Balance transfer card. A card company moves your balances onto one card, often at a promotional price. The CFPB notes that the promotion lasts a limited time, that you will probably pay a balance transfer fee, and that new purchases on the same card get no grace period1.
Debt consolidation loan. A bank, credit union or installment lender pays off several debts with one loan. The CFPB warns that low advertised pricing may be a teaser that rises later, and that a lower monthly payment can simply mean a longer loan that costs more overall, including fees1.
Home equity loan. Borrowing against your home turns unsecured card debt into debt secured by the house. The CFPB calls this risky: if you cannot repay, you could lose the home to foreclosure, and closing costs can run to hundreds or thousands of dollars1.
Before any of these. The CFPB suggests a free session with a nonprofit credit counselor, a budget, and asking each creditor whether it will lower payments or waive fees1.
