HCMC real estate market spirals downward

Hanoi offered the highest grade A office rental yield in the world last year -- 8.57 percent, a Savills report said.

Investors buy a high percentage of high-end residence purchases in Vietnam, while occupiers take most of the low-end ones.

Foreign investors currently own majority stakes in about 50 percent of high-end office buildings in downtown Saigon.

There is massive interest among foreign investors at the moment.
