Key takeaways

  • The minimum credit score required for a conventional loan is 620, while other mortgages require anywhere from 500 to 700.
  • A higher credit score usually translates to lower interest rates.
  • Paying bills on time, keeping credit card balances and number of accounts low and becoming an authorized user on another’s account can improve your credit score.

Your credit score is one of the primary factors mortgage lenders consider when you apply for a loan. If your score needs work, there are steps you can take to improve it before you apply. Here’s everything you need to know about how to improve your credit score to buy a house.

Mortgage credit score requirements

The minimum credit score needed to qualify for different types of mortgages ranges.

Type of Loan Minimum Credit Score
Conventional 620
Jumbo 700
FHA 580 (or 500 with 10 percent down)
VA 620 (VA doesn’t require a minimum credit score, but lenders do)
USDA 640

Still, it’s best to have the highest credit score possible before you apply for a mortgage. In fact, the average credit score for a borrower getting a purchase loan is 737, according to Optimal Blue’s March 2024 Originations Market Monitor report.

Why is a higher credit score beneficial when applying for a mortgage?

The higher your credit score, the better chance you’ll have of being approved for a mortgage. This is because lenders want to ensure you’ll repay the owed amount, and your credit score is one factor they look at to determine your risk level. A higher credit score will usually get you a lower mortgage rate as well.

Even a small difference in the mortgage rate you get affects your monthly payment and overall loan cost. For example, using Bankrate’s mortgage calculator, let’s say you buy a $300,000 house with a 6.875 percent fixed rate and put 3 percent down. Your monthly payment would be about $2,176. If you had a 7 percent fixed rate, your monthly payment would be $2,200. While the difference looks small at first, over the course of a 30-year mortgage, you’d save over $8,000.

How to improve your credit score before getting a mortgage

  1. Check your credit reports and scores
  2. Pay all your bills on time
  3. Reduce your credit card balances
  4. Avoid opening new accounts
  5. Get help from a responsible credit user

1. Check your credit reports and scores

Get a copy of your credit report from each major credit bureau (Equifax, Experian and TransUnion) through Aside from reviewing your scores, make sure there are no mistakes, especially regarding late payments or closed accounts. If there is an error, contact the bureau to dispute it as soon as possible.

2. Pay all your bills on time

To improve your credit score for a mortgage, keep all your accounts in good standing. Missing a payment can lower your credit score, and late payments can stay on your report for up to seven years. If you’re currently late on a payment but still within the grace period, contact the creditor right away to see if you can get things back on track (and the late charge erased). If you do have a late payment on your record, strive to make payments on-time moving forward.

3. Reduce your credit card balances

Your credit utilization ratio is the amount you owe against your total available credit, and it accounts for 30 percent of your score. The lower the ratio, the better. As a rule of thumb, if your utilization is over 30 percent, work to pay down those balances so you’re under that threshold.

4. Avoid opening new accounts

Applying for new credit will affect your score. If you can, avoid opening new credit card accounts or taking out more loans before you apply for a mortgage. Follow this tip during the application and mortgage underwriting process as well. By the same token, don’t close any old accounts, either — this can raise your utilization ratio and have a negative effect on your score.

5. Get help from a responsible credit user

If you’re a younger first-time buyer, you might not have a very long credit history. One way to improve credit to buy a house: Become an authorized user on a parent’s or relative’s credit card. The primary cardholder (your parent or relative) will continue to make the payments, but you’ll benefit from the positive payment history.

What factors determine your FICO credit score?

There are several categories of your credit history that inform your current score. Some things affect your score more than others. According to Equifax, one of the major credit bureaus, your FICO score is determined using a formula that roughly looks like this:

  • On-time payment history (35 percent of score)
  • Amount of debt (30 percent of score)
  • Length of total credit history (15 percent of score)
  • Number of new accounts (10 percent of score)
  • Type of credit utilized (10 percent of score)

Credit bureaus tend to assign “good debt” and “bad debt” labels to your current debt. Home loans and other debt that can increase your financial worth in the long term are considered good. Credit card debt and other revolving accounts that don’t go toward a valuable asset are more likely to decrease your FICO score.

Credit Good
The national average FICO score as of October 2023 is 717, down one point from July 2023, according to FICO.

How quickly can you improve your credit score?

Items like a missed payment or bankruptcy will stay on your credit report for up to seven years. However, they may not make a significant impact on your credit score after a few years.

If you want to improve your credit score fast enough to buy a house — say, in a few months — the best thing you can do is pay down current debt and avoid opening new accounts. While you can’t immediately change the length of your credit history or erase missed payments, reducing the balance on your revolving accounts can make a big difference within a month or two. This is especially so if your credit utilization ratio is 30 percent or less.

If you can increase your credit limits on card accounts, that can help within a month or so, too — it’s improving the credit utilization ratio from the opposite end.

Can you get a mortgage with bad credit?

It’s still possible to get a mortgage with bad credit or less-than-ideal credit. However, the lower your score, the harder it will be to secure a mortgage. For instance, you can get an FHA loan with a credit score as low as 500, but you’ll need to put 10 percent down. If you can get your score up to 580, you can get an FHA mortgage with 3.5 percent down.

Know also that some lenders have stricter requirements, so it’s smart to compare lenders who specialize in low-credit-score mortgages.
