I follow land prices and values pretty closely in SE Iowa, and have been doing so now for about 20 years. While I am not a professional in the market, I do have quite a bit of information built up over the years. Given that, here are my thoughts...
The old real estate maxim...location, location, location is still very applicable. In particular, the neighbors to any given property are super important as to whether or not that property can realize its' potential and in some cases nowadays, prospective buyers are actively researching the neighbors as much as they are the property they are looking at. (This is very wise IMO.)
Sort of along those lines AND also because some property owners have worked their tails off over many years now to "trick out" their land to be as well prepared to benefit wildlife as possible...I now see another "segment".
In my mind, there are four primary segments now:
1. Ag ground - this is primarily tillable, with possibly some hunting, but true farmers are the likely buyers here. This ground spiked 2-3 years ago and has now softened, and if grain prices continue to be lower it will drop some more I think.
2. Recreational ground - this is predominantly timber/brush, often with some pasture and/or tillable on it too. This is the ground that so many of us hunters have bought in the last 15-20 years, often very cheaply as the return on the land for a farmer was very poor. 20 years ago = $275-$350/acre. 15 years ago = $750-$1000/acre. 10 year ago = $1200-$1800/acre. Now = commonly listed for $2200-$3000/acre, although sometimes selling below that in some situations.
3. Mixed - a combination of ag and rec.
4. Premium rec ground - this is my "new" segment.
I know of one farm that sold recently that brought nearly $4000/acre. (Yes, there was a small 1 BR house on the land too.) But what drove the price on this place was that the seller has worked like a mad man for many years now to enhance the value of this property from a wildlife perspective and it sure appears that the buyer valued all of this excellent habitat work...because there is no way in the world he is going to make that land pay for itself by cropping or pasturing it.
Quick summary...I do not see the rec ground prices dropping much, if at all, barring a widespread economic problem. Right now, it is sort of a seller's market for good rec ground. Realtors are having a harder time getting listings in the good areas.
