GSEs broaden VantageScore 4.0 access to all lenders
Fannie Mae and Freddie Mac now accept VantageScore 4.0 for all lenders, alongside Classic FICO. Lenders must use the same model for all borrowers on a loan. Fannie and Freddie updated pricing guidelines for VantageScore 4.0. Rocket Mortgage and United Wholesale Mortgage lead in VantageScore 4.0 adoption, with 30% and 25.3% of their GSE loans using it, respectively. KBW notes limited industry-wide adoption.

Market read

Limited short‑term price movement for FMCC.
Similar to FNMA, the change is procedural with modest market impact.
Rocket Mortgage increased its VantageScore 4.0 share of GSE production to 30% in August.

Higher VS4 usage signals competitive advantage in pricing flexibility.
Market effects
