Abstract
Using New Orleans foreclosure data, where each property has three appraisals (borrower, lender, and referee), we are able to investigate the factors affecting appraisal bias and accuracy for distressed properties. Unconditional analysis shows that on average lender appraisals are higher than referee appraisals, while borrower appraisals are lower than referee appraisals. Much of the bias could be explained by various client and appraiser characteristics. The relation between the client and the appraiser affects valuation bias. Customer employed appraisers tend to give more client friendly valuations than their court appointed counterparts. However, experienced and licensed appraisers render less biased valuations. The appraisal bias does not appear to depend on neighborhood and demographic characteristics. In addition, experienced and licensed appraisers provide materially more accurate valuations. Unlicensed, inexperienced appraisers have an error rate approximately four times worse than licensed, experienced appraisers.

Notes
Since the law uses the term appraisal, but does not require state licensing, we will use the terms appraisal and valuation synonymously.
The data shows that on average the referee appraisal carries a higher value for lender customer employed properties than for lender court appointed properties. This may create a potential selection bias issue. However, we performed a Probit analysis of CE choice. The regression was insignificant. Therefore, we conclude that the potential selection bias does not pose a serious problem.
The referee valuation is thus “anchored” and this can increase error rates in some cases (Diaz and Hansz 2001). However, given the magnitude of biases in this setting, a referee may serve a very useful role.
