A Credit-Score Shift at Fannie and Freddie Is Shaking Up the Mortgage Market

Regulators and lenders are now allowing VantageScore, a metric by Equifax, Experian, and TransUnion, for mortgage underwriting, challenging FICO's dominance. The FHFA, overseeing Fannie Mae and Freddie Mac, aims to lower mortgage costs and increase affordability. Fair Isaac's stock has fallen about 60% this year. Lenders like Rocket Mortgage and United Wholesale Mortgage are adopting VantageScore, potentially affecting mortgage rates and market dynamics.
