The Illinois residential purchase and sale agreement is a real estate contract that a buyer delivers to a seller when presenting an offer to purchase a property. Among other terms and conditions, the contract states important pricing information, disclosure requirements, deposit amounts, and the contingencies that, if not satisfied within a certain time frame, may void the agreement or require renegotiation between the parties.

It is not uncommon for the seller to reject the initial offer if the proposed sales price or other provisions are not to their liking. In these instances, the seller can advance the negotiation process by making a counteroffer, or simply ignore the proposal and let the offer expire.
