In September 2026, Bank of America researchers published findings that internal GSE credit scores provide a more accurate prediction of mortgage delinquency than traditional measures. The study evaluated how these scores track risk over a 24-month performance period.
Why it matters
GSE scores incorporate alternative data to meet legal mandates, helping to mitigate industry concerns regarding the reliability of mortgage performance systems. These internal metrics allow for more precise risk assessment by using automated underwriting processes.
Fannie Mae scores range from 400 to 950, while Freddie Mac scores span 200 to 1,000. These internal scores consistently trend 10 to 30 points higher than traditional FICO or VantageScore 4.0 measurements.
The players
Bank of America

Freddie Mac
This is a government-sponsored enterprise that operates in the secondary mortgage market to support homeownership.

The details
The analysis revealed that GSEs require VantageScore 4.0 loans to hold scores approximately 20 points higher than standard FICO measures to achieve equivalent pricing. These internal scores are generated by automated systems and focus on predicting delinquency risk thresholds exceeding 90 days.
Timeline
September 2026 was when the new score metrics were released by oversight agencies.
Roadmap
The shift toward internal GSE scoring reflects a broader transition away from a single reliance on traditional credit reporting agencies. This evolution signals a fundamental change in how the secondary mortgage market assesses borrower risk and pricing.
Homebuyers may notice that different scoring models result in varying loan eligibility requirements or interest rate pricing. Understanding these internal metrics is essential for navigating the current automated underwriting landscape when applying for a mortgage.
The takeaway
GSE internal scores now provide a primary benchmark for assessing mortgage risk beyond traditional credit reports. Borrowers should remain aware that mortgage pricing now relies on these complex, alternative-data-informed metrics.
