fire sale: chinese selling off hk homes, page-6

Biggest risk in Australia due to Chinese investment is in the apartment area in my opinion. I still can't fathom how all these units being built in high rises are finding tenants. As I understand it they aren't, many are not being offered for rent, so what happens to the apartments if/when the Chinese need to sell out due to a faltering Chinese economy? Over-demand of sellers and a flooding of cheap apartment rental accommodation onto the market. How are all these 2-bedroom city apartments of 60square metres worth $600K+?
