The financial part of the Roommate Agreement is for many, the most important portion of the agreement. In this section, rent and security deposit obligations are covered as well as other bills such as utilities, internet and insurance. Moreover, the lease agreement does not decide the behavior of the roommates towards each other. Since the behavior of the tenants does not violate the law, roommates are free to do anything. In addition to that, it is likely that your roommate can leave the apartment and never return, leaving you to pay the rent. Imagine coming home after an exhausting day and finding the bathroom in complete chaos — you’d be furious, right? What if you’re getting pressured by the landlord to pay your rent, and you’re still waiting for your roommate to put up their half? Imagine your roommate walking in with their friend for a night stay and that overnight stay turns them into a permanent guest at your apartment. They might start sharing your things, space and other utilities. Room rental agreement is also used interchangeably with the term Sublease Agreement, as it incorporates elements and terms of the original lease agreement, and serves as a detailed and comprehensive guide for tenant responsibilities and rights.
