The input data and their structure

The input data for those calculations is an array of information about the property under consideration, its geographic location, physical characteristics, and legal status.

All these data are used to search for analogs and to calculate the correction factors, the value of the object being studied, and similar establishments. Data can be entered by the user in text, numeric or selected from the reference books.

The heterogeneity of the data involved in the calculation of the expected cost of various types of real estate suggests their separation into two subgroups, namely apartments and houses, respectively, and applying the two algorithms calculate the result.

The data is inherently distributed according to the following criteria:

• data is entered in the information field for the descriptive part of the original form and shall not participate in the selection of analogs and calculations;
• the data are entered for a narrative, and participate in the selection of analogs and calculations;
• the data are entered for a narrative, and take part in the calculations, but do not take part in the selection of analogs;
• data that only take part in the calculations.
