Your home was not sold to fnma, chase was the servicer of the loan and fnma was the investor. A bankrutpcy would do little but stall the process. IF you have documentation inidcating a workout was approved then you might be able to get your property back, but if no paper trail it is unlikley FNMA will entertain a workout. In NJ the foreclosure time frame is long and fnma will think you had a long enough time to reslove the issue.
