When you discharge your debts everyone always refers to the experience as starting over. In a lot of ways it really is, and when it comes to your future financial history goals that's really how you should look at it. You've already worked on cleaning up your history the best you can, now it's time to work on reestablishing credit after bankruptcy.
When you were younger and first starting out you had to establish yourself financially. Before you did that you were seen as an unknown, which many consider to be worse than someone with a negative history. This is because they just aren't sure what you'll do. Well, with your recent past some individuals will want to trust that you're looking to start over, but few will be willing to work with you until you've done something more substantial to show that to them.
For this reason you need to look at how to work on reestablishing credit after bankruptcy. Your financial history is made up of two types of payments: installment (loans) and revolving (cards). You need positive history in both areas to have a good rating.
It's usually easiest to start looking at secured cards. You deposit upwards of a few hundred dollars in a savings account, which the company will hold and use as collateral (and the limit) on your card. You want to pay this off in full each month and use it lightly (less than 30% of the limit) to build up a good history use.
Eventually you want to look into small (preferably secured) loans to build up a history in this area.
If you keep on top of things, you can have a fairly good score in as little as two years. Reestablishing credit after bankruptcy requires persistence, but your efforts will be worth it to finally have an easier time with your finances.
