Verification and efficiency analysis of an algorithm for similar properties
(2013) Basista, Izabela
The value usually sought through valuations is market value, and its establishing is preceded by analysis of real estate market, in particular as regards obtainable prices, rent rates and transaction conditions. Moreover, the market features of properties are defined that have the most significant influence on the properties´ value. After the analysis of a real estate market, the next stage is to select properties similar to the valued properties. According to the Land Administration Act, a “similar property shall be construed as a property comparable with the valued property in terms of location, legal status, purpose, usage and other features that influence its value.” Nevertheless, the legislator has not defined specific manner for selection of similar properties. This is the reason why real estate appraisers have certain freedom with selecting similar properties in the valuation process. In practice properties are deemed similar when most of the attributes which describe them are the same. This study offers the result of a verification and efficiency analysis of algorithm designed for the selection of properties most similar to the valued property. It is based on price-determining indexes calculated for each property in the database and for the analysed and valued property. The algorithm allows for the selection of similar properties at the confidence level defined by the user, which constitutes additional information about the group of properties selected from the database. The exemplary database shows how the algorithm works. Its effectiveness has also been measured, and the results have been included in the final part of this study.
