The decision comes first - prompted by a life change, a market update, a conversation with a neighbour who just sold well. The emotional commitment is made. Then, somewhere between signing the agency agreement and settlement day, the full cost of the transaction reveals itself. For many vendors, that revelation is uncomfortable.
The cost of selling a house in Australia is not a single number. It is a stack of costs - some visible and predictable, some less obvious, and some that only appear once the process is already in motion. Understanding the full stack before making the decision to sell is not pessimism. It is the calculation that determines whether the timing actually makes sense.
The Two Costs Vendors Always Know About
Most vendors begin the cost calculation with commission and marketing. These are the visible costs - negotiated before the campaign starts, confirmed in writing, and easy to compare across agents.
Agent commission in South Australia is typically quoted as a percentage of the final sale price, inclusive of GST. Depending on the agency model, that rate ranges broadly from around one percent for independent agencies to closer to three percent for some franchise networks. On a $750,000 sale, the difference between 1.5 percent and 2.5 percent is $7,500 - a gap that is worth understanding before signing.
Marketing spend covers photography, floor plans, and portal presence - the presentation layer that determines how many buyers engage with the listing. Whether this is included in commission or charged separately varies by agency. Confirming this in writing before signing prevents the surprise invoice arriving mid-campaign.
Together, commission and marketing form the most predictable part of the cost stack. The less predictable costs sit beneath them.
The Costs Below the Surface
Conveyancing covers the legal transfer of ownership at settlement. In South Australia it is a required step for every residential property sale, and the cost varies by provider and transaction complexity. Budgeting $800 to $1,500 for a standard sale is a reasonable starting estimate - though vendors should request a written quote before committing to a conveyancer.
Property styling and staging is an expense that a growing number of vendors choose to incur but fewer anticipate before they start the process. Professional staging - bringing in furniture and styling a property for photography and open inspections - typically costs between $2,000 and $5,000 depending on property size and the scope of the work. Partial styling, where a stylist works with existing furniture, sits at the lower end. Full furniture hire for a vacant property sits at the higher end.
Pre-sale repairs and presentation work is the cost that most vendors underestimate. A fresh coat of paint, garden tidying, minor fixture repairs, carpet cleaning - these are the items that an agent will often recommend before photography and open inspections begin. Individually they are manageable. Collectively they can add $1,000 to $5,000 to the cost of selling depending on the condition of the property and how much maintenance has been deferred over the years.
The Final Layer - Costs That Arrive Late
Mortgage discharge fees apply when a property being sold has an existing mortgage. The lender charges a fee to release the mortgage at settlement. This fee varies between lenders but typically sits between $150 and $500. It is not a large cost individually, but it is one that consistently surprises vendors who assumed the mortgage simply disappears at settlement without a cost attached.
Vendors with fixed-rate home loans may also face break costs if the loan is paid out before the fixed term expires. These costs vary significantly depending on the lender and prevailing interest rates at the time of payout and can in some cases be substantial. Vendors with fixed-rate loans should confirm the break cost position with their lender before committing to a sale timeline.
Capital gains tax generally does not apply to a principal place of residence, but it may apply if the property being sold is an investment or has not always been used as the the vendor main residence. The rules are specific and the liability can be significant. Vendors who are unsure of their position should seek taxation advice before calculating expected net proceeds.
Vendors buying and selling at the same time face an additional layer of cost if settlements do not align. Bridging finance, temporary storage, and short-term accommodation are all potential expenses in this scenario. Modelling the overlap before committing to either transaction is the step that prevents the situation becoming a financial problem.
Moving costs are the line item that almost every budget omits until the removal quote arrives. Professional removalists for a three to four bedroom house typically cost between $800 and $2,500 depending on distance, volume, and whether packing services are included. For interstate moves the figure is substantially higher.
The Exercise That Produces an Accurate Net Figure
A sale price estimate tells a vendor what a buyer might pay. A net proceeds calculation tells them what they will actually keep. The difference between the two is the full cost stack - and building that calculation before signing anything is where the decision-making process should begin.
The exercise is straightforward:
- Get a written commission and marketing quote from each agent you interview and confirm what is and is not included
- Request a conveyancing fee estimate before signing the agency agreement
- Walk through the property and estimate the cost of any presentation or repair work required before listing
- Confirm with your lender whether a mortgage discharge fee applies, and whether break costs apply if you are on a fixed rate
- If the property is not your principal place of residence, seek taxation advice on capital gains liability before calculating net proceeds
- Model your moving costs before settlement day rather than after
Each of these steps takes less time than a single agent meeting. Together they produce a net proceeds figure the vendor can actually rely on.
The total cost of selling a house varies by property, agency model, and individual circumstances. For a typical suburban property in South Australia, the full cost stack often sits between three and five percent of the sale price when everything is counted. On a $750,000 property that is between $22,500 and $37,500.
The sale price is what your property sells for. Net proceeds are what you take home. The difference between those two numbers is the calculation worth completing before the decision is made.
Frequently Asked Questions
How much does it cost to sell a house in SA?
The full cost of selling varies depending on agent commission rate, marketing spend, conveyancing fees, presentation costs, and individual circumstances. As a broad guide, vendors should budget between three and five percent of the sale price to cover all costs from listing to settlement. On a $750,000 property that range sits between $22,500 and $37,500. Properties requiring significant pre-sale work or vendors using higher-commission agencies will sit toward the upper end of that range.
Is legal work included in the agent commission?
No. Agent commission and conveyancing are separate costs. The agent manages the sale campaign and negotiation. The conveyancer or solicitor manages the legal transfer of ownership at settlement. Both are required for a residential sale in South Australia and both should be budgeted for separately before the campaign begins.
Can I get a refund on marketing if the sale falls through?
This depends on the terms of the agency agreement. In most cases, commission is only payable on a successful sale. However, marketing costs - photography, portal listings, print advertising - are often non-refundable once incurred regardless of outcome. Vendors should read the agency agreement carefully and understand which costs are contingent on a successful sale and which are not before signing.
What are the hidden costs of selling a house?
The costs that most commonly surprise vendors are mortgage discharge fees, fixed-rate loan break costs, pre-sale presentation and repair work, property styling, capital gains tax on non-principal residences, overlap costs when buying and selling simultaneously, and moving costs. None of these are genuinely hidden - they are simply not discussed in the early stages of the selling process. Building them into the cost estimate before making the decision to sell produces a more accurate picture of what the transaction will actually return.
