I got some advice for you. Be patient with the rewards, they are harder to get, and if you do get it, they will jack up the interest rates beyond anything.
This is my story:
Turned 18, got the citibank platinum select for
college students. 16% no fee 6 months intro of 0% 1,200 credit line
2 months later, by suggestion of my father(who is a loan officer, knows all about building your credit score) I picked up another card, this time from capital one.
Just your average credit card, 20% no fee 200 credit line.
Avoid late payments.
Paying off you balance in full each month will save you a bundle. Doesnt really affect your credit score to much tho.
Keep 2-4 Cards open.
Do not close too many accounts, try to keep them open for at least 2 years before you cancel/close a credit card.
And now here I am, a little less than 2 years later;
I recently recieved the citibank platinum select dividends card. %1 back on everything %5 back on gas/groceries 11% interest rate, no fee, 2400 credit line
A week after I got the capital one Go Cash. 1% back on everything. 10% interest rate, no fee, 5000 credit line.
So Now Im just chilling, building my credit and getting cash back on stuff i would normally buy anyways!
Hope this post helped!
