Are there still rent controlled apartments in NYC?
Of course. But the real estate lobby is slowly but surely bribing them out of existence.
I don't live in NYC (obviously) but I did read on a question and answer type site A while back that there are rent controlled apartments in a part of the Bronx called morissania ( or something like that). Apparently the place is a real shithole.
There are still loads of rent controlled units in all of the outer boroughs, not just the Bronx. But unfortunately, yeah, Morrisania is home to the poorest zip code in the United States.
