If you would like me to find an agent for you in that area, I would be happy to do so, but yes, you need to find a local agent to help you

It is best contact an appraisal, MLS only awards real estate agents opportunity comp residential homes, not rural, land, or commercial.

Go to the web and find a real estate agent in Gladstone, VA or one of the towns near Gladstone. If you find a broker's website, call the broker's office and ask for the agent on floor. Floor agents are looking for business and will be glad to help you find that price range. I have a long time client here in Tucson who has land in Lake of the Ozarks, Missouri. She used this method and has listed her property there for a fair price. When the market for land rebounds, she'll be in a good position to sell.
