This article examines The Island Residences as an investment using publicly available data. It covers the case for the investment honestly, the counterarguments that every serious buyer should understand, and who this development is best suited for. All data is sourced and cited.

The Question Every Buyer Is Really Asking

When a buyer asks whether The Island Residences is a good investment, they are usually asking one of three more specific questions: Will the price hold? Can I rent it? And is the timing right?

The honest answer to all three is: it depends on who you are, what you pay, and how long you hold. This article works through each variable using transaction data, rental records, and historical context – and gives you the framework to answer the question for your own circumstances.

The Investment Case – Four Pillars

Pillar 1 – The Island Address: Singapore’s Most Structurally Scarce Residential Position

The Island Residences sits on Keppel Island – possibly Singapore’s only private island condominium address outside Sentosa. The island spans 5.3 hectares. It cannot be expanded, rezoned for higher density, or replicated. This is not a marketing claim. It is a geographic fact.

In the world’s great cities, island addresses command premiums that persist through market cycles: Monaco’s Le Rocher, New York’s Roosevelt Island, London’s Docklands. Each carries the same logic – water on all sides, city within reach, and a scarcity that money cannot manufacture. Keppel Island is Singapore’s version of this. And unlike those other addresses, it sits just 8 to 10 minutes from Shenton Way via the Ayer Rajah Expressway.

For investors, geographic scarcity is the most reliable long-term value driver. Supply is the most predictable variable in Singapore property. When supply is structurally capped – not just currently limited, but permanently limited by geography – the pricing floor tends to hold even through softer cycles. Read the full analysis of why Keppel Island is possibly Singapore’s only private island condo address outside Sentosa.

Pillar 2 – Supply Scarcity: 84 Units and the Arithmetic of Re-Sale Competition

The Island Residences will have approximately 84 residences. Compare this with the established Keppel Bay precinct:

Development	Units	Re-Sale Pool vs Island Residences
Caribbean at Keppel Bay	969	11.5x larger
Reflections at Keppel Bay	1,129	13.4x larger
Corals at Keppel Bay	366	4.4x larger
The Reef at King’s Dock	429	5.1x larger
The Island Residences	84	The smallest in the precinct

With 84 units, The Island Residences will never see sellers competing heavily against each other for buyers’ attention. For a deeper look at why unit count is the most underrated investment variable in Singapore property, read why 84 units beats 800 every time. In a development of 1,000+ units, five or ten available re-sale units can sit on the market simultaneously and depress pricing through visible supply. At 84 units, available re-sale stock is almost always thin. Thin re-sale supply structurally supports pricing resilience over time.

The Reef at King’s Dock, the most recent new launch in the precinct developed by Keppel Land, launched in January 2021 at an average of S$2,330 psf and currently trades between S$2,212 and S$3,230 psf on the resale market – a development of 429 units has held its value well. An 84-unit development, by comparison, has five times the structural scarcity advantage. You can review full Keppel Bay PSF benchmarks on the price list page.

Pillar 3 – Greater Southern Waterfront: Singapore’s Most Consequential Urban Transformation

The Greater Southern Waterfront (GSW) spans 2,000 hectares of Singapore’s southern coastline – six times the size of Marina Bay and twice the size of Punggol New Town. It is Singapore’s largest urban renewal initiative since Marina Bay itself, and the Keppel segment is its most advanced. For a complete guide, read The Greater Southern Waterfront Explained – What Property Buyers Need to Know in 2026.

The first private residential Government Land Sales (GLS) plot from the former Keppel Golf Course was awarded on 4 November 2025. The winner was Kingsford Huray Development at S$918.3 million, equivalent to a land rate of approximately S$1,326 psf per plot ratio. This site alone will yield approximately 745 new private homes. The wider former Keppel Club site is expected to yield around 9,000 new homes in total – approximately 6,000 public housing units and 3,000 private apartments.

Concurrently, HarbourFront Centre will close in the second half of 2026 for redevelopment by Mapletree Investments. It will reopen in the first half of 2031 as a 33-storey mixed-use development with 26 floors of Grade A offices, curated retail, and a 13,000 sqm elevated waterfront park.

The Island Residences benefits from this transformation as a neighbouring catalyst rather than a construction site. This is the optimal investment position: an established address, with transformation uplift incoming from an adjacent area, without the disruption of being inside the construction zone.

Pillar 4 – The MNC Tenant Pool: A Grade A Office Catchment Unlike Any Other Singapore Waterfront Address

Within 3 to 8 minutes of Keppel Island, there are over 4 million sq ft of Grade A and Grade A-equivalent office space housing some of the world’s most recognisable corporations:

Office Building	Distance	Notable Tenants
Keppel Bay Tower (1 HarbourFront Ave)	~3 min drive	378,000 sqft. Singapore’s first Zero Energy commercial building (BCA Green Mark Platinum Zero Energy).
Bank of America Merrill Lynch HarbourFront (2 HarbourFront Place)	~3 min drive	215,963 sqft. Bank of America global support centre for private banking – one of only three such centres worldwide (alongside the US and UK).
HarbourFront Towers 1 and 2	~4 min drive	Twin 18-storey Grade A towers adjacent to HarbourFront MRT.
Mapletree Business City (Pasir Panjang Road)	~6-8 min drive	~2.9 million sqft. Google Asia Pacific, Deutsche Bank, Samsung Asia, Pfizer, Credit Agricole, Motorola Solutions, IATA.
PSA Building (Alexandra)	~8 min drive	40-storey. PSA International headquarters (world’s second-largest port operator).

The senior professionals employed at these organisations represent precisely the demographic that has historically driven rental demand in the Keppel Bay precinct – executive-level expatriates on multi-year company leases, seeking a prestigious waterfront address within commuting distance of their workplace.

The Counterarguments – What Every Serious Buyer Should Understand

A balanced analysis requires engaging honestly with the arguments against as well as for. The following are the most substantive objections to The Island Residences as an investment.

Counterargument 1 – 99-Year Leasehold Tenure

The Island Residences is a 99-year leasehold development. All comparable Keppel Bay developments – Caribbean, Reflections, Corals, and The Reef – are also 99-year leasehold. Leasehold is standard for Singapore waterfront new launches and does not represent a disadvantage relative to comparables. However, buyers who strongly prefer freehold tenure should note that freehold waterfront options in Singapore are extremely limited and typically priced at a significant premium.

The practical implication of leasehold for investment: lease decay becomes a pricing headwind only as the lease falls significantly below 60 years, which for The Island Residences would not occur until the 2080s. For any buyer with a 10 to 20 year investment horizon, lease decay is not a material consideration.

Counterargument 2 – ABSD for Foreign Buyers and Entities

Foreign buyers currently pay 60% ABSD on any Singapore residential property purchase. Entities and trusts pay 65%. These are substantial additional costs that fundamentally affect the total investment equation for non-citizen buyers. For a complete worked breakdown, read the Complete ABSD Guide for Foreigner Buyers 2026. On a S$5 million unit, a foreign buyer pays an additional S$3 million in ABSD before BSD. This is not a reason not to buy – many foreign buyers assess the total cost and still find the investment case compelling – but it must be factored into every financial model. For a full breakdown by buyer profile, see the stamp duty guide on the price list page. Singapore Citizens purchasing their first property pay zero ABSD.

Counterargument 3 – The Greater Southern Waterfront is a Long-Term Story

The GSW is a multi-decade transformation project. The first residential GLS site was awarded in November 2025, with completion expected in the early 2030s. The broader vision for Tanjong Pagar Terminal and other GSW segments will play out over 20 to 30 years. Buyers who expect short-term price uplift from the GSW alone are likely to be disappointed. This is a long-term investment thesis, not a 2 to 3 year flip.

Counterargument 4 – Price Not Yet Confirmed

The official price list for The Island Residences has not been released at the time of writing. Buyers cannot fully assess the investment case without knowing the entry price. The PSF benchmarks from comparable developments above provide context, but the actual pricing may be above or below expectations. All investment modelling must be revisited once official pricing is confirmed. Register for the price list here to receive it before the public launch.

Counterargument 5 – Understanding the Reflections at Keppel Bay Context

A serious investor considering The Island Residences will almost certainly encounter data showing that Reflections at Keppel Bay – the most visible comparable in the precinct – recorded 29 unprofitable resale transactions in 2025, with some losses exceeding S$1 million. Understanding why this happened is essential to assessing whether the same risk applies to The Island Residences.

Reflections was launched in 2007 and sold primarily between 2007 and 2013. This was the period before Singapore’s Additional Buyer’s Stamp Duty existed. ABSD was not introduced until December 8, 2011. Before that date, foreigners buying Singapore residential property paid zero additional stamp duty – the same as Singapore Citizens. At the time, foreign buyers and corporate entities accounted for a third to half of purchases in the high-end Singapore condo market.

According to EdgeProp records, 17.7% of Reflections at Keppel Bay buyers were foreigners, and a further 7.4% were companies – a combined 25.1% of the total buyer pool purchasing without any ABSD surcharge. Many of these buyers paid at or near the 2007-2013 peak prices, ranging up to S$2,800 psf for premium units, in a market unconstrained by the cooling measures now firmly in place.

When ABSD was introduced and subsequently raised five times, the foreign buyer segment that had supported peak pricing at Reflections effectively collapsed. By 2024, foreigners accounted for just 1% of Singapore condo purchases. Buyers who overpaid at the pre-ABSD peak found themselves selling into a market now dominated by local buyers at different effective price levels.

Reflections 29 unprofitable transactions in 2025 – PropertyNoob (propertynoob.com, March 2026), sourced from EdgeProp Research.

Why this context matters for The Island Residences buyers: The Island Residences is being purchased in 2026 – after all five rounds of ABSD increases, in a market where foreign demand has already been priced out. The comparable PSF baseline of S$2,212 to S$3,230 psf for The Reef at King’s Dock reflects current 2026 market conditions, not a pre-cooling-measures peak. Buyers today are entering at a market level that already reflects the post-ABSD reality.

Furthermore, even Reflections – which has seen resale losses for buyers who overpaid at the 2007-2013 peak – currently delivers rental yields of approximately 3.75%, with 3-bedroom units renting for S$8,500 to S$9,400 per month and 4-bedroom units ranging from S$12,500 to S$25,000 per month. For investors who purchased at reasonable entry prices and held through the cycle, rental income has materially offset paper losses. The waterfront rental demand in Keppel Bay, driven by the MNC employer base described above, has proven durable through multiple property cycles.

Who Is The Island Residences Best Suited For?

Profile 1 – The Own-Stay Luxury Buyer (Singapore Citizen or PR)

The strongest value proposition is for the Singapore Citizen or Permanent Resident purchasing their first or second property for own occupation. Zero or low ABSD, a unique island address, 8 to 10 minutes from the CBD, and a lifestyle – 6 parks, 9km of trails, world-class marinas, golf clubs, waterfront dining – that genuinely has no equal in Singapore. The investment case is secondary to the lifestyle case for this buyer. Book a private viewing to experience the development in person.

Profile 2 – The Singapore Investor (Citizen or PR)

For the Singapore investor purchasing a second or third property, the investment case depends primarily on entry price and rental yield. At 0% ABSD on a first property (or 20%/30% ABSD on second/third), the total acquisition cost is manageable compared to comparable new launches. The boutique 84-unit pool, the island address premium, and the MNC tenant catchment all support the investment thesis. Rental demand in Keppel Bay is well-established and documented. The key variable is entry PSF – register for the price list to assess the investment at the actual entry point.

Profile 3 – The Foreign Investor

At 60% ABSD, the foreign investor is paying roughly S$3 million additional on a S$5 million unit. The investment case at this cost base requires a longer hold, a more compelling rental yield, or a specific view on Singapore’s political and economic stability as a safe haven for capital. Some high-net-worth foreign buyers view the ABSD as the price of access to Singapore’s stable property market and strong rule of law, and assess returns over a 20 to 30 year horizon accordingly. For this buyer, The Island Residences’ unique island address and boutique scale are particularly relevant – they are buying something genuinely irreplaceable in Southeast Asia. Foreign buyers in this category should model their investment with independent financial and legal advice. See the full stamp duty breakdown here.

Conclusion

The Island Residences has a well-grounded investment case across four measurable pillars: island address scarcity that is geographically permanent, supply scarcity at 84 units, GSW transformation uplift as a long-term tailwind, and an MNC employer catchment that supports durable rental demand. The Reflections at Keppel Bay resale losses, properly understood, reflect a specific historical context – pre-ABSD foreign buying at peak prices – that does not apply to buyers purchasing in 2026 after all cooling measures have been in place for over a decade.

The counterarguments are real: 99-year leasehold, ABSD for foreign buyers, a GSW timeline measured in decades, and an official price not yet confirmed. None of these make The Island Residences a bad investment. They make it an investment that requires clear-eyed modelling, realistic return expectations, and a holding horizon appropriate to the asset.

For Singapore Citizens purchasing their first property or investors with a 15-year-plus horizon, the case is compelling. HDB upgraders considering this move should read the HDB Upgrader’s Guide to Keppel Bay for a full financial planning walkthrough. For foreign buyers, the case depends heavily on entry price and holding horizon. For everyone, the starting point is knowing the price – which is available to registered buyers before the public launch. Register for a private viewing or request the price list directly.
