I personally think the less than 100 acre farms (tillable or no tillable) high prices are here to stay, especially anything 40 acres or less. There are more people that have cash (from no longer wanting it in the market) and want to own dirt. not even for hunting or farming, but to own land, or to live on or what ever the reason. And I dont think many of them look at the "per acre" cost. I know many that have "X" amount of liquid, and they have simply looked for a piece that falls in line with that budget and buys it.
If I owned a large parcel that had lots of access points along roads, I would log it and then be breaking that up into small parcels in a heart beat to list. woulda coulda shoulda bought in a 30 mile bubble of the DSM metro years ago.
