But then, it's always understood that NONE of the rent/lease payments go towards the purchase price - until the Buyer exercises their Option by getting financing and paying out the Seller - or, losing their Fee by just leaving or continuing to rent, or, renewing their Option with its new Fee.

If the buyer hasn't exercised his option yet then the property still belongs to the landlord.

I've been doing basic number crunching and thought exercises on something like 20 x 2/1 units at ~1000 sq ft/unit and rent out between $800-$1000/unit in the Houston area.

The primary goal of this exercise is to give you added exposure to the lending or investing process during the early stages of creating a new business.

If you already "own" a third of it, what's stopping you from exercising your right to just go live in it, and make any monthly dollar adjustments that would still see the others get the same return on their two thirds?

Whatever you do have a termination notice built in that you can exercise fast if things do not work out.

It's not that I have a million dollar house or anything like that, I was just trying to pin down if I could include the value of my house to my other assets to obtain my actual net worth to be a millionaire.Stupid exercise I know, but hey, I like doing the math, and I believe in keeping track.

By house hacking, your expenses are ameliorated (to less than rent hopefully), and you wouldn't need to repeat the exercise after a year unless you wanted to scale your investments quickly.

Telling people they need to eat less, exercise, and gradually reduce the leverage in their real estate portfolio isn't very popular, but it is good for your overall health long term.  

The only time this would matter is if you're business fails and you're trying to get out of paying your lenders by exercising your limited liability.
