For the financial experts out there, Capital One is going to close my credit card due to inactivity. I called them and they said there is no possible way they could reopen it because its been flagged for closure, even after being sent up the chain. The problem is it's my oldest account, going over 10 years. It was a relatively small amount of credit, so I'm not worried about that, but my main card, USAA is only a few years old. I've always had an excellent credit rating, no missed payments, and a few loans paid off, but I think a good portion of that was due my long credit history. The reason this is a problem is I'm planning on buying a house this summer as soon as my current lease expires. How will this affect my credit rating?
