A rental agreement, also known as a housing rental agreement, short-term rental agreement or insured short-term rental agreement, is a contract that defines the obligations and expectations of the relationship between a landlord and a tenant during the lease. The document can be used if a tenant is to receive the use of a room in a property, but has not transferred it to exclusive ownership and shares the common parts of the property with the owner and / or other people. In particular, the landlord should retain access to the room to be used by the tenant. It is important to have a written contract between a lessor and a tenant in order to define all the responsibilities and obligations of each party during the lease. In this way, both sides understand and agree on the terms, which can help avoid conflicts and differences of opinion in the future. .
