A cash-out refinance to pay off debt can make sense when the new mortgage payment is meaningfully lower than your current mortgage plus the payments it retires, you plan to stay in the home, and the spending that built the balances is under control. It is a poor trade when it swaps a low first mortgage rate for a higher one, or when the cards are likely to fill back up.
What actually changes
Two things happen when you roll debt into your mortgage, and both deserve a clear look.
Unsecured debt becomes secured debt. A credit card company cannot take your house. A mortgage lender can. You are trading a debt with ugly terms and limited consequences for one with better terms and serious consequences.
Short debt becomes long debt. A car loan ends in a few years. A card can be paid off in a few years with discipline. Put those balances into a 30-year mortgage and you may pay less each month while paying for that dinner, that vacation and that transmission until the 2050s.
Neither point means do not do it. They mean the monthly payment is not the only number to check.
The four numbers to compare
Ask your loan officer for these side by side, in writing.
- Total monthly outlay, before and after. Add your current mortgage payment to every debt payment you would retire. Compare it with the new mortgage payment, including taxes, insurance and any mortgage insurance.
- Total interest, before and after. What you would pay on the current path against what you would pay on the new loan over the time you expect to keep it.
- Cost to do it and the break-even. Closing costs divided by the monthly savings tells you how many months it takes to come out ahead. See When Should I Refinance?.
- Equity left afterward. Most programs leave about 20% in the home. See How Much Equity Do I Need for a Cash-Out Refinance?.
The rate trap
A cash-out refinance replaces your whole first mortgage, not just the part you are borrowing. If you locked in a low rate years ago, repricing the entire balance to pay off a smaller amount of card debt can cost more than it saves.
A simple way to see it is the blended rate: weigh each debt by its balance and compare the average against the new mortgage rate. A large mortgage at a low rate plus a small card balance at a high rate often blends to a lower number than people expect.
When the first mortgage is worth protecting, a second lien is usually the better tool. A home equity loan or line of credit sits behind the first mortgage and leaves it alone. See Cash-Out Refinance vs HELOC.
How it affects qualifying
- Debt-to-income. Debts paid off at closing usually drop out of the ratio. That can turn a file that does not fit into one that does. See Debt-to-Income Ratio Explained.
- Payoffs at closing. When the approval depends on those payoffs, the title company pays the creditors directly from the proceeds. You do not receive that money and pay them yourself.
- Closing accounts. Some approvals require certain accounts to be closed as well as paid.
- Credit scores. Lower card balances often help a score over time. Closed accounts and a new mortgage inquiry can pull the other way for a while. Nobody can promise a number.
When it tends to work
- The total monthly outlay falls by an amount that changes your life, not a rounding error.
- Your current first mortgage rate is at or above today's market, so you lose little by replacing it.
- You expect to stay in the home well past the break-even point.
- The debt came from a one-time event such as medical bills, a divorce, a business slow year or a major repair.
- You plan to keep paying something close to the old total, so the loan shrinks faster than scheduled.
When it tends not to
- Your first mortgage rate is far below today's market.
- You may sell or move within a couple of years.
- The balances came from routine overspending that has not changed.
- You would be left with too little equity to sell without bringing money to closing.
- The debt is small enough to clear in two or three years with a tight budget.
Other ways to solve the same problem
- Home equity loan or line of credit. Protects the first mortgage.
- A structured payoff. Highest rate first, fixed monthly amount, no new charges.
- Nonprofit credit counseling. A debt management plan through an agency affiliated with the National Foundation for Credit Counseling can lower card rates without a new loan.
- A personal loan. Unsecured, shorter term, and nothing recorded against the house.
A good loan officer should be willing to tell you when one of these beats the refinance.
Protect the fix
A consolidation that is followed by new balances leaves you worse off than before: the cards are full again and the house now carries the old debt.
- Keep one card for convenience with automatic payment in full. Put the rest away.
- Send part of the monthly savings to principal and part to an emergency fund.
- Review the plan every six months with someone who will be honest with you.
A note on taxes
Under current IRS guidance in Publication 936, mortgage interest is generally deductible only on debt used to buy, build or substantially improve the home. Interest on the portion used to pay off cards or cars usually does not qualify. Ask a tax professional how that applies to you.
