Yes, homeowners with enough equity can consolidate credit card debt into a mortgage, using one of three tools: a cash-out refinance, a home equity loan, or a home equity line of credit. All three convert unsecured card balances into debt secured by your home, which is how you get a much lower interest rate and also how you put the house at risk. Whether it’s the right move depends on how much equity you have, how your income supports a larger housing payment, and whether you’ll change the habits that created the card balances.
The Three Ways to Do It
A cash-out refinance replaces your existing mortgage with a new, larger one. The lender pays off your old loan, then hands you the difference in cash to pay down the cards. You end up with a single monthly payment at a new rate applied to the full balance, but you also restart the loan term. If you’ve been paying down your mortgage for years, the clock resets.
A home equity loan gives you a lump sum at a fixed interest rate, repaid on a set schedule that commonly runs five to twenty years. Your original mortgage stays in place; the new loan sits behind it as a second lien, and the lender records a deed of trust against the property. You’ll carry two mortgage payments, but the fixed rate makes the second one predictable.
A HELOC works like a revolving account secured by your home. You draw against a credit limit as needed and pay interest on what you’ve used. Most HELOCs carry a variable rate tied to the Wall Street Journal Prime Rate, so the payment moves when rates move. Like a home equity loan, it sits behind your first mortgage as a second lien.
Do You Qualify?
Equity: The 80% Rule
The first gatekeeper is equity. For a conventional cash-out refinance, Fannie Mae and Freddie Mac both cap the loan-to-value ratio at 80% on a single-unit primary residence, meaning you must keep at least 20% equity in the home after closing.1Fannie Mae. Eligibility Matrix2Freddie Mac. Maximum LTV/TLTV/HTLTV Ratio Requirements for Conforming and Super Conforming Mortgages On a home that appraises at $400,000, your total loan balance after consolidation can’t exceed $320,000. Anything past that gets rejected under standard conventional guidelines.
Debt-to-Income Ratio
Lenders measure total monthly debt payments, including the new larger mortgage, against your gross monthly income. Fannie Mae allows a maximum debt-to-income ratio of 50% on loans run through its automated underwriting system. Manually underwritten loans face a tighter 36% ceiling, with allowances up to 45% for borrowers who meet higher credit score and reserve requirements.3Fannie Mae. Debt-to-Income Ratios The calculation folds in the proposed mortgage payment, property taxes, homeowner’s insurance, and every recurring debt.
Credit Score
Most conventional programs require a minimum score of 620, and a higher score gets you a better rate. Underwriters also look past the number: recent late payments, maxed-out cards, and short histories all draw scrutiny. If you’re consolidating because your cards are near their limits, that high utilization ratio may already be dragging your score down. Check where you stand before applying.
Seasoning
You can’t buy a home and immediately cash out. Fannie Mae requires that your existing first mortgage be at least 12 months old, measured from note date to note date, and at least one borrower must have been on the property title for a minimum of six months before the new loan funds.4Fannie Mae.

Cash Reserves
Fannie Mae doesn’t set a minimum reserve requirement in most one-unit primary residence cash-out cases, but if your debt-to-income ratio exceeds 45%, you’ll need six months of liquid reserves after closing, enough cash on hand to cover six full mortgage payments.5Fannie Mae. 6Veterans Affairs.

VA Funding Fee And Loan Closing Costs The fee can be rolled into the loan, but that adds to the balance you’re carrying.
What It Costs Upfront
Consolidating isn’t free, and the closing costs can erode or wipe out the savings from a lower interest rate. A cash-out refinance typically runs 2% to 6% of the new loan balance. On a $300,000 refinance, that’s $6,000 to $18,000 covering the appraisal, title search, title insurance, origination, and recording fees. Home equity loans and HELOCs generally run 2% to 5% of the amount or credit limit. Some lenders advertise no-closing-cost home equity products, but they recover the money through a higher interest rate.
A professional appraisal is required for nearly every consolidation transaction, and inspection fees for a standard single-family home commonly run $525 to $800 depending on the market. Government recording fees vary by jurisdiction. Ask the lender for a Loan Estimate and calculate your break-even point. If it takes five or six years for the interest savings to recover the closing costs, and you might sell before then, the math doesn’t work.
The Tax Trap
Here’s where borrowers often get bad advice. Interest on a home equity loan, HELOC, or cash-out refinance is deductible only if the borrowed funds are used to buy, build, or substantially improve the home securing the loan. When the money pays off credit cards, that portion of the interest is not deductible.8Internal Revenue Service. Publication 936 – Home Mortgage Interest Deduction
The One Big Beautiful Bill Act, signed in 2025, made the $750,000 cap on deductible mortgage debt permanent ($375,000 for married filing separately). For consolidation, though, the cap is beside the point: even if your total mortgage debt sits well under $750,000, interest attributable to a card payoff still doesn’t qualify.8Internal Revenue Service. Publication 936 – Home Mortgage Interest Deduction If a lender or advisor pitches a tax benefit as part of the deal, push back. The savings come from the lower rate alone.
The Risks That Should Drive Your Decision
Your House Becomes the Collateral
Credit card debt is unsecured. If you default on a card, the issuer can send you to collections, sue you, and damage your credit, but the card company cannot take your home. The moment you fold that debt into a mortgage, foreclosure becomes the consequence for missed payments. This is the single most important consideration, and it’s the one rate-comparison calculators tend to bury.
Decades of Interest on Old Balances
Spreading $30,000 in card debt over a 30-year mortgage dramatically cuts the monthly payment, but you’ll pay interest on that balance for decades. Run the total interest over the life of the loan, not just the monthly savings. A lower rate stretched over 30 years can cost more in absolute dollars than a higher rate paid off aggressively in three or four.
The Repeat-Spending Problem
After consolidation, your cards show zero balances and full available credit. The temptation to run them back up is real. Consolidate $25,000 in card debt into your mortgage, charge another $25,000 over the next two years, and you’ve doubled your total debt while also putting your home on the line. This strategy only works if the spending pattern that created the debt actually changes.
Mixed Effects on Your Credit
Paying off card balances drops your credit utilization ratio, which helps your score. Closing those accounts afterward reduces your total available credit and shortens the average account age, both of which hurt. Leaving the cards open at zero is better for the score but leaves the temptation in place. There’s no clean answer, only a trade-off you make deliberately.
