How to Improve Your Credit Score Before Buying a Home

Your credit score is one of the biggest factors in determining your mortgage rate. Even a small improvement can save you tens of thousands over the life of your loan. Here's what actually moves the needle.

How Much Does Your Credit Score Matter?

The difference between a 680 and a 740 credit score on a $300,000 mortgage can mean a rate difference of 0.5% or more. On a 30-year loan, that translates to roughly $30,000 in extra interest paid.

The Five Factors That Determine Your Score

1. Payment history (35%) — Pay every bill on time, every time
2. Credit utilization (30%) — How much of your available credit you're using
3. Length of credit history (15%) — Older accounts help
4. Credit mix (10%) — Having different types of credit
5. New inquiries (10%) — Applying for new credit

The top two factors — payment history and utilization — account for 65% of your score. That's where to focus your effort.

Quick Wins That Can Boost Your Score

Pay Down Credit Card Balances

This is the single fastest way to improve your score. Aim to get each card below 30% of its limit — below 10% is even better.

If you have a $10,000 credit limit and a $4,500 balance, paying it down to $2,500 (25%) can improve your score noticeably within a billing cycle.

Become an Authorized User

If a family member has a credit card with a long history and low utilization, being added as an authorized user can boost your score. You don't even need to use the card.

Dispute Errors on Your Credit Report

Pull your free reports from annualcreditreport.com and look for:

• Accounts that aren't yours
• Late payments that were actually on time
• Incorrect balances or credit limits
• Closed accounts listed as open (or vice versa)

Disputing errors is free and can result in a meaningful score increase if you find legitimate mistakes.

Don't Close Old Cards

Even if you don't use an old credit card, keeping it open helps your credit utilization ratio and average account age. Cut up the card if you need to — just don't close the account.

What to Avoid Before Applying

In the months leading up to your mortgage application:

• Don't open new credit accounts — Each application creates a hard inquiry
• Don't make large purchases on credit — Keep utilization low
• Don't co-sign for anyone — Their debt becomes your debt on paper
• Don't change jobs if possible — Lenders prefer stable employment history

What If My Credit Isn't Perfect?

You don't need a perfect score to buy a home. FHA loans accept scores as low as 580 with 3.5% down. Even scores in the 500s can qualify with a larger down payment.
