Closing unused credit cards can tank your score because zero-balance cards keep reporting positive info to bureaus. Instead, keep them open or downgrade to a no-fee version to preserve your credit line.
Banks don't want you to know this, but it's better to keep unused credit cards open rather than canceling them. See, unused credit cards with a zero balance will still report positive information to the credit bureaus every month, which will only help increase your score. If your card has annual fees that you need to pay, then you can just downgrade to a fee free option. That way your credit line still stays open. Share this with someone who uses a credit card.
