KBRA assigns preliminary ratings to 61 classes of mortgage pass-through certificates from PMT Loan Trust 2024-INV1 (PMTLT 2024-INV1), a prime RMBS transaction sponsored by PennyMac Corp. (PennyMac), an indirect, wholly-owned subsidiary of PennyMac Mortgage Investment Trust (PMT). PMTLT 2024-INV1 comprises 981 fixed-rate mortgages (FRMs) with an aggregate principal balance of $354,015,189 as of the October 1, 2024 cut-off date. The underlying pool consists of agency-eligible loans that are collateralized by investment properties (77.2%) and second homes (22.8%). The pool is characterized by significant borrower equity in each mortgaged property, as evidenced by the WA original LTV of 74.2%. The weighted average original credit score is 776, which is well within the prime mortgage range.

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.
