Landlord did not disclose auto renewal rate

I’m a renter, and my lease is ending on 10/31/2010.  I called my property manager because I’ve not yet received any disclosure about new rates for the new lease nor month-to-month rates if my lease automatically renews.  So I called my property manager to confirm that my rent was staying the same.  But my property manager told me that my rent would be increasing, which was not acceptable to me.  I gave notice that I would be leaving the property on the last day of my lease.  The property manager told me that I have 60 days notice and that I had to stay until 11/30/2010.  But she told me that I would have to pay a month-to-month rate for November of 1200 dollars (I only pay 770 under my current lease).  I checked my lease and it states that I have to give a 60 day move out notice and that if my lease auto renews, I have to pay 100 dollars over the market rate.  I was never sent any information about renewing nor about how much this was going to cost me if i missed the 60 day notice period.  Is this legal?  They market the apartments for 745 according to the property’s website.  Can they really charge me 1200 for November?  Please help. I’m a single mom, and I just don’t know where I’ll come up with the 430 dollar difference.

Thanks in advance!
