KBRA Assigns Preliminary Ratings to OBX 2023-NQM1 Trust (OBX 2023-NQM1)


NEW YORK–(BUSINESS WIRE)–#KBRA–KBRA assigns preliminary ratings to six classes of mortgage pass-through notes from OBX 2023-NQM1 Trust (OBX 2023-NQM1), a $405.2 million non-prime RMBS transaction. The underlying collateral, comprising 842 residential mortgages, is characterized by a notable concentration of alternative income documentation (92.0%). Most loans are either classified as non-qualified mortgages (Non-QM) (62.9%) or exempt from the Ability-to-Repay/Qualified Mortgage (ATR/QM) rule due to being originated for non-consumer loan purposes (36.8%).

KBRA’s rating approach incorporated loan-level analysis of the mortgage pool through its KBRA RMBS Credit Model, 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.
