The aim of the paper was to investigate in general the mass appraisal solutions worked out throughout years in chosen countries and compare them to methods adopted in Poland. Moreover, authors tried to propose the use of new methods for estimating values of properties: geographically weighted regression, spatial autoregressive models, regression-kriging, underlining their advantages both on theoretical and practical background. The case study research conducted on the example of Olsztyn City Warmia and Mazury Province, Poland has shown particular advantages of proposed methods. First of all the combination of them enables not only assessment of different attributes of property on its value but also presentation of the analysis results on different maps. Statistical models including spatial relationship can be successfully used in mass appraisal. One ought to remember that these are better tools than the classical methods only when one can notice spatial autocorrelation in transaction prices. This condition is satisfied in most local markets, although there may be exceptional circumstances when the location of the property does not affect its price. In that case, the models would be equivalent to the classical methods.
