One way to frame this to make it sound more juicy/safe to your potential investor, is you separate the two relationships.
You pay regular rent, traditional tenant -landlord situation.
But then they pay you to be their on-site property manager and caretaker. Traditional property managers charge 10% of the rent for doing very little (ask me how i know!.. or not. Grumble), if you’re onsite and doing all the greeting and cleaning work, you could justify a much higher %
The investor has your steady rent to depend on, plus they know you have an incentive to keep things looking good on the short term side.
Another way of doing this is going into a true partnership with someone and forming an LLC. When you draw up the papers you can stipulate what each person is contributing (they’re contributing capital, you’re contributing knowledge and labor) and what % of the profit you each get as a result. Then whatever rent you might pay goes into the LLC and you get a % back once a profit is made. (That takes a while because property is expensive…)
Anyway, i am not a lawyer I’ve just been reading and thinking a lot about how to make long distance rentals work for landlord and tenant. :]
