I live in California, which measures about 740 x 220 miles and has something like 12% of the nation's population. I have known few appraisers with an exceptionally broad area of operations but most people seem to max out at maybe 100 or 150 miles from their doorstep. So in my state an arbitrary 30-mile limit would put a very real damper on what most appraisers here are *capable* of doing during the normal course of business.
Shoot, a few of the property types I appraise sometimes have comps that cross county lines, and not by a little.
So the applicability of the question isn't strictly limited to the hotbutton issues some of you are having with the big AMCs. These are questions that come into play on the more local level as well.
How many neighborhoods, outlying communities and even counties that are nominally in what you consider to be your AO are there that you haven't worked in over the last 3 years? Is your lack of recent exposure to those individual market segments a deficiency in competency that rises to the point of being reportable under the requirements of the COMPETENCY RULE?
