I have a house that needs some work that Im selling as a handy man special. I buy and sell house for a living and have done this for years. But the guy that owns the property next door and around the house keeps coming over when the realtor is there with a potential buyer and saying there is a million things wrong that really are not. What can I do about this. he has ran several people off doing this. Is there any laws that prevent this. i have no trespassing signs up now to maybe detour him from coming around.
