<prompt> Human: Title is pretty self explanatory... I had about 19k in credit card debt and its almost to zero. Id moved to San Francisco and didnt have a job, and now I have a well paying job and now my debt it gone. I read somewhere that closing credit cards can hurt your credit. Is that true? I think I have something like 20k - 30k in available credit.Thanks guys!  <response>: If there are no annual fees on the cards, keep them open. Having a low utilizationhaving a long history of credit are both good for your credit score. Just make sure to use them occasionally or they might close them due to inactivity. For the cards Ive had for 10 years but no longer regularly use, I set up automatic subscription fees to keep the cards active Netflix, Hulu, Amazon and then pay the cards off every month.
