How many foreign nationals own property in Vancouver? How many of those properties are unoccupied? I can't remember where I spotted reporting on those two questions, but I wouldn't be surprised if the city publishes real estate transaction data such that the number of foreign purchases can be gathered. I remember a very small portion reported.
