A method for providing real estate data on an interactive map which provides an interactive map display over which various real estate data layers may be overlaid to provide information regarding displayed property parcels. The present invention generally includes a central communication unit and a user device communicatively interconnected with the central communication unit via a communications network. The central communication unit is adapted to periodically access real estate data from one or more data providers to maintain a data repository containing real estate data regarding a plurality of properties. The user device utilizes a software application to retrieve such real estate data from the central communication unit and display a user interface having a map showing a plurality of map tiles. A data layer may be overlaid over the map to provide the real estate data in an easy-to-read manner while exploring a geographic area on the map.
