VantageScore 4.0 vs FICO for Your 2026 Mortgage

VantageScore 4.0 vs FICO for Your 2026 Mortgage

Updated 12 September 2026. Both models are now live options on a conventional mortgage. FHFA confirmed on 9 September 2026 that all Fannie Mae and Freddie Mac approved lenders may use VantageScore 4.0, with no prior written approval, and that the lender picks Classic FICO or VantageScore 4.0 on each loan it delivers. For the full news explainer, read what the 9 September 2026 FHFA change means for your mortgage.

That replaces the position this page described in July, when VantageScore 4.0 was confined to a limited rollout that began 22 April 2026. The gate is gone. Classic FICO also remains approved, with no retirement date announced, so the practical question is no longer “when” but “which one is my lender pulling.”

Here is where the two models really diverge, who each one favors, and what to do about it.

Where the two models split

On the surface both run 300 to 850. Underneath, they read your file differently.

VantageScore 4.0 uses trended data, looking at 24 months of your balances instead of a snapshot. It can fold in rent, utility, and telecom payments when those are reported. And it can score a credit file with as little as one month of history. Classic FICO, meaning the older FICO 2, 4, and 5 versions mortgage lenders use, does none of that. It needs about six months of history, ignores rent unless it appears as a normal tradeline, and runs stricter on collections.

The table lines those differences up. The practical result is that the same person can score meaningfully differently on the two models, sometimes by 20 to 60 points.

Who each model favors

This is not a case of one score being higher for everyone. It cuts both ways, and pretending otherwise would set you up for a surprise.

VantageScore 4.0 tends to help thin-file borrowers, people with paid collections, and renters whose payments get reported, because it counts data the old FICO throws away. But its trended data can work against you if your balances are climbing month over month, since it sees the direction, not just the current number. Classic FICO ignores that trend entirely. So there is no universal winner. The right question is not “which is higher” but “which one is my lender using, and what does my specific file look like on it.” We map the mortgage models in full in what credit score mortgage lenders use.

What changed in July 2026

The concrete 2026 milestone: on July 1, Fannie Mae and Freddie Mac released historical data for both FICO 10T and VantageScore 4.0.

That release lets lenders and investors study how the newer models would have performed on real loans before committing. Tri-merge credit reports are also staying, and FHFA states the addition of VantageScore 4.0 does not change the current credit reporting requirements. For the bureau-count debate, see bi-merge vs tri-merge credit reports.

What changed on 9 September 2026

The limited rollout ended. FHFA’s credit scores page, last updated 9 September 2026, states that the Enterprises “expanded the availability of VantageScore 4.0 to all approved lenders, removing the requirement for prior written approval.”

Three things did not change on that date, and each is worth knowing before you apply. Tri-merge credit reporting stays as it is. Classic FICO stays approved with no announced retirement date. FICO Score 10T, validated alongside VantageScore 4.0 on 24 October 2022, is still not eligible for delivery to Fannie Mae or Freddie Mac. One more rule applies to couples: a lender may pick a different model on the next loan, but must use the same model for every borrower on the same loan.

What to do while it is in flux

You cannot control which model your lender picks, but you can ask which one it will pull before the hard inquiry lands. You can also control the report both models read, and the habits that lift both scores.

Pay on time, keep utilization low across months, and get your reports clean. Pull all three at AnnualCreditReport.com and remove errors, since a wrong late mark or a paid collection still showing a balance drags every model down. If your rent is not being reported and you have a clean payment record, getting it reported can only help under VantageScore 4.0.

You can manage all of that by hand. Or Credit Booster AI reads all three reports, flags the errors costing you points on either model, drafts the removal letters, and tracks your progress toward a home loan. Free to download on iOS and Android, with plans from $9.99 and a 7-day free trial on Plus. Cleaning up genuine mistakes is where most buyers find 30 to 60 points, and it pays off whichever model your lender pulls.
