Dedução do fator área utilizado para o tratamento de dados amostrais nas avaliações imobiliárias: um estudo para de terrenos urbanos na cidade de Uberlândia/MG.

Abstract

This study aims to deduce the area factor for urban land in the city of Uberlândia/Minas Gerais, such factor is commonly used in real estate valuations through the equation presented by Engineer Sérgio Antonio Abunahman in his work “Basic course in legal and engineering engineering assessments". ABNT NBR 14653-01 and ABNT NBR 14653-02 impose restrictions on the use of factors for the treatment of data obtained in market research, according to the standards, the factors to be used must be periodically disclosed by renowned institutions or deducted by the evaluating engineer, in most cases the factors used are based on bibliographical references only, thus not meeting what was requested. The methodology used to deduce the area factor will be presented in the article "Dedução do fator área em unidades padronizadas: apartamentos " by the author Marcos Mansour Chebib Awad, a market survey was carried out in which the elements had characteristics as similar as possible to the paradigm situation, from then on the data were processed to isolate the area variable, thus obtaining the unit value variation in relation to the area variation. The study defined an exponent of 0.05 for the expression of the area factor, different from that provided by Abunahman, which was 0.25 or 0.125, depending on the area to be evaluated. We can conclude that the variation of the area in urban land in Uberlândia represents a smaller variation of the unit value in relation to the expression provided by the established literature.
