How Much Does It Cost to Sell a House - The Complete Breakdown

Most people decide to sell before they know what selling actually costs.

It usually starts with a conversation - a strong auction result down the street, a change in circumstances, a sense that the market is moving. The decision to sell is made emotionally. The full cost of that decision is discovered gradually, often after the process is already in motion.

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 Predictable Part of the Cost Stack

The two costs most vendors factor in from the start are the agent commission and the marketing spend. These are the most visible because they are discussed early in the agent selection process and quoted in writing before any agreement is signed.

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 Second Layer of Selling Costs

Every residential sale in South Australia requires a conveyancer or solicitor to manage the legal transfer of ownership. Fees sit broadly between $800 and $1,500 for a standard transaction. Some providers charge a flat fee. Others charge based on time and complexity. Getting a written quote early prevents the cost being a late discovery.

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 presentation is where the underestimation is most common. Paint touch-ups, garden tidying, carpet cleaning, minor repairs - none of these are expensive individually. As a list they add up. Vendors should walk through the property before listing with the same critical eye a buyer would use, and estimate the cost of addressing what they find. The total often surprises.

What Vendors Forget to Include in the Calculation

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.

Overlap costs apply when a vendor is buying and selling simultaneously, or when settlement dates do not align cleanly. Bridging finance, additional rent, or the cost of storage during a gap between settlement and moving all fall into this category. These costs are highly variable and depend on individual circumstances, but vendors who are buying their next property at the same time as selling should model this scenario carefully before committing to either transaction.

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.

What to Total Before You Sign Anything

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.

Common Questions About the Cost of Selling

What should I budget for when selling a house in South Australia?

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 conveyancing included in real estate agent fees?

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.

What happens to marketing costs if the property does not sell?

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 costs do most sellers forget to include?

Mortgage discharge fees, fixed-rate break costs, conveyancing, pre-sale repairs, staging, overlap costs, and removalist fees are the items most commonly absent from the initial vendor calculation. They are not hidden - they are overlooked. Identifying them before committing to sell is what separates a realistic net proceeds figure from an optimistic one.

How Selling Costs Apply in the Gawler District

Vendors selling across the Gawler District and surrounding northern Adelaide suburbs face the same cost stack as any South Australian residential seller - and the same risk of underestimating it if the calculation is left until the campaign is already underway.
