Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization On October 4, 2004, InvenTrust Properties Corp. (the "Company") was incorporated as Inland American Real Estate Trust, Inc. as a Maryland corporation and has elected to be taxed, and currently qualifies, as a real estate investment trust ("REIT") for federal tax purposes. The Company changed its name to InvenTrust Properties Corp. in April of 2015 and is focused on owning, leasing, redeveloping, acquiring and managing a multi-tenant retail platform. The Company is taxed and operates in a manner that will allow the Company to continue to qualify as a REIT for U.S. federal income tax purposes. So long as it maintains its qualification as a REIT, the Company generally will not be subject to U.S. federal income tax on taxable income that is distributed to stockholders. If the Company fails to continue to qualify as a REIT in any taxable year, without the benefit of certain relief provisions, the Company will be subject to U.S. federal and state income tax on its taxable income at regular corporate tax rates and will not be able to re-elect REIT status during the four years following the year of the failure. The accompanying condensed consolidated financial statements include the accounts of the Company, as well as all wholly-owned subsidiaries. Subsidiaries generally consist of limited liability companies ("LLCs") and limited partnerships ("LPs"). All significant intercompany balances and transactions have been eliminated. Each retail property is owned by a separate legal entity that maintains its own books and financial records. Each separate legal entity's assets are not available to satisfy the liabilities of other affiliated entities, except as otherwise disclosed in "Note 6. Investment in Unconsolidated Entities" . As of September 30, 2021 and 2020, the Company had an investment in one unconsolidated real estate joint venture, as disclosed in "Note 6. Investment in Unconsolidated Entities" . The Company determined it has a single reportable segment, multi-tenant retail, for disclosure purposes in accordance with GAAP. The following table summarizes the Company's retail portfolio as of September 30, 2021 and 2020: Wholly-Owned Unconsolidated 2021 2020 2021 2020 No. of properties 55 55 8 10 Gross Leasable Area (square feet) 8,561 8,329 1,994 2,470 New York Stock Exchange Listing On October 12, 2021, the Company’s common stock began trading on the New York Stock Exchange ("NYSE") under the ticker symbol "IVT". Subsequent to September 30, 2021, the Company incurred approximately $16.6 million of advisory fees for legal, banking, and other advisory services, related to the direct listing. These costs were contingent upon a successful direct listing on the NYSE and will be expensed in fourth quarter 2021. "Dutch Auction" Tender Offer On October 12, 2021, in conjunction with the NYSE listing, and in order to provide liquidity to the stockholders of the Company and help stabilize the share price of the Company's common stock, the Company commenced a modified "Dutch Auction" tender offer (the "Tender Offer") to purchase for cash up to $100.0 million of its shares of the Company's common stock at a price not greater than $28.00 nor less than $25.00 per share, net to the seller in cash, less any applicable withholding of taxes and without interest. The Tender Offer expires at 12:00 midnight, New York City time, at the end of the day on November 8, 2021. Reverse Stock Split On August 5, 2021, the Company effected a 1-for-10 reverse stock split of its common stock. As a result of the reverse stock split, every ten shares of issued and outstanding common stock were changed into one share of common stock, with any fractional shares being rounded up to the next higher whole share. Immediately after effecting the reverse stock split, the Company decreased the par value of each issued and outstanding share of common stock from $0.01 par value per share to $0.001 par value per share. In addition, equitable adjustments were made to the maximum number of shares of common stock that may be issued pursuant to the InvenTrust Properties Corp. 2015 Incentive Award Plan (as amended, the "Incentive Award Plan") and the maximum number of shares of common stock that may be issued upon exercise of incentive stock options under the Incentive Award Plan, in each case, to reflect the 1-for-10 reverse stock split. The number of shares of common stock subject to outstanding awards under the Incentive Award Plan, and certain performance goals applicable to such awards, have also been equitably adjusted to reflect the 1-for-10 reverse stock split. Unless otherwise noted, the share information and the Net Asset Value ("NAV") per share of the Company's common stock in this report and accompanying condensed consolidated financial statements have been retroactively adjusted to give effect to the 1-for-10 reverse stock split for all periods presented. Impact of the COVID-19 Pandemic on the Company's Financial Statements The impact of the coronavirus disease 2019 ("COVID-19") pandemic has not materially changed from the information included in the Company's Annual Report or other current reports on file with the Securities and Exchange Commission. The primary impact of the pandemic was and continues to be related to the Company's tenants' ability to make their future rental payments in a timely fashion or at all. During the nine months ended September 30, 2021, deferred rental payments of $4,331 became due and the Company has collected $4,234 of such deferred rental payments as of September 30, 2021. As of September 30, 2021, the Company has granted approximately $5,346 on a cumulative basis of rental payment deferrals, with contractual payment terms through the year ending December 31, 2023.

Basis of Presentation and Recently Issued Accounting Pronouncements	Basis of Presentation and Recently Issued Accounting Pronouncements The accompanying condensed consolidated financial statements have been prepared in accordance with GAAP, which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates, judgments and assumptions are required in a number of areas, including, but not limited to, evaluating the impairment of long-lived assets, allocating the purchase price of acquired retail properties, determining the fair value of debt and evaluating the collectibility of accounts receivable. The Company bases these estimates, judgments and assumptions on historical experience and various other factors that the Company believes to be reasonable under the circumstances. Actual results may differ from these estimates. Reclassifications Restricted cash of $1,160 as of December 31, 2020 has been reclassified to cash, cash equivalents and restricted cash on the condensed consolidated balance sheets. Recently Issued Accounting Pronouncements Adopted Standard Description Date of adoption Effect on the financial statements or other significant matters ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope ASU 2021-01 is intended to clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. Topic 848 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. Application of these expedients, which may be elected over time as reference rate reform activities occur, preserves the presentation of derivatives consistent with past presentation. January 2021 The Company's adoption of ASU No. 2021-01 did not result in any incremental elections under Topic 848 regarding cash flow hedges. The Company continues to evaluate the guidance of Topic 848. The Company expects that application of Topic 848 will not change its presentation of derivatives as cash flow hedges. Other recently issued accounting standards or pronouncements not disclosed in the foregoing table have been excluded because they are either not relevant to the Company, or are not expected to have, or did not have, a material effect on the condensed consolidated financial statements of the Company.

Investment in Unconsolidated Entities	Investment in Unconsolidated Entities Joint Venture Interests IAGM Retail Fund I, LLC As of September 30, 2021 and December 31, 2020, the Company owned a 55% interest in one unconsolidated entity, IAGM Retail Fund I, LLC ("IAGM"), a retail joint venture partnership between the Company and PGGM Private Real Estate Fund ("PGGM"). As of September 30, 2021 and December 31, 2020, the carrying value of the Company's investment in IAGM was $104,963 and $109,051, respectively. During the nine months ended September 30, 2021, the Company purchased Prestonwood Town Center from IAGM for $52,800, a purchase price determined by a third party real estate valuation specialist, which resulted in IAGM recognizing a gain on sale of $12,428. The Company deferred its share of IAGM's gain on sale of $6,835, which is being amortized over 30 years as an increase to equity in earnings of unconsolidated entities. During the nine months ended September 30, 2021, IAGM disposed of Westover Marketplace, a 243 thousand square foot retail property, for a gross disposal price of $28,775 and recognized a gain on sale of $399. The Company's share of IAGM's gain on sale was $219. During the nine months ended September 30, 2020, the Company purchased Antoine Town Center from IAGM for $22,254, a purchase price determined by a third party real estate valuation specialist, which resulted in IAGM recognizing a gain on sale of $1,741. The Company deferred its share of IAGM's gain on sale of $958 which is being amortized over 30 years as an increase to equity in earnings of unconsolidated entities. Subsequent to purchasing Antoine Town Center, the Company completed a sale of an outparcel at this retail property to an unrelated third party which resulted in recognizing $54 of previously deferred gain. During the nine months ended September 30, 2021 and 2020, IAGM prepaid mortgages payable of $23,150 and $14,872, respectively, with cash on hand. IAGM used cash on hand and proceeds from the sale of Prestonwood Town Center to pay down $54,103 of its mortgage debt during the nine months ended September 30, 2021. During the nine months ended September 30, 2020, IAGM entered into two interest rate swap agreements to achieve fixed interest rates on its senior secured term loan facility previously subject to variability in the London Inter-bank Offered Rate ("LIBOR"). Each of the interest rate swaps have an effective date of April 1, 2020 and a termination date of November 2, 2023. One interest rate swap has a notional amount of $45,000 and achieves a fixed interest rate of 1.979%. The other interest rate swap has a notional amount of $30,000 and achieves a fixed interest rate of 1.956%. The Company recognizes its share of gains or losses resulting from IAGM's interest rate swaps as an adjustment to the Company's investment in IAGM and an increase or decrease in comprehensive income. As of September 30, 2021, the interest rate swaps were recorded as a liability with a fair value of $97 on IAGM's condensed consolidated balance sheet, of which the Company's share was $53.

(c) As of September 30, 2021 and December 31, 2020, the Company determined that the credit valuation adjustments associated with nonperformance risk are not significant to the overall valuation of its derivatives. As a result, the Company's derivative valuations in their entirety are classified as Level 2 of the fair value hierarchy. Nonrecurring Measurements Investment Properties During the three and nine months ended September 30, 2021 , the Company had no Level 3 nonrecurring fair value measurements. During the nine months ended September 30, 2020, the Company identified one retail property that had a reduction in its expected holding period and recorded a provision for asset impairment of $9,002 on the condensed consolidated statement of operations and comprehensive income (loss) as a result of the fair value being lower than the property's carrying value. The Company's fair value was based on an executed sales contract. This property was disposed of on May 1, 2020. During the three months ended September 30, 2020, the Company had no Level 3 recurring fair value measurements. Financial Instruments Not Measured at Fair Value The table below summarizes the estimated fair value of financial instruments presented at carrying values in the Company's condensed consolidated financial statements as of September 30, 2021 and December 31, 2020: September 30, 2021 December 31, 2020 Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value Mortgages payable $ 106,288 $ 105,217 $ 107,261 $ 106,494 Term loans $ 400,000 $ 400,038 $ 400,000 $ 400,055 Revolving line of credit $ — $ — $ 50,000 $ 50,032 The Company estimated the fair value of its mortgages payable using a weighted-average effective market interest rate of 4.43% and 4.25% as of September 30, 2021 and December 31, 2020, respectively. The Company estimated the fair value of its term loans and revolving line of credit using a weighted-average interest rate of 2.16% and 1.36% as of September 30, 2021 and December 31, 2020, respectively. The Company has determined that its debt instrument valuations are classified in Level 2 of the fair value hierarchy. The fair value estimates of the term loans and line of credit approximate the carrying values. The assumptions reflect the terms currently available on similar borrowings by borrowers with credit profiles similar to the Company's.

Earnings Per Share [Abstract]
Earnings Per Share and Equity Transactions	Earnings Per Share and Equity Transactions Basic earnings per share ("EPS") is computed using the two-class method by dividing net income or loss by the weighted average number of common shares outstanding for the period (the "common shares") and participating securities. The time-based restricted share awards issued pursuant to the Incentive Award Plan are deemed to be participating securities. Diluted EPS is generally computed using the treasury-stock method by dividing net income or loss by the common shares plus potential common shares resulting from time-based restricted share awards. The following table reconciles the amounts used in calculating basic and diluted earnings per share: Three months ended September 30, Nine months ended September 30, 2021 2020 2021 2020 Numerator: Net income (loss) attributed to common shareholders $ 3,992 $ 1,677 $ 5,391 $ (11,420) Denominator: Weighted average common shares outstanding - basic 71,261,403 71,945,847 71,731,832 72,072,252 Dilutive effect of unvested restricted shares (a) 134,222 63,362 70,250 — Weighted average common shares outstanding - diluted 71,395,625 72,009,209 71,802,082 72,072,252 Basic and diluted earnings per common share: Net income (loss) per common share, basic and diluted $ 0.06 $ 0.02 $ 0.08 $ (0.16) (a) For the nine months ended September 30, 2020, unvested restricted shares were anti-dilutive. On August 5, 2021, the Company effected a 1-for-10 reverse stock split of its common stock, reducing the number of shares of common stock outstanding from 712,090,283 to 71,261,403 shares on that date. Fractional shares resulted in the issuance of an additional 52,375 shares, which have been included in the total issued and outstanding shares for all periods presented. See "Note 1. Organization" for more information concerning the reverse stock split. On April 6, 2021, the Company adopted the Third Amended and Restated Share Repurchase Program, (as amended, the "SRP"). On April 12, 2021, the Company announced the reinstatement of the SRP, effective May 14, 2021, for qualifying shareholders. The repurchase price per share of $21.70 for eligible stockholders is equal to a 25% discount to the most recent estimated NAV per share of the Company's common stock established by the Company's board of directors (the "Board"), which was $28.90 per share as of December 1, 2020. During the nine months ended September 30, 2021, 755,643 shares were repurchased in connection with the SRP. On August 5, 2021, the Board suspended the SRP effective September 5, 2021.

Topic 848 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. Application of these expedients, which may be elected over time as reference rate reform activities occur, preserves the presentation of derivatives consistent with past presentation. January 2021 The Company's adoption of ASU No. 2021-01 did not result in any incremental elections under Topic 848 regarding cash flow hedges. The Company continues to evaluate the guidance of Topic 848. The Company expects that application of Topic 848 will not change its presentation of derivatives as cash flow hedges. Other recently issued accounting standards or pronouncements not disclosed in the foregoing table have been excluded because they are either not relevant to the Company, or are not expected to have, or did not have, a material effect on the condensed consolidated financial statements of the Company.
