What credit score do you need to buy a house?

Having a high credit score makes it easier to qualify for large loans, such as a mortgage, and receive low interest rates. However, depending on your circumstances, you might not be able to quickly improve your credit score before you need to buy a home. So knowing the minimum credit score requirements can be helpful for prospective homebuyers.

The quick answer is that having a credit score of 620 or higher is helpful, but you may still be able to buy a house with a score as low as 500. But, there’s a lot of nuance you should understand beyond that. Read on and we’ll explain what credit score is needed to buy a house based on the type of mortgage you’re applying for (and what types of scores matter).

Which credit scores do mortgage lenders use?

Before we can get to the minimum score requirements for a mortgage, it’s important to identify which credit scores matter. There are numerous scoring models on the market.

FICO and VantageScore are competing credit scoring agencies, and they both develop and sell credit scoring models for lenders. Combined, they offer dozens of credit scores, which is one reason your credit scores can vary widely depending on where you check your scores.

When you apply for a mortgage, most lenders request a special report that includes information from all three of your credit reports (from bureaus Equifax, Experian, and TransUnion) and a FICO score based on each report. The FICO score models are commonly referred to as Classic FICO Scores and individually named as follows:

  • FICO Score 2—Experian/Fair Isaac Risk Model v2

  • FICO Score 5—Equifax Beacon 5

  • FICO Score 4—TransUnion FICO Risk Score 04

Once the lender has all three scores, they’ll often use the middle score to help determine your eligibility and interest rates. Or, if you only have two scores, the lower score. If you’re jointly applying with someone else, the lower score is what matters. But sometimes, the lender uses the borrowers’ average median score.

Lenders generally use these types of scores and these rules to comply with Fannie Mae and Freddie Mac underwriting guidelines. The two government-sponsored entities (GSEs) purchase many mortgages from lenders, and other investors might prefer buying mortgages that were assessed using the guidelines.

However, lenders can use other credit scoring models and rules if they want. And they might break with convention if they keep the loan on their books—a “portfolio” loan—rather than sell it to a GSE or investor.

Mortgage lenders will start using newer credit scores in 2024

The Federal Housing Finance Agency (FHFA) supervises and regulates the GSEs, and it announced a change to the required credit score models in October 2022.
