Only use the US Post Office assigned address. Where none exists, use the tax record (usually only needed for new construction). Care should be exercised in determining whether a compass point precedes the street name, appears after the name (MLS=Post Direction) or is included within the actual name of the street.
EXAMPLE: South 17th Street in Wilmington: Name=17th. South=Direction.
EXAMPLE: Clancy Drive Northeast, Winnabow NC: Name=Clancy; Post Direction=Northeast
