Credit score requirements for mortgages are both simpler and more nuanced than most buyers expect. There’s a floor for each loan type — below which you won’t qualify at all — and a more important range where your score directly determines the interest rate you’re offered. The gap between a 680 and a 760 can be worth tens of thousands of dollars over the life of a loan.
Minimum Scores by Loan Type
| Loan type | Minimum score | Notes |
|---|---|---|
| Conventional | 620 | Most lenders; some require 640 |
| FHA | 580 (3.5% down) | 500–579 allowed with 10% down |
| VA | No official minimum | Most lenders require 580–620 |
| USDA | Typically 640 | For rural property programs |
| Jumbo | 700–720+ | Lender-specific; varies widely |
These are floor minimums. Meeting the minimum gets you in the door — it doesn’t get you the best terms.
How Your Score Affects Your Rate
Mortgage pricing uses loan-level price adjustments (LLPAs) — surcharges on the base rate that vary by credit score and loan-to-value ratio. The lower your score, the higher your rate adjustment.
The score tiers for conventional pricing are typically set in 20-point bands. Moving from 699 to 700 or from 719 to 720 can produce a meaningful rate improvement.
Illustrative rate impact on a $400,000 loan at 80% LTV:
| Credit score range | Approximate rate premium above best-tier |
|---|---|
| 760+ | None (best pricing) |
| 740–759 | Small premium |
| 720–739 | Moderate premium |
| 700–719 | Meaningful premium |
| 680–699 | Significant premium |
| 660–679 | Large premium |
| 640–659 | Very large premium |
A buyer with a 680 score might receive a rate 0.5%–0.75% higher than a buyer at 760+ on the same loan, all else equal. On a $400,000 loan, that difference adds roughly $130–$200/month to the payment and $50,000–$75,000 in total interest over 30 years.
What Goes Into Your Credit Score
The FICO score (the version mortgage lenders use) is based on five factors:
- Payment history (35%): On-time vs. late payments, collections, bankruptcies, foreclosures
- Amounts owed (30%): Credit utilization — how much of your available credit you’re using
- Length of credit history (15%): Age of oldest account, average age of all accounts
- New credit (10%): Recent hard inquiries, new accounts opened
- Credit mix (10%): Variety of credit types (revolving, installment, mortgage)
Practical Ways to Improve Your Score Before Applying
Lower your credit card utilization. This is the fastest lever. If your cards collectively have $20,000 in limits and you’re carrying $10,000 in balances, your utilization is 50%. Lenders prefer below 30%; below 10% is optimal for scoring. Paying balances down before applying can improve your score meaningfully within 30–60 days.
Don’t close old accounts. Closing a card reduces your available credit (raising utilization) and potentially shortens your average account age — both hurt your score. Leave unused cards open.
Don’t apply for new credit in the 6–12 months before applying for a mortgage. Each hard inquiry temporarily lowers your score. New accounts also shorten your average account age.
Dispute errors on your credit report. Pull your reports from all three bureaus at annualcreditreport.com and review for accounts that aren’t yours, incorrect late payments, or balances reported incorrectly. Disputes can take 30–45 days to process.
Pay any collections accounts strategically. Paying off a collection doesn’t always improve your score — it depends on the scoring model the lender uses. Under newer scoring models, paid collections have less impact than under older ones. Consult a loan officer before paying off collections, as the timing relative to your application matters.
How Mortgage Lenders Check Credit
Lenders pull from all three bureaus (Equifax, Experian, TransUnion) and use your middle score — not the average and not the highest. If your three scores are 710, 725, and 738, the lender uses 725.
When there are two borrowers (co-borrowers), the lender uses the lower of the two middle scores. If one borrower has a 760 middle score and the other has a 680, the loan is priced at 680.
Timing Your Application
If your score is on the edge of a pricing tier — say, 698 — spending 60–90 days paying down utilization to cross 700 could produce a better rate than applying now. Run the math: how much would the rate improvement save per month, and how does that compare to the cost of waiting?
The Affordability Calculator on LendingPulse lets you model payment and DTI at different rate scenarios, helping you quantify what a credit score improvement is actually worth in monthly dollars.
Frequently Asked Questions
What is the minimum credit score needed to buy a house?
Minimums vary by loan type: 620 for conventional loans, 580 for FHA with 3.5% down (500 with 10% down), no official minimum for VA loans though most lenders require 580–620 in practice, and typically 640 for USDA. Meeting the minimum gets you in the door — it doesn’t guarantee the best rate.
Does checking my credit score before applying for a mortgage hurt my score?
No. Checking your own credit is a soft inquiry and has no effect on your score. Only the lender’s hard inquiry during a mortgage application can temporarily lower your score, typically by a few points.
Which credit score do mortgage lenders use?
Lenders pull reports from all three bureaus — Equifax, Experian, and TransUnion — and use your middle score. With two co-borrowers, the lender uses the lower of the two middle scores to price and qualify the loan.
How long does it take to improve a credit score enough to qualify for a better mortgage rate?
Paying down credit card balances can improve your score within 30–60 days of the next statement closing. Disputing errors takes 30–45 days to resolve. Recovering from missed payments or collections typically requires 12–24 months of consistent on-time payment history.
