NYC has negligible vacancy rates and airbnbs are already illegal. Sounds like a supply problem. The supply problem gets clearer when you realize how quickly the jersey side has grown. It's because NYC has no supply.
I have no proof for this, but lots of influencer types, nepo babies and people with remote jobs moved to NY during covid and didn't leave. NY Metro population never saw a covid dip, has been steadily growing and RTO mandates are probably causing suburbanites to consider moving back into the city. We are seeing price increases from a repressed real estate market that's finally making bank from the supply crunch.
Compare NYC metro area to SF metro area. NYC saw smaller covid drop, larger subsequent pct growth and a much much larger absolute growth rate. Rent control won't fix anything. They need to start approving market-rate housing at a mad rate. Austin is a great reference.
