I would probably buy around 5 Farms for $700000 each around the world - then I would get these up so I can run them with only 1 or 2 other people so we can produce our own food. The farms I do not currently reside in I would borrow to people I know and trust so they can also live a happy live while I dont need it - we could than change over time so everyone gets to live in different places.
The rest of the money I would invest in small businesses and other investment vehicles that generate me passive income that can pay for things like healthcare and thing I cant make at the farm.
What a wonderful live.
