In this paper, we investigate on-line fuzzy modeling for predicting the prices of residential premises using the concept of evolving fuzzy models. These combine the aspects of incrementally updating the parameters and expanding the inner structure on demand with the concepts of uncertainty modeling in a possibilistic and linguistic manner (achieved through fuzzy sets and fuzzy rule bases). We used the FLEXFIS and eTS approaches as learning engines for evolving fuzzy (regression) models and compared them with a property valuating method employed by professional appraisers in reality as well as with a classical genetic fuzzy system. The comparison was based on a real-world data set taken from a cadastral system including prices of residential premises within the years 1998 to 2008.
