That might not be the best use of your time if you don't have a financial background.

My goal is to be financially independent working for myself.

The situation was very similar to yours.

I have scaled teams from 2 to 1200 team members, developed leaders, managed businesses and financials, and more.

I am looking for the passive income and financial freedom. 

No unregistered vehicles and no vehicle repair on property is in the lease (although I wouldn't have a problem with emergency battery and tire situations, I prefer they don't change the oil on the property. 

I have not house-hacked, so take this with a grain of salt, but I am thinking about it from the financial perspective, and it's analogous to owning a two- or three-family house, where you live in one of the units and rent out the others.

What are your favorite real estate/frugality/financial independence strategies?

Recommendation would be to have a professional look over your situation.
