Letter also to the HOA regarding the incident (s) history, asking the HOA to draw up better guidelines for assistance and how to keep the peace, she'll have to explain to the others on board what her plans are for this.. pressure where you can..

It has not been a totally negative incident.  

I do not think my insurance company would foot the bill for the entire incident.

LLC basically protects you from losing your primary home or other assets in your personal name due to an incident at a rental where someone wants to sue you.

If no complaint was issued inform the animal control officer of the dog bite incident and say you want it investigated.

Of course do this only if family does not step in and you have contacted them yourself.Explain to all the nusicance calls to 911 for emergency assistance and you could inform police if this type of incident repeats itself maybe then should send out an ambulance for transport for mental health evaluation..could be person if off meds, but this behavior is not normal, average, and is beyond you call as to discipline. unless he starts yelling, or causing disturbance which you should make notes of.. 

It would cost me more than my car is worth with this kind of coverage because of my age and an incident on my driving record a few years ago.

What is the probability of being sued for a major incident that could wipe you out or cause significant losses?

Do you know if my insurance policy will step in and represent me on my behalf and cover the losses since the incident stems from an injury on the my property?

In this little patch around the highlighted area you've only got 4 incidents of violent crime in the last 6 months.The area you're looking in is a lot less dense in population, and has more of a rural feel to it.
