DLD vs Bayut vs PropertyFinder: Which Dubai Property Data Source Is Actually Accurate?

Key takeaways: Listing portal medians (Bayut, PropertyFinder, Dubizzle) systematically overstate Dubai property prices because they reflect what sellers want, not what buyers pay. Across communities we sampled, portal medians ran 18–28% above DLD-realized medians. For end-users making purchase decisions, the DLD-realized number is the only honest baseline; portal medians are useful for understanding asking-price psychology but should not be used as a valuation anchor.

What each source actually measures

Three sources, three things measured:

1. Dubai Land Department (DLD). Records every property transaction registered in the Emirate of Dubai. By statute, the purchase price recorded is the price the transaction closed at. This is the realized-transaction truth set. Data is published openly in the DLD's open-data parquet — 1.64M+ transaction records back to 2020.
2. Bayut, PropertyFinder, Dubizzle (listing portals). Aggregate active listings posted by agents and developers. Each listing has an asking price set by the seller. Portal "medians" are typically computed across the active inventory at the time the page was rendered — so they reflect current asking sentiment, not transaction reality.
3. Property Monitor, REIDIN, and similar paid data vendors. Use DLD records as their primary source, augmented with proprietary cleansing and matching against listings. They publish closer to DLD reality but charge enterprise fees.

The wedge in numbers

From our weekly listings snapshot cross-referenced against the same week's DLD-realized medians:

• Median portal asking PSF (city-wide): approximately AED 1,830/sqft
• Median DLD-realized PSF (same period): approximately AED 1,475/sqft
• Wedge: +24% asking premium over realized

That's the headline. The wedge varies by community:

• High-volume mid-tier communities (JVC, Business Bay, Dubai Marina) — wedge around +12–18%. Market is information-efficient; asking prices don't drift far from realized.
• Premium villa communities (Palm Jumeirah, Arabian Ranches villas, Emirates Hills) — wedge often +25–40%. Lower transaction volume, more anchor-pricing freedom for sellers.
• Newer off-plan-heavy communities (Dubai South, The Valley, Damac Lagoons) — wedge often +20–35% but for a different reason: portal listings include both ready and off-plan, and the off-plan asking is the developer-launched headline price, not a transacted price.

Why portals don't fix this

Three structural reasons:

1. Commercial incentive. Portal revenue comes from listing fees. Flagging a listing as "20% above realized" reduces its appeal and creates friction with the agent who placed it. Portals choose not to publish this analysis even though they could compute it.
2. Survivorship in the median. If a listing is overpriced, it stays on the portal longer. If it's fairly priced, it transacts and leaves the portal. So the active inventory at any moment is biased toward the overpriced tail. This is true on every listings portal globally, not just in Dubai.
3. Composition differences. Portal listings skew newer, higher-floor, and "premium-marketed" units within a building. DLD records include the long tail of older, lower-floor, less-marketed transactions. So even with no overpricing, the medians wouldn't match.

When portal medians are useful

Despite the wedge, portal medians have real uses:

• As a sentiment gauge. When the spread between asking and realized widens, that signals seller confidence (or seller stickiness on prices). When it narrows, sellers are accepting the market.
• For active inventory. If you want to know what's currently for sale (not what has sold), the portal is the right source. DLD is backward-looking; portals are forward-looking.
• For agent and developer behaviour. Tracking how individual agents or developers price listings over time can reveal pricing strategies and pipeline dynamics.

How dubuy.ai handles this

Every dubuy.ai community page shows the DLD-realized median as the primary headline number — that's the realised-transaction baseline. We also pull the listing snapshot weekly and compute the asking-vs-DLD wedge for each community, so you can see both numbers together. The wedge is computed at the community + bedroom band level (e.g. "2-bed apartments in Dubai Marina are asking +18% over realized").

For the per-building drill-down (Pro), we go further: building-level DLD medians vs building-level asking, where sample size permits. This is the cleanest valuation comparison available without a custom report.

A note on "indices" published by portals

Bayut, PropertyFinder, and others publish quarterly "market reports" with headline price indices. These reports vary in methodology — some use asking medians, some use weighted averages, some make adjustments for unit mix. We're not saying these reports are wrong; we're saying you should read the methodology footnote to understand what "median" they're reporting before treating it as a valuation benchmark.

The DLD's own quarterly index (Mo'asher) uses transaction prices and is the most defensible single index for Dubai. It's also less prominently published than portal indices — because it doesn't drive listing-portal traffic.

What to do as a buyer

Two rules:

1. For any listing you're considering, look up the DLD-realized median for the same community + bedroom + (ideally) building. Treat that as your valuation anchor.
2. Use portal medians only to gauge how stretched the market is. A wide asking-vs-realized wedge means more room to negotiate. A narrow wedge means sellers are accepting the market and discounts will be smaller.

DLD-realized medians for every Dubai community (1.64M+ source transactions, refreshed weekly) are on Dubuy.ai community pages. The asking-vs-DLD wedge is computed for every community and shown alongside.
