Whether the acceptance deadline in the buyers' original offer became a term of Miller's counteroffer, making the counteroffer an irrevocable option until 5:00 p.m. on August 5.
Holding
No. Miller's materially altered response was a counteroffer, not an acceptance incorporating every unaltered term of the buyers' original offer, and it did not promise to remain open for any fixed period.
Reasoning
A contract requires mutual assent to the same bargain. A seller who accepts an offer only after materially changing its payment or other terms has not accepted the original offer; the qualified response rejects that offer and proposes a new bargain. Miller's changes to the deposit, down payment, mortgage amount, loan term, and buyer qualification were material, so her signed response was a counteroffer.
The original offer's 5:00 p.m. deadline limited Miller's power to accept the buyers' offer. It did not automatically limit the duration of the distinct counteroffer that Miller made after rejecting that offer. Miller's counteroffer manifested no intent to accept the original offer, including its deadline, unless the buyers agreed to her substituted terms.
An option requires, among other things, a promise by the property owner to give the other party an exclusive right to buy at a stated price within a specified time. Miller made no express promise to hold her counteroffer open, nor did she agree to convey the property if the buyers accepted by a particular deadline. Because that essential promise was absent, the Court did not need to decide whether her signature under seal supplied consideration sufficient to support an option.
