Buying a house or condo?

Any type of economic bubble is difficult to identify except in hindsight, after the crash, although many economic and cultural factors have led several economists to argue that a housing bubble exists in the U.S. The Economist magazine said that "the worldwide rise in house prices is the biggest bubble in history," so any explanation must consider global causes as well as those specific to the United States. Former Federal Reserve Chairman Alan Greenspan said in mid-2005 that "at a minimum, there's a little 'froth' (in the U.S. housing market) … it's hard not to see that there are a lot of local bubbles." President Bush said of the U.S. housing boom in early 2006 "If houses get too expensive, people will stop buying them … Economies should cycle."
