Dear Liz: My wife and I have paid off our mortgage, we have no car loans, and we pay our credit card balances completely each month, which means that we basically pay no interest. We have four credit cards that are active and a couple more that are rarely used. My FICO score is currently just above 800. At some point we will need to replace our cars and will need car loans, so our FICO scores will be important. Since we currently have no mortgage, no car loans or any other loans, will our FICO score slowly drop, and will that affect our car loans?

Answer: Paid-off loans typically don’t disappear from your credit reports, at least not immediately. Many lenders continue to report these closed accounts for years, which contributes positively to your scores.

Even if none of these paid obligations show up on your reports, though, your responsible use of credit cards should support your high scores. Just continue to use your cards lightly but regularly and pay off all balances in full.

Since you have time before you plan to replace your cars, consider paying cash for them, or at least making a substantial down payment. It’s typically best to use loans only for assets that appreciate — and cars certainly don’t do that.
