For decades, getting a mortgage meant one thing: your FICO Classic score determined everything. That is changing. In 2026, the Federal Housing Finance Agency (FHFA) and the Department of Housing and Urban Development (HUD) began allowing two new credit scoring models for mortgage underwriting: VantageScore 4.0 and FICO 10T. For millions of Americans — especially first-time buyers and people with thin credit files — this shift could make the difference between qualifying for a home loan and being turned away.
Here is what the change means, who benefits, and what to do about it before you apply for a mortgage.
What Changed and When
Fannie Mae and Freddie Mac, the two government-backed mortgage giants that back most U.S. home loans, launched a pilot program allowing lenders to use VantageScore 4.0 exclusively for loans delivered to them. FHFA Director Bill Pulte announced the change alongside a new pricing grid that reflects the updated scoring models. HUD Secretary Scott Turner separately announced that FHA-insured mortgages would now permit both VantageScore 4.0 and FICO 10T as eligible scoring models for underwriting.
This is a limited rollout to approved lenders first, not an immediate industry-wide change. However, it signals a clear direction: the traditional FICO Classic score is no longer the only path to homeownership in the U.S.
Why VantageScore 4.0 and FICO 10T Are Different
The old FICO Classic model, which has dominated mortgage lending since the 1990s, only looks at traditional credit data: credit cards, auto loans, student loans, and other debt reported to the three major bureaus. It ignores rent payments, utility bills, and phone payments entirely, even though these are often the largest recurring obligations a renter has.
VantageScore 4.0
VantageScore 4.0 incorporates trended credit data, meaning it does not just look at your balances today — it looks at whether your balances are going up or down over time. A borrower who has been paying down debt steadily looks very different under this model than someone who has been accumulating it, even if their current balances are similar.
VantageScore 4.0 also scores more people. It can generate a score for consumers with as little as one month of credit history and one account reported in the past 24 months. FICO Classic requires at least six months of history. This means millions of Americans who are currently “unscorable” under the old model can now get a score.
FICO 10T
FICO 10T (the T stands for trended data) similarly incorporates 24 months of payment history patterns rather than just a snapshot. It weighs recent behavior more heavily than older behavior, which benefits borrowers who have cleaned up their finances in the last two years even if they had problems before that.
Both models are designed to be more predictive of actual loan default risk than the classic model, which is why lenders and regulators have pushed for the change.
Who Benefits Most
Renters with strong payment histories
If you have paid your rent on time for years but have a limited credit card and loan history, VantageScore 4.0 can potentially give you a higher score than FICO Classic. Rent payment history is one of the strongest signals of financial reliability, and the new models are better at capturing it when it has been reported to the bureaus.
One action to take now: sign up for a rent reporting service such as Experian RentBureau, Rental Kharma, or RentTrack. These services report your rent payments to the credit bureaus so the new scoring models can see them. This costs between $0 and $10 per month depending on the service.
Thin file borrowers
Young adults, recent immigrants, and people who have historically avoided debt often have thin credit files — enough history to exist in the bureau system but not enough for FICO Classic to generate a reliable score. VantageScore 4.0 can score these borrowers with less history, potentially opening mortgage access to people who were previously invisible to the system.
People who paid down debt in the last two years
If you carried high balances two years ago but have been aggressively paying them down, the trended data models capture your trajectory, not just your endpoint. Under FICO Classic, two borrowers with identical current balances look the same. Under FICO 10T and VantageScore 4.0, the one who paid down from $15,000 to $3,000 looks significantly better than the one who added debt to reach the same $3,000 balance.
Who It Does Not Help (Yet)
The rollout is limited. Not every lender participates in the pilot program, and conventional loans backed by Fannie Mae and Freddie Mac are rolling out the change gradually through approved lenders first. If you apply for a mortgage with a lender that has not yet adopted the new models, your application will still be evaluated on FICO Classic.
The new models also do not eliminate the other factors that determine mortgage approval: debt-to-income ratio, down payment size, employment history, and the property itself. A better credit score helps, but it does not override a 50% debt-to-income ratio or a 3% down payment on a jumbo loan.
What This Means for Your Credit Score Number
Your VantageScore 4.0 and your FICO Classic score may be different numbers. Do not assume one is wrong. They are calculated differently and measure slightly different things. A borrower could have a 680 FICO Classic and a 710 VantageScore 4.0, or vice versa.
For mortgage shopping purposes, ask lenders specifically which model they are using. Once the new models are widely adopted, shopping your score under both FICO 10T and VantageScore 4.0 will give you a more complete picture of where you stand.
You can check your VantageScore 4.0 for free through Credit Karma, which uses VantageScore as its primary model. FICO 10T is newer and not yet as widely available for free consumer access, but some lenders will pull it during the pre-qualification process.
Action Steps Before You Apply for a Mortgage
- Sign up for rent reporting if you are a renter with a strong payment history. Services like Experian RentBureau can add months or years of on-time rent payments to your credit file, boosting your VantageScore 4.0.
- Check your VantageScore 4.0 through Credit Karma or your bank’s free credit score tool. Compare it to your FICO Classic score from myFICO.com.
- Ask your lender which scoring model they are currently using. If they are still on FICO Classic and you believe VantageScore 4.0 would show you more favorably, ask if they participate in the Fannie Mae or Freddie Mac pilot or offer FHA loans under the new HUD guidelines.
- Pay down revolving balances over the next 6 to 12 months. The trended data in FICO 10T and VantageScore 4.0 rewards declining balances more explicitly than FICO Classic.
- Do not open new accounts in the 6 months before applying. New accounts lower the average age of your credit and trigger hard inquiries. Both new models still count these negatively.
The Bigger Picture
This change is part of a longer push to make mortgage lending more accessible to first-time and underserved buyers without compromising loan quality. The data suggests VantageScore 4.0 and FICO 10T are more predictive of default risk than FICO Classic, meaning lenders can actually make better decisions — not just more lenient ones — with the new models.
For millennials and Gen Z buyers who have strong rent payment histories, limited traditional credit, and are trying to break into homeownership in a difficult market, this shift is one of the more meaningful structural changes in years. It will not make a $500,000 home affordable on a $60,000 salary, but it may remove a credit score barrier that was previously blocking the path entirely.
