Double Bubble: How counterfeit buyer agents inflated the housing bubble

Yesterday we blogged about the "Mortgage Meltdown" and record number of foreclosures, challenging the media and regulators to investigate how counterfeit buyer agents (a.k.a. double agents) helped inflate the housing bubble.  If they do, here's the kind of "glaring" case study they may find:

My so-called buyer's agent (who promptly switched roles at contract signing without explanation), initially advised me to bid $750,000 for my house of choice, which was listed at $699,900. When I told her that such an offer was beyond my price range, she was quite adamant that I not offer anything under the list price. When I finally backed out the deal because of her bait and switch scam, I later heard that the house in question sold shortly afterwards for $682,000--in other words, nearly $70,000 less than the bid suggested by my so-called buyer agent.

This type of price inflation (caused by seller's agents masquerading as buyer's representatives) must have a very distorting impact on housing costs.  The economic fallout is enormous: ordinary citizens are forced to move out farther in search of decent, affordable places to live, which  leads to a host of problems connected with traffic congrestion, suburban sprawl, etc.

As I perceive it, the real estate cartel's use of dual agency [a.k.a. "designated agency"], which works to the detriment of the average consumer while enriching dishonest agents through the practice of double-dipping, contributes significantly to the manifold problems we see in the residential housing market and therefore should be fully exposed.

The homebuyer above concluded, "Isn't there any investigative team or media personage with the courage and tenacity to shed light on this problem?"  We'd like to ask how homebuyer and sellers who have been victims of dual agency, designated agency, or faulty agency disclosure can use social networking tools, like blogs, wikis, and interactive mapping, to expose the problem and prevent other consumers from being harmed?  Does anyone know if such an organizing effort is already underway, or have ideas about how to get one started?
