Ethical people who appreciate full disclosure when involved in a real estate transaction. All parties to the transaction who are fully informed have very few surprises after closing, and agents reap the reward of great referral business from previous clients.
I agree with Chuck's assessment of the U.S. market, in which the source of those massive frauds sprouted from Fannie May and Freddy Mac, the two government sponsored enterprises who, at the beckoning of a couple of congressmen, loosened lending requirements and relied heavily on up market leverage, i.e., selling of risky loan portfolios on the secondary market. When a taxi driver or a waiter could purchase an $800K home on a $$30K income, and the secondary market was giddily stupid by thinking the up market would last forever, the bubble was bound to burst.
Americans now know that buying a house is not one of their civil rights. Some people should never own a home, and now the U.S. market is attempting to recover from that.
