Determinanty wpływające na obniżenie wartości nieruchomości mieszkaniowych na rynku wtórnym

Abstract

Determinants causing the reduction of the value of residential real estate on the secondary market. Purpose: The aim of the study is to determine the impact of noise, treated as a phenomenon accompanying transport infrastructure, on the market value of residential real estate. Design/methodology/approach: The article presents a study of the seasonality of phenomena, which makes it possible to determine their cyclical character, e.g. price jumps on the market taking place for a specific period of time. The analysis of the dynamics of these phenomena allows to show changes in the economic situation, e.g. an increase or decrease in the price for 1 m2 of living or usable space. Additionally, the authors have also included a study of the interdependence of phenomena (correlation), which made it possible to determine the interrelationships between the phenomena (or their absence), i.e. the impact (or no impact) of noise on the price for 1 m2 of flat area in dwellings located in the civil or military flight zones. The compilation of the obtained data has been combined with the analysis of the structure of dwellings in terms of their area, floor on which they were located, number of rooms, as well as the age of the building. Findings: The conducted research has shown that noise is an important price factor on the housing market. A number of residential real estate offers have confirmed the relationship between the falling price and increasing noise, and vice versa – the lower the noise level, the higher the price. However, the amount of research into the effect of noise on the price still seems to be insufficient, which makes it difficult to forecast the impact of the noise level on the future value of dwellings. Therefore, it is problematic to determine the trend of such an impact. Originality and value: The noise factor is an important element not only in the decisionmaking process concerning the purchase of a dwelling, but also during investment activities carried out by developers. Locating an investment in the vicinity of a source of noise may significantly reduce the potential income from the sale of dwellings due to a drop in their value. Noise, which affects human life processes, is indirectly reflected in land and housing prices. The impact of the noise level on the decrease in the real estate value is determined by the noise depreciation index (NDI) or noise sensitivity depreciation index (NSDI). These indices show how a change of 1 dB in the noise level in the vicinity of a real estate affects its value.
