What Credit Score Do You Need to Buy a House

Your credit score is one of the most influential numbers in the home buying process. It determines whether you qualify for a mortgage, which loan programs are available to you, and what interest rate you will pay. A difference of 80 to 100 points in your score can add or remove hundreds of dollars from your monthly payment.

This guide explains the minimum scores required by each major loan type, how your score translates into a specific rate, what that rate does to your monthly payment, and what you can do to improve your score before applying.

Higher score lowers rate

Going from 620 to 740 can cut your mortgage rate by 1.0% to 1.5%, saving hundreds per month.

Different loans have different rules

FHA, VA, USDA, and conventional loans each have distinct score minimums and insurance requirements.

Credit affects monthly payment

On a $350,000 loan, the difference between a 620 and 740 score can mean $349 more per month.

Improving score saves money

Even a 40- to 60-point improvement before applying can reduce your lifetime interest cost by $30,000 or more.

What Credit Score Do You Actually Need?

Most buyers need a credit score between 620 and 740 to qualify for a mortgage, but higher scores almost always mean lower interest rates and lower monthly payments. Even small score changes can affect total cost.

The minimum to qualify is not the same as the score you should aim for. Qualifying at 620 gets you in the door; a score of 740 or higher gets you the best available rate. The sections below show exactly what that difference costs.

Minimum Credit Scores by Loan Type

Each major mortgage program has its own credit floor. Falling below the minimum disqualifies you from that loan type entirely. Clearing the minimum gets you approved; your rate within each program is still determined by how far above the minimum you land.

Important distinction

Minimum score requirements above are program guidelines. Individual lenders often impose their own overlays, which are stricter internal requirements layered on top of the program minimums. A lender may require 640 for an FHA loan even though the program allows 580. Always confirm lender-specific requirements when you apply.

How Your Credit Score Affects Your Mortgage Rate

Mortgage rates are not fixed across all borrowers. Lenders use risk-based pricing, which means the interest rate offered to any individual borrower reflects the lender's assessment of the likelihood that borrower will repay. Your credit score is the primary input in that assessment.

On conventional loans, lenders use a pricing grid that ties specific rate adjustments (called loan-level price adjustments, or LLPAs) to credit score tiers and loan-to-value ratios. A borrower with a 740 score on a $350,000 purchase with 10% down will receive a materially lower rate than a borrower with a 660 score on the same purchase.

The relationship is not perfectly linear. Score improvements tend to produce the biggest rate drops at the major tier boundaries: moving from below 620 to above 620, from below 660 to above 660, from below 680 to above 680, and from below 740 to above 740. Crossing these thresholds can produce rate drops of 0.25% to 0.5% or more at each step.

How Rate Changes Affect Your Monthly Payment

On a fixed-rate mortgage, your monthly principal and interest payment is determined entirely by three inputs: the loan amount, the interest rate, and the loan term. Everything else held equal, a lower rate means a lower payment.

The relationship is not always intuitive because of how amortization works. A 1.0% rate increase on a $350,000 loan adds roughly $230 to the monthly payment. On a $600,000 loan, the same 1.0% rate increase adds roughly $395 per month. The dollar impact scales with the loan balance.

Over a 30-year loan, that monthly difference compounds into a very large total. On a $350,000 loan, a 1.0% higher rate costs roughly $83,000 more in total interest paid over the life of the loan. A 0.5% rate difference costs roughly $40,000 more. These are not small numbers, which is why optimizing your credit score before applying is one of the highest-return financial preparations a buyer can make.

How to Improve Your Credit Score Before Buying

Your credit score is calculated from five factors, each weighted differently. Knowing which factors matter most helps you prioritize your improvement efforts in the months before you apply.

Pay down revolving balances (35% weight on utilization)

Credit utilization, the percentage of your available revolving credit you are using, is the fastest-moving factor in your score. Reducing balances below 30% of each card's limit can improve your score within one to two billing cycles. Below 10% utilization typically yields the best scoring outcome. If you have $20,000 in available credit and carry $8,000 in balances, you are at 40% utilization. Paying that down to $6,000 brings you to 30%, and to $2,000 brings you to 10%.

Make every payment on time (35% of score)

Payment history is the single largest component of your FICO score. A single 30-day late payment can drop a good score by 60 to 110 points. If you have recent late payments, the most important thing you can do is establish a clean streak going forward. Set up autopay for at least the minimum on every account to prevent future misses. Late payments typically remain on your report for seven years, but their scoring impact fades significantly after two to four years.

Avoid opening new accounts before applying (15% on length)

Opening new credit accounts lowers your average account age and generates a hard inquiry, both of which can temporarily suppress your score. In the six to twelve months before you plan to apply for a mortgage, avoid opening any new credit cards or financing any major purchases. Even a 10 to 20 point temporary drop from a new account can push you below a key scoring tier and cost you a better rate.

Dispute errors on your credit reports

Errors are more common than most people expect. A Federal Trade Commission study found that roughly one in five consumers had a verifiable error on at least one credit report. Errors can include incorrect late payment entries, duplicate accounts, accounts that belong to someone else, and balances that have not been updated after payoff. Pull your reports from all three bureaus at AnnualCreditReport.com, review each one carefully, and file disputes in writing for any inaccuracies. Bureaus have 30 days to investigate and respond.

Do not close old accounts

Closing an old credit card reduces your total available credit, which raises your utilization ratio, and shortens your average account age. Both effects can lower your score. Keep old accounts open even if you do not use them regularly, unless there is an annual fee you cannot justify. A dormant account with a zero balance and no annual fee is helping your score simply by existing.

Frequently Asked Questions

What is the minimum credit score needed to buy a house?

The minimum depends on the loan type. Conventional loans require a 620 minimum in most cases. FHA loans accept scores as low as 580 with 3.5% down, or 500 with 10% down. VA loans have no official minimum, though most lenders impose a 580 to 620 floor. USDA loans typically require a 640 score for streamlined underwriting. These are minimums to qualify, not targets for the best rate. A score of 740 or higher generally gets you the best available interest rate on a conventional loan.

How much does a higher credit score actually save on a mortgage?

The savings can be significant over the life of a loan. On a $350,000 30-year fixed mortgage, a borrower with a 760 score might receive a 6.00% rate, while a borrower with a 640 score might receive 7.00%. That one percentage point difference equals roughly $231 more per month, or about $83,000 more in total interest paid over 30 years. Even a 0.5% rate difference on the same loan adds up to roughly $40,000 over the full term.

Does checking my credit score hurt my chances of getting a mortgage?

Checking your own credit score (a soft inquiry) has no impact on your score. Hard inquiries from lenders do temporarily lower your score by a few points, but multiple mortgage applications submitted within a 14 to 45 day window are treated as a single inquiry for scoring purposes. You can and should apply to multiple lenders to compare rates without worrying about multiple hard pulls damaging your score, as long as you do all applications in a concentrated window.

How long does it take to improve a credit score enough to qualify?

It depends on what is dragging your score down. Paying down high balances can produce measurable improvement within one to two billing cycles, since utilization is updated monthly. Establishing a new positive payment history takes several months of consistent on-time payments to move the needle. Negative marks like late payments and collections take longer: they fade in scoring impact over two to four years and are removed entirely after seven years. Most borrowers with a score in the 580 to 620 range can reach 680 or higher within six to twelve months with disciplined effort.

Does applying to multiple mortgage lenders hurt my credit score?

No, as long as you apply within a concentrated window. Credit scoring models treat multiple mortgage inquiries made within 14 to 45 days (depending on the scoring model) as a single inquiry. This is specifically designed to allow rate shopping. Apply to all lenders you are comparing in the same two-week period to ensure they are grouped into one inquiry event.

Can I buy a house with bad credit?

Yes, though your options narrow and your cost increases at lower scores. FHA loans accept scores as low as 500 with a 10% down payment. Below 500, most conventional paths are closed, but manual underwriting programs exist for borrowers with extenuating circumstances. The trade-off for a low credit score is a higher interest rate, a larger required down payment, and potentially mortgage insurance costs on top of that. In most cases, spending six to twelve months improving your score before applying is more cost-effective than accepting a high-rate loan today.
