I appreciate your confirmation that inspection is not required by USPAP.
Yes, by necessity, a personal inspection has been commonly conducted. For decades photos were commonly taken with a camera that used film and reports were delivered on paper. As technology changes the things that were formerly common and/or necessary also change. And I can tell you from first hand experience, because I was an appraiser when both of those changes happened, many appraisers resisted those changes as well. Heck, I remember the uproar when my firm bought forms software - the appraisers could not fathom typing their own reports.
