That is likely because you were using to much of the available credit that is not good for your credit report either, you would have been better off paying off the cards and keeping them unless the temptation to use them is to great for you.I disagree, when I bought my 3rd house (while owning 2 others) I had to pay off and cancel a couple of credit cards first to get financing. The more open lines of credit the more risk. Last time I purchased a new vehicle my FICA score was 844, and that was after cancelling some credit cards, so I'm not sure how cancelling a credit card will hurt you. Now opening several new ones can lower your score, but closing old ones is unlikely.
