Credit card interest rates averaged more than 21% among borrowers who carried a balance in early 2026. Mortgage rates are generally much lower.
Turning that 21% rate into, say, sub-7% sounds like an easy decision, right?
Refinancing your mortgage to consolidate debt can make that possible. But the decision isn’t as easy as it looks. Rolling that debt into a lower-rate mortgage turns unsecured balances into a loan that uses your home as collateral, extends short-term balances across decades, and comes with closing costs that can run into the thousands. Here’s how to decide whether it’s a good idea for your situation.
How debt consolidation through a mortgage refinance works
Consolidating debt using your home equity often involves “cash-out” refinancing. With a cash-out refi, a new home loan replaces your current mortgage with a larger loan and may extend your repayment timeline. The loan is enough to pay off your current mortgage—and then some. You receive the remaining amount in cash and can use it to pay down your debts. This approach can offer a couple of potential advantages over a personal loan.
First, you’ll effectively roll multiple debts into your mortgage payment. While a personal debt consolidation loan can reduce the number of minimum payments you make, a cash-out refinance can leave you with only your mortgage payment for the debts you consolidate.
Also, cash-out refinances often come with lower interest rates than personal loans. Just note that if mortgage rates are notably higher than when you opened your original home loan, refinancing may not be a smart move. You could end up paying more in total interest by the time your mortgage term ends.
One key requirement with a cash-out refinance is equity. For example, Fannie Mae generally limits a conventional cash-out refinance on a one-unit primary residence to 80% of the home’s appraised value. That means you would need to retain at least 20% equity.
You’re converting unsecured debt into debt secured by your home
An important word of warning: Consolidating your debt with a mortgage refinance means converting unsecured debt into secured debt.
When you default on unsecured debt, you can seriously damage your credit and may face collections, lawsuits, or wage garnishment. However, you may be able to negotiate or settle the debt for less than you owe—or, as a last resort, discharge eligible debt through bankruptcy. Mortgage debt, on the other hand, uses your home as collateral. If you fall far enough behind on your mortgage, the lender may eventually foreclose on your home and sell it to recover the unpaid balance.
All that to say, using your home to secure previously unsecured debt carries a significant additional risk. Think carefully before you use your home equity to consolidate unsecured balances.
When a debt consolidation refinance makes sense
Here’s a quick guide to help you decide whether a debt consolidation refinance makes sense for your situation.
Your current mortgage rate is close to today’s rates
For debt consolidation through a cash-out refinance to make sense, the math has to work in your favor. This means you aren’t accepting a mortgage rate much higher than your current rate.
For example, say your current rate is 6.5% and you qualify to refinance at 6.75%. The gap may be small enough that the lower interest rate on the consolidated debt could help justify the move. If you’ve got $25,000 in credit card debt at 22% APR, rolling that balance into a refinance at 6.75% would dramatically reduce the interest rate on that portion of your debt. Even though your new mortgage rate is slightly higher than the old one, the savings on your credit card interest alone could conceivably justify the refinance after you account for closing costs and the new repayment term.
In contrast, if you locked in a 3% rate several years ago, refinancing at 6.75% could be a huge blow. Yes, you would still replace your high-interest debt with mortgage debt, but your mortgage rate would more than double in this scenario. For comparison, a $250,000, 30-year loan at 6.75% would accrue roughly $204,000 more interest than the same loan at 3%.
The debt amount is large enough to justify closing costs
An increased interest rate isn’t the only factor to consider before you consolidate debt using your home equity. Cash-out refinances come with closing costs, too, typically between 3% and 6% of the new loan amount. On a $300,000 refinance, you’re looking at between $9,000 and $18,000 in closing costs.
Before refinancing, keep the break-even calculation in mind:
The total interest you save on the high-interest debt you’re paying off needs to exceed any additional mortgage interest resulting from the new rate, loan balance, and repayment term.
Your net savings also needs to exceed the refinance closing costs.
Because of these costs, a small debt typically isn’t a reason to initiate a cash-out refinance. For example, the interest savings on $8,000 in credit card debt may not clear the closing-cost hurdle when you’re refinancing hundreds of thousands of dollars.
You avoid running up new debt
Debt consolidation can be an effective way to save on interest—but only if you’re sure you can avoid racking up new debt. If you pay off your high-interest credit card debt through a refinance and promptly run up your balances again, you’ve only made your problem worse. Refinancing can actually leave you with the capacity to take on much more debt.
Of course, not all high-interest debt comes from impulse purchasing. You may have had emergency expenses that you needed to cover or expected income may not have arrived. But it can still be risky to consolidate your debt unless you’re confident you can avoid charging up new high-interest balances.
Other ways to consolidate debt without refinancing your mortgage
A cash-out refinance to consolidate debt may very well make no sense for your situation. Fortunately, there are several alternatives to choose from:
- Home equity loan — This second mortgage lets you borrow a lump sum against your home equity, usually at a fixed rate, without changing your existing loan. It may be better for those with a low mortgage rate and those who need a specific sum. It works similarly to a personal loan in that you’ll typically have a fixed interest rate and make equal monthly payments for the duration of your term.
- Home equity line of credit (HELOC) — Also a second mortgage, a HELOC gives you a revolving line of credit that uses your home as collateral. You can borrow, repay, and borrow again during the loan’s draw period. Rates are typically variable, but you’ll only pay interest on the portion of your credit line that you’re using, similar to a credit card.
- Balance transfer credit card — If you’ve got strong credit, a credit card with a 0% introductory APR on balance transfers can help you pay off debt more quickly. These cards often offer an interest-free period lasting 12 and 21 months, although they may charge a balance transfer fee. Any balance remaining when the introductory period ends will begin accruing interest at the card’s standard APR.
- Personal loan — You don’t need home equity to take out a personal loan. Rates are often higher than mortgage refinance rates, but an unsecured personal loan won’t put your home at risk.
How to decide if a debt consolidation refinance is right for you
Let’s distill the above down to some simple trade-offs to consider. Here’s a quick litmus test to help you decide if a debt consolidation refinance is right for you.
It likely makes sense if:
- Today’s refinance rates are at least 1 percentage point lower than your current mortgage rate.
- Your total high-interest debt is large enough that the interest savings could quickly offset the closing costs.
- You have a solid plan to avoid running up balances on the credit lines you pay off.
It likely doesn’t make sense if:
- Your new mortgage rate would be significantly higher than your current rate.
- Your high-interest debt total is small relative to your closing costs.
- The new, larger mortgage payment would strain your budget if your income dropped.
Don’t make your decision based on the monthly payment comparison alone. A monthly payment may look favorable after consolidation—but you could end up paying much more over the life of the loan. Run the total interest numbers over the full loan term before you commit.
The takeaway
If you have high-APR balances, consolidating your debt with a cash-out refinance may lower your monthly payments and interest rate.
But beware of closing costs and replacing your current mortgage with a higher-rate loan. If you don’t crunch the numbers, you may choose a refinance that lowers your monthly payment but costs you tens of thousands of dollars more in interest over the life of the loan.
Frequently asked questions
How much equity do I need for a cash-out refinance?
The exact amount varies by lender. However, you’ll generally need more than 20% equity in your home to take cash out.

What credit score do I need to refinance my mortgage for debt consolidation?
The exact credit score you need to refinance your mortgage depends on the lender, but borrowers with scores of 620 or above may be more likely to qualify.
Does consolidating credit card debt into a mortgage hurt my credit score?
Consolidating your credit card debt into a mortgage could initially hurt your credit score because of the hard credit inquiry and new account. However, paying off your credit card balances could help your score by lowering your credit utilization. The overall impact depends on your credit profile.
Will my monthly payment go down if I consolidate debt with a refinance?
Your total monthly payments may decrease after you consolidate your debt with a refinance, though your mortgage payment itself may increase.
