Lots of building is a symptom of rising prices that also helps reduce the price increases. Places with rising prices will generally also see increasing density, but if they increased density faster the prices would not increase as much or even decrease. It’s hard to come up with a counterfactual. My hometown, DC, is very popular right now and is also building quite a bit of housing and rents aren’t accelerating like they are in similar places like Boston.
