here are some good student cards LINK
You need 3 lines of credit to buy a house?
Is one credit card one line?
Would I have to get 2 other credit cards (in due time)?
I dont think you need 3 lines of credit i think you need 3 credit scores.. so it basically all depends on who your card reports to.
I have 1 credit card... have had it since school. went to apply for a loan here recently and they denied me because i have "thin" credit. essentially my CC was only reporting to 2 of the bureaus...
so the lesson to be learned (you are way ahead of me) is to not sign up for a ton of credit cards but do seek out ways to improve your score...
can you piggy back your parents. ie get added as an authorized user... they don't have to give u a card just add u on their account.
