Dear Liz: I will be inheriting around $300,000 over the next year. My instincts are to pay down debt with this money. I have two homes and for practical reasons need to keep them. One home has a $260,000 mortgage balance at 5%. The other has a $130,000 mortgage at 4%. We have $35,000 in credit card balances. Some are telling us to invest. I think we should pay off all the credit cards and then pay down the larger mortgage by $100,000 or more. Am I on the right track?

Answer: Paying off your whopping credit card debt is a great idea. You need to figure out, though, what caused you to rack up so much debt and fix that problem. Otherwise, you’re likely to find yourself back in the hole.

Paying down a mortgage is a trickier proposition. Most people have better things to do with their money than prepay a low-rate, tax-deductible debt. Before they consider doing so, they should make sure they’re saving adequately for retirement, that all their other debt is paid off, that they have a substantial emergency fund of at least six months’ worth of expenses, and that they’re adequately insured with appropriate health, property, life and disability coverage. Those with children should think about funding a college savings plan.

If you’ve covered all these bases, then paying down and perhaps refinancing the larger mortgage makes sense.
