Singapore's Property Platforms Move to Stamp Out Duplicate Listings This Week

Singapore's two dominant property portals took coordinated steps this week to address a problem that has quietly frustrated flat-hunters for years: the same unit appearing multiple times across search results, often with mismatched or recycled photographs that bear little resemblance to the actual property. The move signals a harder line on listing integrity at a moment when HDB resale prices remain stubbornly elevated and every wasted viewing appointment costs time and money.

The issue has grown acute as Singapore's resale flat market stays hot. Median resale prices in mature estates like Toa Payoh and Queenstown have hovered above S$700,000 for standard four-room units through the first half of 2026, according to HDB transaction records. When buyers research a flat online, duplicate listings with mismatched images can make a single unit appear to be three separate properties at three different prices, distorting perceived supply and inflating inquiry volumes that agents then use to pitch urgency to buyers.

What Changed This Week

PropertyGuru and 99.co both updated their listing submission guidelines on 1 July, tightening rules around image reuse. Under the revised framework, agents must now certify that photographs submitted with a new listing have not been used in any active or recently expired listing on the platform within the preceding 90 days. Listings flagged by the portals' automated detection systems are placed in a review queue before going live, rather than publishing immediately and being removed retroactively. The 90-day window was a specific sticking point in earlier industry consultations — shorter periods had allowed agents to cycle the same images through a sequence of listings just weeks apart.

The Council for Estate Agencies, which licenses and regulates property agents in Singapore, has been pushing for greater digital accountability since its 2024 review of online listing standards. CEA's Professional Standards and Development division has the authority to impose disciplinary action on agents found to be deliberately deceiving consumers, including through misleading visual representations of a property. CEA did not issue a formal directive this week, but the portal policy changes align with the direction the regulator has signalled publicly over the past 18 months.

For buyers combing listings along corridors like Clementi Avenue 3 or the newer Build-to-Order blocks in Tengah, the practical difference should be visible within weeks. Search results that previously surfaced four or five entries for a single Clementi Walk flat — each uploaded by a different co-broking agent — should consolidate into fewer, more accurate representations. That matters in Tengah especially, where a wave of completed BTO flats entered the resale-eligible pool this year and the secondary market there is still finding its price discovery footing.

The Bigger Picture for Buyers and Agents

Not everyone in the industry is pleased. Agents who rely on high listing volumes to drive web traffic to their personal brand pages argue the new image-authentication step adds friction to what is already an administratively heavy process. A single HDB resale transaction involves Option to Purchase paperwork, HDB portal submissions, CPF board declarations and bank valuations — piling compliance onto the listing stage, some agents contend, front-loads the burden before a deal is even confirmed.

The counterargument is that the burden falls mainly on agents gaming the system. An agent representing a single genuine listing has no reason to submit the same bathroom photograph six times. The duplication problem is largely a competitive-visibility tactic: the more entries a unit has, the more search-result real estate an agent occupies relative to rivals.

Buyers dealing with the current market — where the average time-on-market for a four-room resale flat in Bishan dropped to under three weeks in May 2026 — should treat this week's portal changes as a partial improvement rather than a complete fix. The 90-day image rule does not yet cover new private condominium launches, where show-flat renderings and developer-supplied images create their own category of misleading representation. CEA is understood to be reviewing that segment separately. For now, flat-hunters are advised to cross-reference listing photographs against Street View imagery and, where possible, request a video walkthrough before committing to a physical viewing.
