Given the fact you claim your score is not the best, I definitely think this was not the best decision. Paying off the credit cards is a great idea. Closing them, is not, because not only do you have to worry about high utilization on the card you currently have open, but, you have also lost your history, which will often cause the score to drop significantly. It's like not having any credit at all (besides the currently open loans), and starting over. I recommend you not use any more than about $100 monthly on your $500 credit card, and focus on making timely payments on your other loans. Although different folks have different philosophies on whether to have credit cards, not, I still think it is very smart to at least HAVE the credit cards just in case there is a rainy day (especially if you do not have much disposable cash). The beauty of having credit cards is that, they're there when you need them, they help build a strong score and history that can even get you discounts and save you plenty money with certain items, and alas, if you don't want to use it...well, you don't have to.
