I told a realtor once that appraisers do not appraise a home, data does. I was trying to respond to their over-hyped level of concern about where the appraiser lives or works and the realtors’ hope that the appraiser will have some sort of intimate knowledge about the subject property’s market area. Appraisers don’t need to live near the subject property to do their job well.
If the data exists, i.e. recent settled sales that make for appropriate comparables for an appraisal, then the appraisal should turn out fine. In other words, it is not about the appraiser, it is about the data!
