Yes. Under common law, a counter offer voids the original offer the moment you send it, and you lose the right to go back and accept the original terms. The person who made the first offer would have to put those terms back on the table voluntarily. Two situations change this result: contracts for the sale of goods under the Uniform Commercial Code, and option contracts where the offer has been paid to stay open.
The Common Law Rule
For services, real estate, employment, and most contracts that do not involve physical goods, the “mirror image rule” controls. An acceptance has to match the original offer exactly. Any response that changes the terms operates as a rejection of the original offer and creates a new offer running the other direction. The Restatement (Second) of Contracts § 39 states the rule this way: a counter offer terminates the offeree’s power of acceptance, because negotiating parties usually understand that one proposal drops off the table when another goes on it.
A simple example. A seller offers a vehicle for $10,000. The buyer responds with $9,500. That response kills the $10,000 offer. If the seller says no to $9,500, the buyer cannot circle back and say “fine, I’ll take it for $10,000.” The buyer would need the seller to voluntarily reoffer at $10,000.
The same logic applies in real estate. If a homebuyer receives an offer to sell a property “as-is” and responds that they will accept only if the seller pays for a home inspection, the inspection condition rejects the original deal. The “as-is” offer is gone.
What Actually Counts as a Counter Offer
Not every response to an offer terminates it. Getting the distinction wrong is how people accidentally kill deals they wanted to keep.
Inquiries and Requests for Clarification
Asking a question about the terms does not kill the original offer. “Would you consider $9,500?” is an inquiry. You have not committed to paying $9,500 or rejected the $10,000 price. “Does the price include the furniture?” is a request for clarification. The original offer stays open because you are gathering information, not proposing new terms.
Language matters here. “Would you take $9,500?” keeps the original alive. “I’ll give you $9,500” does not. The first explores flexibility; the second proposes a substituted deal. Courts look at whether the response shows an intent to reject the original terms or merely an interest in learning more.
Conditional Acceptance
A conditional acceptance sits between a clean acceptance and a counter offer, and courts generally treat it as a counter offer. “I accept, but only if you also include free delivery” is not an acceptance. It is a proposal for a different deal with an added condition, and the original offer terminates.
This catches buyers off guard in real estate. Writing “I accept the purchase price, subject to the seller completing certain repairs” feels like an acceptance, but the added condition makes it a counter offer that voids the seller’s original proposal.
The UCC Rule for Sales of Goods
Contracts for the sale of goods follow the Uniform Commercial Code rather than the mirror image rule. Under UCC § 2-207, a response that adds or changes terms can still count as a valid acceptance, as long as it is a clear expression of agreement and is not “expressly made conditional on assent to the additional or different terms.”1Legal Information Institute. Uniform Commercial Code 2-207 – Additional Terms in Acceptance or Confirmation The UCC assumes the parties have a deal unless the response explicitly says otherwise.
What happens to the extra terms depends on who is involved. Between two merchants (businesses that regularly deal in the type of goods being sold), additional terms automatically become part of the contract unless the original offer limited acceptance to its exact terms, the new terms would materially change the deal, or the original offeror objects within a reasonable time.1Legal Information Institute. Uniform Commercial Code 2-207 – Additional Terms in Acceptance or Confirmation Material changes include altering the price, quantity, or quality of the goods.
When at least one party is not a merchant, additional terms are treated as proposals the original offeror can accept or reject. They do not become part of the contract automatically. So if a company offers to sell 1,000 widgets at $5 each with 30-day delivery, and the buyer agrees on price but asks for 60-day delivery, a contract likely exists. The delivery change is a proposal the seller can take or leave.
The critical dividing line: if the response says “I accept, but only if you agree to these new terms,” that language makes it expressly conditional. No contract forms, and the response functions as a counter offer just like it would under common law.1Legal Information Institute.

Option Contracts and Firm Offers
The big exception to the rule that counter offers kill the original offer is the option contract. When an offeree has paid for the right to keep an offer open for a specific period, the offer becomes irrevocable during that window. Under Restatement (Second) of Contracts § 37, the power of acceptance under an option contract is not terminated by a counter offer, a rejection, or even the death of the offeror.
This shows up often in real estate and commercial leasing. A developer might pay $5,000 for a 90-day option to purchase a parcel of land at a set price. During those 90 days, the developer can make counter offers, explore alternatives, and negotiate aggressively without any risk of losing the original option. The seller is bound to honor the option price until the period expires.
The same principle applies to firm offers under UCC § 2-205. When a merchant makes a signed, written offer to buy or sell goods and promises to keep it open, that offer cannot be revoked during the stated period, or for a reasonable time up to three months if no period is stated.2Legal Information Institute. Uniform Commercial Code 2-205 – Firm Offers A counter offer from the other side does not cancel a firm offer any more than it cancels a paid option.
Bringing the Original Offer Back
Once a counter offer terminates the original offer, only the original offeror can bring it back. The person who made the counter offer has no power to revive the deal they killed. The original offeror has four choices:
- Accept the counter offer, forming a binding contract on the new terms.
- Reject the counter offer, ending negotiations with both the original and the counter offer dead.
- Make a new counter offer, continuing the cycle.
- Restate the original terms, which creates a brand-new offer identical to the first one.
That last option is worth understanding. When the original offeror “revives” the offer, they are technically making a fresh offer with the same terms. It is not the old offer returning. Any deadline from the original offer does not carry over; the new offer gets its own acceptance window.
This is where most people run into trouble in real estate. A buyer counters, the seller rejects, and the buyer assumes they can fall back on the original listing price. They cannot. The seller would need to issue a fresh offer, and there is no obligation to do so.
When a Counter Offer Has to Be in Writing
Verbal counter offers work for most informal negotiations. But when the Statute of Frauds applies, both the original offer and any counter offer generally need to be in writing to be enforceable. The Statute of Frauds covers real estate transactions, contracts that cannot be performed within one year, and several other categories. In nearly every state, a verbal counter offer on a house purchase is not enforceable, even if both sides shook hands on it.
Counter offers made by email or text message are valid. The Electronic Signatures in Global and National Commerce Act provides that a contract or signature cannot be denied legal effect solely because it is in electronic form.3Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity An emailed counter offer on a real estate deal can satisfy the writing requirement, though using the standard forms provided by your agent or attorney is the safer practice.
