Where you live and who you live with over the next 12 months can have a profound effect on you positively or negatively. In this type of situation haste does make waste. Do not sign anything, or fill out any applications until you are certain you have identified the place you want to rent. Some applications will automatically legally bind you to the lease. Don't sign anything unless you can afford to pay for it.

This is a business arrangement between you and the landlord. Get everything in writing and document conversations so there are no misunderstandings by you or the landlord later on during the lease. Know what you are signing. There are two types of leases commonly used in this area. Joint and several and individual leases.
