Dubai's Property Portals Face a Reckoning Over Duplicate Listings: The Key Decisions Ahead

Duplicate property listings have long been an open secret on Dubai's real estate portals, but the pressure to do something about them is now acute. The Real Estate Regulatory Agency, known as RERA, has been tightening its permit-based listing rules under the Dubai REST platform, and brokers operating across Property Finder, Bayut and Dubizzle are facing the prospect of mandatory permit number verification that would make ghost listings technically impossible to publish. The question now is how fast that enforcement kicks in, and who bears the cost of compliance.

The timing is not accidental. Dubai's property market recorded transaction volumes in 2024 that pushed the sector to historic highs, and the golden visa expansion has pulled in a new wave of international buyers who arrive expecting the kind of clean, deduplicated search experience they know from London or New York. When the same two-bedroom apartment in Dubai Marina appears twelve times across a single portal at twelve different prices, that is not a quirk — it is a liability for a city actively positioning itself as a financial hub that competes with Singapore for mobile capital and talent.

What the Portals Must Now Decide

The central technical decision facing Property Finder and Bayut — both of which hold dominant positions in the UAE's digital property advertising market — is whether to implement backend permit-number deduplication at the point of upload or at the point of display. Upload-side filtering is cleaner and more defensible to regulators, but it pushes friction onto brokerages, many of which are small operations clustered around Business Bay and Jumeirah Lakes Towers, running lean teams with limited technical capacity. Display-side filtering is easier to deploy but allows duplicate data to accumulate in databases, creating a compliance headache if RERA audits portal records rather than just live pages.

RERA's Dubai REST system already assigns a unique permit number to each listing under the Trakheesi programme. The infrastructure, in other words, already exists. The gap is enforcement of the requirement that every published advertisement carry that permit number and that each permit number appear only once per active listing cycle. Brokers who advertise without a valid Trakheesi permit are subject to fines, and RERA has publicly committed to digital enforcement mechanisms, though the specific rollout timeline for automated portal-side checking has not been confirmed in any document reviewed for this report.

The Stakes for Buyers and the Broader Market

For buyers walking into the offices of a developer like Emaar or Nakheel — or sitting in the co-working spaces of d3, Dubai Design District — the practical consequence of duplicate listings is wasted time and eroded trust. A search for apartments near the Burj Khalifa can surface the same unit at a listed price of AED 1.8 million from one brokerage and AED 2.1 million from another, not because the market is that volatile but because the same agent uploaded the same property under two different agency accounts. That price confusion feeds directly into negotiation distortions and, ultimately, into transaction delays.

The portals have commercial incentives that run in both directions. More listings mean more page views and more advertising revenue. Fewer duplicates mean higher data quality, better user retention and a stronger case to international investors who are comparing Dubai's property search tools against platforms in cities with stricter listing standards. PropTech observers note that Bayut's parent company, Dubizzle Group, has invested in data verification tools, though the extent of live deployment across all listing categories has not been publicly detailed.

Several decisions will determine how this plays out over the next six to twelve months. RERA will need to publish a definitive compliance deadline for mandatory Trakheesi integration at the portal level — something it has not yet done publicly. The major portals will need to choose their technical architecture before that deadline lands. And brokerages, particularly the hundreds of smaller agencies registered in Deira and Al Quoz, will need to audit their listing workflows and staff training. The window for voluntary cleanup is open. Regulatory compulsion is increasingly likely to follow if the voluntary route stalls.
