No, this is not a good comparison. The price rental calculators tend to show renting is the correct option in Vancouver.
If it's paid off, it's perhaps fine. But many people owe mortgages on those houses. They will be in for a world of hurt if house prices drop. I.e. The exact scenario we are discussing here.
Rental can be a good move, but as a rational decision it should include the possibility of future price increases. Buying does this, you have covered yourself against all future increases, and accepted the risk of all future decreases. That is smart if you are committed to a location for non rational reasons like your kids are happy at school or you like it.
Agree that holding mortgages that expose you to negative equity risk is a big gamble. Like stocks (real stocks, not options or non-listed equity) it's actually a good gamble if you will be able to cover a 5 year price dip. If you are likely to have to do a distressed sale at a stress point you are setting up a big loss - smart to take the risk if you are in your early 20's (the upside is great, you'll be ok if you bust) but dumb if you are >45.
