<prompt> Human: So this fall I will be attending university and getting a mini home with two friends and potentially another roommate. My friend has an SO that will be staying in her room, but not paying any rent, and the rent was going to be 5050 if there was just the 3 of us.I have had many friends tell me this isnt fair and I should not be paying 50, but I have no experience in renting so I have no idea. What do you guys think?My roommate did mention that shed be willing to not go 5050 if I felt the rent was too high, but idk how solid that offer is. Edit: I appreciated all the suggestions! I talked to my roommate about splitting utilities 3 ways and keeping rent 5050. She was completely fine with it, and said she would pay 23 her and her SOs cut. Thanks everyone!Assistant: If she lives in the house, she pays rent. Only other option is her SO pays her portion. She doesnt get a free ride just because she is a girl.Edit: read it wrong but same principle applies Human: So have it split 3 ways and my friend pays 23s because her SO doesnt work?Assistant: Splitting it three ways doesnt automatically imply in thirds. They are sharing one bedroom...that should come into the equation somewhere.Human: Right right makes sense thank you!  <response>: But utilities should be divided evenly in thirds. Also establish a part of the fridge to be unclaimed. Put food that you dont care if your friends or roommates eat there, usually food thats going to spoil soon. That way they dont eat whats yours. assuming they are decent people
