I'd say I was worried, but there's not much to do about it. I've just watched ag and dairy dry up over the last quarter century as farmers in my state chase anything that will give their families security, even if it means being paid not to produce, not letting their children learn the business, or selling off land.
A huge intergenerational transfer is imminent. What the grandkids will do with eighty acres in Iowa is anybody's guess.
80 acres is a Vermont kind of operation. Eating crops. They're around.
Meanwhile, a few here and there will be snatched up by people from coastal cities who have made enough to FIRE and have romanticized farming. They won’t grow significant crops but will raise a few chickens and goats and a garden full of cabbages and peppers.
If you had the right background and resources, you could probably make a killing buying up 80 acres for a pittance, carving it up into 5- or 10-acre plots with modern amenities (upgraded plumbing; solar; excellent internet) and pre-built facilities for small numbers of farm animals, and selling them off to that market with the value-add of instant community.
It could be done, but it is not just re-drawing some parcel lines and calling a realtor. Even once you get it done, you now need to build somewhat expensive homes to recover your costs, and the FIRE folks will then probably buy that century farmhouse down the street and re-parcel the connected field to keep a few acres for themselves and sell the rest to the neighbor, as they can almost get a house in the country for free if they do so.
Not sure the dynamics of Iowa of course, so it could be different...but I do not live in a particular big or interesting area, either.
