Key Takeaways
Credit Score & Mortgage Eligibility
A credit score is a three-digit number — typically ranging from 300 to 850 — that summarizes how reliably you've managed borrowed money over time. Mortgage lenders use this score as a key signal of lending risk: the higher your score, the more confident a lender generally is that you'll repay the loan. Your score directly influences whether you qualify for a mortgage, what interest rate you're offered, and what loan programs are available to you.
Most mortgage lenders rely on FICO® Score models, though Fannie Mae and Freddie Mac have been expanding acceptance of VantageScore models in conforming loan underwriting. Lenders typically pull scores from all three major bureaus — Equifax, Experian, and TransUnion — and use the middle score for qualification purposes.
Why Lenders Care So Much About Your Credit Score
When a lender considers your mortgage application, they're trying to answer one central question: how likely is this person to repay a large loan over decades? Your credit score is a compressed, data-driven attempt to answer that question in a single number.
Scores are calculated from your credit report, which tracks things like payment history, how much of your available credit you're using (utilization), the length of your credit history, types of accounts, and recent applications for new credit. Payment history carries the most weight — consistent on-time payments are the single strongest driver of a high score.
Lenders use score thresholds to set internal policies. Many conventional lenders won't approve an application below 620. But qualifying is just the floor — the rate and terms you receive are heavily shaped by where your score falls within the qualifying range. Understanding this relationship is foundational to the broader picture of healthy financial decision-making.
620
Common minimum score for conventional loans
Most conventional mortgage lenders set 620 as the floor for qualification, according to Fannie Mae guidelines, though individual lenders may require higher.
~1%+
Rate gap between lowest and highest score tiers
Borrowers with scores in the 620s may pay a full percentage point or more above what borrowers with 760+ scores receive, according to general mortgage pricing data from the Consumer Financial Protection Bureau.

Credit bureaus lenders typically check
Most mortgage lenders pull credit reports from Equifax, Experian, and TransUnion, using the middle of the three resulting scores for underwriting purposes.
Score Ranges and What They Generally Mean for Mortgage Terms
While exact cutoffs vary by lender and loan product, credit scores are commonly grouped into broad tiers that signal different levels of borrower risk:
- 760 and above: Generally considered excellent. Borrowers in this range typically qualify for the most competitive interest rates lenders offer.
- 700–759: Considered good. You'll likely qualify for most loan products, with rates close to — but slightly above — the best available.
- 640–699: Fair. You can still qualify for conventional and government-backed loans, though rates will be higher and lenders may scrutinize other factors more closely.
- 580–639: Below average for conventional loans. FHA loans become a more common path here, but expect higher rates and possible additional requirements.
- Below 580: Qualifying for a standard mortgage is difficult. FHA allows scores as low as 500 with a 10% down payment, but few lenders actively offer that product.
It's worth pairing your understanding of credit scores with other key metrics lenders watch. Your debt-to-income ratio — the share of your monthly gross income going toward debt payments — is evaluated alongside your score and can override a strong credit profile if it's too high.
Check Your Credit Before Lenders Do
Pull your credit reports from AnnualCreditReport.com before starting your mortgage search. Reviewing your own reports is a soft inquiry and won't affect your scores. This gives you time to dispute errors or address issues before a lender's hard pull.
Loan Types and Their Credit Score Considerations
Different mortgage programs are structured around different borrower profiles. Here's a general overview:
- Conventional loans
- Backed by private lenders and sold to Fannie Mae or Freddie Mac. Typically require a 620 minimum score. Borrowers with scores above 740 tend to see the most favorable pricing on these loans.
- FHA loans
- Insured by the Federal Housing Administration and designed for buyers who may have limited down payments or lower scores. A 580 score qualifies for 3.5% down; 500–579 requires 10% down. Mortgage insurance premiums are required regardless of down payment size.
- VA loans
- Available to eligible veterans, active-duty service members, and surviving spouses. The VA itself doesn't set a minimum score, but most lenders impose one — typically 580 to 620.
- USDA loans
- For eligible rural and suburban buyers. No down payment required, and lenders generally look for scores of 640 or higher for streamlined underwriting.
Choosing between loan types also intersects with rate structure decisions. See our guide to fixed-rate vs. adjustable-rate mortgages to understand how rate type interacts with the terms your score helps unlock.
Steps That Can Strengthen Your Score Before Applying
If your score isn't where you'd like it to be, deliberate action in the months before you apply can make a measurable difference. None of these steps guarantee a specific outcome, but they represent well-established credit fundamentals:
- Pay down revolving balances. Credit utilization — how much of your available credit limit you're using — has an outsized effect on your score. Bringing card balances below 30% of their limits (and ideally lower) can produce relatively quick score improvements.
- Avoid opening new credit accounts. Each new application generates a hard inquiry and lowers the average age of your accounts. Hold off on new credit cards or car loans in the months before a mortgage application.
- Dispute errors on your credit report. You're entitled to a free report from each major bureau annually at AnnualCreditReport.com. Errors — including accounts that aren't yours or incorrectly reported late payments — can be disputed and corrected.
- Keep existing accounts open. Closing old credit cards can reduce your available credit and shorten your credit history, both of which can lower your score.
