KBRA assigns preliminary ratings to 10 classes of mortgage-backed certificates from GS Mortgage-Backed Securities Trust 2026-NQM1 (GSMBS 2026-NQM1).

GS Mortgage-Backed Securities Trust 2026-NQM1 (GSMBS 2026-NQM1), is a $410.6 million RMBS transaction sponsored by Goldman Sachs Mortgage Company (Goldman Sachs). The transaction is collateralized by a pool of 1,076 fixed-rate residential mortgages (FRM; 100.0%), and includes a meaningful concentration of collateral that KBRA considers to be “non-prime” (84.7%). Borrowers in the pool exhibit moderate equity in their mortgaged properties, with both the weighted-average LTV and combined LTV ratios of 70.5%. Most loans are either classified as non-qualified mortgages (Non-QM) (46.6%) or exempt (53.3%) from the Ability-to-Repay/Qualified Mortgage (ATR/QM) rule due to being originated for non-consumer loan purposes. United Wholesale Mortgage, LLC is the largest originator in the pool (UWM; 23.8%), with no other originator comprising more than 10.0% of the loans. Newrez LLC d/b/a Shellpoint Mortgage Servicing (SMS) and Select Portfolio Servicing, Inc. (SPS) will act as servicers for the transaction, servicing 98.3% and 1.7% of the pool, respectively.

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. This analysis is further described in our U.S. RMBS Rating Methodology.
