Timing the bubble “burst”
Thousands of apprehensive sellers and buyers have been playing this game since the late 1990s, trying to time their sale to either beat the “pop” and gain optimal profits, or to swoop in and pluck up cheap property after a burst. In almost all sections of the country, the bubble remains “intact.” For the most part, real estate bubbles don’t pop, they just slowly deflate and the market levels off then surges again in the near future. Always take the approach that real estate is a long-term investment.
