Non-local residential property should be taxed at a significantly higher rate than owner occupied or locally owned properties. That would both solve the problem and provide much needed revenue.
2. All real estate used for income production - i.e. AirBnB for significant percentage of the year
3. An owner can declare a single piece of property their primary residence, all others are taxed as commercial property.
4. etc....
Vancouver needs to define "residents" and tax property that is not being held by non-residents.
