$3,000 per month for one person in Washington, D.C.

I have a $2300 per month after tax Roth IRA and am thinking about moving to Washington, D.C. for work. If I live alone in a 1-bedroom for $1800 per month, that leaves me $500 per month for everything else (health insurance, food, transportation, etc). Assume that I will not be paying for anything related to retirement savings.<br><br>What are my best options for these things? I assume I will only have a cell phone (no home internet, no traditional television, etc).<br><br>I can pay cash for a beater car, so it will not have a car payment or be fancy, but I'm sure it will come with other expenses.<br><br>I'm willing to cook and eat rice, beans, pasta, etc. but I will want to travel occasionally, if even to a park or hiking in the mountains (so the car will come in handy).<br><br>What health insurance options will be available to me? Are there ways to save money on these things?<br><br>If, in reality, $2300 per month is not enough to live alone in Washington, D.C. (though I believe it is), then how much would I need to live comfortably in another city, if the salary is adjusted for cost of living?<br><br>Tl;DR: How to live off of $2300 per month in Washington, D.C.
