Okay Mr Stubborn, I will try to explain it again - my viewpoint just as your perception is your viewpoint.
For a Review and for a Desktop....
The appraiser has not physically inspected the subject in its entirety....
Review - The review appraiser exterior inspects subject for field review. Desktop, no exterior inspection done
Review - The subject was fully inspected interior and ext by the origination appraiser, with their measurements, photos, sources, and comments in a report. That forms a highly reliable and comprehensive document of property characteristics, in addition to other sources..
Desktop - It was not inspected by an appraiser , the data has to come from various sources, some can be reliable, others not.
I do verify or check sources and info on the appraisal in a review as well, but the starting point of information is far more comprehensive and direct.
In order for me to complete the Desktop I had the homeowner (I'm selecting a refi and/or FSBO for my examples because these assignments did not include anyone in the real estate mortgage industry)....
I would give the homeowner a list of items that I needed them to supply (and if necessary I would email them examples of what I wanted)....
1) Photos of the 4 corners of the house and street scene photos from both directions....
2) Interior and exterior photos; I instructed them to include flooring, cabinets, counter tops, appliances, inside of the shower, electrical panel, mechanical systems, attic access, air conditioning compressor, heating vents, decks, porches, etc. I required them to provide me with any and all photos that I would have taken and typically most of their photos came out better quality than my low end camera....
3) I even had them supply photos of the stairways so I was sure of the railings; I even wrote a couple of reports "subject to" repairs....
4) List of updates/remodel/etc.
5) Water source, heating fuel, etc....
If they didn't supply me with sufficient photos or information I asked for more and if I had to wait for the information so be it....
In some instances I even emailed them a copy of the 1004 form so they had a better understanding of what I wanted/needed....
From the photos of the 4 corners of the house I could determine if the assessor sketch was credible....
For me the information I received from the homeowner and the information I found on assessor online and if available MLS listing sheet....
I felt comfortable completing the Desktop....
