Does anyone know of a company where i can insure my LLC and get an umbrella policy

[Raza Rizvi]

I have a coop in Manhattan that is a primary residence and a 2nd coop that is a rental. I also own a rental property in AZ and in the process of buying a 3-family home in NJ (closing next week).
I was on regular insurance policies but now with the new 3 family unit I feel it is time to move them to a LLC. The AZ and NJ properties have no mortgage so they can be moved to the LLC without any issues.
The question is how to structure the Insurance. Do I insure the LLC? Get an umbrella policy? How does it work? This is all so confusing. Please help!! Thanks in advance.
