Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business	Business Overview Healthpeak Properties, Inc., a Standard & Poor’s 500 company, is a Maryland corporation that is organized to qualify as a real estate investment trust (“REIT”) which, together with its consolidated entities (collectively, “Healthpeak” or the “Company”), invests primarily in real estate serving the healthcare industry in the United States (“U.S.”). Healthpeak TM acquires, develops, leases, owns, and manages healthcare real estate. The Company’s diverse portfolio is comprised of investments in the following reportable healthcare segments: (i) senior housing triple-net; (ii) senior housing operating portfolio (“SHOP”); (iii) continuing care retirement community (“CCRC”); (iv) life science; and (v) medical office. COVID-19 Update In March 2020, the World Health Organization declared the outbreak caused by the coronavirus (“COVID-19”) to be a global pandemic. While COVID-19 continues to evolve daily and its ultimate outcome is uncertain, it has caused significant disruption to individuals, governments, financial markets, and businesses, including the Company. Global health concerns and increased efforts to reduce the spread of the COVID-19 pandemic have prompted federal, state, and local governments to restrict normal daily activities, and have resulted in travel bans, quarantines, school closings, “shelter-in-place” orders requiring individuals to remain in their homes other than to conduct essential services or activities, as well as business limitations and shutdowns, which resulted in closure of many businesses deemed to be non-essential. In addition, the Company’s tenants, operators and borrowers are facing significant cost increases as a result of increased health and safety measures, including increased staffing demands for patient care and sanitation, as well as increased usage and inventory of critical medical supplies and personal protective equipment. These health and safety measures, which may remain in place for a significant amount of time, continue to place a substantial strain on the business operations of many of the Company’s tenants, operators, and borrowers. The Company evaluated the impacts of COVID-19 on its business thus far and incorporated information concerning the impact of COVID-19 into its assessments of liquidity, impairments, and collectibility from tenants, residents, and borrowers as of June 30, 2020 . The Company will continue to monitor such impacts and will adjust its estimates and assumptions based on the best available information.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Management is required to make estimates and assumptions in the preparation of financial statements in conformity with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from management’s estimates. The consolidated financial statements include the accounts of Healthpeak Properties, Inc., its wholly-owned subsidiaries, joint ventures (“JVs”), and variable interest entities (“VIEs”) that it controls through voting rights or other means. Intercompany transactions and balances have been eliminated upon consolidation. All adjustments (consisting of normal recurring adjustments) necessary to present fairly the Company’s financial position, results of operations, and cash flows have been included. Operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020 . The accompanying unaudited interim financial information should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2019 included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”). Government Grant Income On March 27, 2020, the federal government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) to provide financial aid to individuals, businesses, and state and local governments. During the three and six months ended June 30, 2020 , the Company received government grants under the CARES Act of $15 million to primarily cover lost Medicare revenue during the COVID-19 pandemic. Grant income is recognized when there is reasonable assurance that the grant will be received and the Company will comply with any conditions attached to the grant. Additionally, grants are recognized over the periods in which the Company recognizes the lost income the grants are intended to defray. As of June 30, 2020 , the amount of qualifying expenditures and lost revenues exceeded amounts received under the CARES Act and the Company had complied with all grant conditions. Accordingly, during the three months ended June 30, 2020 , the Company recognized $14 million of grants in other income (expense), net and $1 million of grants in equity income (loss) from unconsolidated joint ventures in the consolidated statements of operations. Segment Reporting The Company’s reportable segments, based on how it evaluates its business and allocates resources, are as follows: (i) senior housing triple-net, (ii) SHOP, (iii) CCRC, (iv) life science, and (v) medical office. In January 2020, primarily as a result of: (i) consolidating 13 of 15 CCRCs previously held by a CCRC joint venture (see discussion of the Brookdale 2019 Master Transaction and Cooperation Agreement in Note 3) and (ii) deconsolidating 19 SHOP assets into a new joint venture in December 2019, the Company's chief operating decision makers (“CODMs”) began reviewing operating results of CCRCs on a stand-alone basis and financial information for each respective segment inclusive of the Company’s share of unconsolidated joint ventures and exclusive of noncontrolling interests’ share of consolidated joint ventures. Therefore, during the first quarter of 2020, the Company began reporting CCRCs as a separate segment and segment measures inclusive of the Company’s share of unconsolidated joint ventures and exclusive of noncontrolling interests’ share of consolidated joint ventures. Accordingly, all prior period segment information has been recast to conform to the current period presentation. Recent Accounting Pronouncements Adopted Leases. In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 (codified under Accounting Standards Codification (“ASC”) 842, Leases ) amends the previous accounting for leases to: (i) require lessees to put most leases on their balance sheets (not required for short-term leases with lease terms of 12 months or less), but continue recognizing expenses on their income statements in a manner similar to requirements under prior accounting guidance, (ii) eliminate real estate specific lease provisions, and (iii) modify the classification criteria and accounting for sales-type leases for lessors. Additionally, ASU 2016-02 provides a practical expedient, which the Company elected, 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) lease classification related to expired or existing lease arrangements, or (iii) whether costs incurred on expired or existing leases qualify as initial direct costs. As a result of adopting ASU 2016-02 on January 1, 2019 using the modified retrospective transition approach, the Company recognized a cumulative-effect adjustment to equity of $1 million as of January 1, 2019. Under ASU 2016-02, the Company began capitalizing fewer costs related to the drafting and negotiation of its lease agreements. Additionally, the Company began recognizing all of its significant operating leases for which it is the lessee, including corporate office leases, equipment leases, and ground leases, on its consolidated balance sheets as a lease liability and corresponding right-of-use asset. As such, the Company recognized a lease liability of $153 million and right-of-use asset of $166 million on January 1, 2019. The aggregate lease liability was calculated as the present value of minimum lease payments, discounted using a rate that approximated the Company’s secured incremental borrowing rate at the time of adoption, adjusted for the noncancelable term of each lease. The right-of-use asset was calculated as the aggregate lease liability, adjusted for the existing accrued straight-line rent liability balance of $20 million and net unamortized above/below market ground lease intangible assets of $33 million . Other. E ffective January 1, 2019, the Company adopted ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”). The amendments in ASU 2017-12 expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. For cash flow and net investment hedges existing at the date of adoption, the Company adopted the amendments in ASU 2017-12 using the modified retrospective approach. For amendments impacting presentation and disclosure, the Company adopted ASU 2017-12 using a prospective approach. The adoption of ASU 2017-12 did not have a material impact to the Company’s consolidated financial position, results of operations, cash flows, or disclosures. Credit Losses. In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 is intended to improve financial reporting by requiring timelier recognition of credit losses on loans and other financial instruments held by financial institutions and other organizations. The amendments in ASU 2016-13 eliminate the “probable” initial threshold for recognition of credit losses in previous accounting guidance and, instead, reflect an entity’s current estimate of all expected credit losses over the life of the financial instrument. Historically, when credit losses were measured under previous accounting guidance, an entity generally only considered past events and current conditions in measuring the incurred loss. The amendments in ASU 2016-13 broaden the information that an entity must consider in developing its expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss. As a result of adopting ASU 2016-13 on January 1, 2020 using the modified retrospective transition approach, the Company recognized a cumulative-effect adjustment to equity of $2 million as of January 1, 2020. Under ASU 2016-13, the Company began using a loss model that relies on future expected credit losses, rather than incurred losses, as was required under historical GAAP. Under the new model, the Company is required to recognize future credit losses expected to be incurred over the life of its financing receivables, including loans receivable, direct financing leases (“DFLs”), and certain accounts receivable, at inception of those instruments. The model emphasizes historical experience and future market expectations to determine a loss to be recognized at inception. However, the model continues to be applied on an individual basis and rely on counter-party specific information to ensure the most accurate estimate is recognized. The Company will reassess its reserves on financing receivables at each balance sheet date to determine if an adjustment to the previous reserve is necessary. Accounting for Lease Concessions Related to COVID-19. In April 2020, the FASB staff issued a question-and-answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of COVID-19. Under ASC 842, the Company would have to determine, on a lease-by-lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A allows the Company, if certain criteria have been met, to bypass the lease-by-lease analysis, and instead elect to either apply the lease modification accounting framework or not, with such election applied consistently to leases with similar characteristics and similar circumstances. During the six months ended June 30, 2020 , the Company provided rent deferrals (to be repaid before the end of 2020) to certain tenants in its life science and medical office segments that were impacted by COVID-19 (discussed in further detail in Note 5). As it relates to these deferrals, the Company elected to not assess them on a lease-by-lease basis and to continue recognizing rent revenue on a straight-line basis. While the Company’s election for rent deferrals will be applied consistently to future deferrals of a similar nature, if the Company grants future lease concessions of a different type (such as rent abatements), it will make an election related to those concessions at that time.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Master Transactions and Cooperation Agreement with Brookdale	Master Transactions and Cooperation Agreement with Brookdale 2019 Master Transactions and Cooperation Agreement with Brookdale In October 2019, the Company and Brookdale Senior Living Inc. (“Brookdale”) entered into a Master Transactions and Cooperation Agreement (the “2019 MTCA”), which includes a series of transactions related to its previously jointly owned 15 -campus CCRC portfolio (the “CCRC JV”) and the portfolio of senior housing properties Brookdale triple-net leased from the Company, which, at the time, included 43 properties. In connection with the 2019 MTCA, the Company and Brookdale, and certain of their respective subsidiaries, closed the following transactions related to the CCRC JV on January 31, 2020: • The Company, which owned a 49% interest in the CCRC JV, purchased Brookdale’s 51% interest in 13 of the 15 communities in the CCRC JV based on a valuation of $1.06 billion (the “CCRC Acquisition”); • The management agreements related to the CCRC Acquisition communities were terminated and management transitioned (under new management agreements) from Brookdale to Life Care Services LLC (“LCS”); and • The Company paid a $100 million management termination fee to Brookdale. In addition, pursuant to the 2019 MTCA, the Company and Brookdale closed the following transactions related to properties Brookdale triple-net leased from the Company on January 31, 2020: • Brookdale acquired 18 of the properties from the Company (the “Brookdale Acquisition Assets”) for cash proceeds of $385 million ; • The remaining 24 properties (excludes one property to be transitioned or sold to a third party, as discussed below) were restructured into a single master lease with 2.4% annual rent escalators and a maturity date of December 31, 2027 (the “2019 Amended Master Lease”); • A portion of annual rent (amount in excess of 6.5% of sales proceeds) related to 14 of the 18 Brookdale Acquisition Assets was reallocated to the remaining properties under the 2019 Amended Master Lease; and • Brookdale paid down $20 million of future rent under the 2019 Amended Master Lease. Additionally, under the 2019 MTCA, the Company and Brookdale agreed to the following transactions which have not yet occurred: • The remaining two CCRCs will be jointly marketed for sale to third parties. • The Company will terminate the triple-net lease related to one property and convert it to a RIDEA structure or sell it to a third party; and • The Company will provide up to $35 million of capital investment in the 2019 Amended Master Lease properties over a five-year term, which will increase rent by 7% of the amount spent, per annum. As of June 30, 2020 , the Company had funded $3 million of this capital investment. As a result of the above transactions, on January 31, 2020, the Company began consolidating the 13 CCRCs in which it acquired Brookdale’s interest. Accordingly, the Company derecognized its investment in the CCRC JV of $323 million and recognized a gain upon change of control of $170 million , which is included in other income (expense), net. In connection with consolidating the 13 CCRCs during the first quarter of 2020, the Company recognized real estate and intangible assets of $1.8 billion , refundable entrance fee liabilities of $308 million , contractual liabilities associated with previously collected non-refundable entrance fees of $436 million , debt assumed of $215 million , other net assets of $48 million , and cash paid of $396 million . Upon sale of the 18 triple-net assets to Brookdale, the Company recognized an aggregate gain on sales of real estate of $164 million . Fair Value Measurement Techniques and Quantitative Information At January 31, 2020, the Company performed a fair value assessment of each of the 2019 MTCA components that provided measurable economic benefit or detriment to the Company. Each fair value calculation was based on an income or market approach and relied on historical and forecasted net operating income, actuarial assumptions about the expected resident length of stay, and market data, including, but not limited to, discount rates ranging from 10% to 12% , annual rent escalators ranging from 2% to 3% , and real estate capitalization rates ranging from 7% to 9% . All assumptions were supported by independent market data and considered to be Level 3 measurements within the fair value hierarchy. 2017 MTCA with Brookdale In November 2017, the Company and Brookdale entered into a Master Transactions and Cooperation Agreement (the “2017 MTCA”) to provide the Company with the ability to significantly reduce its concentration of assets leased to and/or managed by Brookdale. In connection with the overall transaction pursuant to the 2017 MTCA, the Company and Brookdale, and certain of their respective subsidiaries, agreed to the following: • The Company, which owned 90% of the interests in its RIDEA I and RIDEA III joint ventures with Brookdale at the time the 2017 MTCA was executed, agreed to purchase Brookdale’s 10% noncontrolling interest in each joint venture. At the time the 2017 MTCA was executed, these joint ventures collectively owned and operated 58 independent living, assisted living, memory care, and/or skilled nursing facilities (the “RIDEA Facilities”). The Company completed its acquisitions of the RIDEA III noncontrolling interest for $32 million in December 2017 and the RIDEA I noncontrolling interest for $63 million in March 2018; • The Company received the right to sell, or transition to other operators, 32 of the 78 total assets under an Amended and Restated Master Lease and Security Agreement (the “2017 Amended Master Lease”) with Brookdale and 36 of the RIDEA Facilities (and terminate related management agreements with an affiliate of Brookdale without penalty), certain of which were sold during 2018 and 2019; • The Company provided an aggregate $5 million annual reduction in rent on three assets, effective January 1, 2018; and • Brookdale agreed to purchase two of the assets under the 2017 Amended Master Lease for $35 million and four of the RIDEA Facilities for $240 million , all of which were sold in 2018. During 2018, the Company terminated the previous management agreements or leases with Brookdale on 37 assets contemplated under the 2017 MTCA and completed the transition of 20 SHOP assets and 17 senior housing triple-net assets to other managers.

The Company consolidates each DownREIT joint venture. As part of the May and July 2019 Oakmont transactions, the Company assumed $50 million and $112 million , respectively, of secured mortgage debt, both of which were recorded at their relative fair values through asset acquisition accounting. Sierra Point Towers Acquisition In June 2019, the Company acquired two life science buildings in South San Francisco, California, adjacent to the Company’s The Shore at Sierra Point development, for $245 million . Vintage Park JV Interest Purchase In June 2019, the Company acquired the outstanding equity interests of a senior housing joint venture structure (which owned one senior housing facility), in which the Company previously held an unconsolidated equity investment, for $24 million . Subsequent to acquisition, the Company owned 100% of the equity. Upon consolidating the facility at acquisition, the Company derecognized the existing investment in the joint venture structure, marked the real estate to fair value (using a relative fair value allocation), and recognized a gain upon change of control of $12 million , net of a tax impact of $1 million . The gain upon change of control is recognized within other income (expense), net and the tax impact is recognized within income tax benefit (expense). Hartwell Innovation Campus Acquisition In July 2019, the Company acquired a life science campus in the suburban Boston submarket of Lexington, Massachusetts, for $228 million . The campus is comprised of four buildings.

Other Real Estate Acquisitions During the year ended December 31, 2019, the Company acquired one medical office building (“MOB”) in Kansas for $15 million , one MOB in Texas for $9 million , and one life science building in the Sorrento Mesa submarket of San Diego, California for $16 million . Development Activities The Company’s commitments related to development and redevelopment projects decreased by $17 million , to $344 million at June 30, 2020 , when compared to December 31, 2019 , primarily as a result of completed development and redevelopment projects, partially offset by increased commitments on existing projects and new projects started during the second quarter of 2020. As part of the development program with HCA Healthcare, Inc., during the three months ended June 30, 2020 , the Company commenced development of one MOB, which will be on-campus. Held for Sale At June 30, 2020 , 12 senior housing triple-net facilities, 6 MOBs, 1 undeveloped MOB land parcel, 33 SHOP facilities, and 2 facilities included in the Company’s other non-reportable segment were classified as held for sale, with an aggregate carrying value of $379 million , primarily comprised of real estate assets of $367 million (net of accumulated depreciation of $239 million ). Liabilities of assets held for sale was primarily comprised of mortgage debt of $28 million and other liabilities of $5 million at June 30, 2020 . At December 31, 2019 , 27 senior housing triple-net facilities (inclusive of 18 facilities sold to Brookdale under the 2019 MTCA - see Note 3), 28 SHOP facilities, and 2 MOBs were classified as held for sale, with an aggregate carrying value of $504 million , primarily comprised of real estate assets of $476 million (net of accumulated depreciation of $243 million ). Liabilities of assets held for sale were primarily comprised of mortgage debt of $32 million and other liabilities of $4 million at December 31, 2019 . 2020 Dispositions of Real Estate During the three months ended June 30, 2020 , the Company sold two SHOP assets for $ 28 million , resulting in total gain on sales of $2 million . Additionally, during the three months ended June 30, 2020 , one of the Company’s tenants exercised its option to acquire three MOBs in San Diego, California for $106 million . The Company completed the sale in June 2020 and recognized total gain on sales of $81 million . During the three months ended March 31, 2020, the Company sold 7 SHOP assets for $36 million and 18 senior housing triple-net assets for $385 million (representative of the 18 facilities sold to Brookdale under the 2019 MTCA - see Note 3), resulting in total gain on sales of $165 million . 2019 Dispositions of Real Estate During the three months ended June 30, 2019 , the Company sold one SHOP asset for $14 million , five MOBs for $15 million , and one life science asset for $7 million , resulting in total gain on sales of $11 million . During the six months ended June 30, 2019 , the Company sold 10 SHOP assets for $82 million , 2 senior housing triple-net assets for $26 million , 5 MOBs for $15 million , 1 life science asset for $7 million , and 1 undeveloped life science land parcel for $35 million , resulting in total gain on sales of $19 million . Impairments of Real Estate 2020 During the three months ended June 30, 2020 , the Company recognized an aggregate impairment charge of $19 million related to 12 SHOP assets, 2 senior housing triple-net assets, 1 MOB, and 1 undeveloped MOB land parcel that are classified as held for sale and wrote down their aggregate carrying value of $108 million to their aggregate fair value, less estimated costs to sell, of $89 million . During the six months ended June 30, 2020 , the Company recognized an aggregate impairment charge of $50 million related to 20 SHOP assets, 4 senior housing triple-net assets, 2 MOBs, and 1 undeveloped MOB land parcel as a result of being classified as held for sale and wrote down their aggregate carrying value of $231 million to their aggregate fair value, less estimated costs to sell, of $181 million . The fair value of the impaired assets was based on forecasted sales prices, which are considered to be Level 3 measurements within the fair value hierarchy. Forecasted sales prices were determined using a direct capitalization model and/or a market approach (comparable sales model), which rely on certain assumptions by management, including: (i) market capitalization rates, (ii) comparable market transactions, (iii) estimated prices per unit, (iv) negotiations with prospective buyers, and (v) forecasted cash flow streams (lease revenue rates, expense rates, growth rates, etc.). There are inherent uncertainties in making these assumptions. For the Company’s impairment calculations during and as of the six months ended June 30, 2020 , the Company’s fair value estimates primarily relied on a market approach and utilized prices per unit ranging from $35,000 to $238,000 , with a weighted average price of $90,000 . 2 019 During the three months ended June 30, 2019 , the Company recognized an aggregate impairment charge of $59 million related to 2 senior housing triple-net assets, 14 SHOP assets, and 1 MOB that were classified as held for sale and wrote down their aggregate carrying value of $164 million to their aggregate fair value, less estimated costs to sell, of $105 million . The fair value of the impaired assets was based on forecasted sales prices, which are considered to be Level 3 measurements within the fair value hierarchy. For the Company’s impairment calculations during the three months ended June 30, 2019, the Company estimated the fair value of each asset using either (i) market capitalization rates ranging from 4.97% to 6.64% , with a weighted average rate of 5.41% or (ii) prices per unit ranging from $52,000 to $90,000 , with a weighted average price of $62,000 . Additionally, during the three months ended June 30, 2019 , the Company recognized a $6 million casualty-related gain, net of a $0.3 million deferred tax expense, as a result of insurance proceeds received for property damage and other associated costs related to hurricanes in 2017. The gain is recorded in other income (expense), net. In addition to the impairments described above, during the six months ended June 30, 2019 , the Company determined the carrying value of two MOBs that were candidates for potential future sale were no longer recoverable due to the Company’s shortened intended hold period under the held-for-use impairment model. Accordingly, the Company wrote-down the carrying amount of these two assets to their respective fair value, which resulted in an aggregate impairment charge of $9 million . The fair value of the assets are considered to be Level 2 measurements within the fair value hierarchy.

At December 31, 2019 , the Company had $25 million remaining of commitments to fund $174 million of senior housing development and redevelopment projects. 2020 Loans Receivable Transactions For certain residents that qualify, CCRCs may offer to lend residents the necessary funds to satisfy the entrance fee requirements so that they are able to move into a community while still continuing the process of selling their previous home. The loans are due upon sale of the previous residence. Upon completing the CCRC Acquisition (see Note 3) in January 2020, the Company began consolidating 13 CCRCs, which held approximately $30 million of such notes receivable from various community residents at the time of acquisition. At June 30, 2020 , the Company held $27 million of such receivables. Loans Receivable Internal Ratings In connection with the Company’s quarterly review process or upon the occurrence of a significant event, loans receivable are reviewed and assigned an internal rating of Performing, Watch List, or Workout. Loans that are deemed Performing meet all present contractual obligations, and collection and timing of all amounts owed is reasonably assured. Watch List Loans are defined as loans that do not meet the definition of Performing or Workout. Workout Loans are defined as loans in which the Company has determined, based on current information and events, that: (i) it is probable it will be unable to collect all amounts due according to the contractual terms of the agreement, (ii) the borrower is delinquent on making payments under the contractual terms of the agreement, and (iii) the Company has commenced action or anticipates pursuing action in the near term to seek recovery of its investment.

The Company’s evaluation considers industry and economic conditions, individual and portfolio property performance, credit enhancements, liquidity, and other factors. The Company’s borrowers furnish property, portfolio, and guarantor/operator-level financial statements, among other information, on a monthly or quarterly basis, which the Company utilizes to calculate the debt service coverages used in its assessment of internal ratings, which is a primary credit quality indicator. Debt service coverage information is evaluated together with other property, portfolio, and operator performance information, including revenue, expense, net operating income, occupancy, rental rates, capital expenditures, and EBITDA (defined as earnings before interest, tax, and depreciation and amortization), along with other liquidity measures. In its assessment of credit losses for loans receivable and unfunded loan commitments, the Company utilizes past payment history of its borrowers, current economic conditions, and forecasted economic conditions through the maturity date of each loan to estimate a probability of default and a resulting loss for each loan receivable. Future economic conditions are based primarily on near-term economic forecasts from the Federal Reserve and reasonable assumptions for long-term economic trends. The following table summarizes the Company’s reserve for loan losses at June 30, 2020 (in thousands): June 30, 2020 Secured Mortgage Loans Mezzanine and Other Total Reserve for loan losses, December 31, 2019 $ — $ — $ — Cumulative-effect of adopting of ASU 2016-13 to beginning retained earnings 513 907 1,420 Provision for expected loan losses 6,138 6,557 12,695 Reserve for loan losses, June 30, 2020 $ 6,651 $ 7,464 $ 14,115 Additionally, at June 30, 2020 , a liability of $1 million related to expected credit losses for unfunded loan commitments was included in accounts payable, accrued liabilities, and other liabilities. Credit loss expenses and recoveries are recorded in impairments and loan loss reserves (recoveries), net. During the three and six months ended June 30, 2020 , net credit loss expenses were $5 million and $13 million , respectively. The change in the provision for expected loan losses during the three and six months ended June 30, 2020 is primarily due to additional funding under existing loans, new loans funded, and the current and anticipated economic impact of COVID-19.

The plaintiff in the class action suit demands compensatory damages (in an unspecified amount), costs and expenses (including attorneys’ fees and expert fees), and equitable, injunctive, or other relief as the Court deems just and proper. On November 28, 2017, the Court appointed Societe Generale Securities GmbH (SGSS Germany) and the City of Birmingham Retirement and Relief Systems (Birmingham) as Co-Lead Plaintiffs in the class action. The motion to dismiss was fully briefed on May 21, 2018 and oral arguments were held on October 23, 2018. Subsequently, on December 6, 2018, HCRMC and its officers were voluntarily dismissed from the class action lawsuit without prejudice to such claims being refiled. On November 22, 2019, the Court granted the motion to dismiss. On December 20, 2019, Co-Lead plaintiffs filed a motion to amend the Court's judgment. Defendants' opposition brief was filed on February 18, 2020, and Co-Lead Plaintiffs' reply brief was filed on April 2, 2020. On May 18, 2020, Defendants filed a motion seeking leave to file a sur-reply, on May 21, 2020, Co-Lead Plaintiffs filed an opposition brief, and on May 28, 2020, Defendants filed a reply in support of the motion. Both motions have been fully briefed and remain pending with the Court. The Company believes the suit to be without merit and intends to vigorously defend against it. Derivative Actions. On June 16, 2016 and July 5, 2016, purported stockholders of the Company filed two derivative actions, Subodh v. HCR ManorCare Inc., et al. , Case No. 30-2016-00858497-CU-PT-CXC and Stearns v. HCR ManorCare, Inc., et al. , Case No. 30-2016-00861646-CU-MC-CJC, in the Superior Court of California, County of Orange, against certain of the Company’s current and former directors and officers and HCRMC. The Company is named as a nominal defendant. As both derivative actions contained substantially the same allegations, they have been consolidated into a single action (the “California derivative action”). The consolidated action alleges that the defendants engaged in various acts of wrongdoing, including, among other things, breaching fiduciary duties by publicly making false or misleading statements of fact regarding HCRMC’s finances and prospects and failing to maintain adequate internal controls. On April 18, 2017, the Court approved the parties’ stipulation to stay the case pending disposition of the motion to dismiss the class action litigation. On April 10, 2017, a purported stockholder of the Company filed a derivative action, Weldon v. Martin et al. , Case No. 3:17-cv-755, in federal court in the Northern District of Ohio, Western Division, against certain of the Company’s current and former directors and officers and HCRMC. The Company is named as a nominal defendant. The Weldon complaint asserts similar claims to those asserted in the California derivative action. In addition, the complaint asserts a claim under Section 14(a) of the Exchange Act, alleging that the Company made false statements in its 2016 proxy statement by not disclosing that the Company’s performance issues in 2015 were the direct result of alleged billing fraud at HCRMC. On April 18, 2017, the Court re-assigned and transferred this action to the judge presiding over the related federal securities class action. On July 11, 2017, the Court approved a stipulation by the parties to stay the case pending disposition of the motion to dismiss the class action. On July 21, 2017, a purported stockholder of the Company filed another derivative action, Kelley v. HCR ManorCare, Inc., et al. , Case No. 8:17-cv-01259, in federal court in the Central District of California, against certain of the Company’s current and former directors and officers and HCRMC. The Company is named as a nominal defendant. The Kelley complaint asserts similar claims to those asserted in Weldon and in the California derivative action. Like Weldon , the Kelley complaint also additionally alleges that the Company made false statements in its 2016 proxy statement, and asserts a claim for a violation of Section 14(a) of the Exchange Act. On November 28, 2017, the federal court in the Central District of California granted Defendants’ motion to transfer the action to the Northern District of Ohio (i.e., the court where the class action and other federal derivative action are pending). The Court in the Northern District of Ohio is currently considering whether to consolidate the Weldon and Kelley actions, appointment of lead plaintiffs and counsel, and whether the stay in Weldon should continue as to either or both actions. The Company’s Board of Directors received letters dated August 17, 2016, April 19, 2017, and April 20, 2017 from private law firms acting on behalf of clients who are purported stockholders of the Company, each asserting allegations similar to those made in the California derivative action matters discussed above. Each letter demands that the Board of Directors take action to assert the Company’s rights. The Board of Directors completed its evaluation and rejected the demand letters in December of 2017. One of the law firms has more recently requested that the Board of Directors reconsider its determination after a ruling on the motion to dismiss in the class action litigation. The Company believes that the plaintiffs lack standing or the lawsuits and demands are without merit, but cannot predict the outcome of these proceedings or reasonably estimate any potential loss at this time. Accordingly, no loss contingency has been recorded for these matters as of June 30, 2020 , as the likelihood of loss is not considered probable or estimable. Credit Enhancement Guarantee As of June 30, 2020 , certain of the Company’s senior housing facilities served as collateral for $60 million of debt (maturing May 1, 2025) that is owed by a previous owner of the facilities. This indebtedness is guaranteed by the previous owner who has an investment grade credit rating. These senior housing facilities had a carrying value of $325 million as of June 30, 2020 . DownREIT LLCs In connection with the formation of certain DownREIT LLCs, members may contribute appreciated real estate to a DownREIT LLC in exchange for DownREIT units. These contributions are generally tax-deferred, so that the pre-contribution gain related to the property is not taxed to the member. However, if a contributed property is later sold by the DownREIT LLC, the unamortized pre-contribution gain that exists at the date of sale is specifically allocated and taxed to the contributing members. In many of the DownREITs, the Company has entered into indemnification agreements with those members who contributed appreciated property into the DownREIT LLC. Under these indemnification agreements, if any of the appreciated real estate contributed by the members is sold by the DownREIT LLC in a taxable transaction within a specified number of years, the Company will reimburse the affected members for the federal and state income taxes associated with the pre-contribution gain that is specially allocated to the affected member under the Code (“make-whole payments”). These make-whole payments include a tax gross-up provision. These indemnification agreements have expirations terms that range through 2039 on a total of 27

Equity [Abstract]
Equity	Equity At-The-Market Equity Offering Program In June 2015, the Company established an at-the-market equity offering program (“ATM Program”) to sell shares of its common stock from time to time through a consortium of banks acting as sales agents or directly to the banks acting as principals. In February 2020, the Company terminated its previous ATM Program (the “2019 ATM Program”) and established a new ATM Program (the “2020 ATM Program”) pursuant to which shares of common stock having an aggregate gross sales price of up to approximately $1.25 billion may be sold (i) by the Company through a consortium of banks acting as sales agents or directly to the banks acting as principals or (ii) by a consortium of banks acting as forward sellers on behalf of any forward purchasers pursuant to a forward sale agreement. The use of a forward sale agreement allows the Company to lock in a share price on the sale of shares at the time the forward sales agreement is effective, but defer receiving the proceeds from the sale of shares until a later date. ATM forward sale agreements generally have a one year term. At any time during the term, the Company may settle a forward sale by delivery of physical shares of common stock to the forward seller or, at the Company’s election, in cash or net shares. The forward sale price the Company expects to receive upon settlement of outstanding forward contracts will be the initial forward price established upon the effective date, subject to adjustments for: (i) accrued interest, (ii) the forward purchasers’ stock borrowing costs, and (iii) certain fixed price reductions during the term of the forward sale agreement. ATM Forward Contracts During the three months ended June 30, 2020 , the Company did not utilize the forward provisions under the 2020 ATM Program. During the six months ended June 30, 2020 , the Company utilized the forward provisions under the 2019 ATM Program to allow for the sale of up to an aggregate of 2.0 million shares of its common stock at an initial weighted average net price of $35.23 per share, after commissions. During the three and six months ended June 30, 2019 , the Company utilized the forward provisions under the 2019 ATM Program to allow for the sale of up to an aggregate of 10.1 million and 13.6 million shares of its common stock, respectively, at an initial weighted average net price of $31.26 and $31.24 per share, after commissions, respectively. During the three months ended March 31, 2020, the Company settled all 16.8 million shares previously outstanding under ATM forward contracts at a weighted average net price of $31.38 per share, after commissions, resulting in net proceeds of $528 million . No shares were settled during the three months ended June 30, 2020 and at June 30, 2020 , no shares remained outstanding under ATM forward contracts. During the three and six months ended June 30, 2019 , the Company settled 5.5 million shares at a weighted average net price of $30.91 per share, after commissions, resulting in net proceeds of $171 million . At June 30, 2020 , approximately $1.25 billion of the Company’s common stock remained available for sale under the 2020 ATM Program. ATM Direct Issuances During the three and six months ended June 30, 2020 , no shares of common stock were issued under the 2019 ATM Program or 2020 ATM Program. During the three and six months ended June 30, 2019 , the Company issued 5.9 million shares of common stock under the 2019 ATM Program at a weighted average net price of $31.84 per share, after commissions, resulting in net proceeds of $189 million . Forward Equity Offerings November 2019 Offering. In November 2019, the Company entered into a forward equity sales agreement (the "2019 forward equity sales agreement") to sell an aggregate of 15.6 million shares of its common stock (including shares sold through the exercise of underwriters’ options) at an initial net price of $34.46 per share, after underwriting discounts and commissions, which was subject to adjustments for: (i) accrued interest, (ii) the forward purchasers’ stock borrowing costs, and (iii) certain fixed price reductions during the term of the agreement. During the year ended December 31, 2019 , no shares were settled under the 2019 forward equity sales agreement. During the three months ended March 31, 2020 , the Company settled all 15.6 million shares under the 2019 forward equity sales agreement at a weighted average net price of $34.18 per share, resulting in net proceeds of $534 million (total net proceeds of $1.06 billion , when aggregated with the net proceeds from settling ATM forward contracts, as discussed above). Therefore, at June 30, 2020 , no shares remained outstanding under the 2019 forward equity sales agreement. December 2018 Offering. In December 2018, the Company entered into a forward equity sales agreement (the “2018 forward equity sales agreement”) to sell an aggregate of 15.3 million shares of its common stock (including shares sold through the exercise of underwriters’ options) at an initial net price of $28.60 per share, after underwriting discounts and commissions. The 2018 forward equity sales agreement had a one year term that expired on December 13, 2019 during which time the Company could settle the forward sales agreement by delivery of physical shares of common stock to the forward seller or, at the Company’s election, settle in cash or net shares. During the three and six months ended June 30, 2019 , the Company settled 1.5 million shares under the forward sales agreement at a net price of $28.11 per share, resulting in net proceeds of $42 million . During the year ended December 31, 2019 , the Company settled all 15.3 million shares under the 2018 forward equity sales agreement at a weighted average net price of $27.66 per share, resulting in net proceeds of $422 million . Therefore, at December 31, 2019 , no shares remained outstanding under the 2018 forward equity sales agreement.

Earnings Per Common Share

Earnings Per Share [Abstract]
Earnings Per Common Share	Earnings Per Common Share Basic income (loss) per common share (“EPS”) is computed based on the weighted average number of common shares outstanding. Diluted income (loss) per common share is computed based on the weighted average number of common shares outstanding plus the impact of forward equity sales agreements using the treasury stock method and common shares issuable from the assumed conversion of DownREIT units, stock options, certain performance restricted stock units, and unvested restricted stock units. Only those instruments having a dilutive impact on the Company’s basic income (loss) per share are included in diluted income (loss) per share during the periods presented. Restricted stock and certain performance restricted stock units are considered participating securities, because dividend payments are not forfeited even if the underlying award does not vest, and require use of the two-class method when computing basic and diluted earnings per share. Refer to Note 11 for a discussions of the sale of shares under and settlement of forward sales agreements during the periods presented. The Company considered the potential dilution resulting from the forward agreements to the calculation of earnings per share. At inception, the agreements do not have an effect on the computation of basic EPS as no shares are delivered until settlement. However, the Company uses the treasury stock method to calculate the dilution, if any, resulting from the forward sales agreements during the period of time prior to settlement. The aggregate effect on the Company’s diluted weighted-average common shares for the six months ended June 30, 2020 and 2019 , was 0.8 million and 1.3 million weighted-average incremental shares, respectively, from the forward equity sales agreements. The following table illustrates the computation of basic and diluted earnings per share (in thousands, except per share amounts): Three Months Ended Six Months Ended 2020 2019 2020 2019 Numerator Net income (loss) $ 55,049 $ (9,980 ) $ 337,589 $ 55,010 Noncontrolling interests' share in earnings (3,543 ) (3,617 ) (7,003 ) (7,137 ) Net income (loss) attributable to Healthpeak Properties, Inc. 51,506 (13,597 ) 330,586 47,873 Less: Participating securities' share in earnings (375 ) (394 ) (1,800 ) (837 ) Net income (loss) applicable to common shares $ 51,131 $ (13,991 ) $ 328,786 $ 47,036 Denominator Basic weighted average shares outstanding 538,262 478,739 522,427 478,260 Dilutive potential common shares - equity awards (1) 255 — 263 281 Dilutive potential common shares - forward equity agreements (2) — — 808 1,344 Diluted weighted average common shares 538,517 478,739 523,498 479,885 Earnings (loss) per common share: Basic $ 0.09 $ (0.03 ) $ 0.63 $ 0.10 Diluted $ 0.09 $ (0.03 ) $ 0.63 $ 0.10 _______________________________________ (1) For all periods presented, represents the dilutive impact of 1 million outstanding equity awards (restricted stock units and stock options).

For the three months ended June 30, 2020 , forward sales agreements had no dilutive impact as all agreements were settled prior to the start of the period. For the three months ended June 30, 2019 , diluted loss per share is calculated using the weighted average common shares outstanding as a result of the Company generating a net loss applicable to common shares for the period.

Segment Disclosures

Segment Reporting [Abstract]
Segment Disclosures	Segment Disclosures The Company evaluates its business and allocates resources based on its reportable business segments: (i) senior housing triple-net, (ii) SHOP, (iii) CCRC, (iv) life science, and (v) medical office. The Company has non-reportable segments that are comprised primarily of the Company’s hospital properties and debt investments. The accounting policies of the segments are the same as those in Note 2 to the Consolidated Financial Statements in the Company’s 2019 Annual Report on Form 10-K filed with the SEC, as updated by Note 2 herein. During the first quarter of 2020, primarily as a result of: (i) acquiring 100% ownership interest in 13 of 15 CCRCs previously held by a CCRC joint venture (see discussion of the 2019 MTCA with Brookdale in Note 3) and (ii) deconsolidating 19 SHOP assets into a new joint venture in December 2019, the Company's CODMs began reviewing operating results of CCRCs on a stand-alone basis and financial information for each respective segment inclusive of the Company’s share of unconsolidated joint ventures and exclusive of noncontrolling interests’ share on consolidated joint ventures. Therefore, during the first quarter of 2020, the Company began reporting CCRCs as a separate segment and began reporting segment measures inclusive of the Company’s share of unconsolidated joint ventures and exclusive of noncontrolling interests’ share of consolidated joint ventures. Accordingly, all prior period segment information has been recast to conform to the current period presentation. During the three and six months ended June 30, 2020 , two and nine senior housing triple-net facilities, respectively, were transferred to the Company’s SHOP segment as a result of terminating the triple-net leases and converting the assets to a RIDEA structure. During the three and six months ended June 30, 2019 , 21 and 39 senior housing triple-net facilities, respectively, were transferred to the Company’s SHOP segment as a result of terminating the triple-net leases and converting the assets to a RIDEA structure. When an asset is transferred from one segment to another, the results associated with that asset are included in the original segment until the date of transfer. Results generated after the transfer date are included in the new segment. The Company evaluates performance based on property Adjusted NOI. NOI is defined as real estate revenues (inclusive of rental and related revenues, resident fees and services, income from direct financing leases, and government grant income and exclusive of interest income), less property level operating expenses (which exclude transition costs); NOI excludes all other financial statement amounts included in net income (loss) . Adjusted NOI is calculated as NOI after eliminating the effects of straight-line rents, DFL non-cash interest, amortization of market lease intangibles, termination fees, actuarial reserves for insurance claims that have been incurred but not reported, and the impact of deferred community fee income and expense. NOI and Adjusted NOI include the Company’s share of income (loss) from unconsolidated joint ventures and exclude noncontrolling interests’ share of income (loss) from consolidated joint ventures. Management believes Adjusted NOI is an important supplemental measure because it provides relevant and useful information by reflecting only income and operating expense items that are incurred at the property level and presenting it on an unlevered basis. Non-segment assets consist of assets in the Company's other non-reportable segments and corporate non-segment assets. Corporate non-segment assets consist primarily of corporate assets, including cash and cash equivalents, restricted cash, accounts receivable, net, marketable equity securities, and real estate assets and liabilities held for sale. The following tables summarize information for the reportable segments (in thousands): For the three months ended June 30, 2020 : Senior Housing Triple-Net SHOP CCRC Life Science Medical Office Other Non-reportable Corporate Non-segment Total Total revenues $ 24,589 $ 155,293 $ 113,926 $ 138,496 $ 141,636 $ 14,500 $ — $ 588,440 Government grant income (1) — 2,209 11,871 — — — — 14,080 Less: Interest income — — — — — (4,230 ) — (4,230 ) Healthpeak's share of unconsolidated joint venture total revenues — 24,684 4,781 — 691 — — 30,156 Healthpeak's share of unconsolidated joint venture government grant income — 270 534 — — — — 804 Noncontrolling interests' share of consolidated joint venture total revenues — (504 ) — (57 ) (8,347 ) — — (8,908 ) Operating expenses (526 ) (137,507 ) (94,248 ) (34,205 ) (49,350 ) (5 ) — (315,841 ) Healthpeak's share of unconsolidated joint venture operating expenses — (18,686 ) (4,826 ) — (275 ) (1 ) — (23,788 ) Noncontrolling interests' share of consolidated joint venture operating expenses — 411 — 18 2,507 — — 2,936 Adjustments to NOI (2) 41 118 18 (2,779 ) (951 ) 485 — (3,068 ) Adjusted NOI 24,104 26,288 32,056 101,473 85,911 10,749 — 280,581 Plus: Adjustments to NOI (2) (41 ) (118 ) (18 ) 2,779 951 (485 ) — 3,068 Interest income — — — — — 4,230 — 4,230 Interest expense (72 ) (2,837 ) (1,969 ) (60 ) (100 ) — (52,512 ) (57,550 ) Depreciation and amortization (7,175 ) (31,621 ) (31,426 ) (52,356 ) (54,572 ) (1,338 ) — (178,488 ) General and administrative — — — — — — (23,720 ) (23,720 ) Transaction costs — — — — — — (627 ) (627 ) Impairments and loan loss reserves (recoveries), net (1,007 ) (16,158 ) — — (2,119 ) (4,766 ) — (24,050 ) Gain (loss) on sales of real estate, net — 1,579 — — 81,284 — — 82,863 Loss on debt extinguishments — — — — — — (25,824 ) (25,824 ) Other income (expense), net — 2,209 14,142 — — — 3,235 19,586 Income tax benefit (expense) — — — — — — 7,346 7,346 Less: Government grant income — (2,209 ) (11,871 ) — — — — (14,080 ) Less: Healthpeak's share of unconsolidated joint venture NOI — (6,268 ) (489 ) — (416 ) 1 — (7,172 ) Plus: Noncontrolling interests' share of consolidated joint venture NOI — 93 — 39 5,840 — — 5,972 Equity income (loss) from unconsolidated joint ventures — (17,779 ) 401 — 210 82 — (17,086 ) Net income (loss) $ 15,809 $ (46,821 ) $ 826 $ 51,875 $ 116,989 $ 8,473 $ (92,102 ) $ 55,049 _______________________________________ (1) Represents government grant income received under the CARES Act, which is recorded in other income (expense), net in the consolidated statements of operations.

Variable Interest Entities

Variable Interest Entities	6 Months Ended
	Jun. 30, 2020
Variable Interest Entities [Abstract]
Variable Interest Entities	Variable Interest Entities Unconsolidated Variable Interest Entities At June 30, 2020 , the Company had investments in: (i) two properties leased to a VIE tenant, (ii) five unconsolidated VIE joint ventures, (iii) marketable debt securities of one VIE, and (iv) one loan to a VIE borrower. The Company determined it is not the primary beneficiary of and therefore does not consolidate these VIEs because it does not have the ability to control the activities that most significantly impact their economic performance. Except for the Company’s equity interest in the unconsolidated joint ventures (CCRC OpCo, development investments, Waldwick JV, and the LLC investment discussed below), it has no formal involvement in these VIEs beyond its investments. VIE Tenant. The Company leases two properties to one tenant that has been identified as a VIE (“VIE tenant”). The VIE tenant is a “thinly capitalized” entity that relies on the operating cash flows generated from the senior housing facilities to pay operating expenses, including the rent obligations under its leases. CCRC OpCo. The Company holds a 49% ownership interest in CCRC OpCo, a joint venture entity formed in August 2014 that operates senior housing properties in a RIDEA structure and has been identified as a VIE. The equity members of CCRC OpCo “lack power” because they share certain operating rights with Brookdale, as manager of the CCRCs. The assets of CCRC OpCo primarily consist of the CCRCs that it owns and leases, resident fees receivable, notes receivable, and cash and cash equivalents; its obligations primarily consist of operating lease obligations to CCRC PropCo, debt service payments, capital expenditures, accounts payable, and expense accruals. Assets generated by the operations of CCRC OpCo (primarily rents from CCRC residents) may only be used to settle its contractual obligations (primarily from debt service payments, capital expenditures, and rental costs and operating expenses incurred to manage such facilities). Refer to Note 3 for additional discussion related to transactions impacting CCRC OpCo. Waldwick Development JV. The Company holds an 85% ownership interest in a joint venture (the “Waldwick JV”), which has been identified as a VIE as power is shared with a member that does not have a substantive equity investment at risk. The assets of the joint venture primarily consist of a senior housing facility that it owns and cash and cash equivalents; its obligations primarily consist of capital expenditures, accounts payable, and expense accruals. Any assets generated by the joint venture may only be used to settle its contractual obligations (primarily capital expenditures and rental costs and operating expenses incurred to manage such facilities). LLC Investment. The Company holds a limited partner ownership interest in an unconsolidated LLC that has been identified as a VIE. The Company’s involvement in the entity is limited to its equity investment as a limited partner and it does not have any substantive participating rights or kick-out rights over the general partner. The assets and liabilities of the entity primarily consist of those associated with its senior housing real estate and development activities. Any assets generated by the entity may only be used to settle its contractual obligations (primarily development expenses and debt service payments). Development Investments. The Company holds investments (consisting of mezzanine debt and/or preferred equity) in two senior housing development joint ventures. The joint ventures are also capitalized by senior loans from a third party and equity from the third party managing-member, but are considered to be “thinly capitalized” as there is insufficient equity investment at risk. Debt Securities Investment. The Company holds commercial mortgage-backed securities (“CMBS”) issued by Federal Home Loan Mortgage Corporation (commonly referred to as Freddie MAC) through a special purpose entity that has been identified as a VIE because it is “thinly capitalized.” The CMBS issued by the VIE are backed by mortgage debt obligations on real estate assets. Seller Financing Loan. The Company provided seller financing of $10 million related to its sale of seven senior housing triple-net facilities. The financing was provided in the form of a secured five –year mezzanine loan to a “thinly capitalized” borrower created to acquire the facilities. The classification of the related assets and liabilities and the maximum loss exposure as a result of the Company’s involvement with these VIEs at June 30, 2020 was as follows (in thousands): VIE Type Asset/Liability Type Maximum Loss Exposure and Carrying Amount (1) VIE tenant - operating leases (2) Lease intangibles, net and straight-line rent receivables $ 1,811 Unconsolidated development joint ventures Loans receivable, net and Investments in unconsolidated joint ventures 27,356 Loan - seller financing Loans receivable, net 6,221 CMBS and LLC investment Marketable debt and LLC investment 35,151 _______________________________________ (1) The Company’s maximum loss exposure represents the aggregate carrying amount of such investments (including accrued interest). (2) The Company’s maximum loss exposure may be mitigated by re-leasing the underlying properties to new tenants upon an event of default. As of June 30, 2020 , the Company had not provided, and is not required to provide, financial support through a liquidity arrangement or otherwise, to its unconsolidated VIEs, including under circumstances in which it could be exposed to further losses (e.g., cash shortfalls). See Notes 3, 4, 5, 6, and 7 for additional descriptions of the nature, purpose, and operating activities of the Company’s unconsolidated VIEs and interests therein. Consolidated Variable Interest Entities The Company’s consolidated total assets and total liabilities at June 30, 2020 and December 31, 2019 include certain assets of VIEs that can only be used to settle the liabilities of the related VIE. The VIE creditors do not have recourse to the Company. Total assets and total liabilities include VIE assets and liabilities as follows (in thousands): June 30, 2020 December 31, 2019 Assets Buildings and improvements $ 2,992,626 $ 3,236,105 Development costs and construction in progress 96,090 67,285 Land 447,759 526,576 Accumulated depreciation and amortization (623,212 ) (568,574 ) Net real estate 2,913,263 3,261,392 Accounts receivable, net 9,937 11,986 Cash and cash equivalents 41,590 47,027 Restricted cash 14,168 13,596 Intangible assets, net 143,965 206,840 Right-of-use asset, net 91,834 92,664 Other assets, net 57,030 52,124 Total assets $ 3,271,787 $ 3,685,629 Liabilities Mortgage debt 217,310 218,767 Intangible liabilities, net 18,289 39,545 Lease liability 91,332 90,875 Accounts payable, accrued liabilities, and other liabilities 108,103 122,832 Deferred revenue 91,113 96,985 Total liabilities $ 526,147 $ 569,004 Ventures V, LLC . The Company holds a 51% ownership interest in and is the managing member of a joint venture entity formed in October 2015 that owns and leases MOBs (“Ventures V”). The Company classifies Ventures V as a VIE due to the non-managing member lacking substantive participation rights in the management of Ventures V or kick-out rights over the managing member. The Company consolidates Ventures V as the primary beneficiary because it has the ability to control the activities that most significantly impact the VIE’s economic performance. The assets of Ventures V primarily consist of leased properties (net real estate), rents receivable, and cash and cash equivalents; its obligations primarily consist of capital expenditures for the properties. Assets generated by Ventures V may only be used to settle its contractual obligations (primarily from capital expenditures). Watertown JV . The Company holds a 95% ownership interest in and is the managing member of joint venture entities formed in November 2017 that own and operate a senior housing property in a RIDEA structure (“Watertown JV”). Watertown PropCo is a VIE as the Company and the non-managing member share in control of the entity, but substantially all of the entity's activities are performed on behalf of the Company. Watertown OpCo is a VIE as the non-managing member, through its equity interest, lacks substantive participation rights in the management of Watertown OpCo or kick-out rights over the managing member. The Company consolidates Watertown PropCo and Watertown OpCo as the primary beneficiary because it has the ability to control the activities that most significantly impact these VIEs’ economic performance. The assets of Watertown PropCo primarily consist of a leased property (net real estate), rents receivable, and cash and cash equivalents; its obligations primarily consist of notes payable to a non-VIE consolidated subsidiary of the Company. The assets of Watertown OpCo primarily consist of leasehold interests in a senior housing facility (operating lease), resident fees receivable, and cash and cash equivalents; its obligations primarily consist of lease payments to Watertown PropCo and operating expenses of its senior housing facilities (accounts payable and accrued expenses). Assets generated by the senior housing operations (primarily from senior housing resident rents) of the Watertown structure may only be used to settle its contractual obligations (primarily from the rental costs, operating expenses incurred to manage such facilities, and debt costs). Life Science JVs . The Company holds a 99% ownership interest in multiple joint venture entities that own and lease life science assets (the “Life Science JVs”). The Life Science JVs are VIEs as the members share in control of the entities, but substantially all of the activities are performed on behalf of the Company. The Company consolidates the Life Science JVs as the primary beneficiary because it has the ability to control the activities that most significantly impact these VIEs’ economic performance. The assets of the Life Science JVs primarily consist of leased properties (net real estate), rents receivable, and cash and cash equivalents; their obligations primarily consist of debt service payments and capital expenditures for the properties. Assets generated by the Life Science JVs may only be used to settle their contractual obligations (primarily from capital expenditures). MSREI MOB JV. The Company holds a 51% ownership interest in, and is the managing member of, a joint venture entity formed in August 2018 that owns and leases MOBs (the “MSREI JV”). The MSREI JV is a VIE due to the non-managing member lacking substantive participation rights in the management of the joint venture or kick-out rights over the managing member. The Company consolidates the MSREI JV as the primary beneficiary because it has the ability to control the activities that most significantly impact the VIE’s economic performance. The assets of the MSREI JV primarily consist of leased properties (net real estate), rents receivable, and cash and cash equivalents; its obligations primarily consist of capital expenditures for the properties. Assets generated by the MSREI JV may only be used to settle its contractual obligations (primarily from capital expenditures). Consolidated Lessees. The Company leases two senior housing properties to a lessee entity under a cash flow lease through which the Company receives monthly rent equal to the residual cash flows of the property. The lessee entity is classified as a VIE as it is a "thinly capitalized" entity. The Company consolidates the lessee entity as it has the ability to control the activities that most significantly impact the economic performance of the lessee entity. The lessee entity’s assets primarily consist of leasehold interests in a senior housing facility (operating leases), resident fees receivable, and cash and cash equivalents; its obligations primarily consist of lease payments to the Company and operating expenses of the senior housing facility (accounts payable and accrued expenses). Assets generated by the senior housing operations (primarily from senior housing resident rents) may only be used to settle its contractual obligations (primarily from the rental costs, operating expenses incurred to manage such facilities, and debt costs). DownREITs . The Company holds a controlling ownership interest in and is the managing member of seven limited liability companies (“DownREITs”). The Company classifies the DownREITs as VIEs due to the non-managing members lacking substantive participation rights in the management of the DownREITs or kick-out rights over the managing member. The Company consolidates the DownREITs as the primary beneficiary because it has the ability to control the activities that most significantly impact these VIEs’ economic performance. The assets of the DownREITs primarily consist of leased properties (net real estate), rents receivable, and cash and cash equivalents; their obligations primarily consist of debt service payments and capital expenditures for the properties. Assets generated by the DownREITs (primarily from resident rents) may only be used to settle their contractual obligations (primarily from debt service and capital expenditures). Other Consolidated Real Estate Partnerships. The Company holds a controlling ownership interest in and is the general partner (or managing member) of multiple partnerships that own and lease real estate assets (the “Partnerships”). The Company classifies the Partnerships as VIEs due to the limited partners (non-managing members) lacking substantive participation rights in the management of the Partnerships or kick-out rights over the general partner (managing member). The Company consolidates the Partnerships as the primary beneficiary because it has the ability to control the activities that most significantly impact these VIEs’ economic performance. The assets of the Partnerships primarily consist of leased properties (net real estate), rents receivable, and cash and cash equivalents; their obligations primarily consist of debt service payments and capital expenditures for the properties. Assets generated by the Partnerships (primarily from resident rents) may only be used to settle their contractual obligations (primarily from debt service and capital expenditures). Other consolidated VIEs. The Company made a loan to an entity that entered into a tax credit structure (“Tax Credit Subsidiary”) and a loan to an entity that made an investment in a development joint venture (“Development JV”) both of which are considered VIEs. The Company consolidates the Tax Credit Subsidiary and Development JV as the primary beneficiary because it has the ability to control the activities that most significantly impact the VIEs’ economic performance. The assets and liabilities of the Tax Credit Subsidiary and Development JV substantially consist of a development in progress, notes receivable, prepaid expenses, notes payable, and accounts payable and accrued liabilities generated from their operating activities. Any assets generated by the operating activities of the Tax Credit Subsidiary and Development JV may only be used to settle their contractual obligations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The following table summarizes the Company’s outstanding swap contracts as of June 30, 2020 (dollars in thousands): Date Entered Maturity Date Hedge Designation Notional Pay Rate Receive Rate Fair Value (1) Interest rate: July 2005 (2) July 2020 Cash Flow $ 41,305 3.82% BMA Swap Index $ (64 ) ______________________________________ (1) Derivative liabilities are recorded in accounts payable, accrued liabilities, and other liabilities in the consolidated balance sheets. (2) Represents three interest-rate swap contracts, which hedge fluctuations in interest payments on variable-rate secured debt due to overall changes in hedged cash flows. The Company uses derivative instruments to mitigate the effects of interest rate fluctuations on specific forecasted transactions as well as recognized financial obligations or assets. Utilizing derivative instruments allows the Company to manage the risk of fluctuations in interest rates related to the potential impact these changes could have on future earnings and forecasted cash flows. The Company does not use derivative instruments for speculative or trading purposes. Assuming a one percentage point shift in the underlying interest rate curve, the estimated change in fair value of each of the underlying derivative instruments would not exceed $1 million . In August 2020, the Company replaced the swap contracts in the table above with three new interest-rate swap contracts totaling $41 million of notional, which mature in August 2025 and are designated as an effective cash flow hedge.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Management is required to make estimates and assumptions in the preparation of financial statements in conformity with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from management’s estimates. The consolidated financial statements include the accounts of Healthpeak Properties, Inc., its wholly-owned subsidiaries, joint ventures (“JVs”), and variable interest entities (“VIEs”) that it controls through voting rights or other means. Intercompany transactions and balances have been eliminated upon consolidation. All adjustments (consisting of normal recurring adjustments) necessary to present fairly the Company’s financial position, results of operations, and cash flows have been included. Operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020 . The accompanying unaudited interim financial information should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2019 included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”).
Government Grant Income	Government Grant Income On March 27, 2020, the federal government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) to provide financial aid to individuals, businesses, and state and local governments. During the three and six months ended June 30, 2020 , the Company received government grants under the CARES Act of $15 million to primarily cover lost Medicare revenue during the COVID-19 pandemic. Grant income is recognized when there is reasonable assurance that the grant will be received and the Company will comply with any conditions attached to the grant. Additionally, grants are recognized over the periods in which the Company recognizes the lost income the grants are intended to defray. As of June 30, 2020 , the amount of qualifying expenditures and lost revenues exceeded amounts received under the CARES Act and the Company had complied with all grant conditions. Accordingly, during the three months ended June 30, 2020 , the Company recognized $14 million of grants in other income (expense), net and $1 million of grants in equity income (loss) from unconsolidated joint ventures in the consolidated statements of operations.
Segment Reporting	Segment Reporting The Company’s reportable segments, based on how it evaluates its business and allocates resources, are as follows: (i) senior housing triple-net, (ii) SHOP, (iii) CCRC, (iv) life science, and (v) medical office. In January 2020, primarily as a result of: (i) consolidating 13 of 15 CCRCs previously held by a CCRC joint venture (see discussion of the Brookdale 2019 Master Transaction and Cooperation Agreement in Note 3) and (ii) deconsolidating 19 SHOP assets into a new joint venture in December 2019, the Company's chief operating decision makers (“CODMs”) began reviewing operating results of CCRCs on a stand-alone basis and financial information for each respective segment inclusive of the Company’s share of unconsolidated joint ventures and exclusive of noncontrolling interests’ share of consolidated joint ventures. Therefore, during the first quarter of 2020, the Company began reporting CCRCs as a separate segment and segment measures inclusive of the Company’s share of unconsolidated joint ventures and exclusive of noncontrolling interests’ share of consolidated joint ventures. Accordingly, all prior period segment information has been recast to conform to the current period presentation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted Leases. In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 (codified under Accounting Standards Codification (“ASC”) 842, Leases ) amends the previous accounting for leases to: (i) require lessees to put most leases on their balance sheets (not required for short-term leases with lease terms of 12 months or less), but continue recognizing expenses on their income statements in a manner similar to requirements under prior accounting guidance, (ii) eliminate real estate specific lease provisions, and (iii) modify the classification criteria and accounting for sales-type leases for lessors. Additionally, ASU 2016-02 provides a practical expedient, which the Company elected, 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) lease classification related to expired or existing lease arrangements, or (iii) whether costs incurred on expired or existing leases qualify as initial direct costs. As a result of adopting ASU 2016-02 on January 1, 2019 using the modified retrospective transition approach, the Company recognized a cumulative-effect adjustment to equity of $1 million as of January 1, 2019. Under ASU 2016-02, the Company began capitalizing fewer costs related to the drafting and negotiation of its lease agreements. Additionally, the Company began recognizing all of its significant operating leases for which it is the lessee, including corporate office leases, equipment leases, and ground leases, on its consolidated balance sheets as a lease liability and corresponding right-of-use asset. As such, the Company recognized a lease liability of $153 million and right-of-use asset of $166 million on January 1, 2019. The aggregate lease liability was calculated as the present value of minimum lease payments, discounted using a rate that approximated the Company’s secured incremental borrowing rate at the time of adoption, adjusted for the noncancelable term of each lease. The right-of-use asset was calculated as the aggregate lease liability, adjusted for the existing accrued straight-line rent liability balance of $20 million and net unamortized above/below market ground lease intangible assets of $33 million . Other. E ffective January 1, 2019, the Company adopted ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”). The amendments in ASU 2017-12 expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. For cash flow and net investment hedges existing at the date of adoption, the Company adopted the amendments in ASU 2017-12 using the modified retrospective approach. For amendments impacting presentation and disclosure, the Company adopted ASU 2017-12 using a prospective approach. The adoption of ASU 2017-12 did not have a material impact to the Company’s consolidated financial position, results of operations, cash flows, or disclosures. Credit Losses. In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 is intended to improve financial reporting by requiring timelier recognition of credit losses on loans and other financial instruments held by financial institutions and other organizations. The amendments in ASU 2016-13 eliminate the “probable” initial threshold for recognition of credit losses in previous accounting guidance and, instead, reflect an entity’s current estimate of all expected credit losses over the life of the financial instrument. Historically, when credit losses were measured under previous accounting guidance, an entity generally only considered past events and current conditions in measuring the incurred loss. The amendments in ASU 2016-13 broaden the information that an entity must consider in developing its expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss. As a result of adopting ASU 2016-13 on January 1, 2020 using the modified retrospective transition approach, the Company recognized a cumulative-effect adjustment to equity of $2 million as of January 1, 2020. Under ASU 2016-13, the Company began using a loss model that relies on future expected credit losses, rather than incurred losses, as was required under historical GAAP. Under the new model, the Company is required to recognize future credit losses expected to be incurred over the life of its financing receivables, including loans receivable, direct financing leases (“DFLs”), and certain accounts receivable, at inception of those instruments. The model emphasizes historical experience and future market expectations to determine a loss to be recognized at inception. However, the model continues to be applied on an individual basis and rely on counter-party specific information to ensure the most accurate estimate is recognized. The Company will reassess its reserves on financing receivables at each balance sheet date to determine if an adjustment to the previous reserve is necessary. Accounting for Lease Concessions Related to COVID-19. In April 2020, the FASB staff issued a question-and-answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of COVID-19. Under ASC 842, the Company would have to determine, on a lease-by-lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A allows the Company, if certain criteria have been met, to bypass the lease-by-lease analysis, and instead elect to either apply the lease modification accounting framework or not, with such election applied consistently to leases with similar characteristics and similar circumstances. During the six months ended June 30, 2020 , the Company provided rent deferrals (to be repaid before the end of 2020) to certain tenants in its life science and medical office segments that were impacted by COVID-19 (discussed in further detail in Note 5). As it relates to these deferrals, the Company elected to not assess them on a lease-by-lease basis and to continue recognizing rent revenue on a straight-line basis. While the Company’s election for rent deferrals will be applied consistently to future deferrals of a similar nature, if the Company grants future lease concessions of a different type (such as rent abatements), it will make an election related to those concessions at that time.
