Data for Year-to-Year, Room-by-Room Leases?

[Sarah Klein]

Hi BiggerPockets ATX. I know there's data out there regarding property prices, and there's data out there about the short-term rental market a la AirBnB, but do you know where I can find data on year-to-year leases for rooms? I'm asking because I am looking to buy a house where I will live and get roommates who will also be my "tenants". I am evaluating several areas in Austin, but I would like to look at data to help me evaluate which of these areas are surest bets for the types of year-to-year, room-by-room renters I'm looking for. Thanks for your help!
