I understand your point. But you are not the one that will make that decision. It is the neighbor that has to figure out what is most cost effective.
Landlocked property will not sell at a price that accessible property will sell at because the buyer still has to spend money to gain access. That can be very significant.
Have you actually spoken with the owner and made a proposal? I suggest that you put a proposal in writing and send it to them.
Yes I have spoken to them. I even sent them a satellite view of the place and the part I want to buy. I have not told them about there not being an easement of record. They are still trying to decide on a realtor and what they want for it. I am going to let them approach me when the time comes that they need a deeded easement. None of them live in this area so it is hard to talk directly with them especially as a group. So we shall see.
