For most conventional mortgages, lenders want you to have a credit score of at least 620. However, the minimum score varies by loan type.
To buy a house, you may need a credit score of at least 500, but it will depend on the type of mortgage loan you’re applying for and the lender. While its possible to get a mortgage with bad credit, you typically need good or exceptional credit to qualify for the best terms.
Read on to find out what credit score you need to buy a house and how to raise it before you apply for a mortgage.
If your FICO score is 645, you have fair credit. This means you can still buy a house, but you may face some problems. The lowest score needed for a mortgage depends on the program, but lenders usually want scores of 620 or higher. With some planning and research, a 645 FICO score can still help you become a homeowner.
What Credit Score is Considered Fair?
The most commonly used credit scoring model, FICO, ranks credit scores from 300 to 850 Scores are grouped into the following ranges
- 800-850: Exceptional
- 740-799: Very Good
- 670-739: Good
- 580-669: Fair
- 300-579: Very Poor
So a 645 FICO score falls into the fair range. It’s below the average credit score of 711 for U. S. consumers. A 645 is still a good score, but it won’t get you the best loan rates and terms.
Is 645 a Good Credit Score to Buy a House?
Whether a 645 credit score is good enough depends on a few factors
- Type of mortgage – Government-backed loans like FHA, USDA, and VA have more lenient credit requirements than conventional mortgages.
- Down payment – A larger down payment can help compensate for a lower score.
- Debt-to-income ratio – Lenders look at your total monthly debt obligations along with your score.
- Individual lender requirements – Overlay guidelines may impose higher score minimums.
For most mortgages, a 645 is good enough, but you may need to put down more money and/or pay a higher interest rate. Conventional loans in particular may be challenging to obtain.
What is the Minimum Credit Score to Buy a House?

So government-backed loans provide more flexibility for lower scores. With FHA in particular, you may be able to buy with a 645 FICO and 3.5% down payment.

Down payment size, debts, and individual lender overlays also play a role. With preparation and shopping around to find a lender willing to approve your application, homeownership can still be within reach.
How to Improve Your Credit Before Getting a Mortgage
Whether youre thinking about buying a home soon or further down the road, its worth spending some time getting your credit ready before you officially begin the process. Here are actions you can start taking now, some of which can improve your credit score relatively quickly.
Avoid Applying for New Credit
Applying for and opening new credit accounts not only impacts your credit score but can also increase your DTI. As a result, many mortgage lenders prefer that you dont apply for credit in the months leading up to your mortgage application and also throughout the mortgage process.
If you need to apply for credit, prepare to explain your reasoning. Even with a good reason, however, it could impact your approval odds.
Cutting back on your spending can boost your savings and also help keep your credit utilization rate down. Take a look at your budget and identify areas where you can reasonably pare back on your expenses as you work to prepare for your mortgage application.
