The article presents the application of fuzzy modeling to solve the systemic task of qualitative assessment of the properties of land plots by an expert method using fuzzy modeling. The set of factors by which the suitability of the plot is estimated depends on the goals of the development project. The technique includes the decomposition of the model into additive models of internal and external factors and a combining multiplicative model, which reduces the dimensionality of the task of assessing the properties of the plot. At the second stage, a fuzzy model of expert assessment of the properties of land plots is formed. It includes a fuzzyification block using linear membership functions, max-min fuzzy inference technology, and defuzzification using the height method, which most adequately translates fuzzy expert assessments into clear numerical (point) values. At the third stage, the contribution coefficients of each factor in the assessment of the properties of plots are determined using the hierarchy analysis method and the fuzzy pairwise comparison scale.

The above study is aimed at calculating the market value of a land plot free from development, located in the city of Vsevolozhsk, Leningrad region. The authors consider a comparative approach to the assessment of the object, its positive sides and disadvantages are indicated. The features of the implementation of the method of comparative sales and the construction of regression models are noted. The dependence of the cost of land plots on the distance from the local center in the territory of elite cottage development was revealed. Vsevolozhsk. The conclusion is formulated about the influence of a set of factorial features and the method of their accounting on the reliability and compliance of the result with the current situation in the real estate market.
