Eventually I hired my own HVAC and fixed it for good.There are many other occasions where they would not communicate with me nor tenant on getting certain issues addressed like leaking sinks (which damaged the cabinets and had to be replaced), broken ac, etc.At what point do landlords have grounds to sue a property manager?

In any occasion, best of luck out there!

In a B neighborhood, cash flowing turn key house hacking opportunities are rare (although do exist on occasion), but I do see better opportunities with properties that need some work. 

I use them on occasion for the notes and properties that I have in 31 different states.  

The rental property calculator has come in handy for me on more than one occasion.

But on the one occasion I was able to get a hold of someone there, they told me that I am "probably not going to see my money back".So, my questions are: 1. what are my options at this point?

I can probably share some pain points that I find investors running into in many occasions.

I’ve called the police on several occasions to increase patrol in the area. 

It was a very momentous occasion when I renamed the Marketplace forums

It's not NYC, but 40 will resemble the L.I.E on occasion.
