This article from the Wall Street Journal today covers the difference between real estate finance now and in the 1980s. It says that there are "stricter controls" on how funding is received and cites the restructuring of REITs as the reason. But this is only true for those REITS with good enough credit to raise money in the corporate bond market. For the remaining large quantity of developers I believe it's because of the development of CMBS and the control of debt in the hands of very few, very conservative investors. Notice that CMBS and its $6 billion market is not mentioned. It's the elephant in the room.
