BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Business Overview and Organization Omega Healthcare Investors, Inc. (“Parent”) is a Maryland corporation that, together with its consolidated subsidiaries (collectively, “Omega,” the “Company,” “we,” “our,” or “us”) invests in healthcare-related real estate properties located in the United States (“U.S.”) and the United Kingdom (“U.K.”). Our core business is to provide financing and capital to the long-term healthcare industry with a particular focus on skilled nursing facilities (“SNFs”), assisted living facilities (“ALFs”), and to a lesser extent, independent living facilities (“ILFs”), rehabilitation and acute care facilities (“specialty facilities”) and medical office buildings. Our core portfolio consists of long-term “triple net” leases and real estate loans with healthcare operating companies and affiliates (collectively, our “operators”). In addition to our core investments, we make loans to operators and/or their principals. From time to time, we also acquire equity interests in joint ventures or entities that support the long-term healthcare industry and our operators. Omega has elected to be taxed as a real estate investment trust (“REIT”) for federal income tax purposes and is structured as an umbrella partnership REIT (“UPREIT”) under which all of Omega’s assets are owned directly or indirectly by, and all of Omega’s operations are conducted directly or indirectly through, its operating partnership subsidiary, OHI Healthcare Properties Limited Partnership (collectively with its subsidiaries, “Omega OP”). Omega has exclusive control over Omega OP’s day-to-day management pursuant to the partnership agreement governing Omega OP. As of June 30, 2023, Parent owned approximately 97% of the issued and outstanding units of partnership interest in Omega OP (“Omega OP Units”), and other investors owned approximately 3% of the outstanding Omega OP Units. Basis of Presentation and Principles of Consolidation The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all the information and notes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. In our opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The results of operations for the interim periods reported herein are not necessarily indicative of results to be expected for the full year. These unaudited consolidated financial statements should be read in conjunction with the financial statements and the footnotes thereto included in our Annual Report on Form 10-K Omega’s consolidated financial statements include the accounts of (i) Parent, (ii) all direct and indirect wholly owned subsidiaries of Omega, including Omega OP, (iii) other entities in which Omega or Omega OP has a majority voting interest and control and (iv) variable interest entities (“VIEs”) of which Omega is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation, and Omega’s net earnings are reduced by the portion of net earnings attributable to noncontrolling interests. Segments We conduct our operations and report financial results as one business segment. The presentation of financial results as one reportable segment is consistent with the way we operate our business and is consistent with the manner in which our Chief Operating Decision Maker (CODM), our Chief Executive Officer, evaluates performance and makes resource and operating decisions for the business. Reclassification Certain line items on our Consolidated Statements of Operations and Consolidated Statements of Cash Flows have been reclassified to conform to the current period presentation. Risks and Uncertainties including COVID-19 The Company is subject to certain risks and uncertainties affecting the healthcare industry, including those that arose from the novel coronavirus (“COVID-19”) global pandemic, which disproportionately impacted the senior care sector, as well as those stemming from healthcare legislation and changing regulation by federal, state and local governments. Additionally, we are subject to risks and uncertainties as a result of changes affecting operators of nursing home facilities due to the actions of governmental agencies and insurers to limit the rising cost of healthcare services. Recent Accounting Pronouncements ASU – 2020-04, Financial Instruments – Reference Rate Reform (Topic 848) On March 12, 2020, the issued 2020-04, which contains optional practical expedients for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting for contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”). The guidance may be elected over time until December 31, 2022, as reference rate reform activities occur. The Company had several derivative instruments that referenced LIBOR which were terminated during the second quarter of 2023 (see Note 16 – Derivatives and Hedging). The Company also had a $1.45 billion senior unsecured multicurrency revolving credit facility and a $50.0 million senior unsecured term loan facility (see Note 15 – Borrowing Activities and Arrangements) that referenced LIBOR.

ASSETS HELD FOR SALE, DISPOSITIONS AND IMPAIRMENTS [Abstract]
ASSETS HELD FOR SALE, DISPOSITIONS AND IMPAIRMENTS	NOTE 3 – ASSETS HELD FOR SALE, DISPOSITIONS AND IMPAIRMENTS Periodically we sell facilities to reduce our exposure to certain operators, geographies and non-strategic assets or due to the exercise of a tenant purchase option. The following is a summary of our assets held for sale: ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2023 2022 Number of facilities held for sale ​ 1 ​ ​ 2 Amount of assets held for sale (in thousands) $ 1,400 ​ $ 9,456 ​ Asset Sales During the three and six months ended June 30, 2023, we sold ten facilities (nine SNFs and one ILF) and 12 facilities (ten SNFs, one ILF and one medical office building) subject to operating leases, for approximately $44.7 million and $62.3 million in net cash proceeds, respectively. As a result of these sales, we recognized net gains of approximately $12.2 million and $25.9 million, respectively. The proceeds for the three and six months ended June 30, 2023 primarily relate to the sale of five facilities in the second quarter of 2023 that were previously leased to Guardian Healthcare (“Guardian”) and were included in assets held for sale as of March 31, 2023. The net cash proceeds from the sale were $23.8 million, and we did not recognize any gain or loss on the sale because we had already impaired the facilities down to the estimated fair value less costs to sell during the first quarter of 2023. Additionally, we sold one facility, also previously leased to Guardian, for a sales price of $12.0 million, which was fully financed by Omega through a $12.0 million first lien mortgage on the facility. The one facility sale and related seller financing did not meet the contract criteria to be recognized under ASC 610-20. During the three months ended June 30, 2023, we received interest of $0.2 million related to the seller financing, which was deferred and recorded as a contract liability within accrued expenses and other liabilities on our Consolidated Balance Sheets. During the three and six months ended June 30, 2022, we sold 13 and 40 facilities, subject to operating leases, for approximately $54.3 million and $386.9 million in net cash proceeds, respectively. As a result of these sales, we recognized net gains of approximately $25.2 million and $138.8 million during the three and six months ended June 30, 2022, respectively. Our 2022 sales were primarily driven by restructuring transactions and negotiations related to our lease agreements with Gulf Coast Health Care LLC (together with certain affiliates “Gulf Coast”) and Guardian. In the first quarter of 2022, we sold 22 facilities that were previously leased and operated by Gulf Coast. The net cash proceeds from the sale, including previously accrued for related costs, were $304.0 million, and we recognized a net gain of $113.5 million. During the first and second quarter of 2022, we sold nine total facilities that were leased to Guardian for $39.5 million in net proceeds, which resulted in a net gain of $13.7 million. In December 2022, in connection with restructuring negotiations with LaVie Care Centers, LLC (“LaVie,” f/k/a Consulate Health Care), we sold 11 facilities previously leased to LaVie to a third party for a sales price of $129.8 million. Omega provided $104.8 million in senior seller financing, collateralized by first lien mortgages on the 11 facilities, to fund a portion of the purchase price. The 11-facility sale does not meet the contract criteria to be recognized under ASC 610-20. During the three and six months ended June 30, 2023, we received interest of $2.1 million and $4.2 million, respectively, related to the $104.8 million in senior seller financing, which was deferred and recorded as a contract liability within accrued expenses and other liabilities on our Consolidated Balance Sheets. Real Estate Impairments During the three and six months ended June 30, 2023, we recorded impairments on four and six facilities of approximately $21.1 million and $60.1 million, respectively. Of the $60.1 million, $57.5 million related to four held-for-use facilities (of which $48.0 million relates to three facilities that were closed during the year) for which the carrying value exceeded the fair value and $2.6 million related to two facilities that were classified as held for sale for which the carrying value exceeded the estimated fair value less costs to sell. During the three and six months ended June 30, 2022, we recorded impairments on four and six facilities of approximately $7.7 million and $11.2 million, respectively. Of the $11.2 million, $3.5 million related to two facilities that were classified as held for sale for which the carrying values exceeded the estimated fair values less costs to sell, and $7.7 million related to four held-for-use facilities for which the carrying value exceeded the fair value. To estimate the fair value of the facilities for the impairments noted above, we utilized a market approach that considered binding sale agreements (a Level 1 input) or non-binding offers from unrelated third parties and/or broker quotes (a Level 3 input).

CONTRACTUAL RECEIVABLES AND OTHER RECEIVABLES AND LEASE INDUCEMENTS [Abstract]
CONTRACTUAL RECEIVABLES AND OTHER RECEIVABLES AND LEASE INDUCEMENTS	NOTE 4 – CONTRACTUAL RECEIVABLES AND OTHER RECEIVABLES AND LEASE INDUCEMENTS Contractual receivables relate to the amounts currently owed to us under the terms of our lease and loan agreements. Effective yield interest receivables relate to the difference between the interest income recognized on an effective yield basis over the term of the loan agreement and the interest currently due to us according to the contractual agreement. Straight-line rent receivables relate to the difference between the rental revenue recognized on a straight-line basis and the amounts currently due to us according to the contractual agreement. Lease inducements result from value provided by us to the lessee, at the inception, modification or renewal of the lease, and are amortized as a reduction of rental income over the non-cancellable lease term. A summary of our net receivables and lease inducements by type is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ ​ 2023 2022 ​ ​ (in thousands) ​ Contractual receivables – net ​ $ 8,837 ​ $ 8,228 ​ ​ ​ ​ ​ ​ ​ ​ ​ Effective yield interest receivables ​ $ 4,603 ​ $ 5,696 ​ Straight-line rent receivables ​ 190,360 ​ 166,061 ​ Lease inducements ​ 5,687 ​ 6,041 ​ Other receivables and lease inducements ​ $ 200,650 ​ $ 177,798 ​ ​ Cash Basis Operators and Straight-Line Receivable Write-Offs We review our collectibility assumptions related to our operator leases on an ongoing basis. During the three and six months ended June 30, 2023, we placed two new operators, which Omega has not previously had relationships with prior to the second quarter of 2023, on a cash basis of revenue recognition as collection of substantially all contractual lease payments due from them was not deemed probable. The new lease agreements with each of these operators were executed in the second quarter of 2023 as part of transitions of facilities from other operators, and we placed them on a cash basis concurrent with the respective lease commencement dates, so there were no straight-line rent write-offs associated with moving these operators to a cash basis. During the three and six months ended June 30, 2022, we placed two and four operators, respectively, on a cash basis of revenue recognition as collection of substantially all contractual lease payments due from such operators was not deemed probable. In connection with moving these operators to a cash basis, we recognized $10.4 million in total straight-line accounts receivable write-offs through rental income during the three and six months ended June 30, 2022. During the six months ended June 30, 2023, we transitioned the portfolios of four cash basis operators with an aggregate of 48 facilities, including 14 facilities related to the operator referred to as the “1.2% Operator” in our Annual Report on Form 10-K Form 10-K During the six months ended June 30, 2023 and 2022, we also wrote-off $0.9 million and $3.2 million, respectively, of straight-line rent receivable balances through rental income as a result of transitioning facilities between existing operators. As of June 30, 2023, we had 18 operators on a cash basis for revenue recognition, which represent 25.8% and 32.3% of our total revenues (excluding the impact of write-offs) for the six months ended June 30, 2023 and 2022, respectively. Rent Deferrals and Application of Collateral During the six months ended June 30, 2023 and 2022, we allowed nine operators and seven operators, respectively, to defer $33.6 million and $24.0 million, respectively, of contractual rent and interest. The deferrals during the six months ended June 30, 2023 primarily related to the following operators: LaVie ($19.0 million), Healthcare Homes Limited (“Healthcare Homes”) ($8.2 million), Agemo Holdings, LLC (“Agemo”) ($1.9 million) and Maplewood Senior Living (along with affiliates, “Maplewood”) ($0.7 million). Additionally, we allowed four operators and five operators to apply collateral, such as security deposits or letters of credit, to contractual rent and interest during the six months ended June 30, 2023 and 2022, respectively. The total collateral applied to contractual rent and interest was $5.5 million and $4.7 million for the six months ended June 30, 2023 and 2022, respectively. Operator Collectibility Updates Agemo In the first quarter of 2023, Omega and Agemo entered into a restructuring agreement, an amended and restated master lease and a new loan agreement for two replacement loans. As part of the restructuring agreement and related agreements, Omega agreed to, among other things: ● Forgive and release Agemo from previously written off past due rent and interest obligations related to certain periods prior to the 2018 Agemo restructuring and from August 2021 through January 2023, with contractual rent under the lease agreement and contractual interest under the loan agreements scheduled to resume on April 1, 2023; ● reduce monthly contractual base rent from $4.8 million to $1.9 million following the sales of 22 facilities, previously leased and operated by Agemo, that occurred in the third and fourth quarters of 2022; ● extend the initial Agemo lease term from December 31, 2030 , to December 31, 2036 with three consecutive tenant 10-year extension options; and ● refinance and restructure the $25.0 million secured working capital loan (the “Agemo WC Loan”), the $32.0 million term loan (the “Agemo Term Loan”) and the aggregate deferred rent balance of $25.2 million into two replacement loans to Agemo that mature on December 31, 2036 , with aggregate principal of $82.2 million and an annual interest rate of 5.63% through October 2024, which increases to 5.71% until maturity. Agemo resumed making contractual rent payments during the second quarter of 2023 in accordance with the restructuring terms discussed above. Agemo is on a cash basis of revenue recognition for lease purposes, and we recorded rental income of $5.8 million for the three and six months ended June 30, 2023 for the contractual rent payments that were received. Additionally, no interest income was recognized during the three and six months ended June 30, 2023 and 2022 on the two loans with Agemo because these loans are on non-accrual status and we are utilizing the cost recovery method, under which any payments, if received, are applied against the principal amount. See Note 6 – Non-Real Estate Loans Receivable for further discussion on the impact of the restructuring on the loans. LaVie In the first quarter of 2023, Omega continued the process of restructuring our portfolio with LaVie and entered into lease amendments that allow for a partial rent deferral for the first four months of 2023. In doing so, we agreed to allow LaVie to defer up to $19.1 million of contractual rent from January 2023 through April 2023 under our lease agreements. During the three and six months ended June 30, 2023, LaVie elected to defer $4.7 million and $19.0 million, respectively, of contractual rent. Since LaVie was placed on a cash basis of revenue recognition for lease purposes in the fourth quarter of 2022, the $16.9 million and $24.3 million of contractual rent payments that we received from LaVie to satisfy the remaining contractual obligations after utilizing the deferral were recorded as rental income during the three and six months ended June 30, 2023, respectively. During the second quarter of 2023, we transitioned two facilities, previously subject to the master lease with LaVie, to another operator. In July 2023, LaVie paid $2.5 million of contractual rent, a short pay of $4.7 million of the $7.2 million due under its lease agreement. Revenue from LaVie represents approximately 5.1% and 11.3% of our total revenues (excluding the impact of write-offs) for the six months ended June 30, 2023 and 2022, respectively. Maplewood In the first quarter of 2023, we agreed to a formal restructuring agreement, master lease amendments and loan amendments with Maplewood. As part of the restructuring agreement and related agreements, Omega agreed to, among other things: ● Extend the maturity date of the master lease from December 2033 to December 2037 with two consecutive 5-year tenant extension options; ● fix contractual rent at $69.3 million per annum (December 2022 rent annualized) and defer the 2.5% annual escalators under our lease agreement through December 31, 2025, with mandatory repayments to be made subject to certain metrics and due in full by the maturity date; ● fund $22.5 million of capital expenditures through December 31, 2025; ● extend the maturity date of the secured revolving credit facility from June 2030 to June 2035 with one borrower 2-year extension option; ● increase the capacity of the secured revolving credit facility from $250.5 million to $320.0 million, inclusive of payment-in-kind (“PIK”) interest applied to principal ; ● convert the 7% per annum cash interest due on the secured revolving credit facility to all PIK interest in 2023, 1% cash interest and 6% PIK interest in 2024, 4% cash interest and 3% PIK interest in 2025 and through the maturity date; ● pay a one-time option termination fee of $12.5 million to Maplewood; and ● reduce Maplewood’s share of any future potential sales proceeds (in excess of our gross investment) by the unpaid deferred rent balance, the $22.5 million of capital expenditures and the $12.5 million option termination fee payment. Maplewood short-paid the contractual rent amount due under its lease agreement in each of June 2023 and July Healthcare Homes In December 2022, we agreed to allow Healthcare Homes, a U.K.-based operator representing 3.1% and 2.9% of our total revenues (excluding the impact of write-offs) for the six months ended June 30, 2023 and 2022, respectively, the ability to defer up to £6.7 million of contractual rent from January 2023 through April 2023 with regular payments required to resume in May 2023. The deferred rent balance accrues interest monthly at a rate of 8% per annum and must be fully repaid by December 31, 2024. During the three and six months ended June 30, 2023, Healthcare Homes elected to defer £1.7 million ($2.1 million in USD) and £6.7 million ($8.2 million in USD), respectively, of contractual rent in accordance with the December 2022 agreement. Healthcare Homes is on a straight-line basis of revenue recognition. In May 2023, Healthcare Homes resumed making full contractual rent payments.

REAL ESTATE LOANS RECEIVABLE [Abstract]
REAL ESTATE LOANS RECEIVABLE	NOTE 5 – REAL ESTATE LOANS RECEIVABLE Real estate loans consist of mortgage notes and other real estate loans which are primarily collateralized by a first, second or third mortgage lien or a leasehold mortgage on, or an assignment of the partnership interest in the related properties. As of June 30, 2023, our real estate loans receivable consists of eight fixed rate mortgage notes on 49 long-term care facilities and 12 other real estate loans. The mortgage notes relate to facilities located in six states that are operated by seven independent healthcare operating companies. We monitor compliance with our real estate loans and, when necessary, have initiated collection, foreclosure and other proceedings with respect to certain outstanding real estate loans. The principal amounts outstanding of real estate loans receivable, net of allowances, were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ ​ 2023 2022 ​ ​ (in thousands) ​ Mortgage notes due 2030; interest at 11.01% (1) ​ $ 509,475 $ 506,321 ​ Mortgage note due 2031; interest at 11.27% ​ ​ — ​ ​ 76,049 ​ Mortgage note due 2037; interest at 10.50% (2) ​ ​ 72,420 ​ ​ 72,420 ​ Mortgage note due 2025; interest at 7.85% ​ ​ 62,921 ​ ​ 63,811 ​ Other mortgage notes outstanding (3) ​ 25,622 ​ 12,922 ​ Mortgage notes receivable – gross ​ 670,438 ​ 731,523 ​ Allowance for credit losses on mortgage notes receivable ​ ​ (40,226) ​ ​ (83,393) ​ Mortgage notes receivable – net ​ ​ 630,212 ​ ​ 648,130 ​ Other real estate loan due 2035; interest at 7.00% ​ ​ 263,520 ​ ​ 250,500 ​ Other real estate loans due 2024; interest at 13.19% (1) ​ ​ 102,535 ​ ​ 98,440 ​ Other real estate loans due 2023-2029; interest at 11.75% (1) ​ ​ 103,307 ​ ​ 43,628 ​ Other real estate loan outstanding (4) ​ ​ 20,000 ​ ​ 20,000 ​ Other real estate loans – gross ​ ​ 489,362 ​ ​ 412,568 ​ Allowance for credit losses on other real estate loans ​ (22,768) ​ (17,967) ​ Other real estate loans – net ​ ​ 466,594 ​ ​ 394,601 ​ Total real estate loans receivable – net ​ $ 1,096,806 ​ $ 1,042,731 ​ (1) Approximates the weighted average interest rate on facilities as of June 30, 2023. (2) During the second quarter of 2023, this mortgage note was extended from December 31, 2032 to December 31, 2037. (3) Other mortgage notes outstanding have a weighted average interest rate of 8.6% as of June 30, 2023, with maturity dates ranging from 2023 through 2026 . Two of the mortgage notes with an aggregate principal balance of $12.9 million are past due and have been written down, through our allowance for credit losses, to the estimated fair value of the underlying collateral of $1.5 million. (4) As of June 30, 2023 and December 31, 2022, includes one other real estate loan that bears interest at a rate of 12% and matures on December 2, 2027 . Interest revenue on real estate loans is included within interest income on the Consolidated Statements of Operations and is summarized as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended June 30, ​ Six Months Ended June 30, ​ 2023 2022 ​ 2023 2022 ​ (in thousands) ​ (in thousands) Mortgage notes – interest income $ 16,998 $ 19,597 ​ $ 33,546 $ 40,146 Other real estate loans – interest income 6,981 ​ 9,042 ​ 13,830 ​ 17,421 Total real estate loans interest income $ 23,979 ​ $ 28,639 ​ $ 47,376 ​ $ 57,567 ​ Mortgage note due 2031 In the second quarter of 2022, we agreed to a formal restructuring agreement and amended the mortgage loan with Guardian, which among other adjustments, extended the loan’s maturity date and allowed for the deferral of certain contractual interest. The loan amendment was treated as a loan modification provided to a borrower experiencing financial difficulty. Following the execution of the restructuring agreement, Guardian resumed paying contractual rent and interest during the second quarter of 2022 and continued such payments throughout the remainder of 2022 and the first and second quarters of 2023, in accordance with the restructuring terms. The mortgage loan is on non-accrual status and is being accounted for under the cost recovery method, under which any payments, if received, are applied against the principal amount. During the three and six months ended June 30, 2023, we received $1.6 million and $3.9 million, respectively, of interest payments from Guardian that we applied against the outstanding principal of the loan and recognized a recovery for credit loss equal to the amount of payments applied against principal. In the second quarter of 2023, Guardian completed the sale of the four remaining facilities subject to the mortgage note with Omega. Guardian used $35.2 million of proceeds from the sale of the facilities to make a principal repayment to Omega, in the same amount, against the mortgage note. Following the repayment, Omega agreed to release the mortgage liens on these facilities and forgive the remaining $46.8 million of outstanding principal due under the mortgage note. We had previously established an allowance for credit loss to reserve this loan down to $35.2 million in anticipation of this settlement. Other real estate loan due 2035 As discussed in Note 4 – Contractual Receivables and Other Receivables and Lease Inducements, in the first quarter of 2023, Omega entered into a restructuring agreement and a loan amendment with Maplewood that modified Maplewood’s secured revolving credit facility. As part of the restructuring agreement and loan amendment, Omega agreed to extend the maturity date of the facility to June 2035, increase the capacity of the secured revolving credit facility from $250.5 million to $320.0 million, including PIK interest applied to the principal, and to convert the 7% cash interest due on the secured revolving credit facility to all PIK interest in 2023, 1% cash interest and 6% PIK interest in 2024, 4% cash interest and 3% PIK interest in 2025 and through the maturity date. The maximum PIK interest allowable under credit facility, as amended, is $52.2 million. This amendment was treated as a loan modification provided to a borrower experiencing financial difficulty. During the three months ended March 31, 2023, we recorded interest income of $1.5 million on the secured revolving credit facility for the contractual interest payment received related to December 2022, as the loan was placed on non-accrual status for interest recognition during the fourth quarter of 2022. We did not record any interest income related to the PIK interest during the three and six months ended June 30, 2023. As of June 30, 2023, the amortized cost basis of this loan was $263.5 million, which represents 22.7% of the total amortized cost basis of all real estate loan receivables. As of June 30, 2023, the remaining commitment under the secured revolving credit facility, including the unrecognized PIK interest, was $48.8 million. Other real estate loans due 2023-2029 On April 14, 2023, we entered into two mezzanine loans, with principal balances of $68.0 million and $6.6 million, respectively, with an existing operator and its affiliates in connection with the operator’s acquisition of 13 SNFs in West Virginia. The $68.0 million loan matures on April 13, 2029 and bears interest at a variable rate that results in a blended interest rate of 12% per annum across this loan and three other loans, including the $6.6 million mezzanine loan and both

NON-REAL ESTATE LOANS RECEIVABLE [Abstract]
NON-REAL ESTATE LOANS RECEIVABLE	NOTE 6 – NON-REAL ESTATE LOANS RECEIVABLE Our non-real estate loans consist of fixed and variable rate loans to operators and/or principals. These loans may be either unsecured or secured by the collateral of the borrower, which may include the working capital of the borrower. As of June 30, 2023, we had 39 loans with 22 different borrowers. A summary of our non-real estate loans is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ ​ 2023 2022 ​ ​ ​ (in thousands) ​ Notes due 2023-2029; interest at 11.30% (1) ​ $ 86,763 ​ $ 55,981 ​ Notes due 2036; interest at 5.63% ​ ​ 80,207 ​ 55,791 ​ Notes due 2036; interest at 2.00% ​ ​ 32,308 ​ ​ 32,539 ​ Note due 2024; interest at 7.50% ​ ​ 50,999 ​ ​ 47,999 ​ Note due 2027; interest at 12.00% (2) ​ ​ — ​ ​ 39,653 ​ Other notes outstanding (3) ​ 93,318 ​ 77,186 ​ Non-real estate loans receivable – gross ​ ​ 343,595 ​ ​ 309,149 ​ Allowance for credit losses on non-real estate loans receivable ​ ​ (115,679) ​ ​ (83,868) ​ Total non-real estate loans receivable – net ​ $ 227,916 ​ $ 225,281 ​ (1) Approximates the weighted average interest rate as of June 30, 2023. (2) During the first quarter of 2023, this loan was fully repaid. (3) Other notes outstanding have a weighted average interest rate of 7.39% as of June 30, 2023, with maturity dates ranging from 2023 through 2030 (with $19.6 million maturing in 2023 ). We have one loan within other notes outstanding with principal of $4.1 million that matured in 2022 but remained outstanding as of June 30, 2023. We wrote the $4.1 million loan down to the fair value of its collateral of $1.0 million during the first quarter of 2023. For the three months ended June 30, 2023 and 2022, non-real estate loans generated interest income of $5.3 million and $2.8 million, respectively. For the six months ended June 30, 2023 and 2022, non-real estate loans generated interest income of $10.3 million and $5.0 million, respectively. Interest income on non-real estate loans is included within interest income on the Consolidated Statements of Operations. Notes due 2036 ; interest at 5.63% As discussed in Note 4 – Contractual Receivables and Other Receivables and Lease Inducements, in the first quarter of 2023, Omega entered into a restructuring agreement and a replacement loan agreement that modified the existing Agemo loans. Under the restructuring agreement, previously written off contractual unpaid interest related to the Agemo WC Loan and the Agemo Term Loan was forgiven. The outstanding principal of the Agemo Term Loan was refinanced into a new $32.0 million loan (“Agemo Replacement Loan A”). The outstanding principal of the Agemo WC Loan and the aggregate rent deferred and outstanding under the Agemo lease agreement was combined and refinanced into a new $50.2 million loan (“Agemo Replacement Loan B” and with Agemo Replacement Loan A, the “Agemo Replacement Loans”). The Agemo Replacement Loans bear interest at 5.63% per annum through October 2024, which increases to 5.71% per annum until maturity. The Agemo Replacement Loans mature on December 31, 2036. Interest payments were scheduled to resume on April 1, 2023, contingent upon Agemo’s compliance with certain conditions of the restructuring agreement; however, Agemo had the option to defer the interest payment due on April 1, 2023. Beginning in January 2025, Agemo will be required to make principal payments on the Agemo Replacement Loans dependent on certain metrics. These amendments were treated as loan modifications provided to a borrower experiencing financial difficulty. Both of these loans are on non-accrual status, and we are utilizing the cost recovery method, under which any payments, if received, are applied against the principal amount. Prior to the restructuring, the principal of the Agemo WC Loan and the Agemo Term Loan were written down to $5.9 million and zero, respectively, the fair value of the underlying collateral of these loans. No changes to the collateral supporting the loans were made because of the refinancing of these loans into the Agemo Replacement Loans. Additional principal of $25.2 million related to deferred rent due under the master lease was combined with the principal of the Agemo WC Loan under Agemo Replacement Loan B. This deferred rent balance was previously written off when the Agemo master lease was taken to a cash basis of revenue recognition in 2020. We believe it is not probable that we will collect the additional $25.2 million of principal balance associated with the deferred rent under Agemo Replacement Loan B. As such, we added an additional allowance for credit losses of $25.2 million related to Agemo Replacement Loan B concurrent with the increase in loan principal during the first quarter of 2023. There is no income statement impact as a result of this additional reserve due to the balance previously being written off. Agemo exercised its option to defer the interest payment due on April 1, 2023 and resumed making interest payments in May 2023 in accordance with the restructuring terms discussed above. During the three months ended June 30, 2023, we received $0.8 million of interest payments from Agemo that we applied against the outstanding principal of the loans and recognized a recovery for credit loss equal to the amount of payments applied against principal. As of June 30, 2023, the amortized cost basis of these loans was $80.2 million, which represents 23.3% of the total amortized cost basis of all non-real estate loan receivables. The total reserve as of June 30, 2023 related to the Agemo Replacement Loans was $74.3 million. Notes due 2023 - 2029 During the second quarter of 2023, we entered into two Notes due 2036 ; interest at 2.00% During the fourth quarter of 2022, we amended an $8.3 million term loan and a $25.0 million term loan with LaVie to, among other terms, extend the loan maturities to November 30, 2036 to align with the lease term, and starting in January 2023, reduce the interest rates to 2%, remove the requirement to make any principal payments until the maturity dates and convert from monthly cash interest payments to PIK interest. These amendments were treated as loan modifications provided to a borrower experiencing financial difficulty. Both of these loans are on non-accrual status, and we are utilizing the cost recovery method, under which any payments made by LaVie are applied against the principal amount outstanding. During the six months ended June 30, 2023, we applied an aggregate $0.2 million of interest payments received to the $25.0 million term loan principal balance and the $8.3 million term loan principal balance outstanding. Note due 2024 On July 8, 2019, the Company entered into a $15 million unsecured revolving credit facility agreement with a principal of an operator that bears interest at a fixed rate of 7.5% per annum and originally matured on July 8, 2022. During 2022, this revolving credit facility was amended multiple times to increase the maximum principal to $48 million, extend the maturity date to December 31, 2024 and require monthly principal payments. During the second quarter of 2023, this revolving credit facility was further amended to increase the maximum principal to $52 million and modify the principal payment schedule. Other notes outstanding $10.0 million Mezzanine Loan and Working Capital Loan On June 30, 2023, the Company entered into a $10.0 million mezzanine loan and a revolving working capital loan with an existing operator in connection with the operator’s acquisition of a portfolio of facilities in Pennsylvania. The $10.0 million mezzanine loan matures on June 30, 2028 and bears interest at a fixed rate of 11% per annum. The $10.0 million mezzanine loan also requires monthly amortizing payments of principal and interest in the amount of $0.2 million. The $10.0 million mezzanine loan is secured by an equity interest in a subsidiary of the operator.

Variable Interest Entities [Abstract]
VARIABLE INTEREST ENTITIES	NOTE 8 – VARIABLE INTEREST ENTITIES Unconsolidated Variable Interest Entities We hold variable interests in several VIEs through our investing and financing activities, which are not consolidated, as we have concluded that we are not the primary beneficiary of these entities as we do not have the power to direct activities that most significantly impact the VIE’s economic performance and/or the variable interest we hold does not obligate us to absorb losses or provide us with the right to receive benefits from the VIE which could potentially be significant. Below is a summary of our assets, liabilities, collateral and maximum exposure to loss associated with these unconsolidated VIEs as of June 30, 2023 and December 31, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ ​ ​ 2023 ​ 2022 ​ ​ ​ (in thousands) ​ Assets ​ ​ ​ ​ ​ ​ ​ Real estate assets – net ​ $ 1,047,319 ​ $ 982,721 ​ Real estate loans receivable – net ​ 302,816 ​ ​ 270,500 ​ Investments in unconsolidated joint ventures ​ ​ 8,150 ​ ​ — ​ Non-real estate loans receivable – net ​ 9,095 ​ ​ 5,929 ​ Contractual receivables – net ​ 194 ​ ​ 114 ​ Other assets ​ ​ 1,423 ​ ​ 1,499 ​ Total assets ​ 1,368,997 ​ 1,260,763 ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities ​ ​ ​ ​ ​ ​ ​ Accrued expenses and other liabilities ​ ​ (51,464) ​ ​ (50,522) ​ Total liabilities ​ (51,464) ​ (50,522) ​ ​ ​ ​ ​ ​ ​ ​ ​ Collateral ​ ​ ​ Personal guarantee ​ (48,000) ​ ​ (48,000) ​ Other collateral (1) ​ (1,060,019) ​ ​ (982,721) ​ Total collateral ​ (1,108,019) ​ ​ (1,030,721) ​ ​ ​ ​ ​ ​ ​ ​ ​ Maximum exposure to loss ​ $ 209,514 ​ $ 179,520 ​ (1) Amount excludes accounts receivable that Omega has a security interest in as collateral under the three loans with operators that are unconsolidated VIEs. The fair value of the accounts receivable available to Omega was $8.7 million and $5.9 million as of June 30, 2023 and December 31, 2022, respectively. In determining our maximum exposure to loss from the unconsolidated VIEs, we considered the underlying carrying value of the real estate subject to leases with the operator and other collateral, if any, supporting our other investments, which may include accounts receivable, security deposits, letters of credit or personal guarantees, if any, as well as other liabilities recognized with respect to these operators. The table below reflects our total revenues from the operators that are considered unconsolidated VIEs for the three and six months ended June 30, 2023 and 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended June 30, ​ Six Months Ended June 30, ​ 2023 ​ 2022 ​ 2023 ​ 2022 ​ (in thousands) ​ (in thousands) Revenue ​ ​ ​ ​ Rental income $ 25,962 ​ $ 21,239 ​ $ 35,800 ​ $ 42,102 Interest income 979 ​ 4,335 ​ 3,085 ​ 8,101 Total $ 26,941 ​ $ 25,574 ​ $ 38,885 ​ $ 50,203 ​ Consolidated VIEs We own 52.4% of the outstanding equity of a joint venture, which owns two ALFs, that is a VIE. We have consolidated this VIE as a result of our conclusion that we are the primary beneficiary of this VIE based on a combination of our ability to direct the activities that most significantly impact the joint venture’s economic performance and our rights to receive residual returns or the obligation to absorb losses arising from the joint venture. As of June 30, 2023 and December 31, 2022, this joint venture has $26.7 million and $25.8 million, respectively, of total assets and $20.3 million and $19.8 million, respectively, of total liabilities, which are included in our Consolidated Balance Sheets. During the fourth quarter of 2022, we acquired seven facilities using a reverse like-kind exchange structure pursuant to Section 1031 of the Code (a “reverse 1031 exchange”). We completed the reverse 1031 exchange for three of the acquired facilities in the fourth quarter of 2022. During the second quarter of 2023, the remaining four facilities were released from the possession of the Exchange Accommodation Titleholders (“EATs”), as we did not identify any qualifying exchange transactions. The EATs were classified as VIEs as they did not have sufficient equity investment at risk to permit the entity to finance its activities. The Company consolidated the EATs because it had the ability to control the activities that most significantly impacted the economic performance of the EATs and was, therefore, the primary beneficiary of the EATs. The properties held by the EATs were reflected as real estate with a carrying value of $55.2 million as of December 31, 2022. The EATs also held cash of $23.9 million as of December 31, 2022

Taxes [Abstract]
TAXES	NOTE 13 – TAXES Omega was organized, has operated and intends to continue to operate in a manner that enables Omega to qualify for taxation as a REIT under Sections 856 through 860 of the Code. On a quarterly and annual basis, we perform several analyses to test our compliance within the REIT taxation rules. If we fail to meet the requirements for qualification as a REIT in any tax year, we will be subject to federal income tax on our taxable income at regular corporate rates and may not be able to qualify as a REIT for the four We are also subject to federal taxation of 100% of the net income derived from the sale or other disposition of property, other than foreclosure property, that we held primarily for sale to customers in the ordinary course of a trade or business. We believe that we do not hold assets for sale to customers in the ordinary course of business and that none of the assets currently held for sale or that have been sold would be considered a prohibited transaction within the REIT taxation rules. As a REIT under the Code, we generally will not be subject to federal income taxes on the REIT taxable income that we distribute to stockholders, subject to certain exceptions. In 2022, we distributed dividends in excess of our taxable income. We currently own stock in certain subsidiary REITs. These subsidiaries are required to individually satisfy all of the rules for qualification as a REIT. If we fail to meet the requirements for qualification as a REIT for any of the subsidiary REITs, it may cause Omega to fail the requirements for qualification as a REIT also. We have elected to treat certain of our active subsidiaries as taxable REIT subsidiaries (“TRSs”). Our domestic TRSs are subject to federal, state and local income taxes at the applicable corporate rates. As of June 30, 2023, one of our TRSs that is subject to income taxes at the applicable corporate rates had a net operating loss (“NOL”) carry-forward of approximately $10.2 million. Our NOL carry-forward was fully reserved as of June 30, 2023, with a valuation allowance due to uncertainties regarding realization. Under current law, NOL carry-forwards generated up through December 31, 2017, may be carried forward for no more than 20 years, and NOL carry-forwards generated in taxable years ended after December 31, 2017, may be carried forward indefinitely. We do not anticipate that such changes will materially impact the computation of Omega’s taxable income, or the taxable income of any Omega entity, including our TRSs. Our foreign subsidiaries are subject to foreign income taxes and withholding taxes. As of June 30, 2023, one of our U.K. subsidiaries had a NOL carryforward of approximately $42.2 million. The NOLs have no expiration date and may be available to offset future taxable income. We believe these foreign NOLs are realizable under a “more likely than not” measurement and have not recorded a valuation allowance against the deferred tax asset. The majority of our U.K. portfolio elected to enter the U.K. REIT regime with an effective date of April 1, 2023. In connection with entering the U.K. REIT regime, we recognized several adjustments to our deferred tax balances in the first quarter of 2023 as summarized below. The following is a summary of deferred tax assets and liabilities (which are recorded in other assets and accrued expenses and other liabilities in our Consolidated Balance Sheets): ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2023 2022 ​ ​ (in thousands) U.S. Federal net operating loss carryforward ​ $ 2,138 ​ $ 2,138 Valuation allowance on deferred tax asset ​ (2,138) ​ (2,138) Foreign net operating loss carryforward ​ ​ 10,544 ​ ​ 11,268 Foreign deferred tax liability (1) ​ — ​ (5,373) Net deferred tax asset ​ $ 10,544 ​ $ 5,895 ​ ​ ​ ​ ​ ​ ​ Foreign deferred tax liability (2) ​ $ 1,422 ​ $ — Net deferred tax liability ​ $ 1,422 ​ $ — (1) The deferred tax liability primarily resulted from inherited basis differences resulting from our acquisition of entities in the U.K. Subsequent adjustments to these accounts result from GAAP to tax differences related to depreciation, indexation and revenue recognition. The foreign deferred tax liabilities were eliminated upon the majority of our U.K. portfolio entering the U.K. REIT regime. (2) The deferred tax liability resulted from book to tax differences recorded in the U.S. relating to depreciation and revenue recognition in the U.K. recognized upon the majority of our U.K. portfolio entering the U.K. REIT regime.

DERIVATIVES AND HEDGING

DERIVATIVES AND HEDGING [Abstract]
DERIVATIVES AND HEDGING	NOTE 16 – DERIVATIVES AND HEDGING We are exposed to, among other risks, the impact of changes in foreign currency exchange rates as a result of our investments in the U.K. and interest rate risk related to our capital structure. As a matter of policy, we do not use derivatives for trading or speculative purposes. Our risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes foreign currency forward contracts, interest rate swaps and debt issued in foreign currencies to offset a portion of these risks. As of June 30, 2023, we have one interest rate swap with $50.0 million in notional value that was entered into during the second quarter of 2023 (discussed further below). The swap is designated as a cash flow hedge. Additionally, we have six foreign currency forward contracts with £250.0 million in notional valued issued at a weighted average GBP-USD forward rate of 1.3641 that are designated as net investment hedges. In June 2023, we entered into an interest rate swap with a notional amount of $50.0 million. The swap is effective June 30, 2023 and terminates on April 30, 2027 . This interest rate swap is designated as a hedge against our exposure to changes in interest payment cash flow fluctuations in the variable interest rates on the OP Term Loan. The interest rate swap contract effectively converts our $50.0 million OP Term Loan to an aggregate fixed rate of approximately 5.52% through its maturity. The effective fixed rate achieved by the combination of the 2021 Omega OP Credit Agreement and the interest rate swaps could fluctuate up by 40 basis points or down by 60 basis points based on future changes to our credit ratings. In March 2020, we entered into five forward starting swaps with $400 million in notional value, indexed to 3-month LIBOR, that were issued at a weighted average fixed rate of 0.8675% and were subsequently designated as cash flow hedges. In conjunction with the October 2020 issuance of $700 million of 3.375% Senior Notes due 2031 and the March 2021 issuance of $700 million of 3.25% Senior Notes due 2033, we applied hedge accounting for these five forward starting swaps and began amortization. Simultaneously with these issuances, we re-designated these swaps in new cash flow hedging relationships of interest rate risk associated with interest payments for a future forecasted issuance of long-term debt. As a result of these transactions, the aggregate unrealized gain of $41.2 million ( $9.5 million gain related to the October 2020 issuance and $31.7 million gain related to the March 2021 issuance) included within accumulated other comprehensive income at the time of the bond issuances is being ratably reclassified as a reduction to interest expense, net over 10 years. On May 30, 2023, the five forward starting swaps were terminated, and Omega received a net cash settlement of $92.6 million from the swap counterparties. The incremental $51.4 million of gains related to the forward swaps, recorded in accumulated other comprehensive income, were frozen at the time of termination and will be recognized ratably over 10 years in earnings when the next qualifying debt issuance occurs. Consistent with our accounting policy and historical practice, the $92.6 million net cash settlement from the forward swap termination is reflected within net cash used in financing activities in the Consolidated Statements of Cash Flows. The location and fair value of derivative instruments designated as hedges, at the respective balance sheet dates, were as follows: ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2023 2022 Cash flow hedges: (in thousands) Other assets $ 211 ​ $ 92,990 ​ ​ ​ ​ ​ ​ Net investment hedges: ​ ​ ​ ​ ​ Other assets $ 25,921 ​ $ 34,977 ​ The fair value of the interest rate swap and foreign currency forwards is derived from observable market data such as yield curves and foreign exchange rates and represents a Level 2 measurement on the fair value hierarchy.

The fair values of notes receivable are estimated using a discounted cash flow analysis, using interest rates being offered for similar loans to borrowers with similar credit ratings (Level 3). ● Revolving credit facility, OP term loan, 2023 term loan and 2024 term loan: The carrying amount of these approximate fair value because the borrowings are interest rate adjusted. Differences between carrying value and the fair value in the table above are due to the inclusion of deferred financing costs in the carrying value. ● Senior notes: The fair value of the senior unsecured notes payable was estimated based on (Level 1) publicly available trading prices. ● HUD mortgages: The fair value of our borrowings under HUD debt agreements are estimated using an expected present value technique based on quotes obtained by HUD debt brokers (Level 2).

COMMITMENTS AND CONTINGENCIES [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 18 – COMMITMENTS AND CONTINGENCIES Litigation Shareholder Litigation The Company and certain of its officers, C. Taylor Pickett, Robert O. Stephenson, and Daniel J. Booth Certain derivative actions have also been brought against the officers named in the Securities Class Action, and certain current and former directors of the Company, alleging claims relating to the matters at issue in the Securities Class Action. In 2018, Stourbridge Investments LLC, a purported stockholder of the Company, filed a derivative action purportedly on behalf of the Company in the U.S. District Court for the Southern District of New York, alleging violations of Section 14(a) of the Exchange Act and state-law claims including breach of fiduciary duty. The complaint alleges, among other things, that the named defendants are responsible for the Company’s failure to disclose the financial condition of Orianna Health Systems, the alleged non-disclosures that were also the subject of the Securities Class Action described above. The plaintiff did not make a demand on the Company to bring the action prior to filing it, but rather alleges that demand would have been futile. In 2019, purported stockholder Phillip Swan by his counsel, and stockholders Tom Bradley and Sarah Smith by their counsel, filed derivative actions in the Baltimore City Circuit Court of Maryland, purportedly on behalf of the Company, asserting claims for breach of fiduciary duty, waste of corporate assets and unjust enrichment against the named defendants. Those actions were consolidated. Prior to filing suit, each of these stockholders had made demands on the Board of Directors in 2018 that the Company bring such lawsuits. After an investigation and due consideration, and in the exercise of its business judgment, the Board of Directors determined that it is not in the best interests of the Company to commence litigation against any current or former officers or directors based on the matters raised in the demands. In addition, in late 2020, Robert Wojcik, a purported shareholder of the Company, filed a derivative action in the U.S. District Court for the District of Maryland, purportedly on behalf of the Company, asserting violations of Section 14(a) of the Exchange Act, Sections 10(b) and 21D of the Exchange Act, as well as claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. Wojcik also did not make a demand on the Company prior to filing suit. Other Gulf Coast Subordinated Debt In August 2021, we filed suit in the Circuit Court for Baltimore County (the “Court”) against the holders of certain Subordinated Debt (the “Debt Holders”) associated with our Gulf Coast master lease agreement, following an assertion by the Debt Holders that our prior exercise of offset rights in connection with Gulf Coast’s non-payment of rent had resulted in defaults under the terms of the Subordinated Debt. The suit seeks a declaratory judgment to, among other items, declare that the aggregate amount of unpaid rent due from Gulf Coast under the master lease agreement exceeds all amounts which otherwise would be due and owing by an indirect subsidiary of Omega (“Omega Obligor”) under the Subordinated Debt, and that all principal and interest due and owing under the Subordinated Debt may be (and was) offset in full as of December 31, 2021. In October 2021, the Debt Holders filed a motion to dismiss for lack of personal jurisdiction. On November 3, 2022, the Court granted the Debt Holders’ motion to dismiss for lack of personal jurisdiction, and Omega filed a timely appeal of the ruling. While Omega believes Omega Obligor is entitled to the enforcement of the offset rights sought in the action, Omega cannot predict the outcome of the declaratory judgment action, irrespective of whether (a) it is ultimately litigated in the Court if Omega Obligor prevails in its appeal or (b) if the order granting the motion to dismiss for lack of personal jurisdiction is affirmed and the issues are litigated in the Delaware Court (as defined below). On or about January 19, 2023, the Debt Holders served a lawsuit against the Omega Obligor in the Superior Court of the State of Delaware (the “Delaware Court”), asserting claims for (i) breach of the instruments evidencing the Subordinated Debt, (ii) declaratory judgment, and (iii) unjust enrichment, all claims that are factually based on the claims that are the subject of Omega Obligor’s suit in the Court and that are now on appeal. On February 8, 2023, Omega Obligor filed a motion to dismiss or, in the alternative, to stay this action pending the outcome of the above-referenced lawsuit in Maryland. On July 10, 2023, the Delaware state court case stayed the proceeding pending a hearing in September 2023. Omega believes that the claims are baseless and is evaluating procedural and substantive legal options in connection with this recently filed suit to the extent the stay is lifted. Other In addition to the matters above, we are subject to various other legal proceedings, claims and other actions arising out of the normal course of business. While any legal proceeding or claim has an element of uncertainty, management believes that the outcome of each lawsuit, claim or legal proceeding that is pending or threatened, or all of them combined, will not have a material adverse effect on our consolidated financial position or results of operations. Indemnification Agreements In connection with certain facility transitions, we have agreed to indemnify certain operators in certain events. As of June 30, 2023, our maximum funding commitment under these indemnification agreements was approximately $9.1 million. Claims under these indemnification agreements generally may be made within 18 months to 72 months of the transition date. These indemnification agreements were provided to certain operators in connection with facility transitions and generally would be applicable in the event that the prior operators do not perform under their transition agreements. Commitments We have committed to fund the construction of new leased and mortgaged facilities, capital improvements and other commitments. We expect the funding of these commitments to be completed over the next several years. Our remaining commitments at June 30, 2023, are outlined in the table below (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Lessor construction and capital commitments under lease agreements ​ $ 230,162 ​ ​ Non-real estate loan commitments ​ 66,709 ​ ​ Other real estate loan commitments ​ 48,803 ​ ​ Construction and capital expenditure mortgage loan commitments ​ 8,036 ​ ​ Total remaining commitments (1) ​ $ 353,710 ​ ​ (1) Includes finance costs .
