It was sad to see.Turns out there were, again, heavily involved with heroine, perscription and other drug use.I was able to contact her son. 

I am wondering the type of tax treatment for vacation rentals such air bnb, vrbo etc.

This is like hiring law enforcement officers to focus on solely drivers who forget to use a turn signal instead of dealing with those driving drunk/running red lights/selling drugs/etc and making me pay for that cop to sit and watch me and make sure that i use my turn signal (or else).10.

This generally does not make a lot of sense to do.Bottom line is that a SDIRA works exactly like any other IRA when it comes to tax treatment, timelines, etc.  

If during screening you run a criminal background check do you screen for drug convictions, violent and or sex crimes and screen these people out. 

Roads cost $, waste water treatment cost's $, drinking water, parks, sidewalks, street lights/signs, on and on the list is VERY long of the services NEEDED to support population and, at BIG population, those expenses get BIG. 

I also would make sure the doctor/psychologist puts something in writing stating "(1) Pit Bull" is required for treatment. 

Hopefully not...Now a neighbor complaining about a tenant dealing drugs or doing something on the property that would endanger or encumber my ownership - absolutely I'll get involved because that affects me.

Turns out they had been stealing rent payments, selling off fixures in vacant apartments and the manager's boyfriend, he was selling some really heavy drugs from out of the complex.

Yes if he would be involved in the management in the LLC, then I agree with your treatment.
