New York can be a very expensive place to live. It can also be a cheap place to live. 10 grand, done right, will last you a long time in New York.
My advice would be:
- If you have a car, get rid of it. Do not, under any circumstances, bring it to the city. This alone will save you a ton of grief (parking, tickets, rules about which side of the street you can park on and when and so on) and money (insurance in the city I believe is higher) and you simply don't need it;
- Get rid of your stuff. You need a suitcase of clothes, a computer and, well, that's about it. The more of the rest you can get rid of the better;
- There are decent parks of Brooklyn and Queens you can find a room for $1000/month or less. Ideally you want to find a room and not sign a lease right away. It's more flexible;
- You can live out of the city and commute in for job interviews. This will save even more money.
I live in New York and love it. New York is the kind of place where attitude matters. You have to decide to like it. If you do you'll love all the great things: the energy, the proximity, things going on, etc. If you decide to hate it you'll notice the bad things.
Good luck.
