Hi All. I've been reading these forums for a couple weeks and thought I would join in.
I'm 22, I just graduated from college (in June) and got a relatively high paying job shortly thereafter. Recently I began thinking now would be as good of time as any to begin building my credit scores. In reading through these forums, I've seen many people suggest going on an application "spree", so I applied for 3 cards on the same day.
Through various phone calls over the following days I ended up getting approved for all 3. The cards were a B of A cash rewards signature visa ($5k limit), discover miles ($3k limit), and amex zync. To be honest I was surprised I was approved for any of them, let alone all 3 because I had previously never had my own credit card nor been attached to my parents accounts in any way.
A couple days ago I pulled my credit scores and they were all between 720 and 750 (pulled from myFico (EX from Amex application)). Ideally I would like to stick with AMEX and work my way up through their cards. I will be able to pay all 3 cards in full every month. I am aware that I should stay with these current cards for some time to build a credit history before looking to upgrade.
My question is, how long would you recommend I stay with these current cards before I look to add an Amex Green/Amex Gold/Amex Premier Rewards Gold/Amex Platinum to my wallet?
(P.S. I have roughly $18k in student loans for which payments begin Jan 2012)
