Fannie Mae and Freddie Mac are moving forward with the adoption of VantageScore 4.0 for mortgage originations, a significant shift expected to broaden access to homeownership and introduce greater competition in the credit scoring market. The Federal Housing Finance Agency (FHFA) initially mandated acceptance of VantageScore 4.0 in July 2025, with Fannie Mae announcing on April 22, 2026, updates to its Selling Guide to allow immediate use by approved lenders. This development marks a departure from the decades-long reliance on FICO scores, with social media commentary highlighting the new model's cost efficiency. > "Fannie and Freddie would be using a VantageScore 4.0 mortgage origination score that is cheaper than FICO’s offering," noted Jevgenijs Kazanins on social media.
The adoption of VantageScore 4.0 is anticipated to reduce lending costs and foster a more competitive environment. Industry analysis suggests that introducing competition between scoring models could cut credit report and scoring expenses by over $100 per loan for lenders. This competitive pressure has already led credit bureaus to significantly reduce the cost of VantageScore 4.0, with some offerings priced as low as $1 per score. This move aims to break FICO's historical dominance in the mortgage underwriting process.
A primary benefit of VantageScore 4.0 lies in its ability to score a wider range of individuals, potentially including 33 million more people than traditional models. By incorporating alternative data such as rent and utility payments, the model offers a more comprehensive assessment of creditworthiness. This inclusivity is projected to enable an estimated five million additional Americans, including veterans and those with thin credit files, to qualify for homeownership. The FHFA believes this modernization could unlock up to $1 trillion in incremental high-quality mortgage activity.
This shift aligns with the 2018 Credit Score Competition Act, which aimed to modernize credit scoring models for loans sold to the government-sponsored enterprises. While Fannie Mae has allowed immediate use for approved lenders, the broader industry transition, including system updates and integration, is expected to continue through 2026. The FHFA has also validated FICO Score 10T for future use, signaling a move towards a multi-score underwriting environment rather than a complete replacement of FICO. This phased approach ensures operational readiness across the mortgage industry.
