The Illinois Affordable Housing Documentation Checklist is a list of documents required in order to apply for affordable housing in the state of Illinois. This checklist includes documents such as proof of identity, income verification, rental history, and other documents that the housing authority may require for the application process. There are two types of Illinois Affordable Housing Documentation Checklists: one for applicants and one for landlords. Applicants must provide documents such as a valid ID, proof of income, proof of residency, social security card, bank statements, tax returns, and any other documents that may be requested by the housing authority. Landlords must provide documents such as rental agreement, lease agreements, proof of occupancy, and other documents that may be requested by the housing authority. All documents must be current, valid, and up to date in order to be accepted. Applicants and landlords must also complete the Illinois Affordable Housing Documentation Checklist in order to be considered for affordable housing in the state.
