I fail to see how your comments address the concept that I posted about - the expectation of appraisers to perform objectively.
Since you brought up the term "average," I would say that is an excellent example of a word that is used very differently by different people. Suppose the subject property is one where maintenance has been neglected. The paint is peeling. The roof is near the end of its life. etc. If the majority of nearby homes are in similar condition, is the condition of the subject property "average" (as compared to the homes in the immediate area), or is the condition "fair" or "poor" (as compared to the whole housing stock)? I think we know appraisers in both camps. I am not sure that was the best example for you to use.
Also, for lenders appraisal reports are risk management tools (its not just about the value), and one of the risks is litigation risk related to the content in the appraisal report. You may have seen an article or two about such litigation over the past few years. Even if one thinks the litigation is frivolous, it is in a lender's (and appraiser's) best interest to avoid it. Using objective language, rather than subjective language, is not only consistent with the very definition of "appraiser," it reduces, to some degree, the litigation risk for all concerned (including the appraiser).
