NEW YORK–(BUSINESS WIRE)–#creditratingagency–KBRA assigns preliminary ratings to eight classes of Certificates from COOPR Residential Mortgage Trust 2026-CES1 (COOPR 2026-CES1), a $253.3 million RMBS transaction, as of the cut-off date, sponsored by Nationstar Mortgage LLC d/b/a Mr. Cooper and Loan Funding Structure VIII LLC and consists almost entirely of 3,438 newly originated closed-end second lien mortgages (CES; 99.9%). The underlying pool is seasoned one month and all loans are originated by Mr. Cooper. The collateral consists of fully amortizing, fixed-rate mortgages (FRMs) with predominantly 20-year (78.9%), 30-year (9.1%), 15-year (8.2%), and 10-year (3.1%) maturity terms.

KBRA’s rating approach incorporated loan-level analysis of the mortgage pool through its Residential Asset Loss Model (REALM), an examination of the results from third-party loan file due diligence, cash flow modeling analysis of the transaction’s payment structure, reviews of key transaction parties and an assessment of the transaction’s legal structure and documentation.
