Credit scoring is undergoing major modernization in 2026 as mortgage lenders gain access to new models that evaluate borrower creditworthiness more comprehensively. On April 22, 2026, Fannie Mae announced it would allow approved lenders to use VantageScore 4.0 immediately and plan for future adoption of FICO Score 10T, marking a significant shift away from decades of reliance on the Classic FICO model.
The Federal Housing Finance Agency (FHFA), along with Fannie Mae and Freddie Mac, has been leading a multi-year credit score modernization initiative. Both VantageScore 4.0 and FICO 10T were validated and approved by FHFA in October 2022 after rigorous testing. These new models take into account additional sources of data, including rent payment history, to more accurately assess credit risk, according to the FHFA.
The shift addresses a long-standing limitation of traditional credit scoring: the inability to capture payment behavior outside traditional lending. VantageScore 4.0 places greater emphasis on alternative payment history, including rent and utility payments. This expansion of data sources has the potential to significantly broaden access to mortgage lending. Research from VantageScore shows that adding a history of on-time rental payments improves predictive performance by 11 percent.
The practical impact for consumers could be substantial. According to Equifax data, VantageScore 4.0 could help qualify 10 percent more borrowers by providing enriched data like rental history and trended credit data. A separate analysis found that VantageScore 4.0 could reduce mortgage costs by nearly $1 billion through enhanced competition among scoring models.
Fannie Mae is implementing these changes through a limited rollout to approved lenders to ensure operational readiness before broader availability. Approved lenders may now use VantageScore 4.0 from each credit bureau through a tri-merge credit report for originating and delivering new loans. Lenders not yet approved must continue using Classic FICO scores until VantageScore 4.0 is made broadly available. The enterprises expect to publish historical FICO 10T scores in summer 2026 to support the eventual transition to that model.
The new models analyze account activity over 24 months and recognize when borrowers make more than minimum payments, signaling good financial management. This deeper analysis creates opportunities for individuals with limited traditional credit histories—renters, recent immigrants, and others with thin credit files—to demonstrate creditworthiness and access homeownership.
Jake Williamson, Executive Vice President and Head of Single-Family at Fannie Mae, stated that “credit score model modernization is an important step toward a more competitive, innovative, and resilient housing finance system.” By incorporating newer models with more predictive power, the enterprises aim to support sustainable access to homeownership while maintaining safety and soundness.
