A Mortgage Location Survey is not a boundary survey. It is merely a surveyor’s opinion that the buildings and major improvements “appear” to be located on the property described in the deed. Many lending institutions require this inspection to check for various problems with the parcel such as encroachments, zoning violations, and the need for flood insurance, but it does not determine whether the boundaries, as described in the existing deed, are correct. Mortgage Location Surveys are commonly required for residential properties.
