A lot of students live in places run by Southern Management, like Redwood or Marlbro, the Sailcloth factory, these places are nice (relatively safe) and within walking distance but rent alone runs ~800 for a single or $1200-1500 for a double. You can find a roomate at the website listed above. There are also a lot of students that choose to live in townhouses in a place called Ridgely's Delight, you should be able to find a place there with several roomates for ~$250-400 a month but just be prepared to live in a semi-unsafe area (some students have been mugged in those neighborhood, and a lot of students who park their car there get their car broken into). If you live anywhere further then walking distance, you will have to factor in the cost of parking (3.50 per day) into your budget so that is another consideration. A couple other places you might want to look into would be Charles Towers, townhouses in Catonsville by UMBC, Fells Point, or you can call the housing office and see if there are any on-campus openings but it's already getting pretty late for on-campus places.
Congrats on getting into Maryland, I just had my last day of classes of second year today and I can assure that the first two years are very well done at my school.
