A computer implemented, interactive method and system for assisting real estate agents and their clients in managing and closing a real estate transaction. The invention includes the computer system's generation of a Gantt Chart which automatically tracks the entire real estate transaction, simultaneously providing each agent with the same visual presentation, on their own computer display device, of a description and status of each task to be performed by both agents in order to close the purchase and sale of a property. The Gantt Chart displays each task in a column on each agent's display device and adjacent to each task is a horizontal schedule bar which may contain at least one status indicator which indicates the status of its associated task. A document access indicator is also displayed as an icon adjacent to each task which involves the preparation and delivery of a real estate document. The agent selects the icon in order to display a desired document on the display device, and when the document is completed and delivered the Gantt Chart is automatically updated to indicate that the status of the task has changed. The Gantt Chart also provides each agent with access to a list of vendors to perform a task involving the utilization of a vendor service. As the agent and the selected vendor interact, the Gantt Chart is automatically updated to indicate the current status of obtaining the desired vendor service. When all tasks have been completed, the computer system achieves the complete history of the transaction and generates a pre-closing report. The system also provides each agent with the ability to simultaneously monitor and perform tasks for multiple transactions.
