(Or Rev. Stat. Oregon leases are used for tenants who wish to lease land to the owner of residential or commercial real estate. The tenant must make regular payments to the landlord in exchange for the use of the rental space (usually the first of each month). Before the contract is signed, the landlord can request the tenant`s personal data to conduct a background review and determine if they can afford to pay the rent. Access to the property should only be granted if both parties have agreed and signed the lease. If the owner requests a security deposit, the transfer must be made before the start of the rental period.
