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, 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 with its variables, constraints and scenarios is presented. The authors present verification of the model made during the worldwide financial crisis in the year 2008, follwed 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 outline for future work.
