Marketing costs in SA
Agents usually ask for a marketing budget up front, and you pay it whether or not the property sells. In South Australia that runs $400 to $5,000 depending on the campaign: portal listing upgrades, photography, a signboard, print, and sometimes styling on top.
This is the line item sellers most often miss when they compare a percentage fee to a flat one, because it never appears in the commission rate.
Legal costs and the SA paperwork
A Form 1 vendor statement has to be served on the buyer before they sign, or at least 10 clear days before settlement. A conveyancer prepares it, usually $400 to $700 plus searches. Serving a defective Form 1 carries penalties and can give the buyer a right to walk away, so it is worth having prepared properly.
Conveyancing for a seller in South Australia typically costs $700 to $2,500 in professional fees, plus searches and government charges. You pay this whether you sell with an agent or privately, so it is not part of the comparison below.
Worked example: a typical SA sale
Take a $975,000 sale: the ABS mean dwelling price for South Australia, $973,100 in March quarter 2026, rounded to the nearest $5,000.
| What you pay | Cost |
|---|---|
| Commission at 2.3% | $22,425 |
| Marketing (midpoint of the SA range) | $2,700 |
| Agent total, before conveyancing | $25,125 |
| helm, paid once, before conveyancing | $749 |
Conveyancing is extra in both columns and costs about the same either way. The difference is what you are paying someone to do the marketing, the inspections and the negotiation for you. See what helm includes.

Cooling-off in SA
A buyer gets 2 clear business days from the later of receiving the Form 1 or signing, and the seller may keep no more than $100 of the deposit. There is no cooling-off at auction. Worth knowing before you accept an offer, because it changes when a sale is actually a sale.
Selling without an agent in SA

The one thing you cannot do as an individual is list directly on realestate.com.au or Domain, which only accept listings from licensed agents. helm's listings reach both portals through a licensed agent on the helm team, and you run the sale yourself.
