Mortgage lenders use credit scores to estimate repayment risk and help determine eligibility and pricing, but a FICO score alone does not approve or deny a mortgage. Lenders also assess the credit report, income, assets, debts, and ability to repay. The score model and version can vary by loan program and underwriting path, so the number in a consumer credit app may not be the one used for a mortgage decision.
What a FICO score tells a mortgage lender
A credit score is calculated from information in a credit report. FICO is one brand of credit score, and it offers multiple versions that can evaluate report information differently; some versions are designed for or used in home-loan decisions. As a result, scores shown by a bank, card issuer, or credit-monitoring app may differ from the mortgage score a lender obtains.
Mortgage lenders commonly review credit files from Equifax, Experian, and TransUnion. Scores and report details can differ among bureaus, and the Consumer Financial Protection Bureau (CFPB) says lenders often use the middle score when deciding what rate to offer. A lender’s review may also include its own history with the applicant. CFPB: Does my credit score affect my ability to get a mortgage loan or the mortgage rate I pay?

Because the score reflects report data, an error or an outdated account in a bureau file can affect the score and potentially influence eligibility or pricing. Check your reports and dispute inaccurate information before applying when possible.
How scores affect approval and mortgage rates
A score helps a lender estimate credit risk and assess whether an application fits its loan program. Higher scores generally correspond to better rate offers, but no score band guarantees approval or a particular rate. The lender, loan type, credit report, and other parts of the application all matter.
CFPB consumer guidance describes broad patterns, not universal underwriting cutoffs:
- Below 620: borrowers typically have trouble qualifying, according to CFPB guidance.
- 620–680: borrowers often have fewer choices and may have difficulty qualifying, depending on the loan and lender.
- About 680–740: borrowers generally pay somewhat higher rates.
- Mid-to-high 700s or above: borrowers generally have the broadest choices and lowest rates.
These ranges are explanatory guidance, not guaranteed thresholds or rate quotes. CFPB notes that some loans may require a minimum score of 620, but requirements vary. CFPB: Your credit history and score

Why credit score is only one part of underwriting
For covered dwelling-secured loans, federal ability-to-repay rules require creditors to make a reasonable, good-faith assessment that a borrower can repay. Relevant considerations include income or assets, debt obligations, and debt-to-income ratio or residual income. The rule does not set one universal DTI limit or credit-score cutoff. 12 CFR 1026.43
In practice, lenders consider the complete application: credit history and report details, current income, savings and other assets, existing debts, and the proposed loan. A strong score cannot by itself compensate for an application that does not meet the program’s repayment or documentation requirements.
Which score model could a lender use?
The model depends in part on the loan and how it is underwritten or delivered. As of September 9, 2026, the Federal Housing Finance Agency (FHFA) says lenders approved by Fannie Mae or Freddie Mac may use VantageScore 4.0 for eligible loans sold to those housing-finance companies, without prior written approval. Classic FICO remains an option. This is not a rule that every mortgage lender, loan type, or government-backed program uses the same score model. FHFA: Expanded credit-score options
For Fannie Mae loans, current guidance distinguishes automated and manual underwriting:

The lender must request it from all three bureaus and use the same model for all borrowers on a single loan.
- Manually underwritten loans continue to use Classic FICO under Fannie Mae’s guidance.
- FICO Score 10T has been approved by FHFA but is not yet available for Fannie Mae loan deliveries.
Fannie Mae’s requirements apply to its eligible deliveries; they should not be assumed to describe every lender or program. Fannie Mae Selling Guide: General Requirements for Credit Scores and Fannie Mae: Credit Score Models
FHFA approved FICO 10T and VantageScore 4.0 in 2022 for potential use by Fannie Mae and Freddie Mac. The models can incorporate additional payment-history information, such as rent, utility, and telecommunications payments, when that information is available. That does not mean those payments appear in every borrower’s file or that every lender currently uses FICO 10T. FHFA: Approval of updated credit-score models

FHA loans can allow lower credit scores than most conventional loans, but eligibility is not determined by score alone. Mortgage insurance and the total cost of the loan also matter. Compare actual offers using the rate, fees, down payment, insurance costs, and overall borrowing cost—not just a stated score threshold. CFPB: Compare loan options
Quick Recap
What to do before a mortgage lender checks your credit
- Review your credit reports. Check the bureau files a lender may use and dispute errors well before applying so there is time for corrections to be reflected. CFPB guidance
- Avoid unnecessary new credit. Applying for a credit card or auto loan shortly before or during the mortgage process can lower scores and change your debt picture. CFPB: What happens when a mortgage lender checks my credit?
- Shop mortgage lenders in a focused window. CFPB says multiple mortgage credit checks within a 45-day window are recorded as one inquiry. This applies to mortgage checks, not a blanket rule for every type of credit application. CFPB guidance, last reviewed August 28, 2026
- Ask how your application will be evaluated. Confirm the loan program, score model and version, bureau data, and whether underwriting is automated or manual. These details can matter as VantageScore 4.0 becomes available for eligible loans sold to Fannie Mae and Freddie Mac.
- Compare complete offers. Review rate, fees, mortgage insurance, down payment, and total cost alongside the lender’s score requirements and treatment of income, assets, debts, and other qualifying factors.
