Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Griffin Realty Trust, Inc. (formerly known as Griffin Capital Essential Asset REIT, Inc.) (“GRT” or the “Company”) is an internally managed, publicly registered non-traded real estate investment trust ("REIT") that owns and operates a geographically diversified portfolio of corporate office and industrial properties that are primarily net-leased. GRT’s year-end date is December 31. On December 14, 2018, GRT, Griffin Capital Essential Asset Operating Partnership II, L.P. (the “GCEAR II Operating Partnership”), GRT’s wholly-owned subsidiary Globe Merger Sub, LLC (“EA Merger Sub”), the entity formerly known as Griffin Capital Essential Asset REIT, Inc. (“EA-1”), and GRT OP, L.P. (formerly known as Griffin Capital Essential Asset Operating Partnership, L.P.) (the “GRT OP”) entered into an Agreement and Plan of Merger (the “EA Merger Agreement”). On April 30, 2019, pursuant to the EA Merger Agreement, (i) EA-1 merged with and into EA Merger Sub, with EA Merger Sub surviving as GRT’s direct, wholly-owned subsidiary (the “EA Company Merger”) and (ii) the GCEAR II Operating Partnership merged with and into the GRT OP (the “EA Partnership Merger” and, together with the EA Company Merger, the “EA Mergers”), with the GRT OP surviving the EA Partnership Merger. In addition, on April 30, 2019, following the EA Mergers, EA Merger Sub merged into GRT. On March 1, 2021, the Company completed its previously announced acquisition of Cole Office & Industrial REIT (CCIT II), Inc. (“CCIT II”) for approximately $1.3 billion, including transaction costs, in a stock-for-stock transaction (the “CCIT II Merger”). At the effective time of the CCIT II Merger, each issued and outstanding share of CCIT II Class A common stock and each issued and outstanding share of CCIT II Class T common stock was converted into the right to receive 1.392 shares of the Company's Class E common stock. On July 1, 2021, the Company changed its name from Griffin Capital Essential Asset REIT, Inc. to Griffin Realty Trust, Inc. and the GRT OP changed its name from Griffin Capital Essential Asset Operating Partnership, L.P. to GRT OP, L.P. The GRT OP owns, directly or indirectly, all of the properties that the Company has acquired. As of June 30, 2021, (i) the Company owned approximately 91.0% of the outstanding common limited partnership units of the GRT OP ("GRT OP Units"), (ii), the former sponsor and certain of its affiliates owned approximately 7.8% of the limited partnership units of the GRT OP, including approximately 2.4 million units owned by the Company’s Executive Chairman and Chairman of the Company's Board of Directors (the "Board"), Kevin A. Shields, a result of the contribution of five properties to the Company and the self-administration transaction, and (iii) the remaining approximately 1.2% GRT OP Units are owned by unaffiliated third parties. The GRT OP may conduct certain activities through one or more of the Company’s taxable REIT subsidiaries, which are wholly-owned subsidiaries of the GRT OP.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies There have been no significant changes to the Company’s accounting policies since the Company filed its audited financial statements in its Annual Report on Form 10-K for the year ended December 31, 2020. For further information about the Company’s accounting policies, refer to the Company’s consolidated financial statements and notes thereto for the year ended included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC"). The accompanying unaudited consolidated financial statements of the Company are prepared by management on the accrual basis of accounting and in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information as contained in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), and in conjunction with rules and regulations of the SEC. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. The unaudited consolidated financial statements include accounts and related adjustments, which are, in the opinion of management, of a normal recurring nature and necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the interim period. Operating results for the six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. These unaudited consolidated financial statements 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, 2020 . In addition, see the risk factors identified in the “Risk Factors” section of the Company's Annual Report on Form 10-K for the year ended December 31, 2020. The consolidated financial statements of the Company include all accounts of the Company, the GRT OP, and its subsidiaries. Intercompany transactions are not shown on the consolidated statements. However, each property-owning entity is a wholly-owned subsidiary which is a special purpose entity ("SPE"), whose assets and credit are not available to satisfy the debts or obligations of any other entity, except to the extent required with respect to any co-borrower or guarantor under the same credit facility. Use of Estimates The preparation of the unaudited consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates. Change in Consolidated Financial Statements Presentation Certain amounts in the Company's prior period consolidated financial statements have been reclassified to conform to the current period presentation. Investment in unconsolidated entities has been reclassified to other assets on the Company's consolidated balance sheets all periods presented. Per Share Data The Company reports earnings per share for the period as (1) basic earnings per share computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding during the period, and (2) diluted earnings per share computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding, including common stock equivalents. As of June 30, 2021 and December 31, 2020, there were no material common stock equivalents that would have a dilutive effect on earnings (loss) per share for common stockholders. Segment Information ASC 280, Segment Reporting, establishes standards for reporting financial and descriptive information about a public entity’s reportable segments. The Company internally evaluates all of the properties and interests therein as one reportable segment. Income Taxes The Company has elected to be taxed as a REIT under the Internal Revenue Code ("Code"). To qualify as a REIT, the Company must meet certain organizational and operational requirements. The Company intends to adhere to these requirements and maintain its REIT status for the current year and subsequent years. As a REIT, the Company generally will not be subject to federal income taxes on taxable income that is distributed to stockholders. However, the Company may be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed taxable income, if any. If the Company fails to qualify as a REIT in any taxable year, the Company will then be subject to federal income taxes on the taxable income at regular corporate rates and will not be permitted to qualify for treatment as a REIT for federal income tax purposes for four years following the year during which qualification is lost unless the Internal Revenue Service ("IRS") grants the Company relief under certain statutory provisions. Such an event could materially adversely affect net income and net cash available for distribution to stockholders. As of June 30, 2021, the Company satisfied the REIT requirements and distributed all of its taxable income. Pursuant to the Code, the Company has elected to treat its corporate subsidiary as a taxable REIT subsidiary (a "TRS"). In general, the TRS may perform non-customary services for the Company’s tenants and may engage in any real estate or non-real estate-related business. The TRS will be subject to corporate federal and state income tax. Goodwill Goodwill represents the excess of consideration paid over the fair value of underlying identifiable net assets of business acquired. The Company's goodwill has an indeterminate life and is not amortized, but is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company takes a qualitative approach to consider whether an impairment of goodwill exists prior to quantitatively determining the fair value of the reporting unit in step one of the impairment test. The Company performs its annual assessment on October 1st. Recently Issued Accounting Pronouncements Changes to GAAP are established by the FASB in the form of ASUs to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. Other than the ASUs discussed below, the FASB has not recently issued any other ASUs that the Company expects to be applicable and have a material impact on the Company's financial statements.

Real Estate [Abstract]
Real Estate	Real Estate As of June 30, 2021, the Company’s real estate portfolio consisted of 121 properties (including one land parcel held for future development), in 26 states consisting substantially of office, warehouse, and manufacturing facilities with a combined acquisition value of approximately $5.3 billion, including the allocation of the purchase price to above and below-market lease valuation. Depreciation expense for buildings and improvements for the six months ended June 30, 2021 was $59.3 million. Amortization expense for intangibles, including, but not limited to, tenant origination and absorption costs for the six months ended June 30, 2021, was $40.2 million. 2021 Acquisition CCIT II Merger The CCIT II Merger was accounted for as an asset acquisition under ASC 805, with the Company treated as the accounting acquirer. The total purchase price was allocated to the individual assets acquired and liabilities assumed based upon their relative fair values. Intangible assets were recognized at their relative fair values in accordance with ASC 350, Intangibles. Based on an evaluation of the relevant factors and the guidance in ASC 805 requiring significant management judgment, the entity considered the acquirer for accounting purposes is also the legal acquirer. In order to make this consideration, various factors have been analyzed including which entity issued its equity interests, relative voting rights, existence of minority interests (if any), control of the board of directors, management composition, existence of a premium as it applies to the exchange ratio, relative size, transaction initiation, operational structure, relative composition of employees, surviving brand and name, and other factors. The strongest factor identified was the relative size of the Company as compared to CCIT II. Based on financial measures, the Company was a significantly larger entity than CCIT II and its stockholders hold the majority of the voting shares of the Company. The assets (including identifiable intangible assets) and liabilities (including executory contracts and other commitments) of CCIT II as of the effective time of the CCIT II Merger were recorded at their respective relative fair values and added to those of the Company. Transaction costs incurred by the Company were capitalized in the period in which the costs were incurred and services were received. The total purchase price was allocated to the individual assets acquired and liabilities assumed based upon their relative fair values. Intangible assets were recognized at their relative fair values in accordance with ASC 805. Upon the effective time of the CCIT II Merger on March 1, 2021, each of CCIT II's 67.1 million issued and outstanding shares of common stock were converted into the right to receive 1.392 newly issued shares of the Class E common stock of the Company (approximately 93.5 million shares). Total consideration transferred is calculated as such: As of March 1, 2021 CCIT II's common stock shares prior to conversion 67,139,129 Exchange ratio 1.392 Implied GRT common stock issued as consideration 93,457,668 GRT's Class E NAV per share in effect at March 1, 2021 $ 8.97 Total consideration $ 838,315 The following table summarizes the final purchase price allocation based on a valuation report prepared by the Company's third-party valuation specialist that was subject to management's review and approval: March 1, 2021 Assets: Cash assumed $ 2,721 Land 143,724 Building and improvements 992,779 Tenant origination and absorption cost 152,793 In-place lease valuation (above market) 11,591 Intangibles 27,788 Other assets 1,690 Total assets $ 1,333,086 Liabilities: Debt $ 415,926 In-place lease valuation (below market) 10,026 Lease liability 4,616 Accounts payable and other liabilities 20,604 Total liabilities $ 451,172 Fair value of net assets acquired 881,914 Less: GRT's CCIT II Merger expenses 43,599 Fair value of net assets acquired, less GRT's CCIT II Merger expenses $ 838,315 Merger-Related Expenses In connection with the CCIT II Merger, the Company incurred various transaction and administrative costs. These costs included advisory fees, legal, tax, accounting, valuation fees, and other costs. These costs were capitalized as a component of the cost of the assets acquired. The following is a breakdown of the Company's costs incurred related to the CCIT II Merger: Amount Termination fee of the CCIT II advisory agreement $ 28,439 Advisory and valuation fees 4,699 Legal, accounting and tax fees 5,115 Other fees 5,346 Total CCIT II Merger-related fees $ 43,599 Real Estate - Valuation and Purchase Price Allocation The Company allocates the purchase price to the relative fair value of the tangible assets of a property by valuing the property as if it were vacant. This “as-if vacant” value is estimated using an income, or discounted cash flow, approach that relies upon Level 3 inputs, which are unobservable inputs based on the Company's review of the assumptions a market participant would use. These Level 3 inputs include discount rates, capitalization rates, market rents and comparable sales data for similar properties. Estimates of future cash flows are based on a number of factors including historical operating results, known and anticipated trends, and market and economic conditions. In calculating the “as-if vacant” value for the properties acquired during the six months ended June 30, 2021, the Company used a discount rate range of 5.75% to 8.75%. In determining the fair value of intangible lease assets or liabilities, the Company also considers Level 3 inputs. Acquired above and below-market leases are valued based on the present value of the difference between prevailing market rates and the in-place rates measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the term of any below-market fixed rate renewal options for below-market leases, if applicable. The estimated fair value of acquired in-place at-market tenant leases are the costs that would have been incurred to lease the property to the occupancy level of the property at the date of acquisition. Such estimates include the value associated with leasing commissions, legal and other costs, as well as the estimated period necessary to lease such properties that would be incurred to lease the property to its occupancy level at the time of its acquisition. Acquisition costs associated with asset acquisitions are capitalized during the period they are incurred. The following table summarizes the purchase price allocation of the properties acquired during the six months ended June 30, 2021: Acquisition Land Building Improvements Tenant origination and absorption costs Other Intangibles In-place lease valuation - above/(below) market Financing Leases Total (1) CCIT II Properties $ 143,724 (2) $ 958,166 $ 34,613 $ 152,793 $ 27,788 $ 1,565 $ (3,681) $ 1,314,968 (1) The allocations noted above are based on a determination of the relative fair value of the total consideration provided and represent the amount paid including capitalized acquisition costs. (2) Approximately $5.6 million includes land allocation related to the Company's finance leases. Intangibles The Company allocated a portion of the acquired and contributed real estate asset value to in-place lease valuation, tenant origination and absorption cost, and other intangibles, net of the write-off of intangibles as of June 30, 2021 and December 31, 2020: June 30, 2021 December 31, 2020 In-place lease valuation (above market) $ 49,595 $ 43,576 In-place lease valuation (above market) - accumulated amortization (33,018) (35,604) In-place lease valuation (above market), net 16,577 7,972 Ground leasehold interest (below market) 2,254 2,254 Ground leasehold interest (below market) - accumulated amortization (205) (191) Ground leasehold interest (below market), net 2,049 2,063 Intangibles - other 32,028 4,240 Intangibles - other - accumulated amortization (4,739) (4,240) Intangibles - other, net 27,289 — Intangible assets, net $ 45,915 $ 10,035 In-place lease valuation (below market) $ (77,859) $ (68,334) Land leasehold interest (above market) (3,072) (3,072) Intangibles - other (above market) (364) — In-place lease valuation & land leasehold interest - accumulated amortization 46,897 44,073 Intangible liabilities, net $ (34,398) $ (27,333) Tenant origination and absorption cost $ 876,746 $ 740,489 Tenant origination and absorption cost - accumulated amortization (433,232) (412,462) Tenant origination and absorption cost, net $ 443,514 $ 328,027 The following table sets forth the estimated annual amortization (income) expense for in-place lease valuation, net, tenant origination and absorption costs, ground leasehold improvements, other intangibles, and other leasing costs as of June 30, 2021 for the next five years: Year In-place lease valuation, net Tenant origination and absorption costs Ground leasehold interest Other intangibles Other leasing costs 2021 $ (926) $ 41,133 $ (146) $ 753 $ 3,159 2022 $ (2,226) $ 77,052 $ (290) $ 1,494 $ 5,866 2023 $ (2,797) $ 69,852 $ (290) $ 1,494 $ 5,733 2024 $ (1,818) $ 54,883 $ (291) $ 1,498 $ 5,504 2025 $ (1,352) $ 43,299 $ (290) $ 1,494 $ 5,471 2026 $ (1,201) $ 38,683 $ (290) $ 1,494 $ 4,842 Impairments 2200 Channahon Road and Houston Westway I During the six months ended June 30, 2021, in connection with the preparation and review of the Company's financial statements, the Company recorded an impairment provision of approximately $4.2 million as it was determined that the carrying value of the real estate would not be recoverable on two properties. This impairment resulted from change in expected hold period and selling price. In determining the fair value of property, the Company considered Level 3 inputs. See Note 8, Fair Value Measurements, for details. Sale of Properties On April 12, 2021, the Company sold the 2200 Channahon Road property located in Joliet, Illinois for total proceeds of $11.5 million, less closing costs and other closing credits. The property sold for an approximate amount equal to the carrying value. On June 8, 2021, the Company sold the Houston Westway I property located in Houston, Texas for total proceeds of $10.5 million, less closing costs and other closing credits. The property sold for an approximate amount equal to the carrying value. Restricted Cash In conjunction with the acquisition of certain assets, as required by certain lease provisions or certain lenders in conjunction with an acquisition or debt financing, or credits received by the seller of certain assets, the Company assumed or funded reserves for specific property improvements and deferred maintenance, re-leasing costs, and taxes and insurance, which are included on the consolidated balance sheets as restricted cash. Additionally, an ongoing replacement reserve is funded by certain tenants pursuant to each tenant’s respective lease as follows: Balance as of June 30, 2021 December 31, 2020 Cash reserves $ 17,958 $ 20,385 Restricted lockbox 14,290 13,967 Total $ 32,248 $ 34,352

Equity Method Investments and Joint Ventures [Abstract]
Investments in Unconsolidated Entities	Investments in Unconsolidated Entities The interests discussed below are deemed to be variable interests in variable interest entities ("VIEs") and, based on an evaluation of the variable interests against the criteria for consolidation, the Company determined that it is not the primary beneficiary of the investments, as the Company does not have power to direct the activities of the entities that most significantly affect their performance. As such, the interest in the VIEs is recorded using the equity method of accounting in the accompanying consolidated financial statements. Under the equity method, the investments in the unconsolidated entities are stated at cost and adjusted for the Company’s share of net earnings or losses and reduced by distributions. Equity in earnings of real estate ventures is generally recognized based on the allocation of cash distributions upon liquidation of the investment at book value in accordance with the operating agreements. The Company's maximum exposure to losses associated with its unconsolidated investments is primarily limited to its carrying value in the investments. Digital Realty Trust, Inc. In September 2014, the Company, through an SPE wholly-owned by the GRT OP acquired an 80% interest in a joint venture with an affiliate of Digital Realty Trust, Inc. ("Digital") for $68.4 million, which was funded with equity proceeds raised in the Company's public offerings. The gross acquisition value of the property was $187.5 million, plus closing costs, which was partially financed with debt of $102.0 million. The joint venture was created for purposes of directly or indirectly acquiring, owning, financing, operating and maintaining a data center facility located in Ashburn, Virginia (the "Digital Property"). The Digital Property is approximately 132,300 square feet and consists of certain data processing and communications equipment that is fully leased to a social media company and a financial services company with an average remaining lease term of approximately three years. In September 2014, the joint venture entered into a secured term loan (the "Digital Loan") in the amount of approximately $102.0 million. The Digital Loan had an original maturity date of September 9, 2019 and included two extension options of 12 additional months each beyond the original maturity date. On March 29, 2019, the joint venture executed the first 12-month loan extension. Based on the executed extension, the new loan maturity date was September 9, 2020. The extension did not change the loan amount, rate or other substantive terms. The members were also required to issue a $10.2 million stand-by letter of credit, of which the Company's portion was $8.2 million. Since the tenant did not execute a long term extension or sign a new lease with the joint venture, the joint venture elected not to accept the loan extension terms offered by the lender and subsequent discussions did not result in an additional loan extension in 2020. As a result, on September 9, 2020, the lender provided a notice of default for non-payment of the unpaid balance of the non-recourse Digital Loan and exercised its right to draw on the stand-by letter of credit. The Company funded the $8.2 million stand-by letter of credit with cash. As part of the wind up of the joint venture, the Company had recorded a receivable from the Digital managing member of $4.1 million. The $4.1 million payment was received in April 2021 and the Company has written off its remaining investment in the venture. In April 2021, the lender sold the Digital Loan and concurrently, the Digital-GCEAR 1 (Ashburn) joint venture executed a deed in lieu thereby extinguishing any further obligations. The Company is not exposed to any future funding obligations and there are no other future losses expected to arise from this investment.

The credit facility also provides the option, subject to obtaining additional commitments from lenders and certain other customary conditions, to increase the commitments under the Revolving Credit Facility, increase the existing term loans and/or incur new term loans by up to an additional $600 million in the aggregate. As of June 30, 2021, the remaining capacity under the Revolving Credit Facility was $376.5 million. Based on the terms as of June 30, 2021, the interest rate for the credit facility varies based on the consolidated leverage ratio of the GRT OP, us, and our subsidiaries and ranges (a) in the case of the Revolving Credit Facility, from LIBOR plus 1.30% to LIBOR plus 2.20%, (b) in the case of each of the $200M 5-Year Term Loan, the $400M 5-Year Term Loan and the $400M 5-Year Term Loan 2025, from LIBOR plus 1.25% to LIBOR plus 2.15% and (c) in the case of the $150M 7-Year Term Loan, from LIBOR plus 1.65% to LIBOR plus 2.50%.

On March 1, 2021, the Company exercised its right to draw on the $400M 5-Year Term Loan 2025 to repay CCIT II's existing debt balance in connection with the CCIT II Merger. The Second Amended and Restated Credit Agreement provides that the GRT OP must maintain a pool of unencumbered real properties (each a "Pool Property" and collectively the "Pool Properties") that meet certain requirements contained in the Second Amended and Restated Credit Agreement. The agreement sets forth certain covenants relating to the Pool Properties, including, without limitation, the following: • there must be no less than 15 Pool Properties at any time; • no greater than 15% of the aggregate pool value may be contributed by a single Pool Property or tenant; • no greater than 15% of the aggregate pool value may be contributed by Pool Properties subject to ground leases; • no greater than 20% of the aggregate pool value may be contributed by Pool Properties which are under development or assets under renovation; • the minimum aggregate leasing percentage of all Pool Properties must be no less than 90%; and • other limitations as determined by KeyBank upon further due diligence of the Pool Properties. Borrowing availability under the Second Amended and Restated Credit Agreement is limited to the lesser of the maximum amount of all loans outstanding that would result in (i) an unsecured leverage ratio of no greater than 60%, or (ii) an unsecured interest coverage ratio of no less than 2.00:1.00. Guarantors of the KeyBank Loans include the Company, each special purpose entity that owns a Pool Property, and each of the GRT OP's other subsidiaries which owns a direct or indirect equity interest in a SPE that owns a Pool Property. In addition to customary representations, warranties, covenants, and indemnities, the KeyBank Loans require the GRT OP to comply with the following at all times, which will be tested on a quarterly basis: • a maximum consolidated leverage ratio of 60%, or, the ratio may increase to 65% for up to four consecutive quarters after a material acquisition; • a minimum consolidated tangible net worth of 75% of the Company's consolidated tangible net worth at closing of the Revolving Credit Facility, or approximately $2.0 billion, plus 75% of net future equity issuances (including GRT OP Units), minus 75% of the amount of any payments used to redeem the Company's stock or GRT OP Units, minus any amounts paid for the redemption or retirement of or any accrued return on the preferred equity issued under the preferred equity investment made in EA-1 in August 2018 by SHBNPP Global Professional Investment Type Private Real Estate Trust No. 13 (H); • upon consummation, if ever, of an initial public offering, a minimum consolidated tangible net worth of 75% of the Company's consolidated tangible net worth at the time of such initial public offering plus 75% of net future equity issuances (including GRT OP Units) should the Company publicly list its shares; • a minimum consolidated fixed charge coverage ratio of not less than 1.50:1.00; • a maximum total secured debt ratio of not greater than 40%, which ratio will increase by five percentage points for four quarters after closing of a material acquisition that is financed with secured debt; • a minimum unsecured interest coverage ratio of 2.00:1.00; • a maximum total secured recourse debt ratio, excluding recourse obligations associated with interest rate hedges, of 10% of our total asset value; and • aggregate maximum unhedged variable rate debt of not greater than 30% of the Company's total asset value. Furthermore, the activities of the GRT OP, the Company, and the Company's subsidiaries must be focused principally on the ownership, development, operation and management of office, industrial, manufacturing, warehouse, distribution or educational properties (or mixed uses thereof) and businesses reasonably related or ancillary thereto. Debt Covenant Compliance Pursuant to the terms of the Company's mortgage loans and the KeyBank Loans, the GRT OP, in consolidation with the Company, is subject to certain loan compliance covenants. The Company was in compliance with all of its debt covenants as of June 30, 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Interest Rate Contracts	Interest Rate Contracts Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both business operations and economic conditions. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of debt funding and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future known and uncertain cash amounts, the values of which are determined by expected cash payments principally related to borrowings and interest rates. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company does not use derivatives for trading or speculative purposes. Derivative Instruments The Company has entered into interest rate swap agreements to hedge the variable cash flows associated with certain existing or forecasted LIBOR based variable-rate debt, including the Company's KeyBank Loans. The change in the fair value of derivatives designated and qualifying as cash flow hedges is initially recorded in accumulated other comprehensive income ("AOCI") and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest expense as interest payments are made on the Company's variable-rate debt. The following table sets forth a summary of the interest rate swaps at June 30, 2021 and December 31, 2020: Fair Value (1) Current Notional Amounts Derivative Instrument Effective Date Maturity Date Interest Strike Rate June 30, 2021 December 31, 2020 June 30, 2021 December 31, 2020 Liabilities: Interest Rate Swap 3/10/2020 7/1/2025 0.83% $ (610) $ (2,963) $ 150,000 $ 150,000 Interest Rate Swap 3/10/2020 7/1/2025 0.84% (453) (2,023) 100,000 100,000 Interest Rate Swap 3/10/2020 7/1/2025 0.86% (392) (1,580) 75,000 75,000 Interest Rate Swap 7/1/2020 7/1/2025 2.82% (10,469) (13,896) 125,000 125,000 Interest Rate Swap 7/1/2020 7/1/2025 2.82% (8,405) (11,140) 100,000 100,000 Interest Rate Swap 7/1/2020 7/1/2025 2.83% (8,404) (11,148) 100,000 100,000 Interest Rate Swap 7/1/2020 7/1/2025 2.84% (8,472) (11,225) 100,000 100,000 Total $ (37,205) $ (53,975) $ 750,000 $ 750,000 (1) The Company records all derivative instruments on a gross basis in the consolidated balance sheets, and accordingly there are no offsetting amounts that net assets against liabilities. As of June 30, 2021, derivatives in a liability position are included in the line item "Interest rate swap liability" in the consolidated balance sheets at fair value. The LIBO rate as of June 30, 2021 (ef fe ctive date) was 0.10%. The following table sets forth the impact of the interest rate swaps on the consolidated statements of operations for the periods presented: Six Months Ended June 30, 2021 2020 Interest Rate Swap in Cash Flow Hedging Relationship: Amount of (loss) recognized in AOCI on derivatives $ (9,796) $ (38,723) Amount of (gain) loss reclassified from AOCI into earnings under “Interest expense” $ (7,036) $ 1,613 Total interest expense presented in the consolidated statement of operations in which the effects of cash flow hedges are recorded $ 42,177 $ 39,007 During the twelve months subsequent to June 30, 2021, the Company estimates that an additional $13.8 million of its expense will be recognized from AOCI into earnings. Certain agreements with the derivative counterparties contain a provision that if the Company defaults on any of its indebtedness, including a default where repayment of the indebtedness has not been accelerated by the lender within a specified time period, then the Company could also be declared in default on its derivative obligations. As of June 30, 2021 and December 31, 2020, the fair value of interest rate swaps that were in a liability position, which excludes any adjustment for nonperformance risk related to these agreements, was approximately $37.2 million and $54.0 million , respectively. As of June 30, 2021 and December 31, 2020, the Company had not posted any collateral related to these agreements.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company is required to disclose fair value information about all financial instruments, whether or not recognized in the consolidated balance sheets, for which it is practicable to estimate fair value. The Company measures and discloses the estimated fair value of financial assets and liabilities utilizing a fair value hierarchy that distinguishes between data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. This hierarchy consists of three broad levels, as follows: (i) quoted prices in active markets for identical assets or liabilities, (ii) "significant other observable inputs," and (iii) "significant unobservable inputs." "Significant other observable inputs" can include quoted prices for similar assets or liabilities in active markets, as well as inputs that are observable for the asset or liability, such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. "Significant unobservable inputs" are typically based on an entity’s own assumptions, since there is little, if any, related market activity. In instances in which the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level of input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. There were no transfers between the levels in the fair value hierarchy during the six months ended June 30, 2021 and the year ended December 31, 2020. The following table sets forth the assets and liabilities that the Company measures at fair value on a recurring basis by level within the fair value hierarchy as of June 30, 2021 and December 31, 2020: Assets/(Liabilities) Total Fair Value Quoted Prices in Active Markets for Identical Assets and Liabilities Significant Other Observable Inputs Significant Unobservable Inputs June 30, 2021 Interest Rate Swap Liability $ (37,205) $ — $ (37,205) $ — Corporate Owned Life Insurance Asset $ 6,753 $ — $ 6,753 $ — Mutual Funds Asset $ 5,258 $ 5,258 $ — $ — Deferred Compensation Liability $ (8,895) $ — $ (8,895) $ — December 31, 2020 Interest Rate Swap Liability $ (53,975) $ — $ (53,975) $ — Corporate Owned Life Insurance Asset $ 4,454 $ — $ 4,454 $ — Mutual Funds Asset $ 6,643 $ 6,643 $ — $ — Deferred Compensation Liability $ (10,599) $ — $ (10,599) $ — Real Estate For the six months ended June 30, 2021, in connection with the preparation and review of the Company's financial statements, the Company determined that two of the Company's properties were impaired based on expected hold period and selling price. The Company considered these inputs as Level 3 measurements within the fair value hierarchy. The following table is a summary of the quantitative information related to the non-recurring fair value measurement for the impairment of the Company's real estate properties for the six months ended June 30, 2021: Range of Inputs or Inputs Unobservable Inputs: 2200 Channahon Road Houston Westway I Expected selling price per square foot $8.30 $72.90 Estimated hold period Less than one year Less than one year Financial Instruments Disclosed at Fair Value Financial instruments as of June 30, 2021 and December 31, 2020 consisted of cash and cash equivalents, restricted cash, accounts receivable, accrued expenses and other liabilities, and mortgage payable and other borrowings, as defined in Note 5, Debt. With the exception of the mortgage loans in the table below, the amounts of the financial instruments presented in the consolidated financial statements substantially approximate their fair value as of June 30, 2021 and December 31, 2020. The fair value of the ten mortgage loans in the table below is estimated by discounting each loan’s principal balance over the remaining term of the mortgage using current borrowing rates available to the Company for debt instruments with similar terms and maturities. The Company determined that the mortgage debt valuation in its entirety is classified in Level 2 of the fair value hierarchy, as the fair value is based on current pricing for debt with similar terms as the in-place debt.

Equity [Abstract]
Equity	Equity Classes Class T shares, Class S shares, Class D shares, Class I shares, Class A shares, Class AA shares, Class AAA and Class E shares vote together as a single class, and each share is entitled to one vote on each matter submitted to a vote at a meeting of the Company's stockholders; provided that with respect to any matter that would only have a material adverse effect on the rights of a particular class of common stock, only the holders of such affected class are entitled to vote . As of June 30, 2021, there were 562,857 shares of Class T common stock, 1,800 shares of Class S common stock, 41,705 shares of Class D common stock, 1,906,996 shares of Class I common stock, 24,476,465 shares of Class A common stock, 47,527,441 shares of Class AA common stock, 923,897 shares of Class AAA common stock, and 248,469,456 shares of Class E common stock outstanding. Common Equity As of June 30, 2021, the Company had received aggregate gross offering proceeds of approximately $2.8 billion from the sale of shares in the private offering, the public offerings, the DRP offerings and mergers (includes EA-1 offerings and EA-1 merger with Signature Office REIT, Inc., the EA Mergers and the CCIT II Merger), as discussed in Note 1, Organization . As part of the $2.8 billion from the sale of shares, the Company issued approximately 43,772,611 shares of its common stock upon the consummation of the merger of Signature Office REIT, Inc. in June 2015 and 174,981,547 Class E shares (in exchange for all outstanding shares of EA-1's common stock at the time of the EA Mergers) in April 2019 upon the consummation of the EA Mergers and 93,457,668 Class E shares (in exchange for all the outstanding shares of CCIT II's common stock at the time of the CCIT II Merger). As of June 30, 2021, there were 323,910,617 shares outstanding, including shares issued pursuant to the DRP, less shares redeemed pursuant to the SRP and the self-tender offer, which occurred in May 2019. Termination of Follow-On Offering On February 26, 2020, the Board approved the temporary suspension of the primary portion of the Company’s follow-on offering of up to $2.2 billion of shares, consisting of up to $2.0 billion of shares in our primary offering and $0.2 billion of shares pursuant to our DRP (the “Follow-On Offering”), effective February 27, 2020. The Follow-On Offering terminated with the expiration of the registration statement on Form S-11 (Registration No. 333-217223), as amended, on September 20, 2020. Distribution Reinvestment Plan (DRP) The Company has adopted the DRP, which allows stockholders to have dividends and other distributions otherwise distributable to them invested in additional shares of common stock. No sales commissions or dealer manager fees will be paid on shares sold through the DRP, but the DRP shares will be charged the applicable distribution fee payable with respect to all shares of the applicable class. The purchase price per share under the DRP is equal to the net asset value ("NAV") per share applicable to the class of shares purchased, calculated using the most recently published NAV available at the time of reinvestment. The Company may amend or terminate the DRP for any reason at any time upon 10 days' prior written notice to stockholders, which may be provided through the Company's filings with the SEC. In connection with a potential strategic transaction, on February 26, 2020, the Board approved the temporary suspension of the DRP, effective March 8, 2020. On July 16, 2020, the Board approved the reinstatement of the DRP, effective July 27, 2020 and an amendment of the DRP to allow for the use of the most recently published NAV per share of the applicable share class available at the time of reinvestment as the DRP purchase price for each share class. On July 17, 2020, the Company filed a registration statement on Form S-3 for the registration of up to $100 million in shares pursuant to the Company's DRP (the “DRP Offering”). The DRP Offering may be terminated at any time upon 10 days’ prior written notice to stockholders. The following table summarizes the DRP offerings, by share class, as of June 30, 2021: Share Class Amount Shares Class A $ 8,765 950,007 Class AA 17,273 1,871,708 Class AAA 263 28,482 Class D 18 1,922 Class E 306,201 31,727,673 Class I 393 42,206 Class S — 12 Class T 155 16,682 Total $ 333,068 34,638,692 As of June 30, 2021 and December 31, 2020, the Company had issued approximately $333.1 million and $318.2 million in shares pursuant to the DRP offerings, respectively. Share Redemption Program (SRP) The Company has adopted the SRP that enables stockholders to sell their stock to the Company in limited circumstances. On August 8, 2019, the Board amended and restated its SRP, effective as of September 12, 2019, in order to (i) clarify that only those stockholders who purchased their shares from us or received their shares from the Company (directly or indirectly) through one or more non-cash transactions (including transfers to trusts, family members, etc.) may participate in the SRP; (ii) allocate capacity within each class of common stock such that the Company may redeem up to 5% of t he aggregate NAV of each class of common stock; (iii) treat all unsatisfied redemption requests (or portion thereof) as a request for redemption the following quarter unless otherwise withdrawn; and (iv) make certain other clarifying changes. On November 7, 2019, the Board amended and restated the SRP, effective as of December 12, 2019, in order to (i) provide for redemption sought upon a stockholder’s determination of incompetence or incapacitation; (ii) clarify the circumstances under which a determination of incompetence or incapacitation will entitle a stockholder to such redemption; and (iii) make certain other clarifying changes. In connection with a potential strategic transaction, on February 26, 2020, the Board approved the temporary suspension of the SRP, effective March 28, 2020. On July 16, 2020, the Board approved the partial reinstatement of the SRP, effective August 17, 2020, subject to the following limitations: (A) redemptions will be limited to those sought upon a stockholder’s death, qualifying disability, or determination of incompetence or incapacitation in accordance with the terms of the SRP, and (B) the quarterly cap on aggregate redemptions will be equal to the aggregate NAV, as of the last business day of the previous quarter, of the shares issued pursuant to the DRP during such quarter. Settlements of share redemptions will be made within the first three business days of the following quarter. Redemption activity during the quarter is listed below. Under the SRP, the Company will redeem shares as of the last business day of each quarter. The redemption price will be equal to the NAV per share for the applicable class generally on the 13th day of the month prior to quarter end (which will be the most recently published NAV). Redemption requests must be received by 4:00 p.m. (Eastern time) on the second to last business day of the applicable quarter. Redemption requests exceeding the quarterly cap will be filled on a pro rata basis. With respect to any pro rata treatment, redemption requests following the death or qualifying disability of a stockholder will be considered first, as a group, followed by requests where pro rata redemption would result in a stockholder owning less than the minimum balance of $2,500 of shares of the Company's common stock, which will be redeemed in full to the extent there are available funds, with any remaining available funds allocated pro rata among all other redemption requests. All unsatisfied redemption requests must be resubmitted after the start of the next quarter, or upon the recommencement of the SRP, as applicable. There are several restrictions under the SRP. Stockholders generally must hold their shares for one year before submitting their shares for redemption under the program; however, the Company will waive the one-year holding period in the event of the death or qualifying disability of a stockholder. Shares issued pursuant to the DRP are not subject to the one-year holding period. In addition, the SRP generally imposes a quarterly cap on aggregate redemptions of the Company's shares equal to a value of up to 5% of the aggregate NAV of the outstanding shares as of the last business day of the previous quarter, subject to the further limitations as indicated in the August 8, 2019 amendments discussed above. As the value on the aggregate redemptions of the Company's shares is outside the Company's control, the 5% quarterly cap is considered to be temporary equity and is presented as common stock subject to redemption on the accompanying consolidated balance sheets. The following table summarizes share redemption (excluding the self-tender offer) activity during the three and six months ended June 30, 2021 and 2020: Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Shares of common stock redeemed 871,550 301 1,643,814 548,613 Weighted average price per share $ 9.06 $ 9.33 $ 9.01 $ 9.32 Since July 31, 2014 and through June 30, 2021, the Company had redeemed 27,716,267 shares (excluding the self-tender offer) of common stock for approximately $260.1 million at a weighted average price per share of $9.38 pursuant to the SRP. Since July 31, 2014 and through December 31, 2019, the Company had honored all outstanding redemption requests. During the three months ended September 30, 2019, redemption requests for Class E shares exceeded the quarterly 5% per share class limitation by 2,872,488 shares or approximately $27.4 million. The Class E shares not redeemed during that quarter, or 25% of the shares submitted, were treated as redemption requests for the quarter ended December 31, 2019. All outstanding requests for the quarter ended September 30, 2019 and all new requests for the quarter ended December 31, 2019 were honored on January 2, 2020. Redemptions sought upon a stockholder's death, qualifying disability, or determination of incompetence or incapacitation in the first quarter of 2020 were honored in accordance with the terms of the SRP, and the SRP officially was suspended as of March 28, 2020 for regular redemptions and subsequent redemptions for death, qualifying disability, or determination of incompetence or incapacitation after those honored in the first quarter of 2020. As described above, the SRP was partially reinstated, effective August 17, 2020, for redemptions sought upon a stockholder’s death, qualifying disability, or determination of incompetence or incapacitation in accordance with the terms of the SRP, subject to a quarterly cap on aggregate redemptions equal to the aggregate NAV, as of the last business day of the previous quarter, of the shares issued pursuant to the DRP during such quarter. During the three months ended June 30, 2021, the Company received redemption requests (including those due to death, disability or incapacitation) for 437,298 shares of common stock that were not redeemed during the current quarter. Issuance of Restricted Stock Units to Executive Officers and Employees On May 1, 2019, the Company issued 1,009,415 restricted stock units ("RSUs") to the Company's officers under the Employee and Director Long-Term Incentive Plan of Griffin Capital Essential Asset REIT II, Inc.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Noncontrolling interests represent limited partnership interests in the GRT OP in which the Company is the general partner. General partnership units and limited partnership units of the GRT OP were issued as part of the initial capitalization of the GRT OP and GCEAR II Operating Partnership, in conjunction with members of management's contribution of certain assets, other contributions, and in connection with the self-administration transaction as discussed in Note 1, Organization. As of June 30, 2021, noncontrolling interests were approximately 9.0% of total shares and 9.6% of weighted average shares outstanding (both measures assuming GRT OP Units were converted to common stock). The Company has evaluated the terms of the limited partnership interests in the GRT OP, and as a result, has classified limited partnership interests issued in the initial capitalization, in conjunction with the contributed assets and in connection with the self-administration transaction, as noncontrolling interests, which are presented as a component of permanent equity, except as discussed below. The Company evaluates individual noncontrolling interests for the ability to recognize the noncontrolling interest as permanent equity on the consolidated balance sheets at the time such interests are issued and on a continual basis. Any noncontrolling interest that fails to qualify as permanent equity has been reclassified as temporary equity and adjusted to the greater of (a) the carrying amount or (b) its redemption value as of the end of the period in which the determination is made. As of June 30, 2021, the limited partners of the GRT OP owned approximately 31.8 million GRT OP Units, which were issued to affiliated parties and unaffiliated third parties in exchange for the contribution of certain properties to the Company, and in connection with the self-administration transaction and other services. Approximately 20.4 million GRT OP Units issued to affiliates had a mandatory hold period until December 2020 and had no voting rights until the units convert to common shares. In addition, 0.2 million GRT OP Units were issued to unaffiliated third parties unrelated to property contributions. To the extent the contributors should elect to redeem all or a portion of their GRT OP Units, pursuant to the terms of the respective contribution agreement, such redemption shall be at a per unit value equivalent to the price at which the contributor acquired its GRT OP Units in the respective transaction. The limited partners of the GRT OP, other than those related to the Will Partners REIT, LLC ("Will Partners") property contribution, will have the right to cause the general partner of the GRT OP, the Company, to redeem their GRT OP Units for cash equal to the value of an equivalent number of shares, or, at the Company’s option, purchase their GRT OP Units by issuing one share of the Company’s common stock for the original redemption value of each limited partnership unit redeemed. The Company has the control and ability to settle such requests in shares. These rights may not be exercised under certain circumstances which could cause the Company to lose its REIT election. The following summarizes the activity for noncontrolling interests recorded as equity for the six months ended June 30, 2021 and year ended December 31, 2020: Six Months Ended June 30, 2021 Year Ended December 31, 2020 Beginning balance $ 226,550 $ 245,040 Reclass of noncontrolling interest subject to redemption (62) 224 Repurchase of noncontrolling interest — (1,137) Issuance of stock dividend for noncontrolling interest — 1,068 Distributions to noncontrolling interests (5,426) (13,306) Allocated distributions to noncontrolling interests subject to redemption (9) (29) Net (loss) (277) (1,732) Other comprehensive income (loss) 1,782 (3,578) Ending balance $ 222,558 $ 226,550 Noncontrolling interests subject to redemption Operating partnership units issued pursuant to the Will Partners property contribution are not included in permanent equity on the consolidated balance sheets. The partners holding these units can cause the general partner to redeem the units for the cash value, as defined in the GRT OP agreement. As the general partner does not control these redemptions, these units are presented on the consolidated balance sheets as noncontrolling interest subject to redemption at their redeemable value. The net income (loss) and distributions attributed to these limited partners is allocated proportionately between common stockholders and other noncontrolling interests that are not considered redeemable.

The terms of the Dealer Manager Agreement are substantially similar to the terms of the dealer manager agreement from the Company's initial public offering ("IPO"), except as it relates to the share classes offered and the fees to be received by the dealer manager. The Follow-On Offering terminated on September 20, 2020. See Note 9, Equity. Subject to the Financial Industry Regulatory Authority, Inc.'s limitations on underwriting compensation, under the Dealer Manager Agreement the Company required payment to the dealer manager of a distribution fee for ongoing services rendered to stockholders by participating broker-dealers or broker-dealers servicing investors’ accounts, referred to as servicing broker-dealers. The fee accrued daily, is paid monthly in arrears, and is calculated based on the average daily NAV for the applicable month. Conflicts of Interest Affiliated Former Dealer Manager Since Griffin Capital Securities, LLC, the Company's former dealer manager, is an affiliate of the Company's former sponsor, the Company did not have the benefit of an independent due diligence review and investigation of the type normally performed by an unaffiliated, independent underwriter in connection with the offering of securities. The Company's former dealer manager is also serving as the dealer manager for Griffin-American Healthcare REIT III, Inc. and Griffin-American Healthcare REIT IV, Inc., each of which are publicly-registered, non-traded REITs, as wholesale marketing agent for Griffin Institutional Access Real Estate Fund and Griffin Institutional Access Credit Fund both of which are non-diversified, closed-end management investment companies that are operated as interval funds under the 1940 Act, and as dealer manager or master placement agent for various private offerings. Administrative Services Agreement In connection with the EA Mergers, the Company assumed, as the successor of EA-1 and the GRT OP, an Administrative Services Agreement (the "Administrative Services Agreement"), pursuant to which Griffin Capital Company, LLC ("GCC") and Griffin Capital, LLC ("GC LLC") continue to provide office space and certain operational and administrative services at cost to the GRT OP, Griffin Capital Essential Asset TRS, Inc., and Griffin Capital Real Estate Company, LLC ("GRECO"), which may include, without limitation, the shared information technology, human resources, legal, due diligence, marketing, customer service, events, operations, accounting and administrative support services set forth in the Administrative Services Agreement. The Company pays GCC a monthly amount based on the actual costs anticipated to be incurred by GCC for the provision of such office space and services until the Company elects to provide such space and/or services for itself or through another provider, which amount is initially $0.2 million per month, based on an approved budget. Such costs are reconciled quarterly and a full review of the costs will be performed at least annually. In addition, the Company will directly pay or reimburse GCC for the actual cost of any reasonable third-party expenses incurred in connection with the provision of such services. Certain Conflict Resolution Procedures Every transaction that the Company enters into with affiliates is subject to an inherent conflict of interest. The Board may encounter conflicts of interest in enforcing the Company's rights against any affiliate in the event of a default by or disagreement with an affiliate or in invoking powers, rights or options pursuant to any agreement between the Company and affiliates. See the Company's Code of Ethics available at the "Governance Documents" subpage of the investors section of the Company's website at www.grtreit.com for a detailed description of the Company's conflict resolution procedures.

Leases [Abstract]
Leases	Leases Lessor The Company leases commercial and industrial space to tenants primarily under non-cancelable operating leases that generally contain provisions for minimum base rents plus reimbursement for certain operating expenses. Total minimum lease payments are recognized in rental income on a straight-line basis over the term of the related lease and estimated reimbursements from tenants for real estate taxes, insurance, common area maintenance and other recoverable operating expenses are recognized in rental income in the period that the expenses are incurred. The Company recognized $182.3 million and $155.7 million of lease income related to operating lease payments for the six months ended June 30, 2021 and 2020, respectively.

Basis of Presentation and Sum_2

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2021
Accounting Policies [Abstract]
Basis of Accounting	The accompanying unaudited consolidated financial statements of the Company are prepared by management on the accrual basis of accounting and in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information as contained in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), and in conjunction with rules and regulations of the SEC. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements.
Consolidation	The consolidated financial statements of the Company include all accounts of the Company, the GRT OP, and its subsidiaries. Intercompany transactions are not shown on the consolidated statements. However, each property-owning entity is a wholly-owned subsidiary which is a special purpose entity ("SPE"), whose assets and credit are not available to satisfy the debts or obligations of any other entity, except to the extent required with respect to any co-borrower or guarantor under the same credit facility.
Use of Estimates	Use of Estimates The preparation of the unaudited consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates.
Change in Consolidated Financial Statements Presentation	Change in Consolidated Financial Statements Presentation Certain amounts in the Company's prior period consolidated financial statements have been reclassified to conform to the current period presentation. Investment in unconsolidated entities has been reclassified to other assets on the Company's consolidated balance sheets all periods presented.
Per Share Data	Per Share Data The Company reports earnings per share for the period as (1) basic earnings per share computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding during the period, and (2) diluted earnings per share computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding, including common stock equivalents. As of June 30, 2021 and December 31, 2020, there were no material common stock equivalents that would have a dilutive effect on earnings (loss) per share for common stockholders.
Segment Information	Segment Information ASC 280, Segment Reporting, establishes standards for reporting financial and descriptive information about a public entity’s reportable segments. The Company internally evaluates all of the properties and interests therein as one reportable segment.
Income Taxes	Income Taxes The Company has elected to be taxed as a REIT under the Internal Revenue Code ("Code"). To qualify as a REIT, the Company must meet certain organizational and operational requirements. The Company intends to adhere to these requirements and maintain its REIT status for the current year and subsequent years. As a REIT, the Company generally will not be subject to federal income taxes on taxable income that is distributed to stockholders. However, the Company may be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed taxable income, if any. If the Company fails to qualify as a REIT in any taxable year, the Company will then be subject to federal income taxes on the taxable income at regular corporate rates and will not be permitted to qualify for treatment as a REIT for federal income tax purposes for four years following the year during which qualification is lost unless the Internal Revenue Service ("IRS") grants the Company relief under certain statutory provisions. Such an event could materially adversely affect net income and net cash available for distribution to stockholders. As of June 30, 2021, the Company satisfied the REIT requirements and distributed all of its taxable income.
Goodwill	Goodwill Goodwill represents the excess of consideration paid over the fair value of underlying identifiable net assets of business acquired. The Company's goodwill has an indeterminate life and is not amortized, but is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company takes a qualitative approach to consider whether an impairment of goodwill exists prior to quantitatively determining the fair value of the reporting unit in step one of the impairment test. The Company performs its annual assessment on October 1st.
Recently Issued Accounting Pronouncements and Adoption of New Accounting Pronouncements	Recently Issued Accounting Pronouncements Changes to GAAP are established by the FASB in the form of ASUs to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. Other than the ASUs discussed below, the FASB has not recently issued any other ASUs that the Company expects to be applicable and have a material impact on the Company's financial statements. Adoption of New Accounting Pronouncements
