Two major doubts hang over any developer planning to dip into Beijing's booming property market, according to Zeng Fang, chairman of the billion-yuan, privately owned Dee Heng Group - life after the Olympics and land supply.
Although strong economic growth and development ahead of the Games points to a positive post-Olympics market in Beijing, not even a veteran like Mr Zeng can say whether there will be a crash.
Mr Zeng said he visited Sydney shortly after the 2000 Olympic Games and saw property prices take a dive.
'But I tend to believe that that was because the population of Sydney is relatively small, in which case, Beijing may follow a different path,' he said.
Beijing has also been alone in that probably no other Olympic host city has seen land disputes on the scale that it has experienced over the past few years.
Mr Zeng said the other source of uncertainty was government land provision.
