My mum went through a similar situation back in the late 90's to early 2003. When mum signed on the dotted line to accept the loan, a woman that was helping her to arrange such unexpected housing, made her believe that this was the best way to get out of her then current situation. I was fortunate that mum and I had housing, however, I had a very odd feeling that the mortgage company was not going to be all roses and butterflies.
Sure enough, not even a season later, mum discovered the series of harassing phone calls from Green Tree that awaited her. They called all hours of the day and night. Sometimes the callers made it sound like they were going to throw fire on the mobile home just to blame it on either mum and me. Green Tree reps were also causing mum a lot of emotional and physical health problems due to the harassment. Of course, Green Tree reps blamed her for her own health status and of course, belittled me for living with her, and felt that I was old enough to live on my own. Mum had severe cardiac trouble and the school I attended for my A.A. degree was only a few miles away, I wasn't going to live somewhere else when her health was at that status.
Long story short, I had six and half years worth of hell lifted from my shoulders as well as mum's when we essentially abandoned the home, moved into a very nice apartment and mailed the keys to the nearest Green Tree office. Never heard from them again, with the exception a marking on mum's credit report.
