I suggest using and independent insurance brokerage that can access many different carriers.

Is it allowable to work with a brokerage while also handling some real estate investment deals independently?

Person X should consult their own, independent advisors. 

Nearly every independent donut shop in Southern California hides a story — a story that starts with an unlikely impresario, a Cambodian refugee named Ted Ngoy.

We both had to pass the quizzes, exams and finish the modules independently to receive the course credit.

Let's face it...we are not all independently wealthy.  

Typically, you get more independent tenants who value the property as well.  

I would recommend contacting several Independent Agents (represent multiple) companies in your area.  

Hi Michael,If it were mine, I'd:(1)  Boot the dealer; and(2)  Pay an independent contractor to clean the area and dispose of the waste; and(3)  Possibly vend it off due to the increased crime/burned down Police Station (lack of PD response) in the area.Good Luck! 

As for the insurance aspect, it's always best to get the numbers from an independent third party.
