There are a variety of carriers that will do this sort of risk however there are several options.

Hi Owen,There are a handful of carriers in FL that write short term rental insurance.

I looked into that but my insurance agent said the carriers would not insure an arrangement like that.

so if i am understand what you have here 25121 is noi before paying anything on loan to new park owner. if above is correct then loan amount if price is 390k - 80 k down= 310k   @6% 30 years =1859 x 12=$22308=2813 profit yearly2 check with insurance carrier i am sure you can but cost may be to high 3 selling units to park renters may be a good way to go but if on a fixed income they may not have the money to do so and now they have the cost of insurance .4 check with local appliance repair as to service i would collect the money myself. if park is 55 plus upkeep may be minimal 5 i would ask for 30 and not offer any points 

Hoping they take care of their clients better.Be sure to check with your insurance carrier on coverage.. did you go into the same low end neighborhoods ?? 

You don't have the authority to indemnify others and have it covered by your insurance without the express written permission of your insurance carrier.

That will require the insurance carrier to notify you if the policy is cancelled for any reason including non payment.

Payroll for the year (it is normally subject to audit at the end of the policy term)You can normally add coverage for your tools and equipment.Most of our carriers have a minimum annual premium in the $500 range.

They KNOW STRs in this region.As far as an umbrella policy covering both your STR and LTR depends on the carrier and and their rules.  

There are many carriers and Programs available for vacant and renovation policies.
