Last month federal regulators approved two new mortgage credit scoring models for use by Fannie Mae, Freddie Mac, and the Federal Housing Administration. Regulators approved VantageScore 4.0 and FICO 10T for mortgage lenders.
This is the first change to approved mortgage credit scoring models in decades, and it matters most for buyers who have been underserved by the Classic FICO snapshot approach.
Both new models use trended data, meaning they evaluate how your credit behavior has changed over 24 months rather than capturing a single point-in-time picture. If you've been paying down debt, building a stronger payment history, or paying rent consistently, these models are more likely to reflect that progress.

What changed, and why it matters
For decades, mortgage lenders evaluating loans for sale to the government-sponsored enterprises used only the Classic FICO score. That model measures your credit at a single point in time: how much you owe, whether you've paid on time, and how long you've had credit. It doesn't track direction, so it doesn't show whether your financial situation is improving or deteriorating.
On April 22, 2026, the Federal Housing Finance Agency (FHFA) and the U.S. Department of Housing and Urban Development (HUD) announced that two newer models — VantageScore 4.0 and FICO 10T — are now approved alongside Classic FICO for mortgage underwriting.
Lenders can now choose which approved model to use. Classic FICO isn't going away; it remains a valid option. What's new is that lenders have alternatives, and those alternatives evaluate your credit differently.
This is significant for buyers who have been just out of reach under the old system, particularly those whose credit is trending in the right direction, even if the snapshot doesn't fully capture it.
Classic FICO vs. VantageScore 4.0 vs. FICO 10T at a glance
| Model | What it measures | Key difference | Status |
|---|---|---|---|
| Classic FICO | Snapshot of credit at one point in time | Decades-long standard; no trend data | Still valid; widely used |
| VantageScore 4.0 | 24-month credit trends + on-time rent payment history | Can incorporate rent as a positive credit factor | Active now for approved lenders on conventional loans |
| FICO 10T | 24-month credit trends with trended balance data | Rewards consistent paydown patterns over time | Conventional rollout active; FHA implementation forthcoming |
Model descriptions are based on publicly announced regulatory guidance. Lender adoption varies — not all lenders have access to all models. Ask your lender which credit scoring model applies to your loan.
What trended data means for your credit score
The most important concept in both new models is trended data. It's worth understanding clearly before your next application.
Classic FICO takes a snapshot. If you have $8,000 on a credit card with a $10,000 limit today, your utilization reads as 80%. That's true whether you just ran up the balance last month or have carried it for five years. The model doesn't know or care which scenario applies.
VantageScore 4.0 and FICO 10T look at a 24-month window. They can see whether your $8,000 balance was $12,000 a year ago and is trending down, or whether it was $2,000 18 months ago and has been climbing. Consistently improving patterns are rewarded. Consistently worsening patterns carry more weight as risk signals.
This distinction matters in two practical ways. First, buyers who have been actively paying down debt but haven't yet reached a "good" snapshot number can now get credit for the direction they're moving. Second, buyers who boost their score right before applying, without underlying improvement, may find the trended models less forgiving than they expected.
The implication for anyone preparing to buy: start managing your credit as a trend, not as a one-time sprint before your application date. Understanding what is a credit report and how the data in it gets interpreted is a useful first step.
Who benefits most from the new models
The change isn't universally transformative. For buyers with strong Classic FICO scores, the impact is likely modest. But for certain buyer profiles, the new models represent a meaningful expansion of access.
Renters with strong payment histories. VantageScore 4.0 can incorporate on-time rent payments as a positive credit factor when that data is available through rental reporting services. For buyers who have paid rent reliably for years but have limited traditional credit history, this is a significant shift. It treats responsible financial behavior that Classic FICO ignored as evidence of creditworthiness.
Buyers with thin credit files. If you have only one or two credit accounts and a limited history, Classic FICO often produces a score that doesn't reflect your actual financial discipline. Both new models use broader data patterns and may produce more favorable scores for thin-file applicants. See our guide on how to buy a house with no credit history for more context on this buyer profile.
Borrowers with improving credit trends. If you've been consistently paying down revolving balances over the past 12–24 months, FICO 10T in particular is designed to recognize that pattern. A buyer who went from 75% utilization to 30% over two years looks meaningfully different under FICO 10T than under Classic FICO, which only sees where they are today.
Buyers near qualification thresholds. For FHA loans, the minimum credit score for a mortgage under current guidelines can be as low as 580 with a 3.5% down payment. Buyers who fall just short of conventional qualification thresholds may find one of the new models produces a score that opens additional options.
Self-employed buyers with irregular credit patterns. Seasonal income and variable spending can create credit utilization patterns that look concerning in a snapshot but are entirely normal for that borrower's profile. Trended models have more context to work with.
What this means for your mortgage application right now
The most important practical point: the rollout is staged, not universal. Not every lender is using the new models yet. VantageScore 4.0 is currently available for conventional loans at approved lenders on a limited basis. FICO 10T historical data for the government-sponsored enterprises is expected in summer 2026, with broader lender adoption to follow. FHA is implementing both models on its own timeline, which has not yet been fully published.
What this means for buyers: You cannot assume your application will be scored under the new models just because the announcement has been made. The right move is to ask your lender directly which credit scoring model they're using for your specific loan type.
Beyond that, there are concrete steps worth taking now regardless of which model ultimately applies to your application.
How to prepare for your mortgage application in the next 6–12 months
Manage your credit as a trend, not a snapshot. Both new models evaluate 24-month patterns. Pay down revolving balances consistently over time rather than cramming payoff into the month before your application. Understand what debt to pay off first to raise your credit score and start there.
Enroll in rent reporting if you're a renter. Services that report on-time rent payments to credit bureaus can feed into VantageScore 4.0's rent payment factor. If you're 12–18 months from applying and have been a reliable renter, this is worth setting up now.
Avoid new hard inquiries. Applying for new credit cards or loans before a mortgage application can temporarily lower your score under any model. Know the difference between a soft vs. hard credit check and minimize hard pulls in the 6–12 months before you apply.
Pull your tri-merge report early. Your tri-merge credit report — the combined report from all three bureaus — is what lenders use. Review it for errors well before you apply so you have time to dispute anything inaccurate.
Get pre-approved sooner than you think you need to. Pre-approval under the current underwriting environment tells you exactly what model applies to your loan, what score you're being evaluated on, and what you qualify for. It removes guesswork and gives you time to improve your position if needed. Documents needed for mortgage pre-approval outlines exactly what you'll need to gather.

What hasn't changed
It's worth being clear about what the new models don't affect.
Classic FICO remains a valid, approved model. Many lenders will continue using it, especially during the transition period. If your Classic FICO score is strong, this change is unlikely to affect your application at all.
Your mortgage rate is still determined by your credit score tier, your loan-to-value ratio, your loan size, and the lender you choose and not by which scoring model is used. A higher score produces a better rate regardless of which model generates that score. See current mortgage rates to understand today's rate environment and how your score tier fits into it.
The credit score you see on free monitoring apps uses a VantageScore model, but the version displayed may differ from VantageScore 4.0 as implemented for mortgage use. Don't assume that score is what your lender will see. The only way to know your mortgage-specific score is to go through a lender's pre-approval process.
And finally: how to qualify for a mortgage still comes down to income, debt-to-income ratio, down payment, and credit history. The scoring model is one input into a broader picture that lenders evaluate holistically.
Frequently asked questions
I've been renting for five years and always paid on time — does VantageScore 4.0 mean I can now qualify for a mortgage?
On-time rent payment history can be a positive factor under VantageScore 4.0 when that data is available through rental reporting services. If you've enrolled in a rent reporting service, that payment history may contribute to a higher VantageScore 4.0 than you'd receive under Classic FICO, which doesn't capture rent payments at all. Whether that improvement is enough to qualify depends on your full credit profile, income, and the loan type you're applying for. Getting pre-approved is the fastest way to find out where you stand.
What's the difference between FICO 10T and VantageScore 4.0, and which one will my lender use?
Both use 24-month trended data, but they weight factors differently. FICO 10T focuses heavily on how your balances have moved over time, rewarding consistent paydown patterns. VantageScore 4.0 can incorporate rent payment history and may score thin-file borrowers more favorably. Which model your lender uses depends on their approval status and the loan type. Ask your lender directly, "Which credit scoring model are you using for this loan?" This is a straightforward question every lender should be able to answer.
My credit score is 640 under Classic FICO. Could the new models help me qualify for an FHA loan?
Possibly. If your score reflects a snapshot that doesn't capture an improving trend, a trended model may produce a higher score. However, FHA's full implementation timeline for VantageScore 4.0 and FICO 10T hasn't been published yet. The best step is to apply for pre-approval and ask your lender explicitly which model applies to FHA loans in your scenario.
Are all mortgage lenders using the new models now?
No. The rollout is staged. VantageScore 4.0 is currently available for conventional loans at a limited set of approved lenders. FICO 10T historical data for the government-sponsored enterprises is expected in summer 2026 ahead of broader adoption. FHA's timeline is separate and pending. Many lenders will continue using Classic FICO during the transition. Confirm with your lender which model applies to your application.
Will my credit score from a free monitoring app now match what mortgage lenders see?
Not necessarily. Free monitoring apps use a VantageScore model, but the version may differ from VantageScore 4.0 as implemented for mortgage underwriting. The score in a free app is a useful general indicator but isn't the mortgage-specific score lenders will pull. The only reliable way to know your mortgage qualification picture is through a lender's formal pre-approval process.
I paid off most of my credit card debt over the past two years — will FICO 10T give me a better score?
Likely yes, if the paydown is reflected consistently over those 24 months. FICO 10T is specifically designed to reward the kind of sustained balance reduction you're describing. Buyers who made large lump-sum payoffs right before applying may see less benefit than those who reduced balances gradually over time.
What should I do now to prepare my credit for the new models?
Focus on consistency over 24 months: pay down revolving balances steadily rather than all at once, avoid new hard inquiries, enroll in rent reporting if you're renting, and pull your tri-merge report early to fix any errors. Understand what debt to pay off first to raise your credit score and start there. The new models reward the kind of financial behavior you should be building toward anyway.
Does the change affect refinance applications, or only purchases?
The new models apply to mortgage originations broadly for loans sold to the government-sponsored enterprises or insured by the FHA. If you're considering a refinance, the same principles apply: ask your lender which model they're using and review your credit trends before applying.
