>>1164225I have experience with this, OP!
1: Shape of property in relation to landscape: you don't want thin property. The best shape would be a circle, but of course that won't happen. You are left with the best shape being a square. At the center of the square should be the ideal camping/house site. A square of land where the best camping/house site is located near the edge isn't good.
2: Distance from your land to the nearest highway, airport, or oil well field. The further you are away from these things, the better the sound quality of your location. For instance, I live 5 miles, as the crow flies, to a highway. On some days, the humidity is just right and I can hear the traffic very loudly.
3: Types of neighbors: Are they people with lots of kids/grandkids who like to run ATVs all over other people's properties? Is there a main thoroughfare across the property for ATVs? People with ATVs who run across property lines without permission will not respect your trespassing signs and will cut all fences down in order to gain access. Children will cross property lines all the time, though catching them at it and scolding them does help prevent repeat offenses.
4: Hunting seasons: Does, the location of the property have a large hunter culture for large game (deer or larger)? Hunters tend to cross property lines readily. Fences and no trespassing signs can help a lot with this, though some may still trespass.
5: Water access: Is there a river or lake that runs through or boarders the property, respectively? Fishermen in boats and boating enthusiasts will be able to legally traverse those waters which may or may not disturb you. Fishermen on foot will also trespass
5: Property size: The larger the better for privacy. I would say that 10 acres is the minimum. I've camped on properties 600 acres in size and it is fucking awesome. However, 10 acres with all the considerations above should be all you need. 10 square acres can be a square 660' x 660' on the sides.
