He was either lazy, or knew the only higher price sale he could find was not really a "comp" and shouldn't be on the grid. Which is it? A highly superior or not similar sale gets called a comp, what a joke.
if the only reason it gets put on the report is to bracket a sale price then the appraiser knows it. Some appraisers are brazen and do it as routine. Others won't do it and if their OMV falls below a SC price they stand behind their OMV
So appraisers have to make a choice-imo, some appraisers are so poorly trained or clueless they see nothing amiss about it. If an appraiser deliberately adds a not similar or superior sale for the sole purpose of price bracket to hit a value they understand what they did, but do it anyway. I never could come to grips with what is worse, doing it out of ignorance or out of intent.
