I live in a small condominium building in Massachusetts, and someone bought the building next door and is changing it to apartments. The buildings are only 4.5-5’ (feet) apart at the rear. Each of our deed surveys show the property line to be 1.5 feet from our houses.
>I'm not following this. If there's 4.5-5 feet between the buildings, then a property line exactly halfway between the buildings would be 2.25-2.5 feet from each building. Are you saying that each of the two surveys depicts a different location for the property line? If so, obviously one of them is wrong (or maybe both are wrong), unless there's a skinny sliver of property running between the two properties that some third person owns, which would seem to be rather unlikely.
