Age of the Comparable Sales
Comparable sales that have closed within the last 12 months should be used in the appraisal;
however, the best and most appropriate comparable sales may not always be the most recent sales. For example, it may be appropriate for the appraiser to use a nine month old sale with a time adjustment rather than a one month old sale that requires multiple adjustments. An older sale may be more appropriate in situations when market conditions have affected the availability of recent sales, and the changing market conditions causing their use must be explained in the report.
Additionally, older comparable sales that are the best indicator of value for the subject property can be used if appropriate. For example, if the subject property is located in a rural area that has minimal sales activity, the appraiser may not be able to locate three truly comparable sales that sold in the last 12 months. In this case, the appraiser may use older comparable sales
if they explain why they are being used.
