Interesting post that seems worthy of exploring further...
Your experience with lenders doesn't really sound like it matches mine. I tend to be very proactive, comprehensive and detail-oriented in my communication with lenders from the moment I first meet them, and that has served me well in minimizing certain challenges.
Over the years, I've worked with more lenders than I can count, and everything has not always gone perfectly every time. Despite a few bumps in the road that I've assigned to what I'll call my "loan process education," I've never felt any of them did an intentional "bait and switch con" on me. To the contrary, they all wanted me to get the loan and, for the most part and to the degree they could, they were up front about trying to help identify and eliminate roadblocks. I've dealt with one or two people in the lending world whose competence I questioned. I wish they'd been better at their jobs at the time, but I didn't feel like they had any malice of forethought.
With only one or two exceptions, the appraisals on my properties have either been about what I had expected them to be or a little higher. Have I just been lucky? Or maybe I've just been sufficiently conservative in my property value calculations.
I'm intrigued by your assertion that, despite the relevant Dodd-Frank regulations, the invention of the Appraisal Management Company (AMC) was just to provide an illusion of independence. Even if that's true, which I won't dispute for now, why is it ultimately a problem? Conservative lending seems like a good thing. Isn't it? If I were making a loan, I would be conservative too. Wouldn't you?
I realize there are times you need an appraisal to come back at a certain minimum value and that a lower number can be frustrating, but I'm not sure how adding more government regulations will help prevent underestimation. Appraisals are, at the end of the day, educated opinions. Unless we want to try to take the human element out of the picture altogether (i. e. eliminate the job of "an appraiser"), it will likely be easier for those of us who perform unofficial real estate valuations for our own purposes on a regular basis to adjust to the system instead of trying to make appraisers and lenders adjust to us.
