You have acquired these buildings and 5 acres in a po dunk town somehow. Maybe bought them, maybe inherited them, who knows and it doesn't matter.
This would be an ideal setup if you had an existing business there that needed the space like farming, trucking, dirt contractor, etc.
I can't think of any business you could do where you are selling anything to the local community that would work because there is not enough population and you are too far from things.
Maybe you could make something there that is sold online? There are lots of trailer manufacturers, pickup flatbed or accessory manufacturers, etc that are in BFE.
I can't think of anything you could have there that people would travel to. It needs to be something you ship to them or just sell the place and get something in one of those 75k cities.
