Counter Offers, Explained: SCO, BCO and the Multiple Counter

A counter is a new offer, and the old one is gone

The legal foundation first, because it surprises people: under California law an acceptance must be absolute and unqualified, and a qualified acceptance is a new proposal. The moment a seller counters your offer, your original offer is legally dead. You cannot later accept your own original terms, and the seller cannot resurrect them either; everything now runs through the counter. The same is true in reverse each time a buyer counters back. Negotiations are a chain of fresh offers, each one replacing the last, which is why the forms are numbered and why sloppy paperwork in a long negotiation creates genuine ambiguity about what the final contract says.

The three forms: the seller counter offer (SCO), used by a seller responding to one buyer; the buyer counter offer (BCO), used by a buyer responding to a seller's counter; and the seller multiple counter offer (SMCO), built for countering several buyers simultaneously. The standard seller counter states on its face that it may not be used as a multiple counter, and the distinction is not cosmetic, as we will get to.

Mechanically, each counter changes only what it says and carries everything else forward from the documents beneath it. One built in rule worth knowing: when a counter changes the price, the down payment and loan amount adjust in proportion unless the parties say otherwise, so a price bump does not silently rewrite your financing structure.

The clock: three days, five o'clock, personal receipt

Under the printed default, a counter offer expires, and is deemed revoked with any deposit returned, unless the signed acceptance is personally received back by the countering party or their authorized agent by 5:00 PM on the third day after the counter was signed. The blank can be filled with any other date and time, and in fast markets it often is, sometimes measured in hours.

Note the standard: personally received. Signing is not acceptance; delivery is. A buyer who signs a counter at 4:40 PM on the last day and whose agent emails it at 5:20 has accepted nothing. Agents live by these timestamps for good reason, and the rule cuts in both directions on every counter in the chain.

Until acceptance is received, the party who issued the counter remains free. A seller who has countered one buyer retains the right to keep marketing the property and to accept a different offer outright, which revokes the outstanding counter. This is the quiet risk in slow deliberation: the counter in your hands is not an option contract, it is a revocable offer, and the house can be sold out from under it while you think.

The multiple counter's two step, and why the house is not yours yet

When several offers arrive, a seller choosing to negotiate with more than one buyer uses the multiple counter offer, which discloses to each recipient that other buyers are being countered, on terms that may or may not be the same. Different terms to different buyers is expressly allowed and entirely common: one buyer may be countered on price, another on a shorter escrow or a larger deposit.

Here is the part every buyer must understand before signing one: accepting a multiple counter does not form a contract. The SMCO binds no one until the seller makes a final selection. The sequence runs: the seller issues the multiple counters; a buyer signs acceptance, which must be received within the three day default window; and then the seller selects, signing again in a dedicated selection section, with the buyer's acceptance itself deemed revoked if the seller's signed selection is not made and delivered back, by default, by 5:00 PM on the fourth day after the counter was issued. A binding agreement exists only when a copy of the seller's signed selection is personally received by the buyer. Two buyers can both "accept" the same multiple counter; only the one the seller selects has a deal.

Why the elaborate dance? Because the alternative is dangerous for sellers. A seller who issues ordinary counters to several buyers at once can be accepted by more than one, and is then contractually bound to sell one house to two parties, a mess that ends in cancelled deals, damages exposure and specific performance claims. The multiple counter exists precisely so a seller can negotiate broadly while committing to no one until the final signature. Buyers resent the asymmetry, understandably; the compensation is disclosure, since the form tells you plainly that you are competing.

Strategy on both sides of the table

For sellers, multiple counters are leverage with a cost. They push price and terms upward, and they also push some buyers away entirely, since a portion of buyers will not bid against unseen competition on principle. The deeper risk is valuation: a price bid up in a multiple counter situation still has to appraise if the winning buyer finances, and a buyer stretched past the comparables either needs an appraisal contingency resolved in their favor or cash to bridge the gap. A seller selecting among offers should weigh the certainty of each buyer, deposit size, financing strength, contingency terms, as heavily as the headline number; the strongest number with the weakest buyer is often the most expensive choice. Offers are also evaluated on terms alone, never on who the buyers are, both as law and as basic practice.

For buyers, the multiple counter is a decision about your ceiling, made once. Respond with the strongest package you can stand behind, assume you will not get a second look, and resist terms you cannot actually perform, because the deposit rules in our contingency removal guide apply with full force to whatever you sign here. Shortened contingencies and larger deposits win multiple counters, and they are real commitments, not decoration. The one mistake to never make: assuming your signed acceptance of a multiple counter means you can stop looking. Until the seller's selection is in your hands, you have no contract, and the better posture is to keep your search alive.

A good share of the multiple offer chaos is avoidable on the buy side by arriving early. Much of my work is getting clients to properties before the crowd forms, including sales that never reach the open market, which is its own discipline covered in our off market guide. And buyers calibrating how aggressive a counter response should be need current comparable data by enclave, which is what the price bands guide and our neighborhoods directory are for.

Common Questions

How long do I have to accept a counter offer in California?

Unless a different deadline is written in, the standard forms give you until 5:00 PM on the third day after the counter was signed, and your signed acceptance must be personally received by then, not merely signed or sent.

Can the seller accept another offer while their counter to me is outstanding?

Yes. A counter is not an exclusive commitment. Until your signed acceptance is received, the seller can continue marketing and can accept a different offer, which revokes the counter you were holding.

I signed the seller's multiple counter offer. Why is the house not mine?

Because a multiple counter binds no one until the seller signs the final selection and that signed selection is delivered back to you. Your signature was step one of a two step acceptance; the seller choosing you is step two.

Does countering cancel the original offer? Can we go back to it?

Yes, and no. A counter is legally a rejection plus a new offer, so the original terms are extinguished. If both sides want the original deal after all, the way back is a fresh counter restating those terms.

Can a seller counter different buyers at different prices?

With the multiple counter form, yes. The form tells each buyer that others are being countered on terms that may or may not be the same, and sellers routinely tailor each counter to each offer's weaknesses.

Can a seller back out after signing a counter offer?

Before the buyer's signed acceptance is received, yes, a counter can be revoked or superseded by accepting another offer. After acceptance is received, a contract exists and walking away has the consequences of breach, including exposure to specific performance.

Counter strategy is where transactions are won, and it rewards preparation over bravado: knowing the property's real value, the competing field, and exactly what the forms commit you to before the clock starts. I run this process for buyers and sellers across Los Angeles.
