At least from 2012-2018 - in my circles - everyone was blaming "Chinese cash-buyers" for a lot of problems.
I think 3 things:
1) Vancouver has a MUCH higher ratio of immigrants - especially immigrants that feel comfortable enough with their long-term situation - to purchase than in LA or San Diego. The Bay area might be close.
2) Although the percentage of foreign buyers is less than 10% in Vancouver and not the actual reason for the problem - that ratio is a lot higher than in LA, San Diego, or The Bay. It's closer to 1% in CA.
3) Most importantly, Vancouver's price to rent & income (after taxes) are BAT$HIT insane compared to California.
So although it's not the reason for Vancouver's high prices - and no one should be talking about it - it's not surprising that people talk about it more in Vancouver than in LA.
Not saying it’s a bad thing, but it’s not just seething racism at play, there were major waves of immigration into the city, which drove up housing prices.
I imagine that they're all financing YIMBY organizations, whose aims would do nothing but increase the value of their holdings.
