I want to close unnecessary accounts so I don't look scary to a potential lender for a mortgage in the next 12-24 months. No rush, but also no reason to have all of these when I only use one of them.

I ran my credit report this afternoon and I have EIGHT open CC accounts. Here is the breakdown:

I received a mortgage a few months ago and had lots of open CC accounts - way more than 8. These were left over from when I used to have a lot of CC debt. Nonetheless, my credit scores were over 800. I use Amex for most of my daily spending and I did take the precaution of paying that card throughout the month so that the billed balance was very low relative to its limit.
