I honestly don't know what my credit score did, because I had never pulled my score before filing. I took out an unsecured Orchard Bank CC right after filing, and although it has a $59 annual fee, it has been a good step in re-establishing. I also got a line of credit at my credit union. Then, in December I got a NORMAL credit card from my credit union with no annual fee with a $1000 limit. Finally, in March, I took out an auto loan. My scores currently range from 656-680 depending on who I've talked to.
I actually found that the score I received on this website was 10+ points higher than the score at the credit union when I got my car loan (both through the same credit reporting agency, though). This caused a higher interest rate which I was disappointed in.
Anyway, I"ve heard that BK can ruin you, but I honestly haven't felt that way. BUT, I have been VERY responsible since BK.......NO lates, and slowly increasing my credit.
Good luck!
