Quick answer: Pay each card below 30% of its limit, starting with any maxed-out card, keep all accounts open, and pay every bill on time. Avoid new credit until closing, and ask a loan officer how much to pay down to reach your target debt-to-income ratio.↗ Share on X

If you have credit card debt and want a mortgage, the best plan is usually this: pay your card balances down to below 30% of each card's limit (lower is better), keep every account open, make every payment on time, and do not open or close any credit while you are applying. Lenders care about two numbers above all: your credit score and your debt-to-income ratio. Credit card debt hurts both, but you can improve both in a few months if you follow a clear order of steps.

This article explains what lenders look at, what to pay first, what not to do, and how to time it all. Rules change between lenders and loan types, so talk to a loan officer or a HUD-approved housing counselor before you make big moves.

When you apply, the lender pulls your credit report and looks at your income and monthly bills. Three things matter most for card debt:

1. Your credit score. A higher score can mean a lower interest rate. Even a small rate difference adds up over 15 or 30 years.

2. Your credit utilization. This is how much of your card limits you are using. If your limit is $5,000 and you owe $2,500, your utilization is 50%. High utilization pulls your score down.

3. Your debt-to-income ratio (DTI). This is your total monthly debt payments divided by your monthly income before taxes. Lenders use the minimum payment on each card, not the full balance.

Here is a simple DTI example:

Each loan program has its own limits, and many lenders prefer a DTI well under the maximum. If your number is high, cutting card balances lowers your minimum payments, which lowers your DTI.

Pay off cards first or save for the down payment?

This is the hardest choice, and there is no single answer. It depends on where your money does the most good.

Think about it like this:

• If your utilization is very high (over 50%), paying cards down can raise your score and lower your DTI at the same time. That can help you qualify, or get a better rate.
• If your utilization is already low and your DTI is fine, extra money may help more as down payment or cash reserves.
• Never empty your savings completely. Lenders often want to see some money left after closing. You also need a cushion for repairs once you own the home.

A loan officer can run your numbers both ways. Ask them: "If I put $3,000 toward my cards instead of my down payment, how does that change my rate and my approval?" This question is free to ask, and the answer is specific to you.

Which card should you pay first?

When a mortgage is coming, the goal is not only to save interest. It is also to lower utilization fast. Use this order:

1. Any card that is near or over its limit. A maxed-out card hurts your score a lot. Bring it below 30% first, and below 10% if you can.

2. Cards with the highest interest rate. Once no card is near its limit, attack the most expensive debt.

3. Small balances you can pay off fully. Paying a card to zero lowers the number of cards with a balance, which can also help.

Keep paying at least the minimum on every card, every month. One late payment of 30 days or more can drop your score sharply and stay on your report for years. Set up automatic minimum payments today if you have not already.

What timing tricks help your score?

Most card companies report your balance to the credit bureaus once a month, usually on your statement closing date, not your due date. That means:

• If you pay your balance down before the statement closes, a lower number is reported.
• If you pay after the statement closes but before the due date, you avoid interest, but the higher balance may still show on your report.

Find your statement closing date on your bill or app. Make a large payment a few days before it. Do this one or two months before you apply.

Also plan for the lag. A payment you make today may take 30 to 45 days to show on your credit report. Start paying down debt at least two to three months before you want to apply.

What should you never do while applying?

These mistakes cause problems right before closing. Lenders often check your credit again shortly before the loan closes, so the rules last until you have the keys.

If you are tempted by a 0% balance transfer card, the timing matters. Opening one right before a mortgage application adds a new account and a hard inquiry. If you want one, ask your loan officer first, and try to do it many months before you apply, not weeks.

Should you get a debt consolidation loan first?

A personal loan that pays off several cards can lower your utilization because installment loans are scored differently from cards. It can also lower your interest rate.

But it has risks:

• It is a new account with a hard inquiry.
• The new monthly payment counts in your DTI.
• If you run the cards back up, you end up with more debt than before.

If you go this way, do it early, at least six months before you apply if possible, and keep the old cards open but unused. Again, ask a loan officer before you sign.

A sample three-month plan

Here is one way to organize the months before you apply. Adjust it to your situation.

Week 1

1. Pull your free credit reports from all three bureaus and check for errors.

2. List every card: balance, limit, interest rate, minimum payment, and statement closing date.

3. Set up automatic minimum payments on all cards.

4. Talk to a loan officer to get your current DTI and a target.

Weeks 2 to 8

1. Pay any maxed-out cards below 30% of their limit.

2. Put extra money on the highest-rate card next.

3. Cut spending on cards. Use debit or cash for daily costs.

4. Dispute any errors you found on your reports.

Weeks 9 to 12

1. Make large payments a few days before statement closing dates.

2. Check your score again after the new balances report.

3. Gather documents: pay stubs, tax returns, bank statements.

4. Apply when your utilization and DTI are where your loan officer said they should be.

What if your debt is too high to fix quickly?

Sometimes the honest answer is to wait. Buying a home with a payment you cannot afford, on top of heavy card debt, puts the home itself at risk.

Signs you may need more time:

• You can only make minimum payments on your cards.
• Your DTI is near or above the lender's limit even with the mortgage at the low end of your range.
• You have recent late payments.

In that case, a nonprofit credit counseling agency can review your budget and may offer a debt management plan. Look for agencies that are members of the National Foundation for Credit Counseling (NFCC). Be careful with companies that promise to erase debt for a fee; debt settlement can badly damage your credit right when you need it most.

Your next step

This week, write down every card you have with its balance, limit, and statement closing date. Divide each balance by its limit to find your utilization. Then call a loan officer or a HUD-approved housing counselor, share those numbers, and ask exactly how much you need to pay down to qualify for the loan you want. That one phone call turns a vague goal into a dollar amount and a date.

FAQ

Should I close credit cards before applying for a mortgage?

Usually no. Closing a card lowers your total available credit, which raises your utilization and can lower your score.

How long before applying should I pay down my cards?

Start at least two to three months before. New balances can take 30 to 45 days to show on your credit report.

Do lenders count my full card balance in my DTI?

Lenders generally use the minimum monthly payment on each card, not the full balance, when they calculate your debt-to-income ratio.

Who can review my situation for free?

A HUD-approved housing counselor or a nonprofit credit counseling agency can review your budget. A loan officer can also run your numbers before you apply.
