The invention relates to a system for managing real estate transactions that includes a database and an application server. The database is configured to store property data for properties listed as for sale by a broker, store a search criteria for a buyer, and store an address of a property listed for sale for a seller. The application server is configured to query the database for the properties that match the search criteria, store a first result of the query after the database has been updated, re-query the database using the search criteria to obtain a second result including data not present in the first result for at least one of the properties, where the data comprises a link to a map displaying a geographic location of the at least one of the properties, and generate a message for transmission to the buyer based on the second result.
