I live on six rural acres and own the adjacent lot, also six acres. My neighbor on the other side of the lot wants to buy it, but I don't want to sell it to him. His property is 'junked up' with inoperable vehicles, an uninhabitable mobile home, and various pieces of equipment scattered around. Fortunately the views of the mess are mostly hidden when the trees have leafed out. I believe that if he buys this lot he will expand the mess onto the new property where it will be plainly visisble and this will have a negative effect on the value of my house. Do I have to sell to him if he makes a reasonable offer, or even offers full price?
