A rental lease contract is a legal contract used to lease a rental property. A rental lease contract may be used to lease both commercial and residential properties, though specific contracts vary due to many factors, such as the type of property leased and even the state in which it is leased in. Generally, a rental lease contract outlines the specific terms of a lease and details each party's rights and responsibilities under the lease. A contract will always specify the rental price and how and when a tenant should pay rent on the property; a lease contract may also include more specific provisions such as rules regarding parking, smoking, landscaping, and animals on the premises. Once a rental lease contract is signed, both the landlord and all tenants are legally obligated to uphold the terms of the lease. Violation of rental lease terms or terminating a rental lease early can result in legal action and/or monetary penalties.
