Costa Rhu
Stand at the edge of Rhu Cross on a clear morning and the view does something unusual for Singapore: it stretches. The Kallang Basin shimmers to the west, the Sports Hub dome rises to the north, and to the east a green ribbon of park lines the waterfront all the way toward Bedok. Costa Rhu — 737 units completed in 1998 by Amcol Gardens — occupies one of the few genuinely waterfront addresses in District 15, and that geography has defined both its appeal and its long-running debate for over two decades (as of 2026-05).
The debate is straightforward: you are buying approximately 68 years of remaining 99-year leasehold tenure in exchange for a lifestyle that newer, more expensive condos in the district cannot easily replicate. The average transacted price has hovered between S$1,248 and S$1,858 psf with an average sale price of around S$2.29 million, reflecting a market that values the address but applies a clear lease discount versus freehold peers on Meyer Road less than 2 km away. URA private residential transaction data for the past 12 months shows roughly 148 recorded sales across the estate — healthy velocity for a 28-year-old project, signalling that the lease concern has not frozen liquidity. But the Tanjong Rhu MRT station (TE23) on the Thomson-East Coast Line — which opened Stage 4 in June 2024 — has quietly changed the calculus: a development that once felt car-dependent now offers a direct one-stop connection to Stadium MRT and a 15-minute ride to the CBD. The core question for 2026 buyers is whether that connectivity upgrade is enough to offset the accelerating lease clock. This review answers that question systematically.
Overview & Key Facts
Costa Rhu is a 737-unit waterfront condominium on Rhu Cross in District 15, completed in 1998 on a 99-year lease commencing from 1994. Developed by Amcol Gardens (Tanjong Rhu) Pte Ltd, the development occupies a privileged position along the Kallang Basin waterfront — one of the last stretches of inner-city waterfront living in Singapore’s Rest of Central Region. At 28 years old, Costa Rhu carries the patina of a mature estate: lush landscaping, generously proportioned units built to 1990s standards, and an established community that has weathered multiple property cycles. The development’s name — combining “coast” with the Malay “rhu” (casuarina tree) — signals its identity as a waterfront address, and it delivers on that promise with direct Kallang Basin frontage and Marina Bay skyline views from upper-floor units.
At a trailing twelve-month average of $1,599 psf and an average transaction price of $2,383,292, Costa Rhu trades at a substantial 37–43% discount to competing new launches in the D15 corridor — Grand Dunman at $2,537 psf, Emerald of Katong at $2,640 psf, and The Continuum at $2,790 psf. That discount is not a bargain — it is the market pricing in the lease. Supported by 903 recorded rental transactions and a median rent of $5,500 ($6,007 average), Costa Rhu delivers a gross yield of approximately 3%, underpinned by its enduring popularity with the expatriate community who value the waterfront setting, proximity to the CBD, and access to the Singapore Sports Hub precinct.
Location & Connectivity
Costa Rhu occupies a waterfront position along Rhu Cross in the Tanjong Rhu enclave of District 15, sitting directly on the Kallang Basin — the body of water that connects the Kallang River to Marina Bay. This location delivers one of the most striking urban panoramas available in Singapore residential real estate: upper-floor units facing west and south enjoy sweeping views across the basin to the Marina Bay Sands skyline, the Singapore Flyer, and Gardens by the Bay. It is an inner-city waterfront address that feels distinctly different from the East Coast seafront — more urban, more connected, more central.
The MRT connectivity is solid and has improved significantly with the Thomson-East Coast Line. Tanjong Rhu MRT (TE24) on the TEL is approximately 780 m away, providing direct service to Marina Bay, Orchard, and Woodlands. Nicoll Highway MRT on the Circle Line is just 460 m — a comfortable six-minute walk — connecting to Dhoby Ghaut, Buona Vista, and the full CCL loop. Promenade MRT (CCL/DTL interchange) at 820 m adds Downtown Line connectivity to Bugis, Chinatown, and Bayfront. Having three MRT stations from two different lines within 850 m is a genuine transit advantage that few developments in Singapore can match.
The school catchment is functional rather than exceptional. St Andrew’s Junior School (1.31 km) is the nearest primary school, and School of the Arts (SOTA) at 1.59 km appeals to families with artistically inclined children. Geylang Methodist School (Primary) and Kong Hwa School are also within a reasonable distance. The area is less school-dense than the East Coast or Bukit Timah corridors, but the CBD proximity and international school access (including Chatsworth International and the Canadian International School at Tanjong Katong) serve the expatriate community well.
For drivers, the East Coast Parkway (ECP) on-ramp is immediate, putting Changi Airport within a 15-minute drive and Orchard Road within 10 minutes. The Nicoll Highway arterial provides a direct surface route to the CBD, Marina Bay, and the Civic District — a commute that many residents handle by bicycle along the waterfront promenade in under 20 minutes.

Facilities
Costa Rhu’s facilities reflect the generous land allocation and resort-minded design philosophy of 1990s waterfront developments. The estate occupies a substantial site along the Kallang Basin, and the facilities are laid out to capitalise on the water frontage. The swimming pool complex includes a main pool, a children’s wading pool, and pool-side relaxation areas oriented to face the basin — sunset swims with the Marina Bay skyline as a backdrop are a genuine daily experience, not a marketing photograph. A well-equipped gymnasium, tennis courts, BBQ pits, a children’s playground, and a function room round out the core amenity offering.
The landscaping deserves particular mention. Twenty-eight years of tropical growth have produced mature trees, established hedging, and garden spaces with a density of greenery that no newly launched development can replicate for at least a decade after TOP. Residents consistently cite the “kampung feel” — the sense of living within an established, leafy estate rather than a freshly minted construction site — as one of Costa Rhu’s most valued characteristics.
“The grounds are beautiful — after nearly 30 years, the trees and gardens have grown into something really special. The pool area facing the basin is one of the most scenic in Singapore. Yes, the facilities are not as flashy as new condos, but there is a charm and maturity here that you simply cannot buy new. The management keeps everything well-maintained despite the age.”
— Long-term owner-occupier, three-bedroom (PropertyGuru)
The honest assessment is that the facilities are adequate rather than exceptional by 2027 standards. A 28-year-old gym will not match the equipment and fitout of a 2024 launch, the function room shows its vintage, and the overall amenity count — while perfectly functional — is narrower than what buyers accustomed to sky terraces, co-working lounges, and rooftop infinity pools will expect. What Costa Rhu offers instead is mature landscaping, waterfront positioning, space, and a settled community atmosphere — intangible qualities that carry genuine lifestyle value for the right buyer but will disappoint those shopping by amenity checklist.
Unit Sizes & Layout
Costa Rhu’s unit layouts are a product of the 1990s design era, and that is overwhelmingly a positive for buyers who prioritise living space over marketing gloss. Units are generously proportioned by today’s standards — where a new-launch three-bedroom frequently shrinks below 900 sqft, Costa Rhu’s equivalent units offer substantially more floor area with proper room dimensions, full-sized kitchens with wet-and-dry separation, and balconies large enough to furnish as genuine outdoor living spaces. The average transaction price of $2,383,292 reflects these larger floor plates rather than an elevated PSF — at $1,599 psf, you are buying significantly more square footage per dollar than any competing new launch.
The unit mix spans two-bedroom to four-bedroom configurations, with the larger units commanding premium prices for their water-facing orientations. Units in stacks facing west and south-west enjoy the headline Kallang Basin and Marina Bay views — these are the stacks that drive Costa Rhu’s premium positioning, and they command a meaningful PSF premium over inward-facing and east-facing units. The view differential within Costa Rhu is substantial: a high-floor basin-facing four-bedroom offers one of the most dramatic residential panoramas in Singapore, while a lower-floor, inward-facing two-bedroom delivers a fundamentally different living experience.
The 1990s construction also means ceiling heights, corridor widths, and window proportions that feel more spacious than their modern equivalents. Prospective buyers should physically inspect the specific unit — condition varies significantly depending on whether the previous owner renovated and when. The best-maintained units feel solidly contemporary; the worst-maintained feel dated and will require the full renovation budget. Stack and floor selection matter enormously at Costa Rhu — the gap between a renovated, high-floor, basin-facing unit and an un-renovated, low-floor, inward-facing unit is effectively two different properties at two different price points.
| Bedrooms | Transactions | Avg PSF | Avg Price |

Pricing & Market Position
Based on 148 recorded transactions, sale prices range from $1,230,000 to $4,725,017, averaging $2,399,622 (~$1,580 psf).
Rents range from $2,500 to $16,000 per month across 915 rental transactions. Current rental yield sits at approximately 3.0%.
Price Appreciation
From 2021 to 2026, the average PSF has appreciated by 19.4% (from $1,356 to $1,619 psf).
Neighbourhood Comparison
In the D15 RCR corridor, Costa Rhu ($1,599 psf, 99-year from 1994, ~67 years remaining) occupies the deep-value end of the pricing spectrum — a waterfront location at a lease-discounted PSF. The most direct comparison is Grand Dunman ($2,537 psf, 99-year from 2022, ~95 years remaining), which trades at a 59% premium but offers a full fresh lease, brand-new finishes, Dunman Road MRT integration, and 1,008 units of new-launch scale. For buyers who prioritise lease security and modern specifications, Grand Dunman is the pragmatic D15 choice — but the PSF premium is substantial, and the units will be significantly smaller per dollar.
Emerald of Katong ($2,640 psf, 99-year from 2023) and The Continuum ($2,790 psf, freehold) represent the premium tier of D15 new launches. Both deliver fresh leases (or freehold), modern facilities, and compact efficient layouts — but at 65–74% more per square foot than Costa Rhu. The Continuum’s freehold status makes it the strongest long-term hold in the sub-market, while Emerald of Katong’s Katong Park MRT proximity mirrors Costa Rhu’s own multi-MRT advantage but with 28 more years of lease runway.
Within the mature waterfront segment, The Waterside (freehold, Tanjong Rhu Road) offers similar Kallang Basin views with the critical advantage of freehold tenure — but at a premium PSF and with far fewer units and transaction data points. Pebble Bay (99-year from 1995, ~68 years) is the closest comparable in both age, tenure, and waterfront positioning, trading at a similar PSF range. Choose Costa Rhu over Pebble Bay for larger unit sizes and a more established estate feel; choose Pebble Bay for a smaller, more intimate development. Ultimately, the decision to buy Costa Rhu is a lifestyle-over-lease calculation: you are buying an exceptional daily living experience at a deep PSF discount, funded by accepting that the lease clock is the dominant variable in your exit economics.
| Development | Tenure | TOP | Units | ~Avg PSF |
|---|---|---|---|---|
| COSTA RHU | 99 yrs lease commencing from 1994 | 1998 | 737 | $1,580 |
| GRAND DUNMAN | 99 yrs lease commencing from 2022 | 2023 | 1,008 | $2,537 |
| EMERALD OF KATONG | 99 yrs lease commencing from 2023 | 2024 | 846 | $2,640 |
| THE CONTINUUM | Freehold | 2023 | 816 | $2,790 |
| TEMBUSU GRAND | 99 yrs lease commencing from 2022 | 2023 | 638 | $2,462 |
| AMBER PARK | Freehold | 2021 | 592 | $2,544 |
Lease Decay Analysis
The 99-year lease runs from 1994, meaning approximately 32 years have already been consumed. Roughly 67 years remain — still comfortably within the range where most banks will offer full financing without restrictions.
| Year | Lease remaining | Implication |
|---|---|---|
| 2026 (now) | ~67 years | Full bank financing available |
| 2033 | ~59 years | Approaching 60-year threshold — CPF limits begin for some |
| 2053 | ~39 years | Significant financing restrictions for next buyer |
| 2093 | Expiry | Lease reverts to state |
For a buyer purchasing today with a 10-year horizon (exit around 2036), the lease situation is essentially a non-issue — you’d be selling a property with ~57 years remaining, which is still very bankable. The risk profile changes for longer holds.

What Residents Say
“We have lived at Costa Rhu for 12 years and the view from our unit across the Kallang Basin to Marina Bay is genuinely spectacular — especially at night when the skyline lights up. The grounds are mature and beautifully maintained, and there is a real community here. The Sports Hub next door has transformed the area — we walk to concerts at the Stadium, swim at the Aquatic Centre, and do our groceries at Kallang Wave. The lease is the elephant in the room, but at our age we plan to enjoy this for another 8–10 years and then reassess.”
— Owner-occupier, four-bedroom basin-facing, since 2015 (PropertyGuru)
“I rent out a three-bedroom unit at $5,800 per month to an expat family. The location sells itself — CBD in 10 minutes, three MRT stations nearby, and the waterfront promenade is a daily highlight for tenants. Occupancy has been near-continuous for six years with minimal vacancy. My concern is the exit. With 67 years of lease left and prices not appreciating as fast as newer D15 condos, I am weighing whether to sell within the next 3–5 years before the 60-year mark approaches and buyer sentiment shifts.”
— Investor-owner, three-bedroom, since 2019 (EdgeProp)
“The units are spacious — our three-bedroom is bigger than many new-launch four-bedrooms. We renovated the kitchen and bathrooms for about $60K and the result is a genuinely comfortable home. Nicoll Highway MRT is a six-minute walk and the Circle Line gets me to work in Buona Vista in 25 minutes. The main downside is the lease — we bought knowing that, and we are treating this as a 7–8 year home, not an investment. For pure liveability, it is hard to beat at this price point.”

Waterfront setting with genuine park access. Costa Rhu sits on Rhu Cross, a cul-de-sac that dead-ends at the Tanjong Rhu waterfront promenade. Units facing the Kallang Basin — particularly the higher-floor stacks in Blocks 1 and 3 — command panoramic water views that are structurally protected by the adjacent park corridor. Jogging or cycling to East Coast Park takes under 10 minutes; the waterfront connector loops past the Sports Hub, Marina Barrage, and Gardens by the Bay East without crossing a major road. This liveability edge is genuine and difficult to replicate in a newer D15 launch priced 40–60% above Costa Rhu's current psf (as of 2026-05).
Tanjong Rhu MRT (TE23) — TEL Stage 4 live since June 2024. The Thomson-East Coast Line Stage 4 opening in June 2024 delivered what residents waited 26 years for: Tanjong Rhu MRT is approximately 5 minutes on foot from the main gate. Stadium MRT (TE22) is one stop west, providing interchange access to the Circle Line. The CBD (Marina Bay, Shenton Way) is reachable in approximately 15 minutes. Marine Parade MRT (TE26) and Bayshore are directly east on the same line. The connectivity upgrade is material — it shifts Costa Rhu from a car-dependent weekend retreat into a viable daily-commute address for professionals working in the CBD or Orchard corridor (as of 2026-05).
Large unit formats suited to families and upsizers. Costa Rhu was built in the era before Singapore's unit-size compression. The estate's 2- to 5-bedroom layouts and penthouses average well above 1,000 sq ft, with larger units exceeding 2,000 sq ft. This gives families genuine room to spread out — a living-room-with-dining-room, not a studio-grade open plan. The supply of large-format 99-year leasehold units at this price point in D15 is structurally thin; most new launches in the Amber–Meyer corridor are smaller and significantly more expensive per psf (as of 2026-05).
Established estate with mature facilities and greenery. The 28-year-old estate has mature trees, wide internal roads, and a full complement of recreational facilities including a clubhouse, gym, tennis courts, and a 50-metre pool. Facilities maintenance has been consistent per public feedback. The surrounding Tanjong Rhu neighbourhood is low-rise and relatively quiet — no major construction noise risk in the immediate catchment. Compare this with new launches adjacent to active GLS sites or along the Bayshore corridor still under development (as of 2026-05).
Yield profile relative to price quantum. At the current average transacted psf of approximately S$1,580, gross rental yields on Costa Rhu 2-bedders and 3-bedders track at approximately 3.0–3.5%, which is competitive for D15. The rental yield by district tracker shows D15 averaging 2.6–3.2% across all property types — Costa Rhu's leasehold discount keeps yields above the district median. The buy-to-let calculator using current psf and market rents supports a positive carry position for buyers with moderate leverage (as of 2026-05).
Lease decay — the dominant risk, accelerating from 2026 onward. Costa Rhu's 99-year lease commenced in 1994, leaving approximately 68 years as of 2026. The lease decay effect in Singapore follows the Bala Curve: depreciation is non-linear and accelerates when remaining lease falls below 70 years. Buyers in 2026 are therefore purchasing near an inflection point. CPF Board housing withdrawal rules require that a property's remaining lease covers the youngest buyer to age 95. A 35-year-old buyer today (needing 60 more years of lease) is at the borderline of full CPF usage; a 35-year-old purchasing in 2036, when only 58 years remain, will face pro-ration. This tightening CPF window systematically narrows the buyer pool over the next decade and exerts downward pressure on resale prices, independent of market conditions (as of 2026-05).
CPF and financing cliff at the 60-year threshold. The 60-year remaining-lease threshold — projected to be reached around 2033 — triggers mandatory pro-ration of CPF withdrawals for younger buyers. HDB upgraders, who typically rely heavily on CPF OA funds, will face a disproportionate constraint. Bank loan tenures are also subject to a combined borrower-age-plus-remaining-lease cap of 75 years under MAS residential property loan rules; a 40-year-old buyer in 2033 could face a maximum loan tenure of approximately 25 years rather than the standard 30, effectively raising the monthly debt-service burden. Buyers planning a 10-year hold should model the 2036 exit environment, not today's (as of 2026-05).
En-bloc prospects are structurally limited. Costa Rhu's site geometry — a long, narrow waterfront plot on Rhu Cross — and its 737-unit scale make collective sale consensus among the most difficult to achieve in D15. The minimum 80% threshold under the Land Titles (Strata) Act translates to at least 590 owner sign-offs. For comparison, Mandarin Gardens (1,006 units on a much larger, more rectangular site at Siglap) has attempted three rounds of en-bloc without success; Costa Rhu's smaller footprint per unit of land, combined with waterfront premium owners unwilling to sell at replacement cost, makes a successful collective sale in the foreseeable term unlikely. Do not factor en-bloc upside into a Costa Rhu investment thesis (as of 2026-05).
Upcoming Founders' Memorial station (TE24) — noise and construction risk 2026–2028. LTA has confirmed that Founders' Memorial MRT station — planned between Tanjong Rhu (TE23) and Gardens by the Bay (TE22 equivalent) — is targeted to open in 2028. Construction activity in the waterfront corridor between 2026 and 2028 may affect nearby units. The timeline and specific impact radius have not been fully disclosed, and waterfront units facing west toward the Kallang Basin may experience elevated noise during the construction window (as of 2026-05).
Age-related maintenance and capital expenditure risk. The estate turns 28 in 2026 and will require ongoing expenditure on waterproofing, facade maintenance, pool resurfacing, and M&E system upgrades over the coming decade. While the sinking fund and management fees reflect an established estate, buyers should review the last three years of MCST meeting minutes and sinking-fund balances before committing. Underinvestment in a 28-year-old waterfront building's exterior envelope can result in assessment levies (as of 2026-05).

Costa Rhu is a genuinely good property in the wrong point of its lease cycle — and whether that matters depends entirely on your horizon and buyer profile (as of 2026-05).
For families and HDB upgraders with a 10–12-year hold intent, the combination of waterfront address, TEL connectivity, large unit formats, and a lease-discounted psf relative to new D15 launches makes a compelling case. The window for full CPF usage remains open through the late 2020s, providing a reasonable entry runway. Use the lease decay calculator to model the exit psf at your intended hold year — the Bala Curve numbers are sobering but manageable when priced correctly at entry. Cross-reference with the mortgage calculator to validate affordability at current borrowing rates (as of 2026-05).
For investors seeking capital appreciation, Costa Rhu is a harder case. The structural ceiling imposed by CPF pro-ration (approaching in 2033), the negligible en-bloc probability, and the Bala Curve acceleration mean that psf appreciation above inflation is unlikely over a 7–10-year horizon. Yield-focused buyers who model a clean exit before 2033 have a workable strategy, but must execute the exit — not assume a buyer will pay a premium for a 66-year-old leasehold asset in a normalised market. Compare the District 15 analytics and the The Sea View review (also a mature Tanjong Rhu estate) to calibrate your price discovery. The waterfront is real, the connectivity is now real, but the lease clock is also real — weight all three before signing.
