Why Is My Mortgage Credit Score Different From What I See Online?

Why Your Mortgage Credit Score May Be Different From the Score You See Online

Originally published March 7, 2013. Updated September 2026.

You check your credit score through your bank, credit-card company or Credit Karma, and it says 760. Then a mortgage lender pulls your credit and says your qualifying score is 723.

How can both scores be correct?

The short answer: You do not have one universal credit score. Your mortgage score may differ because the lender uses different credit bureaus, scoring models or more recently reported information.

Which credit score do mortgage lenders use?

Mortgage lenders traditionally obtain credit information from the three major credit bureaus:

• Equifax
• Experian
• TransUnion

When all three scores are available, the borrower’s representative mortgage score has generally been the middle score—not the highest score and not the average.

You might see the 760 online, while the mortgage lender uses 723.

When more than one person applies, the applicable loan program determines how the borrowers’ scores are evaluated. A co-borrower’s weaker credit profile may affect eligibility, pricing or mortgage-insurance costs.

Why can the scores be different?

There are four principal reasons:

Different credit bureaus

Your bank or credit-monitoring service may show a score based on only one bureau. A mortgage lender commonly reviews information from Equifax, Experian and TransUnion, which may not contain identical information.

Different scoring models

Credit Karma has traditionally shown VantageScores. Many banks and credit-card companies provide FICO Score 8. Mortgage lenders have traditionally used mortgage-specific FICO models.

All of these may be legitimate scores, but they are different products and should not be expected to match.

Even if your bank labels its score “FICO,” it may not be the particular FICO model used for mortgage lending.

Different reporting dates

Creditors generally report balances periodically rather than immediately after every payment or purchase. Your online score and mortgage score may therefore be based on information reported on different dates.

This can be especially important when credit-card balances are high relative to their limits.

Different information

A creditor may report to one bureau but not another. One report might also contain an incorrect late payment, collection, balance or account that does not appear on the other reports.

Are consumer credit scores intentionally inflated?

No. Consumer scores are not necessarily inaccurate or “fake,” and mortgage lenders do not lower credit scores.

A consumer score is simply not always the score used for a mortgage. It may come from a different bureau, use a different formula or reflect information from a different date.

There is also no reliable formula for converting a VantageScore or FICO Score 8 into a mortgage-specific score.

Mortgage credit scoring is changing

The mortgage industry is transitioning toward newer scoring models, including VantageScore 4.0 and FICO 10T. The scoring model used may increasingly depend on the lender, loan program, investor and implementation timing.

This makes it even more important to ask:

Which credit bureau and scoring model produced this score?

How can you prepare before applying for a mortgage?

• Review all three reports at AnnualCreditReport.com.
• Correct legitimate errors before applying.
• Make every payment on time.
• Keep reported credit-card balances low relative to their limits.
• Avoid opening or closing accounts shortly before applying without discussing it with your mortgage professional.
• Do not assume the score shown by a free app will be your mortgage score.

Paying down a credit card may help, but the lower balance ordinarily must be reported to the credit bureaus before it can affect your score.

Frequently asked questions

Why is my Credit Karma score different from my mortgage score?

Credit Karma has traditionally provided VantageScores, while mortgage lenders have traditionally used mortgage-specific FICO models. The two scores may also use information from different bureaus or dates.

Is the FICO score from my bank my mortgage score?

Not necessarily. Your bank may provide FICO Score 8 or another version. It can be a genuine FICO score without being the model used for your mortgage.

Does a mortgage credit inquiry lower my score?

A mortgage inquiry may have a relatively small effect, but it generally does not explain a large immediate difference between your online score and mortgage score. Scoring models also generally recognize multiple mortgage inquiries made during an applicable rate-shopping period as one inquiry for scoring purposes.

The bottom line

The score shown by your bank, credit-card company or monitoring app may be legitimate, but it may not be the score used for your mortgage.

Check which bureau supplied the information, which scoring model was used and when it was calculated. Identifying differences early can help you avoid unexpected changes to your mortgage eligibility, interest-rate pricing or mortgage-insurance costs.

The Consumer Financial Protection Bureau explains that scores can differ because of the scoring model, source of the credit information and calculation date.
