If it is legal, marijuana production is a perfect use case.

The Trump administration is slowly moving in the direction of a crack down on marijuana. 

I'm not sure what the marijuana laws are where you're at, but here we have a lot of people that want to open medical marijuana dispensaries, but most landlords don't want to lease to them because it's such a grey area legally.

It takes 1 million to buy 20 acres and a home around me and unless your growing CA newest cash crop (marijuana) whatever you grow will not pay for the land so I need to come up with a way to sustain the purpose.
