The Cornillies listed with a real estate agent a home for sale. Patrick and Anne Giannetti offered $155,000 for the home and submitted a deposit in the amount of $2,500. The Cornillies countered this offer with an offer to sell the house for $160,000. The Giannettis then inquired whether certain equipment and items of furniture could be included with the sale of the house. The Cornillies refused to include the questioned items in the sale. The Giannettis then accepted the $160,000 offer but changed the mortgage amount from $124,000 to $128,000. Is there a binding contract? Explain.
