Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business	Organization and Business Hartman Short Term Income Properties XX, Inc. (the “Company”), is a Maryland corporation formed on February 5, 2009. The Company elected to be treated as a real estate investment trust (“REIT”) beginning with the taxable year ending December 31, 2011. As used herein, the “Company,” “we,” “us,” or “our”refer to Hartman Short Term Income Properties XX, Inc. and its consolidated subsidiaries, including the Operating Partnership, except where context otherwise requires. On July 19, 2018, we entered into a limited liability company agreement with our affiliates Hartman Income REIT, Inc. (“HIREIT”), Hartman Short Term Income Properties XIX, Inc. (“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. Proceeds of the Loan were immediately used to extinguish the existing mortgage indebtedness encumbering the Properties. Substantially all of our business is conducted through our wholly owned subsidiary, Hartman XX Limited Partnership, a Texas limited partnership (the “Operating Partnership”) and SPE LLC. Our wholly-owned subsidiary, Hartman XX REIT GP LLC, a Texas limited liability company, is the sole general partner of the Operating Partnership. We are the sole limited partner of the Operating Partnership. Our wholly-owned subsidiary, Hartman SPE Management, LLC ("SPE Management") is the manager of SPE LLC. Our single member interests in our limited liability company subsidiaries are owned by the Operating Partnership or its wholly owned subsidiaries. Subject to certain restrictions and limitations, Hartman Advisors LLC ("Advisor") is responsible for managing our affairs on a day-to-day basis and for identifying and making acquisitions and investments on our behalf pursuant to an advisory agreement (the “Advisory Agreement”) by and among the Company and Advisor. Management of the Company’s properties and the Properties, is provided pursuant to property management agreements with Hartman Income REIT Management, Inc.

On July 21, 2017, the Company and Hartman Short Term Income Properties XIX, Inc. (“Hartman XIX”), entered into an agreement and plan of merger (the “XIX Merger Agreement”). On July 21, 2017, as subsequently modified on May 8 2018, the Company, the Operating Partnership, Hartman Income REIT, Inc. (“HIREIT”) and Hartman Income REIT Operating Partnership LP, the operating partnership of HIREIT, (“HIROP”), entered into an agreement and plan of merger (the “HIREIT Merger Agreement,” and together with the XIX Merger Agreement, the “Merger Agreements”). Subject to the terms and conditions of the XIX Merger Agreement, including the satisfaction of all closing conditions set forth in the Merger Agreements, Hartman XIX will merge with and into the Company, with the Company surviving the merger (the “Hartman XIX Merger”). Subject to the terms and conditions of the HIREIT Merger Agreement, (i) HIREIT will merge with and into the Company, with HIREIT surviving the merger (the “HIREIT Merger,” and together with the Hartman XIX Merger, the “REIT Mergers”), and (ii) HIROP will merge and with and into the Operating Partnership, with the Operating Partnership surviving the merger (the “Partnership Merger,” and together with the REIT Mergers, the “Mergers”). The REIT Mergers are intended to qualify as a “reorganization” under, and within the meaning of, Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and the Partnership Merger is intended to be treated as a tax-deferred exchange under Section 721 of the Code. Subject to the terms and conditions of the XIX Merger Agreement, (i) each share of common stock of Hartman XIX (the “XIX Common Stock”) issued and outstanding immediately prior to the Effective Time (as defined in the XIX Merger Agreement) will be automatically cancelled and retired and converted into the right to receive 9,171.98 shares of common stock, $0.01 par value per share, of the Company (“Company Common Stock”), (ii) each share of 8% cumulative preferred stock of Hartman XIX issued and outstanding immediately prior to the Effective Time will be automatically cancelled and retired and converted into the right to receive 1.238477 shares of Company Common Stock, and (iii) each share of 9% cumulative preferred stock of Hartman XIX issued and outstanding immediately prior to the Effective Time will be automatically cancelled and retired and converted into the right to receive 1.238477 shares of Company Common Stock. Subject to the terms and conditions of the HIREIT Merger Agreement, (a) in connection with the HIREIT Merger, (i) each share of common stock of HIREIT (the “HIREIT Common Stock”) issued and outstanding immediately prior to the REIT Merger Effective Time (as defined in the HIREIT Merger Agreement) will be automatically cancelled and retired and converted into the right to receive 0.752222 shares of Company Common Stock, and (ii) each share of subordinate common stock of HIREIT will be automatically cancelled and retired and converted into the right to receive 0.863235 shares of Company Common Stock, and (b) in connection with the Partnership Merger, each unit of limited partnership interest in HIREIT Operating Partnership (“HIREIT OP Units”) issued and outstanding immediately prior to the Partnership Merger Effective Time (as defined in the HIREIT Merger Agreement) (other than any HIREIT OP Units held by HIREIT) will be automatically cancelled and retired and converted into the right to receive 0.752222 validly issued, fully paid and non-assessable units of limited partnership interests in XX Operating Partnership. Each Merger Agreement contains customary covenants, including covenants prohibiting HIREIT and Hartman XIX and their respective subsidiaries and representatives from soliciting, providing information or entering into discussions concerning proposals relating to alternative business combination transactions, subject to certain limited exceptions. The Merger Agreements may be terminated under certain circumstances, including but not limited to (i) by the mutual written consent of all the parties to a Merger Agreement, (ii) by either the Company or HIREIT or Hartman XIX, as applicable, if a final and non-appealable order is entered prohibiting or disapproving the applicable Mergers, (iii) by either the Company or HIREIT or Hartman XIX, as applicable, if the required approval of the applicable Mergers by the stockholders of the Company or HIREIT or Hartman XIX, as applicable (the “Stockholder Approvals”), have not been obtained, (iv) by either the Company or HIREIT or Hartman XIX, as applicable, upon a material uncured breach by the other party that would cause the closing conditions in the applicable Merger Agreement not to be satisfied, or (v) by either the Company or HIREIT or Hartman XIX, as applicable, if the applicable Mergers have not been completed on or before December 31, 2019. No termination fees or penalties are payable by any party to any Merger Agreement in the event of the termination of any Merger Agreement. The Merger Agreements contain certain representations and warranties made by the parties thereto. The representations and warranties of the parties were made solely for purposes of the contract among the parties, and are subject to certain important qualifications and limitations set forth in confidential disclosure letters delivered by the parties to the Mergers to the other parties to the Mergers. Moreover, certain of the representations and warranties are subject to a contractual standard of materiality that may be different from what may be viewed as material to stockholders, and the representations and warranties are primarily intended to establish circumstances in which either of the parties may not be obligated to consummate the Mergers, rather than establishing matters as facts. Each Merger Agreement sets forth certain conditions of the parties thereto to consummate the Mergers contemplated by such Merger Agreement, including (i) receipt of the applicable stockholder approvals, (ii) receipt of all regulatory approvals, (iii) the absence of any judgments, orders or laws prohibiting or restraining the consummation of the applicable Mergers, (iv) the effectiveness with the Securities and Exchange Commission (the “SEC”) of the registration statement on Form S-4 to be filed by the Company to register the shares of Company Common Stock to be issued as consideration in the REIT Mergers, (v) the delivery of certain documents, consents and legal opinions, and (vi) the truth and correctness of the representations and warranties of the respective parties, subject to the materiality standards contained in the Merger Agreements. In addition, the consummation of the HIREIT Merger and the Partnership Merger is a condition to the consummation of the Hartman XIX Merger, and vice versa. There can be no guarantee that the conditions to the closing of the Mergers set forth in the Merger Agreements will be satisfied.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements included in this report are unaudited; however, amounts presented in the consolidated balance sheet as of December 31, 2018 are derived from our audited consolidated financial statements as of that date. The unaudited consolidated financial statements as of June 30, 2019 have been prepared by the Company in accordance with accounting principles generally accepted in the United States (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission, including Form 10-Q and Regulation S-X, on a basis consistent with the annual audited consolidated financial statements. The consolidated financial statements presented herein reflect all adjustments (consisting of normal recurring accruals and adjustments), which are, in the opinion of management, necessary to fairly present the financial position of the Company as of June 30, 2019 , and the results of consolidated operations for the three and six months ended June 30, 2019 and 2018 , the consolidated statements of stockholders’ equity for the six months ended June 30, 2019 and 2018 and the consolidated statements of cash flows for the six months ended June 30, 2019 and 2018 . The results of the six months ended June 30, 2019 are not necessarily indicative of the results to be expected for the year ending December 31, 2019. The consolidated financial statements herein are condensed and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . These unaudited consolidated financial statements include the accounts of the Company, the Operating Partnership and its subsidiaries, and Hartman 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 June 30, 2019 and December 31, 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. 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 June 30, 2019 and December 31, 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 will defer the recognition of contingent rental income, such as percentage rents, until the specific target that triggers the contingent rental income is achieved. Additionally, cost recoveries from tenants are included in the Tenant Reimbursement and Other Revenues line item in the income statement in the period the related costs are incurred. As of January 1, 2018, the Company adopted Accounting Standards Update ("ASU") 2014-09, " Revenue from Contracts with Customers ," 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 2014-09 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 2014-09. 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 2014-09. 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 2014-09. 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 income 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 is no impairment indicated in the carrying value of our real estate assets as of June 30, 2019 and December 31, 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 Receivable 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 our claim with respect to any tenants in bankruptcy), historical bad debt levels, and current economic trends. Deferred Leasing Commission Costs Leasing commissions are 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 test 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. The consolidated statement of stockholders’ equity is included for financial statements, including beginning balances, activity for the period and ending balances for stockholders' equity, noncontrolling interests and total equity. 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 operate in such a manner as to qualify for treatment as a REIT. 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 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 accompanying 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. Income Per Share The computations of basic and diluted income 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 June 30, 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 income per share for the six months ended June 30, 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, relocations of businesses, increased competition or any other changes, could adversely affect the Company’s operating results and its ability to make distributions to stockholders. Recently Adopted Accounting Pronouncements On January 1, 2019, the Company adopted ASU 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 June 30, 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 June 30, 2019 and for the six months ended June 30, 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 June 30, 2019 , 15 monthly payments remain under the lease agreement for a total of $52,500 . 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, such as reimbursement for certain expenses which are based on usage. 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 2016-02 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 2016-02, 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. The Company is the lessor only under the parking lot lease described above. Application of the guidance will result in recording a right-of-use asset and lease liability of $52,500 for the parking lot ground lease for which it is the lessee and lease expense will be recognized on a straight-line basis. 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 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. Recent Accounting Pronouncements Not Yet Adopted 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. We are currently evaluating the impact this guidance will have on our consolidated financial statements when adopted.

Debt Disclosure [Abstract]
Notes Payable	Notes Payable The Operating Partnership is a party to four , cross-collateralized, term loan agreements with an insurance company. The term loans are secured by the Richardson Heights Property, the Cooper Street Property, the Bent Tree Green Property and the Mitchelldale Property. The loans require monthly payments of principal and interest due and payable on the first day of each month. Monthly payments are based on a 27 -year loan amortization. Each of the loan agreements are subject to customary covenants, representations and warranties which must be maintained during the term of the loan agreements. Each of the loan agreements provides for a fixed interest rate of 4.61% . As of June 30, 2019 , the Company was in compliance with all loan covenants, with respect to the loans above. Each of the loan agreements are secured by a deed of trust, assignment of licenses, permits and contracts, assignment and subordination of the management agreements and assignment of rents. The terms of the security instruments provide for the cross collateralization/cross default of the each of the loans. The outstanding balance of the four loans was $43,896,000 and $44,584,000 as of June 30, 2019 and December 31, 2018, respectively. On October 1, 2018, the Company through SPE LLC and Goldman Sachs Mortgage Company entered into a $259,000,000 term loan agreement. The Company together with its affiliates HIREIT, Hartman XIX and vREIT XXI, contributed a total of 39 commercial real estate properties ("Properties") to SPE, LLC, a recently formed Delaware limited liability company, subject to the mortgage indebtedness encumbering the Properties, in exchange for membership interests in SPE LLC. Proceeds of the Loan were immediately used to extinguish the existing mortgage indebtedness encumbering the Properties. The term of the loan is five years , comprised of an initial two -year term with three one -year extension options. Each extension option shall be subject to certain conditions precedent including (i) no default then outstanding, (ii) 30 days prior written notice, (iii) the properties must have a specified in-place net operating income debt yield and (iv) purchase of an interest rate cap as described below for the exercised option term or terms. The outstanding principal of the loan will bear interest at the one-month LIBOR rate plus 1.8% . As a condition to the funding of the Loan, SPE LLC has entered into an interest rate cap arrangement with SMBC Capital Markets, Inc. that caps LIBOR at 3.75% during the initial term of the Loan. The Loan Agreement contains various customary covenants, including but not limited to financial covenants, covenants requiring monthly deposits in respect of certain property costs, such as taxes, insurance, tenant improvements, and leasing commissions, covenants imposing restrictions on indebtedness and liens, and restrictions on investments and participation in other asset disposition, merger or business combination or dissolution transactions. The Loan Agreement is secured by, among other things, mortgages on the Properties.

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 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 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 accompanying 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.

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity Under the Company’s articles of incorporation, the Company has authority to issue 750,000,000 shares of common stock, $0.001 par value per share, and 200,000,000 shares of preferred stock, $0.001 par value per share. Common Stock Shares of common stock entitle the holders to one vote per share on all matters which stockholders are entitled to vote, to receive dividends and other distributions as authorized by the Company’s board of directors in accordance with the Maryland General Corporation Law and to all rights of a stockholder pursuant to the Maryland General Corporation Law. The common stock has no preferences or preemptive, conversion or exchange rights. Preferred Stock Under the Company’s articles of incorporation, the Company’s board of directors has the authority to issue one or more classes or series of preferred stock, and prior to the issuance of such stock, the board of directors has the power to classify or reclassify, in one or more series, any unissued shares and designate the preferences, rights and privileges of such shares. As of June 30, 2019 , and December 31, 2018 , respectively, the Company has issued 1,000 shares of convertible preferred stock to the Advisor at a price of $ 10.00 per share. Common Stock Issuable Upon Conversion of Convertible Preferred Stock The convertible preferred stock issued to the Advisor will convert to shares of the Company’s common stock if (1) the Company has made total distributions on then outstanding shares of the Company’s common stock equal to the issue price of those shares plus a 6 % cumulative, non-compounded, annual return on the issue price of those outstanding shares, (2) the Company lists its common stock for trading on a national securities exchange if the sum of prior distributions on then outstanding shares of the Company’s common stock plus the aggregate market value of the Company’s common stock (based on the 30-day average closing meets the same 6 % performance threshold, or (3) the Company’s advisory agreement with the Advisor expires without renewal or is terminated (other than because of a material breach by the Advisor), and at the time of such expiration or termination the Company is deemed to have met the foregoing 6 % performance threshold based on the Company’s enterprise value and prior distributions and, at or subsequent to the expiration or termination, the stockholders actually realize such level of performance upon listing or through total distributions. In general, the convertible stock will convert into shares of common stock with a value equal to 15 % of the excess of the Company’s enterprise value plus the aggregate value of distributions paid to date on then outstanding shares of common stock over the aggregate issue price of those outstanding shares plus a 6 % cumulative, non-compounded, annual return on the issue price of those outstanding shares.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements included in this report are unaudited; however, amounts presented in the consolidated balance sheet as of December 31, 2018 are derived from our audited consolidated financial statements as of that date. The unaudited consolidated financial statements as of June 30, 2019 have been prepared by the Company in accordance with accounting principles generally accepted in the United States (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission, including Form 10-Q and Regulation S-X, on a basis consistent with the annual audited consolidated financial statements. The consolidated financial statements presented herein reflect all adjustments (consisting of normal recurring accruals and adjustments), which are, in the opinion of management, necessary to fairly present the financial position of the Company as of June 30, 2019 , and the results of consolidated operations for the three and six months ended June 30, 2019 and 2018 , the consolidated statements of stockholders’ equity for the six months ended June 30, 2019 and 2018 and the consolidated statements of cash flows for the six months ended June 30, 2019 and 2018 . The results of the six months ended June 30, 2019 are not necessarily indicative of the results to be expected for the year ending December 31, 2019. The consolidated financial statements herein are condensed and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . These unaudited consolidated financial statements include the accounts of the Company, the Operating Partnership and its subsidiaries, and Hartman 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 June 30, 2019 and December 31, 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.
Financial Instruments	Financial Instruments
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 will defer the recognition of contingent rental income, such as percentage rents, until the specific target that triggers the contingent rental income is achieved. Additionally, cost recoveries from tenants are included in the Tenant Reimbursement and Other Revenues line item in the income statement in the period the related costs are incurred. As of January 1, 2018, the Company adopted Accounting Standards Update ("ASU") 2014-09, " Revenue from Contracts with Customers ," 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 2014-09 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 2014-09. 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 2014-09. 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 2014-09.
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 income 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 is no impairment indicated in the carrying value of our real estate assets as of June 30, 2019 and December 31, 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 Receivable	Accrued Rent and Accounts Receivable 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 our claim with respect to any tenants in bankruptcy), historical bad debt levels, and current economic trends.
Deferred Leasing Commission Costs	Deferred Leasing Commission Costs Leasing commissions are amortized using the straight-line method over the term of the related lease agreements.
Goodwill	Goodwill
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 operate in such a manner as to qualify for treatment as a REIT. 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 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 accompanying 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.
Income Per Share	Income Per Share The computations of basic and diluted income 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 June 30, 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 income per share for the six months ended June 30, 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, relocations of businesses, increased competition or any other changes, could adversely affect the Company’s operating results and its ability to make distributions to stockholders.
Recently Adopted and Not Yet Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements On January 1, 2019, the Company adopted ASU 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 June 30, 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 June 30, 2019 and for the six months ended June 30, 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 June 30, 2019 , 15 monthly payments remain under the lease agreement for a total of $52,500 . 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, such as reimbursement for certain expenses which are based on usage. 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 2016-02 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 2016-02, 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. The Company is the lessor only under the parking lot lease described above. Application of the guidance will result in recording a right-of-use asset and lease liability of $52,500 for the parking lot ground lease for which it is the lessee and lease expense will be recognized on a straight-line basis. 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 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. Recent Accounting Pronouncements Not Yet Adopted 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. We are currently evaluating the impact this guidance will have on our consolidated financial statements when adopted.
