I have done that model and seen that model over the years.. one guys in INdy called Holdfolio did thisnot sure how it performed but chose the rights assets and proper management and that works.there was a guy in Ohio also that called him self MR> triple net.. he sold you a home then rented it back from you for a set fee then he leased it out in a master lease situation were he took care of everything.my model I used a debt instrument equity share model that basically worked like what your talking about but had a pref return no matter what was happening with the asset.. that put big onus on operator to perform..
