A few things you might want to keep in mind …
Big house, no cash. No one forced you to buy more shelter than you need. You did it in the hope of a near-term flip to some other sucker at a higher price, and ... there is no possibility that you may be that sucker.
Foreign investment. Canadian real estate is a very good deal versus global comparatives, and bought primarily to hedge against adverse change. Look forward 30 years - and to most folk, it is pretty hard to see why Vancouver would not trend towards what Hong Kong used to look like prior to the hand-over. Foreign buyers are simply being prudent, and astute.
Negative yield. In today’s world, a high net worth person, depositing CHF into a Swiss Bank for safekeeping - has to pay the bank around 0.25-0.50% to take the money. Or, they could simply buy an A list condo in Vancouver for cash - and pay a property manager to keep it rented, as an alternative store of value. Rent the condo for 3-4 months/year to cover taxes and condo fees, and flip it again for a gain as/when you need the money.
