Does the university offer any graduate student housing? That would probably be your cheapest option, if you think you could make that work for yourself. I moved to an expensive Northeastern city to go to grad school years ago. I moved with my long-time boyfriend at the time, so we were able to split housing expenses. I worked prn at the medical center attached to the university, mostly on weekends and worked as much time as I could get on holiday breaks and during the summer. We got the cheapest apartment we thought we could stand to live in. BF and I had two cars at home, but we only brought one with us to school and walked a lot. Fortunately, most everything we needed, or needed to do, was within walking distance, including his job, so we were able to use the car very little (I had to drive to my clinical placement and to a decent place to get groceries). He was working full-time, but I made so much more per hour as an RN that we came out about even in terms of income. I made enough $$ working to cover my living expenses, and got a couple scholarships
and took out federal student loans to cover (just) my school expenses. It was challenging, but we both made the effort to live a "starving student" lifestyle during that time rather than run up a lot of extra bills/loans (as I saw a lot of my classmates do).
Best wishes for your journey!
