I was wondering this too, I know plenty of people who live alone in Manhattan and don't pay anywhere near $5k. Some renewed recently even but I don't know who had stabilization and who didn't.
Where did you see the $4k number? This looks like condo and co-op numbers mostly?
It is highlighted in the reference I gave (which I found in a NY Times article). Look for “view report” after “The median rent in Manhattan reached the $4,000 threshold for the first time as lease signings continue to rise.”
