Does your school have a Facebook group for housing? Can you post there with a description of yourself, what you’re looking for in terms of housing next year, and see if anyone bites?

If neither applies to you, can you try posting on Craigslist?
By the way, I live with two males and one female. Never been an issue since none of us have to share a room.
