No harm in listing the property for sale and building a potential buyers list, getting time to pre-qualify the buyers and perhaps get an idea of what they would pay and what finishes they would want.

You are likely to have a prescriptive easement anyway.If you tried to contact for weeks, and now you schedule the work on his property and you don't damage anything permanently, what's the harm?

Because the loss of an earnest money deposit (not to mention the time, emotion, etc) will be far greater than what we would charge up-front to run the extra (& now necessary) database checks, we have yet another example, in my opinion, of "consumer protection" actually harming people.
