Nice acre to build on in my county goes between 10-15k. Buddy just scored 10 acres for 78k, but its just a big hill but has a great hardwood bottom with creek.
Solar panel folks are buying stuff up, we sold 70 acres of old cutover that was only good for some ok deer hunting for $6250 an acre recently. The neighbors behind that property only offered us 1500 an acre a few years prior for it.
