I haven't read the entire thread, so not sure if anyone brought this up, but it seems like the lenders will choose between a $600-$800 full appraisal by a professional with little inconvenience to their customer, or make their customer walk around the house with their phone doing video and pictures, perhaps measuring, providing a sketch and noting all materials throughout to save a few hundred dollars.
Seems to me, the better lenders/clients will choose the "full service" approach to just get the damn thing done. Or they may sample the desktops and realize they're more trouble than they're worth. The companies that farm the appraisal process off to scumbag AMC's will love the desktop and try to suck every dollar off of it. Let's see how this plays out.
