Real Estate is one of the older investment games in town - It is what I am basing my retirement on. I wonder how this will impact disclosure rules versus sales advertising? Existing model to use, or adopt another industry's? Will this cause fears of LIBOR-style manipulation? This will be interesting to watch... edit: p.s. Maybe another chance to make a Carfax-like system for homes? In the US market, I find there is not a lot of opacity, especially when one gets into larger/commercial deals.
