<prompt> Human: Apologies if this is an old or stupid question, but Ive carefully read the FICO FAQ, looked up the word tradeline, and used the search box.Ive been wanting to get out of Chase for a long time, but its my oldest account by eight years. My oldest credit card account was opened in 2007; My Chase checkingsavings account was opened as WashMutual in 1999.It seems from the FAQ that oldest tradeline affects your credit score and a tradeline is just a line of credit. So the only oldest account that matters is my oldest credit account, right?I want to make sure before I do something potentially stupid.  <response>: You are correct. Closing checkingsaving accounts do not affect your credit. Closing your oldest credit card would affect your credit.
