<prompt> Human: My son is considering quantitative analysis as a possible career. He already will have a computer science math double major when he completes college. However with that choice of career, he would almost have to live in New York City. There are a few other locations but not many. So I will limit this question to living in New York. I see that New York City has an income tax that is in addition to the New York State tax. He will be filing as single with no dependents. So I calculate between Social Security, State tax, city tax and federal tax if I did the math right on an income of 150,000 a year. He will pay around 60,000 a year in taxes. Realistically how much does it cost to live in the city? He will not drive to work so will need some form of transportation, he will need to live near where the investment firms are to get to work, so how much will those apartments be. Ive seen things online that a decent 2 bedroom will run you 3000-5000 a month. If thats the case that 150,000 a year job after taxes and rent has turned into 30000 a year.. Are my assumptions accurate? We live in a 3 bedroom house that is 2000 square foot now and the mortgage is only 650. So i know the locations are completed different, but I am trying to get a sense of what life in New York is actually like.  <response>: Why are you asking these questions? Shouldnt he be asking...In general, NYC is pretty expensive except for public transportation. I suggest an outer borough not Manhattan andor roommates. Are you assumptions accurate? Probably not. It seems youre considering them from your POV this is a decent 2 bedroom and not your son. This is why I asked why are you asking these questions, shouldnt he?
