Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Hartman vREIT XXI, Inc. (the “Company”) was formed on September 3, 2015 as a Maryland corporation. The Company elected to be treated as a real estate investment trust (“REIT”) beginning with its taxable year ended December 31, 2017. The Company’s fiscal year end is December 31. In its initial public offering (the “Offering”), the Company is offering to the public up to $250,000,000 in any combination of shares of Class A and Class T common stock and up to $19,000,000 in shares of Class A and Class T common stock to stockholders pursuant to its distribution reinvestment plan. Class A common stock is being offered to the public at an initial price of $10.00 per share and to stockholders at an initial price of $9.50 per share for Class A common stock purchased pursuant to the distribution reinvestment plan. Class T common stock is being offered to the public at an initial price of $9.60 per share and to stockholders at an initial price of $9.12 per share for Class T common stock purchased pursuant to the distribution reinvestment plan. The Company’s board of directors may, in its sole discretion and from time to time, change the price at which the Company offers shares to the public in the primary offering or pursuant to its distribution reinvestment plan to reflect changes in estimated value per share and other factors that the board of directors deems relevant. The Company’s advisor is Hartman XXI Advisors, LLC (the “Advisor”), a Texas limited liability company and wholly owned subsidiary of Hartman Advisors, LLC. Hartman Income REIT Management, Inc., an affiliate of the Advisor, is the Company’s sponsor and property manager (“Sponsor” and “Property Manager”). Subject to certain restrictions and limitations, the Advisor is responsible for managing the Company’s affairs on a day-to-day basis and for identifying and making acquisitions and investments on behalf of the Company. Substantially all the Company’s business is conducted through Hartman vREIT XXI Operating Partnership, L.P., a Texas limited partnership (the “OP”). The Company is the sole general partner of the OP. The initial limited partners of the OP are Hartman vREIT XXI Holdings LLC, a wholly owned subsidiary of the Company (“XXI Holdings”), and Hartman vREIT XXI SLP LLC (“SLP LLC”), a wholly owned subsidiary of Hartman Advisors, LLC. SLP LLC has invested $1,000 in the OP in exchange for a separate class of limited partnership interests (the “Special Limited Partnership Interests”). As the Company accepts subscriptions for shares, it will transfer substantially all the net proceeds of the Offering to the OP as a capital contribution. The partnership agreement provides that the OP will be operated in a manner that will enable the Company to (1) satisfy the requirements for being classified as a REIT for tax purposes, (2) avoid any federal income or excise tax liability and (3) ensure that the OP will not be classified as a “publicly traded partnership” for purposes of Section 7704 of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), which classification could result in the OP being taxed as a corporation, rather than as a partnership. In addition to the administrative and operating costs and expenses incurred by the OP in acquiring and operating real properties, the OP will pay all the Company’s administrative costs and expenses and such expenses will be treated as expenses of the OP. As of December 31, 2018, we had accepted subscriptions for, and issued 3,591,757 shares of our Class A common stock, including 142,561 shares issued as stock distributions and pursuant to our distribution reinvestment plan, and 129,668 shares of our Class T common stock in our initial public offering, including 7,595 shares issued as stock distributions and pursuant to our distribution reinvestment plan resulting in gross offering proceeds of $36,416,537.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements as of December 31, 2018 and 2017 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 financial position and operating results for the respective periods. The Company’s consolidated financial statements include the Company’s accounts and the accounts of the OP and XXI Holdings, the subsidiaries over which the Company has control. All intercompany balances and transactions are eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Reclassifications The Company has reclassified certain prior period amounts in the accompanying consolidated financial statements in order to be consistent with the current period presentation. These reclassifications had no effect on the previously reported working capital or results of operations. Cash and Cash Equivalents All highly liquid investments with original maturities of three months or less are considered to be cash equivalents. Cash and cash equivalents as of December 31, 2018 and 2017 consisted of demand deposits at commercial banks. 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, notes payable, net and due from (to) related parties. The Company considers the carrying value, other than notes payable, net, to approximate the fair value of these financial instruments based on the short duration between origination of the instruments and their expected realization. Based on borrowing rates currently available to the Company for loans with similar terms, the carrying value of its notes payable approximates fair value. Revenue Recognition 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. 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 consolidated statements of operations in the period the related costs are incurred. As of January 1, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers, (“ASU 2014-09”) 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 is not expected to have an effect on the Company’s real estate transactions, however, the Company will account for future sales of real estate properties in accordance with requirements of ASU 2014-09. Investment in Unconsolidated Entities The Company’s investment in Hartman Village Pointe was accounted for under the equity method at December 31, 2016. Effective February 8, 2017, the Company owns 100% of Hartman Village Pointe. On April 11, 2017, the Company entered into a membership interest purchase agreement with Hartman XX Operating Partnership (“XX OP”), the operating partnership of Hartman Short Term Income Properties XX, Inc., a related party, pursuant to which the Company may acquire up to $10,000,000 of XX OP’s equity ownership in Hartman Three Forest Plaza LLC. As of December 31, 2017, the Company has acquired an approximate 48.8% equity interest in Hartman Three Forest Plaza LLC for $8,700,000. On October 1, 2018, Hartman Three Forest Plaza LLC contributed the Three Forest Plaza property to Hartman SPE, LLC, a special purpose entity formed for the purpose of refinancing certain indebtedness of Hartman Short Term Income Properties XX, Inc., Hartman Short Term Income Properties XIX, Inc. and Hartman Income REIT, Inc. We received a 5.89% membership interest in Hartman SPE, LLC in exchange for our 48.8% minority interest in Three Forest Plaza LLC. Real Estate Allocation of Purchase Price of Acquired Assets Upon acquisition, the purchase price of properties is allocated to the tangible assets acquired, consisting of land, buildings and improvements, any assumed debt and asset retirement obligations, if any, based on their fair values. Acquisition costs, including acquisition fees paid to our advisor, are capitalized as part of the purchase price. Initial valuations are subject to change during the measurement period, but the measurement period ends as soon as the information is available. The measurement period shall not exceed one year from the acquisition date. Land and building and improvement fair values are derived based upon the Company’s estimate of fair value after giving effect to estimated replacement cost less depreciation or estimates of the relative fair value of these assets using discounted cash flow analyses or similar methods. Any difference between the fair value of the property acquired and the purchase price of the property is recorded as goodwill or gain (loss) on acquisition of the property. The Company determines the fair value of any assumed debt by calculating the net present value of the scheduled mortgage payments using interest rates for debt with similar terms and remaining maturities that the Company believes it could obtain at the date of acquisition. Any difference between the fair value and stated value of the assumed debt is recorded as a discount or premium and amortized over the remaining life of the loan as interest expense. In allocating the purchase price of each of the Company’s properties, the Company makes assumptions and uses various estimates, including, but not limited to, the estimated useful lives of the assets, the cost of replacing certain assets and discount rates used to determine present values. The Company uses Level 3 inputs to value acquired properties. Many of these estimates are obtained from independent third-party appraisals. However, the Company is responsible for the source and use of these estimates. These estimates require judgment and are subject to being imprecise; accordingly, if different estimates and assumptions were derived, the valuation of the various categories of the Company’s properties or related intangibles could in turn result in a difference in the depreciation or amortization expense recorded in the Company’s consolidated financial statements. These variances could be material to the Company’s results of operations and financial condition. Depreciation and amortization Depreciation is computed using the straight-line method over the estimated useful lives of 5 years to 39 years years for buildings and improvements. Acquired 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 calculated in terms of all of the leases in-place when acquired. Impairment The Company reviews its real estate and other 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 and other assets as of 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 re-lease 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 the Company’s 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. Organization and Offering Costs Prior to achieving the minimum offering amount of $1,000,000, organization and offering costs of the Company were incurred by Advisor on behalf of the Company. Such costs included legal, accounting, printing and other offering expenses, including marketing, salaries and direct expenses of the Advisor’s employees and employees of the Advisor’s affiliates and others. Under the terms of the advisory agreement between the Company and the Advisor, upon the satisfaction of the minimum offering amount and the release to the Company of all subscription proceeds held in escrow, the Company would be obligated to reimburse the Advisor for organization and offering costs incurred by Advisor in connection with the Offering. Effective December 31, 2016, the advisory agreement between the Company and the Advisor was amended to provide that the liability of the Company to the Advisor for reimbursement of offering and organization costs of the Company incurred by the Advisor prior to completion of the minimum offering, shall not be reimbursable to the Advisor until the Company’s receipt of gross offering proceeds in its initial public offering is $10,000,000. As of December 31, 2018, the Company has received $36,416,537 in gross offering proceeds. As of December 31, 2018, total organization and offering costs incurred for the offering amounted to $1,194,403 of which the Advisor has incurred organization and offering costs of $970,214 on behalf of the Company. The Advisor has been reimbursed $877,443 for organization and offering costs which is limited to the total organizational and offering costs incurred by the Company (including selling commissions, dealer manager fees and all other underwriting compensation) not exceeding 15% of the aggregate gross proceeds from the sale of the shares of common stock sold in the Offering. Organization costs, when recorded by the Company, are expensed as incurred, and offering costs, which include selling commissions, dealer manager fees and all other underwriting compensation, are deferred and charged to stockholders’ equity as such amounts are reimbursed or paid by the Advisor, the dealer manager or their affiliates from gross offering proceeds. For the years ended December 31, 2018 and 2017, such costs totaled $119,982 and $1,074,421, respectively. Stock-Based Compensation The Company follows Accounting Standard 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 fair value of the equity or liability instruments issued. Stock-based compensation is included in general and administrative expenses in the accompanying consolidated statements of operations. Income Taxes The Company elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code, commencing in the taxable year ended December 31, 2017. If the Company qualifies for taxation as a REIT, the Company generally will not be subject to federal corporate income tax to the extent it distributes its REIT taxable income to its stockholders, so long as it distributes at least 90 percent of its REIT taxable income (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.) REITs are subject to a number of other organizational and operational requirements. Even if the Company qualifies for taxation as a REIT, it may be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed income. Prior to qualifying to be taxed as a REIT, the Company is subject to normal federal and state corporation income taxes. The Company accounts for income taxes using the asset and liability method under which deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The Company records a valuation allowance for net deferred tax assets that are not expected to be realized. For the years ended December 31, 2018 and 2017, the Company incurred a net loss of $1,292,229 and $1,537,566, respectively. The Company does not anticipate forming any taxable REIT subsidiaries or otherwise generating 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 in that no future taxable income is expected. Accordingly, no deferred tax benefit or deferred tax asset has been recorded in the consolidated financial statements. 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 as of December 31, 2018 and 2017, respectively. On December 22, 2017, H.R. 1, known as the Tax Cuts and Jobs Act (the “TCJA”) was signed into law and included wide-scale changes to individual, pass-through and corporation tax laws, including those that impact the real estate industry, the ownership of real estate and real estate investments, and REITs. The Company has reviewed the provisions of the law that pertain to the Company and have determined them to have no material income tax effect for financial statement purposes for the year ended December 31, 2018. 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 special limited partnership interests that are convertible into the Company’s common stock. As of December 31, 2018 and 2017, 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, 2018 and 2017 because no shares were issuable and inclusion of such potentially dilutive securities would have been anti-dilutive. Concentration of Risk The Company maintains cash accounts in one U.S. financial institution. The terms of these deposits are on demand to minimize risk. The balances of these accounts may exceed the federally insured limits. No losses have been incurred in connection with these deposits. Recently Adopted Accounting Pronouncements On January 1, 2018, the Company adopted the new accounting standard 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. ASC 606 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 ASC 606 has no impact on the Company’s consolidated financial statements on adoption at January 1, 2018. On January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) No. 2016-01, Recognition and Measurement of Financial Assets and Liabilities, issued by the Financial Accounting Standards Board (“FASB”), which enhances the reporting requirements surrounding the measurement of financial instruments and requires equity securities to be measured at fair value with changes in the fair value recognized through net income for the period. The adoption of ASU No. 2016-01 has no material effect on our consolidated financial position or our consolidated results of operations. On January 1, 2018, the Company adopted ASU No. 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. Recent Accounting Pronouncements Not Yet Adopted In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for in the same manner as operating leases today. 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. In July 2018, the FASB issued ASU 2018-11, Targeted Improvements to Topic 842 Leases. The improvements in ASU 2018-11 provide for (a) an optional new transition method for adoption that results in initial recognition of a cumulative effect adjustment to retained earnings in the year of adoption and (b) a practical expedient for lessors, under certain circumstances, to combine the lease and non-lease components of revenues for presentation purposes. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, which clarifies, corrects, or consolidates authoritative guidance issued in ASU 2016-02 and is effective upon adoption of ASU 2016-02. In December 2018, the FASB issued ASU 2018-20, Leases (Topic 842): Narrow-Scope Improvements for Lessors, which requires lessors to exclude from variable payments, and therefore revenue, all lessor costs explicitly required to be paid by lessees directly to third parties. ASU 2018-20 also requires lessors to account for costs excluded from the consideration of a contract that are explicitly paid by the lessor and reimbursed by the lessee as variable payments. This will not result in a material impact, if any, to the historical financial statements. ASU No. 2016-02 is effective for reporting periods beginning January 1, 2019, with modified retrospective application for each reporting period presented at the time of adoption or utilizing the optional transition method under ASU 2018-11. Early adoption is also permitted for this guidance. The Company will adopt ASU 2016-02 using the modified retrospective approach that results in initial recognition of a cumulative effect adjustment to retained earnings in the year of adoption in accordance with ASU 2018-11. We expect to disclose in the 10-Q for the quarterly period ended March 31, 2019 that the adoption of ASU 2016-02 had no impact on the beginning cumulative accumulated distributions and net loss as of January 1, 2019. The Company is continuing to evaluate the disclosure requirements in Topic 842, Leases, and has not determined the impact on the footnote disclosures to its consolidated financial statements.

The Property Manager is a wholly owned subsidiary of Hartman Income REIT Management, LLC, which is wholly owned by Hartman Income REIT, Inc. and Subsidiaries of which approximately 16% of the voting stock is owned by Allen R. Hartman who is the Chief Executive Officer and Chairman of the Board of Directors. The Advisor and certain affiliates of the Advisor will receive fees and compensation in connection with the Offering, and the acquisition, management and sale of the Company’s real estate investments. In addition, in exchange for $1,000, the OP has issued the Advisor a separate, special limited partnership interest, in the form of Special Limited Partnership Interests. See Note 13 (“Special Limited Partnership Interest”) below. The Advisor will receive reimbursement for organizational and offering expenses incurred on the Company’s behalf, but only to the extent that such reimbursements do not exceed actual expenses incurred by the Advisor and would not cause the cumulative selling commission, the dealer manager fee and other organization and offering expenses borne by the Company to exceed 15.0% of gross offering proceeds from the sale of shares in the Offering. The Advisor, or its affiliates, will receive an acquisition fee equal to 2.5% of the cost of each investment the Company acquires, which includes the amount actually paid or allocated to fund the purchase, development, construction or improvement of each investment, including acquisition expenses and any debt attributable to each investment. The Advisor earned acquisition fees of $539,438 and $142,500, respectively, for the years ended December 31, 2018 and 2017. The Advisor, or its affiliates, will receive a debt financing fee equal to 1.0% of the amount available under any loan or line of credit originated or assumed, directly or indirectly, in connection with the acquisition, development, construction, improvement of properties or other permitted investments, which will be in addition to the acquisition fee paid to the Advisor. No debt financing fees were earned by Advisor for the years ended December 31, 2018 and 2017. The Company pays the Property Manager, an affiliate of the Advisor, property management fees equal to 3% of the effective gross revenues of the managed property. The Company pays and expects to pay the Property Manager leasing fees in an amount equal to the leasing fees charged by unaffiliated persons rendering comparable services in the same geographic location of the applicable property, provided that such fees will only be paid if a majority of the Company’s board of directors, including a majority of its independent directors, determines that such fees are fair and reasonable in relation to the services being performed. The Property Manager may subcontract the performance of its property management and leasing duties to third parties and the Property Manager will pay a portion of its property management fee to the third parties with whom it subcontracts for these services. The Company will reimburse the costs and expenses incurred by the Property Manager on the Company’s behalf, including the wages and salaries and other employee-related expenses of all employees of the Property Manager or its subcontractors who are engaged in the operation, management, maintenance or access control of our properties, including taxes, insurance and benefits relating to such employees, and travel and other out-of-pocket expenses that are directly related to the management of specific properties. Other charges, including fees and expenses of third-party professionals and consultants, will be reimbursed, subject to the limitations on fees and reimbursements contained in the Charter. If the Property Manager provides construction management services related to the improvement or finishing of tenant space in the Company’s real estate properties, the Company will pay the Property Manager a construction management fee in an amount that is usual and customary for comparable services rendered to similar projects in the geographic market of the project; provided, however, that the Company will only pay a construction management fee if a majority of the Company’s board of directors, including a majority of its independent directors, determines that such construction management fee is fair and reasonable and on terms and conditions not less favorable than those available from unaffiliated third parties. The Company will pay the Advisor a monthly asset management fee equal to one-twelfth of 0.75% of the higher of (i) the cost or (ii) the value of all real estate investments the Company acquires. If Advisor or affiliate provides a substantial amount of services, as determined by the Company’s independent directors, in connection with the sale of one or more assets, the Company will pay the Advisor a disposition fee equal to (1) in the case of the sale of real property, the lesser of: (A) one-half of the aggregate brokerage commission paid (including the disposition fee) or, if none is paid, the amount that customarily would be paid, or (B) 3% of the sales price of each property sold, and (2) in the case of the sale of any asset other than real property, 3% of the sales price of such asset. The Company will reimburse the Advisor for all expenses paid or incurred by the Advisor in connection with the services provided to the Company, subject to the limitation that, commencing four fiscal quarters after the Company’s acquisition of its first asset, the Company will not reimburse the Advisor for any amount by which its operating expenses (including the asset management fee) at the end of the four preceding fiscal quarters exceeds the greater of: (1) 2% of the Company’s average invested assets (as defined in the Charter), or (2) 25% of the Company’s net income determined without reduction for any additions to reserves for depreciation, bad debts or other similar non-cash reserves and excluding any gain from the sale of the Company’s assets for that period. Notwithstanding the above, the Company may reimburse the Advisor for expenses in excess of this limitation if a majority of the Company’s independent directors determines that such excess expenses are justified based on unusual and non-recurring factors. For the years ended December 31, 2018 and 2017, the Company incurred property management fees and reimbursable costs of $209,806 and $59,688 payable to the Property Manager and asset management fees of $84,721 and $50,231 payable to the Advisor. Property management fees and reimbursable costs paid to the Property Manager are included in property operating expenses in the accompanying consolidated statements of operations. Asset management fees paid to the Advisor are included in asset management fees in the accompanying consolidated statements of operations.

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesThe Company elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code, commencing in the taxable year ended December 31, 2017. If the Company qualifies for taxation as a REIT, the Company generally will not be subject to federal corporate income tax to the extent it distributes its REIT taxable income to its stockholders, so long as it distributes at least 90 percent of its REIT taxable income (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.) REITs are subject to a number of other organizational and operational requirements. Even if the Company qualifies for taxation as a REIT, it may be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed income. Prior to qualifying to be taxed as a REIT, the Company is subject to normal federal and state corporation income taxes. The Company accounts for income taxes using the asset and liability method under which deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The Company records a valuation allowance for net deferred tax assets that are not expected to be realized. For the years ended December 31, 2018 and 2017, the Company had net loss of $1,292,229 and $1,537,566, respectively. The Company does not anticipate forming any taxable REIT subsidiaries or otherwise generating 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 in that no future taxable income is expected. Accordingly, no deferred tax benefit or deferred tax asset has been recorded in the consolidated financial statements. 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 as of December 31, 2018 and 2017, respectively.

Common Stock Shares of Class A and Class T 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. Neither Class A or Class T common stock have any preferences or preemptive conversion or exchange rights. Preferred Stock The board of directors, with the approval of a majority of the entire board of directors and without any action by the stockholders, may amend the charter from time to time to increase or decrease the aggregate number of authorized shares of capital stock or the number of authorized shares of capital stock of any class or series. If the Company were to create and issue preferred stock or convertible stock with a distribution preference over common stock, payment of any distribution preferences of outstanding preferred stock or convertible stock would reduce the amount of funds available for the payment of distributions on our common stock. Further, holders of preferred stock are normally entitled to receive a preference payment in the event we liquidate, dissolve or wind up before any payment is made to our common stockholders, likely reducing the amount common stockholders would otherwise receive upon such an occurrence. In addition, under certain circumstances, the issuance of preferred stock or a separate class or series of common stock may render more difficult or tend to discourage a merger, tender offer or proxy contest, the assumption of control by a holder of a large block of our securities and the removal of incumbent management. Stock-Based Compensation The Company awards vested restricted common shares to non-employee directors as compensation in part for their service as members of the board of directors of the Company. These shares are fully vested when granted. These shares may not be sold while an independent director is serving on the board of directors. For the years ended December 31, 2018 and 2017 the Company granted 2,500 and 2,500 shares, respectively of restricted common stock to independent directors as compensation for services. The Company recognized $25,000 and $25,000 as stock-based compensation expense for the years ended December 31, 2018 and 2017, respectively, based upon the offering price of $10.00 per common share. Distributions The following table reflects the total distributions paid in cash and issued in shares of our common stock for the period from January 2017 (the month distributions were first paid) through December 31, 2018: Period Cash DRP & Stock Total First Quarter 2018 $ 153,832 $ 192,202 $ 346,034 Second Quarter 2018 182,226 245,363 427,589 Third Quarter 2018 215,317 293,079 508,396 Fourth Quarter 2018 236,895 344,918 581,813 Total $ 788,270 $ 1,075,562 $ 1,863,832 First Quarter 2017 $ 26,621 $ 19,340 $ 45,961 Second Quarter 2017 62,283 72,105 134,388 Third Quarter 2017 105,154 114,788 219,942 Fourth Quarter 2017 127,336 162,380 289,716 Total $ 321,394 $ 368,613 $ 690,007

Incentive Plans	Incentive PlansThe Company has adopted a long-term incentive plan (the “Incentive Award Plan”) that provides for the grant of equity awards to employees, directors and consultants and those of the Company’s affiliates. The Incentive Award Plan authorizes the granting of restricted stock, stock options, stock appreciation rights, restricted or deferred stock units, dividend equivalents, other stock-based awards and cash-based awards to directors, officers, employees and consultants of the Company and the Company’s affiliates’ selected by the board of directors for participation in the Incentive Award Plan. Stock options and shares of restricted common stock granted under the Incentive Award Plan will not, in the aggregate, exceed an amount equal to 5.0% of the outstanding shares of the Company’s common stock on the date of grant or award of any such stock options or shares of restricted stock. Stock options may not have an exercise price that is less than the fair market value of a share of the Company’s common stock on the date of grant.  Shares of common stock will be authorized and reserved for issuance under the Incentive Award Plan. The Company has adopted an independent directors’ compensation plan (the “Independent Directors Compensation Plan”) pursuant to which each of the Company’s independent directors will be entitled, subject to the plan’s conditions and restrictions, to receive an initial grant of 3,000 shares of restricted stock when the Company raises the minimum offering amount of $1,000,000 in the Offering.  Each new independent director that subsequently joins the Company’s board of directors will receive a grant of 3,000 shares of restricted stock upon his or her election to the Company’s board of directors. The shares of restricted common stock granted to independent directors fully vest upon the completion of the annual term for which the director was elected.  Subject to certain conditions, the non-vested shares of restricted stock granted pursuant to the Independent Directors Compensation Plan will become fully vested on the earlier to occur of (1) the termination of the independent director’s service as a director due to his or her death or disability, or (2) a change in control of the Company.  No awards have been granted under the Incentive Award Plan as of December 31, 2018.  Awards under the Independent Directors Compensation Plan for the years ended December 31, 2018 and 2017, respectively, consisted of 2,500 and 2,500 restricted, Class A common shares to our independent directors, valued at $10.00 per share based on the Offering price.  The stock-based compensation expense is included in general and administrative expense in the accompanying consolidated statements of operations.

Equity [Abstract]
Special Limited Partnership Interest	Special Limited Partnership InterestPursuant to the limited partnership agreement for the OP, SLP LLC, the holder of the Special Limited Partnership Interest, will be entitled to receive distributions equal to 15.0% of the OP’s net sales proceeds from the disposition of assets, but only after the Company’s stockholders have received, in the aggregate, cumulative distributions equal to their total invested capital plus a 6.0% cumulative, non-compounded annual pre-tax return on such aggregated invested capital. In addition, the holder or the Special Limited Partnership Interest is entitled to receive a payment upon the redemption of the Special Limited Partnership Interests. Pursuant to the limited partnership agreement for the OP, the Special Limited Partnership Interests will be redeemed upon: (1) the listing of the Company’s common stock on a national securities exchange; (2) the occurrence of certain events that result in the termination or non-renewal of the Company’s advisory agreement with the Advisor (“Advisory Agreement”) other than by the Company for “cause” (as defined in the Advisory Agreement); or (3) the termination of the Advisory Agreement by the Company for cause. In the event of the listing of the Company’s shares of common stock or a termination of the Advisory Agreement other than by the Company for cause, the Special Limited Partnership Interests will be redeemed for an aggregate amount equal to the amount that the holder of the Special Limited Partnership Interests would have been entitled to receive, as described above, if the OP had disposed of all of its assets at their fair market value and all liabilities of the OP had been satisfied in full according to their terms as of the date of the event triggering the redemption. Payment of the redemption price to the holder of the Special Limited Partnership Interests will be paid, at the holder’s discretion, in the form of (i) limited partnership interests in the OP, (ii) shares of the Company’s common stock, or (iii) a non-interest bearing promissory note. If the event triggering the redemption is a listing of the Company’s shares on a national securities exchange only, the fair market value of the assets of the OP will be calculated taking into account the average share price of the Company’s shares for a specified period. If the event triggering the redemption is an underwritten public offering of the Company’s shares, the fair market value will take into account the valuation of the shares as determined by the initial public offering price in such offering. If the triggering event of the redemption is the termination or non-renewal of the Advisory Agreement other than by the Company for cause for any other reason, the fair market value of the assets of the OP will be calculated based on an appraisal or valuation of the Company’s assets. In the event of the termination or non-renewal of the Advisory Agreement by the Company for cause, all of the Special Limited Partnership Interests will be redeemed by the OP for the aggregate price of $1.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements as of December 31, 2018 and 2017 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 financial position and operating results for the respective periods.
Consolidation	The Company’s consolidated financial statements include the Company’s accounts and the accounts of the OP and XXI Holdings, the subsidiaries over which the Company has control.  All intercompany balances and transactions are eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Reclassifications	Reclassifications The Company has reclassified certain prior period amounts in the accompanying consolidated financial statements in order to be consistent with the current period presentation. These reclassifications had no effect on the previously reported working capital or results of operations.
Cash and Cash Equivalents	Cash and Cash Equivalents All highly liquid investments with original maturities of three months or less are considered to be cash equivalents. Cash and cash equivalents as of December 31, 2018 and 2017 consisted of demand deposits at commercial banks.
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, notes payable, net and due from (to) related parties. The Company considers the carrying value, other than notes payable, net, to approximate the fair value of these financial instruments based on the short duration between origination of the instruments and their expected realization. Based on borrowing rates currently available to the Company for loans with similar terms, the carrying value of its notes payable approximates fair value.
Revenue Recognition	Revenue Recognition 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. 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 consolidated statements of operations in the period the related costs are incurred.
Investment in Unconsolidated Entities	Investment in Unconsolidated Entities The Company’s investment in Hartman Village Pointe was accounted for under the equity method at December 31, 2016. Effective February 8, 2017, the Company owns 100% of Hartman Village Pointe. On April 11, 2017, the Company entered into a membership interest purchase agreement with Hartman XX Operating Partnership (“XX OP”), the operating partnership of Hartman Short Term Income Properties XX, Inc., a related party, pursuant to which the Company may acquire up to $10,000,000 of XX OP’s equity ownership in Hartman Three Forest Plaza LLC. As of December 31, 2017, the Company has acquired an approximate 48.8% equity interest in Hartman Three Forest Plaza LLC for $8,700,000. On October 1, 2018, Hartman Three Forest Plaza LLC contributed the Three Forest Plaza property to Hartman SPE, LLC, a special purpose entity formed for the purpose of refinancing certain indebtedness of Hartman Short Term Income Properties XX, Inc., Hartman Short Term Income Properties XIX, Inc. and Hartman Income REIT, Inc. We received a 5.89% membership interest in Hartman SPE, LLC in exchange for our 48.8% minority interest in Three Forest Plaza LLC.
Real Estate	Real Estate Allocation of Purchase Price of Acquired Assets Upon acquisition, the purchase price of properties is allocated to the tangible assets acquired, consisting of land, buildings and improvements, any assumed debt and asset retirement obligations, if any, based on their fair values. Acquisition costs, including acquisition fees paid to our advisor, are capitalized as part of the purchase price. Initial valuations are subject to change during the measurement period, but the measurement period ends as soon as the information is available. The measurement period shall not exceed one year from the acquisition date. Land and building and improvement fair values are derived based upon the Company’s estimate of fair value after giving effect to estimated replacement cost less depreciation or estimates of the relative fair value of these assets using discounted cash flow analyses or similar methods. Any difference between the fair value of the property acquired and the purchase price of the property is recorded as goodwill or gain (loss) on acquisition of the property. The Company determines the fair value of any assumed debt by calculating the net present value of the scheduled mortgage payments using interest rates for debt with similar terms and remaining maturities that the Company believes it could obtain at the date of acquisition. Any difference between the fair value and stated value of the assumed debt is recorded as a discount or premium and amortized over the remaining life of the loan as interest expense. In allocating the purchase price of each of the Company’s properties, the Company makes assumptions and uses various estimates, including, but not limited to, the estimated useful lives of the assets, the cost of replacing certain assets and discount rates used to determine present values. The Company uses Level 3 inputs to value acquired properties. Many of these estimates are obtained from independent third-party appraisals. However, the Company is responsible for the source and use of these estimates. These estimates require judgment and are subject to being imprecise; accordingly, if different estimates and assumptions were derived, the valuation of the various categories of the Company’s properties or related intangibles could in turn result in a difference in the depreciation or amortization expense recorded in the Company’s consolidated financial statements. These variances could be material to the Company’s results of operations and financial condition. Depreciation and amortization Depreciation is computed using the straight-line method over the estimated useful lives of 5 years to 39 years years for buildings and improvements. Acquired 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 calculated in terms of all of the leases in-place when acquired. Impairment The Company reviews its real estate and other 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 and other assets as of December 31, 2018.
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.
Organization and Offering Costs	Organization and Offering Costs Prior to achieving the minimum offering amount of $1,000,000, organization and offering costs of the Company were incurred by Advisor on behalf of the Company. Such costs included legal, accounting, printing and other offering expenses, including marketing, salaries and direct expenses of the Advisor’s employees and employees of the Advisor’s affiliates and others. Under the terms of the advisory agreement between the Company and the Advisor, upon the satisfaction of the minimum offering amount and the release to the Company of all subscription proceeds held in escrow, the Company would be obligated to reimburse the Advisor for organization and offering costs incurred by Advisor in connection with the Offering. Effective December 31, 2016, the advisory agreement between the Company and the Advisor was amended to provide that the liability of the Company to the Advisor for reimbursement of offering and organization costs of the Company incurred by the Advisor prior to completion of the minimum offering, shall not be reimbursable to the Advisor until the Company’s receipt of gross offering proceeds in its initial public offering is $10,000,000. As of December 31, 2018, the Company has received $36,416,537 in gross offering proceeds. As of December 31, 2018, total organization and offering costs incurred for the offering amounted to $1,194,403 of which the Advisor has incurred organization and offering costs of $970,214 on behalf of the Company. The Advisor has been reimbursed $877,443 for organization and offering costs which is limited to the total organizational and offering costs incurred by the Company (including selling commissions, dealer manager fees and all other underwriting compensation) not exceeding 15% of the aggregate gross proceeds from the sale of the shares of common stock sold in the Offering. Organization costs, when recorded by the Company, are expensed as incurred, and offering costs, which include selling commissions, dealer manager fees and all other underwriting compensation, are deferred and charged to stockholders’ equity as such amounts are reimbursed or paid by the Advisor, the dealer manager or their affiliates from gross offering proceeds. For the years ended December 31, 2018 and 2017, such costs totaled $119,982 and $1,074,421, respectively.
Stock-Based Compensation	Stock-Based Compensation The Company follows Accounting Standard 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 fair value of the equity or liability instruments issued. Stock-based compensation is included in general and administrative expenses in the accompanying consolidated statements of operations.
Income Taxes	Income Taxes The Company elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code, commencing in the taxable year ended December 31, 2017. If the Company qualifies for taxation as a REIT, the Company generally will not be subject to federal corporate income tax to the extent it distributes its REIT taxable income to its stockholders, so long as it distributes at least 90 percent of its REIT taxable income (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.) REITs are subject to a number of other organizational and operational requirements. Even if the Company qualifies for taxation as a REIT, it may be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed income. Prior to qualifying to be taxed as a REIT, the Company is subject to normal federal and state corporation income taxes. The Company accounts for income taxes using the asset and liability method under which deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The Company records a valuation allowance for net deferred tax assets that are not expected to be realized. For the years ended December 31, 2018 and 2017, the Company incurred a net loss of $1,292,229 and $1,537,566, respectively. The Company does not anticipate forming any taxable REIT subsidiaries or otherwise generating 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 in that no future taxable income is expected. Accordingly, no deferred tax benefit or deferred tax asset has been recorded in the consolidated financial statements. 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 as of December 31, 2018 and 2017, respectively.
Loss Per Share	Loss Per Share
Recent Accounting Pronouncements / Recently Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements On January 1, 2018, the Company adopted the new accounting standard 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. ASC 606 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 ASC 606 has no impact on the Company’s consolidated financial statements on adoption at January 1, 2018. On January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) No. 2016-01, Recognition and Measurement of Financial Assets and Liabilities, issued by the Financial Accounting Standards Board (“FASB”), which enhances the reporting requirements surrounding the measurement of financial instruments and requires equity securities to be measured at fair value with changes in the fair value recognized through net income for the period. The adoption of ASU No. 2016-01 has no material effect on our consolidated financial position or our consolidated results of operations. On January 1, 2018, the Company adopted ASU No. 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. Recent Accounting Pronouncements Not Yet Adopted In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for in the same manner as operating leases today. 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. In July 2018, the FASB issued ASU 2018-11, Targeted Improvements to Topic 842 Leases. The improvements in ASU 2018-11 provide for (a) an optional new transition method for adoption that results in initial recognition of a cumulative effect adjustment to retained earnings in the year of adoption and (b) a practical expedient for lessors, under certain circumstances, to combine the lease and non-lease components of revenues for presentation purposes. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, which clarifies, corrects, or consolidates authoritative guidance issued in ASU 2016-02 and is effective upon adoption of ASU 2016-02. In December 2018, the FASB issued ASU 2018-20, Leases (Topic 842): Narrow-Scope Improvements for Lessors, which requires lessors to exclude from variable payments, and therefore revenue, all lessor costs explicitly required to be paid by lessees directly to third parties. ASU 2018-20 also requires lessors to account for costs excluded from the consideration of a contract that are explicitly paid by the lessor and reimbursed by the lessee as variable payments. This will not result in a material impact, if any, to the historical financial statements. ASU No. 2016-02 is effective for reporting periods beginning January 1, 2019, with modified retrospective application for each reporting period presented at the time of adoption or utilizing the optional transition method under ASU 2018-11. Early adoption is also permitted for this guidance. The Company will adopt ASU 2016-02 using the modified retrospective approach that results in initial recognition of a cumulative effect adjustment to retained earnings in the year of adoption in accordance with ASU 2018-11. We expect to disclose in the 10-Q for the quarterly period ended March 31, 2019 that the adoption of ASU 2016-02 had no impact on the beginning cumulative accumulated distributions and net loss as of January 1, 2019. The Company is continuing to evaluate the disclosure requirements in Topic 842, Leases, and has not determined the impact on the footnote disclosures to its consolidated financial statements.
