Key takeaways
- THE WADI, launched on 21 September 2026 on Yas Island (Abu Dhabi), represents AED 6 billion spread across 3,950 homes, a hotel, a marina, and retail and leisure space. The developer is Cosmo Developments, a joint venture between Flag Holding Group and Reportage Group.
- The sales pitch rests on the off-plan launch price, on an island where buildable land is running short.
- Rental demand on Yas Island depends mostly on tourism (Ferrari World, Yas Marina Circuit, Etihad Arena), not white-collar employment. That exposes yields to seasonality.
- On tax, Abu Dhabi matches Dubai: 0% on rental income and capital gains. The real gap sits in rental yield and resale market depth, where Dubai keeps the edge over a new off-plan market like Yas Island.
- For a French-speaking investor chasing a comparable net yield, the trade-off favours already-liquid Dubai waterfront zones over a bet on an emerging tourist island in Abu Dhabi.
What exactly does THE WADI include?
THE WADI is a mixed-use project worth AED 6 billion, roughly EUR 1.45 billion at the dollar-pegged AED/EUR rate. It includes 3,950 residential units, a hotel, a marina, and retail and leisure space. It launched on 21 September 2026 on Yas Island, Abu Dhabi.
The developer, Cosmo Developments, is a joint venture between Flag Holding Group and Reportage Group, two high-volume players well established in the UAE. Reportage Group in particular built its reputation on serial deliveries in Dubai and Ras Al Khaimah, rather than on low-volume signature projects.
Yas Island is a 25 km² island east of Abu Dhabi, known for Ferrari World, Yas Waterworld and the Formula 1 circuit. It sits about ten minutes from Zayed International Airport. That's a genuine logistical advantage. But the island remains primarily a tourist destination, not a business hub or permanent residential centre comparable to Dubai.
AED 6bn (~EUR 1.45bn)THE WADI budget · Khaleej Times, 21 Sept. 2026The mixed waterfront positioning means THE WADI's rental value will hinge heavily on the delivery timeline for the marina and hotel. That's a pattern close to what we see at Dubai Maritime City, where yields stay tied to the completion of surrounding infrastructure.
Why this launch is happening now
THE WADI didn't appear out of nowhere. Abu Dhabi has been rolling out waterfront launches since 2024, led first by Aldar on Yas Island and Saadiyat. Cosmo Developments, a joint venture between Flag Holding Group and Reportage Group, is joining a momentum already in place rather than creating it.
Cosmo Developments is a joint venture between Flag Holding Group and Reportage Group, two players already present in Abu Dhabi's residential market.
The real shift is Yas Island's status itself. The island is moving from a leisure destination built around parks and hotels to a fully-fledged residential district. That repositioning justifies a 3,950-unit project on buildable waterfront land that has grown scarce. Land scarcity, more than proven rental demand, explains the launch price.
A volume of 3,950 units isn't trivial. Delivered all at once, it will weigh on local rental supply and could compress rents on the island during the absorption period. The main watch point remains direct competition with other Aldar phases already marketed on Yas, which will capture part of the same target buyer.
What tourism delivers, and what it doesn't guarantee
Yas Island's tourist traffic supports short-stay demand, not automatically long-term residential value. A theme park generates overnight stays, not 12-month leases. That's the nuance many off-plan buyers underestimate on this type of leisure-focused island.
Yas Island or Dubai: where to place AED 1M in 2026?
On a ticket of AED 1 million, the trade-off comes down to three factors: yield, liquidity and market depth. On all three, Dubai wins.
One point must go to Abu Dhabi. On certain waterfront pockets like Yas Island, the entry price per square metre often runs lower than in Dubai, with fewer competing projects nearby. That's a real argument for a buyer sensitive to entry cost.
But on yield, the gap favours Dubai. Gross yields observed there range between 5% and 8% depending on the district, above averages seen in Abu Dhabi.
5-8% by districtDubai gross yield 2026 · Level8, DLD-observedDubai also concentrates most of the UAE's transaction volume, which shortens resale timelines. Districts like Dubai Marina, JVC and Business Bay have long rental histories, documented by the Dubai Land Department. That depth of data reassures lenders and resale buyers alike, an advantage the still-young Yas Island doesn't have.
| Criteria | Yas Island (Abu Dhabi) | Dubai |
|---|---|---|
| Entry price per sqm | Often lower | Higher in mature zones |
| Observed gross yield | Below Dubai average | 5-8% |
| Liquidity / volume | Lower | Dominant in the UAE |
| Documented rental history | Limited (recent zone) | Long, DLD-backed |
| Taxation | 0% on rent and capital gains | 0% on rent and capital gains |
| Currency | AED, USD-pegged | AED, USD-pegged |
Taxation doesn't separate the two emirates: 0% tax on rental income and capital gains applies across the UAE. The dirham stays pegged to the dollar at 3.6725, per the UAE Central Bank. THE WADI can make sense as portfolio diversification. For a core holding, Dubai remains the better-documented, more liquid choice.
How to secure an off-plan purchase at this stage
A freshly announced launch, with no delivery track record, calls for a strict checklist before any signature. Six checkpoints protect the capital committed.
Verify registration and escrow. In Abu Dhabi, the project must be registered with the Abu Dhabi Real Estate Centre (ADREC), the local equivalent of Dubai's RERA. Buyer funds must flow through a dedicated escrow account, released to the developer based on construction progress. Without a verifiable registration number, no payment should go out.
Demand a phase-by-phase timeline. An overall masterplan delivery date says nothing about the specific building you're buying. Ask for the schedule of the relevant phase, with interim milestones and contractual penalties for delays.
Read the payment plan line by line. Deposit at signing, instalments tied to construction progress, balance at handover: every step should be quantified, with late-payment penalties clearly stated.
Model the net yield, not the gross one. Service charges, rental management fees, seasonal vacancy tied to Yas Island's tourism: these costs significantly erode the yield shown in the brochure. Our net yield calculator exists exactly for this. It factors in these costs before comparing two deals.
Compare against the same ticket in Dubai. An equivalent budget invested in a Dubai launch typically delivers a higher gross yield, between 5-8%Dubai gross yield · Level8, 2026 market data, against a tighter range in Abu Dhabi. That's precisely the kind of trade-off we frame for clients across our projects, zone by zone and developer by developer.
Plan the exit before you enter. Market depth determines future liquidity. An investor looking to resell quickly will find more counterparties in Dubai, where the 48-hour buy-back solution illustrates that active liquidity. It's a mechanism structurally harder to replicate in a narrower market like Yas Island.
What this means for a French-speaking investor
THE WADI is a project to watch, not one to sign blindly. Cosmo Developments hasn't yet published a final price grid, nor a firm delivery date for the marina. A serious investor waits for both before putting down a deposit.
The purchase can be made remotely, from France, Belgium, Switzerland, Canada or Israel. UAE developers have largely digitised the process: online reservation, remote KYC, SWIFT transfer. So it isn't a logistical hurdle that should decide the matter, but the net yield gap.
On tax and wealth structuring, Yas Island and Dubai share the same fundamentals:
, and a dollar-pegged dirham that removes currency risk. The AED 2M10-year Golden Visa · u.ae threshold remains the shared benchmark across both markets for long-term residency.no tax on rental income or capital gains anywhere in the United Arab Emirates
Our recommendation: build the core of the portfolio in Dubai, for the gross yield (5-8%, against a tighter range expected on Yas Island) and for secondary market liquidity. Abu Dhabi can then serve as a complement, a waterfront diversification play, once THE WADI's price grid is known. To build that core, our Dubai projects already cover comparable waterfront zones, such as Dubai Maritime City or Dubai Islands.

FAQ
What is THE WADI's total budget and unit count?
THE WADI represents an investment of AED 6 billion, roughly EUR 1.45 billion at the dollar-pegged AED/EUR rate. The project includes 3,950 residential units, a hotel, a marina and retail and leisure space, launched on 21 September 2026 on Yas Island.
Who is Cosmo Developments, the developer behind THE WADI?
Cosmo Developments is a joint venture between Flag Holding Group and Reportage Group, two players already established in the UAE residential market, notably in Dubai and Ras Al Khaimah for Reportage Group.
Does Abu Dhabi's tax treatment differ from Dubai's for a foreign investor?
No, taxation is identical across both emirates: 0% tax on rental income and on property capital gains. The gap between Yas Island and Dubai lies in observed rental yield and resale market depth, not in taxation.
What gross yield can you expect on Yas Island compared to Dubai?
Gross yields observed in Dubai range between 5% and 8% depending on the district, above averages seen in Abu Dhabi. Yas Island remains a young residential market, still dependent on tourist seasonality linked to Ferrari World and the Yas Marina Circuit.
Why is market liquidity lower on Yas Island than in Dubai?
Dubai concentrates most of the UAE's transaction volume, with long rental histories documented by the Dubai Land Department across mature districts like Dubai Marina, JVC and Business Bay. Yas Island, still in a residential repositioning phase, lacks that data history, which reassures lenders and resale buyers.
Should a French-speaking buyer favour Yas Island for a lower entry ticket?
The entry price per square metre can be lower in certain Yas Island pockets, a real argument for a constrained budget. But for a comparable net yield and a faster exit, the trade-off favours already-liquid Dubai waterfront zones — precisely the kind of analysis we frame through our net yield calculator.
