Thanks for all the great info!

I would it up Goosehead for a broker that can get you someone, or hit up a fix/flip person in your area that would give you that contact.

How do I contact and advertise to hospitals?  

Apparently this Master Plumber on record for the co had used the cos ins info and name to pull permits for my job but he didnt really do the job thru the co he worked for.

The problem we have run into on Zillow or Redfin is that when we find a company or person that purchased the property, it is really hard to contact them. 

If we can find their landlord by reversing the address and contact them on a number we find or via Facebook we do that and often get the real story this way.

@Ryan StuckeyOK, thanks for the info.

In New York coop unit is a purchase where you have to provide all your financial info to the board Memeber which is also your neighboresI am worried that my neighbore knows that I own 20 unit rentals and look into details of my finance.

In the mean time, I would contact a local real estate lawyer and see what can be done. 

He already contacted me.
