My parents recently inherited my grandparents home and property, and sold their home to move in. It's great land in a wonderful suburb, and the home is being upgraded by them as well. The land is 17 acres, grassy, and flat throughout.
My parents aren't into mustachian things, so they're likely not going to sell any of it, but they were considering using some of it to make extra income. Some options that came to mind:
1) Cell phone tower leasing
2) Leasing out to a farmer who needs additional land for growing crops
3) Growing their own crops, as long as it's not too time intensive (they are both still working)
Some things that may be out of the picture.
1) Billboards. It's adjacent to the interstate, but our city ordinance does not allow billboard on res or agri land.
2) Selling any of it.
Any other ideas? I would be happy to put some time and effort into helping them, but I'm pretty clueless where to begin. I think the cell phone tower leasing option is attractive, and my grandad was once approached about it, but I have no idea if that ship has already sailed.
