Having been on the receiving end of a foreclosure (our landlord stopped paying the damn bill while we were renting), I can tell you these contractors they hire are ruthless. We had people showing up at all hours trying to look in to the house, worm their way inside (it wasn't even the bank's house yet), etc.
