Fannie and Freddie’s Embrace of FICO Rival Raises Questions Over Mortgage Costs and Risk
Fannie Mae and Freddie Mac are adopting VantageScore 4.0, challenging FICO's dominance in mortgage credit scoring. The FHFA says this will reduce costs and expand access, but analysts warn of potential risks. FICO's parent, Fair Isaac, has seen its shares drop 60% this year. Major lenders like Rocket Mortgage and United Wholesale Mortgage are already using VantageScore, with nearly $4 billion in loans originated using it in August.
