If you can read a bit of history of real estate crashes, you will not want to buy a house or a condo or a town house in China. Check 1989/1990 Japan, 1997/1998 Hong Kong, and 2007/2008 US real estate market crashes. Why do people think that China will be different? Don't ask me when because I don't know when. If I know, I will never tell you.
Anyone has ever played the musical chair game as a kid? The music is still playing in China's real estate market. You just hope that you still have a chair when the music stops.
