Summary of Significant Accounting Policies (Policies)	12 Months Ended
Dec. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements as of December 31, 2019 and 2018 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.
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.
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, 2019 and 2018 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.
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, 2019 and 2018, the Company had a restricted cash balance of $26,078,000 and $33,696,000, 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, 2019 and 2018.
Revenue Recognition	Revenue Recognition The Company's leases are accounted for as operating leases. Certain leases provide for tenant occupancy during periods 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 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	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 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 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. Management has determined that there has been no impairment in the carrying value of the Company’s real estate assets as of December 31, 2019 and 2018. 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.
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.
Accrued Rent and Accounts Receivables, net	Accrued Rent and Accounts Receivable, net Included in accrued rent and accounts receivable are 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, 2019 and 2018, the Company incurred a net loss of $5,995,000 and $3,540,000. 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, 2019 and 2018, 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, 2019 and 2018 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 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 (“SPE Loan”) has an initial maturity date of October 9, 2020. The SPE Loan provides for three successive one-year maturity date extensions. In order to exercise each successive one-year extension options, the Hartman SPE must meet five conditions in order to extend the maturity date without any further qualification. One of the five conditions is that Hartman SPE must have a debt yield, as defined, of 12.5% as of June 30, 2020. As of December 31, 2019 and March 31, 2020, Hartman SPE has a debt yield of 13.29% and 12.95%, respectively. In response to the coronavirus outbreak and related economic disruption, the Company has undertaken cost reduction and avoidance measures which began in March 2020. Management expects the test period debt calculation to be 12.5% or greater which will allow the Company to exercise the extension option based solely on the terms of the loan agreement. If the debt yield calculation as of the end of the June 30, 2020 test period is less than 12.5%, management believes that the lender will agree to a one-year extension, however, extension terms may be less favorable to the Company than as provided under the loan agreement. Any required modification of the loan agreement to conclude an extension of the maturity date may involve additional loan costs which would not otherwise be incurred. Management has concluded that there is 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 due to the fact of the uncertainty regarding the loan maturity of the SPE Loan. Management believes that Hartman SPE will be able to extend the maturity date for one year which will mitigate the maturity date issue within one year of the issuance date of these consolidated financial statements.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2016-2, Leases, along with various subsequent ASUs, 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 the previous guidance for operating leases today. The Company adopted ASU 2016-02 on January 1, 2019, using the modified retrospective transition method such that we applied the standard as of the adoption date. The Company adopted the new standard using the practical expedient package which allowed the Company, as both the lessor and lessee to 1) not reassess whether any expired or existing contracts are or contain leases; 2) not reassess the lease classification for any expired or existing leases; and 3) not reassess initial direct costs for any existing leases. As of December 31, 2019, 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 2020. The Sawyer property is included in the Company’s consolidated financial statements as of December 31, 2019 and for the year ended December 31, 2019 because of the consolidation of SPE with the Company. SPE commenced operations and is consolidated with the Company for periods beginning after September 30, 2018. Lease payments under the parking lot lease agreement are $3,500 per month. As of December 31, 2019, 9 monthly payments remain under the lease agreement for a total of $31,500. 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. On January 1, 2018, the Company adopted ASU 2014-9, codified in Accounting Standards Codification (“ASC”) 606 - “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-9 replaces most existing revenue recognition guidance under GAAP. The standard permits the use of either the retrospective or cumulative effect transition method. Certain contracts with customers, principally lease contracts, are not within the scope of the new guidance. The Company has elected to use the modified retrospective method. The adoption of ASU 2014-9 has no impact on the Company’s consolidated financial statements on adoption” at January 1, 2018. On January 1, 2018, the Company adopted ASU 2016-17, “Interest Held Through Related Parties That Are Under Common Control,” issued by the FASB, which amends the accounting guidance when determining the treatment of certain VIE’s to include the interest of related parties under common control in a VIE when considering whether or not the reporting entity is the primary beneficiary of the VIE when considering consolidation. In connection with our adoption of ASU 2016-17, we have determined that SPE LLC is a VIE and that the Company is the primary beneficiary. Accordingly, the accounts of SPE LLC are included in our consolidated financial position as of December 31, 2018 and beginning October 1, 2018, in our consolidated results of operations. The Company and its affiliates, Hartman XIX and HIREIT, are guarantors of the SPE LLC note payable. In June 2016, the FASB issued ASU 2016-13, 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 December 15, 2019, with early adoption permitted. In identifying all our financial instruments covered under this guidance, the majority of our instruments result from operating leasing transactions, which are not within the scope of the new standard and are to remain governed by the recently issued leasing guidance and other previously issued guidance. The adoption of this guidance had no impact on our consolidated financial statements.
Reclassification	Reclassification Certain items in the comparative consolidated financial statements have been reclassified to conform to the presentation adopted in the current period. Restricted cash reporting line was added on the face of the consolidated balance sheets. The balance currently reported as restricted cash was reported previously in the prepaid expenses and other assets. Additionally, insurance proceeds account has been reclassified from being reported in real estate taxes and insurance reporting line in 2018 to property operating expenses.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2019

The accompanying consolidated financial statements as of December 31, 2019 and 2018 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.

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.

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, 2019 and 2018 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.

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, 2019 and 2018, the Company had a restricted cash balance of $26,078,000 and $33,696,000, 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, 2019 and 2018.

Revenue Recognition

The Company's leases are accounted for as operating leases. Certain leases provide for tenant occupancy during periods 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 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 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 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. Management has determined that there has been no impairment in the carrying value of the Company’s real estate assets as of December 31, 2019 and 2018.

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.

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.

Accrued Rent and Accounts Receivables, net

Accrued Rent and Accounts Receivable, net

Included in accrued rent and accounts receivable are 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.

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 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

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, 2019 and 2018, the Company incurred a net loss of $5,995,000 and $3,540,000. 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, 2019 and 2018, 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, 2019 and 2018 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 (“SPE Loan”) has an initial maturity date of October 9, 2020. The SPE Loan provides for three successive one-year maturity date extensions. In order to exercise each successive one-year extension options, the Hartman SPE must meet five conditions in order to extend the maturity date without any further qualification. One of the five conditions is that Hartman SPE must have a debt yield, as defined, of 12.5% as of June 30, 2020.

As of December 31, 2019 and March 31, 2020, Hartman SPE has a debt yield of 13.29% and 12.95%, respectively. In response to the coronavirus outbreak and related economic disruption, the Company has undertaken cost reduction and avoidance measures which began in March 2020. Management expects the test period debt calculation to be 12.5% or greater which will allow the Company to exercise the extension option based solely on the terms of the loan agreement.

If the debt yield calculation as of the end of the June 30, 2020 test period is less than 12.5%, management believes that the lender will agree to a one-year extension, however, extension terms may be less favorable to the Company than as provided under the loan agreement. Any required modification of the loan agreement to conclude an extension of the maturity date may involve additional loan costs which would not otherwise be incurred.

Management has concluded that there is 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 due to the fact of the uncertainty regarding the loan maturity of the SPE Loan. Management believes that Hartman SPE will be able to extend the maturity date for one year which will mitigate the maturity date issue within one year of the issuance date of these consolidated financial statements.

Recently Adopted Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2016-2, Leases, along with various subsequent ASUs, 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 the previous guidance for operating leases today.

The Company adopted ASU 2016-02 on January 1, 2019, using the modified retrospective transition method such that we applied the standard as of the adoption date. The Company adopted the new standard using the practical expedient package which allowed the Company, as both the lessor and lessee to 1) not reassess whether any expired or existing contracts are or contain leases; 2) not reassess the lease classification for any expired or existing leases; and 3) not reassess initial direct costs for any existing leases.

As of December 31, 2019, 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 2020. The Sawyer property is included in the Company’s consolidated financial statements as of December 31, 2019 and for the year ended December 31, 2019 because of the consolidation of SPE with the Company. SPE commenced operations and is consolidated with the Company for periods beginning after September 30, 2018.

Lease payments under the parking lot lease agreement are $3,500 per month. As of December 31, 2019, 9 monthly payments remain under the lease agreement for a total of $31,500.

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.

On January 1, 2018, the Company adopted ASU 2014-9, codified in Accounting Standards Codification (“ASC”) 606 - “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-9 replaces most existing revenue recognition guidance under GAAP. The standard permits the use of either the retrospective or cumulative effect transition method. Certain contracts with customers, principally lease contracts, are not within the scope of the new guidance. The Company has elected to use the modified retrospective method. The adoption of ASU 2014-9 has no impact on the Company’s consolidated financial statements on adoption” at January 1, 2018.

On January 1, 2018, the Company adopted ASU 2016-17, “Interest Held Through Related Parties That Are Under Common Control,” issued by the FASB, which amends the accounting guidance when determining the treatment of certain VIE’s to include the interest of related parties under common control in a VIE when considering whether or not the reporting entity is the primary beneficiary of the VIE when considering consolidation. In connection with our adoption of ASU 2016-17, we have determined that SPE LLC is a VIE and that the Company is the primary beneficiary. Accordingly, the accounts of SPE LLC are included in our consolidated financial position as of December 31, 2018 and beginning October 1, 2018, in our consolidated results of operations. The Company and its affiliates, Hartman XIX and HIREIT, are guarantors of the SPE LLC note payable.

In June 2016, the FASB issued ASU 2016-13, 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 December 15, 2019, with early adoption permitted. In identifying all our financial instruments covered under this guidance, the majority of our instruments result from operating leasing transactions, which are not within the scope of the new standard and are to remain governed by the recently issued leasing guidance and other previously issued guidance. The adoption of this guidance had no impact on our consolidated financial statements.

Reclassification

Certain items in the comparative consolidated financial statements have been reclassified to conform to the presentation adopted in the current period. Restricted cash reporting line was added on the face of the consolidated balance sheets. The balance currently reported as restricted cash was reported previously in the prepaid expenses and

other assets. Additionally, insurance proceeds account has been reclassified from being reported in real estate taxes and insurance reporting line in 2018 to property operating expenses.
