Time’s up for dodgy property guides! How homebuyers use AI to spot underquoting
- Replies 0
Some secrets in Sydney's property market have been hiding in plain sight for years.
Buyers have long suspected they were being misled—but proof was hard to come by.
Now, a new tool promises to shine a light on one of the industry's dirtiest tricks.
A buyer's agent hailed a groundbreaking website that exposes underquoting, saying it was long overdue.
Australian Property Advocates director Simon Murphy said the platform would bring 'accountability' to an industry that had become 'cooked'.
The platform, RealEstats, uses artificial intelligence to analyse property data and rank agents by how much their guide prices differ from actual sale prices.

'Everyone knows agents are lying about price guides, so I built a free tool to show just how much,' the creator realestats_sergio wrote on social media.
The website features a sortable database of agents, revealing who consistently underquotes or overestimates property values.
It also breaks down data at suburb and council level and includes affordability filters, giving buyers and sellers new transparency in one of Australia's most opaque markets.
Mr Murphy said real estate agents needed to be 'called out' over the dodgy practice.
'This is awesome. It's called accountability. It needs to happen,' he said.
He added that prospective buyers should now more than ever do their research, as underquoting was widespread across Australia.
'Stop looking at the listed price and start getting educated in the market. Start looking at the sold price,' he said.
'Underquoting has become a big issue, it's a big problem everywhere.... real estate agents have absolutely cooked this industry.'
Under New South Wales law, agents must provide a reasonable estimate of a property's likely selling price in the agency agreement.
If advertising with a price range, the upper figure cannot exceed the lower by more than 10 per cent.
Breaches can attract fines of up to $22,000.
'Agents are putting in price ranges like $900k–$990k for a property worth $1.2million. That's how they attract buyers,' Mr Murphy said.
Although there were no suggestion these agents had engaged in underquoting, but reported the disparity between guides and sold prices drawn from public data.
Underquoting is defined as a sold price being 10 per cent higher than the auction price guide.
For now, RealEstats only covers Sydney and parts of regional New South Wales, though expansion to other states could be possible.
RealEstats noted that the data was manually collected from public sources, meaning gaps, delays and errors were possible.
The results were estimates, it said, and should be considered opinion rather than fact.
Its disclaimer emphasised that not all Sydney agents were included, and inclusion or omission did not necessarily reflect professional competence.
'This material is provided for general information only and does not constitute financial, legal, or professional advice,' the site warned.
If you’re worried about property prices and dodgy guides, there are more warnings worth paying attention to.
Experts are now flagging new risks in the housing market that could affect buyers and sellers alike.
