This is gonna be one of those odd ones you’d have to ask the agent about. It’s 28 acres with two homes on it, one of the homes doesn’t convey (as in, it will be removed from the property before closing). Possible that home was originally meant to convey. When you have acreage and multiple homes and possibly multiple listings for different configurations of how it is being offered the pricing history can look strange. There are often valid reasons for the way it looks on syndicated sites because of the way they pull listing information.
