We have multiple carriers that we shop around with and some companies are better than others depending on the needs of the client!

If the Navy has men working on nuclear subs and aircraft carriers within a few feet of those reactors all day why can't we make a power plant that is safe.Or do we have them and people are just unreasonably afraid of them?

However, finding an insurance carrier that is comfortable with them in a rental is a challenge.

Does your insurance carrier know this?

Since you seek a particular kind of seller, you may want to experiment with different types of carriers (what DM industry calls the envelope). 

Even if every flight with a 737 Max was scheduled for Austin it wouldn't cause a blip in our air traffic. south west got the other half :) or something like that and I was thinking they could be a major carrier in your market.. flights tend to be seasonal as well. 

Some carriers have restrictions on the number of separate renters.

Most carriers have femtocell options for improving indoor coverage.

(And your concern about nuclear bombs being walked over from Mexico can also be solved because the bomb carriers will not be able to hide among thousands of non-bomb carriers.)I actually think the war against illegal immigration is quite similar to the war against drugs.

I have a few xmas tree farms insured and I know that all of those insurance carriers would not be willing to have the policy overlap into a real estate biz.If the RE biz leased back the farm to you as a tenant, that could work.
