Insurance Coverage Requirements: RE Brokerage vs. PM Company

[Amber Forkey]

Looking for some general guidance in the New York insurance requirement field for opening up a new real estate brokerage. 

To my understanding thus far in my journey, I would need to obtain Errors and Omissions insurance. However, my brokerage will be focusing heavily on property management so are there different insurance policies that are needed in addition to E&O coverage? I will not be employing anyone initially if that helps at all.

Still new to this so I'm learning as I go. Any help is much appreciated!
