Pros and cons of adding PM to your insurance

[Joe S.]

So we have a number of properties that are managed by primarily to PM companies. Both of the companies adjusted their agreement where we did not have to add them to the insurance. We have one particular company that we are looking to add for a property that is slightly outside of the areas that the other to handle. As normal, they are trying to say we have to add them to the insurance. My wife is adamant that they will not be added to the point that we may not do business together with this new company.

What are the pros and cons?
