Moving into a first apartment comes with enough uncertainty without discovering that someone else has already settled into the bedroom listed under your name. Add conflicting information from the leasing agent, and a simple roommate arrangement can become complicated before everyone has even officially moved in.
One 21-year-old Reddit user signed a lease for a four-bedroom apartment with two friends and asked the leasing agent to find a fourth tenant. Months later, without any meaningful update, they discovered that the mystery roommate had already moved in and chosen room A, the bedroom specifically assigned to the poster on her lease.
When contacted, the new roommate explained that the agent had told her tenants could choose or switch rooms freely. She was also already settled and reluctant to move again. Scroll down to see why the poster is wondering whether insisting on the room listed in her lease would make her unreasonable.

Few conflicts become awkward faster than discovering that two people have been promised different versions of the same thing. The OP signed a lease assigning her to Bedroom A, while the new roommate says the leasing agent told her rooms were effectively first-come, first-served and could be rearranged among tenants.
Neither woman appears to have created that confusion. Yet because management failed to communicate clearly, they are now being pushed into fighting each other over the consequences.
The OP is reasonable for wanting to continue pursuing the room. A written lease stating “Room A” creates a much stronger expectation than an informal statement from an employee that tenants may choose among themselves.
That does not necessarily settle the legal question without knowing the jurisdiction and complete lease terms, but it does mean she is not being petty for treating the assignment seriously. The leasing company should be required to explain the discrepancy.
The new roommate’s reluctance is understandable too. After three weeks of cleaning, arranging, and personalizing the room, moving no longer feels like simply choosing another empty bedroom.
Psychologist Frank McAndrew explains that people become territorial because personal spaces help communicate identity and provide control over their environment. Bedrooms, apartments, offices, and similar spaces can quickly begin to feel psychologically “ours” once we occupy and personalize them.
Behavioral economics offers another piece of the puzzle. Research on the endowment effect shows that people tend to value something more once they feel they possess it, making surrendering it feel like a loss even when they had no strong attachment beforehand. Behavioral economist Gizem Saka, Ph.D., describes how this attachment can form surprisingly quickly.
That may explain the roommate’s resistance, but it does not mean the OP must absorb the consequences. Her offer to help move everything and deep-clean Bedroom D was actually a thoughtful attempt to reduce the inconvenience.
The more questionable part is the leasing agent’s behavior. Research summarized by the American Psychological Association shows that people react strongly to unfair procedures and inadequate explanations, sometimes even when the eventual outcome itself is acceptable. Clear, consistent processes matter because they prevent exactly this kind of resentment.
So the OP should keep pushing—but primarily through management, not through repeated arguments with the roommate. She should document the lease assignment, ask the leasing office for a written explanation, and require them to resolve the conflict they created.
The roommate may understandably hate moving. But being settled for three weeks does not automatically erase someone else’s documented claim to the room.
These are the responses from Reddit users:
These Redditors warned OP could be liable for damage to the room assigned on their lease
These commenters said the written lease should settle the dispute and the leasing office should enforce it
These users advised OP to firmly tell the roommate to vacate the assigned room rather than negotiate further
These Redditors felt the roommate deliberately claimed the better room hoping OP would eventually give in
Should the roommate move immediately, or should Kyle be the one answering every uncomfortable question first?
