As I see your choices are to (1) not buy the property. (2) buy the property and try to enforce the Write Off that says the County will require a new permit and a new septic system that conforms to current zoning and septic setbacks (would remove the system from your property) Or (3) buy the property and sell your neighbor an easement for the system. The value of which would almost be the cost of installing an entirely new system. The risk is will the County back up the Write off.
