MDA DataQuick released a new product Monday to help lenders with residential mortgage-backed securities valuation. The product measures home loans based on underlying performance risks that have, in the past, been unknown, according to the San Diego-based real estate data provider. The program quantifies tax-delinquency status of a borrower, current collateral and property values, neighborhood default rates, borrower ownership and occupancy changes, additional liens, and updated loan-to-value ratios. The RMBS analysis product is supported through a pact MDA DataQuick has with MBSData, which is based in northern New Jersey and specializes in research of non-agency mortgage-backed securities. “Identifying post-origination changes in specific loans is critical in assessing accurate, current portfolio valuations,” said John Walsh, president of MDA DataQuick.  “In the past, this type of information has not been available.  By leveraging our existing data and analytics expertise and a partnership with MBSData, MDA DataQuick is now helping real estate lenders and investors better manage risk and restore confidence.” MDA DataQuick is a division of MDA Lending Solutions, which is based in Wilmington, Del., and provides data analysis to the mortgage industry.
