Abstract: A system for negotiating pricing for a rental property includes a first client device in communication with a global communications network to be used by a prospective leasee of the rental property and a second client device in communication with the global communications network to be used by a leasor of the rental property. The system also includes a server in communication with the first and second client devices via the global communications network, and a database stored on a memory of the server having information stored thereon. The server is adapted to receive information from the first and second client devices to be stored on the database and to be transmitted between the first and second client devices via the global communications network.
