Living in Chicago is expensive compared to any NC. city. What you can do with a $1200 rent depends upon where you live. If you want a condo view of the lake you will pay dearly for it. And you have no idea where the school might be. I believe Chicago is around 65 square miles and Cook County is around 900. If you're careless you can wrap yourself in a year rental agreement that is 2 hours by train from the school Living in Chicago is more than wanting to live in a specific area unless your income is unlimited.

At this point in time the advantage is you can get a short term lease of 6 months or less = which gives you plenty of time to find the perfect apartment. The SAMPLE apartments include a video and prices for each unit. It will give you a rough idea of what you can expect for your rent budget.
I suggest you sit on this forum until you move and ask questions about parking and transportation and taxes and everything else you want to know including the best areas to spend your rent money and areas to avoid. If you do you wont have any unpleasant surprises.
