How to Improve Your Credit Score Before Applying for a Mortgage

Your credit score has a bigger impact on your mortgage than almost any other single factor. A 40-point difference can move you into a better pricing tier, translating to a lower interest rate, lower monthly payment, and tens of thousands of dollars in savings over the life of the loan.

How Lenders Use Credit

Mortgage lenders pull a tri-merge credit report (Equifax, Experian, TransUnion) and use the middle of the three FICO scores. Most conventional pricing tiers update in roughly 20-point bands, 620, 640, 660, 680, 700, 720, 740+. Each tier you climb typically improves your rate or reduces your closing costs.

1. Pay Down Revolving Balances

Credit-card utilization is the single most actionable lever in 30–60 days. Your score weighs both overall utilization (total balances divided by total limits) and per-card utilization. Aim to keep both under 30%, ideally under 10%.

Don't close the cards after paying them down, closing reduces total available credit and can raise utilization on the remaining cards.

2. Don't Open New Accounts

Every new credit application creates a hard inquiry and lowers the average age of your accounts. Both hurt your score temporarily. In the 6 months before you apply for a mortgage, avoid new credit cards, store financing, car loans, or buy-now-pay-later accounts.

3. Catch and Dispute Errors

About 1 in 5 credit reports has an error significant enough to affect your score. Pull your free reports at AnnualCreditReport.com and check for accounts you don't recognize, balances that look wrong, or late payments that weren't actually late. Disputes can resolve in 30 days.

4. Get Added as an Authorized User

If you have a family member with a long-standing, low-utilization credit card in good standing, being added as an authorized user can boost your score quickly, especially if your own credit history is thin.

5. Pay Every Bill On Time (Even the Small Ones)

Payment history is the largest component of your FICO score. Even one 30-day late payment can drop your score significantly and stays on your report for 7 years. Set up autopay for at least the minimum on every account.

Credit Myths to Skip

Closing old cards doesn't help. Paying off and immediately closing accounts can hurt utilization. "Rapid rescore" services are real but typically only useful in the final stretch before closing. And there's no magic credit-repair company that can do anything you can't do yourself for free.
