It is not fraud to surrender a mobile home back to a lender after a bankruptcy. If you didn't reaffirm on the mobile home loan in the bankruptcy, the lender cannot legally pursue you for a deficiency on the loan. However, the credit bureau can still report the repossession on your credit report. You really should speak with your bankruptcy attorney about this before you do anything. Good Luck!
Don't let anyone tell you that reaffirmation will help you build your credit score, that just is not true. If you want your credit report to show that you have faithfully paid, then write a dispute letter to each credit reporting agency and attach a copy of the payment history to show that you have paid.
If you did not reaffirm, and want to surrender the mobile home, you can do that, and then your credit report should show the loan was discharged in bankruptcy.

I am not your attorney unless you and I have signed a retainer agreement. What I am saying is not legal advice. Do not act on this information without engaging my services, this is for consideration only.
So long as you did not reaffirm the old mobile home loan, you can surrender it back and not be responsible for the difference when they resell it. If it shows up on your credit report as still due, you can send a copy of your schedules and the discharge to the credit reporting agency and dispute it.
