<prompt> Human: I have a large purchase Im planning 3,500 and the company offers a finance option through opening a GE credit card with no interest for 1 year. I have good credit last score was 777, no late payments or anything negative on my account. Im not planning on buying a house or car in at least a few years. Currently have 3 open credit cards. Ive heard that opening then closing a credit card affects your credit, but does it just affect your debt to credit ratio or is it looked on as a negative thing to open and close another card?  <response>: Closing a line of credit will lower your access to credit, which can be negative. If you have an open line of credit, but you arent using it AND there is no annualinactivityother hidden fee associated with leaving it alone, then not closing it will be beneficial to your score.It would affect your total credit utilization ratio by reducing your access to credit.For more information about credit reports and scores, check out:Hope that helped.-RethinkingDebt.org
