No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
Just pay in full when the statement arrives. Why pay huge interest fees to keep a balance running? You will lose a lot of money this way. Keep utilization under 10% if you're trying to get a loan soon. If you need to go over 10%, just use a debit card or cash so it won't affect your credit utilization.
Over the next few months my utilization will be higher than normal. But I've decided not to worry too much about it. I have long interest free periods on multiple cards now (Discover, Quicksilver, etc) so I'm good with it. I am not applying for new credit for at least a year so I'll just be paying balances and enjoying life. I will still pay more than the minimums but that is because I am in a position to do so. Given the choice, I will always do that as I just feel better with low balances.
