<prompt> Human: I have 5 credit cards, with a total of 53,700 open to use. All have zero balances and perfect payment records. The only debt I have is a home which is not underwater and a car payment with 14,000 left to pay on an 18,000 original loan amount.Sorry if this is too much detail, I just feel it may help. My plan is to sell my current home and move to another state in the Summer of 2015. In the new state, I would purchase a home.On to my question. Should I think about closing some of my credit cards because it might impact my credit score when I go to get another mortgage. A long time ago someone told me that having too much open credit wasnt good for your score. Thoughts? If I should close some, what criteria should I use? Some are very old, some new, and the interest rates are anywhere from 0 to 24.99.There are no annual fees on any of them.  <response>: In general, closing lines of credit hurts your credit score.
