Wrong!
pay it off except the last 10 bucks. Keep a very small balance. Paying cards off, still hurt your credit rating.
Also, go to your CU/bank and get several (like literally 10) signature/collateral loans (secured). So you take 1k in and ask for a loan of 1k using your
1k as collateral. Then, take the 1k they loan you and do it over and over. make your minimum payments every month and carry these loans out in
varying lengths - no smaller than 12 months though.
DO NOT pay them off sooner than that, however, if you take some that are over 5 years (yes, 1k), you can pay 4 years up front and re-ammoritize them over the 60 months left.
Welcome to having a 800 credit score right out of HS. Well, in 2 years. Oh, and have at LEAST 2 revolving lines (CCs). Small limits are ok, but 2k is better. No more than 5k if you only make 30k/yr less.
