Distressed comps
研究了在住宅评估中使用困境房产作为可比案例的情况，发现它们通常是好的匹配，不会拉低评估价值，但会增加评估低于交易价格的概率，尤其对高价房影响更大。
Abstract We consider the use and impact of distressed properties as comparables in residential appraisals. First, we describe the incidence of their use and their relative comparability; second, we estimate their impact on the appraisal value itself; and third, we consider their impact on the probability that the appraisal is below the proposed transaction price. We find, generally, that distressed comps are largely good matches to their subject properties, which suggests that they are not necessarily used as a last resort. We find that they are not a drag on appraised value because appraisers learn to make the right adjustments over time. The use of distressed comps is associated with a higher probability of a below‐price appraisal due to the increased spread of appraisals around the contract price, particularly for higher priced homes. Overall, the use of distressed comps increased the uncertainty in the valuation process, but appraisers learned the appropriate adjustments over time.
