It sounds like you may be younger or not have much experience with Real Estate in the USA? I have owned property for the last 50 years. What I found was location, location, location was the determining factor for appreciation. In 99% of the economic downturn's since 1970 prices on real property didn't fall much at all. Price could stagnate for periods but you didn't see major price drops. So if you are betting on large property discounts you're going to need a war in the USA.
The only time I saw prices drop significantly was after Lehman filed for bankruptcy Sept 15, 2008. Two weeks later on Sept 25, 2008 the FDIC swooped in and took over Washington Mutual making their shareholders paper worthless. The FDIC gave WAMU which was worth 46 billion at the end of 2006 to JP Morgan for a mere 1.9 billion. The acquisition ultimately allowed JPMorgan to expand its consumer banking footprint significantly, making it the largest U.S. depository institution with over
$900 billion in deposits and more than
5,400 branches. While the immediate financial impact included costs and markdowns, the long-term strategic benefits and expansion of market presence were viewed as creating substantial value for JPMorgan Chase.
Between Sept 2008 and Sept 2009 many homes were valued lower than their mortgage. We hadn't seen anything like this since the Great Depression. Everyone saw houses as a stable investment. Those that ignored the noise and bought homes during that time did very well. Many of those that participated in the feast were publicly traded companies. All the homes that were lost by owners who sold during that period are now in strong financial hands and the pendulum has completely reversed. If you expect the Real Estate market to fall significantly again, that's a long shot. About the best you can expect is slower price increases. The government learned a lesson on Lehman. Don't expect that again soon.
