You sound like your heart really wants to go to NYU and experience something new. Talk to your family and friends. On cc it always comes down to a conversation about the price difference, choosing a college can be so much more than this. Perhaps this is the only time you can get out and experience the east coast, maybe you will get “stuck” in Washington if you stay. NYU is right in front of you, there is no guarantee such an option/location will be there for grad school. If the 10k isn’t a big deal and NYU is a dream of yours to attend, then go. You will grow more going to somewhere totally knew than somewhere right down the street from where you have always been. College is a great time to live a different life than you have always known, if that is what you want to do. Good luck.
