There are two types of ground in southern Michigan: Rocky glacial till which is usually forested, and clay soils which are "driftless regions" inbetween the woodlots. The glacial till makes for great recreation land, and the flat outwash plains make good farm ground. Prices can range from $5,000 per acre and up, with more expensive tracts having streams or lakes, or river bottom soil. It is more and more likely that inflation will intensify, so, unless you are selling a house to buy land, I would use the cash now to get the land. I did so in 2010 and did not regeret it.
