Moving out..question about last month rent
My lease is up the end of February and I am not renewing. When I moved into my apartment 11 years ago, I needed to pay last month's rent and a month security deposit (1st month was free). At the time, my rent was $595/month. Now my rent is $875/month. Do I need to pay the difference between what is was and what it is now when I leave in Feb?
