What Credit Score Do You Need to Buy a House?

The credit score required to buy a house is not a single number. It depends on the type of loan you are applying for, the lender's own requirements within that loan type, and how much down payment you are making. FHA loans accept scores as low as 580. Conventional loans typically require 620 as a minimum. And the most competitive mortgage rates, regardless of loan type, are reserved for borrowers with scores of 740 or above.

Understanding the credit score landscape in mortgage lending helps you assess your current position accurately, identify which loan types you qualify for today, and determine whether spending a few months building your score before applying would produce meaningfully better terms. For many buyers, the financial difference between borrowing with a 680 score versus a 740 score is substantial enough to justify delaying the purchase.

This guide maps the credit score thresholds for each major loan type, explains how scores affect mortgage rates through the specific pricing tiers lenders use, and identifies the most effective strategies for improving your score before a mortgage application.

Credit Score Requirements by Loan Type

FHA loans have the most accessible credit score requirements of any major loan program. The minimum score for a 3.5 percent down payment is 580. Borrowers with scores between 500 and 579 may qualify with a 10 percent down payment. FHA lenders frequently add their own overlay requirements above these minimums, often requiring 620 or 640 in practice.

Conventional loans backed by Fannie Mae and Freddie Mac have a minimum score of 620, though their Automated Underwriting Systems apply loan-level price adjustments that significantly increase the effective cost of conventional loans at scores between 620 and 680. The most competitive conventional pricing begins at 720 and reaches its best level at 760.

VA loans have no official minimum credit score requirement set by the VA, though individual VA-approved lenders typically require a minimum of 580 to 620. The VA guarantee reduces lender risk enough that VA-approved lenders accept lower scores than they would for conventional loans. USDA loans require a minimum of 640 for the automated approval process.

How Credit Score Affects Your Mortgage Rate

Mortgage rates are priced in tiers based on credit score, with meaningful differences between tiers that translate to thousands of dollars in total interest. The tiered pricing comes from loan-level price adjustments applied by Fannie Mae and Freddie Mac to conventional loans, which affect both the rate and the cost of mortgage insurance.

The rate difference between a 680 and a 760 score on a conventional loan can be 0.5 to 0.75 percent. On a $350,000 loan at a 30-year term, 0.5 percent equals approximately $35,000 in additional total interest over the loan's life. This is the financial case for taking several months to improve your score before applying if you are near a tier boundary.

FHA rates are less tiered by credit score because the FHA insurance protects the lender, but higher-score FHA borrowers still receive better rate offers because individual lenders add their own risk pricing on top of the FHA guarantee requirements.

Strategies for Improving Your Score Before Applying

Reducing credit card balances is the fastest and often highest-impact credit score improvement strategy. If your cards are above 30 percent utilization, paying them below 10 percent can produce a score improvement of 20 to 50 points within a single billing cycle. Pay before the statement closing date to ensure the lower balance is reported.

Review all three credit reports for errors before applying for a mortgage. FHA, conventional, and VA lenders pull bureau-specific FICO scores from all three bureaus and typically use the middle score of the three. An error at a single bureau that lowers that bureau's score can produce a lower middle score even if the other two are strong. Dispute errors at least 60 to 90 days before you plan to apply to ensure the dispute resolves before the mortgage inquiry.

Avoid any new credit applications, large purchases on existing cards, or significant financial changes in the 90 days before a mortgage application. New accounts lower average account age, hard inquiries can lower the score slightly, and large new charges can spike utilization in ways that take months to resolve.

Minimum Score vs Optimal Score: The Financial Calculation

Meeting the minimum credit score to qualify for a loan does not mean you are getting the best available terms. The financial difference between qualifying and getting the best rate can be enormous over 30 years. For many buyers, spending three to six months below a tier threshold improving their score is worth the delay.

The calculation is specific: determine your current credit score tier and the rate associated with it, then determine the next higher tier's rate. Calculate the monthly payment difference and the total interest difference over 30 years. Compare this to the number of months of delay needed to reach the higher tier. If the interest savings exceed the cost of delay (continued rent payments, any additional savings during the delay period), the delay is financially rational.

Not all buyers have the luxury of delay. Lease expirations, family situations, and market conditions may require purchase timing that does not align with the optimal credit-building timeline. In these cases, qualifying with your current score and planning a refinance once the score improves and equity builds is a reasonable approach.

Final Thoughts

The credit score you bring to a mortgage application directly determines both what loan types are available to you and what rate you pay on those loans. The financial stakes are high: the difference between a marginal score and an excellent score can be tens of thousands of dollars over the life of a 30-year mortgage.

Know your current score and which tier you fall into. Identify specifically what is holding your score below the next tier threshold. Take targeted action to address those factors in the three to six months before your planned application. Verify your credit reports for errors and dispute anything inaccurate.

Arrive at the mortgage application with the strongest credit profile you can achieve given your timeline. The rate you lock in will follow you for decades.
