Dubai's Property Portals Are Drowning in Duplicate Listings — and the Numbers Prove It

Roughly one in every five property listings on Dubai's major real estate aggregators is a duplicate, according to an internal audit methodology described by compliance officers at multiple brokerage firms active on the Dubai Land Department's approved portals. The problem is not new, but the scale has grown sharply as the emirate's megaproject construction pipeline — from Dubai Creek Harbour to the Mohammed Bin Rashid City parcels along Al Khail Road — floods the market with new off-plan inventory that brokers race to list, often repeatedly, under marginally different descriptions.

The timing matters. Dubai recorded more than 43,000 residential transactions in the first half of 2025, and preliminary DLD figures circulating among real estate analysts suggest 2026 is tracking above that pace. When duplicate images and recycled listing copy inflate the apparent supply of two-bedroom apartments in areas like Jumeirah Village Circle or Dubai Marina, both retail buyers and institutional funds making allocation decisions are working from distorted data. A fund pricing a bulk acquisition off portal-level supply figures could be off by a material margin before it even opens negotiations.

How the Duplication Happens — and What It Costs

The mechanics are straightforward. A single developer unit — say, a studio in a tower under construction near the Expo 2020 legacy district in District 2020, now rebranded as a commercial and residential cluster around Sheikh Mohammed Bin Zayed Road — gets listed by the master broker, then separately by three or four sub-agents all holding the same marketing rights. Each agent uploads the same four render images, tweaks the headline price by a few thousand dirhams, and the portal's algorithm treats it as a distinct property. Bayut and Property Finder, the two dominant portals in the UAE market, both operate image-fingerprinting systems intended to flag these cases, but enforcement is inconsistent and the fines for non-compliance — typically in the range of AED 500 to AED 2,000 per offending listing depending on the portal's tier structure — are low enough that some brokerages treat them as an acceptable overhead cost.

The Real Estate Regulatory Agency, known as RERA and operating under the Dubai Land Department on Baniyas Road in Deira, introduced the Trakheesi permit system partly to create a unique reference number for every listing. In theory, no two listings should carry the same Trakheesi permit. In practice, permits issued for off-plan units are sometimes shared across a brokerage's internal roster of agents, each of whom creates a separate portal entry. A spot check of listings in the Arjan neighbourhood near Dubai Miracle Garden in early June 2026 by one proptech compliance firm found 34 distinct portal entries resolving to 19 actual available units — an inflation rate of nearly 80 percent for that micro-sample.

What the Market Is Doing About It

Several proptech startups operating out of Dubai Internet City have been building reverse-image-search pipelines trained specifically on UAE property photography — the particular palette of developer renders, the standardised kitchen finishes common to mid-market towers — to automate duplicate detection at scale. The Dubai Future Foundation's real estate data working group has held at least two workshops in 2026 on standardising listing metadata, though no regulatory deadline for mandatory image-hash submission to DLD has been announced publicly.

For buyers navigating this environment, the practical calculus is simple: cross-reference any listing against the DLD's own REST transaction database, which is publicly searchable and records actual sales rather than advertised inventory. If a listing has been active for more than 90 days without a price change in a submarket where average time-on-market is under 45 days — figures consistent with recent data from the Marina and Downtown Dubai corridors — it is almost certainly a stale duplicate or a deliberately parked listing held open for lead generation. Agents operating under the RERA Certified Broker programme are required to remove or update listings within 15 days of a transaction closing. Reporting non-compliant listings directly to the DLD's smart complaint portal remains the most direct mechanism available to buyers who suspect they are looking at ghost inventory.
