I suggest you contact a lender with regard to your credit and ask them to pull a credit report. Sometimes credit is better or worse than originally thought, but if you don't know where you are - you can't possibly know "where" or how far you need to go. Perhaps you simply need to rebuild your credit or pay off a few outstanding debts unresolved in your bankruptcy. A lender can give you a strategy and an approximate timeline for home ownership. They can also give you a prediction of estimated costs (down payment and closing) associated with various types of mortgages. This is the info you need, and you can only get it from a lender.
Best of luck to you!
