Khalid, I see you retracted your original statement but let me tell you as a renter where I am coming from. I am not trying to screw over anybody. If I asked a broker to go find me an apartment because I did not have the time nor the desire or patience to see a lot of apartments, then I would have no problem paying a broker fee. However, if I do all the work and go to buildings myself, why should I have to pay thousands of dollars for opening the door. Having said that, this situation is a little different. The only reason that I signed the agreement, was because I was 100% sure I would not take the apartment because it was not nice enough to take with the broker fee. Without the broker fee, it is much cheaper, and therefore affordable.
With that being said, if there is no "OP" then you are pretty screwed. Stalk that management and watch for a new listing to hit in the same building when your 90 days is up.
Best of luck!
