You can roll credit card debt into a mortgage through one of three products: a cash-out refinance, a home equity loan, or a home equity line of credit. Each replaces unsecured card balances charging around 21% with debt secured by your house at roughly 6% to 7%. The rate gap is real, but so is the tradeoff. You are converting debt that can only bruise your credit into debt that can cost you the house, and stretching a five-year balance across 30 years can leave you paying more total interest than the cards would have charged. Whether this move helps depends on your equity, your discipline about extra payments, and whether the spending that created the debt has actually stopped.
The Three Ways to Do It
Cash-Out Refinance
A cash-out refinance replaces your existing mortgage with a new, larger one. The old loan is paid off and you pocket the difference as cash to wipe out card balances. You end up with a single monthly payment, a new interest rate, and a fresh 15- or 30-year clock. It is the cleanest option if the new rate is competitive, but it resets your payoff timeline.
Home Equity Loan
A home equity loan is a second mortgage. You get a lump sum at a fixed rate while your original mortgage stays in place.1Federal Trade Commission. Home Equity Loans and Home Equity Lines of Credit You then make two monthly payments. The advantage is that you do not disturb a low rate you may already have on the first mortgage. The disadvantage is managing two loans instead of one.
Home Equity Line of Credit
A HELOC is a revolving credit line secured by your home rather than a one-time payout.2Consumer Financial Protection Bureau. What You Should Know About Home Equity Lines of Credit During the draw period you take what you need and pay interest only on what you have used. Rates are typically variable, so your payment can climb if rates rise. This works for borrowers who want to pay off cards in stages.
Whether You Qualify
Credit Score
Fannie Mae and Freddie Mac both set a 620 minimum score for a conventional cash-out refinance.3Fannie Mae. Eligibility Matrix4Freddie Mac. Cash-Out Refinance FHA cash-out refinances allow scores as low as 580, but FHA loans require an upfront mortgage insurance premium of 1.75% of the loan amount plus an annual premium (typically 0.55%) added to your monthly payment. Those extras can swallow much of the interest savings you were chasing.
Equity in the Home
The loan-to-value ratio is the biggest gate. On a conventional cash-out refinance, the new mortgage balance cannot exceed 80% of your home’s appraised value.3Fannie Mae. Eligibility Matrix You need at least 20% equity left after the new loan funds. If your home appraises at $400,000 and you owe $280,000, the maximum new loan is $320,000, leaving $40,000 to cover both credit card payoff and closing costs.
Debt-to-Income Ratio
Federal ability-to-repay rules require the lender to verify you can actually handle the new payment.5Consumer Financial Protection Bureau. Ability-to-Repay and Qualified Mortgage Rule Small Entity Compliance Guide The traditional DTI cap is 43%, though Fannie Mae’s automated underwriting can approve up to 50% when strong credit or cash reserves offset the higher ratio.6Fannie Mae. Updates to the Debt-to-Income Ratio Assessment The number being tested is your new, larger mortgage payment, not the old one.
How Long You’ve Owned
You cannot buy a home and cash out the next week. Fannie Mae requires at least one borrower to have been on title for six months before the new loan disburses, and the mortgage being refinanced must be at least 12 months old.7Fannie Mae. Cash-Out Refinance Transactions There are narrow exceptions for inherited property and property received in a divorce.
VA Borrowers Get Better Terms
Veterans and eligible service members have an option nobody else does. A VA-backed cash-out refinance explicitly permits pulling equity to pay off debt, and the maximum LTV runs up to 100% of the appraised value.8Veterans Affairs. Cash-Out Refinance Loan You’ll need a Certificate of Eligibility and must occupy the home. The equity cushion that blocks many conventional applicants does not apply.
What This Actually Costs
The rate drop looks dramatic in isolation. Rate alone is not what determines what you pay.
Total Interest Over 30 Years
Roll $30,000 in card debt into a 30-year mortgage at 6.5% and you will pay roughly $38,000 in interest on that piece over the life of the loan. Attack the same $30,000 on the cards at 21% with $600 monthly payments and you clear it in about six years for around $13,000 in interest. The mortgage rate is one-third the card rate, yet total interest is nearly triple, because the repayment window is six times longer. The only way to capture real savings is to keep making extra principal payments on the mortgage as if the card debt were still on the cards. Most people don’t.
Closing Costs
A cash-out refinance carries closing costs of 3% to 6% of the new loan amount.9Freddie Mac. Understanding the Costs of Refinancing On a $320,000 refinance, that’s $9,600 to $19,200 in appraisal, title, origination, and recording fees. These costs are typically rolled into the new balance, which means you borrow to pay them and then pay interest on them for decades. If you are consolidating $20,000 in card debt and spending $12,000 to do it, the math turns against you fast.
You Cannot Deduct the Interest
A common assumption is that mortgage interest becomes deductible once card debt is folded in. It does not. Under IRS rules, mortgage interest is deductible only when the loan proceeds are used to buy, build, or substantially improve the home securing the loan.10Internal Revenue Service. Publication 936, Home Mortgage Interest Deduction Money used to pay off credit cards fails that test. The portion of your new mortgage that went to card payoff is personal interest and stays nondeductible. Anyone building a tax benefit into their consolidation math is working with the wrong numbers.
Your House Now Backs the Debt
Credit card debt is unsecured. If you stop paying, the issuer can sue you, wreck your credit, and eventually garnish wages, but nobody takes your home. Once you fold that debt into a mortgage, the lender holds a lien on your property. Fall behind and foreclosure becomes a real possibility. This is the piece people gloss over most often. If unstable finances created the card balances in the first place, tying that same debt to your home amplifies the risk rather than resolving it.
One More Protection to Know About
Federal law gives you three business days to cancel most refinance transactions on your primary home after signing, receiving your closing disclosures, and receiving notice of your rescission rights.11Consumer Financial Protection Bureau. Comment for 1026.23 – Right of Rescission The lender cannot disburse funds until that window closes.12Consumer Financial Protection Bureau. How Long Do I Have to Rescind? On a cash-out refinance with the same lender, the rescission right applies only to the new cash-out portion above your existing balance.13eCFR. 12 CFR 1026.23 – Right of Rescission After that period, the mortgage company usually pays the card issuers directly using the account information from your application, which is safer than receiving a lump sum and being trusted to send it along.
When It Actually Makes Sense
The circumstances where this works are narrower than the pitch suggests. You need substantial equity, a real rate drop, the discipline to make extra principal payments, and enough income stability that missing the mortgage is not a plausible scenario. Consolidate $30,000 and commit to paying that same amount down within five years through additional principal, and the interest savings can be genuine. Stretch it across 30 years at a modestly lower rate, pay thousands in closing costs, and lose no tax benefit because there was none to lose, and you have made an expensive lateral move that also puts your home at risk.
The borrowers who get burned tend to consolidate, feel the relief of a lower monthly payment, and slowly run the cards back up. Now they carry the bigger mortgage and fresh card balances, worse off than before. Run the full math before choosing this path: compare total interest over the timeline you will actually commit to, add closing costs, and be honest about whether the habits that produced the debt have changed.
