It'll be impossible to get such data, but it's probably a huge amount, coming in different sources: - direct purchase of RE by Chinese nationals - international trade disproportionately benefiting coastal cities and major metros, attracting more people to those regions and making them richer - money channeled from China into investment funds, which in turn invest in mortgages, and collectively with other hot money, drives down mortgage rates thus making it cheaper for people to invest in RE.
