Drivel. Targeted at a readership that is looking to blame anybody but the person standing in the mirror looking back.
Borrowers are to blame unless their broker defrauded them in their loan. Otherwise, the appraiser, did THEIR bidding. The Agent, showed them a way to do what THEY wanted to do. The lender, gave THEM the rope. And frankly in 99.9% of the cases, the broker, gave THEM exactly what they wanted which was a $450 payment for every $150,000 borrowed.
