A borrower I recently worked with had a Classic FICO qualifying score of 679. Their VantageScore 4.0 qualifying score, built from the same credit history, was 681. Two points apart. On a $769,000 loan, those two points carried the file across the 680 pricing line and improved the loan's pricing by 0.50 points. The borrower got the exact same interest rate and paid $3,845 less in fees.
Nothing about the borrower changed. They didn't pay anything down or wait for a score to recover. We evaluated their existing credit under a second scoring model that Fannie Mae and Freddie Mac now accept, and that model happened to land on the right side of a pricing tier.
I'm Elliott Bowman, NMLS #1982189, a mortgage broker at Your Mortgage Copilot, powered by Xpert Home Lending, working with 120+ wholesale lending partners across conventional, FHA, VA, jumbo, and non-QM programs. Here's what changed with mortgage credit scores in 2026, why two models can disagree about the same person, and what to ask before you lock a rate.
| Classic FICO | VantageScore 4.0 | |
|---|---|---|
| Qualifying score | 679 | 681 |
| LLPA credit score band | 660–679 | 680–699 |
| Interest rate | Same | Same |
| Pricing | Baseline | 0.50 points better |
| Cost on a $769,000 loan | Baseline | $3,845 less ($769,000 × 0.50%) |
This is an actual result from one client transaction, shown anonymously. It is not a typical or guaranteed outcome. Your scores, pricing tier, and costs depend on your own credit, loan characteristics, lender, and market pricing at the time you lock.
What changed with mortgage credit scores in 2026?
VantageScore 4.0 went from a limited rollout to an option for every lender that sells loans to Fannie Mae and Freddie Mac, and the two agencies now price it the same way as Classic FICO. On April 22, 2026, FHFA announced implementation of VantageScore 4.0 for loans sold to the agencies through an initial group of lenders. On September 9, that was opened to all approved lenders without the need for prior written approval, as outlined in Fannie Mae's Lender Letter LL-2026-06.
The pricing change on September 30 matters most for borrowers. Before it, VantageScore 4.0 loans were priced on separate grids that, as HousingWire reported, effectively marked the score down 20 points. A 681 VantageScore did not price like a 681. Fannie Mae and Freddie Mac removed those separate grids, so loans delivered on or after October 1, 2026 pay the same loan-level fees for the same score band under either model.
Two limits are worth knowing. Lender adoption is optional, so lenders that aren't ready can keep using Classic FICO. And FICO Score 10T, the newer FICO model, is planned for the future but is not yet eligible for delivery to Fannie Mae or Freddie Mac.
What's the difference between FICO and VantageScore 4.0?
They are two different formulas reading the same credit history, so they can produce different scores for the same person. Classic FICO, the model mortgage lending has relied on for decades, largely evaluates where your accounts stand when the report is pulled. VantageScore 4.0 adds 24 months of trended credit data, meaning it looks at the direction of your balances and payments over time rather than a single snapshot. Someone who has been steadily paying down revolving balances can look different under a model that sees the trend.
VantageScore 4.0 can also consider rent, utility, and telecom payment history, but only when that history is actually reported to the credit bureaus. Paying rent on time doesn't automatically count, because many landlords never report it.
In my own practice, I regularly see borrowers whose scores are still held back by an older collection or late payment despite several years of clean history since. Those are the files where a second model is worth checking. To be clear, VantageScore 4.0 doesn't erase derogatory information, and strong recent history doesn't guarantee a higher score. Sometimes the FICO score is the better one.
How did a two-point difference save my client $3,845?
The savings came from crossing a pricing tier boundary, not from the two points themselves. Fannie Mae and Freddie Mac charge loan-level price adjustments, or LLPAs, which are risk-based fees set largely by credit score band and loan-to-value ratio and expressed as a percentage of the loan amount. The credit score bands in Fannie Mae's LLPA Matrix run in 20-point increments, such as 660 to 679 and 680 to 699. A 679 sits in the same band as a 660. A 681 sits in the band above it.
LLPAs reach the borrower in one of two ways: as an upfront cost at closing, often shown as discount points, or built into a higher interest rate when you'd rather not pay the cost upfront. In this transaction the rate stayed the same and the cost came down. Moving from the 660 to 679 band into the 680 to 699 band improved pricing by 0.50 points. One point equals 1% of the loan amount, so on $769,000, half a point is $3,845.
Two points didn't change the borrower. They changed the pricing tier.
Mortgage pricing is set by score band, so where a score lands relative to a band edge matters more than how many points it moved.
The same logic works in reverse. A borrower at 685 under FICO and 690 under VantageScore would gain five points and likely see no pricing change at all, because both scores fall in the same band. How much a band change is worth also varies with loan-to-value and other pricing factors, so the half point in this example won't carry over to every loan.
Why doesn't every lender evaluate both credit scores?
Because using VantageScore 4.0 is optional, and each lender has to build it into its own systems before offering it. Fannie Mae requires the score to be requested from all three credit bureaus, the loan to be underwritten through its automated underwriting system, Desktop Underwriter (DU), and a specific code to be delivered with the loan. Pricing engines, investor relationships, and secondary-market strategy all have to support it too, so adoption has moved at different speeds across the industry.
Some lenders moved quickly. On September 15, UWM, one of the wholesale lenders I work with, reported that about 25% of borrowers coming through its broker partners were seeing a more advantageous credit result with VantageScore 4.0. That figure is UWM's own experience in its own channel, not an industry statistic, and a better credit result doesn't automatically mean lower costs. On October 6, UWM announced it would obtain both FICO and VantageScore 4.0 on all credit pulls and default to the strongest qualifying score. Lender technology is moving quickly, which is good for borrowers. It also means the scoring approach is one more thing that differs from lender to lender.
Why does your mortgage broker's approach matter?
The scoring model is only one variable, and the best result comes from comparing it alongside everything else that affects the cost of the loan. As a broker, I'm not limited to a single lender's rate sheet or a single lender's scoring approach. I can look at which lending partners support VantageScore 4.0, how each prices the resulting score band, how mortgage insurance pricing compares, and how points, lender credits, and rate options stack up across the whole loan.
Sometimes VantageScore 4.0 produces the better outcome. Sometimes FICO does, or a different lender's pricing outweighs the scoring difference entirely. My job is to evaluate the eligible options within agency and lender rules and choose the structure that makes the most financial sense for your goals. Not every lender evaluates the same credit scoring options, and working with someone who understands both models can surface savings that would otherwise go unnoticed.
Elliott can review which eligible credit score models apply to your loan and compare total costs across lenders before you lock.
Will VantageScore 4.0 always save you money?
No. Some borrowers score higher under VantageScore 4.0, some score lower, and many land in the same pricing band either way. A higher score only helps if it moves you into a better band, improves mortgage insurance pricing, or affects eligibility.
The rules also limit how scores can be used. Every borrower on a conventional loan must be evaluated under the same model, so a lender can't use FICO for one co-borrower and VantageScore for another. VantageScore 4.0 must be pulled from all three bureaus, and the qualifying score is then determined under that one model using standard agency rules, typically the middle of the three bureau scores. A lender can't take your best FICO from one bureau and your best VantageScore from another. And for Fannie Mae, VantageScore 4.0 is available only for loans underwritten through DU. Manually underwritten loans must still use Classic FICO, per Fannie Mae's credit score models guidance.
What should homebuyers do now?
Ask your loan officer directly whether both eligible credit score models were evaluated on your file, and which pricing band each one puts you in. Then compare full Loan Estimates rather than interest rates alone. Points, lender credits, mortgage insurance, and total closing costs can vary by thousands of dollars between two offers with the same rate, which is exactly what happened here.
If you're early in the process, run our mortgage calculator for a starting point and see why getting preapproved is the first real step. If you're close to making an offer, that's the right time to have your credit reviewed under both models, since your pricing is set when you lock your rate.
My client didn't change anything about their credit. The same history, viewed through a second eligible model, came out two points higher and $3,845 less expensive. Not every file will see a result like that, but every eligible file deserves the check.
