Landlords are allowed to raise the rent once the lease has expired. If you decide to stay in the same apartment next year, you should read your new lease carefully and make sure the rates haven’t gone up. If they have, see if you can negotiate with your landlord. If you are renting a month-to-month apartment, then rent increases are more likely to occur. In this case, landlords can raise the rent every month if they wish. But it’s important to have your landlord give you a 30 day notice before the rent is officially raised. This will give you time to find a new place if you cannot afford the new rent price.
