Okay, so I recently have applied for the Citi AA card, Chase CO, and Cap1 Venture. I have an old Sears Citi card and it had a link to get my credit score for free so I signed up. I think it is the same as credit karma, it pulls information from my TransUnion info only. So, I'm trying to put together all of this information. It looks like I'm doing okay overall, but I'm trying to put together a few things. Apparently I have 36 total accounts showing up???? I have no idea what all of these accounts are. It says 12 are closed accounts. How long do closed accounts continue to show up? Also, I know I've been an authorized user on some of my mom and husband's accounts, will that show up on my report? Also, the average age of my open credit lines is 7 years with my longest being almost 15 years. I will keep that longest card open for sure, but I had a couple of cards floating out there, like the Sears Citi, that I was going to close to not have so many accounts, but will that hurt me then? Which is worse, having so many open accounts or closing some slightly old accounts? Thanks for any thoughts, I am so new to this, I never got several credit cards at once like this so never really thought about credit. I already have my mortgage, so that's not a problem.
