Thinking about buying a house someday? Your credit score is going to be one of the first things lenders check. But the exact number you need depends on what type of mortgage you're getting.

The good news is that you don't need a perfect credit score to buy a home. Even with less-than-ideal credit, options exist. The not-so-good news is that your credit score directly affects whether you qualify and how much you'll pay in interest over the life of your loan.

Let's break down the real numbers and what they mean for your home-buying goals.

Minimum Credit Scores by Mortgage Type

Not all mortgages have the same requirements. Different loan programs cater to different credit levels.

FHA loans: 580 to 620 is the typical range. Some lenders go as low as 500 with a larger down payment.

Conventional loans: Most lenders want 620 as a minimum, though some go down to 580. Many prefer 640 or higher.

VA loans: 580 to 620, though VA loans are more flexible with credit scores than other types.

USDA loans: Similar to VA loans, 580 minimum, though 620 is more common.

Jumbo loans: These are for expensive homes. You'll typically need 700+.

These minimums are just the floor. You might qualify with a 580, but you won't get the best interest rates. Lenders see scores in the 620-650 range as higher risk, so they charge more to cover that risk.

FHA Loans: The Low-Credit-Score Option

FHA loans (backed by the Federal Housing Administration) are designed to help first-time and lower-credit homebuyers. This is why they have the lowest credit requirements.

With an FHA loan, you can buy a house with a 580 credit score and just 3.5% down. Some lenders will even go lower to 500 with more money down.

The trade-off? FHA loans require mortgage insurance, which is an extra monthly payment on top of your mortgage. This insurance protects the lender if you default. On a $200,000 loan, that insurance might add $200 to $400 per month to your payment.

FHA loans are still a solid choice for people building credit or with recent financial problems. They're more forgiving than conventional loans, and they help you get into a home while you continue building your credit.

Conventional Loans: What Scores Qualify

Conventional mortgages aren't backed by the government. These are loans that banks offer themselves, and they're stricter about credit.

The official minimum is usually 620, but many lenders prefer 640 or higher. The better your score, the better your interest rate and terms.

With a conventional loan and a score in the 620-650 range, you'll pay a higher interest rate than someone with a 750 score. On a $300,000 loan, the difference could be 0.5% to 1% in interest rate. Over 30 years, that's tens of thousands of dollars more.

The upside is that conventional loans don't require mortgage insurance if you put down 20%. This can save you hundreds of dollars per month compared to an FHA loan. But you need either a higher credit score or more cash for the down payment.

VA and USDA Loan Requirements

VA loans are available to military members, veterans, and their spouses. They typically require a 580 to 620 credit score, though some VA lenders go lower.

VA loans are incredibly borrower-friendly. They often don't require a down payment, don't require mortgage insurance, and have flexible underwriting. Even with a lower credit score, a VA loan might give you better terms than an FHA or conventional loan.

USDA loans are for rural homebuyers. They're backed by the USDA and require a 580 minimum, though 620 is more common.

Like VA loans, USDA loans don't require a down payment and don't require traditional mortgage insurance. If your credit is lower but you're buying in a USDA-eligible area, this is worth exploring.

How Your Score Affects Your Interest Rate

Here's where your credit score hits your wallet. On a $300,000 mortgage:

740+ score: 6.5% interest rate = about $1,896 monthly payment (30-year)

700-739 score: 6.75% interest rate = about $1,996 monthly payment

680-699 score: 6.95% interest rate = about $1,996 monthly payment

660-679 score: 7.15% interest rate = about $2,046 monthly payment

640-659 score: 7.35% interest rate = about $2,097 monthly payment

620-639 score: 7.75% interest rate = about $2,198 monthly payment

Notice the pattern. Each drop in credit score adds about 0.25% to your interest rate. Over 30 years, that 1.5% difference between 620 and 740 adds up to nearly $100,000 more paid in interest.

This is why building your credit before you buy matters. Even improving your score by 50 points can save you thousands. Understand your credit score ranges to see where you stand relative to home-buying benchmarks.

Steps to Raise Your Score Before Buying

If you're not ready to buy yet, here's what to do:

Pay all bills on time: This is the biggest factor. Even one late payment stays on your report for 7 years.

Lower your credit utilization: Pay down revolving debt. If you have $10,000 in credit card debt and $20,000 in available credit, you're at 50% utilization. Get it below 30%. Understanding credit utilization ratio shows why this matters so much.

Don't apply for new credit: Each application triggers a hard inquiry, which temporarily lowers your score.

Dispute errors on your report: Check your credit report and challenge any mistakes. Wrong information can drag your score down.

Become an authorized user: If someone with good credit adds you to their card, their payment history might boost your score.

Use a credit builder card: Products like a credit builder card let you build credit safely while preparing for homeownership.

These moves typically take 6 to 12 months to show meaningful results, but waiting is better than buying with a 580 score and paying 1.5% more in interest for 30 years.

How Long Does It Take to Qualify

The timeline depends on where you're starting from:

No credit history: 12 to 18 months to reach 620 with responsible use of a credit card.

Fair credit (580-620): 6 to 12 months to reach 640 with consistent payments and lower utilization.

Good credit (700+): You're ready now. Don't wait.

Rebuilding after past problems: 2 to 3 years to reach 620 after a late payment, charge-off, or bankruptcy.

Most lenders want to see you in the 640-680 range before they approve you without major caveats. That's the sweet spot where you'll get decent terms and reasonable interest rates. Learning how long to build credit helps you set realistic expectations.

FAQ

Q: Can I get approved for a mortgage with a 550 credit score? A: Unlikely. Most lenders won't touch anything below 580, and those that do require a substantial down payment and charge much higher rates.

Q: How much down payment do I need with a lower credit score? A: FHA loans let you put down 3.5% with a 580 score. Conventional loans typically require 5-10% with scores in the 620-650 range. A co-signer might let you put down less.

Q: Does my partner's credit score matter if we buy together? A: Yes. If you're both on the mortgage, both scores are considered. The lender usually uses the lower score.

Q: How long after building my credit should I apply for a mortgage? A: Wait at least 3 to 6 months after your last negative item or after opening new accounts. Lenders want to see stability.

Q: Will paying off debt lower my credit score? A: Possibly, at least temporarily. Paying off a credit card account might lower your score slightly if it's your only card. But the long-term benefit far outweighs the short-term dip.
