Hi, I have spent some time in your area, although I am not licensed in VA. I suggest you look up the local RLI chapter in VA. RLI is Realtor Land Institute, and is comprised of Realtors who specialize in land sales. I have taken several of my land classes through the RLI chapter in VA and met some really terrific and knowledgeable people. 3 parcels of 18 acres each in your area could carry widely different values. There are a lot of factors to be considered. I put a link for VA chapter of the RLI below. If you want help locating a specific agent, I would be glad to assist. I met several RLI members across the country and in VA, but specifically as I have taken several of my classes in Richmond VA, where the VA chapter meets. Even within land specialists, there are those who specialize in timber (one of the members I met there), those that sell horse farms, development land, transitional land, ag land, etc.
