Why Is My Mortgage Credit Score Different From Credit Karma?
Mortgage lenders use older FICO versions pulled from all three bureaus. Here is why that number is usually lower than the score in a free app.
Updated 2026-08-21| Applies to: Anyone comparing a free credit app to a lender's credit pull.
The short answer
Free apps typically show VantageScore models built on one or two bureaus. Mortgage lenders pull all three bureaus using older, mortgage specific FICO versions and use the middle score. Different model, different data, different number, and the mortgage version is often lower.
There is no single credit score. There are dozens of scoring models, and the one you see for free is usually not the one a mortgage underwriter sees.
The three differences
| Difference | What it means |
|---|---|
| Model | Consumer apps commonly use VantageScore; mortgage lenders use FICO versions built for mortgage lending |
| Bureaus | Apps often show one or two bureaus; mortgage pulls include Equifax, Experian and TransUnion |
| Which number counts | Lenders take the middle of three scores for one borrower, and the lower middle score when two people apply |
How the qualifying score is picked
If your three scores are 704, 688 and 671, your qualifying score is 688. If a co borrower's middle score is 662, most programs use 662 for pricing and eligibility.
What actually moves the mortgage score
- Credit card balances relative to limits, which is usually the fastest lever
- On time payment history
- Recent new accounts and hard inquiries
- Collections, charge offs and public records
- Length and mix of credit
Do not close old accounts or pay off collections to chase a score without talking to your loan officer first; some moves lower the score before they help.

- Credit Score
- A number lenders use to summarize credit risk. Mortgage lenders typically use specific FICO versions and often the middle of three bureau scores.
- Pre Approval
- A lender's written statement of how much you can likely borrow after reviewing your credit, income and assets. It is based on documentation, not just a conversation.
