I think they still need appraisals and appraisers to feed their own data bank, and as some measure of prudence, but they took on the task of "modernizing the appraisal process mean " to "screwing up the appraisal process"
They used to go overboard on requirements and appraiser must inspect or supervise, now they are reversing decades of their own policy with a yahoo let's abandon as much as possible our role as prudent safe keeper and be like UBER/Amazon as if they are selling click purchase sneakers.
The fact they are wiling to use RE agents/others who took a one hour training seminar to inspect shows contempt for the investors who will buy the loans and the taxpayers who back them - the long term soundness of the loan collateral is being swept aside for short term front end speed to close fast (which benefits some lenders and not others , they don't all compete on speed, some on service and local reputation)
