An asset information management system is provided to facilitate investment information gathering, managing, trending, and sharing of information. In the preferred configuration, at least one computer system is connected to the Internet or other data source via a communications device. The communications device provides electronic data such as public data, market forecast data and parcel historical data based on search criteria. The electronic data can be combined with user information to create output charts, graphs, and reports including market trends, forecasting, and current valuations. The system also provides a function to exchange and/or compare information from two or more users toward buying real estate, selling real estate, exchanging real estate assets, or to offer advice on a valuation. Additionally, the system can be attached to a mapping system such as GIS, or satellite mapping. This invention allows investment messages or advertisements to be sent and received to an electronic device or many.
