The Illinois Residential Rental Application exercises the use of an obligatory questionnaire to delineate necessary information on a potential lessee to ascertain qualification for a property lease. The circulated paperwork is then evaluated to examine the possibility of tenancy for the applicant. The gathered information within the document covers the possible tenant, their rental, work, and criminal history as well as current monthly income. Ordinarily, all those that will be residing on the property will be obligated to fill out an application for submission as the examination of total household income and background of each individual will be needed prior to lessor consideration. Should the applying individual meet the requisites for the property, a lease agreement can be drawn up and contracted for endorsement. Keep in mind that it is common practice for a landlord or property management company to request a non-refundable application fee to cover the cost of a lessee background investigation.
