Man, I usually agree with 95% of what you say...I think you are wrong on this.
it is our job to know about why people do what they do. Appraisal 101.
I guess you have never used the survey method to support your comps? Or never contacted the re agent to ask what the feed back was on a comp or the subject property?
Just like when you make that condition adjustment, you have to explain why. Just making the adjustment is no longer good enough. Why.....same for the neighborhood.
Sure, you can have data showing there is a difference. But are we no different than an AVM? If we are to make adjustments, but not explain why....just use an AVM.
I wonder how well that would hold up in court. Why did you make that adjustment? Because the data said so? But why? Dunno, that's what the data said.
Why? Schools, amenities, airport, employment centers, public utilities, etc.
