Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	Inland Real Estate Income Trust, Inc. (the “Company”) was formed on August 24, 2011 to acquire and manage a portfolio of commercial real estate investments located in the United States. The Company is primarily focused on acquiring retail properties and targets a portfolio of 100% grocery-anchored properties The Company has no employees. The Company is managed by IREIT Business Manager & Advisor, Inc. (the “Business Manager”), an indirect wholly owned subsidiary of Inland Real Estate Investment Corporation (the “Sponsor”), pursuant to a Business Management Agreement with the Business Manager. On January 16, 2018, the Company effected a 1-for-2.5 reverse stock split of its issued and outstanding common stock whereby every 2.5 shares of issued and outstanding common stock were converted into one share of its common stock (the “Reverse Stock Split”). In accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), all share information presented has been retroactively adjusted to reflect the Reverse Stock Split. On February 11, 2019, the Company’s board of directors approved a strategic plan (the “Strategic Plan”) with the goals of providing future liquidity to investors and creating long-term stockholder value. The Strategic Plan centers around owning a portfolio of 100% grocery-anchored properties with lower exposure to big box retailers. Consistent with the Strategic Plan, the Company sold 12 properties in 2019 and three additional properties in 2020, as further described in Note 5 – “Dispositions” and Note 18 – “Subsequent Events.” The Company’s management team and board are considering the opportunistic sale of certain other assets with the goal of redeploying capital into the acquisition of strategically located grocery-anchored centers, as well as the redevelopment of select centers within the current portfolio. The Company is considering moving toward a liquidity event in approximately two years, market conditions permitting, most likely through a listing on a public securities exchange. In connection with the Strategic Plan, the Company’s share repurchase program (as amended, the “SRP”) was amended and restated, effective March 21, 2019, and the Business Management Agreement with the Business Manager was amended and restated on February 11, 2019 to, among other things, eliminate all future acquisition and disposition fees. On March 3, 2020, the Company’s SRP was amended and restated (the “Third A&R SRP”), which will become effective on April 10, 2020, as further described below in . On March 3, 2020, as reported in the Company’s Form 8-K filed with the Securities and Exchange Commission on the same date, the Company announced that the Company’s board of directors unanimously approved: (i) an estimated per share net asset value (the “Estimated Per Share NAV”) as of December 31, 2019; (ii) the same per share purchase price for shares issued under the Company’s distribution reinvestment plan (as amended, the “DRP”) beginning with the first quarter distribution payment to stockholders in April 2020 until the Company announces a new Estimated Per Share NAV, and (iii) that, in accordance with the SRP, beginning with repurchases in April 2020 and until the Company announces a new Estimated Per Share NAV, any shares accepted for ordinary repurchases and “exceptional repurchases” will be repurchased at 80% of the Estimated Per Share NAV. At December 31, 2019, the Company owned 47 retail properties, totaling 6,758,359 square feet. The properties are located in 23 states. At December 31, 2019, the portfolio had a weighted average physical occupancy of 94.0% and economic occupancy of 94.4%.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES General The consolidated financial statements have been prepared in accordance with U.S. GAAP and require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. In the opinion of management, all adjustments necessary for a fair statement, in all material respects, of the financial position and results of operations for the periods are presented. Actual results could differ from those estimates. Information with respect to square footage and occupancy is unaudited. Certain amounts in the prior period consolidated financial statements have been reclassified to conform with the current year presentation. Consolidation The consolidated financial statements include the accounts of the Company, as well as all wholly owned subsidiaries. Wholly owned subsidiaries generally consist of limited liability companies (“LLCs”). All intercompany balances and transactions have been eliminated in consolidation. Each property is owned by a separate legal entity which maintains its own books and financial records and each entity’s assets are not available to satisfy the liabilities of other affiliated entities. The fiscal year-end of the Company is December 31. Partially-Owned Entities The Company will consolidate the operations of a joint venture if the Company determines that it is either the primary beneficiary of a variable interest entity (VIE) or has substantial influence and control of the entity. In instances where the Company determines that it is not the primary beneficiary of a VIE or the Company does not control the joint venture but can exercise influence over the entity with respect to its operations and major decisions, the Company will use the equity method of accounting. Under the equity method, the operations of a joint venture will not be consolidated with the Company’s operations but instead its share of operations will be reflected as equity in earnings (loss) of unconsolidated entity on its consolidated statements of operations and comprehensive loss. Additionally, the Company’s net investment in the joint venture will be reflected as investment in unconsolidated entity on the consolidated balance sheets. Acquisitions Upon acquisition of real estate investment properties, the Company allocates the total purchase price of each property that is accounted for as an asset acquisition based on the relative fair value of the tangible and intangible assets acquired and liabilities assumed based on Level 3 inputs, such as comparable sales values, discount rates, capitalization rates, revenue and expense growth rates and lease-up assumptions, from a third party appraisal or other market sources. The acquisition date is the date on which the Company obtains control of the real estate investment property and transaction costs are capitalized. Assets and liabilities acquired typically include land, building and site improvements and identified intangible assets and liabilities, consisting of the value of above market and below market leases and the value of in-place leases. The portion of the purchase price allocated to above market lease values is included in acquired lease intangible assets, net and is amortized on a straight-line basis over the term of the related lease as a reduction to rental income. The portion allocated to below market lease values is included in acquired intangible liabilities, net and is amortized as an increase to rental income over the term of the lease including any renewal periods with fixed rate renewals. The portion of the purchase price allocated to acquired in-place lease value is included in acquired lease intangible assets, net and is amortized on a straight-line basis over the acquired leases’ weighted average remaining term. The Company determines the fair value of the tangible assets consisting of land and buildings by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land and buildings. The Company determines the fair value of assumed debt by calculating the net present value of the mortgage payments using interest rates for debt with similar terms and maturities. Differences between the fair value and the stated value is recorded as a discount or premium and amortized over the remaining term using the effective interest method. Certain of the Company’s properties included earnout components to the purchase price, meaning the Company did not pay a portion of the purchase price of the property at closing, although the Company owns the entire property. The Company is not obligated to settle the contingent portion of the purchase price unless space which was vacant at the time of acquisition is later leased by the seller within the time limits and parameters set forth in the related acquisition agreements. The Company’s policy is to record earnout components when estimable and probable. At December 31, 2019, there is no earnout liability outstanding. Impairment of Investment Properties and Equity Method Investments The Company assesses the carrying values of its respective long-lived assets whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. Recoverability of the assets is measured by comparison of the carrying amount of the asset to the estimated future undiscounted cash flows. In order to review its assets for recoverability, the Company considers current market conditions, as well as its intent with respect to holding or disposing of the asset. If the Company’s analysis indicates that the carrying value of the long-lived asset is not recoverable on an undiscounted cash flow basis, the Company recognizes an impairment charge for the amount by which the carrying value exceeds the current estimated fair value of the real estate property. Fair value is determined through various valuation techniques, including discounted cash flow models, quoted market values and third party appraisals, where considered necessary (Level 3 inputs). The Company estimates the future undiscounted cash flows based on management’s intent as follows: (i) for real estate properties that the Company intends to hold long-term, including land held for development, properties currently under development and operating buildings, recoverability is assessed based on the estimated future net rental income from operating the property and termination value; and (ii) for real estate properties that the Company intends to sell, including land parcels, properties currently under development and operating buildings, recoverability is assessed based on estimated net proceeds, including net rental income during the holding period, from disposition that are estimated based on future net rental income of the property and utilizing expected market capitalization rates. The use of projected future cash flows is based on assumptions that are consistent with our estimates of future expectations and the strategic plan the Company uses to manage its underlying business. However, assumptions and estimates about future cash flows, including comparable sales values, discount rates, capitalization rates, revenue and expense growth rates and lease-up assumptions which impact the discounted cash flow approach to determining value are complex and subjective. Changes in economic and operating conditions and the Company’s ultimate investment intent that occur subsequent to the impairment analysis could impact these assumptions and result in future impairment charges of real estate properties. On a quarterly basis, management assesses whether there are any indicators that the carrying value of the Company’s investment in unconsolidated entities and notes receivable may be other than temporarily impaired as a loss in value that is other than a temporary decline is required to be recognized. Indicators include significant delays in construction, significant costs over budget and financial concerns. To the extent indicators suggest that a loss in value may have occurred, the Company will evaluate both quantitative and qualitative factors to determine if the loss in value is other than temporary. If a potential loss in value is determined to be other than temporary, the Company will recognize an impairment loss based on the estimated fair value of the investment. During the year ended December 31, 2019, the Company recorded an impairment charge of $4,420 which is included in provision for asset impairment on the consolidated statement of operations and comprehensive loss. During the year ended December 31, 2018, the Company recorded an impairment charge of $9,865 related to its investment in Mainstreet Texas Development Fund, LLC, a joint venture formed to develop three transitional care/rapid recovery centers (“Mainstreet JV”). The Company determined that, as of December 31, 2018, collection of its note receivable from Mainstreet JV is improbable and therefore, recorded an impairment charge of $5,540 to reduce the note receivable balance to zero. Both impairment charges related to Mainstreet JV are included in provision for impairment of investment in and note receivable from unconsolidated entities on the consolidated statement of operations and comprehensive loss. During the year ended December 31, 2017, the Company recorded an impairment charge of $8,530 which is included in provision for asset impairment on the consolidated statement of operations and comprehensive loss. REIT Status The Company elected to be taxed as a real estate investment trust (“REIT”) under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended, for federal income tax purposes commencing with the tax year ended December 31, 2013. Commencing with such taxable year, the Company was organized and began operating in such a manner as to qualify for taxation as a REIT under the Internal Revenue Code and believes it has so qualified. As a result, the Company generally will not be subject to federal income tax on taxable income that is distributed to stockholders. A REIT is subject to a number of organizational and operational requirements, including a requirement that it currently distributes at least 90% of its REIT taxable income (subject to certain adjustments and excluding any net capital gain) to its stockholders. The Company will monitor the business and transactions that may potentially impact its REIT status. If the Company fails to qualify as a REIT in any taxable year, without the benefit of certain statutory relief provisions, the Company will be subject to tax as a “C corporation.” Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income, property or net worth and federal income and excise taxes. Any taxable REIT subsidiaries generally will be subject to federal income tax applicable to “C corporations.” Cash and Cash Equivalents The Company considers all demand deposits, money market accounts and all short-term investments with a maturity of three months or less, at the date of purchase, to be cash equivalents. The account balance may exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there could be a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company believes that the risk will not be significant, as the Company does not anticipate the financial institutions’ non-performance. Restricted Cash Amounts included in restricted cash represent those required to be set aside by lenders for real estate taxes, insurance, capital expenditures and tenant improvements on our existing properties. These amounts also include post close escrows for tenant improvements, leasing commissions, master lease, general repairs and maintenance, and are classified as restricted cash on the Company’s consolidated balance sheets. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported on the Company’s consolidated balance sheets to such amounts shown on the Company’s consolidated statements of cash flows: December 31, 2019 2018 Cash and cash equivalents $ 4,516 $ 15,239 Restricted cash 1,017 1,001 Total cash, cash equivalents, and restricted cash $ 5,533 $ 16,240 Accounts and Rents Receivable The Company takes into consideration certain factors that require judgments to be made as to the collectability of receivables. Collectability factors taken into consideration are the amounts outstanding and payment history of the tenant. The Company includes both billed and accrued charges in its evaluation of the collectability of a tenant’s receivable balance. For tenant receivables that the Company determines to be uncollectible, the Company records an offset for uncollectable tenant revenues directly to rental income. Capitalization and Depreciation Real estate properties held and used are recorded at cost less accumulated depreciation. Real estate properties held for sale are recorded at the lesser of their carrying value or fair value less selling costs. Improvement and betterment costs are capitalized, and ordinary repairs and maintenance are expensed as incurred. Real estate properties are classified as held for sale when the Company concludes that a sale is likely. Criteria that may be considered in this determination include obtaining a signed purchase and sale agreement, the completion and waiving of due diligence by the seller, and the receipt of non-refundable earnest money from the seller. Cost capitalization and the estimate of useful lives require judgment and include significant estimates that can and do change. Depreciation expense is computed using the straight-line method. The Company anticipates the estimated useful lives of its assets by class to be generally: Building and other improvements 30 years Site improvements 5-15 years Furniture, fixtures and equipment 5-15 years Tenant improvements Shorter of the life of the asset or the term of the related lease Leasing fees Term of the related lease Depreciation expense was $39,304, $38,040 and $39,497 for the years ended December 31, 2019, 2018 and 2017, respectively. Amortization of leasing fees were $546, $360, and $168 for the years ended December 31, 2019, 2018 and 2017, respectively. Debt Issuance Costs Debt issuance costs are amortized on a straight-line basis, which approximates the effective interest method, over the term, or anticipated repayment date, of the related agreements as a component of interest expense. These costs are reported as a direct deduction to the Company’s outstanding mortgages and credit facility payable. Fair Value Measurements The Company has estimated fair value using available market information and valuation methodologies the Company believes to be appropriate for these purposes. Considerable judgment and a high degree of subjectivity are involved in developing these estimates and, accordingly, they are not necessarily indicative of amounts that would be realized upon disposition. The Company defines fair value based on the price that it believes would be received upon sale of an asset or the exit price that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value. The fair value hierarchy consists of three broad levels, which are described below: Level 1 − Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access. Level 2 − Observable inputs, other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 − Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The Company’s cash equivalents, accounts receivable and payables and accrued expenses all approximate fair value due to the short term nature of these financial instruments. The Company’s financial instruments measured on a recurring basis include derivative interest rate instruments. Derivatives The Company uses derivative instruments, such as interest rate swaps, primarily to manage exposure to interest rate risks inherent in variable rate debt. The Company may also enter into forward starting swaps or treasury lock agreements to set the effective interest rate on a planned fixed-rate financing. The Company’s interest rate swaps involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. In a forward starting swap or treasury lock agreement that the Company cash settles in anticipation of a fixed rate financing or refinancing, the Company will receive or pay an amount equal to the present value of future cash flow payments based on the difference between the contract rate and market rate on the settlement date. The Company does not use derivatives for trading or speculative purposes and currently does not have any derivatives that are not designated as hedging instruments under the accounting requirements for derivatives and hedging. Revenue Recognition The Company commences revenue recognition for its operating leases on the commencement date of the lease, which the Company considers is the date on which it makes the leased space available to the lessee. The determination of who is the owner, for accounting purposes, of the tenant improvements determines the nature of the leased asset. If the Company is the owner, for accounting purposes, of the tenant improvements, then the tenant improvements are capitalized and depreciated over the life of the lease. If the Company concludes it is not the owner, for accounting purposes, of the tenant improvements (the lessee is the owner), then the leased asset is the unimproved space and any tenant improvement allowances funded by the Company under the lease are treated as lease incentives which reduce revenue recognized over the term of the lease. The Company considers a number of different factors to evaluate whether it or the lessee is the owner of the tenant improvements for accounting purposes. Rental income is recognized on a straight-line basis over the term of each lease. The difference between rental income earned on a straight-line basis and the cash rent due under the provisions of the lease agreements is recorded as deferred rent receivable and is included as a component of accounts and rent receivable on the consolidated balance sheets. Due to the impact of the straight-line basis, rental income generally will be greater than the cash collected in the early years and will decrease in the later years of a lease. Reimbursements from tenants for recoverable real estate tax and operating expenses are accrued as revenue in the period the applicable expenses are incurred. The Company makes certain assumptions and judgments in estimating the reimbursements at the end of each reporting period. The Company does not expect the actual results to materially differ from the estimated reimbursement. The Company made the election for these reimbursements, which are non-lease components, to be combined with rental income. The Company records lease termination income if there is a signed termination agreement, all of the conditions of the agreement have been met and amounts due are considered collectible. Such termination fees are recognized on a straight-line basis over the remaining lease term in rental income. As a lessor, the Company defers the recognition of contingent rental income, such as percentage rent, until the specified target that triggered the contingent rental income is achieved. Equity-Based Compensation The Company has restricted shares and units outstanding at December 31, 2019 and 2018. The Company recognizes expense related to the fair value of equity-based compensation awards as general and administrative expense on the consolidated statements of operations and comprehensive loss. The Company primarily recognizes expense based on the fair value at the grant date on a straight-line basis over the vesting period representing the requisite service period and adjusts expense for forfeitures as they occur. See Note 9 - "Equity-Based Compensation" for further information. Recently Adopted Accounting Pronouncements In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) Leases. As part of its adoption of the lease standard, the Company has elected and qualifies to utilize the practical expedient in ASU No. 2018-11, Targeted Improvements, Leases (Topic 842) The Company also elected the package of practical expedients in ASU No. 2018-11, which permitted the Company to adopt the new leases standard under a transition method whereby it initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Therefore, the Company adopted ASU No. 2016-02 on its effective date without restating comparative periods and utilized the practical expedients available in the amendment as part of its adoption. The package of practical expedients included relief from re-assessing a lease using the standard’s new definition of a lease, relief from re-assessing the classification of a lease and allowing previously capitalized initial direct costs (see above) to continue to be amortized. The adoption of the package of practical expedients, as a lessor, did not require the Company to recognize a cumulative effect adjustment. For lessees, ASU No. 2016-02 establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. The Company is the lessee of a ground lease. The Company has elected the practical expedient that, for leases that commenced before the effective date, the lessee need not reassess whether the contract is a lease nor reassess lease classification for existing leases. The lease liability for the ground lease was based on the present value of the ground lease’s future lease payments using an interest rate which it considers reasonable and within the range of the Company’s incremental borrowing rate. At January 1, 2019, the Company recorded a lease liability of $23,377 and a ROU asset of $15,963 on its consolidated balance sheet. Rental expense for lease payments related to the operating lease will continue to be recognized on a straight-line basis over the lease term.

Equity [Abstract]
Equity	NOTE 3 – EQUITY The Company commenced an initial public “best efforts” offering (the “Offering”) on October 18, 2012, which concluded on October 16, 2015. The Company sold 33,534,022 shares of common stock generating gross proceeds of $834,399 from the Offering. On March 3, 2020, the Company’s board of directors determined an estimated per share NAV of the Company’s common stock as of December 31, 2019. The previously estimated per share NAV of the Company’s common stock as of December 31, 2018 was established on March 5, 2019. The Company provides the following programs to facilitate additional investment in the Company’s shares and to provide limited liquidity for stockholders. Distribution Reinvestment Plan On October 19, 2015, the Company registered 25,000,000 shares of common stock to be issued under its distribution reinvestment plan (“DRP”) pursuant to a registration statement on Form S-3D. The Company provides stockholders with the option to purchase additional shares from the Company by automatically reinvesting cash distributions through the DRP, subject to certain share ownership restrictions. The Company does not pay any selling commissions or a marketing contribution and due diligence expense allowance in connection with the DRP. Pursuant to the DRP, the price per share for shares of common stock purchased under the DRP is equal to the estimated value of a share, as determined by the Company’s board of directors and reported by the Company from time to time, until the shares become listed for trading, if a listing occurs, assuming that the DRP has not been terminated or suspended in connection with such listing. Distributions reinvested through the DRP were $19,642, $19,339 and $27,069 for the years ended December 31, 2019, 2018 and 2017, respectively. Share Repurchase Program The Company adopted a share repurchase program (as amended, “SRP”) effective October 18, 2012, under which the Company is authorized to purchase shares from stockholders who purchased their shares from the Company or received their shares through a non-cash transfer and who have held their shares for at least one year. Purchases are in the Company’s sole discretion. In the case of repurchases made upon the death of a stockholder or qualifying disability (“Exceptional Repurchases”), as defined in the SRP, the one year holding period does not apply. The SRP was amended and restated effective January 1, 2018 to change the processing of repurchase requests from a monthly to a quarterly basis to align with the move to quarterly distributions. On February 11, 2019, the Company’s board of directors adopted a second amended and restated SRP, effective March 21, 2019. On March 3, 2020 the Company’s board of directors adopted the Third A&R SRP. Under the Third A&R SRP, the Company is authorized to make ordinary repurchases and Exceptional Repurchases at a price equal to 80.0% of the “share price,” which is defined in the Third A&R SRP as an amount equal to the lesser of: (A) $25, as adjusted under certain circumstances, including, among other things, if the applicable shares were purchased from the Company at a discounted price; or (B) the most recently disclosed estimated value per share. Prior to the amendment, the Company was authorized to make Exceptional Repurchases at a price equal to 100% of the “share price.” The Third A&R SRP provides the Company’s board of directors with the discretion to reduce the funding limit for share repurchases. The Third A&R SRP limits the dollar amount for any repurchases made by the Company each calendar quarter to an amount equal to a percentage determined in the sole discretion of the board on a quarterly basis that will not be less than 50% of the net proceeds from the DRP during the applicable quarter. The Company continues to limit the number of shares repurchased during any calendar year to 5% of the number of shares outstanding on December 31st of the previous calendar year, as adjusted for any stock splits or other combinations. If either or both of the repurchase limitations prevent the Company from repurchasing all of the shares offered for repurchase during a calendar quarter, the Company will repurchase shares, on a pro rata basis within each category below, in accordance with the repurchase limitations in the following order: (a) first, all Exceptional Repurchases and (b) second, all ordinary repurchases. The SRP will immediately terminate if the Company’s shares become listed for trading on a national securities exchange. Repurchases through the SRP were $9,381, $22,545 and $21,066 for the years ended December 31, 2019, 2018 and 2017, respectively. At December 31, 2019 and 2018, the liability related to the SRP was $2,278 and $5,463, respectively, recorded in other liabilities on the Company’s consolidated balance sheets.

Investment In And Notes Receivable From Unconsolidated Entities [Abstract]
Investment in and Notes Receivable from Unconsolidated Entities	NOTE 6 – INVESTMENT IN AND NOTES RECEIVABLE FROM UNCONSOLIDATED ENTITIES In August 2017, the Company, through a wholly owned taxable REIT subsidiary, made an equity commitment to Mainstreet JV to develop, construct, lease, finance and sell parcels of land and related building improvements including personal property which were to be operated as rapid recovery healthcare facilities located in Beaumont, Amarillo and Temple, Texas. In conjunction with its equity investment in Mainstreet JV, the Company also agreed to provide subsidiaries of Mainstreet JV mezzanine loans in the aggregate amount of $5,400. The loan term was for 48 months with the Company earning interest at a rate of 14.5% per annum and receiving monthly interest payments based on a 10.5% pay rate. The remaining unpaid interest was to be due at maturity or upon certain defined events. The mezzanine loans were guaranteed by one of the other members of the joint venture. The borrowers could draw on the mezzanine loans as needed in connection with the construction of the rapid recovery healthcare facilities, however, did not draw on the mezzanine loans until the Company had fully funded its equity commitment to Mainstreet JV. As of December 31, 2017, the Company had not loaned any funds related to the mezzanine loans. During 2018, the Company funded its remaining equity commitment to Mainstreet JV, as well as the full $5,400 of mezzanine loans. Subsequently, during 2018, the Company identified several indicators that suggested it was probable that the Company would not recover its equity investment in or the mezzanine loans advanced to Mainstreet JV. Such indicators included construction overruns, loss of a planned tenant and the related cost of re-leasing. Additionally, the construction mortgage lender to Mainstreet JV stopped funding the construction draws for two of the properties and began foreclosure proceedings. As the Company does not intend to fund any more investments in Mainstreet JV and it does not expect to recover any of its previous investments, the Company determined an impairment for both its investment in and notes receivable from Mainstreet JV is appropriate. During the year ended December 31, 2018, the Company recorded an impairment to its investment in Mainstreet JV of $9,865 and an impairment to its notes receivable from unconsolidated entities of $5,540, both included in provision for impairment of investment in and note receivable from unconsolidated entities on the consolidated statement of operations and comprehensive loss. Both amounts represent a full impairment of such investments.

For below market lease values, the amortization period includes any renewal periods with fixed rate renewals. Prior to January 1, 2019, the acquired above market ground lease was amortized on a straight-line basis as an adjustment to property operating expense over the term of the lease and included renewal periods. At date of the adoption of ASC 842 on January 1, 2019, the remaining balance of the intangible related to the above market ground lease was derecognized as a cumulative-effect adjustment to establish the operating lease ROU asset. The portion of the purchase price allocated to acquired in-place lease value is amortized on a straight-line basis over the acquired leases’ weighted average remaining term. Amortization pertaining to acquired in-place lease value, above market ground lease, above market lease value and below market lease value is summarized below: Amortization recorded as amortization expense: 2019 2018 2017 Acquired in-place lease value $ 17,841 $ 19,410 $ 22,104 Amortization recorded as a reduction to property operating expense: Above market ground lease $ — $ 94 $ 94 Amortization recorded as a (reduction) increase to rental income: Acquired above market leases $ (3,502 ) $ (3,891 ) $ (4,379 ) Acquired below market leases 4,907 4,714 5,700 Net rental income increase $ 1,405 $ 823 $ 1,321 Estimated amortization of the respective intangible lease assets and liabilities as of December 31, 2019 for each of the five succeeding years and thereafter is as follows: Acquired In-Place Leases Above Market Leases Below Market Leases 2020 $ 12,953 $ 3,020 $ (3,896 ) 2021 10,539 2,953 (3,715 ) 2022 7,900 2,664 (3,482 ) 2023 6,673 2,477 (3,224 ) 2024 5,667 2,308 (3,047 ) Thereafter 18,703 13,495 (29,456 ) Total $ 62,435 $ 26,917 $ (46,820 )

At December 31, 2019, the Company had $117,022 outstanding under the Revolving Credit Facility and $150,000 outstanding under the Term Loan. At December 31, 2019 the interest rate on the Revolving Credit Facility and the Term Loan was 3.45% and 4.29%, respectively. The Revolving Credit Facility matures on August 1, 2022, and the Company has the option to extend the maturity date for one additional year subject to the payment of an extension fee and certain other conditions. The Term Loan matures on August 1, 2023. As of December 31, 2019 the Company had $82,978 available for borrowing under the Revolving Credit Facility. The Company’s performance of the obligations under the Credit Facility, including the payment of any outstanding indebtedness under the Credit Facility, is guaranteed by certain subsidiaries of the Company, including each of the subsidiaries of the Company which owns or leases any of the properties included in the pool of unencumbered properties comprising the borrowing base. Additional properties will be added to and removed from the pool from time to time to support amounts borrowed under the Credit Facility. At December 31, 2019, there were 28 properties included in the pool of unencumbered properties. During the year ended December 31, 2019, the Company paid-off two mortgage loans with a principal balance of $7,447. The Credit Facility requires compliance with certain covenants, including a minimum tangible net worth requirement, a distribution limitation, restrictions on indebtedness and investment restrictions, as defined. It also contains customary default provisions including the failure to comply with the Company's covenants and the failure to pay when amounts outstanding under the Credit Facility become due. The Company is in compliance with all financial covenants related to the Credit Facility. Gain on early termination of interest rate swap agreements During the year ended December 31, 2018, the Company recorded a net gain of $1,151 of which $1,192 was received in cash, related to the early termination of certain interest rate swap agreements that had corresponding early mortgage pay-offs. Loss on extinguishment of debt During the year ended December 31, 2018, the Company realized a loss on extinguishment of debt on the consolidated statement of operations and comprehensive loss of $411 due to the write-off of the unamortized balance of debt issuance costs associated with ten loans that were repaid prior to maturity. Mortgages Payable The mortgage loans require compliance with certain covenants, such as debt service ratios, investment restrictions and distribution limitations. As of December 31, 2019, the Company was current on all of the payments and in compliance with all financial covenants. All of the Company’s mortgage loans are secured by first mortgages on the respective real estate assets. As of December 31, 2019, the weighted average years to maturity for the Company’s mortgages payable was 3.7 years. Interest Rate Swap Agreements The Company entered into interest rate swaps to fix certain of its floating LIBOR based debt under variable rate loans to a fixed rate to manage its risk exposure to interest rate fluctuations.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Equity-Based Compensation	NOTE 9 – EQUITY-BASED COMPENSATION Under the Company’s Employee and Director Restricted Share Plan (“RSP”), restricted shares and restricted share units generally vest over a one to three year vesting period from the date of the grant, subject to the specific terms of the grant. On June 4, 2019, we issued 2,237 restricted shares and 746 restricted share units to our independent directors pursuant to the automatic grant provisions of the RSP, which become vested in equal installments of 33-1/3% on each of the first three anniversaries of June 4, 2019, subject to certain exceptions. In accordance with the RSP, restricted shares and restricted share units were issued to non-employee directors as compensation. Each restricted share and restricted share unit entitles the holder to receive one common share when it vests. Restricted shares and restricted share units are included in common stock outstanding on the date of the vesting. The grant-date value of the restricted shares and restricted share units is amortized over the vesting period representing the requisite service period. Compensation expense associated with the restricted shares and restricted share units issued to the non-employee directors was $53, $48 and $33 in the aggregate, for the year ended December 31, 2019, 2018 and 2017, respectively. As of December 31, 2019, the Company had $55 of unrecognized compensation expense related to the unvested restricted shares and restricted share units, in the aggregate. The weighted average remaining period that compensation expense related to unvested restricted shares and restricted share units will be recognized is 1.5 years. The total fair value at the vesting date for restricted shares and restricted share units that vested during the years ended December 31, 2019, 2018 and 2017 was $43, $30 and $14, respectively. A summary of the Company’s restricted share and restricted share unit activity during the years ended December 31, 2019, 2018 and 2017 is as follows: Restricted Shares Restricted Share Units Outstanding at December 31, 2016 1,330 460 Granted (at grant date fair value of $22.63 per share) 1,657 600 Vested (444 ) (156 ) Outstanding at December 31, 2017 2,543 904 Granted (at grant date fair value of $22.35 per share) 1,677 650 Vested (996 ) (353 ) Outstanding at December 31, 2018 3,224 1,201 Granted (at grant date fair value of $20.12 per share) 2,237 849 Vested (1,555 ) (570 ) Outstanding at December 31, 2019 3,906 1,480

Income Tax And Distributions [Abstract]
Income Tax and Distributions	NOTE 10 – INCOME TAX AND DISTRIBUTIONS The Company qualifies as a REIT under the Internal Revenue Code of 1986, as amended, for federal income tax purposes. In order to maintain the Company’s status as a REIT, the Company must annually distribute at least 90% of its REIT taxable income, subject to certain adjustments and excluding any net capital gain, to its stockholders. For the years ended December 31, 2019, 2018 and 2017, the Company’s REIT taxable income was $988 (unaudited), $9,073 (unaudited) . The Company had no uncertain tax positions as of December 31, 2019 or 2018. The Company expects no significant increases or decreases in uncertain tax positions due to changes in tax positions within one year of December 31, 2019. The Company had no interest or penalties relating to income taxes recognized on the consolidated statements of operations and comprehensive loss for the years ended December 31, 2019, 2018 or 2017. As of December 31, 2019, returns for the calendar years 2016, 2017, 2018 and 2019 remain subject to examination by U.S. and various state and local tax jurisdictions. As a result of the $15,405 impairment for the Mainstreet JV recorded on the Company’s consolidated statement of operations and comprehensive loss during the year ended December 31, 2018, the Company will likely recognize either a capital or net operating loss or a combination thereof, for income tax purposes, from this venture in the future. The Company’s investment in Mainstreet JV is held through a taxable REIT subsidiary. Based on an effective tax rate of 28.51%, which is calculated by combining a 21% Federal tax rate and an IL tax rate of 7.51% (9.5% state rate net of the Federal benefit), the deferred tax benefit related to the impairment is approximately $4,400. Since the taxable REIT subsidiary does not currently conduct any activities outside the investment in Mainstreet JV, management does not believe it is more likely than not that the taxable REIT subsidiary will be able to utilize these losses in future tax periods. As a result, management recorded a full valuation allowance of $4,400 to account for this uncertainty during the year ended December 31, 2018. No income tax expense or benefit was recorded during the years ended December 31, 2019, 2018 or 2017. Distributions In 2019, the Company paid quarterly distributions in an amount equal to $0.3018 per share, which represented an annualized rate of 6% based on the previously estimated per share NAV as of December 31, 2018, payable in arrears the following quarter. In 2018, the Company paid quarterly distributions in an amount equal to $0.335 per share, which represented an annualized rate of 6% based on the previously estimated per share NAV as of December 31, 2017, payable in arrears the following quarter. The Company paid distributions based on daily record dates, payable in arrears the following month, equal to a daily amount of $0.00410959 per share, based upon a 365-day period for 2017. The table below presents the distributions paid and declared for the years ended December 31, 2019, 2018 and 2017. The table below presents the distributions paid and declared for the years ended December 31, 2019, 2018 and 2017.

Distributions to the extent of the Company’s current and accumulated earnings and profits for federal income tax purposes are taxable to the recipient as either ordinary dividend income or, if so declared by the Company, qualified dividend income or capital gain dividends. Distributions in excess of these earnings and profits (calculated for income tax purposes) constitute a non-taxable return of capital rather than ordinary dividend income or a capital gain dividend and reduce the recipient’s tax basis in the shares to the extent thereof.

Earnings Per Share [Abstract]
Earnings (Loss) per Share	NOTE 11 – EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share (“EPS”) is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period (the “common shares”). Diluted EPS is computed by dividing net income (loss) by the common shares plus common share equivalents. The Company excludes antidilutive restricted shares and units from the calculation of weighted-average shares for diluted EPS. As a result of a net loss for the years ended December 31, 2019, 2018 and 2017, 2,902 shares, 2,625 shares and 1,507 shares, respectively, were excluded from the computations of diluted EPS, because they would have been antidilutive.

(b) Prior to February 11, 2019, the Company was required to pay the Business Manager or its affiliates a fee equal to 1.5% of the “contract purchase price,” as defined, of each asset acquired. The business management agreement was amended and restated to, among other things, remove the obligation to pay acquisition fees and disposition fees payable to the Business Manager by the Company with respect to transactions occurring on or after February 11, 2019. The Business Manager and its related parties continue to be reimbursed for acquisition and transaction related costs of the Business Manager and its related parties relating to the Company’s acquisition activities, regardless of whether the Company acquires the real estate assets. There were no related party acquisition costs or fees incurred during the year ended December 31, 2019. Of the $36 related party acquisition costs and fees incurred during the year ended December 31, 2018, $12 are capitalized as the acquisition of net investment properties on the consolidated balance sheet. Of the $1,540 related party acquisition costs incurred during the year ended December 31, 2017, $1,260 are capitalized as the acquisition of net investment properties on the consolidated balance sheet, $134 are capitalized as investment in unconsolidated entities on the consolidated balance sheet, and $146 of such costs are included in acquisition related costs on the consolidated statement of operations and comprehensive loss.

The Real Estate Manager determines, in its sole discretion, the amount of the fee with respect to a particular property, subject to the limitations. For each property that is managed directly by the Real Estate Manager or its affiliates, the Company pays the Real Estate Manager a separate leasing fee. Further, in the event that the Company engages its Real Estate Manager to provide construction management services for a property, the Company pays a separate construction management fee. Leasing fees are included in deferred costs, net and construction management fees are included in building and other improvements on the consolidated balance sheets. The Company also reimburses the Real Estate Manager and its affiliates for property-level expenses that they pay or incur on the Company’s behalf, including the salaries, bonuses and benefits of persons performing services for the Real Estate Manager and its affiliates except for the salaries, bonuses and benefits of persons who also serve as an executive officer of the Real Estate Manager or the Company.

Leases

Leases	12 Months Ended
	Dec. 31, 2019
Leases [Abstract]
Leases	NOTE 15 –LEASES The Company is lessor on over 700 retail operating leases. The remaining lease terms for the Company’s leases range from less than one year to 17 years. The Company considers the date on which it makes a leased space available to a lessee as the commencement date of the lease. At commencement, the Company determines the lease classification utilizing the classification tests under ASC 842. Options to extend a lease are included in the lease term when it is reasonably certain that the tenant will exercise its option to extend. Termination penalties are included in income when there is a termination agreement, all the conditions of the agreement have been met and amounts due are considered collectible. Such termination fees are recognized on a straight-line basis over the remaining lease term in rental income. If an operating lease is modified and the modification is not accounted for as a separate contract, the Company accounts for the modification as if it were a termination of the existing lease and the creation of a new lease. The Company considers any prepaid or accrued rentals relating to the original lease as part of the lease payments for the modified lease. The Company includes options to modify the original lease term when it is reasonably certain that the tenant will exercise its option to extend. Lease Income Most of the revenue from the Company’s properties consists of rents received under long-term operating leases. Most leases require the tenant to pay fixed base rent paid monthly in advance, and to reimburse the Company for the tenant’s pro rata share of certain operating expenses including real estate taxes, special assessments, insurance, utilities, common area maintenance, management fees, and certain building repairs paid by the Company and recoverable under the terms of the lease. Under these leases, the Company pays all expenses and is reimbursed by the tenant for the tenant’s pro rata share of recoverable expenses paid. Certain other tenants are subject to net leases which provide that the tenant is responsible for fixed base rent as well as all costs and expenses associated with occupancy. Under net leases where all expenses are paid directly by the tenant rather than the landlord, such expenses are not included on the consolidated statements of operations and comprehensive loss. Under leases where all expenses are paid by the Company, subject to reimbursement by the tenant, the expenses are included within property operating expenses. As of January 1, 2019, the date on which the Company adopted the new leasing standard, reimbursements for common area maintenance are considered non-lease components that are permitted to be combined with rental income. The combined lease component and reimbursements for insurance and taxes are reported as rental income on the consolidated statements of operations and comprehensive loss. Rental income related to the Company's operating leases is comprised of the following for the year ended December 31, 2019: Rental income - fixed payments $ 101,689 Rental income - variable payments (a) 25,560 Amortization of acquired market leases, net 1,405 Rental income $ 128,654 (a) Primarily includes tenant recovery income for real estate taxes, common area maintenance and insurance. The future base rent payments to be received under operating leases including ground leases as of December 31, 2019 for the years indicated, assuming no expiring leases are renewed, are as follows: Lease Payments 2020 $ 87,909 2021 83,722 2022 73,953 2023 62,374 2024 49,684 Thereafter 148,313 Total $ 505,955 Lease Expense The Company is the lessee under one ground lease. The ground lease, which commenced on July 1, 2007, was assumed as part of a property purchased in October 2015 and extends through June 30, 2037 with six 5-year renewal options which the Company assumes will be exercised. When the Company acquired the lease, the Company considered the lease terms and lease classification. As reassessment is not required under practical expedients accorded in ASC 842, the Company will continue to account for the ground lease as an operating lease with an established lease term and payment schedule. At January 1, 2019, the Company recorded a lease liability of $23,377 and a ROU asset of $15,963 on its consolidated balance sheet. The lease liability was based on the present value of the ground lease’s future lease payments using an interest rate of 6.225% which the Company considers reasonable and within the range of the Company’s incremental borrowing rate. For the years ended December 31, 2019, 2018 and 2017, total rent expense was $1,944, $1,891 and $1,891, respectively, recorded in property operating expenses on the consolidated statements of operations and comprehensive loss . Lease payments for the ground lease as of December 31, 2019 for each of the five succeeding years and thereafter is as follows: Lease Payments 2020 $ 1,140 2021 1,140 2022 1,202 2023 1,264 2024 1,264 Thereafter 87,112 Total $ 93,122

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 16 – FAIR VALUE MEASUREMENTS Fair Value Hierarchy The Company defines fair value based on the price that it believes would be received upon sale of an asset or the exit price that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value. The fair value hierarchy consists of three broad levels, which are described below: Level 1 − Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access. Level 2 − Observable inputs, other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 − Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The Company has estimated the fair value of its financial and non-financial instruments using available market information and valuation methodologies the Company believes to be appropriate for these purposes. Recurring Fair Value Measurements For assets and liabilities measured at fair value on a recurring basis, the table below presents the fair value of the Company’s cash flow hedges as well as their classification on the consolidated balance sheets as of December 31, 2019 and 2018, respectively. Fair Value Level 1 Level 2 Level 3 Total December 31, 2019 Interest rate swap agreements - Other assets $ — $ 715 $ — $ 715 Interest rate swap agreements - Other liabilities $ — $ 7,622 $ — $ 7,622 December 31, 2018 Interest rate swap agreements - Other assets $ — $ 7,286 $ — $ 7,286 Interest rate swap agreements - Other liabilities $ — $ 1,926 $ — $ 1,926 The fair value of derivative instruments was estimated based on data observed in the forward yield curve which is widely observed in the marketplace. The Company also incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the counterparty's nonperformance risk in the fair value measurements which utilize Level 3 inputs, such as estimates of current credit spreads. The Company has determined that the credit valuation adjustments are not significant to the overall valuation of its derivative interest rate swap agreements and therefore has classified these in Level 2 of the hierarchy. Non-recurring Fair Value Measurements As of December 31, 2019, the Company reviewed the carrying value of three investment properties that met held for sale criteria. The criteria was met for these properties because, amongst other criteria, the Company had collected non-refundable earnest money from the seller. Properties classified as held for sale must be recorded at the lesser of their carrying value or the fair value as of the balance sheet date less selling costs in accordance with GAAP. The fair value of these investment properties, classified as Level 2 of the fair value hierarchy, was estimated based on the signed purchase and sale agreements with the seller. All of these properties had a carrying value that exceeded the fair value less selling costs, and therefore, for the year ended December 31, 2019 an impairment loss totaling $4,420 was recorded in provision for asset impairment on the consolidated statement of operations and comprehensive loss. The Company completed the sale of these properties in January 2020. During the year ended December 31, 2018, the Company incurred no impairment charges for investment properties or any other non-recurring fair value measurements. For discussion of full impairment reserve recorded for the Company’s investment in the Mainstreet JV and the related notes receivable, please refer to Note 6 – “Investment In and Notes Receivable from Unconsolidated Entities”. As of December 31, 2017, the Company identified indicators of impairment at one of its investment properties. Such indicators included a low occupancy rate, difficulty in leasing space, declining market rents and the related cost of re-leasing. The fair value of this investment property, classified as Level 3 in the fair value hierarchy, was estimated using the 10-year discounted cash flow model, w hich included estimated inflows and outflows over a specific holding period and estimated net disposition proceeds at the end of the 10-year period

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
General	General The consolidated financial statements have been prepared in accordance with U.S. GAAP and require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. In the opinion of management, all adjustments necessary for a fair statement, in all material respects, of the financial position and results of operations for the periods are presented. Actual results could differ from those estimates. Information with respect to square footage and occupancy is unaudited. Certain amounts in the prior period consolidated financial statements have been reclassified to conform with the current year presentation.
Consolidation	Consolidation The consolidated financial statements include the accounts of the Company, as well as all wholly owned subsidiaries. Wholly owned subsidiaries generally consist of limited liability companies (“LLCs”). All intercompany balances and transactions have been eliminated in consolidation. Each property is owned by a separate legal entity which maintains its own books and financial records and each entity’s assets are not available to satisfy the liabilities of other affiliated entities. The fiscal year-end of the Company is December 31.
Partially-Owned Entities	Partially-Owned Entities The Company will consolidate the operations of a joint venture if the Company determines that it is either the primary beneficiary of a variable interest entity (VIE) or has substantial influence and control of the entity. In instances where the Company determines that it is not the primary beneficiary of a VIE or the Company does not control the joint venture but can exercise influence over the entity with respect to its operations and major decisions, the Company will use the equity method of accounting. Under the equity method, the operations of a joint venture will not be consolidated with the Company’s operations but instead its share of operations will be reflected as equity in earnings (loss) of unconsolidated entity on its consolidated statements of operations and comprehensive loss. Additionally, the Company’s net investment in the joint venture will be reflected as investment in unconsolidated entity on the consolidated balance sheets.
Acquisitions	Acquisitions Upon acquisition of real estate investment properties, the Company allocates the total purchase price of each property that is accounted for as an asset acquisition based on the relative fair value of the tangible and intangible assets acquired and liabilities assumed based on Level 3 inputs, such as comparable sales values, discount rates, capitalization rates, revenue and expense growth rates and lease-up assumptions, from a third party appraisal or other market sources. The acquisition date is the date on which the Company obtains control of the real estate investment property and transaction costs are capitalized. Assets and liabilities acquired typically include land, building and site improvements and identified intangible assets and liabilities, consisting of the value of above market and below market leases and the value of in-place leases. The portion of the purchase price allocated to above market lease values is included in acquired lease intangible assets, net and is amortized on a straight-line basis over the term of the related lease as a reduction to rental income. The portion allocated to below market lease values is included in acquired intangible liabilities, net and is amortized as an increase to rental income over the term of the lease including any renewal periods with fixed rate renewals. The portion of the purchase price allocated to acquired in-place lease value is included in acquired lease intangible assets, net and is amortized on a straight-line basis over the acquired leases’ weighted average remaining term. The Company determines the fair value of the tangible assets consisting of land and buildings by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land and buildings. The Company determines the fair value of assumed debt by calculating the net present value of the mortgage payments using interest rates for debt with similar terms and maturities. Differences between the fair value and the stated value is recorded as a discount or premium and amortized over the remaining term using the effective interest method. Certain of the Company’s properties included earnout components to the purchase price, meaning the Company did not pay a portion of the purchase price of the property at closing, although the Company owns the entire property. The Company is not obligated to settle the contingent portion of the purchase price unless space which was vacant at the time of acquisition is later leased by the seller within the time limits and parameters set forth in the related acquisition agreements. The Company’s policy is to record earnout components when estimable and probable. At December 31, 2019, there is no earnout liability outstanding.
Impairment of Investment Properties and Equity Method Investments	Impairment of Investment Properties and Equity Method Investments The Company assesses the carrying values of its respective long-lived assets whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. Recoverability of the assets is measured by comparison of the carrying amount of the asset to the estimated future undiscounted cash flows. In order to review its assets for recoverability, the Company considers current market conditions, as well as its intent with respect to holding or disposing of the asset. If the Company’s analysis indicates that the carrying value of the long-lived asset is not recoverable on an undiscounted cash flow basis, the Company recognizes an impairment charge for the amount by which the carrying value exceeds the current estimated fair value of the real estate property. Fair value is determined through various valuation techniques, including discounted cash flow models, quoted market values and third party appraisals, where considered necessary (Level 3 inputs). The Company estimates the future undiscounted cash flows based on management’s intent as follows: (i) for real estate properties that the Company intends to hold long-term, including land held for development, properties currently under development and operating buildings, recoverability is assessed based on the estimated future net rental income from operating the property and termination value; and (ii) for real estate properties that the Company intends to sell, including land parcels, properties currently under development and operating buildings, recoverability is assessed based on estimated net proceeds, including net rental income during the holding period, from disposition that are estimated based on future net rental income of the property and utilizing expected market capitalization rates. The use of projected future cash flows is based on assumptions that are consistent with our estimates of future expectations and the strategic plan the Company uses to manage its underlying business. However, assumptions and estimates about future cash flows, including comparable sales values, discount rates, capitalization rates, revenue and expense growth rates and lease-up assumptions which impact the discounted cash flow approach to determining value are complex and subjective. Changes in economic and operating conditions and the Company’s ultimate investment intent that occur subsequent to the impairment analysis could impact these assumptions and result in future impairment charges of real estate properties. On a quarterly basis, management assesses whether there are any indicators that the carrying value of the Company’s investment in unconsolidated entities and notes receivable may be other than temporarily impaired as a loss in value that is other than a temporary decline is required to be recognized. Indicators include significant delays in construction, significant costs over budget and financial concerns. To the extent indicators suggest that a loss in value may have occurred, the Company will evaluate both quantitative and qualitative factors to determine if the loss in value is other than temporary. If a potential loss in value is determined to be other than temporary, the Company will recognize an impairment loss based on the estimated fair value of the investment. During the year ended December 31, 2019, the Company recorded an impairment charge of $4,420 which is included in provision for asset impairment on the consolidated statement of operations and comprehensive loss. During the year ended December 31, 2018, the Company recorded an impairment charge of $9,865 related to its investment in Mainstreet Texas Development Fund, LLC, a joint venture formed to develop three transitional care/rapid recovery centers (“Mainstreet JV”). The Company determined that, as of December 31, 2018, collection of its note receivable from Mainstreet JV is improbable and therefore, recorded an impairment charge of $5,540 to reduce the note receivable balance to zero. Both impairment charges related to Mainstreet JV are included in provision for impairment of investment in and note receivable from unconsolidated entities on the consolidated statement of operations and comprehensive loss. During the year ended December 31, 2017, the Company recorded an impairment charge of $8,530 which is included in provision for asset impairment on the consolidated statement of operations and comprehensive loss.
REIT Status	REIT Status The Company elected to be taxed as a real estate investment trust (“REIT”) under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended, for federal income tax purposes commencing with the tax year ended December 31, 2013. Commencing with such taxable year, the Company was organized and began operating in such a manner as to qualify for taxation as a REIT under the Internal Revenue Code and believes it has so qualified. As a result, the Company generally will not be subject to federal income tax on taxable income that is distributed to stockholders. A REIT is subject to a number of organizational and operational requirements, including a requirement that it currently distributes at least 90% of its REIT taxable income (subject to certain adjustments and excluding any net capital gain) to its stockholders. The Company will monitor the business and transactions that may potentially impact its REIT status. If the Company fails to qualify as a REIT in any taxable year, without the benefit of certain statutory relief provisions, the Company will be subject to tax as a “C corporation.” Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income, property or net worth and federal income and excise taxes. Any taxable REIT subsidiaries generally will be subject to federal income tax applicable to “C corporations.”
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all demand deposits, money market accounts and all short-term investments with a maturity of three months or less, at the date of purchase, to be cash equivalents. The account balance may exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there could be a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company believes that the risk will not be significant, as the Company does not anticipate the financial institutions’ non-performance.
Restricted Cash	Restricted Cash Amounts included in restricted cash represent those required to be set aside by lenders for real estate taxes, insurance, capital expenditures and tenant improvements on our existing properties. These amounts also include post close escrows for tenant improvements, leasing commissions, master lease, general repairs and maintenance, and are classified as restricted cash on the Company’s consolidated balance sheets. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported on the Company’s consolidated balance sheets to such amounts shown on the Company’s consolidated statements of cash flows: December 31, 2019 2018 Cash and cash equivalents $ 4,516 $ 15,239 Restricted cash 1,017 1,001 Total cash, cash equivalents, and restricted cash $ 5,533 $ 16,240
Accounts and Rents Receivable	Accounts and Rents Receivable The Company takes into consideration certain factors that require judgments to be made as to the collectability of receivables. Collectability factors taken into consideration are the amounts outstanding and payment history of the tenant. The Company includes both billed and accrued charges in its evaluation of the collectability of a tenant’s receivable balance. For tenant receivables that the Company determines to be uncollectible, the Company records an offset for uncollectable tenant revenues directly to rental income.
Capitalization and Depreciation	Capitalization and Depreciation Real estate properties held and used are recorded at cost less accumulated depreciation. Real estate properties held for sale are recorded at the lesser of their carrying value or fair value less selling costs. Improvement and betterment costs are capitalized, and ordinary repairs and maintenance are expensed as incurred. Real estate properties are classified as held for sale when the Company concludes that a sale is likely. Criteria that may be considered in this determination include obtaining a signed purchase and sale agreement, the completion and waiving of due diligence by the seller, and the receipt of non-refundable earnest money from the seller. Cost capitalization and the estimate of useful lives require judgment and include significant estimates that can and do change. Depreciation expense is computed using the straight-line method. The Company anticipates the estimated useful lives of its assets by class to be generally: Building and other improvements 30 years Site improvements 5-15 years Furniture, fixtures and equipment 5-15 years Tenant improvements Shorter of the life of the asset or the term of the related lease Leasing fees Term of the related lease Depreciation expense was $39,304, $38,040 and $39,497 for the years ended December 31, 2019, 2018 and 2017, respectively. Amortization of leasing fees were $546, $360, and $168 for the years ended December 31, 2019, 2018 and 2017, respectively.
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs are amortized on a straight-line basis, which approximates the effective interest method, over the term, or anticipated repayment date, of the related agreements as a component of interest expense. These costs are reported as a direct deduction to the Company’s outstanding mortgages and credit facility payable.
Fair Value Measurements	Fair Value Measurements The Company has estimated fair value using available market information and valuation methodologies the Company believes to be appropriate for these purposes. Considerable judgment and a high degree of subjectivity are involved in developing these estimates and, accordingly, they are not necessarily indicative of amounts that would be realized upon disposition. The Company defines fair value based on the price that it believes would be received upon sale of an asset or the exit price that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value. The fair value hierarchy consists of three broad levels, which are described below: Level 1 − Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access. Level 2 − Observable inputs, other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 − Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The Company’s cash equivalents, accounts receivable and payables and accrued expenses all approximate fair value due to the short term nature of these financial instruments. The Company’s financial instruments measured on a recurring basis include derivative interest rate instruments.
Derivatives	Derivatives The Company uses derivative instruments, such as interest rate swaps, primarily to manage exposure to interest rate risks inherent in variable rate debt. The Company may also enter into forward starting swaps or treasury lock agreements to set the effective interest rate on a planned fixed-rate financing. The Company’s interest rate swaps involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. In a forward starting swap or treasury lock agreement that the Company cash settles in anticipation of a fixed rate financing or refinancing, the Company will receive or pay an amount equal to the present value of future cash flow payments based on the difference between the contract rate and market rate on the settlement date. The Company does not use derivatives for trading or speculative purposes and currently does not have any derivatives that are not designated as hedging instruments under the accounting requirements for derivatives and hedging.
Revenue Recognition	Revenue Recognition The Company commences revenue recognition for its operating leases on the commencement date of the lease, which the Company considers is the date on which it makes the leased space available to the lessee. The determination of who is the owner, for accounting purposes, of the tenant improvements determines the nature of the leased asset. If the Company is the owner, for accounting purposes, of the tenant improvements, then the tenant improvements are capitalized and depreciated over the life of the lease. If the Company concludes it is not the owner, for accounting purposes, of the tenant improvements (the lessee is the owner), then the leased asset is the unimproved space and any tenant improvement allowances funded by the Company under the lease are treated as lease incentives which reduce revenue recognized over the term of the lease. The Company considers a number of different factors to evaluate whether it or the lessee is the owner of the tenant improvements for accounting purposes. Rental income is recognized on a straight-line basis over the term of each lease. The difference between rental income earned on a straight-line basis and the cash rent due under the provisions of the lease agreements is recorded as deferred rent receivable and is included as a component of accounts and rent receivable on the consolidated balance sheets. Due to the impact of the straight-line basis, rental income generally will be greater than the cash collected in the early years and will decrease in the later years of a lease. Reimbursements from tenants for recoverable real estate tax and operating expenses are accrued as revenue in the period the applicable expenses are incurred. The Company makes certain assumptions and judgments in estimating the reimbursements at the end of each reporting period. The Company does not expect the actual results to materially differ from the estimated reimbursement. The Company made the election for these reimbursements, which are non-lease components, to be combined with rental income. The Company records lease termination income if there is a signed termination agreement, all of the conditions of the agreement have been met and amounts due are considered collectible. Such termination fees are recognized on a straight-line basis over the remaining lease term in rental income. As a lessor, the Company defers the recognition of contingent rental income, such as percentage rent, until the specified target that triggered the contingent rental income is achieved.
Equity-Based Compensation	Equity-Based Compensation The Company has restricted shares and units outstanding at December 31, 2019 and 2018. The Company recognizes expense related to the fair value of equity-based compensation awards as general and administrative expense on the consolidated statements of operations and comprehensive loss. The Company primarily recognizes expense based on the fair value at the grant date on a straight-line basis over the vesting period representing the requisite service period and adjusts expense for forfeitures as they occur. See Note 9 - "Equity-Based Compensation" for further information.
Recently Adopted Accounting and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) Leases. As part of its adoption of the lease standard, the Company has elected and qualifies to utilize the practical expedient in ASU No. 2018-11, Targeted Improvements, Leases (Topic 842) The Company also elected the package of practical expedients in ASU No. 2018-11, which permitted the Company to adopt the new leases standard under a transition method whereby it initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Therefore, the Company adopted ASU No. 2016-02 on its effective date without restating comparative periods and utilized the practical expedients available in the amendment as part of its adoption. The package of practical expedients included relief from re-assessing a lease using the standard’s new definition of a lease, relief from re-assessing the classification of a lease and allowing previously capitalized initial direct costs (see above) to continue to be amortized. The adoption of the package of practical expedients, as a lessor, did not require the Company to recognize a cumulative effect adjustment. For lessees, ASU No. 2016-02 establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. The Company is the lessee of a ground lease. The Company has elected the practical expedient that, for leases that commenced before the effective date, the lessee need not reassess whether the contract is a lease nor reassess lease classification for existing leases. The lease liability for the ground lease was based on the present value of the ground lease’s future lease payments using an interest rate which it considers reasonable and within the range of the Company’s incremental borrowing rate. At January 1, 2019, the Company recorded a lease liability of $23,377 and a ROU asset of $15,963 on its consolidated balance sheet. Rental expense for lease payments related to the operating lease will continue to be recognized on a straight-line basis over the lease term.

Description of share repurchase program	Under the Third A&R SRP, the Company is authorized to make ordinary repurchases and Exceptional Repurchases at a price equal to 80.0% of the “share price,” which is defined in the Third A&R SRP as an amount equal to the lesser of: (A) $25, as adjusted under certain circumstances, including, among other things, if the applicable shares were purchased from the Company at a discounted price; or (B) the most recently disclosed estimated value per share. Prior to the amendment, the Company was authorized to make Exceptional Repurchases at a price equal to 100% of the “share price. The Third A&R SRP provides the Company’s board of directors with the discretion to reduce the funding limit for share repurchases. The Third A&R SRP limits the dollar amount for any repurchases made by the Company each calendar quarter to an amount equal to a percentage determined in the sole discretion of the board on a quarterly basis that will not be less than 50% of the net proceeds from the DRP during the applicable quarter. The Company continues to limit the number of shares repurchased during any calendar year to 5% of the number of shares outstanding on December 31st of the previous calendar year, as adjusted for any stock splits or other combinations. If either or both of the repurchase limitations prevent the Company from repurchasing all of the shares offered for repurchase during a calendar quarter, the Company will repurchase shares, on a pro rata basis within each category below, in accordance with the repurchase limitations in the following order: (a) first, all Exceptional Repurchases and (b) second, all ordinary repurchases.

[1]	The Business Manager and its related parties are entitled to reimbursement for certain general and administrative expenses incurred by the Business Manager and its related parties relating to the Company’s administration. Such costs are included in general and administrative expenses on the consolidated statements of operations and comprehensive loss. Unpaid amounts are included in due to related parties on the consolidated balance sheets.
[2]	Prior to February 11, 2019, the Company was required to pay the Business Manager or its affiliates a fee equal to 1.5% of the “contract purchase price,” as defined, of each asset acquired.  The business management agreement was amended and restated to, among other things, remove the obligation to pay acquisition fees and disposition fees payable to the Business Manager by the Company with respect to transactions occurring on or after February 11, 2019. The Business Manager and its related parties continue to be reimbursed for acquisition and transaction related costs of the Business Manager and its related parties relating to the Company’s acquisition activities, regardless of whether the Company acquires the real estate assets.  There were no related party acquisition costs or fees incurred during the year ended December 31, 2019. Of the $36 related party acquisition costs and fees incurred during the year ended December 31, 2018, $12 are capitalized as the acquisition of net investment properties on the consolidated balance sheet. Of the $1,540 related party acquisition costs incurred during the year ended December 31, 2017, $1,260 are capitalized as the acquisition of net investment properties on the consolidated balance sheet, $134 are capitalized as investment in unconsolidated entities on the consolidated balance sheet, and $146 of such costs are included in acquisition related costs on the consolidated statement of operations and comprehensive loss. Unpaid amounts are included in due to related parties on the consolidated balance sheets.
[3]	For each property that is managed by Inland Commercial Real Estate Services LLC (the “Real Estate Manager”) (and its predecessor), the Company pays a monthly real estate management fee of up to 1.9% of the gross income from any single-tenant, net-leased property, and up to 3.9% of the gross income from any other property type. The Real Estate Manager determines, in its sole discretion, the amount of the fee with respect to a particular property, subject to the limitations. For each property that is managed directly by the Real Estate Manager or its affiliates, the Company pays the Real Estate Manager a separate leasing fee. Further, in the event that the Company engages its Real Estate Manager to provide construction management services for a property, the Company pays a separate construction management fee. Leasing fees are included in deferred costs, net and construction management fees are included in building and other improvements on the consolidated balance sheets. The Company also reimburses the Real Estate Manager and its affiliates for property-level expenses that they pay or incur on the Company’s behalf, including the salaries, bonuses and benefits of persons performing services for the Real Estate Manager and its affiliates except for the salaries, bonuses and benefits of persons who also serve as an executive officer of the Real Estate Manager or the Company. Real estate management fees and reimbursable expenses are included in property operating expenses on the consolidated statements of operations and comprehensive loss. As of December 31, 2019, unpaid construction management fees of $6 are included in liabilities associated with investment properties held for sale on the consolidated balance sheet. The remaining unpaid amounts are included in due to related parties on the consolidated balance sheet.
[4]	The Company pays the Business Manager an annual business management fee equal to 0.65% of its “average invested assets”. The fee is payable quarterly in an amount equal to 0.1625% of its average invested assets as of the last day of the immediately preceding quarter. “Average invested assets” means, for any period, the average of the aggregate book value of the Company’s assets, including all intangibles and goodwill, invested, directly or indirectly, in equity interests in, and loans secured by, properties, as well as amounts invested in securities and consolidated and unconsolidated joint ventures or other partnerships, before reserves for amortization and depreciation or bad debts, impairments or other similar non-cash reserves, computed by taking the average of these values at the end of each month during the relevant calendar quarter. Unpaid amounts are included in due to related parties on the consolidated balance sheets.
