Since the filing of your bankruptcy what have you done as far as reestablishing your credit? In other words did you keep one credit card account opened that you reaffirmed? If not have you gotten new credit and if you did have you made all payments on time?
I have been through bankruptcy and I will tell you this. No creditor is going to hand you out new credit even though the bankruptcy has wiped out your debts. You may need to start of with secured accounts were cash in a savings account is used as collateral. To a new lender you are a very high risk. This is never a guarantee that you will get credit but it would be a good idea to add a consumer statement with each credit bureau to why you filed bankruptcy. On my statement it says "bankruptcy filed do to serious medical accident". The other thing is to be up front and completely honest with the lender.
After a bankruptcy your credit rating and fico score are not going to go up over night. You have to work at it by making all payments on time. Do not be late with any creditor or any account even once for any reason. With a bankruptcy filing I have found that creditors would like to see three open accounts so that they can get a better feel of your credit character.
I have been working on my credit since April of 2003 when I filed my medical bankruptcy. Here I am 5 years later and my score could possible be between 720-772, according to the fico score simulator. Did you try the fico score simulator to see were you stand? If not I would highly recommend it.
