A computerized system and method uses a central server to aggregate data from a plurality of data sources and presents such data to potential property purchasers. Users are assigned a dedicated e-mail address that is associated with their user account at the central server. Users can then review unaffiliated property search websites to discover information about a property. Using the sharing mechanism built into the property search website, an e-mail identifying the property is sent to the dedicated e-mail address. This e-mail may contain user comments or other useful data from the property search website A server receives the e-mail, identifies the property from the e-mail, extracts information from the e-mail, and stores this information in a central database. The property identifier can be used to extract additional information from other locations. Users can then view aggregated data through a user interface presented by the central server.
