The number of housing buys in the US and Canada that are by Chinese nationals is low single digits. Chinese people, AirBnB, and boomers seem to be the boogeymen of choice for people who want to blame high housing prices on anything other than the fact that new housing supply has been retarded while demand continues to increase at a low but steady rate.
If demand grows while supply stays constant, any 7th grader could tell you the consequences, but this basic fact seems to elude our elected officials.
