This is false. There are lots of small, old crappy houses in Vancouver. It's just that they cost a ridiculously large amount of money.

Here's a pretty typical example: https://www.realtor.ca/Residential/Single-Family/17409318/55...

Before you ask, no that's not even in a really desirable part of Vancouver.

That will cost you another million. See this as an example: https://www.realtor.ca/Residential/Single-Family/17850427/31...

No you are very incorrect. 81% of the land area of the City of Vancouver is zoned for detached homes and most of these are simple, cheap post war houses or cheap 60s era "Vancouver Specials."

The houses in Vancouver are so crappy someone even made a joke quiz about it, in 2010, when the prices were a lot lower: http://www.crackshackormansion.com/
