Just to put this name calling at an end you're both wrong.  There is a stamp tax on new home purchases in Hong Kong.  It's aimed at anyone without a Permanent Residence Permit. Mainland Chinese need a Permit to be a resident of Hong Kong.  How's that for autonomy.  Most foreigners (ex-pats) rent in Hong Kong.  Mainland Chinese buy there to get their money out of mainland China.  the Tax is aimed at the Chinese not "foreigners".
