Maybe your new PM will be able to clearly lay down the law to the tenants and bring about change in their behaviour?

You can use facebook's algorithms to find like audiences that have similar behaviours and characteristics to those that have previously shown to be motivated, but as you can see... this is not at all what you were asking about right?

There is zero tolerance for emotions in dealing with tenant behaviour.

Who cares that they are misrepresenting the truth and lying through their teeth - this behaviour would be consistent with their other actions. 

Telling me that their 50 pound dog is well behaved is one thing (my ad states 1 pet less than 20 pounds), but seeing its behaviour for myself tells me so much more.

It's no different than any other inter-personal relationship and often one must go through several bad relationships before finding a good one.

Yes, your time has been wasted, and BP scolds such behaviour.
