Can You Use Your VantageScore for a Mortgage? (What Changed in September 2026)

What Changed in September 2026

The short version: the menu of programs that can be underwritten on a VantageScore instead of — or alongside — a Classic FICO has widened. Earlier in 2026 the capability came online for VA loans (for credit reports newly attached or reissued on or after May 6, 2026) and for FHA Streamline refinances (on or after May 20, 2026). It has since been available on the conventional side as well. Taken together, as of September 2026 a borrower working with Lumen Mortgage can be evaluated on VantageScore 4.0 across most conventional, VA, and FHA Streamline scenarios. The direction of travel is clear. VantageScore 4.0 is now the modern, trended-data credit score in place across the government mortgage channels — Fannie Mae, Freddie Mac, the Federal Home Loan Banks, and the Department of Veterans Affairs — and on September 11, 2026 the Federal Housing Administration announced it will accept VantageScore 4.0 on **January 1, 2027**. FHA insures close to a fifth of the mortgages written in the U.S., so that date is the one to watch for standard FHA borrowers. What has *not* changed yet is just as important. Until that January 1, 2027 date arrives, standard, full-documentation FHA purchase and rate-and-term loans still require a Classic FICO score. And across every program, the credit-model choice doesn't loosen underwriting: the loan still has to satisfy the same documentation and qualifying standards it always did. VantageScore expands who can be scored — it doesn't change the rules that follow.

What VantageScore 4.0 Actually Is

VantageScore® 4.0 is a credit-scoring model built to evaluate a borrower's creditworthiness using historical data over time. The single most important difference from older models is that it reads **trending (trended) credit data**: instead of taking one point-in-time snapshot, it looks at whether your balances have been rising or falling month over month. A borrower steadily paying balances down reads differently than one whose balances are climbing, even at the same utilization. VantageScore describes 4.0 as the first tri-bureau model to incorporate trended credit data. The practical payoff is reach. According to VantageScore, the 4.0 model can score tens of millions more U.S. adults than earlier models — the company cites roughly 33 million additional scorable adults and coverage of about 94% of U.S. adults — using machine learning trained on the credit histories of consumers that lenders have historically overlooked, with the largest gains among people who have dormant credit histories or no active trade lines. It also doesn't require an extensive history: a score can be generated from as little as a one-month credit history. Where the model family is headed is toward broader inclusion still — expanded scoring designed to recognize responsible borrowers whose strongest record is things like rent, utility, and phone-bill payments rather than revolving credit. The through-line is the same: giving a lender a second, more modern model means we can fairly evaluate files that a Classic FICO alone doesn't tell the whole story about.

Where Each Loan Program Stands on VantageScore

Here is the current, program-by-program picture as of September 2026. Read the minimums as floors set by the program — the score required to be considered — not as the score that earns the best pricing, and read every row through the reminder that the full underwrite still governs the outcome. The table below summarizes the landscape; the details for each program follow underneath.

Conventional Loans: VantageScore Accepted (Minimum 640)

On the conventional side, VantageScore 4.0 is available for standard conventional loans, conventional high-balance loans, and conventional One-Time Close new-construction loans. The maximum loan-to-value is 97%, and the minimum VantageScore is **640**. That covers the large majority of conventional purchase and refinance scenarios. Some specialized down-payment-assistance and high-LTV cash-out programs may follow different credit-model rules, so if your scenario involves a niche program it's worth confirming up front — but for a straightforward conventional purchase or refinance, VantageScore is on the table.

VA Loans: The Broadest Coverage (Minimum 600)

VA financing has the widest VantageScore coverage of any program. It's available on VA purchases, VA IRRRLs (Interest Rate Reduction Refinance Loans), VA cash-out refinances, VA Jumbo loans, and VA One-Time Close new-construction loans. There is **no program maximum LTV**, the minimum VantageScore is **600**, and it applies to credit reports newly attached or reissued on or after May 6, 2026. There's a notable convenience feature for streamline-style refinances: **VA IRRRLs are eligible to close with a VantageScore-only soft-pull credit report**. A soft pull doesn't affect the borrower's credit, which fits the low-friction nature of an IRRRL. For eligible veterans who financed during a lower-rate window and are refinancing, or who are relocating and want to use their benefit again, the broader scoring flexibility can matter.

FHA: Streamlines Only — Standard FHA Still on Classic FICO

FHA is the program with the most important caveat. VantageScore 4.0 is available on **FHA Streamline refinances only**, for new or reissued credit on or after May 20, 2026. There is no program maximum LTV, and the minimum VantageScore is **600**. Like VA IRRRLs, FHA Streamlines are eligible to close with a VantageScore-only soft-pull credit report. What this means in practice: if you already have an FHA loan and want to streamline into a new one, VantageScore is available today. But if you're buying a home with a **standard, full-documentation FHA loan**, that program still requires a Classic FICO score for now. This is the single most common point of confusion, so it's worth stating plainly — FHA purchase money is not yet a VantageScore program. That is changing on a known date. On September 11, 2026, the FHA announced it will accept VantageScore 4.0 collateral starting **January 1, 2027** — the step that brings standard FHA in line with the other government channels. If you're planning a standard FHA purchase and your file scores better on VantageScore than on Classic FICO, that timeline is worth building into your plans; we'll flag it for borrowers where it matters.

How the Score Is Actually Used in Eligibility and Pricing

A couple of points here prevent the most common misunderstandings. First, using a VantageScore is not a discount. It does not, by itself, produce a lower interest rate. The credit model determines whether and how you can be *scored and considered* on a program — pricing is still driven by the full file, and a VantageScore simply lets more borrowers into the framework the industry already uses. **One model for all borrowers on the loan.** If more than one borrower is on the application, the same credit model must be used for everyone. You can't mix a VantageScore for one co-borrower and a FICO for another on the same file. In some situations the credit report itself includes both FICO and VantageScore 4.0; in others it's a VantageScore 4.0-only report — but the loan is evaluated on one consistent model. Underneath all of it is the point worth repeating: the credit model determines whether you can be *scored and considered*. It does not manufacture an approval, and it does not change the income, asset, and documentation requirements the loan has to meet. A weak file is still a weak file under either model.

Who Actually Benefits

VantageScore 4.0 is not a universal upgrade, and for most borrowers who already carry a strong Classic FICO it changes nothing. Where it genuinely opens a door is for a specific set of profiles: **Thin-file borrowers.** People who simply haven't used much revolving credit — younger buyers, recent arrivals to the U.S., people who prefer to pay cash — often have too little history for a traditional model to score. A model that can work from as little as one month of history may be able to produce a usable score where FICO returns nothing. **Dormant-history and no-trade borrowers.** VantageScore reports its biggest scoring gains precisely among people with dormant credit histories or no active trade lines — someone who paid off and closed accounts years ago and hasn't borrowed since. A trended, machine-learning model is designed to read that profile where an older model may not score it at all. **Credit rebuilders.** Someone recovering from a past setback whose recent history shows balances trending *down* and payments landing on time may be read more favorably by a trending-data model than by a point-in-time snapshot. For these borrowers, the value isn't a lower rate — it's the difference between having a scorable, workable file and not having one at all. That's the honest framing: VantageScore can make you *eligible to be considered* on a program you couldn't access before. It doesn't promise the outcome.
