It is incumbent upon me to have enough knowledge and experience to make sure I don't under-insure my policyholder (in the event of a claim) or to over-insure my policyholder (protect them from excessive premium). 

., AM Best rating, internet reviews from actual policy holders, etc.).

But to say an insurer is not reputable because they are protecting every other policy holder that they insure (as they are a mutual so every policy holder is an owner) by underwriting a property is not correct.  

I would think that if the owners who own the insurance policy came to an agreement with their insurance on the amount of damages before the sale to someone else, then the insurance company could likely agree to issue the check directly to the contractor/buyer, or the policyholders could just agree to turn those funds over to the new buyer as part of the sale.    

I need to purchase a Builder Risk Policy under a LLC but all the agents I have talked to can only insure under my own name and add the LLC as add'l policy holder.

@Anja Wehrmann I started with Amica back in the "old days" when you had to have a referral from one of their current policyholders 25+ years ago (auto + personal home). 

Yes they can, but it is not the only reason they could offer a higher premium on the renewal.If your area has had a lot storm related claims, like wide spread hail storms, chances are all policy holders in your area will see an increase in premiums. 

Who will insure will depend on location and age of the building.Premium policy holders get placed into groups but they only accept nicer areas and newer properties.

@Natasha M. he is the policy holder, so even if he sells the house to you, he will be the one who gets paid.  

Keep it shady, everyone knows that insurance companies will go to any lengths and make policyholders jump through bizarre hoops to avoid paying out a full benefit.
