A system and method for transacting retrieval of real estate property listings using a remote client interfaced over an information network is described. A set of real estate property listings is maintained in a structured database. Each listing includes a characteristics set describing property listing information organized according to property class. A remote client is interfaced in a dynamic search session via a communications link transiently connected over an information network. The remote client maintains both program code and data exclusively in a general purpose random access memory configured for both transient and persistent storage. A target characteristics set describing one or more such listings in at least one such property class is received from the remote client upon initiation of the session. The listings matching the target characteristics set from the structured database are identified. The listings are provided to the remote client upon termination of the session.
