Should You Pay Off Debt Before Buying a House?
In summary: When debt is charging you interest, like a typical credit card balance, paying it off may do more for you than putting the same money toward a bigger down payment. As an illustration, at recent average rates, $5,000 toward a down payment lowers a mortgage payment by about $34 a month, while the same $5,000 left on a credit card costs about $92 a month in interest. Paying a balance off completely also removes its payment from your debt-to-income ratio. Two things to watch for: make sure you still have enough left for closing costs and reserves, and know that paying off and closing an account can briefly shift your credit mix.
You’ve got some extra cash, you’re planning to buy a house, and you’re trying to decide where it does the most good. Put it toward the down payment, or use it to pay something off first?
A lot of advice answers half of this question. It’ll tell you that debt hurts your ratio, or that a bigger down payment lowers your payment, and leave you to compare the two yourself. Here’s the comparison, with numbers.
Should You Pay Off Debt or Save for a Bigger Down Payment?
Say you’ve got $5,000 to spare and you’re deciding between paying toward a credit card and putting it toward a bigger down payment.
The comparison really comes down to one thing: which rate is higher, the interest on your debt or the rate on your mortgage? Whichever one is, that’s the one costing you more to carry — and it’s usually the better place to put extra cash. Paying off debt has a bonus a bigger down payment doesn’t: it can also lower your debt-to-income ratio, which is something lenders look at closely. Here’s what that looks like with real numbers.
Toward the credit card, if that $5,000 is sitting on a card charging interest, you’re paying for it. The Federal Reserve’s G.19 survey put the average rate on credit card accounts (those that carry a balance) at 22.15% in the second quarter of 2026. At that rate, $5,000 in debt costs about $92 a month in interest alone, before you’ve made a dent in what you actually owe.
If that $5,000 is enough to pay the balance down to zero, it does more than save you interest. It also removes the card’s minimum payment from your debt-to-income ratio entirely, rather than just shrinking it, and it can raise your credit score within a statement cycle or two, since credit utilization is recalculated from your current balance. DTI and getting a mortgage covers how lenders calculate the ratio that includes your new mortgage payment. A partial payment may still help on all three counts, just by less, since the balance and the minimum only shrink instead of disappearing. The DTI calculator will show you both effects with your own numbers.
Toward the down payment instead, on a $250,000 home where you were planning 20% down, that same $5,000 shrinks the loan from $200,000 to $195,000. At a 7.28% rate — Freddie Mac’s national average for a 30-year fixed-rate mortgage as of October 1, 2026 — that extra $5,000 lowers your monthly payment by about $34. It trims your mortgage payment a little, which also trims your debt-to-income ratio a little, but it doesn’t remove anything from the ratio the way a full payoff does. This example assumes 20% down, so there’s no private mortgage insurance in the math. If you’re putting down less than 20%, extra money toward the down payment can also lower or remove mortgage insurance, which may strengthen the case for the down payment route more than this example shows. (Rates move week to week, so check Freddie Mac’s current average before relying on this comparison for a specific decision.)
So on both counts — interest saved and ratio moved — paying off the debt often comes out ahead, as in this example. That’s the case for debt with a real interest rate attached. It’s a different question for debt you’re already paying off at 0%, which we’ll get to.
Will Paying Off Debt Leave You Short at Closing?
Paying off debt stops being the obvious right answer once it would leave you short at closing.
Your mortgage needs more than your down payment. How to save for a down payment when money is tight covers the full target, including closing costs, which typically run 2% to 5% of the purchase price, according to Freddie Mac. Beyond that, many loans expect you to show reserves — extra funds left over after closing — as one of the things that Fannie Mae weighs favorably against a higher debt-to-income ratio. Reserve requirements vary by loan program, lender, and borrower profile, so a mortgage loan officer can tell you what applies to you.
So before you send $5,000 to a credit card, work out whether you still have what you need for closing costs and reserves once it’s gone. If sending the full $5,000 would leave you short, some people choose to pay off less than that, though a partial payoff may only modestly lower your ratio, depending on the type of debt. Paying off debt that leaves you unable to close may not get you any closer to the house.
Does Paying Off Debt Hurt Your Credit Score Before Buying a House?
Paying off debt affects your credit score in two different ways, and the effects aren’t both positive.
Paying down a balance helps your utilization, often quickly. Credit utilization is recalculated from your current balance, so a lower balance can show up in your score within a statement cycle or two.
But paying off a loan entirely, and closing the account, is a different move than paying down a balance. Length of credit history makes up 15% of a FICO score, and it’s based on the age of your accounts, including closed ones. FICO has addressed this directly: closing an account doesn’t shorten your credit history, because a closed account keeps counting toward it for as long as it stays on your report — generally 10 years for an account in good standing. Paying off a car loan doesn’t erase its age from your file the moment it’s closed.
What a payoff can still do is shift your credit mix, a smaller factor that makes up 10% of a FICO score. Scoring models give some credit for a mix of loan types: installment loans, like a car or a mortgage, and revolving credit, like cards. Paying off your only installment loan and closing it can nudge that factor slightly, even though your actual payment history and utilization improve. It’s typically a minor effect next to what paying off the debt does for your interest cost and your ratio, but it’s worth knowing so a small, temporary dip doesn’t catch you off guard.
One account to think twice about closing: if you’re thinking about closing a credit card you’ve had for a long time, even one with a zero balance, guidance often suggests holding off until after your mortgage closes. The immediate effect is losing its available credit, which can raise your utilization on the cards that are left — the age effect only shows up years later, once the closed account eventually drops off your report. Why is my credit score going down covers this and a few other moves that cost more than they seem to.
How Should You Pay Off Debt Before Applying for a Mortgage?
If you’re moving money to pay something off before you apply, the timing and the paper trail both matter.
Paying off debt earlier tends to keep things simpler. Lenders re-check your application for new debt and significant changes right up until closing. DTI and getting a mortgage covers what that means for taking on new debt. The same logic favors addressing old debt early: a payoff that happens well before you apply is simply part of your financial history by the time anyone’s looking at your file. A payoff that happens mid-application, by contrast, can raise questions about where the money came from.
Large, unexplained deposits can get flagged. Say a sum of money lands in an account you’ll also use for your down payment or reserves — a gift, a transfer, a payout — and you plan to use part of it to pay off a debt. If a lender sees that depositon the bank statements you use to verify your funds and you’re buying rather than refinancing, they’ll generally want to know where it came from. FHA, VA, and other loan programs have their own rules, which can differ. Under Fannie Mae’s guidelines for conventional loans, a deposit counts as large if it’s more than half your qualifying monthly income for the mortgage you’re applying for, which on $6,000 a month is any single deposit over $3,000.
A deposit with an obvious source on the statement, like a paycheck or a transfer from an account you’ve already verified, doesn’t need extra explanation. A large cash deposit, or a transfer from an account the lender hasn’t seen, generally does. What you do with the money afterward, including paying off a debt, isn’t the issue. Where it came from is. Because documentation rules vary by lender and program, ask your loan officer before moving any large sums.
Keeping a paper trail can help if the money comes from somewhere unusual. A gift from family, the sale of something valuable, or a payout from an account you haven’t shown the lender: any of these can work, but they go more smoothly if you can show where the money came from before you’re asked.
What If Your Debt Is Too Big to Pay Off Before You Apply?
Everything above assumes you’re choosing between two places to put money you already have. Sometimes the debt itself is bigger than that.
If your monthly minimum payments are large enough that there’s little left over to pay down balances or save at all, the math above doesn’t really apply, because there’s no spare $5,000 to choose a destination for. How long will it take before I can buy a house covers what happens when debt is the slowest of the three things standing between you and a mortgage, and it’s worth reading if that’s closer to your situation. If the minimum payments themselves are the obstacle, you can explore your options at no cost to see how you could reduce what you owe and get out of debt faster than making minimum payments alone would get you there.
Should You Pay Off a 0% Balance Before Buying a House?
There’s one exception to the comparisons above: debt you’re not paying interest on.
A 0% promotional balance doesn’t cost you anything to carry month to month, but it still comes with a required minimum payment, so it still counts toward your debt-to-income ratio, and paying it off can still help your application. There’s no interest being saved, though, so the comparison in the first section doesn’t apply. It’s worth checking when the promotional period ends: paying it off before that date avoids the jump to a regular rate, and paying it off before you apply still helps your ratio either way.
An informal loan from a family member is a different story, and it’s worth being cautious here. Lenders generally want any borrowed money disclosed, and whether an informal loan with no set payment schedule actually gets counted toward your ratio can depend on the lender. There’s a separate question if that same money is the source of your down payment: expect the lender to ask whether it’s a gift or a loan, since a documented loan comes with a repayment obligation that has to be factored into your file in a way a gift doesn’t.
Final Words
When the choice is between a bigger down payment and paying off debt that’s actually costing you interest, the debt payoff may help you come out ahead twice: once on the interest you stop paying, and again on how much further it moves your mortgage application. The two exceptions are debt you’re not paying interest on, where only the ratio benefit applies, and money you’ll need at closing, which shouldn’t go toward either option until you know your target.
Many people find it helpful to pay off debt early enough that it’s simply part of their history by the time they apply, to keep a record of where any large sums of money came from, and to hold off closing a long-held account even once its balance is at zero.
Frequently Asked Questions
If the debt is charging you interest, like a typical credit card balance, paying it off may do more for you than a bigger down payment does. As an illustration, $5,000 toward a typical down payment lowers a mortgage payment by about $34 a month, while the same $5,000 left on a credit card at the Federal Reserve’s most recent average rate of 22.15% costs about $92 a month in interest. Paying off the debt also removes its entire payment from your debt-to-income ratio, while a bigger down payment only trims the mortgage payment slightly.
Paying off a car loan may not hurt your credit score the way people often assume, though a small, temporary dip is possible. Length of credit history makes up 15% of a FICO score, and FICO’s own guidance confirms that closed accounts generally keep counting toward as long as they stay on your report (generally 10 years for an account close in good standing)., so paying off and closing a loan doesn’t erase its age from your file. The more likely effect is a small shift in your credit mix, since you’d have one less active installment loan, but it’s minor next to what paying off the debt does for your interest cost and your ratio.
A large deposit used to pay off debt can cause problems if the lender can’t tell where the money came from. On a conventional loan, Fannie Mae’s guidelines generally call for documentation of any single deposit larger than half your qualifying monthly income for the loan. FHA, VA, and other loan programs set their own rules. A deposit with an obvious source, like a paycheck or a transfer from an account the lender has already verified, doesn’t need extra explanation. Paying a debt down from that money afterward isn’t the issue; showing where the money came from is.
Guidance often says to hold off on closing a credit card before you apply for a mortgage, even once you’ve paid it off to zero. Closing it removes its available credit right away, which can raise your utilization on the cards you keep open, and paying the balance to zero while leaving the account open gets you that credit-score benefit without the downside. The length-of-history effect isn’t a reason to worry either way: a closed account in good standing keeps counting toward your history for years, and it only stops once it eventually falls off your report, but there’s no reason to risk the utilization hit to find that out.
Paying off a 0% balance can still help your debt-to-income ratio, even though it isn’t costing you interest. The ratio typically counts the monthly payment, not whether the balance carries a rate, so paying it off still removes that payment from your application. The interest-savings comparison in this piece doesn’t apply to 0% debt, since there’s no interest to save, but check when the promotional rate ends if you don’t pay it off, since the rate afterward won’t be 0%.
It’s common practice to keep enough in reserve to cover your closing costs, which typically run 2% to 5% of the purchase price, plus whatever reserve your loan expects you to show afterward. Reserves are one of the things that can help a lender approve a higher debt-to-income ratio, so draining them to pay off a debt can cost you more than it saves. If paying off a balance in full would leave you short at closing, a partial payoff is one option, though it may only modestly lower your ratio, depending on the type of debt. It’s also worth keeping a small cushion beyond what the lender requires, so the first repair or surprise expense after you move in doesn’t land on a credit card. Reserve requirements vary by program and lender, so ask a mortgage loan officer what applies to you. The emergency fund calculator can help you size that.
