There are a quite a few states where this does pencil out to be be profitable. I've ran the numbers on a NM property that I almost bought last December. We put an offer in on that one and just couldn't come to an agreement on the elk tags (go figure). The seller wanted to keep them for the next 10 years as part of the deal because that is what the terms of their arrangement was with an outfitter and unfortunately that was what made the property have the selling price it did. We countered and offered them 100k less to have them keep the tags for 10 years and they thought we were joking. 1 Bull tag at 5k and 1 cow tag at 2k per year is 7k x 10 is 70k. Add in 10 years of interest and likelihood of those prices going up. Apparently they couldn't do math.
The property also was leased out for grazing. We didn't get a real value for this specific property but figured we could get a couple thousand a year for that especially since the property had year round water on it.
I also ran some numbers to do it on a parcel here in WI and it absolutely does work out. People are crazy here for their whitetails
