<prompt> Human: So, I live with my girlfriend and her friends. We share a bedroom and pay 600 a month.We just heard that one of our housemates the landlord wants to increase our rent for the room from 600 to 900.We are on a month to month basis, and basically just moved in, no paperwork or anything.Is there any kind of limit to how much my rent can be increased?  <response>: Maybe they want you to move out, either way its a red flag.
