Minimum Credit Score Needed to Buy a House

You usually need a credit score between 500 and 720 to buy a home, depending on the loan type. Lenders also check your income, debts, and down payment when setting your terms and interest rates.

How Your Credit Score Influences Interest Rate and Loan Pricing

Your credit score affects not only whether you qualify but also how much your mortgage costs over time. Higher credit scores signal lower risk to lenders, and lenders use those scores to set interest rates and pricing adjustments. 

According to the Consumer Financial Protection Bureau, consumers with higher credit scores generally receive lower interest rates on mortgages, while lower credit scores often result in higher rates and added costs.

Minimum Credit Score by Mortgage Type

Each mortgage program has different minimum credit scores. FHA loans may accept scores as low as 500, but you’ll need 580 or higher for the lowest down payment. Conventional loans typically require a minimum of 620, with 720 or above getting the best rates. 

VA and USDA loans often accept scores around 580–620, though some lenders ask for more. Jumbo loans usually require at least 680–700. The median credit score for many homebuyers is around 700–720, which helps explain why those ranges get the best pricing.

Why Lenders Set Minimum Credit Scores

Lenders use minimum credit scores to judge how likely you are to repay the loan. A higher score shows a history of on-time payments and lower risk, which earns you lower interest rates. Lower scores signal higher risk, so lenders may require larger down payments, higher rates, or deny the loan.

Agencies like Fannie Mae, Freddie Mac, and the FHA have specific score guidelines that lenders must follow to sell loans on the secondary market. That’s why different lenders may give you different answers.

Exceptions to Standard Credit Score Rules

You can still get a mortgage with a lower score if you have a large down payment, low debt-to-income ratio, steady job history, or strong cash reserves. Some lenders offer manual underwriting for borrowers with limited or imperfect credit histories.

Co-borrowing with someone who has a higher score can help, but lenders use the lower middle score. Some first-time buyer programs or community lenders may have more flexible rules.

How Credit Score Affects Your Mortgage Options

Your credit score affects which loans you can get, your interest rate, and how much of your monthly payment goes to principal and interest. Even small changes in your score can affect your rate and the total cost of your loan.

Credit Score Ranges and Ratings

Lenders use FICO scores from 300 to 850. Common brackets are:

  • 800–850: Exceptional — you get the best mortgage interest rates.

  • 720–799: Very good — strong chance for low rates on conventional loans.

  • 670–719: Good — you qualify for most mortgages, but rates rise slightly.

  • 580–669: Fair — FHA loans often accept this range; conventional loans may require higher down payments.

  • 300–579: Poor — few options; you may need larger down payments or special loan programs.

Know your exact FICO score before you apply. Lenders check scores from the three bureaus and use the middle or the one tied to mortgage underwriting. The average U.S. credit score is often in the 600–750 range, so small improvements can move you into a better bracket.

Impact on Mortgage Interest Rate

Your credit score is a main driver of the mortgage interest rate you’re offered. Higher scores qualify you for lower rates, sometimes by several tenths of a percent. Even a small difference in rate can save thousands over a 30-year loan.

Lenders raise rates for lower scores because they see more risk. Loan type matters too—conventional loans usually need a 620–680 score, FHA loans accept lower scores but may charge higher rates. 

Jumbo loans and the best rates usually require 700+ scores. Always get specific rate quotes before locking in a mortgage.

Effect on Monthly Payments

Your credit score affects your mortgage interest rate, which changes your monthly payment. For the same loan amount, a higher rate increases your monthly payments and total interest. For example, on a $300,000 30-year loan, a 0.5% higher rate can raise your payment by hundreds of dollars per month. 

Lower scores may also require larger down payments or private mortgage insurance, which affect your upfront and monthly costs. Run payment estimates at different rates to see the impact on your budget.

Credit Score Requirements by Loan Type

Each loan program has its own score requirements. Some let you qualify with lower scores but may add costs like mortgage insurance or higher rates. Choose the program that fits your score and budget best.

Conventional Loans and Credit Scores

Conventional loans follow Fannie Mae or Freddie Mac rules. Many lenders look for scores of 660–720 to get the best rates and avoid extra fees, though the baseline minimum is often 620.

If your score is below the threshold, you may still qualify but will likely face higher rates or need a larger down payment. Private mortgage insurance (PMI) applies if you put down less than 20% and raises your payment until you reach 20% equity.

Conventional loans must meet conforming loan limits. Higher loan amounts or weaker credit may push you toward other loan types or jumbo loans.

FHA Loans: Lower Credit Score Options

FHA loans accept lower credit scores than conventional loans. You can often qualify with a score around 580 and a 3.5% down payment. Some lenders take scores between 500 and 579, but usually require a 10% down payment.

FHA loans charge upfront and annual mortgage insurance premiums (MIP), which stay on the loan for many years and can raise your lifetime cost compared with conventional loans that remove PMI at 20% equity.

FHA loans work well if you have a blemished credit history or a small down payment.

VA and USDA Loans: Special Considerations

VA loans, for veterans and eligible service members, don’t require a set minimum credit score from the VA, but most lenders want at least 620. VA loans don’t require mortgage insurance, but you may pay a funding fee.

USDA loans, for rural buyers, often accept scores around 640 through automated underwriting. USDA loans don’t require PMI but do charge a guarantee fee, which adds to your costs.

Both VA and USDA loans have other rules—like service eligibility for VA loans and property location and income limits for USDA loans. These factors can matter more than a few points on your score.

Jumbo and Non-Qualified Mortgages

Jumbo loans go above conforming loan limits and need stronger credit. Lenders usually want scores of 700 or higher and larger down payments. They also require lower debt-to-income ratios and more reserves.

Non-qualified mortgages (non-QM) serve buyers who don’t meet standard rules, like the self-employed. Credit score requirements vary; some non-QM lenders accept lower scores but charge higher rates and fees.

With jumbo or non-QM loans, gather strong documentation and shop around. Compare rates, required reserves, and whether you can refinance into a conforming loan later if your credit or equity improves.

Other Factors Lenders Consider Besides Credit Score

Lenders look at more than your credit score. They check how much you owe compared to your income, your down payment, and the stability of your job and pay.

Debt-to-Income Ratio (DTI)

Your DTI shows how much of your monthly income goes to debt payments. Lenders divide your monthly debt payments by your gross income to get this percentage. Many want a DTI below 43%, and some prefer it closer to 36% for the best rates.

To lower your DTI, pay down debts, avoid new loans, or increase your income. Lenders count mortgage, car loans, student loans, and minimum credit card payments in DTI. A lower DTI makes approval and better rates more likely.

Down Payment Amounts and Requirements

The down payment is the cash you pay upfront when buying. Conventional loans often require 3%–5% for qualified buyers, but 5%–20% is common to avoid mortgage insurance. FHA loans let you put down as little as 3.5% with the right credit score.

Larger down payments lower your loan amount and improve your terms. A 20% down payment usually lets you skip PMI. Some government-backed loans (VA, USDA) have low or no minimum down payment, but lenders still review your full finances.

Employment and Income Verification

Lenders check your job and income to be sure you can pay the mortgage. You’ll need to provide recent pay stubs, W-2s, tax returns, and possibly bank statements. Self-employed borrowers usually need two years of tax returns and profit-and-loss statements.

Steady, reliable income helps your approval odds. Short job gaps or drops in income can hurt your chances. Document raises, rental income, or alimony if you want them counted. Accurate, documented income speeds up the loan process.

How to Check and Improve Your Credit Before Buying

Check your credit reports, fix any errors, and focus on making on-time payments and lowering balances. Doing these things can improve your mortgage options and reduce the interest you pay.

How to Check Your Credit Score

Check your three credit reports at AnnualCreditReport.com at least once before applying for a mortgage. This site provides free reports from Experian, Equifax, and TransUnion. Review each report for errors in personal information, unfamiliar accounts, and late payment marks.

Check your credit scores on myFICO or directly with the bureaus. Lenders often use FICO scores, so myFICO shows you the score most lenders see. Note the score ranges and any recent changes so you can explain drops to your loan officer.

Tips to Improve Your Credit Fast

Start by making all payments on time, since payment history matters most to lenders. Set up autopay or reminders to avoid missing payments. Even a single missed payment can hurt your mortgage chances.

Lower your credit utilization by paying down balances or moving charges to cards with lower balances. Avoid opening new accounts before you apply for a mortgage. For a quick score boost, ask a creditor about a goodwill adjustment for old late payments you can document.

Paying Down Credit Card Balances

Focus on cards with the highest utilization first. Keep your balance below 30% of your limit, and aim for under 10% if possible. Making small extra payments each pay period reduces your balance faster than a single monthly payment.

If you have several cards, use the avalanche method (pay off the highest interest first) or the snowball method (smallest balance first) to stay motivated. Ask card issuers to increase your credit limits only if you won’t use the extra credit. 

Pay before the statement closing date so the lower balance is reported to bureaus.

Using a Co-Signer or Alternative Credit Data

A co-signer with stronger credit can help you qualify for a mortgage or a better rate. The co-signer’s credit and debt-to-income ratio matter, and they are legally responsible if you miss payments. Discuss risks and set clear repayment plans before proceeding.

If you lack a traditional credit history, some lenders accept alternative data like rent, utility, and phone payments. These records can show on-time payments and help you build a credible payment history for approval.

Strengthening Your Credit Before Buying

Good credit opens more doors than just mortgage approval — it gives you leverage for better rates, lower payments, and long-term financial stability. When you understand how credit influences lending decisions, you can take simple, confident steps to improve your score and buying power.
