Your App Says 750. Your Lender Is Looking at a Different Number Entirely.

Free credit apps generally show VantageScore or FICO 8. Mortgage lenders use older mortgage specific models, FICO 2, 4, and 5, pulled from all three bureaus. Gaps of 20 to 40 points are common in either direction, which is why the number on your phone rarely matches the one underwriting actually sees.

A Marine came to me this spring ready to buy his first house. He had been watching his score on a free app for a year, brought it from the low 600s up to 750, and was rightly proud of it. His lender pulled credit and the qualifying number came back in the 710s. Nothing was wrong. Nothing had changed overnight. He was just looking at a different scoring system than the one that was about to price his loan.

Here are the questions he asked, in the order he asked them, because they are the same ones almost everyone asks.

Why is the number different at all?

Because there are more than two dozen FICO versions in active use, and different industries pull different ones. The score your credit card app shows you is not the score a mortgage underwriter orders.

Those mortgage versions are older by design, and they weigh things differently. They lean harder on installment loan history and treat collections and thin files differently than the consumer models do. That is the entire source of the gap.

Worth noting that this is currently in motion. Federal housing regulators approved newer models years ago and the industry has been phasing them in, with additional milestones through 2025 and 2026. Which means the honest answer to "what model will my lender use" is to ask your specific lender rather than assume.

Which of the three scores counts?

The middle one. Your lender pulls all three bureaus in what is called a tri merge, lines up the three scores, and uses the one in the middle. Not the average, not the best.

So a file showing 705, 718, and 740 qualifies at 718. People fixate on their highest number, and the highest number is the one that matters least.

What if I am buying with my spouse?

This is the one that catches couples off guard. Each borrower gets their middle score determined, and then the lender generally uses the lower of those two middle scores to qualify the file.

Two strong credit profiles do not average out. The weaker one carries the pricing. For military buyers and first time buyers purchasing together, that is worth knowing months ahead of time, because it changes which balances are worth paying down first.

Does the VA set a minimum score?

No. The VA itself does not mandate a minimum credit score for a VA loan. What exists are lender overlays, meaning each lender sets its own internal floor, commonly somewhere in the 580 to 620 range.

That distinction matters more than it sounds. If one lender declines a veteran on score, that is that lender's rule, not a VA rule, and another lender may have a different floor. The VA also leans on residual income rather than a hard debt to income ceiling, which is why VA files approve in situations conventional files do not.

So what happened with the Marine?

Not much, honestly, which is the point. He was still well above every lender floor. The 710s priced slightly differently than the 750s would have, but he bought a house in San Diego North County that summer and the gap never became a problem.

Where it does become a problem is when someone is sitting near a threshold. A person who believes they are at 640 and is actually at 615 has a real issue, and they find out at the worst possible moment. Balances paid below 30 percent utilization can move a score 20 to 50 points in one to three months, but only if you know you need to do it.

Ask Your Lender This

Two questions to ask on your first call:

• "What scoring models will you actually use on my file, and can you run a soft pull now so I can see my tri merge scores?"
• "What is your internal minimum score for a VA loan, and where does my middle score put me on your pricing tiers?"

Frequently Asked Questions

Why is my mortgage credit score lower than Credit Karma?

Because Credit Karma reports VantageScore, not the mortgage FICO versions lenders order. The models weigh credit behavior differently. Differences of 20 to 40 points are common, and it can run in either direction depending on your profile.

Does checking my own credit hurt my score?

No. Checking your own credit is a soft inquiry and does not affect your score. Separately, mortgage inquiries made while shopping lenders within a short window are generally grouped as a single event, so comparing offers is not the penalty people fear.

Are free credit apps useless then?

Not at all. They are good for spotting errors, tracking direction over time, and catching something unexpected on your report. Just do not treat the number itself as your qualifying score.

How far ahead should I check before a PCS purchase?

Sooner than feels necessary. If a score needs work, the fixes take one to three months to show up, and a PCS timeline does not leave room for that once orders are in hand.

What did your app say versus what your lender actually pulled? Drop the gap in the comments, because the spread surprises almost everyone and it helps other buyers know what to expect. More on VA loans and buying in San Diego North County is on the blog.
