KBRA Assigns Preliminary Ratings to Sequoia Mortgage Trust 2026-MED1 (SEMT 2026-MED1)

Contacts

KBRA assigns preliminary ratings to 23 classes of mortgage pass-through certificates from Sequoia Mortgage Trust 2026-MED1 (SEMT 2026-MED1). SEMT 2026-MED1 represents the first publicly-rated RMBS backed by loans originated pursuant to Physician or Doctor Loan underwriting programs. These loans, which KBRA generally refers to as Medical Professional Mortgages (MPM), typically originated through specialized prime mortgage programs designed for borrowers in the healthcare field whose earnings potential and income stability are high but where personal debt (typically student loan driven) is high and early career earnings and savings/down payment levels are low. SEMT 2026-MED1 is collateralized by a pool of 607 of such loans, aggregating $482.3 million in UPB, which are predominantly seven-year hybrid adjustable-rate mortgages (ARMs) (96.9% of the pool) with the remaining being fixed-rate mortgages (FRMs). A majority of the loans (95.3%) are designated as QM Safe Harbor (APOR).

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.
