Oh, I'm sure I have a credit score
I now use credit cards for points/rewards/rebate don't carry a balance on any of my major credit cards. And while I no longer have a car note or student loan, but I will be paying on my mortgages for at least the next 15-20 years.
I'd like to make ensure my credits the best it can be so that I can try to refinance mortgage debt into a lower rate an shorter term loan.
I am speaking of the few store cards I've gotten for large purchases at promotional rates (for instance, whole house carpet at 0% interest and paid off in full before the promo period ended, for instance) that I don't see myself using in the foreseeable future. I know they count as open credit lines.
