An Illinois residential lease agreement allows a tenant to rent property from a landlord in exchange for monthly rent and other consideration. The lease details also include utilities, length of tenancy, security deposit, and other fees and responsibilities. The terms should be negotiated between the parties verbally before an agreement is signed. The landlord is recommended to also check the prospective tenant’s background, before writing a lease, by having the tenant complete a rental application form. The tenant may be asked to pay a non-refundable fee for the application related to obtaining their credit, employment, and rental history.
