Look on zillow and check regularly? Are you looking for near a school, or are they moving there to work?
My cousin who works on Wall Street (for high pay) has a studio apartment complete with a murphy bed. He and his wife basically live in one room with a kitchen on a wall, a bed on a wall, one closet, and a tiny bathroom. Depending upon where you live now, you might be surprised to here that it is not uncommon for roommates in big expensive cities (NY, SF, Boston) to share a bedroom because rents are so high.
Good luck in your quest!
