Capital One approved me for a $300 unsecured when I had an active charge-off with them from another Capital One unsecured, so it seems that is for sure a good starting point. If you can find yourself a nice offer from First Premier with a low AF and NO monthly then they will approve you too. My score was ~500 and they approved me for $800 unsecured, but be VERY careful with them and ONLY use the card to get a positive TL, do NOT carry a balance and if you lose your job or something pay the card to $0 and just leave it alone.
Starting Score: 532/564 10/21/12
