Flacco, I'd still counter that the "guidelines" that are set forth, many RES (I used to be one of them) appraisers interpreted them as "gospel" or "USPAP"
The whole 15% net/25% gross or the comps being within a certain time frame (i.e. 90-180 days etc) ...
What I am saying is that too many RES appraisers take that to mean they are NOT allowed to use anything outside those "guidelines"
I get that question often enough from borrowers/homeowners or agents (even seasoned agents) of "Can you exceed 1 mile/6 months, etc"
My answer is generally an emphatic YES!!!!
My job, as an appraiser, is to find the most similar/comparable sales available. If that includes older/dated sales or sales "outside" a mile ... so be it
Generally I start my search criteria within the "guidelines" (90-180 days/within 0.5-1.0 miles - I'm in an urban/suburban area) ... but when I need to exceed that criteria, I have no problem doing it!
It just means I have more explaining to do as to WHY I exceeded the "guidelines"
And THAT's what I think a lot of appraisers fail to do, IMO. I think many clients/lenders (and underwriters) are left wondering WHY an appraiser may have "exceeded" the guidelines
