Fair Isaac's Dominance in Mortgage Credit Scoring Could be Challenged by New Grid Structure, BofA Says in Downgrade

Fannie Mae, Freddie Mac Align Credit-Score Pricing

Fannie Mae said Sept. 30 that loan-level price adjustments, or LLPAs, are now aligned across Classic FICO and VantageScore 4.0. The revised pricing applies to whole loans purchased on or after Oct. 1 and to loans delivered into mortgage-backed securities with issue dates on or after Oct. 1.

Freddie Mac separately confirmed that credit fees for the two models have been aligned to simplify pricing and provide sellers with greater consistency.

The distinction matters because the pricing grid determines how characteristics such as a borrower's credit score and loan-to-value ratio affect the price a lender receives when selling a mortgage to a GSE.

BofA's analysis, as reported by MT Newswires, said the new structure removes a previous 20-point adjustment for VantageScore that was intended to account for differences in how the two models produce scores.

The result is a more direct comparison between the competing models from a mortgage-pricing perspective.

VantageScore's Mortgage Role Is Expanding

The pricing change follows a broader series of moves by the Federal Housing Finance Agency and the GSEs to modernize mortgage credit scoring.

FHFA said in September that VantageScore 4.0 became broadly available to all Fannie Mae- and Freddie Mac-approved lenders for eligible loans, eliminating the previous requirement for prior written approval.

Freddie Mac said VantageScore 4.0 can now be used by all sellers when originating and selling eligible mortgages to the GSE.

Fannie Mae likewise expanded VantageScore 4.0 from a limited lender rollout to broad availability earlier in September.

The broader framework also contemplates FICO Score 10T. Fannie Mae and Freddie Mac have identified Classic FICO, VantageScore 4.0 and FICO 10T as approved models, although FICO 10T has not yet reached the same implementation stage as VantageScore 4.0.

That means the competitive landscape is changing on multiple fronts rather than through a single replacement of FICO.

Why the Change Matters to Fair Isaac

Fair Isaac has built a substantial business around credit scoring, including mortgage-originations scoring.

In its most recent reported quarter, ended June 30, FICO said scores revenue increased 41% year over year to $458.9 million. Business-to-business scores revenue increased 49%, with the company attributing the increase in part to a higher mortgage-origination score unit price.

FICO reported total third-quarter revenue of $674.2 million, up 26% from the prior-year quarter, and raised its fiscal 2026 revenue guidance to $2.53 billion from $2.45 billion.

Those results illustrate why changes to mortgage scoring can matter to investors even while the company's broader business continues to grow.

BofA's concern, according to the reported downgrade, is that the new pricing structure creates additional risk to FICO's score volumes, pricing power and mortgage-market share. The brokerage also pointed to continued regulatory scrutiny as a potential constraint on future score-price increases.

The assessment is an analyst view rather than a determination that FICO will lose its mortgage position.

Rocket Mortgage Adds Another Competitive Signal

The GSE changes have already been followed by a major lender decision.

Rocket Mortgage announced Sept. 28 that it will make VantageScore 4.0 its preferred credit-scoring model for eligible mortgages beginning in the fourth quarter. The company said it reached the decision after roughly four months of testing involving both VantageScore and FICO.

Rocket said it had obtained 1.4 million credit reports using both models during 2026 and found that VantageScore helped more clients meet credit requirements and reduced credit-scoring costs. The company said borrowers who saved money using VantageScore saw an average savings of $1,600 at closing. Those figures are Rocket's own reported results and have not been independently verified.

The lender's transition will not cover every mortgage product. Rocket said investment-property and second-home mortgages, home-equity loans, FHA loans, jumbo loans and certain other products will continue to use FICO for now. Its Rocket Pro broker channel will provide both VantageScore and FICO, preserving model choice for mortgage brokers.

That distinction is important: the emergence of VantageScore does not mean FICO has disappeared from mortgage lending.

What Changes for Mortgage Lenders

For lenders, the immediate issue is operational as well as economic.

Fannie Mae and Freddie Mac are allowing VantageScore 4.0 broadly, but lenders still have to integrate the model into their credit, underwriting, pricing and delivery processes. Freddie Mac has described the transition as part of a measured effort to establish a modernized and competitive credit-score framework while maintaining risk-management and operational controls.

The aligned pricing grids could reduce one source of complexity by applying consistent LLPA treatment across Classic FICO and VantageScore 4.0.

It also gives lenders greater practical flexibility in deciding which approved model fits their operations and borrower base.

For consumers, however, the existence of another approved score does not automatically mean every borrower will receive a lower mortgage rate or qualify for a loan. Mortgage underwriting continues to consider income, debt, assets, property characteristics and other requirements in addition to credit scores.

A Challenge to FICO, Not an Immediate Replacement

The latest developments represent a significant change in the mortgage credit-scoring structure, but they do not establish that FICO has lost its position in the market.

FICO's own filings say its score is used by 90% of top U.S. lenders, underscoring the scale of its existing position.

The more immediate question is whether lenders will increasingly choose VantageScore when both models receive equivalent pricing treatment — and whether that choice changes the volume of FICO scores ordered for mortgage transactions.

BofA's downgrade reflects the possibility that the answer could materially affect Fair Isaac's mortgage-related pricing, volume and market share. At the same time, FICO remains an approved mortgage credit-score model, and the GSE transition includes FICO Score 10T as another model slated for future use.

For the mortgage industry, Oct. 1 marks less a clean break with FICO than the beginning of a more competitive scoring environment. The next major indicator will be how broadly lenders adopt VantageScore 4.0 now that the model has broad GSE availability and its pricing treatment has been aligned with Classic FICO.
