The aim of the paper is to build the model which might help to predict the number of mortgages sold on the Polish Internet market. Due to the specificity of this market, the great number of variables, also linguistic ones, influencing the market, traditional models and statistical methods proved to be improper. Thus an attempt at constructing a model integrating the traditional (analytic) approach with the soft (fuzzy) one was undertaken by the authors. The first part of this paper presents the description of the market. Next the rule model of the Internet mortgage market with its variables, constraints and scenarios is presented. Then authors present verification of the model made during the worldwide financial crisis in the year 2008, followed by the presentation of ideas for changes that will have to be introduced into the model. The last part of the paper consists of conclusions and the outline for future work.
