So what happens when they get it wrong and there is another housing crash due to these inept valuations?
I will agree with SC......in response to your "Q" - well they got it wrong after 2008, and by that, IMO they just threw $$$$$$$ at it, and the Lending/Stakeholder community thought it was just fine.
Fast forward, if they can get rid of the appraisers (pre-existing, cause they're Fed. Certified) they have a full tilt boogie (control of the housing & lending market) and No one as a check & balance system. They want Total Control, and Congress and others are enabling them. Pssst, they will eventually just pass a Bill to do what they want, oh and that's in th e public interest
