This isn't really true though. Housing is expensive everywhere, even in unpopular cities, even in cities losing population. (Except for a few specific cities), housing is not scarce, we just pretend it is because we pretend all these fake financial transactions count as valid 'demand'.
> we're focusing on foreign buyers in 2022. And blind-bidding in 2021. And investors in 2019. And money-laundering in 2018. And Chinese money in 2017. All of these things should be addressed, but every one of them has provided political cover for the real reason that housing is so expensive in popular cities, which is scarcity
And why is housing "scarce"? Because we waste housing on fake buyers (every single thing you just mentioned). That's why it's all in focus so much.
My midwestern city has built 2x to 3x more housing units than it's received in new residents, for almost 15 years straight now, and housing still goes up 15% each year like clockwork. You can outbuild new resident growth (many places already do), but you can never outbuild investor demand while housing is federally forced to appreciate like this.
I'm so sick of people bullsh*tting that 'zoning' and 'nimbys' are why housing is expensive, when we have dozens of major cities with no meaningful zoning restrictions, no 'nimbys', and no restrictions on growth or construction of any kind -- and even in these cities, housing is shit and expensive.
