A resident does not need to have a lease to live in a building. The keys to the rental property belong to the owner and are returned by the tenant to the owner at the end of the lease. The tenant will not change the locks of the rented property, re-encrypt it or create double keys. In case of need for spare keys or new castles, the tenant will ask the owner for them. Share the costs of your rental by renting a unit of your apartment to a roommate. With a roommate contract form, you can legalize the terms and conditions of another person who lives with you. This Agreement, including all facilities (if any), constitutes the entire Agreement between the Parties, which supersedes all prior negotiations, agreements and obligations, whether written or oral related to this Lease. Any amendment to this Agreement must be made in writing and signed by each party.
