How Singapore's Property Listings Became Overrun With Copied Images — And Why the Fixes Have Been Years in the Making

Walk through any HDB listing on PropertyGuru or 99.co today and you will occasionally spot something odd: the same photo of a Bishan four-room flat appearing on three separate listings, each claiming a different address and a different asking price. It is not a glitch. It is the tail end of a practice that agents, portals, and regulators have spent the better part of twelve years trying to stamp out — and which has resurfaced with new urgency as artificial intelligence tools make image duplication faster and harder to detect.

The issue matters now because Singapore's resale HDB market hit a median cash-over-valuation of roughly $32,000 per transaction in the first quarter of 2026, according to HDB flash data released in April. Buyers are making six-figure decisions, often remotely, based almost entirely on listing photographs. A recycled or outright stolen image — whether from a competitor's portfolio, a staging company's showroom, or a property sold years earlier — distorts that decision in ways that cost real money.

The Long Road to Where We Are

The roots of the problem go back to the early 2010s, when Singapore's property portals expanded aggressively after the 2009 market rebound. Agents listing on multiple platforms — PropertyGuru, SRX, iProperty, and later 99.co — quickly discovered that uploading identical image sets across portals was not only permitted but effectively encouraged by portal incentive structures that rewarded listing volume. The Council for Estate Agencies, established under the Estate Agents Act in 2010, focused its early enforcement energy on disclosure obligations and commission disputes rather than image provenance.

By 2018, a CEA audit of 4,200 listings found that roughly 14 percent contained photographs that could not be verified as taken at the advertised property. The audit, conducted with assistance from the Singapore Polytechnic School of Architecture and the Built Environment, flagged duplicate images as the single most common form of listing misrepresentation — ahead of incorrect floor area claims and outdated renovation photos. The CEA issued advisories. Portals promised algorithmic checks. The problem did not go away.

What changed the calculus was the Housing and Development Board's push from 2023 onward to digitise the full resale transaction pipeline through the HDB Resale Portal. By requiring agents to link listing photographs to verified unit addresses tied to MyInfo credentials, HDB created, almost accidentally, the infrastructure needed to cross-reference images at scale. PropertyGuru announced a partnership with the Infocomm Media Development Authority in March 2025 to pilot reverse-image verification against a centralised property photo registry hosted at one-north, in the Buona Vista technology cluster.

What the Industry Is Doing About It Now

The IMDA pilot wrapped its first phase in May 2026, covering approximately 11,000 listings across Tampines, Woodlands, and the Queenstown estate — three of Singapore's highest-volume resale towns. Early results, shared at an IMDA briefing at the Mapletree Business City auditorium in May, showed that automated duplicate detection flagged about 8 percent of listings for manual review, down from the 14 percent baseline identified in 2018. That is progress, but agents and consumer advocates note the system still relies on voluntary portal participation.

99.co has already integrated the registry API into its backend upload flow as of June 2026. PropertyGuru's full integration is scheduled for the third quarter of this year. ERA Realty and PropNex, the two largest agency networks by headcount in Singapore, have both updated their internal listing compliance guidelines to require agents to certify that photographs are original and taken within 90 days of the listing date.

For buyers and renters navigating the market right now, the practical advice is straightforward: use Google's reverse image search or TinEye before putting down any option fee or good faith deposit, request that agents confirm the photograph metadata shows a date consistent with the listing, and verify the unit address against the HDB Map Services portal, which displays approved floor plans for most HDB blocks. The plumbing to stop duplicate images at the source is nearly in place. Until full adoption lands, the onus remains with the buyer.
