<prompt> Human: Hey everyone - Im hoping for some advice on a rent splitting situation with my roommate planning to move in together in September. We decided about 6 months ago to live together when we graduate university, and after that, her dad decided that hed be interested in buying an apartment to rent to us. He ended up buying an apartment in the last month, and the plan was that we would start renting from him in September. I was not involved in the decision to choose the apartment since I wasnt located in the city were moving to - my roommate and her dad chose it. Everything seemed great until she told me that 1 she is getting the significantly larger master bedroom with a private bathroom and 2 we will have separate contracts and pay the same amount of rent. Im really frustrated because the master bedroom is 150 square feet a large private ensuite, balcony, and large windows, while the second bedroom is 90 square feet with a small hallway in front, but has no windows actually in the room, virtually no closet, and no ensuite. While Im not completely opposed to taking the smaller room, I feel really uncomfortable paying half the rent the apartment is worth given the substantial difference in living space and amenities. My roommate and her dad seem to think this is fair because he bought the apartment, but I feel like Im in a really hard situation since I dont think its fair to pay half the rent for a much worse room. What would you recommend that I do to negotiate? EDIT: Im in Canada not in the US in a city where its not legally required for bedrooms to have 2 exits have a window I think this is crazy but for some reason they changed the law about a year ago. Ive also lived with this roommate along with 3 others for the past 4 years at university so I know we are compatible living together, but it does seem like a bad situation to rent from her dad. EDIT 2: I can totally see after reading the replies that I was looking at this the wrong way framed it badly. Really appreciate everyone who said that it doesnt matter what she pays. For everyone asking if its above market rate: yes, the rent they want me to pay is several hundred dollars above market rate for that kind of room in the area... Typical 2-bedroom apartments in the area go for 2800-3000 and the rent would likely be split at least 4555 if not more for this type of uneven rooms which makes my room worth no more than 1350. I calculated it like some posters mentioned where I take my space 50 of the common space and that implies I should be paying 40 of what the market value of the apartment is. Assistant: I would back out and rent from anyone else. You dont want to have an awkward situation where your friends dad is your landlord especially when hes already shown hes happy to take advantage of you . Also if youre not prepared to back out then you are not in a position to negotiate Human: Thats a great point. I guess I need to decide if Im prepared to back out and then if I want to use that a negotiation point. I know my prospective roommate really doesnt want to live with someone she doesnt know so it could end up being a negotiation point if I say Im out if we pay the same rent.  <response>: You also need to not make the argument about whether your Rent is the same. Thats besides the point as thats a discount from her dad to her. You need to decide if you are paying a fair market value for what youre getting.
