Abstract: A system is provided such that automated real property valuation may be achieved accurately, rapidly, objectively and consistently. The application accepts information associated with a subject property, such as the street address, and then locates that property in an associated database. Following that, the application computes a valuation for the subject property based upon comparable properties, prior sales history and other factors and data inputs. The system of the present invention accesses databases as necessary for comparable data and automatically and systematically determines the most appropriate comparables to use in arriving at a valuation. Additionally, the system may be customized by various users such that the valuation process may be undertaken in connection with pre-determined criteria such as the number of comparables to use, the maximum acceptable adjustment and other user defined criteria.
