Sam Zell the master real estate investor has built a fortune on the cycles that shape his industry. These days he believes the current turmoil in financial markets is more an emotional reaction to yet another period of excess rather than a true credit collapse. In a talk at Wharton moderated by real estate professor Peter Linneman the Chicago-based investor said markets currently are spooked by problems with U.S. subprime lending. However they still have capital to deploy unlike other real estate downturns. ”We’re not really in a ’credit crunch.’ I think what we are in is a ’confidence crunch ’” Zell told his audience.
