So if my Fiance' adds me as an Authorized user to help build my credit (she has a $3,000 credit limit on a Capital One Card, only $300 charged currently, pays on time diligantly) -- I know this will help me.
But, if she were to add me as an AU --- would it hurt HER CR or HER rates/card?
Her interest rate was already raised automatically , along wiht everyone elses. Her IR is currently at 19.8 -- I think it is going to go up again just from reading other posts -- she has never been late on the card,and has had it for over 4 years.
Adding you as AU does not impact her credit or account, unless you were to use it in a manner that put it over the limit, etc.
AU is not financially responsible, and their CR is not a part of credit worthiness or decisions on the account.
