A method for generating sales leads may include querying a listing database for listings within a selected time interval and geographical region, receiving a base set of listings, executing filters that remove listings for property currently for sale or that have changed ownership since the original listing date from the base set of listings, and obtaining contact information for listings remaining in the base set to create sales leads. Additionally, the method may include mapping data fields between the real estate listings database and a local listing database, and providing a database adapter to migrate listings from the remote database to the local database according to the data field mapping. A system and apparatus corresponding to the above methods are also disclosed herein.
