Lenders price a home loan around your credit profile. The credit score for mortgage loan approval shapes both your interest rate and the size of your down payment. Even a 20-point bump can save thousands over the life of a loan.
This guide explains the score thresholds for the major mortgage programs, the formulas lenders use, and the steps that can raise your score before you apply. Plan ahead, and the math works in your favor.
How Mortgage Lenders Pull Your Score
Mortgage underwriters use the FICO Score 2, 4, and 5 models, one from each bureau. They take the middle of the three numbers, then use the lower middle if you have a co-borrower. This middle-of-three rule is unique to mortgages.
That means optimizing one bureau is not enough. Treat all three reports equally. The lowest-quality file becomes your effective score.
Minimum Credit Score for Conventional Loans
Conventional loans backed by Fannie Mae or Freddie Mac usually require a minimum of 620. Below that, options shrink quickly. To skip private mortgage insurance, you typically need 20% down regardless of score.
A score of 740 or higher unlocks the best conventional rates. The improvement between 680 and 740 can be sizable, often a full percentage point of rate. Run the numbers before locking in.
FHA Loan Score Requirements
FHA loans, insured by the Federal Housing Administration, allow lower scores. Borrowers with a 580 or higher can put down as little as 3.5%. Scores between 500 and 579 may qualify with a 10% down payment, though many lenders set their own higher floors.
FHA mortgage insurance applies regardless of down payment. That ongoing cost should factor into your decision, especially if your score is close to conventional territory.
VA and USDA Loan Score Standards
The VA loan program does not set a federal minimum score, but most lenders want 580 to 620. Eligible veterans, active-duty members, and surviving spouses can buy with no down payment. The funding fee replaces traditional mortgage insurance.
USDA loans for rural areas typically expect 640 or higher. Some lenders go lower with extra documentation. Both programs reward thicker, cleaner credit files.
What Else Lenders Check Beyond the Score
Underwriters look at debt-to-income ratio, employment history, and reserves. A great score with high credit card debt can still trigger denial. Most programs cap DTI in the low 40s, with some flexibility up to 50%.
Keep utilization low in the months before you apply. Avoid opening new accounts during the application window. New tradelines reset the average age of accounts and create inquiries lenders may question at closing.
How to Raise Your Score Before Applying
Start at least six months before house hunting. Pay every bill on time, since payment history is the largest factor. Bring revolving balances under 10% of limits where possible.
If you have a thin file, adding a starter product can build payment history fast. The Self Visa® Credit Card is one option that pairs with a credit-builder account, which may help borrowers add positive history while building modest revolving capacity. Terms and conditions apply, and qualification depends on Self’s account criteria.
Dispute clear errors on your reports. Roughly one in five reports contains a mistake, and removing one collection or one late payment that does not belong to you can move the score quickly.
What Each 20-Point Range Can Cost or Save
Small score moves carry real money. On a $400,000 loan, a 0.25% rate increase adds tens of thousands in lifetime interest. That is why pushing from 699 to 720 is worth the patience.

Timing Your Application Carefully
Avoid major credit moves in the 90 days before closing. New accounts, big purchases on cards, or even unpaid medical collections can shift your number. Lenders pull credit again right before funding, and surprises can derail the deal.
Firstcard recommends checking your three reports about six months before you apply. That gives time to clean up errors and let positive changes report through every bureau.

Frequently Asked Questions
What credit score do I need to buy a house?
Most conventional loans require 620, FHA loans accept 580 with 3.5% down, and VA or USDA loans typically expect 580 to 640. The best rates usually start around 740. Aim higher when you can, since each tier saves real money over the loan.
Can I get a mortgage with a 600 credit score?
Yes, often through FHA financing. Some lenders will work with conventional files in the high 500s, but rates and fees climb fast. Boosting the score even 20 points can change the offer materially.
How long does it take to raise a credit score for a mortgage?
Utilization fixes can show up within one billing cycle. Removing errors and adding positive payment history typically takes three to six months to move the score meaningfully. Plan your timeline backward from your target close date.
Do all three credit bureau scores need to be high?
Lenders use the middle of three FICO scores per borrower. The middle one matters most, but cleaning all three reports is smart since you cannot predict which two will fall above the middle. Treat the lowest report as your weakest link.
