Rebuilding Credit

[Anonymous]

I have a friend who is very good when it comes to paying their bills that is ok with adding me as an authrized user on both of their AMEX cards. one has a 2k limit and the other has a 5k limit. I currently have a Credit one Bank card with a limit of 500. would it be best to keep it open or to close it or would it even make a difference being an authorized user on their account/

Thank for the input

Being an AU is kind of a mixed bag ... from what I've read, unless you share the same address and/or last name, being an AU on a friend's account won't accomplish much. 

That said, I was an AU on an ex GF's account, which thankfully she was responsible with. The account shows up on my EQ and EX, but not my TU. 

I think it's more hassle than it's worth
