VantageScore 4.0 and FICO 10T in 2026: What Fannie, Freddie, and FHA Allow Today

Credit scoring models for mortgages are changing in 2026. Mortgage professionals need a clear read on VantageScore 4.0 and FICO Score 10T, plus what still runs on Classic FICO, based on the latest updates to the Fannie Mae Selling Guide and Freddie Mac Seller/Servicer Guide. FHA has signaled its own modernization path through INFO 2026-11, though specific FHA implementation details remain pending.

What are the current allowances for VantageScore 4.0 and FICO Score 10T?

As of 2026, both Fannie Mae and Freddie Mac have approved the use of VantageScore 4.0 for mortgage underwriting. According to the Fannie Mae Selling Guide, lenders can use Equifax, Experian, and TransUnion versions of VantageScore 4.0. Similarly, Freddie Mac's Single-Family Seller/Servicer Guide confirms the eligibility of these versions for approved sellers. However, the implementation of FICO Score 10T is still in progress. Fannie Mae is working towards integrating FICO Score 10T, while Freddie Mac plans to purchase mortgages using this score once their updated framework is complete.

For now, lenders interested in using VantageScore 4.0 should contact their respective Fannie Mae or Freddie Mac representatives for program availability and eligibility requirements. The transition to these modernized scoring models is part of an effort to enhance credit score accuracy and competitiveness.

How do Classic FICO scores fit into the current framework?

Despite the shift towards newer models, Classic FICO scores remain a staple in mortgage underwriting. Both Fannie Mae and Freddie Mac continue to require Classic FICO scores for loans underwritten through their systems. Specifically, Fannie Mae mandates the use of Equifax Beacon 5.0, Experian/Fair Isaac Risk Model V2, and TransUnion FICO Risk Score, Classic 04. Freddie Mac follows a similar approach, utilizing Equifax FICO Classic v5, Experian/Fair Isaac Risk Model v2, and TransUnion FICO Risk Score 04.

These Classic FICO scores are essential for determining underwriting scores and indicator scores, which are crucial for assessing borrower creditworthiness and mortgage eligibility. The continued use of these scores ensures consistency and reliability during the transition to newer models.

What are the pending implementation dates for VantageScore 4.0 and FICO Score 10T?

The implementation of VantageScore 4.0 is already underway, with both Fannie Mae and Freddie Mac allowing its use for approved lenders. However, the full integration of FICO Score 10T is still pending. Fannie Mae has indicated that they are working to implement FICO Score 10T in a timely manner, but specific dates have not been finalized. Freddie Mac, on the other hand, has not yet made mortgages delivered with FICO Score 10T eligible, pending further progress on their updated credit score framework.

Mortgage professionals should stay in close contact with their agency representatives to receive the latest updates on implementation timelines. This proactive approach will ensure that they are prepared to adapt to the new scoring models as they become fully operational.
