One incident was family pitt attacked 9 year old and bit in the face and she was blinded in one eye and disfigured.

My opinion is , i would forget about the incident, take the loss and move on.

In doing further research since the incident however (as a new landlord, in hindsight I realize I should have researched it sooner) we have learned that it's such a rare breed that it's not on most insurance companies radar, but is just as vicious/ferocious with a history of many fatal attacks and should be excluded.  

I guess I went to them first because every incident i've had has been handled extrememly well with USAA.

But even if it is break even or slightly positive, do you want a property thousands of miles away where you are one vacancy or one weather incident from a very negative situation?

So far they all enjoy riding without a incident as far as I know. 

If I (an apartment mgr) decided I had to break a window to enter an apartment, then I would accept responsibility and pay for fixing the window.I would advise you to have your sister document the entire incident in writing. 

Recently, I had a similar issue with unresponsiveness (this is not an isolated incident). 

In case, god forbid, anyone every tried to come after you for an incident that occurred at a property. 

What aggravates me about this situation is the HOA never communicated anything to me personally about the trash in front of the property until yesterday when I received an email of the incident and a fine and a required meeting with the board.My management team told me the trash from the rehab would be hauled away, not just left in front of the property in one of the two parking spaces.
