Abstract: A system and method for allowing a plurality of Sellers of real estate to either list their real estate “By Owner” or “By Agent.” Those Sellers that list “By Owner” may select a time period after which their property may be converted to a “By Agent” listing. “By Owner” Sellers may choose to “push” their listing to only Agents that specialize in selling a particular type of property within the geographic region of the property. Agents may also offer their services to “By Owner” Sellers that have listed properties matching the Agent's specialty. Real estate Buyers may, through a single interface, access all properties that meet the Buyers' criteria, whether listed “By Owner” or “By Agent.
