Kroll Bond Rating Agency (KBRA) assigns ratings to fifty-three classes of mortgage pass-through certificates from Sequoia Mortgage Trust 2018-8 (SEMT 2018-8), a prime RMBS transaction. SEMT 2018-7 contains both prime jumbo (78.3%) and high-balance conforming (21.7%) collateral to borrowers with prime attributes.
The SEMT 2018-8 mortgage pool is composed of 668 first-lien mortgage loans with an aggregate principal balance of $454,426,513 as of the cut-off date. The underlying collateral consists entirely of fully-amortizing, fixed-rate mortgages. The pool is characterized by substantial borrower equity in each mortgaged property, as evidenced by the WA original LTV of 68.1% and WA original CLTV of 68.5%. The weighted average original credit score is 772, which is within the prime mortgage range.
KBRAs rating approach incorporated loan-level analysis of the mortgage pool through its Residential Mortgage Default and Loss Model, an examination of the results from third-party loan file due diligence, cash flow modeling analysis of the transactions payment structure, reviews of key transaction parties and an assessment of the transactions legal structure and documentation. This analysis is further described in our U.S. RMBS Rating Methodology.
