Beware of companies that charge you for a list of available rentals.
The only fee to submit an application to lease is for a credit report (no more then $30)
Also, get everything in writing. If the landlord say's they will take care of something, ask him/her to put it in writing or try and chat by email, that way you have copies of the conversations.

You also want to pay attention to the section that covers you rent after you original lease date is over. Make sure you know exactly when your lease is up and how high the rent will increase once it is over. Find out how much your month to month will increase and how they will notify you of the amount. All in all read the fine print.
So many people just sign without reading... they could avoid any misunderstandings later on, after all the written contract is what is enforceable.
