Useful takeaways from this story.

Ishbia described concrete borrower benefits: improved LLPAs and lower mortgage insurance costs after a borrower’s VantageScore moved a pricing bucket.

FHFA now allows approved GSE lenders to choose between VantageScore 4.0 and Classic FICO for conventional loans.

At the AIME Fuse conference in Austin, United Wholesale Mortgage (UWM) CEO Mat Ishbia said VantageScore 4.0 is already helping more borrowers qualify and improve loan pricing. His remarks followed FHFA's move to permit approved single-family lenders doing conventional business through Fannie Mae and Freddie Mac to choose between VantageScore 4.0 and Classic FICO.

UWM says roughly one in four of its borrowers is seeing a more advantageous result with VantageScore 4.0 compared with Classic FICO. The company expects that share could reach about 40% by the end of September. UWM highlights three types of outcome changes tied to the new model: loan-level price adjustments (LLPAs) that fall into lower buckets, lower mortgage insurance costs, and expanded eligibility that can turn a decline into an approval.

Ishbia shared a broker case: a borrower initially had a 733 FICO score on preapproval. When the file moved toward contract, the broker pulled UWM's free credit report and obtained a VantageScore of 775, which was reduced to 755 after a mandatory 20-point adjustment. That higher score moved the loan into a lower LLPA bucket, reduced mortgage insurance by more than $100 a month, and improved pricing by three-eighths of a percent in Ishbia's description.

Industry reaction and competing analysis

Operational changes at UWM: Underwriter+

Why it matters for brokers and borrowers

For brokers: having both score models available increases options for qualifying borrowers and improving pricing in some cases. UWM chose to allow brokers to pick which credit model to use in the mortgage process rather than defaulting to one model.

For borrowers: the practical effects, per UWM's examples, include the possibility of better pricing buckets and lower mortgage insurance expenses when VantageScore produces a higher result. Analysts and other lenders caution that outcomes will vary by borrower and model choice.

FHFA's decision opened VantageScore 4.0 to approved GSE lenders, and FHA is expected to offer VS4.0 and FICO 10T for FHA loans in January, according to reporting cited by UWM. Pricing and delivery rules remain subject to further discussion between regulators and model providers.

UWM is publicly backing VantageScore 4.0 based on early borrower outcomes and broker feedback, and it is running an operational change—Underwriter+—that it says speeds closing and reduces file touches. Other market participants and analysts warn outcomes will differ across borrowers and lenders, making model choice and implementation important operational decisions.
