based on the fundamental demand for housing and predictable economic factors", and that "a general slowing in the rate of price growth can be expected, but in many areas inventory shortages will persist and home prices are likely to continue to rise above historic norms". Following reports of rapid sales declines and price depreciation in August 2006, Lereah admitted that he expected "home prices to come down 5% nationally, more in some markets, less in others. And a few cities in Florida and California, where home prices soared to nose-bleed heights, could have 'hard landings'." National home sales and prices both fell dramatically in March 2007 — the steepest plunge since the 1989 Savings and Loan crisis. According to NAR data, sales were down 13% to 482,000 from the peak of 554,000 in March 2006, and the national median price fell nearly 6% to $217,000 from a peak of $230,200 in July 2006. John A.

Following the collapse of the subprime mortgage industry in March 2007, Senator Chris Dodd, Chairman of the Banking Committee held hearings and asked executives from the top five subprime mortgage companies to testify and explain their lending practices. Dodd said that "predatory lending" had endangered home ownership for millions of people. In addition, Democratic senators such as Senator Charles Schumer of New York were already proposing a federal government bailout of subprime borrowers in order to save homeowners from losing their residences. Causes Extent Home price appreciation has been non-uniform to such an extent that some economists, including former Fed Chairman Alan Greenspan, have argued that United States was not experiencing a nationwide housing bubble per se, but a
