BpoBill, You are obviously not in California where law mostly protects the occupant! If the occupants file bankruptcy, that buys them at least another 6 months, and you REALLY wouldn't want to be the one who changed the locks!
That is usually why the banks use an eviction service in this State.
If the occupants file bk, the evictions department would tell me. Then I wouldnt rekey. You act like im beating the door down on an orphanage and kicking them out lol. Dont worry about how I run my business. I do things effectively and legally.
