I own Prime real estate in Shanghai and Hangzhou and I can say from my experience that while prices are astronomical, many people are waiting for a drop. If I tried to sell at current market prices quoted for me, I would get no buyers. Its actually been like that since last year. I own apartments as well as commercial offices in Shanghai. It seems that while people are moving into cities at a faster rate, they are not financially able to afford it yet. I had an offer recently on one of the apartments I am trying to rent, by 7 families combining savings to pay for the rent alone.
Although if I accepted a price even 2% below fair market value, I would get a ton of buyers..
That said I still believe in the long term prices will move up...
