The reason for the massive empty inventory glut: to keep supply low and prices artificially elevated by taking out as much inventory off the market as possible. This, however, works both ways, and while it helps boost prices on the way up as the economy grow and speculators flood the housing market with easy money, the moment the trend flips the spike in supply as empty units are offloaded will lead to a panic liquidation of homes, resulting in what may be the biggest housing market crash ever observed, and putting the US home bubble of 2006 to shame.
