Aplicativo piloto para la consulta de precios de inmuebles y avalúo rápido de acuerdo a variables espaciales en la ciudad de Bogotá

Abstract

This paper presents a rapid real estate valuation and query system through a web application prototype for the Usaquén locality in Bogotá. The use of hedonic prices and market comparison for apartment price estimation in the study area. A linear behavior of intrinsic and spatial house price components is assumed so variables implicit prices are calculated with OLS method. Six valuation models where analyzed comparing 65 variables of 1096 on sale properties, in the best-case scenario a 9,27% medium error was obtained. An approach error on distance towards spatial variables was evidenced as well as noise on results due incomplete data management on intrinsic variable processing. The least error model was implemented on a web application that allows sale price valuation, urban services and on sale properties query.
