PROBLEM TO BE SOLVED: To provide a real estate management system where the variations of real estate prices can be known in time series and the real estate prices can be confirmed on a map, where these prices are visually shown on a display device. SOLUTION: A CPU 4 of a real estate integrated center C secures correspondence between the price data showing the prices of real estates sold from the real estate agents 2, etc., and the coordinate data shown on a map and stores these price data in time series into a real estate database DB. Then the CPU 4 calculates the area-based mean price data and the use-based area mean price data from the price data stored in the data base DB via an arithmetic circuit 6, secures correspondence between these calculated mean price data and the said coordinate data and provides visually the specific area-based real estate mean price data or the use-based area mean price data to the agents 2, etc., and the consumers 3, etc., via an input/output device 5 as the image data, for example. |
