Short answer

Yes. Since September 9, 2026, all Fannie Mae and Freddie Mac approved lenders may use VantageScore 4.0 instead of Classic FICO on conventional loans, one model per loan. Since October 1, 2026, Fannie Mae and Freddie Mac use aligned pricing for VantageScore 4.0 and Classic FICO, and FHA plans to add it for case numbers assigned starting January 1, 2027. Guidelines may change; all loans subject to credit approval.

For decades, nearly every mortgage in America was underwritten with one family of credit scores: the older “Classic” FICO models. That’s changing. As of September 9, 2026, every lender approved by Fannie Mae and Freddie Mac can use VantageScore 4.0 on conventional loans. Here’s what changed, what didn’t, and what it means for you.

What Changed in 2026

  1. Conventional loans: Lenders can deliver a Fannie Mae or Freddie Mac loan using either Classic FICO or VantageScore 4.0. It used to be a limited rollout. Now it’s open to all approved lenders.
  2. One model per loan: Lenders can’t mix models on the same file. Every borrower on the loan is scored the same way.
  3. Manually underwritten loans still use Classic FICO.
  4. All three credit bureaus are still required (a “tri-merge” report). Proposals to use fewer reports are still being studied.
  5. FICO 10T is approved but not yet eligible for delivery on conventional loans.

Pricing: Aligned With Classic FICO Since October 1, 2026

This is the part most headlines skip. Conventional loan pricing adjustments are set by credit-score brackets. Update (October 2026): Fannie Mae and Freddie Mac now use aligned pricing for VantageScore 4.0 and Classic FICO, effective October 1, 2026. The 20-point bracket offset used when VantageScore 4.0 was first accepted in September no longer applies. Some wholesale lenders also now pull both models and use the higher qualifying score.

Your two scores can still come out as different numbers, and the score used still affects your pricing and mortgage insurance. Because I work with many wholesale lenders, I can compare how your file prices under each model when a lender offers both. Any pricing comparison is an estimate based on the information provided; rates and terms are subject to change.

Where Each Loan Type Stands (September 2026)

  • Conventional (Fannie Mae / Freddie Mac): Classic FICO or VantageScore 4.0, lender’s choice, one model per loan.
  • FHA: Classic FICO today. FHA has announced VantageScore 4.0 and FICO 10T will be added alongside Classic FICO for case numbers assigned starting January 1, 2027.
  • VA: VA doesn’t set a minimum score; lenders set their own requirements.
  • USDA, jumbo and non-QM: Rules vary by program and investor.

Guidelines may change, and lender overlays may be stricter. Not every lender has turned on VantageScore 4.0 yet. Many are still updating their systems.

Some lenders set their own minimums (called overlays) above the program’s rules, and some have recently removed them on agency loans. If one lender told you no, it may not be the final word. See: Credit Score Overlays Explained (2026).

Who Might Benefit

  • Thin-file borrowers. VantageScore 4.0 can score some people Classic FICO can’t, including those with limited or newer credit histories.
  • Borrowers with rent and utility history. The newer model can consider trended data and alternative payment history when it’s reported.
  • Borrowers near a cutoff. Occasionally one model helps a file clear a minimum. It’s worth checking both when a lender allows it.

What It Doesn’t Change

  • The score on your credit card app or Credit Karma still isn’t your mortgage score. See Is Credit Karma accurate for mortgages?
  • Paying on time, keeping card balances low and avoiding new debt before closing still matter most.
  • Income, assets and debt-to-income ratio still decide whether you qualify.

Frequently Asked Questions

Can I get a conventional mortgage with a VantageScore 4.0?

Yes. Since September 9, 2026, all Fannie Mae and Freddie Mac approved lenders may use VantageScore 4.0 instead of Classic FICO, though each lender decides when to adopt it. All borrowers on a loan must be scored with the same model.

Is a VantageScore the same as a FICO score for mortgage pricing?

They are different scores, but since October 1, 2026, Fannie Mae and Freddie Mac use aligned pricing for VantageScore 4.0 and Classic FICO on conventional loans. Your two numbers can still differ, and the score used still affects pricing.

Does FHA accept VantageScore 4.0?

Not yet. FHA has announced it will add VantageScore 4.0 and FICO 10T alongside Classic FICO for case numbers assigned starting January 1, 2027. Guidelines may change.

Do lenders still pull all three credit bureaus?

Yes. Conventional loans still require a tri-merge report from all three bureaus, whichever score model is used.
