Keith is correct instead of going through the banks and their processes you simply go to the sheriff's department and work through a lawyer. Some simply guidelines for time have to be met and then the sheriff's department will have to remove them if they do not leave.

No, it's easier because there are fewer levels of management. Plus, the buyer gets the home back ASAP.
Eviction might be another question...and who are you? The buyer defaulting on the mortgage, or the seller?

You might want to repost.

I don't think it is any different, you just have to follow the foreclosure process.
