You will also likely want to have a single broker for all of your insurance. As an owner, it's usually nice to have things harmonized to one renewal period. Talk to the broker about Director's and Officer's (D&O) insurance and also make sure you've asked the seller about any federal, state, city, or county required insurance that is required to maintain your license. Our state just added cyber coverage as a required insurance to operate.

Agree this should be your insurance broker. After having gone through this, I would definitely be charging the seller additional fees for this beyond the cost of the insurance - it will cost a TON of your time and a lot of legal as well.
