Does anyone have any insurance companies they've used for insuring a mobile home community with a lagoon?

We strongly urge tenants to have insurance to cover these types of situations.

My company also provides insurance, 401(k) matching up to 4%, 2 weeks PTO that can be used immediately, profit sharing ($1200/year), and weekly bonus/commission opportunities.

I suspect when these are done and ready for lenders policies the title companies will be very picky on issuing insurance . 

When they book through Airbnb, you have some protection/insurance through Airbnb to protect you if things go wrong (although I know many people have had issues when that actually happens).

I'm guessing you didn't go through insurance, but you should simply let your insurance provider know that you got a new roof (don't need to say why other than it was older). 

perform deprecation (most insurance companies require you to do this anyway) Repairing a fence damaged by wind or rotting is generally considered maintenance, not an improvement.

Even though they maybe “out of service” many insurance companies will not insure if they are present.

-The rehab has it's own liability policy that I believe will add me as a named insured (I need to verify this.)

The taxes, insurance, legal, upkeep, vacancies will drive you nuts if a few hundred dollars ruins your day. ;-) When foreclosures are common, (which they are not right now), I send out two thousand letters a week.
