I know that closing credit card accounts reduces the number of open credit lines, and paying off a car loan would also reduce the number of credit lines. I have had the car loan for over 3 years, it is at 9%, but I'm not too worried about the interest cost. I want to reduce debt, but I also need to increase my credit score.
After a rough period (I had two houses and other problems), I am repairing my credit. I recently sold my old house (had the mortgage for 9 years after refinance). And I settled my second mortgage.
I have a house (and mortgage, 7 years, plan to stay for at least 2 years), I have a single credit card, and the car loan. I plan to get a (second) credit card soon.
The ideal credit mix is a mortgage, an installment loan, and 2-4 credit cards (no student loan). But it is not clear whether the car loan needs to be open for the best credit score.
These questions touch upon my question, but do not clearly answer it.
