Try to avoid conflict or confrontation as he could really cost you a lot of money and grief.

Nothing good is going to come from you confronting the neighbor unless you happen to have a good relationship with him, even then I would stay out of it.

@Patricia SteinerHmm, I'm very confused by your unnecessary confrontation.

Thanks to those that gave insightful information without going nuclear on the political spectrum.I must apologize for helping this go off track but I will always confront what I deem to be sheer ignorance.

By the time he got off the property he was confronted by a tenants friend that knew he was the OWNER picking up rent. 

This often includes physical rent collection and confrontations.

In my opinion avoiding a conflictual confrontation will save me money (in my market), so that is my strategy.

Everybody saves face, no confrontation - but you called her bluff.  

I confronted him the second time and he says he is burning incense.  

Two months later, B has no job, and A confronts him  A and B have a fight, B threatens A and A is forced to move out for safety concerns.
