We went through forclosure a few years ago, we also lost a motorhome and a minivan all at the same time. There wasn't much to it really. We moved out before they came in. Generally you'll have 30-90 days before anything really happens. They have to go through court proceedings and issue an eviction type notice that has to be served. Etc etc.
The one good thing that actually came out of it all was that the following spring when we filed our taxes, we ended up getting a refund of $12,000.00 because of the losses we incurred. If you get yourself a good accountant you may be able to benefit from this hardship as well. Noone wants to lose their home, but sometimes things just happen. I think I paid my accountant $150.00 for his service and he is on the up and up, he just happens to know what he is doing!
I wish you the best of luck in a heartbreaking and difficult situation.
