KBRA Assigns Preliminary Ratings to J.P. Morgan Mortgage Trust 2021-INV1 (JPMMT 2021-INV1)

NEW YORK–() – The Kroll Bond Rating Agency (KBRA) assigns preliminary ratings to twenty-one classes of Mortgage Pass-Through Certificates from JP Morgan Mortgage Trust 2021-INV1 (JPMMT 2021-INV1), a premium RMBS transaction made up of 513 residential mortgages using The total face value as of May 1, 2021 was approximately $ 268.0 million. The underlying collateral includes prime non-compliant (44.6%) and compliant (55.4%) loans and is fully backed by investment property. The pool is characterized by significant borrower equity in each mortgage-backed property, as suggested by WA’s original CLTV of 59.2%. The weighted average initial credit score is 775, which is well in line with the home mortgage range.

KBRA’s rating approach included an analysis of the mortgage pool at the loan level through the KBRA RMBS credit model, a review of the results of the due diligence on third-party credit files, a cash flow model analysis of the payment structure of the transaction, reviews of the key transaction parties and an analysis of the legal structure and documentation of the transaction. This analysis is further described in our US RMBS rating methodology.
