Vietnam
Average rent of a luxury two-bedroom apartment: $1,800
Annual per-capita income: $2,800
The business hub of Southern Vietnam, Saigon's high-end real estate market is largely stable. In the third quarter of 2009, construction began on a dozen residential projects. Demand for those properties is robust: the Diamond Island, a luxury apartment complex, sold three-quarters of its 120 units before it opened.
