When you’re preparing to sell your property, understanding real estate agent fees is just as important as understanding the sale price itself. Real estate agent fees are not set by law, which means they are negotiable and can vary depending on where you are selling and the type of property you own.
For most sellers, the agent’s fee will be the largest single expense of the sale. That is why it is important to understand exactly what you are paying for and how real estate agent fees can influence your final outcome.
How real estate agent fees are structured
Most agencies operate on a commission-only basis, meaning the fee is only paid once the property has successfully settled. As of early 2026, the average commission in metropolitan Adelaide typically sits between 2.0% and 2.75%. In some regional or rural areas, you may find rates trending closer to 3.0%, reflecting different overheads and lower transaction volumes in those markets.
There are generally two ways real estate agent fees are calculated. A fixed commission is a set percentage of the final sale price, giving sellers a predictable cost regardless of the outcome.
Alternatively, some sellers prefer a tiered commission structure. This performance-based approach involves agreeing on a base rate up to a certain sale price, with a higher percentage applied to any amount achieved above that figure. The idea is to align the agent’s incentive with achieving the strongest possible result, rather than simply securing a quick sale.
What real estate agent fees actually cover
It is important to remember that commission is not simply a payment for listing a property. Real estate agent fees cover the professional service involved in managing and negotiating the sale.
This typically includes the agent’s time and expertise, their network of active buyers, coordinating inspections, managing enquiries, and negotiating between buyers and sellers. In the current market, agents are also responsible for managing strong digital interest and navigating multiple offers in what can often be a fast-moving environment.
A skilled agent’s role is ultimately to bridge the gap between what a buyer is prepared to pay and the result a seller is hoping to achieve.
Marketing costs and the Form 1
One of the most common points of confusion when selling property is the difference between real estate agent fees and marketing costs.
Marketing is usually a separate expense and typically includes professional photography, floorplans, and premium listings on major real estate portals.
Additionally, South Australian law requires the preparation of a Form 1, also known as the Vendor’s Statement. This document must be accurate and provided to the buyer before a sale can proceed.
The government searches required to complete the Form 1 are usually organised by a conveyancer or solicitor and billed separately from the agent’s commission. These costs are a mandatory part of the selling process.
Understanding real estate agent fees
Ultimately, the right commission structure is the one that aligns your agent’s goals with your own to achieve the best possible outcome for your property.
By understanding real estate agent fees, along with the difference between professional fees and marketing investments, sellers can approach the process with greater confidence and clarity.
