Sadly in the US many of the companies that control large amounts of housing are all using the same software to calculate how to all raise prices as much as possible every year without having people move out. Around 2010 I moved from a studio with a shared kitchen that was $650 to a one bedroom for $900. Those studios (20m2) now start at $1,000, and the one bedrooms (50m2) start at $2,240.
