Please consult Professor Steve Levitt's, of the University of Chicago (one of my alma maters), Freakonomics: A Rogue Economist Explores the Hidden Side of Everything. He talks about and empirically proves that Real Estate Agents have no incentive to serve their client's interests for points you just made. Here is a summary:
Levitt took up a hobby: rehabbing and selling old houses in Oak Park, where he lives. This experience has led to yet another paper, about the real-estate market. It is his most Chicago-style paper yet, a romp in price theory, a sign that the university's influence on him is perhaps as strong as his influence on it. But Levitt being Levitt, it also deals with corruption.
While negotiating to buy old houses, he found that the seller's agent often encouraged him, albeit cagily, to underbid. This seemed odd: didn't the agent represent the seller's best interest? Then he thought more about the agent's role. Like many other ''experts'' (auto mechanics and stockbrokers come to mind), a real-estate agent is thought to know his field far better than a lay person. A homeowner is encouraged to trust the agent's information. So if the agent brings in a low offer and says it might just be the best the homeowner can expect, the homeowner tends to believe him. But the key, Levitt determined, lay in the fact that agents ''receive only a small share of the incremental profit when a house sells for a higher value.'' Like a stockbroker churning commissions or a bookie grabbing his vig, an agent was simply looking to make a deal, any deal. So he would push homeowners to sell too fast and too cheap.
Now if Levitt could only measure this effect. Once again, he found a clever mechanism. Using data from more than 50,000 home sales in Cook County, Ill., he compared the figures for homes owned by real-estate agents with those for homes for which they acted only as agents. The agents' homes stayed on the market about 10 days longer and sold for 2 percent more.
