I hear that Vancouver looks well-built, with lots of huge buildings, but come evening, and a whole lot of the windows in those high-rises remain stubbornly dark.
In other words, I can’t afford to couch-surf until all the foreign capital has been exhausted buying luxury condos. I need housing right now.
Besides restrictions on supply so that it doesn’t match demand, I think the problem here is the whole idea of your house as your major investment. It seemed nice to the earlier generations, who could buy a house with 1 year of earnings and sell it for 10 years of earnings, and they in turn could sell it for 40 years of earnings, but this pyramid scheme eventually has to collapse. When only the bank can own a house, then housing prices have to go down, and the poor people who put all their investment into home equity will be the ones who suffer from losing their money.
My worry is that this investment is "flight-y" (they are not actually residents) if we double up supply and this investment leaves, SF becomes a Detroit that looks like Manhattan?
P.S: Obviously, increasing supply to meet actual renters'/new residents' demand is a no-brainer.
Other cities are not such a sure investment, a spike in supply could destroy your capital overnight.
