a REIT, the Company generally will not be subject to federal income tax on income that it distributes as dividends to its stockholders. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income tax on its taxable income at regular corporate income tax rates and generally will not be permitted to qualify for treatment as a REIT for federal income tax purposes for the four taxable years following the year during which qualification is lost, unless the Internal Revenue Service grants the Company relief under certain statutory provisions. Such an event could materially and adversely affect the Company’s net income and net cash available for distribution to stockholders. However, the Company believes that it is organized and will continue to operate in such a manner as to qualify for treatment as a REIT. For the years ended December 31, 2020 and 2019, the Company incurred a net loss of $11,010,000 and $4,610,000, as restated. The Company formed a taxable REIT subsidiary which may generate future taxable income which may be offset by the net loss carry forward. The Company considers that any deferred tax benefit and corresponding deferred tax asset which may be recorded in light of the net loss carry forward would be properly offset by an equal valuation allowance. Accordingly, no deferred tax benefit or deferred tax asset has been recorded in the consolidated financial statements. The Company is required to recognize in its consolidated financial statements the financial effects of a tax position only if it is determined that it is more likely than not that the tax position will not be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Management has reviewed the Company’s tax positions and is of the opinion that material positions taken by the Company would more likely than not be sustained upon examination. Accordingly, the Company has not recognized a liability related to uncertain tax positions. Loss Per Share The computations of basic and diluted loss per common share are based upon the weighted average number of common shares outstanding and potentially dilutive securities. The Company’s potentially dilutive securities include preferred shares that are convertible into the Company’s common stock. As of December 31, 2020 and 2019, there were no shares issuable in connection with these potentially dilutive securities. These potentially dilutive securities were excluded from the computations of diluted net loss per share for the years ended December 31, 2020 and 2019 because no shares are issuable and inclusion of such potentially dilutive securities would have been anti-dilutive. Concentration of Risk The geographic concentration of the Company’s real estate assets makes it susceptible to adverse economic developments in the State of Texas. Any adverse economic or real estate developments in these markets, such as business layoffs or downsizing, relocation of businesses, increased competition or any other changes, could adversely affect the Company’s operating results and its ability to make distributions to stockholders. Going Concern Evaluation Pursuant to ASU 2014-15, “Presentation of Financial Statements – Going Concern,” management is required to evaluate the Company’s ability to continue as a going concern within one year after the date that these consolidated financial statements are issued. The Hartman SPE LLC loan agreement (“SASB Loan”) has an initial maturity date of October 9, 2020. The SASB Loan provides for three successive one-year maturity date extensions. On October 9, 2020, SPE LLC executed a maturity date extension agreement to extend the maturity date to October 9, 2021. The SASB Loan requires that SPE LLC have a debt yield, as defined, greater than or equal to 12.50%. The first SASB Loan extension was completed on the basis that the debt yield as of June 30, 2020 was 13.25%. Debt yield is calculated by dividing annual net operating income by debt. The second one-year SASB Loan extension is within one year of the issuance of these consolidated financial statements. Uncertainty as to the debt yield calculation as of June 30, 2021 and the Company's ability to exercise the next remaining SASB Loan extension option, require management to conclude, in accordance with guidance provided by ASU 2014-15, that there is a substantial doubt about the Company's ability to continue as a going concern within one year of the issuance date of these consolidated financial statements solely on the basis of the uncertainty regarding the loan maturity extension of the SASB Loan. Management believes that SPE LLC will be able to extend the maturity date for the next one year period which will mitigate the maturity date issue. Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for in the same manner as operating leases today. As of December 31, 2020, the Company, through SPE LLC has a ground lease for a parking lot located adjacent to the property at 601 Sawyer, Houston, Texas. The parking lot lease agreement expires at the end of September 2025. The Sawyer property is included in the Company’s consolidated financial statements as of December 31, 2020 and 2019. Lease payments under the parking lot lease agreement are $3,500 per month through September 30, 2020 and $4,000 per month from October 1, 2020 through September 30, 2025. As of December 31, 2020, 57 monthly payments remain under the lease agreement for a total of $228,000. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. In connection with the new revenue guidance (ASC 606), the new revenue standard will apply to other components of revenue deemed to be non-lease components. Under the new guidance, we will continue to recognize the lease components of lease revenue on a straight-line basis over our respective lease terms as we do under prior guidance. However, we would recognize these non-lease components under the new revenue guidance as the related services are delivered. As a result, the total revenue recognized over time would not differ under the new guidance. This does not result in a difference from how the Company has historically recognized revenue for these lease and non-lease components. Additionally, ASU 2016-2 requires that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. Under ASU 2016-2, allocated payroll costs and other costs that are incurred regardless of whether the lease is obtained will no longer be capitalized as initial direct costs and instead will be expensed as incurred. This does not result in a difference from how the Company has historically recognized lease acquisition costs. On January 1, 2019, the Company adopted ASU 2018-07, "Improvements to Non-employee Stock-Based Payment Accounting." The updated guidance simplifies aspects of share-based compensation issued to non-employees by making the guidance consistent with the accounting for employee share-based compensation. The adoption of this guidance had no impact on our consolidated financial statements. On January 1, 2019, the Company adopted ASU 2017-12, "Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities". The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides companies with the option of either adopting the new standard early using a modified retrospective transition method in any interim period after issuance of the update, or alternatively adopting the new standard for fiscal years beginning after December 15, 2018. The adoption of this guidance had no impact on our consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instrument s — Credit Losses (Topic 326):Measurement of Credit Losses on Financial Instruments . The updated guidance requires measurement and recognition of expected credit losses for financial assets, including trade and other receivables, held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This is different from the current guidance as this will require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. Generally, the pronouncement requires a modified retrospective method of adoption. This guidance is effective for fiscal years and interim periods within those years beginning after January 2023, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on the consolidated financial statements when adopted. In March 2020, issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASU 2020-04 provides optional expedients for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The standard is effective for all entities as of March 12, 2020 through December 31, 2022. An entity can elect to apply the amendments as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to that date that the financial statements are available to be issued. The Company is currently evaluating the impact this guidance will have on the consolidated financial statements when adopted.

Restatement of Consolidated Fin

Restatement of Consolidated Financial Statements	12 Months Ended
	Dec. 31, 2020
Accounting Changes and Error Corrections [Abstract]
Restatement of Consolidated Financial Statements	Restatement of Consolidated Financial Statements Restatement reflected in Form 10-K/A In connection with the preparation of our consolidated quarterly financial statements as of and for the three months ended March 31, 2021, the Company identified a material error in our consolidated statement of cash flows for the year ended December 31, 2020. The restatement of our consolidated statement of cash flows for the year ended December 31, 2020 is necessary to reclassify $10,611,000 previously reported as net cash provided by operating activities, which should have been reported as net cash provided by financing activities. The correction changes the amount reported on the operating activities line item captioned "Due to/from related parties" and the financing activities line item captioned "Borrowings from an affiliate." The impact of the restatement on the quarterly consolidated financial statements for the quarterly period ended September 30, 2020 are as follows (in thousands): Nine Months ended September 30, 2020 As Previously Reported Restatement Adjustments As Restated Repayment of note receivable - related party $ 11,362 $ (10,611) $ 751 Net cash used in investing activities 2,902 (10,611) (7,709) Borrowing from an affiliate (1,611) 10,611 9,000 Net cash used in financing activities (19,058) 10,611 (8,447) Restatement background and explanation In connection with the preparation and audit of these consolidated financial statements, including matters related to the Mergers effective July 1, 2020, the Company has recorded several material adjustments to its financial statements as of December 31, 2020 including adjustments attributable to years ending December 31, 2019 and prior. For the year ended December 31, 2020, the Company recorded adjustments totaling $3,212,000 to correct the overstatement of accounts payable and accrued expenses prior to adjustment. The overstatement of accounts payable included (i) $1,112,000 attributable to the Three Forest property for improvements which were accrued for in 2016 and which should have been subsequently relieved as the property improvements were completed; (ii) $239,000 margin tax provision in excess of margin tax expense, and; (ii) $1,861,000 attributable to accounts payable which were not valid as of the end of December 31, 2019 together with accrued expense which should have been reversed as the invoices for which the expenses were accrued were paid. Impact of restatement on periods reported in 2020 The effect the restatement on quarterly consolidated financial statements for the quarterly periods ended March 31, 2020, June 30, 2020 and September 30, 2020 are as follows (in thousands): Consolidated Balance Sheet September 30, 2020 As Previously Reported Restatement Adjustments As Restated Accounts payable and accrued expenses $ 27,749 $ (2,100) $ 25,649 Total liabilities 336,663 (2,100) 334,563 Accumulated distributions and net loss (120,419) 2,100 (118,319) Total equity $ 201,052 $ 2,100 $ 203,152 Consolidated Statements of Operations Nine Months ended September 30, 2020 As Previously Reported Restatement Adjustments As Restated Property operating expenses $ 17,870 $ 868 $ 18,738 Depreciation and amortization 21,242 834 22,076 Total expenses 65,103 1,702 66,805 Net income (loss) 2,417 (1,702) 715 Net loss per share attributable to common shareholder $ 0.01 $ — $ (0.05) Weighted average of common shares outstanding, basic and diluted 29,168 — 29,168 Note there is no restatement to the consolidated statement of operations for the three months ended September 30, 2020.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Federal income taxes are not provided for because we qualify as a REIT under the provisions of the Internal Revenue Code and because we have distributed and intend to continue to distribute all of our taxable income to our stockholders. Our stockholders include their proportionate taxable income in their individual tax returns. As a REIT, we must distribute at least 90% of our real estate investment trust taxable income to our stockholders and meet certain income sources and investment restriction requirements. In addition, REITs are subject to a number of organizational and operational requirements. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax (including any applicable alternative minimum tax) on our taxable income at regular corporate tax rates. The Company’s federal income tax returns for the years ended December 31, 2015, 2016, 2017 and 2018 have not been examined by the Internal Revenue Service. The Company’s federal income tax return for the year ended December 31, 2015 may be examined on or before September 15, 2021. The Company has formed a taxable REIT subsidiary which may generate future taxable income which may be offset by the net loss carry forward. The Company considers that any deferred tax benefit and corresponding deferred tax asset which may be recorded in the light of the net loss carry forward would be properly offset by an equal valuation allowance. Accordingly, no deferred tax benefit or deferred tax asset has been recorded in the consolidated financial statements. The Company is required to recognize in its consolidated financial statements the financial effects of a tax position only if it is determined that it is more likely than not that the tax position will not be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Management has reviewed the Company’s tax positions and is of the opinion that material positions taken by the Company would more likely than not be sustained upon examination. Accordingly, the Company has not recognized a liability related to uncertain tax positions. Taxable income (loss) differs from net income (loss) for financial reporting purposes principally due to differences in the timing of recognition of interest, real estate taxes, depreciation and amortization and rental revenue. For Federal income tax purposes, the cash distributed to stockholders was characterized as follows for the years ended December 31: 2020 2019 Ordinary income (unaudited) 35.3 % 53.1 % Return of capital (unaudited) 64.7 % 46.9 % Capital gains distribution (unaudited) — % — % Total 100.0 % 100.0 % A provision for Texas Franchise tax under the Texas Margin Tax Bill in the amount of $192,000 and $385,000 was recorded in the consolidated financial statements for the years ended December 31, 2020 and 2019 respectively, with a corresponding charge to real estate taxes and insurance.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements as of December 31, 2020 and 2019 and for the years then ended have been prepared by the Company in accordance with accounting principles generally accepted in the United States and pursuant to the rules and regulations of the Securities and Exchange Commission, including Form 10-K and Regulation S-K. The information furnished herein reflects all adjustments (consisting of normal recurring accruals and adjustments), which are, in the opinion of management, necessary to fairly present the operating results for the respective periods. On May 14, 2020, the Merger Agreements were approved by the respective company shareholders. The accompanying consolidated financial statements reflect the financial condition and results of operations of the Company with an effective Mergers date of July 1, 2020.
Consolidation	These consolidated financial statements include the accounts of the Company, the Operating Partnership and its subsidiaries, and SPE LLC.  All significant intercompany balances and transactions have been eliminated.
Revisions to Note 3	Revisions to Note 3 The Company made certain revisions to the disclosures in Note 3 – Restatement of Consolidated Financial Statements with respect to the impact of the previous restatement described in the Original Filing on historical quarterly financial information reported in 2020 and 2019. The Company has concluded that the revisions were not material.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures 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 differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents on the accompanying consolidated balance sheets include all cash and liquid investments with maturities of three months or less. Cash and cash equivalents as of December 31, 2020 and 2019 consisted of demand deposits at commercial banks. We maintain accounts which may from time to time exceed federally insured limits. We have not experienced any losses in these accounts and believe that the company is not
Restricted Cash	Restricted Cash Restricted cash on the accompanying consolidated balance sheets consists of amounts escrowed for future real estate taxes, insurance, capital expenditures and debt service, as required by certain of our mortgage debt agreements. As of December 31, 2020 and 2019, the Company had a restricted cash balance of $24,176,000 and $26,078,000, respectively.
Financial Instruments	Financial Instruments The accompanying consolidated balance sheets include the following financial instruments: cash and cash equivalents, accrued rent and accounts receivable, accounts payable and accrued expenses and balances due to/ due from related parties, as well as related party notes receivable. The Company considers the carrying value of these financial instruments to approximate their respective fair values due to their short-term nature. Disclosure about the fair value of financial instruments is based on relevant information available as of December 31, 2020 and 2019.
Revenue Recognition	Revenue Recognition The Company's leases are accounted for as operating leases. Certain leases provide for tenant occupancy during perio ds for which no rent is due and/or for increases or decreases in the minimum lease payments over the terms of the leases. Revenue is recognized on a straight-line basis over the terms of the individual leases. Revenue recognition under a lease begins when the tenant takes possession of or controls the physical use of the leased space. When the Company acquires a property, the term of existing leases is considered to commence as of the acquisition date for the purposes of this calculation. The Company's accrued rents are included in accrued rent and accounts receivable, net. The Company defers the recognition of contingent rental income, such as percentage rents, until the specific target that triggers the contingent rental income is achieved. Cost recoveries from tenants are included in the tenant reimbursement and other revenues line item in the consolidated statements of operations in the period the related costs are incurred.
Real Estate	Real Estate Allocation of Purchase Price of Acquired Assets Upon the acquisition of real properties, it is the Company’s policy to allocate the purchase price of properties to acquired tangible assets, consisting of land and buildings, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, other value of in-place leases and leasehold improvements and value of tenant relationships, based in each case on their fair values. The Company utilizes internal valuation methods to determine the fair values of the tangible assets of an acquired property (which includes land and buildings). The fair values of above-market and below-market in-place lease values, including below-market renewal options for which renewal has been determined to be reasonably assured, are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (a) the contractual amounts to be paid pursuant to the in-place leases and (b) an estimate of fair market lease rates for the corresponding in-place leases and below-market renewal options, which is generally obtained from independent appraisals, measured over a period equal to the remaining non-cancelable term of the lease. The above-market and below-market lease and renewal option values are capitalized as intangible lease assets or liabilities and amortized as an adjustment of rental revenue over the remaining expected terms of the respective leases. The fair values of in-place leases include direct costs associated with obtaining a new tenant, opportunity costs associated with lost rentals which are avoided by acquiring an in-place lease, and tenant relationships. Direct costs associated with obtaining a new tenant include commissions, tenant improvements, and other direct costs and are estimated based on independent appraisals and management’s consideration of current market costs to execute a similar lease. These direct costs are included in intangible lease assets and are amortized to expense over the remaining terms of the respective leases. The value of opportunity costs is calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. Customer relationships are valued based on expected renewal of a lease or the likelihood of obtaining a particular tenant for other locations. These intangibles are included in real estate assets in the consolidated balance sheets and are being amortized to expense over the remaining term of the respective leases. The determination of the fair values of the assets and liabilities acquired requires the use of significant assumptions with regard to the current market rental rates, rental growth rates, discount rates and other variables. The use of inappropriate estimates would result in an incorrect assessment of the purchase price allocations, which could impact the amount of the Company’s reported net income (loss). Real Estate Joint Ventures and Partnerships To determine the method of accounting for partially owned real estate joint ventures and partnerships, management determines whether an entity is a variable interest entity ("VIE") and, if so, determines which party is the primary beneficiary by analyzing whether we have both the power to direct the entity’s significant economic activities and the obligation to absorb potentially significant losses or receive potentially significant benefits. Significant judgments and assumptions inherent in this analysis include the design of the entity structure, the nature of the entity’s operations, future cash flow projections, the entity’s financing and capital structure, and contractual relationships and terms. We consolidate a VIE when we have determined that we are the primary beneficiary. Primary risks associated with our involvement with our VIEs include the potential funding of the entities’ debt obligations or making additional contributions to fund the entities’ operations or capital activities. Partially owned, non-variable interest real estate joint ventures and partnerships over which we have a controlling financial interest are consolidated in our consolidated financial statements. In determining if we have a controlling financial interest, we consider factors such as ownership interest, authority to make decisions, kick-out rights and substantive participating rights. Partially owned real estate joint ventures and partnerships where we do not have a controlling financial interest, but have the ability to exercise significant influence, are accounted for using the equity method. Management continually analyzes and assesses reconsideration events, including changes in the factors mentioned above, to determine if the consolidation or equity method treatment remains appropriate. Depreciation and amortization Depreciation is computed using the straight-line method over the estimated useful lives of 5 to 39 years for buildings and improvements. Tenant improvements are depreciated using the straight-line method over the lesser of the life of the improvement or the remaining term of the lease. In-place leases are amortized using the straight-line method over the weighted average years remaining calculated on terms of all of the leases in-place when acquired. Impairment The Company reviews its real estate assets for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations. The Company determines whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property. If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value. Projections of expected future cash flows require management to estimate future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, discount rates, the number of months it takes to release the property and the number of years the property is held for investment. The use of inappropriate assumptions in the future cash flow analysis would result in an incorrect assessment of the property’s future cash flow and fair value and could result in the overstatement of the carrying value of our real estate and related intangible assets and net income. During 2020, we identified the impact of the COVID-19 pandemic as an impairment trigger for properties occupied by certain tenants experiencing difficulties meeting their lease obligations to us. After considering the impacts of the COVID-19 pandemic on the key assumptions noted above, management has determined that the carrying values of 3 properties for the year ended December 31, 2020 were not recoverable. As a result, we recorded provisions for impairment of $5,406,000 for the year ended December 31, 2020 on the applicable properties impacted by the COVID-19 pandemic. Management determined that there was no impairment in the carrying value of the Company's real estate assets as of December 31, 2019.
Fair Value Measurement	Fair Value Measurement Fair value measures are classified into a three-tiered fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1: Observable inputs such as quoted prices in active markets. Level 2: Directly or indirectly observable inputs, other than quoted prices in active markets. Level 3: Unobservable inputs in which there is little or no market data, which require a reporting entity to develop its own assumptions. Assets and liabilities measured at fair value are based on one or more of the following valuation techniques: Market approach: Prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Cost approach: Amount required to replace the service capacity of an asset (replacement cost). Income approach: Techniques used to convert future amounts to a single amount based on market expectations (including present-value, option-pricing, and excess-earnings models). The Company’s estimates of fair value were determined using available market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop estimated fair value. The use of different market assumptions or estimation methods may have a material effect on the estimated fair value amounts. The Company classifies assets and liabilities in the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. Recurring fair value measurements: The carrying values of cash and cash equivalents, restricted cash, accrued rent and accounts receivable, other assets and accounts payable and accrued expenses are reasonable estimates of fair values because of the short maturities of these instruments. For our disclosure of debt instrument fair value in Note 8, we use a discounted cash flow analysis based on borrowing rates currently available to the Company for loans with similar terms and maturities, discounting the future contractual interest and principal payments (categorized within Level 2 of the fair value hierarchy). Nonrecurring fair value measurements: Property Impairments The Company reviews its real estate assets for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations. Our estimated fair values are determined by utilizing cash flow models, market capitalization rates and market discount rates, or by obtaining third-party broker valuation estimates, or appraisals (categorized within Level 3 of the fair value hierarchy).
Accrued Rent and Accounts Receivables, net	Accrued Rent and Accounts Receivable, net Accrued rent and accounts receivable includes base rents, tenant reimbursements and receivables attributable to recording rents on a straight-line basis. An allowance for the uncollectible portion of accrued rent and accounts receivable is determined based upon customer credit-worthiness (including expected recovery of the Company’s claim with respect to any tenants in bankruptcy), historical bad debt levels, and current economic trends.
Deferred Leasing Commission Costs, net	Deferred Leasing Commissions Costs, net Leasing commissions are capitalized and amortized using the straight-line method over the term of the related lease agreements.
Goodwill	Goodwill GAAP requires the Company to test goodwill for impairment at least annually or more frequently whenever events or circumstances occur indicating goodwill might be impaired. The Company applies a one-step quantitative assessment to determine if the estimated fair value is less than the carrying amount. If the carrying amount exceeds the estimated fair value, the Company will record a goodwill impairment equal to such excess, not to exceed the total amount of goodwill. No goodwill impairment has been recognized in the accompanying consolidated financial statements.
Noncontrolling Interests	Noncontrolling InterestsNoncontrolling interests is the portion of equity in a subsidiary not attributable to a parent. The ownership interests not held by the parent are considered noncontrolling interests. Accordingly, the Company has reported noncontrolling interests in equity on the consolidated balance sheets but separate from the Company's equity. On the consolidated statements of operations, subsidiaries are reported at the consolidated amount, including both the amount attributable to the Company and noncontrolling interests.
Stock-Based Compensation	Stock-Based Compensation The Company follows Accounting Standards Codification ("ASC") 718- Compensation- Stock Compensation, with regard to issuance of stock in payment of services. ASC 718 requires that compensation cost relating to share-based payment transactions be recognized in the consolidated financial statements. The compensation cost is measured based on the estimated grant date fair value, as of the grant date of the Company’s common stock, of the equity or liability instruments issued. Stock-based compensation expense are recorded over the vesting period and is included in general and administrative expense in the accompanying consolidated statements of operations.
Income Taxes	Income Taxes The Company has elected to be treated as a REIT under the Internal Revenue Code of 1986, as amended, beginning with its taxable year ended December 31, 2011. To qualify as a REIT, the Company must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of the Company’s annual REIT taxable income to stockholders (which is computed without regard to the dividends-paid deduction or net capital gain and which does not necessarily equal net income as calculated in accordance with GAAP). As a REIT, the Company generally will not be subject to federal income tax on income that it distributes as dividends to its stockholders. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income tax on its taxable income at regular corporate income tax rates and generally will not be permitted to qualify for treatment as a REIT for federal income tax purposes for the four taxable years following the year during which qualification is lost, unless the Internal Revenue Service grants the Company relief under certain statutory provisions. Such an event could materially and adversely affect the Company’s net income and net cash available for distribution to stockholders. However, the Company believes that it is organized and will continue to operate in such a manner as to qualify for treatment as a REIT. For the years ended December 31, 2020 and 2019, the Company incurred a net loss of $11,010,000 and $4,610,000, as restated. The Company formed a taxable REIT subsidiary which may generate future taxable income which may be offset by the net loss carry forward. The Company considers that any deferred tax benefit and corresponding deferred tax asset which may be recorded in light of the net loss carry forward would be properly offset by an equal valuation allowance. Accordingly, no deferred tax benefit or deferred tax asset has been recorded in the consolidated financial statements. The Company is required to recognize in its consolidated financial statements the financial effects of a tax position only if it is determined that it is more likely than not that the tax position will not be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Management has reviewed the Company’s tax positions and is of the opinion that material positions taken by the Company would more likely than not be sustained upon examination. Accordingly, the Company has not recognized a liability related to uncertain tax positions.
Loss Per Share	Loss Per Share The computations of basic and diluted loss per common share are based upon the weighted average number of common shares outstanding and potentially dilutive securities. The Company’s potentially dilutive securities include preferred shares that are convertible into the Company’s common stock. As of December 31, 2020 and 2019, there were no shares issuable in connection with these potentially dilutive securities. These potentially dilutive securities were excluded from the computations of diluted net loss per share for the years ended December 31, 2020 and 2019 because no shares are issuable and inclusion of such potentially dilutive securities would have been anti-dilutive.
Concentration of Risk	Concentration of Risk The geographic concentration of the Company’s real estate assets makes it susceptible to adverse economic developments in the State of Texas. Any adverse economic or real estate developments in these markets, such as business layoffs or downsizing, relocation of businesses, increased competition or any other changes, could adversely affect the Company’s operating results and its ability to make distributions to stockholders.
Going Concern Evaluation	Going Concern Evaluation Pursuant to ASU 2014-15, “Presentation of Financial Statements – Going Concern,” management is required to evaluate the Company’s ability to continue as a going concern within one year after the date that these consolidated financial statements are issued. The Hartman SPE LLC loan agreement (“SASB Loan”) has an initial maturity date of October 9, 2020. The SASB Loan provides for three successive one-year maturity date extensions. On October 9, 2020, SPE LLC executed a maturity date extension agreement to extend the maturity date to October 9, 2021. The SASB Loan requires that SPE LLC have a debt yield, as defined, greater than or equal to 12.50%. The first SASB Loan extension was completed on the basis that the debt yield as of June 30, 2020 was 13.25%. Debt yield is calculated by dividing annual net operating income by debt. The second one-year SASB Loan extension is within one year of the issuance of these consolidated financial statements. Uncertainty as to the debt yield calculation as of June 30, 2021 and the Company's ability to exercise the next remaining SASB Loan extension option, require management to conclude, in accordance with guidance provided by ASU 2014-15, that there is a substantial doubt about the Company's ability to continue as a going concern within one year of the issuance date of these consolidated financial statements solely on the basis of the uncertainty regarding the loan maturity extension of the SASB Loan. Management believes that SPE LLC will be able to extend the maturity date for the next one year period which will mitigate the maturity date issue.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for in the same manner as operating leases today. As of December 31, 2020, the Company, through SPE LLC has a ground lease for a parking lot located adjacent to the property at 601 Sawyer, Houston, Texas. The parking lot lease agreement expires at the end of September 2025. The Sawyer property is included in the Company’s consolidated financial statements as of December 31, 2020 and 2019. Lease payments under the parking lot lease agreement are $3,500 per month through September 30, 2020 and $4,000 per month from October 1, 2020 through September 30, 2025. As of December 31, 2020, 57 monthly payments remain under the lease agreement for a total of $228,000. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. In connection with the new revenue guidance (ASC 606), the new revenue standard will apply to other components of revenue deemed to be non-lease components. Under the new guidance, we will continue to recognize the lease components of lease revenue on a straight-line basis over our respective lease terms as we do under prior guidance. However, we would recognize these non-lease components under the new revenue guidance as the related services are delivered. As a result, the total revenue recognized over time would not differ under the new guidance. This does not result in a difference from how the Company has historically recognized revenue for these lease and non-lease components. Additionally, ASU 2016-2 requires that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. Under ASU 2016-2, allocated payroll costs and other costs that are incurred regardless of whether the lease is obtained will no longer be capitalized as initial direct costs and instead will be expensed as incurred. This does not result in a difference from how the Company has historically recognized lease acquisition costs. On January 1, 2019, the Company adopted ASU 2018-07, "Improvements to Non-employee Stock-Based Payment Accounting." The updated guidance simplifies aspects of share-based compensation issued to non-employees by making the guidance consistent with the accounting for employee share-based compensation. The adoption of this guidance had no impact on our consolidated financial statements. On January 1, 2019, the Company adopted ASU 2017-12, "Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities". The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides companies with the option of either adopting the new standard early using a modified retrospective transition method in any interim period after issuance of the update, or alternatively adopting the new standard for fiscal years beginning after December 15, 2018. The adoption of this guidance had no impact on our consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instrument s — Credit Losses (Topic 326):Measurement of Credit Losses on Financial Instruments . The updated guidance requires measurement and recognition of expected credit losses for financial assets, including trade and other receivables, held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This is different from the current guidance as this will require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. Generally, the pronouncement requires a modified retrospective method of adoption. This guidance is effective for fiscal years and interim periods within those years beginning after January 2023, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on the consolidated financial statements when adopted. In March 2020, issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASU 2020-04 provides optional expedients for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The standard is effective for all entities as of March 12, 2020 through December 31, 2022. An entity can elect to apply the amendments as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to that date that the financial statements are available to be issued. The Company is currently evaluating the impact this guidance will have on the consolidated financial statements when adopted.
