The deposit amount. What utilities you are expected to pay. How many day's notice you must give before moving out. Other conditions you and the landlord agree to follow. Your lease is a legal, binding contract-make sure you read it carefully before signing it.
Few landlords rent by the month.
Most require you to stay for six months, one year, or for the school term. Often the landlord will require you to pay the first and last month's rent in advance. If you move out before the date agreed upon in the lease, you may lose the money you paid for the last month, or you may be required to pay rent for the entire time of the lease, even though you won't be living there. Before subleasing your apartment, check your lease contract to see if you are allowed to do so. In such a case, you can seek help from the student legal service or attorney at your school or from the Community Legal Aid Society.
