Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	1. Organization and Description of Business Griffin-American Healthcare REIT III, Inc., a Maryland corporation, was incorporated on January 11, 2013 and therefore, we consider that our date of inception. We were initially capitalized on January 15, 2013 . We invest in a diversified portfolio of real estate properties, focusing primarily on medical office buildings, hospitals, skilled nursing facilities, senior housing and other healthcare-related facilities. We also operate healthcare-related facilities utilizing the structure permitted by the REIT Investment Diversification and Empowerment Act of 2007, which is commonly referred to as a “RIDEA” structure (the provisions of the Internal Revenue Code of 1986, as amended, or the Code, authorizing the RIDEA structure were enacted as part of the Housing and Economic Recovery Act of 2008). We also originate and acquire secured loans and real estate-related investments on an infrequent and opportunistic basis. We generally seek investments that produce current income. We qualified to be taxed as a real estate investment trust, or REIT, under the Code for federal income tax purposes beginning with our taxable year ended December 31, 2014 , and we intend to continue to qualify to be taxed as a REIT. On February 26, 2014, we commenced a best efforts initial public offering, or our initial offering, in which we offered to the public up to $1,900,000,000 in shares of our common stock. As of April 22, 2015, the deregistration date of our initial offering, we had received and accepted subscriptions in our initial offering for 184,930,598 shares of our common stock, or $1,842,618,000 , excluding shares of our common stock issued pursuant to our distribution reinvestment plan, or the DRIP. As of April 22, 2015, a total of $18,511,000 in distributions were reinvested that resulted in 1,948,563 shares of our common stock being issued pursuant to the DRIP portion of our initial offering. On March 25, 2015, we filed a Registration Statement on Form S-3 under the Securities Act of 1933, as amended, or the Securities Act, to register a maximum of $250,000,000 of additional shares of our common stock pursuant to the DRIP, or the Secondary DRIP Offering. The Registration Statement on Form S-3 was automatically effective with the United States Securities and Exchange Commission, or SEC, upon its filing; however, we did not commence offering shares pursuant to the Secondary DRIP Offering until April 22, 2015, following the deregistration of our initial offering. Effective October 5, 2016, we amended and restated the DRIP, or the Amended and Restated DRIP, to amend the price at which shares of our common stock are issued pursuant to the Secondary DRIP Offering. See Note 13, Equity — Distribution Reinvestment Plan, for a further discussion. As of June 30, 2018 , a total of $201,619,000 in distributions were reinvested and 21,691,668 shares of our common stock were issued pursuant to the Secondary DRIP Offering. We conduct substantially all of our operations through Griffin-Am erican Healthcare REIT III Holdings, LP, or our operating partnership. We are externally advised by Griffin-American Healthcare REIT III Advisor, LLC, or Griffin-American Advisor, or our advisor, pursuant to an advisory agreement, or the Advisory Agreement, between us and our advisor.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies The summary of significant accounting policies presented below is designed to assist in understanding our accompanying condensed consolidated financial statements. Such condensed consolidated financial statements and the accompanying notes thereto are the representations of our management, who are responsible for their integrity and objectivity. These accounting policies conform to accounting principles generally accepted in the United States, or GAAP, in all material respects, and have been consistently applied in preparing our accompanying condensed consolidated financial statements. Basis of Presentation Our accompanying condensed consolidated financial statements include our accounts and those of our operating partnership, the wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries in which we have control, as well as any variable interest entities, or VIEs, in which we are the primary beneficiary. We evaluate our ability to control an entity, and whether the entity is a VIE and we are the primary beneficiary, by considering substantive terms of the arrangement and identifying which enterprise has the power to direct the activities of the entity that most significantly impacts the entity’s economic performance as defined in Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 810, Consolidation , or ASC Topic 810. We operate and intend to co ntinue to operate in an umbrella partnership REIT structure in which our operating partnership, or wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries of which we have control, will own substantially all of the interests in properties acquired on our behalf. We ar e the sole general partner of our operating partnership, and as of June 30, 2018 and December 31, 2017 , we owned greater than a 99.99% general partnership interest therein. As of June 30, 2018 and December 31, 2017 , our advisor owned less than a 0.01% limited partnership interest in our operating partnership. Because we are the sole general partner of our operating partnership and have unilateral control over its management and major operating decisions (even if additional limited partners are admitted to our operating partnership), the accounts of our operating partnership are consolidated in our accompanying condensed consolidated financial statements. All intercompany accounts and transactions are eliminated in consolidation. Interim Unaudited Financial Data Our accompanying condensed consolidated financial statements have been prepared by us in accordance with GAAP in conjunction with the rules and regulations of the SEC. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, our accompanying condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. Our accompanying condensed consolidated financial statements reflect all adjustments which are, in our view, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim period. Interim results of operations are not necessarily indicative of the results to be expected for the full year; such full year results may be less favorable. In preparing our accompanying condensed consolidated financial statements, management has evaluated subsequent events through the financial statement issuance date. We believe that although the disclosures contained herein are adequate to prevent the information presented from being misleading, our accompanying condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our 2017 Annual Report on Form 10-K, as filed with the SEC on March 16, 2018. Use of Estimates The preparation of our accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as the disclosure of contingent assets and liabilities, at the date of our condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates are made and evaluated on an on-going basis using information that is currently available as well as various other assumptions believed to be reasonable under the circumstances. Actual results could differ from those estimates, perhaps in material adverse ways, and those estimates could be different under different assumptions or conditions. Revenue Recognition and Tenant and Resident Receivables Resident fees and services Prior to January 1, 2018, we recognized resident fees and services revenue in accordance with ASC Topic 605, Revenue Recognition , or ASC Topic 605. ASC Topic 605 requires that all four of the following basic criteria be met before revenue is realized or realizable and earned: (i) there is persuasive evidence that an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the seller’s price to the buyer is fixed or determinable; and (iv) collectability is reasonably assured. Tenant receivables were placed on nonaccrual status when management determined that collectability was not reasonably assured, and thus such revenue was recognized using the cash basis method. On January 1, 2018, we adopted ASC Topic 606, Revenue from Contracts with Customers, or ASC Topic 606, applying the modified retrospective method. Results for reporting periods beginning after January 1, 2018 are presented under ASC Topic 606, while prior period amounts are not adjusted and continue to be reported under the accounting standards in effect for the prior period. The adoption of ASC Topic 606 did not have a material impact on the measurement nor on the recognition of resident fees and services revenue as of January 1, 2018; therefore, no cumulative adjustment has been made to the opening balance of retained earnings at the beginning of 2018. A significant portion of resident fees and services revenue represents healthcare service revenue that is reported at the amount that reflects the consideration to which we expect to be entitled in exchange for providing patient care. These amounts are due from patients, third-party payors (including health insurers and government programs), other healthcare facilities, and others and includes variable consideration for retroactive revenue adjustments due to settlement of audits, reviews, and investigations. Generally, we bill the patients, third-party payors and other healthcare facilities several days after the services are performed. Revenue is recognized as performance obligations are satisfied. Performance obligations are determined based on the nature of the services provided by us. Revenue for performance obligations satisfied over time is recognized based on actual charges incurred in relation to total expected (or actual) charges. This method provides a depiction of the transfer of services over the term of the performance obligation based on the inputs needed to satisfy the obligation. Generally, performance obligations satisfied over time relate to patients in our integrated senior health campuses receiving long-term healthcare services, including rehabilitation services. We measure the performance obligation from admission into the integrated senior health campus to the point when we are no longer required to provide services to that patient. Revenue for performance obligations satisfied at a point in time is recognized when goods or services are provided and we do not believe it is required to provide additional goods or services to the patient. Generally, performance obligations satisfied at a point in time relate to sales of our pharmaceuticals business or to sales of ancillary supplies. Because all of its performance obligations relate to contracts with a duration of less than one year, we have elected to apply the optional exemption provided in FASB ASC 606-10-50-14(a) and, therefore, are not required to disclose the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period. The performance obligations for these contracts are generally completed within months of the end of the reporting period. We determine the transaction price based on standard charges for goods and services provided, reduced, where applicable, by contractual adjustments provided to third-party payors, implicit price concessions provided to uninsured patients, and estimates of goods to be returned. We also determine the estimates of contractual adjustments based on Medicare and Medicaid pricing tables and historical experience. We determine the estimate of implicit price concessions based on the historical collection experience with each class of payor. Agreements with third-party payors typically provide for payments at amounts less than established charges. A summary of the payment arrangements with major third-party payors follows: • Medicare: Certain healthcare services are paid at prospectively determined rates based on cost-reimbursement methodologies subject to certain limits. • Medicaid: Reimbursements for Medicaid services are generally paid at prospectively determined rates. In the state of Indiana, we participate in an Upper Payment Limit program, or IGT, with various county hospital partners, which provides supplemental Medicaid payments to skilled nursing facilities that are licensed to non-state, government-owned entities such as county hospital districts. We have operational responsibility through management agreements for facilities retained by the county hospital districts including this IGT. • Other: Payment agreements with certain commercial insurance carriers, health maintenance organizations and preferred provider organizations provide for payment using prospectively determined rates per discharge, discounts from established charges and prospectively determined periodic rates. Laws and regulations concerning government programs, including Medicare and Medicaid, are complex and subject to varying interpretation. As a result of investigations by governmental agencies, various healthcare organizations have received requests for information and notices regarding alleged noncompliance with those laws and regulations, which, in some instances, have resulted in organizations entering into significant settlement agreements. Compliance with such laws and regulations may also be subject to future government review and interpretation as well as significant regulatory action, including fines, penalties and potential exclusion from the related programs. There can be no assurance that regulatory authorities will not challenge our compliance with these laws and regulations, and it is not possible to determine the impact (if any) such claims or penalties would have upon us. Settlements with third-party payors for retroactive adjustments due to audits, reviews or investigations are considered variable consideration and are included in the determination of the estimated transaction price for providing patient care. These settlements are estimated based on the terms of the payment agreement with the payor, correspondence from the payor and our historical settlement activity, including an assessment to ensure that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the retroactive adjustment is subsequently resolved. Estimated settlements are adjusted in future periods as adjustments become known (that is, new information becomes available), or as years are settled or are no longer subject to such audits, reviews and investigations. Adjustments arising from a change in the transaction price were not significant for the three and six months ended June 30, 2018 . In accordance with the disclosure requirements of the new revenue standard, the impact of the adoption of ASC Topic 606 on our condensed consolidated statements of operations and comprehensive income (loss) for the three and six months ended June 30, 2018 were as follows: Three Months Ended June 30, 2018 Six Months Ended June 30, 2018 As Reported Balances Without Adoption of ASC Topic 606 Effect of Change Lower As Reported Balances Without Adoption of ASC Topic 606 Effect of Change Lower Resident fees and services $ 247,582,000 $ 249,529,000 $ (1,947,000 ) $ 492,975,000 $ 496,463,000 $ (3,488,000 ) Property operating expenses $ 218,271,000 $ 218,369,000 $ (98,000 ) $ 435,630,000 $ 435,809,000 $ (179,000 ) General and administrative $ 6,622,000 $ 8,420,000 $ (1,798,000 ) $ 13,010,000 $ 16,228,000 $ (3,218,000 ) Net income $ 682,000 $ 733,000 $ (51,000 ) $ 9,107,000 $ 9,198,000 $ (91,000 ) In accordance with the disclosure requirements of the new revenue standard, the impact of the adoption of ASC Topic 606 on our condensed consolidated balance sheet as of June 30, 2018 was as follows: As Reported Balances Without Adoption of ASC Topic 606 Effect of Change Higher/(Lower) Assets Other assets, net $ 110,836,000 $ 110,657,000 $ 179,000 Liabilities Accounts payable and accrued liabilities $ 125,375,000 $ 125,105,000 $ 270,000 Equity Accumulated deficit $ (649,551,000 ) $ (649,460,000 ) $ (91,000 ) The change in reported balances is primarily based on the fact that substantially all of the amounts recorded to bad debt expense pursuant to our previous accounting policy in accordance with ASC Topic 605 are now recorded as direct reductions of resident fees and services revenue as contractual adjustments provided to third-party payors or implicit price concessions pursuant to the new revenue standard, ASC Topic 606. Disaggregation of Resident Fees and Services Revenue We disaggregate revenue from contracts with customers according to lines of business and payor classes. The transfer of goods and services may occur at a point in time or over time; in other words, revenue may be recognized over the course of the underlying contract, or may occur at a single point in time based upon a single transfer of control. This distinction is discussed in further detail below. We determine that disaggregating revenue into these categories achieves the disclosure objective to depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. The following table disaggregates our resident fees and services revenue by line of business, according to whether such revenue is recognized at a point in time or over time: Three Months Ended June 30, 2018 Six Months Ended June 30, 2018 Point in Time Over Time Total Point in Time Over Time Total Integrated senior health campuses $ 44,657,000 $ 186,864,000 $ 231,521,000 $ 89,822,000 $ 370,760,000 $ 460,582,000 Senior housing — RIDEA(1) 729,000 15,332,000 16,061,000 1,497,000 30,896,000 32,393,000 Total resident fees and services $ 45,386,000 $ 202,196,000 $ 247,582,000 $ 91,319,000 $ 401,656,000 $ 492,975,000 The following table disaggregates our resident fees and services revenue by payor class: Three Months Ended June 30, 2018 Six Months Ended June 30, 2018 Integrated Senior Health Campuses Senior Housing — RIDEA(1) Total Integrated Senior Health Campuses Senior Housing — RIDEA(1) Total Medicare $ 76,838,000 $ — $ 76,838,000 $ 132,994,000 $ — $ 132,994,000 Medicaid 40,815,000 — 40,815,000 81,219,000 3,000 81,222,000 Private and other payors 113,868,000 16,061,000 129,929,000 246,369,000 32,390,000 278,759,000 Total resident fees and services $ 231,521,000 $ 16,061,000 $ 247,582,000 $ 460,582,000 $ 32,393,000 $ 492,975,000 ___________ (1) This includes fees for basic housing and assisted living care. We record revenue when services are rendered on the date services are provided at amounts billable to individual residents. Residency agreements are generally for a term of 30 days, with resident fees billed monthly in advance. For patients under reimbursement arrangements with Medicaid, revenue is recorded based on contractually agreed-upon amounts or rates on a per resident, daily basis or as services are rendered. Accounts Receivable, Net — Resident Fees and Services The beginning and ending balances of accounts receivable, net — resident fees and services are as follows: Medicare Medicaid Private and Other Payors Total Beginning balance — January 1, 2018 $ 29,979,000 $ 15,640,000 $ 35,706,000 $ 81,325,000 Ending balance — June 30, 2018 30,698,000 14,276,000 39,322,000 84,296,000 Increase/(decrease) $ 719,000 $ (1,364,000 ) $ 3,616,000 $ 2,971,000 Deferred Revenue — Resident Fees and Services The beginning and ending balances of deferred revenue — resident fees and services, all of which relates to private payors, are as follows: Total Beginning balance — January 1, 2018 $ 9,801,000 Ending balance — June 30, 2018 11,860,000 Increase $ 2,059,000 All amounts included in the beginning balance of deferred revenue — resident fees and services at January 1, 2018 were recognized as revenue during the six months ended June 30, 2018 . Financing Component We have elected the practical expedient allowed under FASB ASC 606-10-32-18 and, therefore, we do not adjust the promised amount of consideration from patients and third-party payors for the effects of a significant financing component due to our expectation that the period between the time the service is provided to a patient and the time that the patient or a third-party payor pays for that service will be one year or less. Contract Costs We have applied the practical expedient provided by FASB ASC 340-40-25-4 and, therefore, all incremental customer contract acquisition costs are expensed as they are incurred since the amortization period of the asset that we otherwise would have recognized is one year or less in duration. Accounts Payable and Accrued Liabilities As of June 30, 2018 and December 31, 2017 , accounts payable and accrued liabilities primarily includes insurance payables of $28,367,000 and $27,208,000 , respectively, reimbursement of payroll related costs to the managers of our senior housing — RIDEA facilities and integrated senior health campuses of $24,099,000 and $23,737,000 , respectively, accrued property taxes of $15,132,000 and $13,406,000 , respectively, accrued capital expenditures to unaffiliated third parties of $10,022,000 and $5,988,000 , respectively, and accrued distributions of $9,898,000 and $10,192,000 , respectively. Statement of Cash Flows For the six months ended June 30, 2017 , amounts totaling $495,102,000 have been removed from borrowings under the lines of credit and term loans and payments on the lines of credit and term loans compared to amounts previously presented. There was no net change in previously disclosed net cash provided by financing activities. Recently Issued Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update, or ASU, 2016-02, Leases , or ASU 2016-02, which amends the guidance on accounting for leases, including extensive amendments to the disclosure requirements. Under ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under ASU 2016-02 from a lessor perspective, the guidance will require bifurcation of lease revenues into lease components and non-lease components and to separately recognize and disclose non-lease components that are executory in nature. Lease components will continue to be recognized on a straight-line basis over the lease term and certain non-lease components may be accounted for under the new revenue recognition guidance in ASC Topic 606. In addition, ASU 2016-02 provides a practical expedient that allows an entity to not reassess the following upon adoption (must be elected as a group): (i) whether an expired or existing contract contains a lease arrangement; (ii) the lease classification related to expired or existing lease arrangements; or (iii) whether costs incurred on expired or existing leases qualify as initial direct costs. We plan to elect this practical expedient. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases , or ASU 2018-10, and ASU 2018-11, Leases (Topic 842) Targeted Improvements , or ASU 2018-11, which updates the guidance on accounting for leases under ASU 2016-02. ASU 2018-10 was issued to increase stockholders’ awareness of narrow aspects of the guidance issued in the amendments and to expedite the improvements under ASU 2016-02. ASU 2018-11 provides (a) an alternative transition method by allowing entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, in addition to the modified retrospective transition method prescribed by ASU 2016-02, which requires application of the new leases standard at the beginning of the earliest period presented in the financial statements for comparative purposes; and (b) a practical expedient that permits lessors to not separate non-lease components from the associated lease component if certain conditions are met. ASU 2016-02, ASU 2018-10 and ASU 2018-11 are effective for fiscal years and interim periods beginning after December 15, 2018. Early adoption is permitted for financial statements that have not yet been made available for issuance. As a result of the adoption of the new leases standard on January 1, 2019, we: (i) will recognize all of our operating leases for which we are the lessee, including facilities leases and ground leases, on our consolidated balance sheets; and (ii) may be required to increase our revenue and expense for the amount of real estate taxes and insurance paid by our tenants under triple-net leases; however, we are still evaluating the complete impact of the adoption of the new leases standard and its related expedients, in addition to the transition method, on January 1, 2019 to our consolidated financial statements and disclosures. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, or ASU 2016-13, which introduces a new approach to estimate credit losses on certain types of financial instruments based on expected losses. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. ASU 2016-13 is effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted after December 15, 2018. We do not expect the adoption of ASU 2016-13 on January 1, 2020 to have a material impact on our consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income , or ASU 2018-02, which amends the reclassification requirements from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017, or the Tax Act. Under ASU 2018-02, an entity will be required to provide certain disclosures regarding stranded tax effects. ASU 2018-02 is effective for fiscal years and interim periods beginning after December 15, 2018. Early adoption is permitted. We do not expect the adoption of ASU 2018-02 on January 1, 2019 to have a material impact on our consolidated financial statements. In March 2018, the FASB issued ASU 2018-05, Amendments to the SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 , or ASU 2018-05, which updates the income tax accounting in GAAP to reflect the SEC’s interpretive guidance with regards to the Tax Act. We adopted ASU 2018-05 in March 2018, which did not have a material impact on our consolidated financial statements. See Note 16, Income Taxes , for a further discussion.

Depreciation expense for the six months ended June 30, 2018 and 2017 was $40,687,000 and $40,842,000 , respectively. For both the three and six months ended June 30, 2018 , we determined that one of our medical office buildings was impaired and recognized an impairment charge of $2,542,000 , which reduced the total carrying value of such investment to $7,387,000 . The fair value of such medical office building was based upon a discounted cash flow analysis where the most significant inputs were market rents, lease absorption rate, capitalization rate and discount rate, and such inputs were considered Level 3 measurements within the fair value hierarchy. For the three and six months ended June 30, 2017 , we recognized impairment charges of $914,000 and $4,883,000 , respectively, related to two integrated senior health campuses. We recognized an aggregate impairment charge of $4,883,000 , which reduced the total carrying value of such investments to $990,000 . The fair values of such integrated senior health campuses were based on their projected sales prices, which were considered to be Level 2 measurements within the fair value hierarchy. For the three months ended June 30, 2018 , we incurred capital expenditures of $14,888,000 on our integrated senior health campuses, $1,624,000 on our medical office buildings, $293,000 on our senior housing — RIDEA facilities, $25,000 on our hospitals and $4,000 on our skilled nursing facilities. We did not incur any capital expenditures on our senior housing facilities for the three months ended June 30, 2018 . For the six months ended June 30, 2018 , we incurred capital expenditures of $27,866,000 on our integrated senior health campuses, $3,543,000 on our medical office buildings, $515,000 on our senior housing — RIDEA facilities, $468,000 on our skilled nursing facilities and $47,000 on our hospitals. We did not incur any capital expenditures on our senior housing facilities for the six months ended June 30, 2018 . We reimburse our advisor or its affiliates for acquisition expenses related to selecting, evaluating and acquiring assets. The reimbursement of acquisition expenses, acquisition fees, total development costs and real estate commissions and other fees paid to unaffiliated third parties will not exceed, in the aggregate, 6.0% of the contract purchase price, unless fees in excess of such limits are approved by a majority of our directors, including a majority of our independent directors. For the three and six months ended June 30, 2018 and 2017 , such fees and expenses noted above did not exceed 6.0% of the contract purchase price of our property acquisitions. Acquisitions in 2018 On April 17, 2018, we purchased land as part of our existing Southern Illinois MOB Portfolio for a contract purchase price of $300,000 . We paid a 2.25% acquisition fee in cash to our advisor of approximately $7,000 , plus closing costs. Completed Developments and/or Expansions in 2018 For the six months ended June 30, 2018 , we incurred $2,323,000 to expand our integrated senior health campuses, which is included in real estate investments, net, in our accompanying condensed consolidated balance sheets.

The Mezzanine Notes only require monthly interest payments and are subject to certain prepayment restrictions if repaid before the respective maturity dates. (4) The commercial mortgage-backed debt security, or debt security, bears an interest rate on the stated principal amount thereof equal to 4.24% per annum, the terms of which security provide for monthly interest-only payments. The debt security matures on August 25, 2025 at a stated amount of $93,433,000 , resulting in an anticipated yield-to-maturity of 10.0% per annum. The debt security was issued by an unaffiliated mortgage trust and represents a 10.0% beneficial ownership interest in such mortgage trust.

As of June 30, 2018 and December 31, 2017 , the net carrying amount with accretion was $68,549,000 and $67,275,000 , respectively. We classify our debt security investment as held-to-maturity and we have not recorded any unrealized holding gains or losses on such investment. We reimburse our advisor or its affiliates for acquisition expenses related to selecting, evaluating and acquiring assets. The reimbursement of acquisition expenses, acquisition fees and real estate commissions and other fees paid to unaffiliated third parties will not exceed, in the aggregate, 6.0% of the contract purchase price or in the case of a loan, funds advanced in a loan, unless fees in excess of such limits are approved by a majority of our directors, including a majority of our independent directors. For the three and six months ended June 30, 2018 and 2017 , such fees and expenses noted above did not exceed 6.0% of the contract purchase price of our real estate-related investments.

The material terms of the Trilogy OpCo Amendment provide for: (i) a reduction in the aggregate maximum principal amount from $60,000,000 to $25,000,000 ; (ii) a reduced floating interest rate based on LIBOR, plus an applicable margin of 2.75% per annum, for LIBOR Rate Loans, as defined in the agreement, or an alternate base rate plus an applicable margin of 1.75% per annum, for Base Rate Loans, as defined in the agreement, at the Trilogy OpCo Borrowers’ option; (iii) a reduced letter of credit fee of 2.75% per annum times the undrawn amount of outstanding letters of credit; and (iv) an updated maturity date of April 27, 2021 . Accrued interest under the Trilogy OpCo Line of Credit is payable monthly. In addition to paying interest on the outstanding principal under the Trilogy OpCo Line of Credit, the Trilogy OpCo Borrowers are required to pay an unused fee in an amount equal to 0.50% per annum times the average monthly unutilized commitment. The unused fee is payable monthly in arrears, commencing on the first day of each month from and after the closing date up to the first day of the month prior to the date on which the obligations are paid in full. If the commitment is terminated prior to the second anniversary of the closing date, a prepayment premium of 1.00% of the total commitment applies. The Trilogy OpCo Credit Agreement, as amended, contains customary events of default, covenants and other terms, including, among other things, restrictions on the payment of dividends and other distributions, incurrence of indebtedness, creation of liens and transactions with affiliates. Availability of the total commitment under the Trilogy OpCo Line of Credit is subject to a borrowing base based on, among other things, the eligible accounts receivable outstanding of the Trilogy OpCo Borrowers. As of June 30, 2018 and December 31, 2017 , our aggregate borrowing capacity under the Trilogy OpCo Line of Credit was $25,000,000 and $60,000,000 , respectively, subject to certain terms and conditions. As of June 30, 2018 and December 31, 2017 , borrowings outstanding under the Trilogy OpCo Line of Credit totaled $9,001,000 and $749,000 , respectively, and the weighted average interest rate on such borrowings outstanding was 4.78% and 5.84% per annum, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure	9. Derivative Financial Instruments Consistent with ASC Topic 815, Derivatives and Hedging , or ASC Topic 815, we record derivative financial instruments in our accompanying condensed consolidated balance sheets as either an asset or a liability measured at fair value. ASC Topic 815 permits special hedge accounting if certain requirements are met. Hedge accounting allows for gains and losses on derivatives designated as hedges to be offset by the change in value of the hedged item or items or to be deferred in other comprehensive income (loss). The following table lists the derivative financial instruments held by us as of June 30, 2018 and December 31, 2017 : Fair Value Instrument Notional Amount Index Interest Rate Maturity Date June 30, 2018 December 31, 2017 Swap $ 140,000,000 one month LIBOR 0.82% 02/03/19 $ 1,203,000 $ 1,486,000 Swap 60,000,000 one month LIBOR 0.78% 02/03/19 529,000 661,000 Swap 50,000,000 one month LIBOR 1.39% 02/03/19 257,000 219,000 $ 250,000,000 $ 1,989,000 $ 2,366,000 As of June 30, 2018 and December 31, 2017 , none of our derivative financial instruments were designated as hedges. Derivative financial instruments not designated as hedges are not speculative and are used to manage our exposure to interest rate movements, but do not meet the strict hedge accounting requirements of ASC Topic 815. Changes in the fair value of derivative financial instruments are recorded as a component of interest expense in gain (loss) in fair value of derivative financial instruments in our accompanying condensed consolidated statements of operations and comprehensive income (loss). For the three months ended June 30, 2018 and 2017 , we recorded $(487,000) and $(233,000) , respectively, and for the six months ended June 30, 2018 and 2017 , we recorded $(377,000) and $103,000 , respectively, as an (increase) decrease to interest expense in our accompanying condensed consolidated statements of operations and comprehensive income (loss) related to the change in the fair value of our derivative financial instruments. See Note 15, Fair Value Measurements , for a further discussion of the fair value of our derivative financial instruments.

Redeemable Noncontrolling Interest	12. Redeemable Noncontrolling Interests On January 15, 2013, our advisor made an initial capital contribution of $2,000 to our operating partnership in exchange for 222 limited partnership units. Upon the effectiveness of the Advisory Agreeme nt on February 26, 2014, Griffin-American Advisor became our advisor. As of June 30, 2018 and December 31, 2017 , we owned greater than a 99.99% general partnership interest in our operating partnership, and our advisor owned less than a 0.01% limited partnership interest in our operating partnership. As our advisor, Griffin-American Advisor is entitled to special redemption rights of its limited partnership units. The noncontrolling interest of our advisor in our operating partnership that has redemption features outside of our control is accounted for as a redeemable noncontrolling interest and is presented outside of permanent equity in our accompanying condensed consolidated balance sheets. See Note 14, Related Party Transactions — Liquidity Stage — Subordinated Participation Interest — Subordinated Distribution Upon Listing and Note 14, Related Party Transactions — Subordinated Distribution Upon Termination, for a further discussion of the redemption features of the limited partnership units. On December 1, 2015, we, through Trilogy REIT Holdings, LLC, or Trilogy REIT Holdings, in which we indirectly hold a 70.0% ownership interest, pursuant to an equity purchase agreement with Trilogy and other seller parties thereto, completed the acquisition of approximately 96.7% of the outstanding equity interests of Trilogy. Pursuant to the equity purchase agreement, at the closing of the acquisition, certain members of Trilogy’s pre-closing management retained a portion of the outstanding equity interests of Trilogy held by such members of Trilogy’s pre-closing management, representing in the aggregate approximately 3.3% of the outstanding equity interests of Trilogy. The noncontrolling interests held by Trilogy’s pre-closing management have redemption features outside of our control and are accounted for as redeemable noncontrolling interests in our accompanying condensed consolidated balance sheets. As of June 30, 2018 , Trilogy REIT Holdings and certain members of Trilogy’s pre-closing management owned approximately 96.7% and 3.3% of Trilogy, respectively. We record the carrying amount of redeemable noncontrolling interests at the greater of: (i) the initial carrying amount, increased or decreased for the noncontrolling interests’ share of net income or loss and distributions or (ii) the redemption value. The changes in the carrying amount of redeemable noncontrolling interests consisted of the following for the six months ended June 30, 2018 and 2017 : Six Months Ended June 30, 2018 2017 Beginning balance $ 32,435,000 $ 31,507,000 Additions 535,000 635,000 Reclassification from equity 390,000 390,000 Distributions (332,000 ) (384,000 ) Repurchase of redeemable noncontrolling interest (229,000 ) (20,000 ) Fair value adjustment to redemption value 293,000 708,000 Net income (loss) attributable to redeemable noncontrolling interests 107,000 (602,000 ) Ending balance $ 33,199,000 $ 32,234,000

Equity	13. Equity Preferred Stock Our charter authorizes us to issue 200,000,000 shares of our preferred stock, par value $0.01 per share. As of June 30, 2018 and December 31, 2017 , no shares of preferred stock were issued and outstanding. Common Stock Our charter authorizes us to issue 1,000,000,000 shares of our common stock, par value $0.01 per share. On January 15, 2013, our advisor acquired 22,222 shares of our common stock for total cash consideration of $200,000 and was admitted as our initial stockholder. We used the proceeds from the sale of shares of our common stock to our advisor to make an initial capital contribution to our operating partnership. On March 12, 2015, we terminated the primary portion of our initial offering. We continued to offer shares of our common stock in our initial offering pursuant to the DRIP, until the termination of the DRIP portion of our initial offering and deregistration of our initial offering on April 22, 2015. On March 25, 2015, we filed a Registration Statement on Form S-3 under the Securities Act to register a maximum of $250,000,000 of additional shares of our common stock pursuant to the Secondary DRIP Offering. The Registration Statement on Form S-3 was automatically effective with the SEC upon its filing; however, we did not commence offering shares pursuant to the Secondary DRIP Offering until April 22, 2015, following the deregistration of our initial offering. Through June 30, 2018 , we had issued 184,930,598 shares of our common stock in connection with the primary portion of our initial offering and 23,640,231 shares of our common stock pursuant to the DRIP and the Secondary DRIP Offering. We also repurchased 9,818,236 shares of our common stock under our share repurchase plan and granted an aggregate of 90,000 shares of our restricted common stock to our independent directors through June 30, 2018 . As of June 30, 2018 and December 31, 2017 , we had 198,864,815 and 199,343,234 shares of our common stock issued and outstanding, respectively. Accumulated Other Comprehensive Loss The changes in accumulated other comprehensive loss, net of noncontrolling interests, by component consisted of the following for the six months ended June 30, 2018 and 2017 : Six Months Ended June 30, 2018 2017 Beginning balance — foreign currency translation adjustments $ (1,971,000 ) $ (3,029,000 ) Net change in current period (238,000 ) 622,000 Ending balance — foreign currency translation adjustments $ (2,209,000 ) $ (2,407,000 ) Noncontrolling Interests As of June 30, 2018 and December 31, 2017 , Trilogy REIT Holdings owned approximately 96.7% of Trilogy. We are the indirect owner of a 70.0% interest in Trilogy REIT Holdings and serve as the sole manager of Trilogy REIT Holdings. NorthStar Healthcare Income, Inc., through certain of its subsidiaries, owns a 30.0% ownership interest in Trilogy REIT Holdings. As of June 30, 2018 and December 31, 2017 , 30.0% of the net earnings of Trilogy REIT Holdings were allocated to noncontrolling interests. In connection with the acquisition and operation of Trilogy, profit interest units in Trilogy, or the Profit Interests, were issued to Trilogy Management Services, LLC and an independent director of Trilogy, both unaffiliated third parties that manage or direct the day-to-day operations of Trilogy. The Profit Interests consist of time-based or performance-based commitments. The time-based Profit Interests were measured at their grant date fair value and vest in increments of 20.0% on each anniversary of the respective grant date over a five -year period. We amortize the time-based Profit Interests on a straight-line basis over the vesting periods, which are recorded to general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). The performance-based Profit Interests are subject to a performance commitment and vest upon liquidity events as defined in the Profit Interests agreements. The performance-based Profit Interests were measured at their grant date fair value and immediately expensed. The performance-based Profit Interests are subject to fair value measurements until vesting occurs with changes to fair value recorded to general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). For the three and six months ended June 30, 2018 we recognized stock compensation expense related to the Profit Interests of $195,000 and $390,000 , respectively. For both the three and six months ended June 30, 2017 , we recognized stock compensation expense related to Profit Interests of $195,000 . There were no canceled, expired or exercised Profit Interests during the six months ended June 30, 2018 and 2017 . The nonvested awards are presented as noncontrolling interests and are re-classified to redeemable noncontrolling interests upon vesting as they have redemption features outside of our control similar to the common stock units held by Trilogy’s pre-closing management once vested. See Note 12, Redeemable Noncontrolling Interests , for a further discussion. On January 6, 2016, one of our consolidated subsidiaries issued non-voting preferred shares of beneficial interests to qualified investors for total proceeds of $125,000 . These preferred shares of beneficial interests are entitled to receive cumulative preferential cash dividends at the rate of 12.5% per annum. In accordance with ASC Topic 810, we classify the value of the subsidiary’s preferred shares of beneficial interests as noncontrolling interests in our accompanying condensed consolidated balance sheets and the dividends of the preferred shares of beneficial interests as net loss attributable to noncontrolling interests in our accompanying condensed consolidated statements of operations and comprehensive income (loss). In addition, as of June 30, 2018 and December 31, 2017 , we owned an 86.0% interest in a consolidated limited liability company that owns Lakeview IN Medical Plaza, which we acquired on January 21, 2016. As such, 14.0% of the net earnings of Lakeview IN Medical Plaza were allocated to noncontrolling interests for the three and six months ended June 30, 2018 and 2017 . Distribution Reinvestment Plan We adopted the DRIP that allowed stockholders to purchase additional shares of our common stock through the reinvestment of distributions at an offering price equal to 95.0% of the primary offering price of our initial offering, subject to certain conditions. We had registered and reserved $35,000,000 in shares of our common stock for sale pursuant to the DRIP in our initial offering at an offering price of $9.50 per share, which we terminated on April 22, 2015. On March 25, 2015, we filed a Registration Statement on Form S-3 under the Securities Act to register a maximum of $250,000,000 of additional shares of our common stock pursuant to the Secondary DRIP Offering. The Registration Statement on Form S-3 was automatically effective with the SEC upon its filing; however, we did not commence offering shares pursuant to the Secondary DRIP Offering until April 22, 2015, following the deregistration of our initial offering. Effective October 5, 2016, the Amended and Restated DRIP amended the price at which shares of our common stock are issued pursuant to the Secondary DRIP Offering. Pursuant to the Amended and Restated DRIP, shares are issued at a price equal to the most recently estimated value of one share of our common stock, as approved and established by our board. The Amended and Restated DRIP became effective with the distribution payment to stockholders paid in the month of November 2016, which distributions were reinvested at $9.01 per share, the initial estimated per share net asset value, or NAV, unanimously approved and established by our board on October 5, 2016. Formerly, shares were issued pursuant to the Secondary DRIP Offering at 95.0% of the estimated value of one share of our common stock, as estimated by our board. In all other material respects, the terms of the Secondary DRIP Offering remain unchanged by the Amended and Restated DRIP. On October 4, 2017, our board approved and established an updated estimated per share NAV of our common stock of $9.27 . Accordingly, commencing with the distribution payment to stockholders paid in the month of November 2017, shares of our common stock issued pursuant to the Amended and Restated DRIP were or will be issued at $9.27 per share, until such time as our board determines a new estimated per share NAV. For the three months ended June 30, 2018 and 2017 , $15,220,000 and $15,946,000 , respectively, in distributions were reinvested that resulted in 1,641,819 and 1,769,786 shares of our common stock, respectively, being issued pursuant to the Secondary DRIP Offering. For the six months ended June 30, 2018 and 2017 , $30,449,000 and $31,627,000 , respectively, in distributions were reinvested that resulted in 3,284,653 and 3,510,170 shares of our common stock, respectively, being issued pursuant to the Secondary DRIP Offering. As of June 30, 2018 and December 31, 2017 , a total of $220,130,000 and $189,681,000 , respectively, in distributions were reinvested that resulted in 23,640,231 and 20,355,578 shares of our common stock, respectively, being issued pursuant to the DRIP portion of our initial offering and the Secondary DRIP Offering. Share Repurchase Plan Our board has approved a share repurchase plan. Our share repurchase plan allows for repurchases of shares of our common stock by us when certain criteria are met. Share repurchases will be made at the sole discretion of our board. Subject to the availability of the funds for share repurchases, we will limit the number of shares of our common stock repurchased during any calendar year to 5.0% of the weighted average number of shares of our common stock outstanding during the prior calendar year; provided, however, that shares subject to a repurchase requested upon the death of a stockholder will not be subject to this cap. Funds for the repurchase of shares of our common stock will come exclusively from the cumulative proceeds we receive from the sale of shares of our common stock pursuant to the DRIP portion of our initial offering and the Secondary DRIP Offering. Furthermore, our share repurchase plan provides that if there are insufficient funds to honor all repurchase requests, pending requests will be honored among all requests for repurchase in any given repurchase period as follows: first, pro rata as to repurchases sought upon a stockholder’s death; next, pro rata as to repurchases sought by stockholders with a qualifying disability; and, finally, pro rata as to other repurchase requests. All repurchases will be subject to a one -year holding period, except for repurchases made in connection with a stockholder’s death or “qualifying disability,” as defined in our share repurchase plan. Further, all share repurchases will be repurchased following a one -year holding period at a price between 92.5% and 100% of each stockholder’s repurchase amount, depending on the period of time their shares have been held. Until October 4, 2016, the repurchase amount for shares repurchased under our share repurchase plan was equal to the lesser of the amount a stockholder paid for their shares of our common stock or the most recent per share offering price. However, if shares of our common stock were repurchased in connection with a stockholder’s death or qualifying disability, the repurchase price was no less than 100% of the price paid to acquire the shares of our common stock from us. Effective with respect to share repurchase requests submitted during the fourth quarter 2016, the Repurchase Amount, as such term is defined in our share repurchase plan, as amended, is equal to the lesser of (i) the amount per share that a stockholder paid for their shares of our common stock, or (ii) the most recent estimated value of one share of our common stock, as determined by our board. Accordingly, commencing with the share repurchase requests submitted during the fourth quarter 2016, we repurchase shares as follows: (a) for stockholders who have continuously held their shares of our common stock for at least one year, the price will be 92.5% of the Repurchase Amount; (b) for stockholders who have continuously held their shares of our common stock for at least two years, the price will be 95.0% of the Repurchase Amount; (c) for stockholders who have continuously held their shares of our common stock for at least three years, the price will be 97.5% of the Repurchase Amount; (d) for stockholders who have held their shares of our common stock for at least four years, the price will be 100% of the Repurchase Amount; and (e) for requests submitted pursuant to a death or a qualifying disability, the price will be 100% of the amount per share the stockholder paid for their shares of common stock (in each case, as adjusted for any stock dividends, combinations, splits, recapitalizations and the like with respect to our common stock). On October 5, 2016, our board approved and established an initial estimated per share NAV of our common stock of $9.01 . Accordingly, commencing with share repurchase requests submitted during the fourth quarter of 2016, the updated estimated per share NAV of $9.01 served as the Repurchase Amount for stockholders who purchased their shares at a price equal to or greater than $9.01 per share in our initial offering, until such time as our board determined a new estimated per share NAV. On October 4, 2017, our board approved and established an updated estimated per share NAV of our common stock of $9.27 . Accordingly, commencing with share repurchase requests submitted during the fourth quarter of 2017, the updated estimated per share NAV of $9.27 has or will serve as the Repurchase Amount for stockholders who purchased their shares at a price equal to or greater than $9.27 per share in our initial offering, until such time as our board determines a new estimated per share NAV. For the three months ended June 30, 2018 and 2017 , we received share repurchase requests and repurchased 1,978,048 and 858,152 shares of our common stock, respectively, for an aggregate of $18,194,000 and $7,577,000 , respectively, at an average repurchase price of $9.20 and $8.83 per share, respectively. For the six months ended June 30, 2018 and 2017 , we received share repurchase requests and repurchased 3,770,572 and 1,660,545 shares of our common stock, respectively, for an aggregate of $34,700,000 and $14,705,000 , respectively, at an average repurchase price of $9.20 and $8.86 per share, respectively. As of June 30, 2018 and December 31, 2017 , we received share repurchase requests and repurchased 9,818,236 and 6,047,664 shares of our common stock, respectively, for an aggregate of $90,058,000 and $55,358,000 , respectively, at an average repurchase price of $9.17 and $9.15 per share, respectively. All shares were repurchased using proceeds we received from the sale of shares of our common stock pursuant to the DRIP portion of our initial offering and the Secondary DRIP Offering. 2013 Incentive Plan We adopted the 2013 Incentive Plan, or our incentive plan, pursuant to which our board or a committee of our independent directors may make grants of options, shares of our common stock, stock purchase rights, stock appreciation rights or other awards to our independent directors, employees and consultants. The maximum number of shares of our common stock that may be issued pursuant to our incentive plan is 2,000,000 shares. For both the three and six months ended June 30, 2018 , we granted an aggregate of 7,500 shares of our restricted common stock, at a weighted average grant date fair value of $9.27 per share, to our independent directors in connection with their re-election to our board. Such shares vest as to 20.0% of the shares on the date of grant and on each of the first four anniversaries of the grant date. For the three months ended June 30, 2018 and 2017 , we recognized stock compensation expense related to the director grants of $56,000 and $57,000 , respectively, and for the six months ended June 30, 2018 and 2017 , we recognized stock compensation expense related to the director grants of $99,000 and $100,000 , respectively. Such stock compensation expense is included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss).

For both the three and six months ended June 30, 2018 , we incurred $45,000 in development fees to our advisor or its affiliates. For the three and six months ended June 30, 2017 , we did no t incur any development fees to our advisor or its affiliates. Reimbursement of Acquisition Expenses We reimburse our advisor or its affiliates for acquisition expenses related to selecting, evaluating and acquiring assets, which are reimbursed regardless of whether an asset is acquired. The reimbursement of acquisition expenses, acquisition fees, total development costs and real estate commissions paid to unaffiliated third parties will not exceed, in the aggregate, 6.0% of the contract purchase price or real estate-related investments, unless fees in excess of such limits are approved by a majority of our directors, including a majority of our independent directors, not otherwise interested in the transaction. For the three and six months ended June 30, 2018 and 2017 , such fees and expenses did not exceed 6.0% of the contract purchase price of our property acquisitions or real estate-related investments. For the three and six months ended June 30, 2018 and 2017 , we did not incur any acquisition expenses to our advisor or its affiliates. Reimbursements of acquisition expenses in connection with the acquisition of properties accounted for as business combinations in accordance with ASC Topic 805 are expensed as incurred and included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Reimbursements of acquisition expenses in connection with the acquisition of properties accounted for as asset acquisitions in accordance with ASU 2017-01 or the acquisition of real estate-related investments are capitalized as part of the associated investments in our accompanying condensed consolidated balance sheets. Operational Stage Asset Management Fee We pay our advisor or its affiliates a monthly fee for services rendered in connection with the management of our assets equal to one-twelfth of 0.75% of average invested assets, subject to our stockholders receiving distributions in an amount equal to 5.0% per annum, cumulative, non-compounded, of invested capital. For such purposes, average invested assets means the average of the aggregate book value of our assets invested in real estate properties and real estate-related investments, before deducting depreciation, amortization, bad debt and other similar non-cash reserves, computed by taking the average of such values at the end of each month during the period of calculation; and invested capital means, for a specified period, the aggregate issue price of shares of our common stock purchased by our stockholders, reduced by distributions of net sales proceeds by us to our stockholders and by any amounts paid by us to repurchase shares of our common stock pursuant to our share repurchase plan. For the three months ended June 30, 2018 and 2017 , we incurred $4,784,000 and $4,695,000 , respectively, and for the six months ended June 30, 2018 and 2017 , we incurred $9,565,000 and $9,341,000 , respectively, in asset management fees to our advisor or its affiliates. Asset management fees are included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Property Management Fee Our advisor or its affiliates may directly serve as property manager of our properties or may sub-contract their property management duties to any third party and provide oversight of such third-party property manager. We pay our advisor or its affiliates a monthly management fee equal to a percentage of the gross monthly cash receipts of such property as follows: (i) a property management oversight fee of 1.0% of the gross monthly cash receipts of any stand-alone, single-tenant, net leased property; (ii) a property management oversight fee of 1.5% of the gross monthly cash receipts of any property that is not a stand-alone, single-tenant, net leased property and for which our advisor or its affiliates provide oversight of a third party that performs the duties of a property manager with respect to such property; or (iii) a fair and reasonable property management fee that is approved by a majority of our directors, including a majority of our independent directors, that is not less favorable to us than terms available from unaffiliated third parties for any property that is not a stand-alone, single-tenant, net leased property and for which our advisor or its affiliates will directly serve as the property manager without sub-contracting such duties to a third party. For the three months ended June 30, 2018 and 2017 , we incurred $583,000 and $575,000 , respectively, and for the six months ended June 30, 2018 and 2017 , we incurred $1,194,000 and $1,172,000 , respectively, in property management fees to our advisor or its affiliates. Property management fees are included in property operating expenses and rental expenses in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Lease Fees We pay our advisor or its affiliates a separate fee for any leasing activities in an amount not to exceed the fee customarily charged in arm’s-length transactions by others rendering similar services in the same geographic area for similar properties as determined by a survey of brokers and agents in such area. Such fee is generally expected to range from 3.0% to 6.0% of the gross revenues generated during the initial term of the lease. For the three months ended June 30, 2018 and 2017 , we incurred $659,000 and $93,000 , respectively, and for the six months ended June 30, 2018 and 2017 , we incurred $728,000 and $120,000 , respectively, in lease fees to our advisor or its affiliates. Lease fees are capitalized as lease commissions and included in other assets, net in our accompanying condensed consolidated balance sheets. Construction Management Fee In the event that our advisor or its affiliates assist with planning and coordinating the construction of any capital or tenant improvements, our advisor or its affiliates are paid a construction management fee of up to 5.0% of the cost of such improvements. For the three months ended June 30, 2018 and 2017 , we incurred $8,000 and $14,000 , respectively, and for the six months ended June 30, 2018 and 2017 , we incurred $14,000 and $18,000 , respectively, in construction management fees to our advisor or its affiliates. Construction management fees are capitalized as part of the associated asset and included in real estate investments, net in our accompanying condensed consolidated balance sheets or are expensed and included in our accompanying condensed consolidated statements of operations and comprehensive income (loss), as applicable. Operating Expenses We reimburse our advisor or its affiliates for operating expenses incurred in rendering services to us, subject to certain limitations. However, we cannot reimburse our advisor or its affiliates at the end of any fiscal quarter for total operating expenses that, in the four consecutive fiscal quarters then ended, exceed the greater of: (i) 2.0% of our average invested assets, as defined in the Advisory Agreement; or (ii) 25.0% of our net income, as defined in the Advisory Agreement, unless our independent directors determined that such excess expenses were justified based on unusual and nonrecurring factors which they deem sufficient. Our operating expenses as a percentage of average invested assets and as a percentage of net income were 0.9% and 17.6% , respectively, for the 12 months ended June 30, 2018 ; therefore, our operating expenses did not exceed the aforementioned limitation. For the three months ended June 30, 2018 and 2017 , our advisor or its affiliates incurred operating expenses on our behalf of $47,000 and $49,000 , respectively, and for the six months ended June 30, 2018 and 2017 , incurred $99,000 and $103,000 , respectively. Operating expenses are generally included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Compensation for Additional Services We pay our advisor and its affiliates for services performed for us other than those required to be rendered by our advisor or its affiliates under the Advisory Agreement. The rate of compensation for these services has to be approved by a majority of our board, including a majority of our independent directors, and cannot exceed an amount that would be paid to unaffiliated third parties for similar services. For the three and six months ended June 30, 2018 and 2017 , our advisor and its affiliates were not compensated for any additional services. Liquidity Stage Disposition Fees For services relating to the sale of one or more properties, we pay our advisor or its affiliates a disposition fee of up to the lesser of 2.0% of the contract sales price or 50.0% of a customary competitive real estate commission given the circumstances surrounding the sale, in each case as determined by our board, including a majority of our independent directors, upon the provision of a substantial amount of the services in the sales effort. The amount of disposition fees paid, when added to the real estate commissions paid to unaffiliated third parties, will not exceed the lesser of the customary competitive real estate commission or an amount equal to 6.0% of the contract sales price. For the three and six months ended June 30, 2018 , we did not incur any disposition fees to our advisor or its affiliates. For the three and six months ended June 30, 2017 , we disposed of one integrated senior health campus and one land parcel within our integrated senior health campus segment. Our advisor agreed to waive the disposition fees of such dispositions that may otherwise have been due to our advisor pursuant to the Advisory Agreement. Our advisor did not receive any additional securities, shares of our stock or any other form of consideration or any repayment as a result of the waiver of such disposition fee. Subordinated Participation Interest Subordinated Distribution of Net Sales Proceeds In the event of liquidation, we will pay our advisor a subordinated distribution of net sales proceeds. The distribution will be equal to 15.0% of the remaining net proceeds from the sales of properties, after distributions to our stockholders, in the aggregate, of: (i) a full return of capital raised from stockholders (less amounts paid to repurchase shares of our common stock pursuant to our share repurchase plan); plus (ii) an annual 7.0% cumulative, non-compounded return on the gross proceeds from the sale of shares of our common stock, as adjusted for distributions of net sales proceeds. Actual amounts to be received depend on the sale prices of properties upon liquidation. For the three and six months ended June 30, 2018 and 2017 , we did not pay any such distributions to our advisor. Subordinated Distribution Upon Listing Upon the listing of shares of our common stock on a national securities exchange, in redemption of our advisor’s limited partnership units, we will pay our advisor a distribution equal to 15.0% of the amount by which: (i) the market value of our outstanding common stock at listing plus distributions paid prior to listing exceeds (ii) the sum of the total amount of capital raised from stockholders (less amounts paid to repurchase shares of our common stock pursuant to our share repurchase plan) and the amount of cash that, if distributed to stockholders as of the date of listing, would have provided them an annual 7.0% cumulative, non-compounded return on the gross proceeds from the sale of shares of our common stock through the date of listing. Actual amounts to be paid depend upon the market value of our outstanding stock at the time of listing, among other factors. For the three and six months ended June 30, 2018 and 2017 , we did not pay any such distributions to our advisor. Subordinated Distribution Upon Termination Pursuant to the Agreement of Limited Partnership, as amended, of our operating partnership, upon termination or non-renewal of the Advisory Agreement, our advisor will also be entitled to a subordinated distribution in redemption of its limited partnership units from our operating partnership equal to 15.0% of the amount, if any, by which: (i) the appraised value of our assets on the termination date, less any indebtedness secured by such assets, plus total distributions paid through the termination date, exceeds (ii) the sum of the total amount of capital raised from stockholders (less amounts paid to repurchase shares of our common stock pursuant to our share repurchase plan) and the total amount of cash equal to an annual 7.0% cumulative, non-compounded return on the gross proceeds from the sale of shares of our common stock through the termination date. In addition, our advisor may elect to defer its right to receive a subordinated distribution upon termination until either a listing or other liquidity event, including a liquidation, sale of substantially all of our assets or merger in which our stockholders receive in exchange for their shares of our common stock, shares of a company that are traded on a national securities exchange. As of June 30, 2018 and 2017 , we did not have any liability related to the subordinated distribution upon termination. Accounts Payable Due to Affiliates The following amounts were outstanding to our affiliates as of June 30, 2018 and December 31, 2017 : Fee June 30, 2018 December 31, 2017 Asset and property management fees $ 1,781,000 $ 1,783,000 Acquisition fees 104,000 115,000 Development fees 34,000 104,000 Lease commissions 33,000 31,000 Operating expenses 10,000 10,000 Construction management fees 6,000 14,000 $ 1,968,000 $ 2,057,000

Fair Value Measurements	15. Fair Value Measurements Assets and Liabilities Reported at Fair Value The table below presents our assets and liabilities measured at fair value on a recurring basis as of June 30, 2018 , aggregated by the level in the fair value hierarchy within which those measurements fall: Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Assets: Derivative financial instruments $ — $ 1,989,000 $ — $ 1,989,000 Contingent consideration receivable — — — — Total assets at fair value $ — $ 1,989,000 $ — $ 1,989,000 Liabilities: Contingent consideration obligations $ — $ — $ 4,618,000 $ 4,618,000 Warrants — — 1,078,000 1,078,000 Total liabilities at fair value $ — $ — $ 5,696,000 $ 5,696,000 The table below presents our assets and liabilities measured at fair value on a recurring basis as of December 31, 2017 , aggregated by the level in the fair value hierarchy within which those measurements fall: Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Assets: Derivative financial instruments $ — $ 2,366,000 $ — $ 2,366,000 Contingent consideration receivable — — — — Total assets at fair value $ — $ 2,366,000 $ — $ 2,366,000 Liabilities: Contingent consideration obligations $ — $ — $ 5,107,000 $ 5,107,000 Warrants — — 1,155,000 1,155,000 Total liabilities at fair value $ — $ — $ 6,262,000 $ 6,262,000 There were no transfers into or out of fair value measurement levels during the six months ended June 30, 2018 and 2017 . Derivative Financial Instruments We use interest rate swaps and interest rate caps to manage interest rate risk associated with variable-rate debt. The valuation of these instruments is determined using widely accepted valuation techniques including a discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, as well as option volatility. The fair values of interest rate swaps are determined by netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates derived from observable market interest rate curves. To comply with the provisions of ASC Topic 820, Fair Value Measurements and Disclosures , or ASC Topic 820, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Although we have determined that the majority of the inputs used to value our derivative financial instruments fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with these instruments utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by us and our counterparty. However, as of June 30, 2018 , we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined that our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. Contingent Consideration Asset As of June 30, 2018 , we have not recorded any contingent consideration receivables. In connection with our acquisition of Mt. Juliet TN MOB in March 2015, there was a contingent consideration receivable in the range of $0 up to a maximum of $634,000 as of the acquisition date. We would have received payment of contingent consideration in the event that a tenant occupying 6,611 square feet of GLA terminated their lease prior to March 31, 2018, and to the extent there was a shortfall in rent from such tenant. As of March 31, 2018, such tenant was current on all rental payments and the lease expired with no amounts due to us. In addition, we were to receive payment of contingent consideration in the event a replacement tenant was not found as of the expiration of the lease of the above mentioned tenant prior to March 31, 2018. As of March 31, 2018, a replacement tenant was not found and, as such, we received consideration of $45,000 in May 2018. Liabilities As of June 30, 2018 and December 31, 2017 , we have accrued $4,618,000 and $5,107,000 , respectively, of contingent consideration obligations in connection with our acquisitions of two senior housing facilities within North Carolina ALF Portfolio in January and June 2015. Such obligations are included in security deposits, prepaid rent and other liabilities in our accompanying condensed consolidated balance sheets and are paid upon various conditions being met, including our tenants achieving certain operating performance metrics. In particular, the amounts will be paid based upon the computation in the lease agreement and receipt of notification within three years after the applicable acquisition date that the tenant has increased its earnings before interest, taxes, depreciation and rent cost, or EBITDAR, as defined in the lease agreement, for the preceding three months. Effective January 2018, the lease agreement was amended to extend the contingent consideration payout period to four years from the original three years for the two facilities with other terms of the amendment remaining consistent with the original lease agreement. There is no minimum required payment, but the total maximum payment is capped at $20,318,000 for the two senior housing facilities and is also limited by the tenant’s ability to increase its EBITDAR. Any payment made will result in an increase in the monthly rent charged to the tenant and additional rental revenue to us. As of June 30, 2018 , we estimate that we will pay the contingent consideration of $4,618,000 for these two facilities within North Carolina ALF Portfolio. Warrants As of June 30, 2018 and December 31, 2017 , we have recorded $1,078,000 and $1,155,000 , respectively, related to warrants in Trilogy common units held by certain members of Trilogy’s pre-closing management, which is included in security deposits, prepaid rent and other liabilities in our accompanying condensed consolidated balance sheets. Once exercised, these warrants have redemption features similar to the common units held by members of Trilogy’s pre-closing management. See Note 12, Redeemable Noncontrolling Interests , for a further discussion. As of June 30, 2018 and December 31, 2017 , the carrying value is a reasonable estimate of fair value. Financial Instruments Disclosed at Fair Value ASC Topic 825, Financial Instruments, requires disclosure of the fair value of financial instruments, whether or not recognized on the face of the balance sheet. Fair value is defined under ASC Topic 820. Our accompanying condensed consolidated balance sheets include the following financial instruments: real estate notes receivable, debt security investment, cash and cash equivalents, accounts and other receivables, restricted cash, real estate deposits, accounts payable and accrued liabilities, accounts payable due to affiliates, mortgage loans payable and borrowings under our lines of credit and term loans. We consider the carrying values of cash and cash equivalents, accounts and other receivables, restricted cash, real estate deposits and accounts payable and accrued liabilities to approximate the fair value for these financial instruments based upon an evaluation of the underlying characteristics, market data and because of the short period of time between origination of the instruments and their expected realization. The fair value of cash and cash equivalents is classified in Level 1 of the fair value hierarchy. The fair value of accounts payable due to affiliates is not determinable due to the related party nature of the accounts payable. The fair values of the other financial instruments are classified in Level 2 of the fair value hierarchy. The fair value of our real estate notes receivable and debt security investment are estimated using a discounted cash flow analysis using interest rates available to us for investments with similar terms and maturities. The fair value of our mortgage loans payable and our lines of credit and term loans are estimated using a discounted cash flow analysis using borrowing rates available to us for debt instruments with similar terms and maturities. We have determined that the valuations of our real estate notes receivable, debt security investment, mortgage loans payable and lines of credit and term loans are classified in Level 2 within the fair value hierarchy. The carrying amounts and estimated fair values of such financial instruments as of June 30, 2018 and December 31, 2017 were as follows: June 30, 2018 December 31, 2017 Carrying Amount Fair Value Carrying Amount Fair Value Financial Assets: Real estate notes receivable $ 30,649,000 $ 31,175,000 $ 30,713,000 $ 31,414,000 Debt security investment $ 68,549,000 $ 93,406,000 $ 67,275,000 $ 94,202,000 Financial Liabilities: Mortgage loans payable $ 610,789,000 $ 549,469,000 $ 613,558,000 $ 570,918,000 Lines of credit and term loans $ 670,367,000 $ 675,457,000 $ 617,798,000 $ 624,102,000

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	16. Income Taxes As a REIT, we generally will not be subject to federal income tax on taxable income that we distribute to our stockholders. We have elected to treat certain of our consolidated subsidiaries as taxable REIT subsidiaries, or TRSs, pursuant to the Code. TRSs may participate in services that would otherwise be considered impermissible for REITs and are subject to federal and state income tax at regular corporate tax rates. On December 22, 2017, the U.S. government enacted comprehensive tax legislation pursuant to the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to, reducing the U.S. federal corporate tax rate from 35.0% to 21.0%, eliminating the corporate alternative minimum tax and changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017 . We adopted ASU 2018-05 which allows us to record provisional amounts during the period of enactment. Any change to the provisional amounts will be recorded as an adjustment to the provision for income taxes in the period the amounts are determined. The measurement period ends when we have obtained, prepared and analyzed the information necessary to finalize the provision, but cannot extend beyond one year of the enactment date. The components of income (loss) before taxes for the three and six months ended June 30, 2018 and 2017 were as follows: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Domestic $ 213,000 $ 1,069,000 $ 8,322,000 $ (6,193,000 ) Foreign (57,000 ) (111,000 ) (112,000 ) (589,000 ) Income (loss) before income taxes $ 156,000 $ 958,000 $ 8,210,000 $ (6,782,000 ) The components of income tax benefit for the three and six months ended June 30, 2018 and 2017 were as follows: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Federal deferred $ (1,146,000 ) $ (1,139,000 ) $ (2,478,000 ) $ (3,482,000 ) State deferred (236,000 ) (116,000 ) (503,000 ) (349,000 ) Foreign deferred — 2,000 — (61,000 ) Foreign current 102,000 85,000 181,000 149,000 Valuation allowances 754,000 603,000 1,903,000 2,965,000 Total income tax benefit $ (526,000 ) $ (565,000 ) $ (897,000 ) $ (778,000 ) Current Income Tax Federal and state income taxes are generally a function of the level of income recognized by our TRSs. Foreign income taxes are generally a function of our income on our real estate and real estate-related investments located in the United Kingdom, or UK, and Isle of Man. Deferred Taxes Deferred income tax is generally a function of the period’s temporary differences (primarily basis differences between tax and financial reporting for real estate assets and equity investments) and generation of tax net operating losses that may be realized in future periods depending on sufficient taxable income. We apply the rules under ASC 740-10, Accounting for Uncertainty in Income Taxes, for uncertain tax positions using a “more likely than not” recognition threshold for tax positions. Pursuant to these rules, we will initially recognize the financial statement effects of a tax position when it is more likely than not, based on the technical merits of the tax position, that such a position will be sustained upon examination by the relevant tax authorities. If the tax benefit meets the “more likely than not” threshold, the measurement of the tax benefit will be based on our estimate of the ultimate tax benefit to be sustained if audited by the taxing authority. As of June 30, 2018 and December 31, 2017 , we did not have any tax benefits or liabilities for uncertain tax positions that we believe should be recognized in our accompanying condensed consolidated financial statements. We assess the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. A valuation allowance is established if we believe it is more likely than not that all or a portion of the deferred tax assets are not realizable. As of June 30, 2018 and December 31, 2017 , our valuation allowance substantially reserves the net deferred tax assets due to inherent uncertainty of future income. We will continue to monitor industry and economic conditions, and our ability to generate taxable income based on our business plan and available tax planning strategies, which would allow us to utilize the tax benefits of the net deferred tax assets and thereby allow us to reverse all, or a portion of, our valuation allowance in the future.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting Disclosure	17. Segment Reporting ASC Topic 280, Segment Reporting , establishes standards for reporting financial and descriptive information about a public entity’s reportable segments. We segregate our operations into reporting segments in order to assess the performance of our business in the same way that management reviews our performance and makes operating decisions. Accordingly, when we acquired our first medical office building in June 2014; senior housing facility in September 2014; hospital in December 2014; senior housing — RIDEA portfolio in May 2015; skilled nursing facilities in October 2015; and integrated senior health campuses in December 2015, we established a new reportable business segment at such time. As of June 30, 2018 , we evaluated our business and made resource allocations based on six reportable business segments: medical office buildings, hospitals, skilled nursing facilities, senior housing, senior housing — RIDEA and integrated senior health campuses. Our medical office buildings are typically leased to multiple tenants under separate leases in each building, thus requiring active management and responsibility for many of the associated operating expenses (although many of these are, or can effectively be, passed through to the tenants). In addition, our medical office buildings segment includes the Mezzanine Notes. Our hospital investments are primarily single-tenant properties that lease the facilities to unaffiliated tenants under triple-net and generally master leases that transfer the obligation for all facility operating costs (including maintenance, repairs, taxes, insurance and capital expenditures) to the tenant. Our skilled nursing facilities and senior housing facilities are similarly structured as our hospital investments. In addition, our senior housing segment includes our debt security investment. Our senior housing — RIDEA properties include senior housing facilities that are owned and operated utilizing a RIDEA structure. Our integrated senior health campuses include a range of assisted living, memory care, independent living, skilled nursing services and certain ancillary businesses. We evaluate performance based upon segment net operating income. We define segment net operating income as total revenues, less property operating expenses and rental expenses, which excludes depreciation and amortization, general and administrative expenses, acquisition related expenses, interest expense, gain (loss) on disposition of real estate investments, impairment of real estate investments, foreign currency gain (loss), other income (expense), loss from unconsolidated entity and income tax benefit (expense) for each segment. We believe that net income (loss), as defined by GAAP, is the most appropriate earnings measurement. However, we believe that segment net operating income serves as an appropriate supplemental performance measure to net income (loss) because it allows investors and our management to measure unlevered property-level operating results and to compare our operating results to the operating results of other real estate companies and between periods on a consistent basis. Interest expense, depreciation and amortization and other expenses not attributable to individual properties are not allocated to individual segments for purposes of assessing segment performance. Non-segment assets primarily consist of corporate assets including cash and cash equivalents, other receivables, deferred financing costs, interest rate swap assets and other assets not attributable to individual properties. Summary information for the reportable segments during the three and six months ended June 30, 2018 and 2017 was as follows: Integrated Senior Health Campuses Senior Housing — RIDEA Medical Office

Concentration of Credit Risk [Abstract]
Concentration of Credit Risk	18. Concentration of Credit Risk Financial instruments that potentially subject us to a concentration of credit risk are primarily real estate notes receivable and debt security investment, cash and cash equivalents, accounts and other receivables, restricted cash and real estate deposits. We are exposed to credit risk with respect to the real estate notes receivable and debt security investment, but we believe collection of the outstanding amount is probable. We believe that the risk is further mitigated as the real estate notes receivable are secured by property and there is a guarantee of completion agreement executed between the parent company of the borrowers and us. Cash and cash equivalents are generally invested in investment-grade, short-term instruments with a maturity of three months or less when purchased. We have cash and cash equivalents in financial institutions that are insured by the Federal Deposit Insurance Corporation, or FDIC. As of June 30, 2018 and December 31, 2017 , we had cash and cash equivalents in excess of FDIC insured limits. We believe this risk is not significant. Concentration of credit risk with respect to accounts receivable from tenants is limited. We perform credit evaluations of prospective tenants and security deposits are obtained at the time of property acquisition and upon lease execution. Based on leases in effect as of June 30, 2018 , properties in one state in the United States accounted for 10.0% or more of our total property portfolio’s annualized base rent or annualized net operating income. Properties located in Indiana accounted for 36.1% of our total property portfolio’s annualized base rent or annualized net operating income. Accordingly, there is a geographic concentration of risk subject to fluctuations in such state’s economy. Based on leases in effect as of June 30, 2018 , our six reportable business segments, integrated senior health campuses, medical office buildings, senior housing — RIDEA, senior housing, skilled nursing facilities and hospitals accounted for 46.7% , 27.8% , 10.0% , 6.0% , 5.6% and 3.9% , respectively, of our total property portfolio’s annualized base rent or annualized net operating income. As of June 30, 2018 , none of our tenants at our properties accounted for 10.0% or more of our total property portfolio’s annualized base rent or annualized net operating income, which is based on contractual base rent from leases in effect inclusive of our senior housing — RIDEA facilities and integrated senior health campuses operations as of June 30, 2018 .

Earnings Per Share [Abstract]
Per Share Data	19. Per Share Data We report earnings (loss) per share pursuant to ASC Topic 260, Earnings per Share . Basic earnings (loss) per share for all periods presented are computed by dividing net income (loss) applicable to common stock by the weighted average number of shares of our common stock outstanding during the period. Net income (loss) applicable to common stock is calculated as net income (loss) attributable to controlling interest less distributions allocated to participating securities of $6,000 for both the three months ended June 30, 2018 and 2017 , and $13,000 and $12,000 , respectively, for the six months ended June 30, 2018 and 2017 . Diluted earnings (loss) per share are computed based on the weighted average number of shares of our common stock and all potentially dilutive securities, if any. Nonvested shares of our restricted common stock and redeemable limited partnership units of our operating partnership are participating securities and give rise to potentially dilutive shares of our common stock. As of June 30, 2018 and 2017 , there were 44,500 and 40,000 nonvested shares, respectively, of our restricted common stock outstanding, but such shares were excluded from the computation of diluted earnings per share because such shares were anti-dilutive during these periods. As of June 30, 2018 and 2017 , there were 222 units of redeemable limited partnership units of our operating partnership outstanding, but such units were also excluded from the computation of diluted earnings per share because such units were anti-dilutive during these periods.

Summary of Significant Accoun27

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Our accompanying condensed consolidated financial statements include our accounts and those of our operating partnership, the wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries in which we have control, as well as any variable interest entities, or VIEs, in which we are the primary beneficiary. We evaluate our ability to control an entity, and whether the entity is a VIE and we are the primary beneficiary, by considering substantive terms of the arrangement and identifying which enterprise has the power to direct the activities of the entity that most significantly impacts the entity’s economic performance as defined in Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 810, Consolidation , or ASC Topic 810. We operate and intend to co ntinue to operate in an umbrella partnership REIT structure in which our operating partnership, or wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries of which we have control, will own substantially all of the interests in properties acquired on our behalf. Because we are the sole general partner of our operating partnership and have unilateral control over its management and major operating decisions (even if additional limited partners are admitted to our operating partnership), the accounts of our operating partnership are consolidated in our accompanying condensed consolidated financial statements. All intercompany accounts and transactions are eliminated in consolidation.
Interim Unaudited Financial Data	Interim Unaudited Financial Data Our accompanying condensed consolidated financial statements have been prepared by us in accordance with GAAP in conjunction with the rules and regulations of the SEC. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, our accompanying condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. Our accompanying condensed consolidated financial statements reflect all adjustments which are, in our view, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim period. Interim results of operations are not necessarily indicative of the results to be expected for the full year; such full year results may be less favorable. In preparing our accompanying condensed consolidated financial statements, management has evaluated subsequent events through the financial statement issuance date. We believe that although the disclosures contained herein are adequate to prevent the information presented from being misleading, our accompanying condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our 2017 Annual Report on Form 10-K, as filed with the SEC on March 16, 2018.
Use of Estimates	Use of Estimates The preparation of our accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as the disclosure of contingent assets and liabilities, at the date of our condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates are made and evaluated on an on-going basis using information that is currently available as well as various other assumptions believed to be reasonable under the circumstances. Actual results could differ from those estimates, perhaps in material adverse ways, and those estimates could be different under different assumptions or conditions.
Revenue Recognition and Tenant and Resident Receivables	Revenue Recognition and Tenant and Resident Receivables Resident fees and services Prior to January 1, 2018, we recognized resident fees and services revenue in accordance with ASC Topic 605, Revenue Recognition , or ASC Topic 605. ASC Topic 605 requires that all four of the following basic criteria be met before revenue is realized or realizable and earned: (i) there is persuasive evidence that an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the seller’s price to the buyer is fixed or determinable; and (iv) collectability is reasonably assured. Tenant receivables were placed on nonaccrual status when management determined that collectability was not reasonably assured, and thus such revenue was recognized using the cash basis method. On January 1, 2018, we adopted ASC Topic 606, Revenue from Contracts with Customers, or ASC Topic 606, applying the modified retrospective method. Results for reporting periods beginning after January 1, 2018 are presented under ASC Topic 606, while prior period amounts are not adjusted and continue to be reported under the accounting standards in effect for the prior period. The adoption of ASC Topic 606 did not have a material impact on the measurement nor on the recognition of resident fees and services revenue as of January 1, 2018; therefore, no cumulative adjustment has been made to the opening balance of retained earnings at the beginning of 2018. A significant portion of resident fees and services revenue represents healthcare service revenue that is reported at the amount that reflects the consideration to which we expect to be entitled in exchange for providing patient care. These amounts are due from patients, third-party payors (including health insurers and government programs), other healthcare facilities, and others and includes variable consideration for retroactive revenue adjustments due to settlement of audits, reviews, and investigations. Generally, we bill the patients, third-party payors and other healthcare facilities several days after the services are performed. Revenue is recognized as performance obligations are satisfied. Performance obligations are determined based on the nature of the services provided by us. Revenue for performance obligations satisfied over time is recognized based on actual charges incurred in relation to total expected (or actual) charges. This method provides a depiction of the transfer of services over the term of the performance obligation based on the inputs needed to satisfy the obligation. Generally, performance obligations satisfied over time relate to patients in our integrated senior health campuses receiving long-term healthcare services, including rehabilitation services. We measure the performance obligation from admission into the integrated senior health campus to the point when we are no longer required to provide services to that patient. Revenue for performance obligations satisfied at a point in time is recognized when goods or services are provided and we do not believe it is required to provide additional goods or services to the patient. Generally, performance obligations satisfied at a point in time relate to sales of our pharmaceuticals business or to sales of ancillary supplies. Because all of its performance obligations relate to contracts with a duration of less than one year, we have elected to apply the optional exemption provided in FASB ASC 606-10-50-14(a) and, therefore, are not required to disclose the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period. The performance obligations for these contracts are generally completed within months of the end of the reporting period. We determine the transaction price based on standard charges for goods and services provided, reduced, where applicable, by contractual adjustments provided to third-party payors, implicit price concessions provided to uninsured patients, and estimates of goods to be returned. We also determine the estimates of contractual adjustments based on Medicare and Medicaid pricing tables and historical experience. We determine the estimate of implicit price concessions based on the historical collection experience with each class of payor. Agreements with third-party payors typically provide for payments at amounts less than established charges. A summary of the payment arrangements with major third-party payors follows: • Medicare: Certain healthcare services are paid at prospectively determined rates based on cost-reimbursement methodologies subject to certain limits. • Medicaid: Reimbursements for Medicaid services are generally paid at prospectively determined rates. In the state of Indiana, we participate in an Upper Payment Limit program, or IGT, with various county hospital partners, which provides supplemental Medicaid payments to skilled nursing facilities that are licensed to non-state, government-owned entities such as county hospital districts. We have operational responsibility through management agreements for facilities retained by the county hospital districts including this IGT. • Other: Payment agreements with certain commercial insurance carriers, health maintenance organizations and preferred provider organizations provide for payment using prospectively determined rates per discharge, discounts from established charges and prospectively determined periodic rates. Laws and regulations concerning government programs, including Medicare and Medicaid, are complex and subject to varying interpretation. As a result of investigations by governmental agencies, various healthcare organizations have received requests for information and notices regarding alleged noncompliance with those laws and regulations, which, in some instances, have resulted in organizations entering into significant settlement agreements. Compliance with such laws and regulations may also be subject to future government review and interpretation as well as significant regulatory action, including fines, penalties and potential exclusion from the related programs. There can be no assurance that regulatory authorities will not challenge our compliance with these laws and regulations, and it is not possible to determine the impact (if any) such claims or penalties would have upon us. Settlements with third-party payors for retroactive adjustments due to audits, reviews or investigations are considered variable consideration and are included in the determination of the estimated transaction price for providing patient care. These settlements are estimated based on the terms of the payment agreement with the payor, correspondence from the payor and our historical settlement activity, including an assessment to ensure that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the retroactive adjustment is subsequently resolved. Estimated settlements are adjusted in future periods as adjustments become known (that is, new information becomes available), or as years are settled or are no longer subject to such audits, reviews and investigations. Adjustments arising from a change in the transaction price were not significant for the three and six months ended June 30, 2018 . In accordance with the disclosure requirements of the new revenue standard, the impact of the adoption of ASC Topic 606 on our condensed consolidated statements of operations and comprehensive income (loss) for the three and six months ended June 30, 2018 were as follows: Three Months Ended June 30, 2018 Six Months Ended June 30, 2018 As Reported Balances Without Adoption of ASC Topic 606 Effect of Change Lower As Reported Balances Without Adoption of ASC Topic 606 Effect of Change Lower Resident fees and services $ 247,582,000 $ 249,529,000 $ (1,947,000 ) $ 492,975,000 $ 496,463,000 $ (3,488,000 ) Property operating expenses $ 218,271,000 $ 218,369,000 $ (98,000 ) $ 435,630,000 $ 435,809,000 $ (179,000 ) General and administrative $ 6,622,000 $ 8,420,000 $ (1,798,000 ) $ 13,010,000 $ 16,228,000 $ (3,218,000 ) Net income $ 682,000 $ 733,000 $ (51,000 ) $ 9,107,000 $ 9,198,000 $ (91,000 ) In accordance with the disclosure requirements of the new revenue standard, the impact of the adoption of ASC Topic 606 on our condensed consolidated balance sheet as of June 30, 2018 was as follows: As Reported Balances Without Adoption of ASC Topic 606 Effect of Change Higher/(Lower) Assets Other assets, net $ 110,836,000 $ 110,657,000 $ 179,000 Liabilities Accounts payable and accrued liabilities $ 125,375,000 $ 125,105,000 $ 270,000 Equity Accumulated deficit $ (649,551,000 ) $ (649,460,000 ) $ (91,000 ) The change in reported balances is primarily based on the fact that substantially all of the amounts recorded to bad debt expense pursuant to our previous accounting policy in accordance with ASC Topic 605 are now recorded as direct reductions of resident fees and services revenue as contractual adjustments provided to third-party payors or implicit price concessions pursuant to the new revenue standard, ASC Topic 606. Disaggregation of Resident Fees and Services Revenue We disaggregate revenue from contracts with customers according to lines of business and payor classes. The transfer of goods and services may occur at a point in time or over time; in other words, revenue may be recognized over the course of the underlying contract, or may occur at a single point in time based upon a single transfer of control. This distinction is discussed in further detail below. We determine that disaggregating revenue into these categories achieves the disclosure objective to depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. The following table disaggregates our resident fees and services revenue by line of business, according to whether such revenue is recognized at a point in time or over time: Three Months Ended June 30, 2018 Six Months Ended June 30, 2018 Point in Time Over Time Total Point in Time Over Time Total Integrated senior health campuses $ 44,657,000 $ 186,864,000 $ 231,521,000 $ 89,822,000 $ 370,760,000 $ 460,582,000 Senior housing — RIDEA(1) 729,000 15,332,000 16,061,000 1,497,000 30,896,000 32,393,000 Total resident fees and services $ 45,386,000 $ 202,196,000 $ 247,582,000 $ 91,319,000 $ 401,656,000 $ 492,975,000 The following table disaggregates our resident fees and services revenue by payor class: Three Months Ended June 30, 2018 Six Months Ended June 30, 2018 Integrated Senior Health Campuses Senior Housing — RIDEA(1) Total Integrated Senior Health Campuses Senior Housing — RIDEA(1) Total Medicare $ 76,838,000 $ — $ 76,838,000 $ 132,994,000 $ — $ 132,994,000 Medicaid 40,815,000 — 40,815,000 81,219,000 3,000 81,222,000 Private and other payors 113,868,000 16,061,000 129,929,000 246,369,000 32,390,000 278,759,000 Total resident fees and services $ 231,521,000 $ 16,061,000 $ 247,582,000 $ 460,582,000 $ 32,393,000 $ 492,975,000 ___________ (1) This includes fees for basic housing and assisted living care. We record revenue when services are rendered on the date services are provided at amounts billable to individual residents. Residency agreements are generally for a term of 30 days, with resident fees billed monthly in advance. For patients under reimbursement arrangements with Medicaid, revenue is recorded based on contractually agreed-upon amounts or rates on a per resident, daily basis or as services are rendered. Accounts Receivable, Net — Resident Fees and Services The beginning and ending balances of accounts receivable, net — resident fees and services are as follows: Medicare Medicaid Private and Other Payors Total Beginning balance — January 1, 2018 $ 29,979,000 $ 15,640,000 $ 35,706,000 $ 81,325,000 Ending balance — June 30, 2018 30,698,000 14,276,000 39,322,000 84,296,000 Increase/(decrease) $ 719,000 $ (1,364,000 ) $ 3,616,000 $ 2,971,000 Deferred Revenue — Resident Fees and Services The beginning and ending balances of deferred revenue — resident fees and services, all of which relates to private payors, are as follows: Total Beginning balance — January 1, 2018 $ 9,801,000 Ending balance — June 30, 2018 11,860,000 Increase $ 2,059,000 All amounts included in the beginning balance of deferred revenue — resident fees and services at January 1, 2018 were recognized as revenue during the six months ended June 30, 2018 . Financing Component We have elected the practical expedient allowed under FASB ASC 606-10-32-18 and, therefore, we do not adjust the promised amount of consideration from patients and third-party payors for the effects of a significant financing component due to our expectation that the period between the time the service is provided to a patient and the time that the patient or a third-party payor pays for that service will be one year or less. Contract Costs We have applied the practical expedient provided by FASB ASC 340-40-25-4 and, therefore, all incremental customer contract acquisition costs are expensed as they are incurred since the amortization period of the asset that we otherwise would have recognized is one year or less in duration.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update, or ASU, 2016-02, Leases , or ASU 2016-02, which amends the guidance on accounting for leases, including extensive amendments to the disclosure requirements. Under ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under ASU 2016-02 from a lessor perspective, the guidance will require bifurcation of lease revenues into lease components and non-lease components and to separately recognize and disclose non-lease components that are executory in nature. Lease components will continue to be recognized on a straight-line basis over the lease term and certain non-lease components may be accounted for under the new revenue recognition guidance in ASC Topic 606. In addition, ASU 2016-02 provides a practical expedient that allows an entity to not reassess the following upon adoption (must be elected as a group): (i) whether an expired or existing contract contains a lease arrangement; (ii) the lease classification related to expired or existing lease arrangements; or (iii) whether costs incurred on expired or existing leases qualify as initial direct costs. We plan to elect this practical expedient. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases , or ASU 2018-10, and ASU 2018-11, Leases (Topic 842) Targeted Improvements , or ASU 2018-11, which updates the guidance on accounting for leases under ASU 2016-02. ASU 2018-10 was issued to increase stockholders’ awareness of narrow aspects of the guidance issued in the amendments and to expedite the improvements under ASU 2016-02. ASU 2018-11 provides (a) an alternative transition method by allowing entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, in addition to the modified retrospective transition method prescribed by ASU 2016-02, which requires application of the new leases standard at the beginning of the earliest period presented in the financial statements for comparative purposes; and (b) a practical expedient that permits lessors to not separate non-lease components from the associated lease component if certain conditions are met. ASU 2016-02, ASU 2018-10 and ASU 2018-11 are effective for fiscal years and interim periods beginning after December 15, 2018. Early adoption is permitted for financial statements that have not yet been made available for issuance. As a result of the adoption of the new leases standard on January 1, 2019, we: (i) will recognize all of our operating leases for which we are the lessee, including facilities leases and ground leases, on our consolidated balance sheets; and (ii) may be required to increase our revenue and expense for the amount of real estate taxes and insurance paid by our tenants under triple-net leases; however, we are still evaluating the complete impact of the adoption of the new leases standard and its related expedients, in addition to the transition method, on January 1, 2019 to our consolidated financial statements and disclosures. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, or ASU 2016-13, which introduces a new approach to estimate credit losses on certain types of financial instruments based on expected losses. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. ASU 2016-13 is effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted after December 15, 2018. We do not expect the adoption of ASU 2016-13 on January 1, 2020 to have a material impact on our consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income , or ASU 2018-02, which amends the reclassification requirements from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017, or the Tax Act. Under ASU 2018-02, an entity will be required to provide certain disclosures regarding stranded tax effects. ASU 2018-02 is effective for fiscal years and interim periods beginning after December 15, 2018. Early adoption is permitted. We do not expect the adoption of ASU 2018-02 on January 1, 2019 to have a material impact on our consolidated financial statements. In March 2018, the FASB issued ASU 2018-05, Amendments to the SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 , or ASU 2018-05, which updates the income tax accounting in GAAP to reflect the SEC’s interpretive guidance with regards to the Tax Act. We adopted ASU 2018-05 in March 2018, which did not have a material impact on our consolidated financial statements. See Note 16, Income Taxes , for a further discussion.

(2) The Mezzanine Fixed Rate Notes and the Mezzanine Floating Rate Notes, or collectively, the Mezzanine Notes, evidence interests in a portion of a mezzanine loan that is secured by pledges of equity interests in the owners of a portfolio of domestic healthcare properties, which such owners are themselves owned indirectly by a non-wholly owned subsidiary of Colony Capital. The maturity date of the Mezzanine Floating Rate Notes may be extended by three successive one -year extension periods at the borrower’s option, subject to the satisfaction of certain conditions. In November 2017, the borrower last exercised its right to extend the maturity date of the Mezzanine Floating Rate Notes for one year, to December 2018. (3) Balance represents the original principal balance, decreased by any subsequent principal paydowns. The Mezzanine Notes only require monthly interest payments and are subject to certain prepayment restrictions if repaid before the respective maturity dates. (4) The commercial mortgage-backed debt security, or debt security, bears an interest rate on the stated principal amount thereof equal to 4.24% per annum, the terms of which security provide for monthly interest-only payments. The debt security matures on August 25, 2025 at a stated amount of $93,433,000 , resulting in an anticipated yield-to-maturity of 10.0% per annum. The debt security was issued by an unaffiliated mortgage trust and represents a 10.0% beneficial ownership interest in such mortgage trust. The debt security is subordinate to all other interests in the mortgage trust and is not guaranteed by a government-sponsored entity. As of June 30, 2018 and December 31, 2017 , the net carrying amount with accretion was $68,549,000 and $67,275,000 , respectively. We classify our debt security investment as held-to-maturity and we have not recorded any unrealized holding gains or losses on such investment.

We estimated the fair value of this purchase option asset by discounting the difference between the property’s acquisition date fair value and an estimate of its future option price. We do not amortize the resulting intangible asset over the term of the lease, but rather adjust the recognized value of the asset upon purchase.
