Seattle has a similar problem where we do have a large number of new units going up, but some places are still seeing upwards 50% vacancy after 3 years... because the new units aren't aligned with market demand. I'm talking luxury apartments downtown when the growing demographic is frugal-minded mid-20s/30s interested in neighborhoods 10-20 minute away from downtown. Even constructions in the right neighborhood end up being a net loss of desirable units when the rent is sky high.
