The property
A four bedroom brick home on 922sqm at the foot of the Southern Flinders Ranges, with two separate living zones and the serious shedding regional buyers ask for. The front and back fences had been replaced the year before.
What the valuation said
The owner ran a free AI valuation on 8 July. The automated comparable model returned $460,000 to $620,000. The Unreserved layer narrowed that to $515,000 to $595,000 with a midpoint of $555,000, rated high confidence, weighting the land size and the new fencing.
She listed at $555,000. That is the AI midpoint to the dollar.

What the campaign did
The listing drew 513 views on realestate.com.au in its first full week.
Nine enquiries arrived by email, six of them inside the first seven days, split across realestate.com.au, Domain and a third portal. The AI phone line connected eight buyer calls directly to the owner’s mobile, three of them on a single day.
That phone number matters more than most private sellers expect. Those calls arrived on weekdays during working hours, and a seller without a receptionist would have missed most of them. Every one was answered, matched to the property and put through live. Nobody hit a voicemail.
A buyer’s agent submitted a written offer three days after the campaign opened. The owner took an inspection before committing, and the sale was agreed on day seven. Contracts were signed on 31 July and the sale settled on 28 August.

What it cost
The owner paid $900, made up of Unreserved Lite, $350 to go live and $550 on sale. A commission at a typical South Australian selling rate would have been more than ten times that. The sale price is not published here at the owner’s request, so the exact difference is not shown.
Key takeaways
