Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Schedule of Investment Groups | The Company's asset classes are primarily comprised of the following:
Asset Class |  | Description
Residential Investments
Non-Agency Loans(1) |  | •Non-Agency Loans are loans that do not conform to the underwriting guidelines of a government-sponsored enterprise ("GSE"). Non-Agency Loans consist of Qualified mortgage loans ("QM Loans") and Non-Qualified mortgage loans ("Non-QM Loans") which are collateralized by a first lien mortgaged property. QM Loans are residential mortgage loans that comply with the Ability-To-Repay rules and related guidelines of the Consumer Financial Protection Bureau.
Agency-Eligible Loans(1) |  | •Agency-Eligible Loans are loans that are collateralized by a first lien mortgaged property and are primarily secured by investment properties. These loans are underwritten in accordance with GSE guidelines, but are not guaranteed by a GSE. Although these loans are underwritten in accordance with GSE guidelines and can be delivered to Fannie Mae and Freddie Mac, the Company includes these loans within its Non-Agency securitizations.
Home Equity Loans(1) |  | •Home Equity Loans consist of revolving lines of credit and closed-end loans secured primarily by second liens on residential mortgaged properties. These products provide borrowers with access to home equity without requiring the payoff of an existing mortgage. Revolving lines of credit generally feature an initial draw period of 3 to 5 years, after which the balances convert to 15- or 25-year amortizing loans. Closed-end home equity loans are primarily fixed-rate obligations where the full principal amount is funded at origination and repaid through a fully amortizing schedule with original terms to maturity ranging from 10 to 30 years.
Re- and Non-Performing Loans(1) |  | •Performing, re-performing, and non-performing loans are residential mortgage loans collateralized by a first lien mortgaged property.
Non-Agency RMBS(2) |  | •Non-Agency Residential Mortgage-Backed Securities ("RMBS") represent fixed- and floating-rate RMBS issued by entities other than U.S. GSEs or agencies of the U.S. government. Non-Agency RMBS are primarily secured by Non-QM, Agency-Eligible, Home Equity, and Prime Jumbo Loans.
Agency RMBS(2) |  | •Agency RMBS represent interests in pools of residential mortgage loans guaranteed by a GSE such as Fannie Mae or Freddie Mac, or an agency of the U.S. Government such as Ginnie Mae.
Legacy WMC Commercial Investments(3)
Commercial Loans |  | •Commercial loans represent first lien commercial mortgage loan participations.
CMBS(2) |  | •Commercial Mortgage-Backed Securities ("CMBS") represent fixed-rate and floating-rate CMBS, secured by, or evidencing an ownership interest in, a single commercial mortgage loan or a pool of commercial mortgage loans.
(1)These investments are included in the "Securitized residential mortgage loans, at fair value" or "Residential mortgage loans, at fair value" line items on the consolidated balance sheets. (2)These investments are included in the "Real estate securities, at fair value" line item on the consolidated balance sheets. (3)These investments include commercial loans and CMBS (collectively, the "Legacy WMC Commercial Investments") that were acquired in connection with the acquisition of Western Asset Mortgage Capital Corporation ("WMC") on December 6, 2023. The Company expects to either hold the Legacy WMC Commercial Investments until maturity or opportunistically exit these investments.
