AmRisk small market is a great carrier in Florida but you will need to use an independent insurance brokerage to access them.

Sometimes carriers even require the contractors loss runs so make sure they have those handy at the least.

All national and local cellular carriers are looking to get access to these valuable spaces to put up their 5G antennas.

New acquisitions are new to you and very rarely do carriers need seller loss runs.

Now I’m researching which carrier to ship my car with.

Larry, I'm interested if you ever found another carrier and if so who.

There are pro-sumer type of companies (which basically target residential home buyer and sellers and are not uncomfortable with investors) like SafeCo and Foremost, and then there are some pro-grade insurance carriers that would be good to pivot into once you've reached a certain critical mass.I'd recommend getting in touch with an insurance broker who is a competent investor themselves. 

Any recommendations for carriers you've used during a BRRRR rehab and have been happy with their coverage/cost value?

Yes, sometimes that can be a problem, but it is carrier specific. 

The property I am considering buying is zoned for cell towers and one of the carriers has expressed interest in the past in locating a tower here.
