Since I'm paying cash and will have no mortgages, sounds like about 6-9 months gross rent should cover it, I guess.

Can it cover Multiple properties and does it come a lot cheaper than having Landloard Insurance (Covering Fire, hazards, Wind... ) ?

The pitch sounds good: I can rent out some vacant land for camp spots with essentially no improvements, and they cover the rest, and I keep 90% of the revenue.

That may only cover your original loan. 

I usually just install a CO/smoke combo on all floors while making sure they sleeping area one(s) cover all and that works just fine with the inspectors.

This is nothing new regarding concept, What I think will change is if they were to become mainstream it is the current Wholesale community will suffer a little because these guys are cherry picking the better properties and leaving the riskier properties for everyone else.

And the seller has the ability to foreclose if the buyer misses payments, again, unlike a subject to.As far as terms on the wrap, you want to be sure that the terms of the warp cover any situation where the buyer pays off the loan early. 

Either you are mistaken about them taking 15 year notes, or they are getting more in rent than you believe, or they are not putting anything aside to cover any incidentals and are "winging it".
