Aligning Fannie Mae’s and Freddie Mac’s underwriting standards and creating clear standards for representations and warranties is essential for a smooth transition to a sustainable secondary market operating with an explicit, limited government guaranty, according to the Mortgage Bankers Association. The MBA’s new concept paper – the fourth of a five-part plan – suggests the Federal Housing Finance Agency set parameters for acceptable underwriting criteria by both GSEs, then allow them to offer credit terms within a “clear outer boundary.” “If we are to have a fully functioning secondary market that provides sustainable access to credit for qualified borrowers, then the development of transparent and consistent credit underwriting standards are of the utmost importance,” said the MBA.
