It's eye wateringly expensive because the mortgages is paying off mortgages for buying skyscrapers in downtown Manhattan in the 90s, despite have pretty crappy dorms and student facilities and they've been pushing BS cow master degrees that are in the $140-170k range for 2 years while diluting traditionally strong like Stern. And the exit opportunities aren't that impressive unless you attended Stern undergrad.
I've had plenty of friends attend there for grad and undergrad, and I also had the choice to attend for undergrad years ago, but decided against for the reasons above.
You'd be better off attending a regional program that is specialized in your disciple than NYU.
