Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization The Company was incorporated as Inland American Real Estate Trust, Inc. in October 2004, 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 2015. The Company was formed to own, manage, acquire and develop a diversified portfolio of commercial real estate located throughout the United States and to own properties in development and partially own properties through joint ventures, as well as investments in marketable securities and other assets. The Company no longer owns a diversified portfolio and is now focused on being a multi-tenant retail platform. As used in these Notes and throughout this Quarterly Report on Form 10-Q, the terms "Company," "InvenTrust," "we," "us," or "our" mean InvenTrust Properties Corp. and its wholly owned and unconsolidated joint venture investments. Unless otherwise noted, all dollar amounts are stated in thousands, except share, per share, square foot and per square foot amounts. Segment Reporting Following the Highlands REIT, Inc. ("Highlands") spin-off and sale of the student housing platform, University House Communities Group, Inc. ("University House"), in 2016, as disclosed in the Company's Annual Report, the Company no longer has a non-core or student housing segment, respectively, as previously reported. Highlands and the Company operate independently as two separate companies, each having their own management team and board of directors. In addition, the Company disposed of its remaining non-core asset, Worldgate Plaza, on August 30, 2017, which represented the conclusion of the Company's strategic shift away from assets not classified as multi-tenant retail. These previously reported segments were classified as discontinued operations as they represented a strategic shift that had a major effect on the Company's operations and financial results. The assets and liabilities related to discontinued operations were separately classified on the consolidated balance sheet as of December 31, 2015, and the operations were classified as net income from discontinued operations on the consolidated statements of operations and comprehensive income for the three and nine months ended September 30, 2016. With the completion of the University House sale and Highlands spin-off in 2016 as well as the disposal of Worldgate Plaza in 2017, the Company is now fully focused on investing in a multi-tenant retail platform as described above. In addition, the Company's assets now have similar characteristics, such as tenant type and economic performance, are all multi-tenant retail assets, and the Company does not distinguish its principal business or group its operations on a geographical basis for measuring performance. Accordingly, the Company believes it has a single reportable segment for disclosure purposes in accordance with GAAP as of September 30, 2017 . The accompanying 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 multi-tenant retail asset is owned by a separate legal entity which maintains its own books and financial records, and each separate legal entity's assets are not available to satisfy the liabilities of other affiliated entities, except as otherwise disclosed in "Note 7. Debt". As of September 30, 2017 , the Company's multi-tenant retail portfolio included 70 wholly owned multi-tenant retail assets with 12,253,822 square feet, of which approximately 94.4% was occupied, two consolidated multi-tenant retail assets considered Parked Assets as legal title was held by a wholly owned subsidiary of an Exchange Accommodation Titleholder (the "EAT") pending completion of a reverse like-kind exchange under Section 1031 of the Internal Revenue Code of 1986 (the "Code") ("Reverse 1031 Exchange") (see "Note 5. Investment in Consolidated and Unconsolidated Entities"), with 501,276 square feet, of which approximately 98% was occupied. In addition, the Company held a significant investment in two operating real estate joint ventures, one of which the Company owns an interest in as well as manages 15 multi-tenant retail assets with 2,977,303 square feet within the joint venture. As of December 31, 2016, the Company had 72 wholly owned assets, which included 71 multi-tenant retail assets and one non-core office asset. As of September 30, 2016 , the Company owned a combined total of 74 assets, which included multi-tenant retail assets and a non-core office asset. As of December 31, 2016 and September 30, 2016 , the Company also managed 15 multi-tenant retail assets owned by an unconsolidated joint venture.

Accounting Policies [Abstract]
Basis of Presentation and Recently Issued Accounting Pronouncements	Basis of Presentation and Recently Issued Accounting Pronouncements The accompanying consolidated financial statements reflect the consolidated financial position of the Company as of September 30, 2017 and December 31, 2016, the consolidated results of its operations for the three and nine months ended September 30, 2017 and 2016, and the consolidated statement of its cash flows for the nine months ended September 30, 2017 and 2016. These 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 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. 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 assets, determining the fair value of debt and evaluating the collectability 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 Certain reclassifications have been made to the consolidated statements of operations and comprehensive income for the three and nine months ended September 30, 2016 to conform to the 2017 presentation. These are as follows: • the reclassification of fees earned from providing property management, asset management, leasing commissions and other services to our unconsolidated joint venture partnerships from other income to other fee income for the three and nine months ended September 30, 2016 of $1,106 and $3,187 , respectively; and • the reclassification of depreciation and amortization incurred on corporate level assets from general and administrative expenses to depreciation and amortization of $304 and $778 for the three and nine months ended September 30, 2016 , respectively, of which $60 was included as part of net income from discontinued operations for the nine months ended September 30, 2016 . In addition, certain reclassifications have been made to the consolidated balance sheet as of December 31, 2016 and the consolidated statements of operations and comprehensive income for the nine months ended September 30, 2017 to reflect the results of Worldgate Plaza (sold on August 30, 2017), and for the three and nine months ended September 30, 2016 to reflect the results of Highlands (spun off on April 28, 2016), University House (sold on June 21, 2016) and Worldgate Plaza as discontinued operations. Recently Issued Accounting Pronouncements Adopted In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-01, Clarifying the Definition of a Business , with the objective of providing guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The revised guidance will result in most of the Company's real estate transactions being classified as asset acquisitions and asset disposals. The guidance is effective beginning January 1, 2018. Early adoption is permitted. The Company early adopted ASU No. 2017-01 as of October 1, 2016. In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation, which outlines improvements to employee share-based payment accounting. The new standard impacts certain aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statements of cash flows. The Company has concluded that its adoption of ASU No. 2016-09, as issued, did not have a significant impact on the consolidated financial statements. The Company adopted ASU No. 2016-08 as of January 1, 2017. Recently Issued Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those promised goods or services. The ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective, although it will not affect the accounting for revenue deemed to be related to lease components of contracts. In April 2015, the FASB approved an amendment to the ASU, deferring the effective date one year to annual reporting periods beginning after December 15, 2017 for public entities. The standard permits the use of either the retrospective or cumulative effect transition method. Early adoption is prohibited. Most significantly for the real estate industry, revenue deemed to be related to non-lease components of contracts is within the scope of the new standard. A majority of the Company’s tenant-related revenue is related to lease components, and will be governed by the recently issued leasing guidance discussed below. As a result, while the total revenue recognized over time would not differ under the new guidance, the recognition pattern and presentation of revenue related to non-lease components would be different. The Company anticipates expanded quantitative and qualitative disclosures regarding revenue recognition will be required for contracts with customers that are subject to this guidance. However, the Company may elect certain practical expedients of the recently issued leasing guidance. As a result, the Company may generally not need to revisit historical accounting for leases executed prior to the leasing guidance effective date, which will be effective for annual reporting periods beginning after December 15, 2018. The Company intends to implement the standard retrospectively with the cumulative effect (if any) recognized in retained earnings at the date of initial application. The Company will utilize the single practical expedient available and apply the guidance to new and existing contracts entered into subsequent to the date of initial application. The Company has completed a preliminary review of this standard to identify and document specific areas that will be affected by its adoption. In addition to revenue deemed to be related to non-lease components, the recognition of other fee income on the consolidated statements of operations and comprehensive income will be governed primarily by the new standard. The Company is continuing to evaluate this guidance and it does not expect its adoption will have a significant impact on the consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities , which (a) requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (b) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (c) eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities; (d) eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; (e) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (f) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; and (g) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. ASU No. 2016-01 will be effective for annual reporting periods, including interim periods within those annual periods, beginning after December 15, 2017. Entities may early adopt the provisions related to the recognition of changes in fair value of financial liabilities. Entities must apply the standard using a cumulative effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The Company’s investments in marketable securities on the consolidated balance sheets are currently classified as available-for-sale and measured at fair value each reporting period. Changes in fair value are currently recorded through comprehensive income. As of the date of adoption, all unrealized gains or losses on available-for-sale equity securities will be reclassified to beginning retained earnings in the year of adoption. All subsequent changes in the fair value of the Company’s investments that have readily determinable fair values will be recognized through net income. The Company will continue to evaluate the impact of this guidance until adoption. In February 2016, the FASB issued ASU No. 2016-02, Leases , amending the existing guidance for lease accounting for both parties to a lease contract (i.e. lessees and lessors). For lessees, the new standard requires application of a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset ("ROU") and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. For lessors, the new standard requires accounting for leases using a method that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASU No. 2016-02 will be effective for annual reporting periods beginning after December 15, 2018, and early adoption is permitted as of the standard's issuance date. The new standard requires a modified retrospective transition method for all leases existing at the date of initial application, with an option to use certain practical expedients available. On June 21, 2017 the FASB met to discuss an implementation question related to the adoption of ASU No. 2014-09 and ASU No. 2016-02. The FASB clarified that companies will not need to revisit the allocation of contract consideration to lease and non-lease components within the scope of ASU No. 2016-02 when an entity adopts ASU No. 2014-09. This clarification is limited to situations where companies decide not to early adopt ASU No. 2016-02 coincident with ASU No. 2014-09. Based on this clarification, if the Company elects the package of practical expedients, it will not need to revisit historical accounting for leases. Therefore, ASU No. 2016-02 would only apply to new leases executed after the effective date of January 1, 2019. As a lessee, the Company believes the most significant change relates to the recognition of a new ROU asset and lease liability on the consolidated balance sheets for its corporate office leases, as well as a ground lease agreement where the Company is the lessee (see Note 12). Currently, the Company accounts for both the office and the ground lease arrangement as operating leases and they are not material to the Company’s consolidated financial statements. As a lessor, the Company believes substantially all of the Company's leases will continue to be classified as operating leases under the new standard. Common area maintenance ("CAM"), utility recovery services, and non-routine major maintenance provided for in tenant lease contracts will be accounted for as non-lease components within the scope of the new revenue standard. As a result, we will be required to recognize revenues associated with tenant leases separately from revenues associated with CAM, utility recovery services, or non-routine major maintenance. The Company also has certain lease arrangements with its tenants for space at its retail assets in which the contractual amounts due under the lease from the lessee are not allocated between the rental and expense reimbursement components ("Gross Leases"). Presently, the aggregate revenue earned under Gross Leases is classified as rental income in the consolidated statements of operations. Under the new standard, the Company anticipates it will be required to allocate the embedded revenue associated with these reimbursements under its Gross Leases, which represent an immaterial portion of the Company’s lease portfolio, and separately present such amounts in its consolidated statements of operations. Lastly, due to the new standard’s narrowed definition of initial direct costs, the Company expects to expense as incurred certain lease origination costs currently capitalized and amortized to expense over the lease term. However, the Company does not believe this change will have a material impact on its consolidated financial statements. The Company will continue to evaluate the impact of this guidance until adoption on January 1, 2019. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows . This guidance is intended to reduce the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The core principle of the ASU requires the classification of eight specific issues identified under Accounting Standards Codification ("ASC") ASC 230, Statement of Cash Flows, to be presented as either financing, investing or operating, or some combination thereof, depending upon the nature of the cash flows. ASU No. 2016-15 will be effective for annual reporting periods, including interim periods within those annual periods, beginning after December 15, 2017, and early adoption is permitted. Entities are required to use a retrospective transition method for each period presented. Of the eight specific issues identified, the following clarifications are most pertinent to the Company: (a) cash payments for debt prepayment and extinguishment costs are presented as cash outflows from financing activities; (b) cash proceeds from the settlement of insurance claims are presented based on the nature of the loss; (c) distributions from equity method investments must be classified as investing or operating, or some combination thereof, based on an accounting policy election. The Company’s current presentation of cash payments for debt prepayment and extinguishment costs and cash proceeds from the settlement of insurance claims is in accordance with the standard. The Company currently utilizes the nature of the distribution approach regarding distributions from equity method investments, which will be formalized as an accounting policy in accordance with the standard. Under this approach, each distribution is evaluated on the basis of the source of the payment and classified as either operating cash inflows or investing cash inflows. The Company anticipates the adoption of this standard on January 1, 2018, and does not expect its adoption will have a significant impact on the consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows. The guidance is intended to reduce the existing diversity in practice of how certain transfers between cash and restricted cash are classified as operating, investing, or financing activities within the statement of cash flows. ASU No. 2016-18 will be effective for annual reporting periods beginning after December 31, 2017, and interim periods within those fiscal years. Early adoption is permitted. This guidance requires a retrospective transition method of adoption for each period presented. Under the standard, entities are required to explain the changes in the combined total of restricted and unrestricted cash in the statement of cash flows. As a result, a transfer between restricted and unrestricted cash accounts will not be reported as a cash flow. All cash receipts/payments with third parties directly to/from restricted cash accounts will be reported as operating, investing, or financing cash flows, as appropriate. In February 2017, the FASB issued ASU No. 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets. The new guidance is required to be adopted concurrently with the amendments in ASU 2014-09, Revenue from Contracts with Customers . The standard, which adds guidance for partial sales of nonfinancial assets and clarifies the scope of Subtopic 610-20, Gains and Losses from the Derecognition of Nonfinancial Assets , applies to the derecognition of all nonfinancial assets (including real estate) for which the counterparty is not a customer. Public entities should apply the amendments in this standard to annual periods beginning after December 15, 2017, including interim periods within those periods. The Company anticipates the adoption of this standard on January 1, 2018, and does not expect its adoption will have a significant impact on the consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities . This guidance is intended to better align financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides the option of early adopting the new standard using a modified retrospective transition method in any interim period, or alternatively requires adoption for fiscal years beginning after December 15, 2018. This adoption method will require the Company to recognize the cumulative effect of initially applying the ASU as an adjustment to accumulated comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that it adopts the update. The Company is continuing to evaluate this guidance and does not expect its adoption will have a significant impact on the consolidated financial statements.

Investment in Partially Owned Entities [Abstract]
Investment in Partially Owned Entities	Investment in Consolidated and Unconsolidated Entities Consolidated Entities During the third quarter of 2017, the Company entered into purchase agreements structured as Reverse 1031 Exchanges in order to acquire River Oaks and Kyle Marketplace. For a Reverse 1031 Exchange in which the Company purchases a new asset that is similar in nature, character, or class prior to selling the asset to be matched in the like-kind exchange (the Company refers to a new asset being acquired in the Reverse 1031 Exchange prior to the sale of the related asset as a "Parked Asset"), legal title to the Parked Asset is held by a wholly owned subsidiary of the EAT engaged to execute the Reverse 1031 Exchange until the sale transaction and the Reverse 1031 Exchange is completed. The Company, through a subsidiary, enters into a master lease agreement with the wholly owned subsidiary of the EAT whereby the EAT leases the Parked Asset and all other rights in connection with the acquisition to the Company. The master lease terminates on the earlier of (i) the date that the Parked Asset is transferred to the Company, or an affiliate, (ii) EAT transfers its ownership in the Parked Asset to the Company, or an affiliate thereof, or (iii) 180 days from the date that the asset was acquired in which title transfers to the Company. The EAT is classified as a variable interest entity ("VIE"), as defined in FASB ASC 810, Consolidation, as it does not have sufficient equity investment at risk to finance its activities without additional subordinated financial support. River Oaks and Kyle Marketplace were deemed to be VIEs, for which the Company was deemed to be the primary beneficiary as it has the ability to direct the activities of the entities that most significantly impact economic performance and has all of the risks and rewards of ownership. Accordingly, the Company has consolidated River Oaks and Kyle Marketplace. The following were the assets and liabilities of the consolidated VIEs. The liabilities of the VIEs are not recourse to the Company, and the assets must be used first to settle obligations of the VIEs. As of September 30, 2017, River Oaks and Kyle Marketplace were the Company's only active Reverse 1031 Exchanges. September 30, 2017 December 31, 2016 Net investment properties $ 167,017 $ — Other assets 17,024 — Total assets 184,041 — Other liabilities 10,649 — Total liabilities 10,649 — Net assets $ 173,392 $ — During the third quarter of 2017, the Company acquired The Plaza Midtown (see "Note 3. Acquired Assets"), consisting of wholly owned multi-tenant retail space, and an undivided interest in certain common elements as tenants-in-common. An undivided interest is an ownership arrangement in which two or more parties jointly own property, and title is held individually to the extent of each party’s interest. The common elements primarily consist of a parking garage adjacent to the wholly owned multi-tenant retail space. The ownership of The Plaza Midtown was deemed to not be subject to joint control, as the other tenant-in-common lacked the ability to effectively participate in the decisions that most significantly impact economic performance of The Plaza Midtown. Accordingly, the Company has applied proportionate consolidation of the common elements. The parking garage had an estimated proportionate fair value of $10,790 at the acquisition date, which has been included in land and building and other improvements of $1,963 and $8,827 , respectively, on the consolidated balance sheet as of September 30, 2017 . Unconsolidated Entities The entities listed below are owned by the Company and other unaffiliated parties in joint ventures. Net income, distributions and capital transactions for these entities are allocated to the Company and its joint venture partners in accordance with the respective partnership agreements. The Company analyzed the joint venture agreements and determined that the joint ventures were not VIEs. The Company also considered the joint venture partners' participating rights under the joint venture agreements and determined that the joint venture partners have the ability to participate in major decisions, which equates to shared decision making. Accordingly, the Company has significant influence but does not control the joint ventures. Therefore, these joint ventures are not consolidated by the Company and the equity method of accounting is used to account for these investments. Under the equity method of accounting, the net equity investment of the Company and the Company's share of net income or loss from the unconsolidated entity are reflected in the consolidated balance sheets and the consolidated statements of operations and comprehensive income . Carrying Value of Investment as of Entity Description Ownership % September 30, 2017 December 31, 2016 IAGM Retail Fund I, LLC Multi-tenant retail shopping centers 55% $ 128,778 $ 126,090 Downtown Railyard Venture, LLC Land development 90% 56,429 52,365 Other unconsolidated entities Various real estate investments Various (111 ) 273 $ 185,096 $ 178,728 During the three and nine months ended September 30, 2017, the Company received a final distribution from one unconsolidated entity of $366 , which reduced the Company's investment in the unconsolidated entity to zero as of September 30, 2017. No gain or loss was recognized as part of the transaction. A gain on the sale of a joint venture for the development of a student housing community of $1,434 was recorded for the nine months ended September 30, 2016 and is included as part of net income from discontinued operations on the consolidated statements of operations and comprehensive income .

It is anticipated that the joint ventures will be able to repay or refinance all of their debt on a timely basis.

Investments, All Other Investments [Abstract]
Investment in Marketable Securities	Investment in Marketable Securities Investment in marketable securities of $35,547 and $183,883 at September 30, 2017 and December 31, 2016 , respectively, consists primarily of preferred and common stock investments in other REITs and certain real estate related bonds which are classified as available-for-sale securities and recorded at fair value. The cost basis net of impairments of available-for-sale securities was $21,322 and $125,311 as of September 30, 2017 and December 31, 2016 , respectively. The Company recognized net proceeds from sales of marketable securities of $140,171 during the nine months ended September 30, 2017. Unrealized holding gains and losses on available-for-sale securities are excluded from earnings and reported as a separate component of comprehensive income until realized. The Company has net accumulated comprehensive income related to its marketable securities portfolio of $14,225 and $58,572 , which includes gross unrealized losses of $36 and $598 related to its marketable securities as of September 30, 2017 and December 31, 2016 , respectively. Securities with gross unrealized losses have a related fair value of $0 and $1,204 as of September 30, 2017 and December 31, 2016 , respectively. The Company’s policy for assessing recoverability of its available-for-sale securities is to record a charge against net earnings when the Company determines that a decline in the fair value of a security drops below the cost basis and believes that decline to be other-than-temporary. Factors in the assessment of other-than-temporary impairment include determining whether (1) the Company expects the value of the security to recover, (2) the Company has the ability and intent to hold the security until it recovers, and (3) the length of time and degree to which the security’s price has declined. The Company recorded no impairment on available-for-sale securities for the three and nine months ended September 30, 2017 . Other-than-temporary impairment to available-for-sale securities of $1,327 was recorded for the three and nine months ended September 30, 2016 as part of continuing operations in interest and dividend income on the consolidated statements of operations and comprehensive income . Dividend income is recognized when earned. During the three and nine months ended September 30, 2017 , dividend income of $350 and $2,582 , respectively, was recognized and is included as part of continuing operations in interest and dividend income on the consolidated statements of operations and comprehensive income . During the three and nine months ended September 30, 2016 , $2,650 and $7,950 , respectively, was recognized and is included as part of continuing operations in interest and dividend income on the consolidated statements of operations and comprehensive income .

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements In accordance with ASC 820, Fair Value Measurement and Disclosures , the Company defines fair value based on the price that 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 uses 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. 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. Recurring Measurements For assets and liabilities measured at fair value on a recurring basis, quantitative disclosure of the fair value for each major category of assets and liabilities is presented below: Fair Value Measurements at September 30, 2017 Assets Level 1 Level 2 Level 3 Available-for-sale marketable securities $ 35,224 $ — $ — Real estate related bonds — 323 — Derivative interest rate swaps — 913 — Total assets $ 35,224 $ 1,236 $ — Fair Value Measurements at December 31, 2016 Assets Level 1 Level 2 Level 3 Available-for-sale marketable securities $ 182,569 $ — $ — Real estate related bonds — 1,314 — Derivative interest rate swaps — 487 — Total assets $ 182,569 $ 1,801 $ — Level 1 At September 30, 2017 and December 31, 2016 , the fair value of the available-for-sale marketable equity securities have been estimated based upon quoted market prices. Unrealized gains or losses on investment are reflected in unrealized gain (loss) on investment securities in comprehensive income on the consolidated statements of operations and comprehensive income . Level 2 To calculate the fair value of the real estate related bonds and the derivative interest rate instruments, the Company primarily uses quoted prices for similar securities and contracts. For the real estate related bonds, the Company reviews price histories for similar market transactions. For the derivative interest rate instruments, the Company uses inputs based on data that is observed in the forward yield curve which is widely observable in the marketplace. The Company also incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements which utilizes Level 3 inputs, such as estimates of current credit spreads. However, as of September 30, 2017 and December 31, 2016 , the Company determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. As of September 30, 2017 and December 31, 2016 , the Company had outstanding interest rate swap agreements with an aggregate notional value of $150,000 . Level 3 At September 30, 2017 and December 31, 2016 , the Company had no Level 3 recurring fair value measurements. Nonrecurring Measurements The following table summarizes activity for the Company’s assets measured at fair value on a nonrecurring basis. The Company recognized certain impairment charges to reflect the investments at their fair values for the three and nine months ended September 30, 2017 and 2016 . The asset groups that were reflected at fair value through this evaluation are: For the three months ended September 30, 2017 2016 Level 3 Impairment Losses Level 3 Impairment Losses Investment properties, continuing operations $ — $ — $ 27,173 $ 2,818 Investment properties, discontinued operations — — — — Total $ — $ 2,818 For the nine months ended September 30, 2017 2016 Level 3 Impairment Losses Level 3 Impairment Losses Investment properties, continuing operations $ 36,676 $ 16,440 $ 66,323 $ 11,208 Investment properties, discontinued operations — — 584,358 106,514 Total $ 16,440 $ 117,722 Investment properties, continuing operations During the three and nine months ended September 30, 2017 , the Company identified certain assets which may have a reduction in the expected holding period and reviewed the probability of these assets' disposition. The Company's estimated fair value relating to the investment assets' impairment analyses was based on broker opinions of value and letters of intent and 10 -year discounted cash flow models, which include estimated inflows and outflows over a specific holding period and estimated net disposition proceeds at the end of the 10 -year period. The cash flows consist of observable inputs such as contractual revenues and unobservable inputs such as forecasted revenues and expenses and estimated net disposition proceeds at the end of the 10 -year period. These unobservable inputs are based on market conditions and the Company’s expected growth rates. As a result, during the nine months ended September 30, 2017 , the Company recorded a provision for asset impairment of $16,440 in continuing operations on three multi-tenant retail assets based on broker opinions of value and letters of intent. There was no provision for asset impairment recorded for the three months ended September 30, 2017 . During the three and nine months ended September 30, 2016 , the Company identified certain assets which may have a reduction in the expected holding period and reviewed the probability of these assets' disposition. The Company's estimated fair value relating to the investment assets' impairment analyses was based on purchase contracts. As a result, during the three and nine months ended September 30, 2016 , the Company recorded a provision for asset impairment of $2,818 and $11,208 , respectively, in continuing operations on three multi-tenant retail assets. Investment properties, discontinued operations In connection with the Highlands spin-off during the nine months ended September 30, 2016 , as disclosed in the Company's Annual Report, the Company evaluated Highlands as a disposal group for impairment. The Company's estimated fair value relating to the disposal group's impairment analysis was based on 10 -year discounted cash flow models, which include estimated inflows and outflows over a specific holding period and estimated net disposition proceeds at the end of the 10 -year period. The cash flows consist of observable inputs such as contractual revenues and unobservable inputs such as forecasted revenues and expenses and estimated net disposition proceeds at the end of the 10 -year period. These unobservable inputs are based on market conditions and the Company’s expected growth rates. As of the spin date, capitalization rates ranging from 6.75% to 10.00% and discount rates ranging from 7.75% to 15.25% were utilized in the model and were based upon observable rates that the Company believed to be within a reasonable range of current market rates. As a result of this analysis, the Company recorded a provision for asset impairment related to the Highlands spin-off of $76,583 for the nine months ended September 30, 2016 . During the nine months ended September 30, 2016 , the Company identified one non-core office asset which may have a reduction in the expected holding period and reviewed the probability of this asset's disposition. The Company's estimated fair value relating to this asset's impairment analysis was based on a ten-year undiscounted cash flow model. Capitalization rates ranging from 6.75% to 7.00% and discount rates ranging from 7.00% to 8.00% were utilized in the model and were based upon observable rates that the Company believed to be within a reasonable range of market rates. As a result of this analysis, the Company recorded a provision for asset impairment of $29,931 on this asset, for a total provision for asset impairment of $106,514 in discontinued operations for the nine months ended September 30, 2016 . There was no provision for asset impairment recorded as part of discontinued operations for the three months ended September 30, 2016 . Financial Instruments Not Measured at Fair Value The table below represents the fair value of financial instruments presented at carrying values in the Company's consolidated financial statements as of September 30, 2017 and December 31, 2016 . September 30, 2017 December 31, 2016 Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value Mortgages payable $ 370,029 $ 372,418 $ 434,746 $ 435,513 Line of credit and term loan $ 300,000 $ 299,760 $ 300,000 $ 299,741 The Company estimated the fair value of its mortgages payable using a weighted average effective market interest rate of 4.19% as of September 30, 2017 compared to 5.07% as of December 31, 2016. The fair value estimate of the line of credit and term loan approximates the carrying value due to limited market volatility in pricing. The assumptions reflect the terms currently available on similar borrowing terms to borrowers with credit profiles similar to the Company's. As a result, the Company used a weighted average interest rate of 3.21% as of September 30, 2017 compared to 3.15% as of December 31, 2016 to estimate the fair value of its line of credit and term loan. The Company has determined that its debt instrument valuations are classified in Level 2 of the fair value hierarchy.

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic earnings per share ("EPS") are computed using the two-class method by dividing net income by the weighted average number of common shares outstanding for the period (the "common shares"). Diluted EPS is computed using the treasury method if more dilutive, by dividing net income by the common shares plus potential common shares issuable upon exercising options or other contracts. The following table reconciles the amounts used in calculating basic and diluted income per share.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is subject, from time to time, to various types of third-party legal claims or litigation that arise in the ordinary course of business, including, but not limited to, property loss claims, personal injury or other damages resulting from contact with the Company’s properties. These claims and lawsuits and any resulting damages are generally covered by the Company's insurance policies. The Company accrues for legal costs associated with loss contingencies when these costs are probable and reasonably estimable. While the resolution of these matters cannot be predicted with certainty, management does not expect, based on currently available information, that the final outcome of any pending claims or legal proceedings will have a material adverse effect on the financial condition, results of operations or cash flows of the Company. As previously disclosed in our Quarterly Report for the quarter ended June 30, 2017, on September 6, 2013, a former tenant at the Legacy Corner Apartments property in Midwest City, Oklahoma filed a complaint in the District Court of Oklahoma County against the Company and other named defendants, Case No. CJ-2013-5011, alleging premises liability and negligent maintenance. At December 31, 2016, based on the facts and circumstances of this case, the Company believed it had a viable defense and was prepared to defend the suit vigorously. Due to the pendency of the Company's defenses and insurance policies, together with the inherent difficulty and uncertainty of predicting the outcome of litigation generally, the Company did not believe a risk of loss associated with compensatory damages was probable. Furthermore, the Company did not believe a risk of loss associated with punitive damages, which would be awarded due to gross negligence, was probable based on the information known, nor did the Company know what an estimated range of uninsured punitive damages could be. Therefore, at December 31, 2016, no loss contingency amounts related to this case had been accrued. The jury trial commenced on April 3, 2017. On April 12, 2017, the jury entered a verdict against the Company’s subsidiary and the other named defendants in favor of the plaintiff of $6,000 in compensatory damages and $6,000 in punitive damages. The compensatory portion of the verdict is fully insured by the Company’s insurance policies. However, the Company's insurance carrier served the Company with a reservation of rights letter stating that insurance coverage may not be provided for punitive damages awarded in this case. As a result, the Company’s potential loss contingency exposure was $6,000 . During the quarter ended June 30, 2017, one of the Company's insurance carriers provided a $1,000 payment to the plaintiff. On July 27, 2017, the plaintiff asserted a demand against the Company’s subsidiary and the other named defendants to settle the lawsuit through arbitration in exchange for an amount less than the total damages awarded. Subsequent to negotiations with the Company's insurance carrier, the Company recorded a $2,447 credit to other expenses related to the partial reversal of its previously recorded loss contingency of $3,000 as of March 31, 2017, to reflect the $553 portion of the final settlement paid by the Company during three months ended September 30, 2017. Leasing commitments As of September 30, 2017 , one of the Company’s multi-tenant retail assets is subject to a ground lease. The Company records ground rent expense on a straight-line basis over the term of the lease. The lease requires rental payments or rental payment increases based upon the appraised value of the property at specified dates, increases in pricing indexes, or certain financial calculations based on the operations of the respective property. In addition, the Company has non-cancelable operating leases for office space used in its business. The Company recognized rent expense associated with ground leases of $93 and $160 for the three and nine months ended September 30, 2017 , respectively, and $67 and $242 for the three and nine months ended September 30, 2016, respectively. The Company recognized rent expense associated with office space leases of $527 and $1,198 for the three and nine months ended September 30, 2017 , respectively, and $359 and $1,052 for the three and nine months ended September 30, 2016 , respectively. Contingent consideration In connection with the purchase of The Parke, the Company entered into an agreement with the seller whereby up to $17,129 in additional consideration would become payable to the seller upon rent commencement of certain tenants. On August 25, 2017, the Company closed on a portion of the earn-out, resulting in cash transferred to the seller of $7,415 . The remaining accrued contingent consideration of $9,714 has been included in other liabilities on the consolidated balance sheet as of September 30, 2017 . The Company recognized the contingent consideration related to the asset upon acquisition and included the initial measurement of the contingent considerations in the cost of the acquired assets.
