I used to think a handshake with the neighboring landowner was good enough to cross their property to reach a landlocked parcel. Watched my uncle buy 40 acres in Cocke County that way back in the nineties. Neighbor was friendly, nobody cared. Then that neighbor sold, new owner put up a gate on day one, and suddenly my uncle had 40 acres he literally couldn't reach without a helicopter.
I almost made the same mistake myself a few years back. Found a sweet chunk of ridgeline perfect for camping and riding. Seller assured me the folks next door were easy to deal with. Maybe so. But 'easy to deal with' doesn't survive an estate sale or a divorce settlement.
If there is no deeded easement recorded at the courthouse giving you legal ingress and egress, that land is a liability, not an asset. Doesn't matter how friendly everyone is today.
Anybody here actually successfully negotiate a recorded access easement after the fact once a new owner locked things down?
