I remember someone somewhere way back posting links to different sites dealing with state's tenant/landlord laws. Since you are not a tenant yet, I'm not sure if this would require something different. But state laws vary to the degree to which it favors the landlord over the tenant. Here a place to get you started and hopefully find an answer:
