Appreciation of land is based on speculation; therefore, where do you look to fill your own intuitive drive on this investment? You could invest in raw land that you think is in the path of growth; however, that may be a long time to wait for profit since central KY appears somewhat resistant to urban sprawl.
In the past, investors have eyeballed developers to see where they are going with roads, electric and sewage lines. This may leave you fruitless because government plans change based on funding and the reigning regime in power. Regardless of what you do, keep searching for the answer because as Gerald O’Hara once said in Gone With The Wind is “The land is the only thing in the world worth working for, worth fighting for, worth dying for, because it’s the only thing that lasts.”
