An Illinois real estate purchase agreement (also called the Illinois residential sales contract) is a legally binding document that outlines the terms and conditions under which a buyer agrees to purchase residential property from a seller in the State of Illinois. It becomes enforceable once both parties sign it and, in most cases, the buyer delivers earnest money.
Illinois is an attorney review state, which means that even when using the popular Multi-Board Residential Real Estate Contract 7.0 (the standard form created by the Illinois Realtors association), buyers and sellers have a mandatory 3-5 business day attorney review period after acceptance. This unique feature protects both parties and is one reason why using a properly drafted IL real estate contract is essential.
Generic online templates from national sites often miss crucial Illinois disclosures and statutory requirements. Using the wrong form can lead to:
My free Illinois real estate contract PDF includes all of these mandatory provisions and is updated for 2025 compliance.
The contract must clearly identify the buyer(s), seller(s), and include the full legal description of the property. In Illinois, the Permanent Index Number (PIN) and exact street address are both required.
Illinois law does not set a required earnest money amount, but 1-3% of the purchase price is customary. The funds must be held in an escrow account by a licensed Illinois escrowee (real estate broker, title company, or attorney).
Paragraph R-30 of the standard Multi-Board 7.0 contract provides the mandatory attorney review period. My template includes this exact language:
"Within three (3) business days after the Acceptance Date, Buyer's attorney may propose modifications... If no agreement is reached within five (5) business days, this Contract shall be null and void."
