If you can't do the former, then the latter will not be achieved either. Sure, you might be able to free up a handful of currently underused properties with policy, but that's not going to be a significant amount. You might not like the official numbers, but that's all we've got, and you've argued in posts like
this that people's perception is less valuable than the actual data.
But just because cap rates are low, the rents paid in Vancouver are still high compared to other cities, right? And if they are not, then what's the problem?
This is the first source of data I found and I have done no fact checking, but I see little reason it would be way off:
So, regardless of the cap rates, Vancouverites still pay obscene rents, despite them also earning meager wages. You can tinker all you want, but the problem is clear, there are not enough units available to buy and/or rent.
And, as I said before, on this I totally agree. Despite all the hot air about affordability in our big cities, until (if ever) home owners have less political weight than renters, this problem will not be solved, because the population unknowingly do not want it to be solved. It's zero sum, for those without a house to be able to get cheaper accommodation, then those who currently own properties need to see the value of that property decrease.
