The U.S. mortgage industry is moving another step closer to modernizing the way credit risk is evaluated. Fannie Mae and Freddie Mac have released expanded historical loan-level data that allows lenders, investors, and other housing finance professionals to independently evaluate the performance of FICO Score 10T, one of the newest credit scoring models designed for mortgage lending.
The release provides years of real mortgage performance data and represents another milestone in the transition from older credit scoring models toward more advanced methods that better reflect today’s borrowers and lending environment.
Industry participants now have access to the information needed to validate how FICO Score 10T performs across a wide range of mortgage loans before broader adoption throughout the housing finance system.
Historical Loan Data Now Available
The newly released datasets include loan-level mortgage performance information covering the period from April 2013 through September 2025.
By making this information publicly available through Fannie Mae and Freddie Mac, lenders and housing finance professionals can analyze how loans performed over time using the FICO Score 10T model.
Rather than relying solely on internal testing or theoretical projections, market participants can now review actual mortgage performance across more than a decade of lending activity.
This additional transparency is expected to help lenders better understand how the updated scoring model evaluates borrower risk under different economic conditions.
What Is FICO Score 10T?
FICO Score 10T is a newer generation of credit scoring designed to provide a more complete picture of a consumer’s financial behavior.
Unlike older credit scoring models that rely primarily on a snapshot of current credit information, FICO Score 10T incorporates trended credit data, allowing lenders to see how borrowers have managed their credit over time.
Instead of looking only at current balances and payment history, the model evaluates long-term patterns, including whether borrowers consistently reduce debt, maintain stable balances, or gradually increase their borrowing.
These additional insights may improve lenders’ ability to assess repayment risk more accurately.
Rental Payment History Can Strengthen Credit Evaluation
Another important feature of FICO Score 10T is its ability to incorporate rental payment history, when that information is available through a consumer’s credit file.
For many first-time homebuyers, renters, and individuals with limited traditional credit histories, consistent rent payments can provide valuable evidence of responsible financial behavior.
Including rental payment data may help some borrowers demonstrate creditworthiness even if they have relatively limited experience with traditional forms of borrowing.
As more rental payment information becomes available through credit reporting systems, this feature could expand access to mortgage financing for qualified applicants.
Why Credit Score Modernization Matters
Mortgage underwriting has traditionally relied on older credit scoring models that were introduced many years ago.
However, consumer borrowing habits have changed significantly over the past decade.
Today’s borrowers often have more diverse financial profiles that include:
- Digital banking
- Online lending
- Buy now, pay later services
- Gig economy income
- Self-employment
- Alternative payment histories
- Different patterns of credit usage
Modern credit scoring models are designed to better reflect these evolving financial behaviors while improving the accuracy of risk assessment.
Supporters of credit score modernization believe that more predictive models can benefit both borrowers and lenders by improving underwriting decisions without reducing lending standards.
Benefits for Lenders
The expanded historical data allows mortgage lenders to perform their own independent analysis before adopting the updated scoring model.
Using real loan performance data, lenders can:
- Compare FICO Score 10T with older scoring models.
- Evaluate default and repayment trends.
- Test underwriting strategies.
- Improve risk management.
- Refine loan pricing decisions.
- Better understand borrower performance over time.
Access to independent validation data gives financial institutions greater confidence when evaluating potential changes to underwriting guidelines.
Benefits for Borrowers
While the transition primarily focuses on improving lender decision-making, borrowers could also benefit from more accurate credit evaluations.
Modern scoring models may help identify applicants whose financial strength is not fully reflected under older scoring systems.
Potential advantages include:
- More accurate credit assessments
- Better recognition of long-term responsible credit behavior
- Consideration of eligible rental payment history
- Expanded access for borrowers with nontraditional credit profiles
- Improved opportunities for first-time homebuyers
Although individual mortgage approval will continue to depend on factors such as income, assets, debt-to-income ratio, and property qualifications, a more comprehensive credit score may improve financing opportunities for some applicants.
Independent Validation Encourages Industry Confidence
One of the most significant aspects of this release is that lenders are not being asked to simply trust the updated model.
Instead, Fannie Mae and Freddie Mac have provided historical mortgage data that allows market participants to conduct their own evaluations.
This independent validation process supports greater transparency throughout the mortgage industry.
Banks, mortgage companies, investors, and secondary market participants can analyze the information using their own models and risk management practices before making implementation decisions.
Free Access Program Expands Availability
To encourage broader evaluation, FICO has also made FICO Score 10T available through its Free Access Program.
The program allows participating lenders to compare the new scoring model with the traditional Classic FICO score at no cost.
According to FICO, nearly 70 lenders have already enrolled in the program, reflecting growing industry interest in modern credit scoring.
The initiative is expected to help accelerate testing and familiarization before wider implementation across the mortgage market.
The Future of Mortgage Credit Scoring
The release of historical loan-level data represents another important step in the mortgage industry’s broader effort to modernize underwriting standards.
As lending technology continues to evolve, credit evaluation is expected to incorporate a wider range of financial information while maintaining strong risk management practices.
Future underwriting systems may increasingly combine:
- Advanced credit scoring models
- Trended credit analysis
- Automated income verification
- Artificial intelligence
- Alternative financial data
- Digital document processing
These tools are intended to improve efficiency while helping lenders identify qualified borrowers more accurately.
Looking Ahead
The availability of expanded historical loan-level data gives the mortgage industry a valuable opportunity to evaluate one of its newest credit scoring models using real-world lending performance.
As lenders continue testing FICO Score 10T, the industry will gain a clearer understanding of how modern credit scoring can improve mortgage underwriting while maintaining prudent lending standards.
For borrowers, particularly first-time buyers and those with strong long-term financial habits, credit score modernization may gradually create a more complete and balanced picture of creditworthiness.
As the housing finance system continues to evolve, initiatives like this are expected to play an important role in making mortgage lending more accurate, efficient, and responsive to today’s changing borrower profiles.
