Updated November 4, 2026
You find a home you love, speak with a lender and discover that the credit score on your mortgage application does not match the number in your banking app.
That difference does not necessarily mean something is wrong. Credit scores come in different versions, and mortgage lending has its own scoring requirements.
Whether you are buying a home or refinancing, the first step is understanding which scores matter for your application. The next is getting your credit, income documents and savings ready before the lender starts reviewing them.
What is a mortgage score?
“Mortgage score” is a common way of describing a credit score used to evaluate a mortgage application. It is not one universal number.
The classic FICO® Scores used in mortgage lending are: [1]
Credit bureau | Classic mortgage score |
|---|---|
Experian | FICO® Score 2 |
Equifax | FICO® Score 5 |
TransUnion | FICO® Score 4 |
These differ from FICO® Score 8, which many consumers see through credit monitoring or a financial institution. You cannot reliably convert a FICO Score 8 into a mortgage score by adding or subtracting a fixed number of points. Score versions evaluate credit information differently, and bureau files can also differ. [1]
An important 2026 update
Classic FICO remains an approved option for loans sold to Fannie Mae and Freddie Mac. Eligible lenders can also use VantageScore® 4.0 under the agencies’ current requirements. FHFA says FICO 10T is not yet eligible for loan delivery to those agencies. [2]
Ask your lender: “Which credit scoring model will you use for my loan?” The answer can depend on the lender and mortgage program.
Which of my three mortgage scores will the lender use?
Under Fannie Mae’s representative-score rules, a lender generally selects the middle score when three scores are available for one borrower. With two scores, it selects the lower one. [3]
For example, suppose your three classic mortgage scores are:
Bureau | Illustrative score |
|---|---|
Experian | 710 |
Equifax | 728 |
TransUnion | 744 |
The middle score is 728, regardless of which bureau supplied it. It is not the average of the three.
For multiple borrowers, Fannie Mae’s representative score for pricing is generally the lowest of the borrowers’ applicable scores. Eligibility calculations can differ, including certain manually underwritten loans. Ask your lender how your program treats joint applicants. [3]
Why is my mortgage score different from the score in my app?
Check three details before comparing numbers:
Model: Is it FICO Score 8, a classic mortgage FICO Score or another model?
Bureau: Was it calculated using Experian, Equifax or TransUnion information?
Date: Were both scores calculated from the same reporting period?
A card payment or newly reported balance can change your credit file between score checks. Even matching models may produce different numbers when the bureau or calculation date differs. [1]
What is a good mortgage score?
There is no single score that guarantees approval or the best interest rate. A stronger credit profile can help, but lenders also assess the loan program and the rest of your application. Errors in your report can affect both eligibility and pricing, so review them well before applying. [4]
Instead of aiming for a general label such as “good,” ask your lender which score ranges affect the options and pricing available to you.
How to prepare your credit before you apply
1. Review all three credit reports early
Look for unfamiliar accounts, incorrect balances, inaccurate late payments and debts that do not belong to you. You can obtain free reports through AnnualCreditReport.com; reports and scores are different products.
Report genuine errors to the credit bureau and the company that supplied the information. Starting early gives you time to address problems before they complicate your application. [4][5]
2. Protect your payment record and reduce card balances
Keep every account current. Consider payment reminders or automatic minimum payments, with enough money in the payment account to cover them.
Pay attention to credit utilization: the reported balance compared with the card’s limit. A $2,000 balance on a $5,000 limit is 40% utilization; a $500 balance is 10%. Lower reported revolving balances can help your credit profile, but no particular reduction guarantees a score increase. You do not need to carry interest-bearing debt to build credit. [6]
3. Avoid new financial commitments before closing
A new vehicle loan, furniture financing or several credit card applications can change your debt obligations and credit profile. CFPB recommends avoiding new borrowing and large credit card purchases in the months before buying a home. [5]
Check with your loan officer before making a major financial change during the application process.
Get your finances ready—not just your score
Organize documents before the lender requests them. Depending on your employment, loan program and circumstances, the lender may ask for:
Recent pay stubs and W-2s.
Tax returns, particularly for self-employed borrowers.
Bank and investment statements.
Identification and information about existing debts.
Documentation for gift funds or other sources of closing money.
Ask for a checklist tailored to your application. For a purchase, discuss preapproval before making an offer; it remains subject to conditions and final review. [7]
Build your budget around the full cost of owning the home, including taxes, insurance, maintenance and any association dues. Keep room for closing costs, moving expenses and unexpected repairs rather than committing every available dollar to the down payment. [8]
Buying or refinancing? Start with your mortgage scores.
What should I check before refinancing?
A refinance replaces your existing mortgage with a new loan. Begin with a clear goal: reducing interest costs, changing the term, moving to a different loan structure or accessing equity. Bring your current mortgage statement and ask the lender to compare the existing loan with the proposed replacement. [9]
Review more than the new monthly payment:
Closing costs: What will you pay upfront or add to the balance?
Loan term: Are you extending repayment beyond your current payoff date?
Total interest: Does the new structure increase costs over the time you expect to keep the loan?
Equity: How does the estimated property value affect your options?
A lower monthly payment can partly reflect a longer repayment period. “No closing cost” offers can involve a higher rate or costs added to the loan. [10]
Calculate a simple break-even point
For a straightforward rate-reduction example:
Refinance costs ÷ monthly principal-and-interest savings = approximate break-even period
If refinancing costs $4,800 and saves $200 a month, the simple break-even point is 24 months.
This is a first screening tool. It does not capture every difference in loan balance, term, mortgage insurance or total interest. Compare the full loan terms, especially if you expect to move or refinance again soon. [11]
Compare loan offers before choosing
Request Loan Estimates from multiple lenders for comparable loan amounts and terms. Compare the rate, points, lender credits, upfront fees, monthly payment and cash needed to close. Estimates issued on different days can reflect changing market rates. [12]
Ask each lender to explain any large difference. Your credit score helps shape the offer, but it does not replace shopping around.
Frequently asked questions
Will checking my own mortgage scores hurt my credit?
Checking your own credit is a soft inquiry and does not lower your FICO Scores. A lender’s credit check for an application can be a hard inquiry. [13]
Can I know exactly what my lender will see?
A consumer score can help you prepare, especially when the model and bureau match. It cannot guarantee an exact match to a later lender pull because report information and scoring dates may change. [1]
Does refinancing require perfect credit?
No universal “perfect credit” requirement applies to every refinance. Requirements depend on the lender and program. Discuss your credit, income, debts and equity together to understand the options available. [9]
Know your scores before your next mortgage decision
Checking early gives you time to understand your credit reports, investigate errors and prepare questions for your lender. For a purchase, that can mean fewer surprises when you find the right property. For a refinance, it helps you evaluate the offer against your actual goal.
