but weren't the monthly statements being sent to your house?
this would have taken a year or more to foment.
If you already have a notice of the Trustee Sale, you will only have about 5-6 weeks after the Sale.
The good news is, you should be offer Moving Money; unless he intercepts that like he intercepted the monthly statements.
You could also try to do a short sale and you might be able to not only stay at your house while this process is being done, but you could also be able to get some money for relocation assistance.
The most important is that you would need to hire somebody with experience in this field to assist you.
I would be happy to help you!
