Novus, you beat me to it.

There’s any number of ways to purchase various land or property holdings. Some better than others.
Around 30 miles south of me, there’s a private camp for sale.
Multiple buildings, dining hall, etc. One could both keep it stocked for private use, while making a few bucks and fixing it up while writing it all off.

One friend owns half a dozen small farms.
He rents the farmhouses out to various screened people for a pittance, just to keep them secure and maintained, while renting out the ground to neighboring farmers.
He keeps diversifying, one farm is now raising christmas trees and pumpkins every year. The local FFA does much of the work and gets something like 80% of the take.
