<human>: I currently live in an apartment complex in a two-room unit. I'm moving to a different two-room unit with a friend within the same complex, but the building has changed rates for any "new" tenants. If I were to stay in my current room, my rate would not change at all, but by switching rooms, my rent increases $55. Also, if I resign the same lease in the same room, I would be paying less than my neighbor who has the exact same unit as me (provided he is a "new" tenant). Wouldn't charging more rent to a certain group (new tenants) be a form of discrimination against new renters? This can't be legal, right?

Can you provide a brief overview of the text?
<bot>: Apartment complex offers different rental rates for the same room configurations based on no qualifications other than prior-rental status with the building. Is this discrimination?
