Question for pondering - What do you think would be the net effect on credibility if the following changes were made in "FannieWorld" ? (1) eliminate the requirement to view comparables from the street, BUT (2) add a requirement for a report to contain actual support for any adjustment exceeding $x or y%. Just curious as to thoughts on this.
I don't see what one has to do with another. Imo, whether or not to drive a comp should be the appraiser's choice as part of their SOW ( as is looking at overhead and aerial maps and MLS photos of the comp, all of which often impart more information than the drive by). If an appraiser feels they need to drive by every single comp, (or loves driving around), then they should do so. If appraiser feels confident in MLS photos, overhead maps and knows area and does not need to drive teh comps that should be tehir choice, or they may feel the need to drive one comp and not the rest. That to me would be ideal but I am not in charge jmo.
As far as showing support for adjsutments over X%, that should also be up to the appraiser what kind of support, what they need to "show" , what can be in work file etc. When someone does our tax return, do we ask for sheets of their scribbling or print outs of how their calculator or computer did the math to "Support" a deduction? They either know the tax code or they don't, and if they don't, then don't hire them. Same for appraisers. If a client feels confident appraiser is qualified and knows area, why the show and tell of how they did things? In my experience having done over the years several hundred field reviews, the big problem in most appraisals is not the adjustments, it is comp selection. With good comp selection, the show and tell and support of adjustments is right there on the grid, the comps after adjustments should converge to a more narrow range ( depending of course on price point and how unique the property is). Properly applied adjsutments create that convergence so the proof, the support, is right there to see. Larger market derived adjustments such as time adjustments from additional data is easy to show or indicate.
If poor comp choices are made, does not matter how well supported the adjustments are, the results /value will be misleading or faulty.
