Keep credit card utilization in the single digits, on each card and across all of them, and under 30% at the very most. Pay balances down before the statement closes so the lower figure is what the mortgage lender pulls.
Weeks before you apply, your cards can look maxed out because of a statement balance you plan to pay anyway, or because your report shows a balance or limit that is simply wrong. The first is a timing problem a payment fixes. The second is an error, and the Fair Credit Reporting Act gives you a way to challenge it.
Aim for single-digit credit utilization before you apply for a mortgage
People with 850 FICO Scores run an overall utilization rate around 4.1% (myFICO, 2026). Under 10% is ideal, and it is where the highest scores tend to sit. Under 30% is the widely cited threshold lenders like to see, so treat 30% as the ceiling and single digits as the goal.
Utilization is one of the largest factors in a credit score, generally second only to payment history. It is about 30% of a FICO score. Unlike payment history, which builds slowly, it updates every time your balances are reported, usually monthly. That is why you can move it in weeks.
How do you calculate your credit utilization ratio for a mortgage?
Divide the balance each card issuer reports by that card’s credit limit, then add all your revolving balances and limits and divide again. Only revolving accounts such as credit cards count. Installment loans like an auto loan or a mortgage do not.
Say, hypothetically, you carry $2,000 across cards with $20,000 in combined limits. That is 10% overall. If $1,800 of it sits on one card with a $2,000 limit, that card reads 90%, though the overall number looks fine. Every figure in this example is hypothetical.
Your score uses the balance the issuer reports, which is often your statement balance and not what you owe today. Even if you pay in full every month, a high statement balance still shows as high utilization.
Why does one maxed-out card hurt a mortgage application?
Scoring models look at each card’s utilization as well as the total, so one card near its limit can pull a score down even when the overall ratio looks low. Experian says a card at 100% hurts your score even if your overall utilization is relatively low (Experian, 2025).
So an overall 8% is not enough if one card sits at 90%. Pay down the card nearest its limit first, then bring every card into single digits.
When should you pay down credit cards before a mortgage application?
Pay before each card’s statement closing date. Equifax says issuers should report monthly, preferably on the billing cycle date, which for credit cards is usually the statement date (Equifax). Equifax also advises starting to pay balances down a few months before you apply for a loan.
Here is the order that works:
- Find the statement closing date on every card.
- Pay each balance down before that date.
- Check that the next statement shows the lower balance.
- Give it one to two billing cycles, so the lower figure is already on file when your lender pulls.
What else do mortgage lenders check besides credit card utilization?
Lenders also weigh your debt-to-income ratio, which tests whether you can afford the monthly payment, along with your credit score and history. For loans run through Desktop Underwriter, the maximum debt-to-income ratio is 50% (Fannie Mae Selling Guide, 2026).
Income is not in your score, and lenders look at it separately. A single-digit ratio helps the score side of your file. It does nothing for the payment-to-income side, so check both before you apply.
What can you do when a wrong balance or limit raises your utilization?
A balance, limit or account that is wrong on your report is an error you can dispute in writing with each bureau, and the bureau must investigate. Under Section 611 of the Fair Credit Reporting Act (15 U.S.C. 1681i), it has 30 days from receiving your dispute, and 45 if you send relevant information during that window.
Look for a limit reported lower than your real one, or a balance you already paid that still shows. Dispute only what is actually inaccurate, and attach statements as evidence. Keep your dispute record: what you disputed, when the bureau received it, and what came back.
Timing matters for a mortgage. While a bureau investigates, the account can carry a note that the item is disputed, and lenders pulling your report can see it. Some mortgage programs require dispute remarks to be resolved before closing. Resolving an error takes at least the 30-day window, so start early and tell your loan officer.
Bring single-digit ratios and a correct report to your lender
The number to bring is not the 30% everyone repeats. It is single digits on every card, reported before the statement closes. If your ratio will not come down because the report itself is wrong, that is an error to dispute with the bureaus, and a number you never have to live with.
What credit-dispute tools cost for a mortgage buyer cleaning up reports
Dispute tools run from free to $139.95 a month, and federal law bars credit repair companies from charging you before they help you (the FTC’s consumer advice, 2026). Before you pay anyone to deal with a wrong balance or limit, compare the price, who sends the letters and how many bureaus are reached.
CreditRefresh costs $49.99 a month with no setup fee and reaches all three bureaus, and Lexington Law runs $139.95 a month.

If you already paid for one of these and nothing changed, the complaints will sound familiar. Credit Karma shows a 1.1 on Trustpilot across 915 reviews, and 34 of its 197 most recent 1 and 2 star reviews, in its latest 200, say nobody answers. Dispute Beast shows 4.2 across 2091 reviews, and 21 of its 33 most recent 1 and 2 star reviews, in its latest 200, say they paid for months and nothing changed.
Lexington Law shows 3.2 across 624 reviews. Of its 134 most recent 1 and 2 star reviews in its latest 200, 79 raise the same paid-for-months complaint. Jennifer C. gave Lexington Law one star on Trustpilot on March 20, 2024: “Their policy read they would initially charge $14.95 but $99 was withdrawn from my account.”

Frequently Asked Questions
Should you leave a small balance on a card before applying for a mortgage?
Yes, on one card. Experian describes paying balances before the billing cycle ends but letting one card report a small balance, because a very low ratio scores better than no use at all (Experian, 2024). A zero balance is not penalized, but a small reported balance scores a little better.
Should you close a credit card before applying for a mortgage?
No. Closing a card takes its limit out of your total, and the CFPB says closing a card can raise your utilization ratio and lower your score (CFPB, 2025). Say, hypothetically, you carry $2,000 against $20,000 in limits, a 10% ratio. Close a $10,000 card and the same $2,000 sits against $10,000, which is 20%. If you carry no balances, the effect is minimal.
Should you open a new credit card to lower your utilization before a mortgage?
No. A hard inquiry happens when you apply for credit and a lender checks your file, and a new account also lowers your average account age right away. Pay down the cards you already have instead.
How long does high credit utilization stay on your credit report?
Experian says the damage from high utilization goes away once the bureaus hold your new, lower balances, and it puts the earliest effect at 30 days after the issuer reports the lower figure (Experian, 2023). Allow one to two billing cycles before your lender pulls your report.
Why is the score a mortgage lender pulls different from the free score in your app?
Mortgage lending runs on specific older FICO versions required in that market, while free apps and bank dashboards commonly show VantageScore because of licensing. Different models and bureaus return different numbers from the same file. Watch the range you are in, and ask your lender which score it will pull.
Does a credit limit increase help your utilization before a mortgage?
A higher limit lowers your ratio, since the same balance sits against more credit. Ask the issuer first whether the request involves a hard inquiry. An issuer’s own review of a current customer’s file is a soft inquiry, but an application for an increase can generate a hard one.
CreditRefresh reads your three reports for a wrong balance or limit and drafts the FCRA letter for each item, which you review and sign before anything is sent. Every plan comes with our 100% money-back guarantee.
