Listing Agent vs. Buyer Agent: Duties, Fees, and Dual Agency

A listing agent represents the seller; a buyer agent represents the buyer. Each owes fiduciary duties only to their own client, and each is paid through commissions that have always been negotiable. The practical difference between a listing agent and a buyer agent matters more than ever after a $418 million antitrust settlement reshaped how buyer agents get paid and introduced a new rule: as of August 17, 2024, no agent can tour a home with you until you’ve signed a written representation agreement.¹

What a Listing Agent Does for the Seller

A listing agent’s work starts before the sign goes in the yard. They run a comparative market analysis using recent sales of similar nearby homes, then recommend an asking price. From there they handle marketing: professional photography, MLS placement, open houses, and digital advertising aimed at qualified buyers.

The listing agent also prepares the listing agreement, a contract between the seller and the brokerage covering the asking price, the services the agent will provide, the commission the agent will earn, and the length of the exclusive marketing period.²

Beyond marketing, listing agents guide sellers through disclosures. Every state requires sellers to disclose certain material defects affecting the home’s value or safety, and a listing agent helps the seller understand what has to be disclosed and how to document it.³ Getting disclosures wrong can expose a seller to legal liability long after closing.

When offers come in, the listing agent evaluates more than price. They look at the buyer’s pre-approval letter, proof of funds, contingencies, and proposed timeline to assess which offer is most likely to close cleanly. In competitive markets they may manage multiple simultaneous offers and advise on counteroffers.

What a Buyer Agent Does for the Buyer

A buyer agent narrows the search to a client’s budget, location, and priorities, schedules private showings, and pulls historical price data on comparable properties. An experienced buyer agent catches issues in seller disclosures that most buyers miss, like unpermitted additions, drainage problems, or boundary disputes buried in the fine print.

Once a buyer picks a property, the agent drafts the purchase agreement and manages the due diligence period. That means coordinating home inspections, pest inspections, and specialist evaluations. Missing a contingency deadline can cost the buyer their earnest money deposit, typically 1% to 3% of the purchase price. Timeline management is one of the most valuable things a buyer agent does.

Appraisal gaps are another area where buyer agents earn their fee. If the lender’s appraisal comes back lower than the agreed price, the mortgage won’t cover the full amount and the buyer faces a shortfall. The agent can renegotiate with the seller, propose splitting the difference, or request a reconsideration of value if the appraisal relied on flawed comparable sales data. When the contract includes an appraisal contingency, the buyer also has the option of walking away without losing the deposit. A good buyer agent builds those protections into the contract before they’re needed.

The Fiduciary Duties Each Agent Owes Their Own Client

Real estate agents aren’t salespeople who happen to handle paperwork. They’re fiduciaries, legally required to put their client’s interests ahead of their own. Agents who violate these duties face license discipline and civil liability.

Loyalty. Your agent must prioritize your interests over their own financial gain or anyone else’s goals. A listing agent who nudges you toward a lower offer because it closes faster has breached this duty.
Confidentiality. Your agent cannot reveal information that would weaken your negotiating position. A buyer agent telling the listing side that their client would pay more has breached this duty.
Disclosure. Agents must tell you anything that could affect your decision, from a cracked foundation to planned zoning changes on the next lot.
Accounting. Any money passing through the agent’s hands, including earnest money, must be tracked and held in a brokerage trust account separate from operating funds.
Care and diligence. Your agent must bring professional-level skill. Failing to research comparable sales, missing inspection deadlines, or neglecting to present an offer all qualify as failures.
Obedience. Your agent must follow your lawful instructions, even if they’d pick a different strategy.

These duties run one direction only. The listing agent owes them to the seller; the buyer agent owes them to the buyer. Neither agent owes fiduciary duties to the other side’s client, though both owe basic honesty and fair dealing to everyone in the transaction.

How Each Agent Gets Paid After the 2024 Settlement

For decades, commissions followed a simple model: the seller agreed to a total commission (typically 5% to 6% of the sale price), and the listing brokerage split that fee with the buyer’s brokerage through a cooperative compensation offer posted on the MLS. Buyers rarely paid their agent directly because the seller’s commission covered both sides.

That system was challenged in Burnett v. The National Association of Realtors, a class action alleging the cooperative structure inflated commissions and forced sellers to subsidize buyer representation. NAR settled for $418 million and agreed to rule changes effective August 17, 2024.⁴

The biggest structural change: the MLS can no longer include any offer of buyer agent compensation. No commission field, no yes-or-no indicator, nothing about what a buyer’s agent might be paid.⁵ The main mechanism that paid buyer agents for decades is gone.

Sellers can still offer to pay the buyer’s agent, just not through the MLS. That offer can appear in flyers, emails, brokerage websites, or direct broker-to-broker communication. Seller concessions that help buyers cover transaction costs, including agent fees, can still appear on the MLS, but those concessions cannot be conditioned on or tied to payment to a buyer’s agent.⁶

Two protections to know about. Buyer agents cannot filter or hide listings based on what the seller is offering to pay, so you must be shown homes that fit your criteria regardless of the compensation on the other side.⁵ Agents also cannot delay presenting your offer while they try to negotiate their own compensation.⁷

Commissions remain fully negotiable, and always were. NAR does not set rates, and no law establishes a standard percentage.⁶ Separately, most brokerages charge a transaction or administrative fee (often $300 to $600) for document management and compliance. Whether that fee goes to the client or gets absorbed by the agent varies by brokerage. Ask upfront.

The Written Buyer Agreement You Now Have to Sign

Since August 17, 2024, any agent working with a buyer must sign a written buyer representation agreement before touring a home, in person or virtually.¹ Visiting an open house on your own or asking an agent general questions doesn’t trigger the rule. The moment you want a private showing, the agreement has to be in place.

The agreement must include:

A specific compensation amount, stated as a flat dollar fee or a percentage of the sale price. Ranges and open-ended terms are not allowed.⁵
A compensation cap. The agent cannot collect more from any source than the agreed amount. If the seller offers to pay the buyer’s agent $10,000 but your agreement says $8,000, the agent gets $8,000.⁸
A negotiability disclosure stating conspicuously that commissions are not set by law and are fully negotiable.⁵

Everything in the agreement is negotiable: the compensation, the term, and the scope of services.¹ Buyers who don’t shop around often accept the first number proposed. Interview multiple agents, compare fees and services, and negotiate before you sign.

Listing agreements have always been written contracts. The new requirement specifically brings buyer-side arrangements into the same documented, upfront format.

When One Agent Represents Both Sides: Dual Agency

Dual agency is when a single agent, or a single brokerage, represents both buyer and seller in the same transaction. On paper, the agent still owes fiduciary duties to both sides. In practice, that’s a contradiction, and roughly eight states have banned it.

The core problem is loyalty. By consenting to dual agency, both parties give up the right to undivided loyalty from their agent.⁹ The agent can no longer advocate aggressively for either side’s best price, since every dollar one client gains, the other loses. Confidential information like the seller’s bottom-line price or the buyer’s ceiling cannot be used to benefit either party, which effectively ends the agent’s ability to negotiate for anyone.

Where dual agency is legal, it requires written consent from both buyer and seller after full disclosure of the limitations.⁹ Many brokerages in those states use designated agency instead: two separate agents within the same firm each represent one side, keeping full fiduciary duties intact for each client. It isn’t perfect, because the agents share a managing broker and an office, but it’s a meaningful improvement over one person trying to serve two.

If an agent asks you to consent to dual agency, understand what you’re giving up. In most cases you’re better off with your own dedicated representative.

Ending the Relationship Early

Both listing agreements and buyer representation agreements are contracts with defined terms, and walking away before the term expires can have financial consequences.

For sellers, listing agreements often include a protection clause (sometimes called a “tail” or “carryover” period). If you cancel the listing and later sell to a buyer your original agent introduced during the listing term, that agent may still be entitled to their commission. Some agreements also include a cancellation fee to cover marketing costs already spent on photography, MLS fees, and advertising. These vary widely and should be negotiated before you sign, not when you’re trying to leave.

For buyers, written agreements also have defined terms and cancellation provisions. Some allow termination with written notice; others may require compensation for work already performed. Because mandatory buyer agreements are still new, the specific terms vary between brokerages. Read the cancellation clause before you sign, and confirm the agreement covers a specific time period, since open-ended terms are prohibited under the current rules.⁵

The cleanest exit is a mutual release: you and the agent agree in writing to end the contract with no further obligations. Most agents would rather let an unhappy client go than drag a deal toward trouble. Getting that release in writing protects you from a commission claim later.
