When a home is sold, there is no universal rule requiring one party to pay every real estate commission. The seller and listing broker agree on the listing-side compensation, while a buyer and buyer’s broker establish their own compensation arrangement. Depending on the transaction, some buyer-broker compensation may also be paid by the seller or listing broker if the parties agree.
For San Diego County home sellers, the important point is that real estate commissions are negotiable. Who ultimately pays which brokerage costs depends on the agreements and negotiations involved in the sale. Current MLS rules also prohibit offers of buyer-broker compensation from being displayed through the MLS itself.
Does the Seller Pay the Listing Broker?
Usually, the seller enters into a listing agreement that establishes what the listing brokerage will be paid for representing the seller.
That compensation might be structured as a percentage of the sale price, a flat fee, or another agreed-upon arrangement.
There is no government-set commission rate that a seller must pay. Broker compensation is negotiable between the broker and the client.
This distinction is particularly important when comparing a traditional percentage-based listing arrangement with a flat-fee model. The structure of the listing-side fee can directly affect the seller’s estimated proceeds from the sale.
Who Pays the Buyer’s Real Estate Agent?
The answer depends on the transaction.
A buyer’s agreement with the buyer’s broker establishes the compensation arrangement for the services being provided. Current MLS policy requires written buyer agreements before an MLS participant working with a buyer tours a home, and the agreement must address compensation in an objectively ascertainable way.
That does not necessarily mean the buyer will personally pay the entire amount out of pocket.
Depending on the transaction and negotiations, buyer-broker compensation may come from:
- the buyer
- the seller
- the listing broker
- a combination of permitted sources
The buyer’s broker cannot simply assume that the seller or listing broker will pay the buyer’s brokerage costs.
Does a Seller Have to Pay the Buyer’s Agent?
No. A seller is not automatically required to offer compensation to the buyer’s broker.
A seller may decide that offering buyer-broker compensation makes sense as part of the sale, but that is a decision to evaluate rather than a mandatory charge attached to every listing.
If buyer-broker compensation is going to be offered or paid through the listing side, current MLS policy requires the seller’s written authority, with the amount or rate disclosed in advance.
This is one reason sellers should separate two questions:
What am I paying my own listing brokerage?
and
Am I agreeing to contribute toward the buyer’s brokerage cost?
They are not necessarily the same expense.
For a closer look at the buyer-side question, see whether a seller has to pay the buyer’s real estate agent.
Can Buyer-Agent Compensation Be Negotiated in an Offer?
Yes. Compensation can become part of the economics being negotiated around a transaction.
For example, a buyer-broker agreement may establish compensation terms, and the buyer may seek seller assistance with that expense as part of an offer.
The seller can then evaluate that request along with the rest of the offer.
That means the useful question is not simply whether a seller is being asked to pay something. The seller should consider the entire economic package: purchase price, financing, contingencies, requested credits or concessions, closing terms, and any requested contribution toward buyer-broker compensation.
For example, a $900,000 offer with $10,000 in seller-paid costs may produce a better net result than a $910,000 offer asking the seller to pay $25,000 in costs. Price matters, but so does what the seller is being asked to pay.
The strongest offer on paper is not always the offer that produces the strongest net result for the seller.
Can Buyer-Agent Compensation Be Offered Through the MLS?
No.
Under current MLS rules, offers of compensation to buyer brokers cannot be placed on the MLS. That change has been in effect since August 2024 and remains reflected in 2026 MLS policy.
That does not mean buyer-broker compensation is prohibited.
A seller may still authorize compensation, and permitted offers of compensation can be communicated outside the MLS through methods such as brokerage websites, signs, flyers, emails, or other communications. Compensation can also be addressed through negotiations surrounding an offer.
The distinction matters:
Buyer-broker compensation can still exist. It simply cannot be offered through the MLS itself.
Are Real Estate Commission Rates Fixed?
No.
There is no standard commission rate established by law. Compensation for brokerage services is negotiable.
For the California-specific question, see how real estate commissions are negotiated in California.
A seller should therefore understand exactly what the listing agreement requires rather than assuming there is a universal percentage that every brokerage charges.
The same principle applies to buyers. Their brokerage agreement should identify how their broker will be compensated and what financial responsibility the buyer may have.
How Do Commissions Affect a Seller’s Net Proceeds?
Brokerage compensation is one of several expenses that can affect how much money a seller receives at closing.
A simplified way to think about the calculation is:
Sale price
− mortgage and other applicable payoffs
− seller closing costs
− agreed brokerage compensation
− other seller-paid expenses or credits
= estimated net proceeds
The actual closing statement may contain additional charges or adjustments depending on the property and transaction.
For the complete calculation, see how to calculate net proceeds from selling a home.
This is why sellers should compare the cost of representation in dollars rather than looking only at a commission percentage.
What Should San Diego County Sellers Compare?
Before signing a listing agreement, understand both the compensation and the services attached to it.
A lower fee does not automatically make one arrangement better, just as a higher fee does not automatically mean better representation. Sellers should compare what they receive for the amount being charged, including pricing guidance, MLS exposure, marketing, offer review, negotiation, transaction management, and support through closing.
For sellers considering a different listing-cost structure, DMT’s flat fee MLS guides explain how flat-fee listing models work and how they differ from percentage-based arrangements.
Final Thoughts
So, who pays real estate commissions when a home is sold?
There is no single answer that applies to every transaction. Sellers generally establish compensation for their own listing brokerage through the listing agreement. Buyers establish compensation terms with their own broker. A seller or listing broker may also agree to contribute toward buyer-broker compensation, but that compensation is negotiable rather than automatically required.
For a home seller, the better approach is to understand each potential brokerage expense separately and then evaluate what the entire transaction will cost—and what you are receiving in return.
