Now that our sense of entitlement and excess is being threatened people have a problem?

Since her mom was involved to such an extent, something tells me that tenant B is used to getting her way, and gets pretty bent out of shape when things don't go exactly as she wants.Also, there appears to be more (albeit, anecdotal) evidence that these weed-heads were reasonable in the face of gentle confrontation and didn't threaten you and your entire extended family with violence and revenge.  

They turned into a landlord's nightmare - calling the town inspector for extremely minor issues, without ever having informed us of any problems, denying us access to the unit to make these extremely minor repairs, parking in such a way as to block access to the lot, sending us foul languaged and threatening texts.  

All he can do is say no and all you can do is then threaten to pull the loan from him.

Sad that you find such an odd thing threatening. 

They threatened me with a lawsuit claiming constructive eviction.

The daughter threatened me physically as well as swearing at me.

Before I arrived, I asked the PM to ensure the tenant had relinquished possession of the home so I would actually have the right to enter.Why wouldn't I be angry and feel like my asset had been threatened when I heard the PM actually DIDN'T go put a lockbox on the door, and instead, the house key was in some neighbor's hands?

They may or may not demand payment and may or may not threaten to take you to court.

This is frustrating but not life-threatening.
