摘要

摘要本文介绍了一种新的房地产估价销售比较模型，该模型可以客观地估计与解释价格变量相关的系数。价格调整过程的系数由类似于投资组合选择问题中的均值-方差模型的二次规划模型的公式估计，并显示与要评估的财产无关。研究还表明，销售比较模型应该使调整后价格的方差最小化，而不是像一些国家和国际估价条例所指示的价格的变异系数。本文最后以哥伦比亚Medellín市为例进行了研究。

A Mean-Variance Optimization Approach for Residential Real Estate Valuation

Abstract This paper introduces a new approach to the sales comparison model for the valuation of real estate that can objectively estimate the coefficients associated with the explanatory price variables. The coefficients of the price adjustment process are estimated from the formulation of a quadratic programming model similar to the mean-variance model in the portfolio selection problem and are shown to be independent of the property to be valued. It is also shown that the sales comparison model should minimize the variance of the adjusted prices, and not their coefficient of variation as indicated by some national and international valuation regulations. The paper concludes with a case study on the city of Medellín, Colombia.
