The Nearest Neighbors Appraisal Technique: An Alternative to the Adjustment Grid Methods
提出一种新的房地产评估技术，通过单一指标捕捉所有可比差异，消除传统调整网格方法的主观性和逐项调整，实证表明其准确性优于调整网格法和特征价格回归。
This study presents a new appraisal technique, dubbed the Nearest Neighbors Appraisal Technique, which vastly reduces the subjectivity of the traditional adjustment grid methods while eliminating the need to adjust for subject‐comparable differences on a piecemeal basis. Any number of appraisers who apply this technique to the same property at the same point in time will get the exact same estimate of value. The technique avoids piecemeal adjustments by capturing all subject‐comparable differences in a single measure. Using single‐family sales data, the technique is found to be more accurate than any of the adjustment grid methods and hedonic price regression estimation procedures.
