Invest Singapore 2026 District 21 lens
District 21 carries the Bukit Timah address without the CCR price tag. Investors frequently compare D21 to District 10 Bukit Timah and walk away either overpaying for D10 prestige they do not need, or undervaluing D21 green-fringe premiums that hold rent psf above OCR heartland averages. Invest Singapore publishes this hub to frame the difference with numbers, not marketing.
The regional context starts with PSF spread. PropertyNet 2026 estimates place CCR near S$3,208 psf, RCR at S$2,695 psf, and OCR at S$2,154 psf. District 21 sits in the upper OCR band, with Beauty World and Hillview new launches touching S$2,200 to S$2,450 psf and older Dairy Farm resale trading below S$2,200 psf. The gap to D10 CCR is real: at S$3,208 versus S$2,200, investors buying D21 with equity deployed in D10 could have purchased nearly 46 percent more floor area.
Q1 2026 quarter-on-quarter price growth ran OCR at 2.2 percent, RCR at 0.8 percent, and CCR at 0.6 percent. Suburban OCR momentum outpaced prime by nearly four to one on a percentage basis. D21, sitting at the quality upper end of OCR, benefits from that suburban bid while retaining nature-fringe tenant depth that pure heartland estates cannot replicate.

What District 21 covers on the map
URA District 21 runs from Upper Bukit Timah Road corridor south-west through Hillview, Dairy Farm, Cashew, and Beauty World, then curves toward the Clementi Park fringe at the district boundary with D5. The district is bounded on the east by Bukit Timah Nature Reserve and on the north by the Central Catchment Area, creating a green edge that limits supply and sustains lifestyle premiums.
Sub-areas within D21 carry distinct characters:
| Sub-area | Transport anchor | Character | Typical buyer |
|---|---|---|---|
| Beauty World | Beauty World MRT (DTL) | Mixed-use node, new launches | Family upgraders, DTL commuters |
| Hillview | Hillview MRT (DTL) | Low-density residential, landed fringe | Owner-occupiers, long-hold landlords |
| Dairy Farm | Cashew MRT (DTL) | Nature park edge, low-rise condos | Green lifestyle buyers, school families |
| Cashew | Cashew MRT (DTL) | Quieter DTL belt, mid-density mix | Compact-unit investors, NUS spillover |
| Clementi Park fringe | Bus to Clementi EWL | D5 boundary, OCR-RCR transition | Family tenants cross-shopping D5 |
| Upper Bukit Timah Road | King Albert Park MRT (DTL) | D10 border fringe, older stock | CCR cross-shop buyers, freehold seekers |
The King Albert Park MRT station sits on the D10 and D21 boundary, creating a shared transport node. D21 projects within a short walk of King Albert Park MRT market themselves against D10 entry PSF while delivering OCR price levels. Investors should verify which URA district the project falls in, since D10 carries CCR classification with different financing and ABSD considerations in some contexts.
PSF benchmarks and 2026 price behaviour
District 21 trades between the OCR benchmark of S$2,154 psf and the lower RCR fringe near S$2,695 psf. The spread within D21 itself is wide because Beauty World new launches, older Dairy Farm resale towers, and Hillview landed-fringe condos all sit in the same URA district but serve different buyer profiles.
Beauty World and Hillview new launch resale from 2023 to 2025 reached S$2,200 to S$2,500 psf. The Reserve Residences at Beauty World (TOP 2027) was transacted at headline psf figures above S$2,300 for selected stacks. Older leasehold stock at Dairy Farm and Cashew from the 1990s can be found at S$1,900 to S$2,100 psf with remaining tenure a key variable.
| Price tier | Indicative PSF band | Examples | Notes |
|---|---|---|---|
| New launch DTL belt | S$2,200 to S$2,500 | Beauty World, Hillview MRT fringe | Location and floor dominate pricing |
| Mid-tier resale | S$2,000 to S$2,200 | 2000s condos, Cashew corridor | Check remaining lease and MCST sinkfund |
| Older resale freehold | S$2,100 to S$2,400 | Upper Bukit Timah freehold clusters | Freehold premium; capex on dated units |
| Budget resale leasehold | S$1,800 to S$2,000 | Late 1990s Dairy Farm towers | Sub-60-year tenure requires financing check |
Q1 2026 OCR price growth of 2.2 percent q/q runs ahead of CCR and RCR by a wide margin. D21 is not a peripheral OCR district; it shares the Bukit Timah green corridor with D10 CCR, so its upper PSF band has historically tracked closer to RCR than to OCR heartland. Buyers comparing Dunearn House against D10 CCR entry stock should verify each project’s URA district before assuming comparable holding dynamics.
Rental yield: D21 OCR nature-fringe bands
D21 yields sit above D10 CCR but below pure heartland OCR because nature-reserve adjacency and DTL school tenancy provide above-average rent psf relative to purchase PSF. The differential between D21 and D10 is the core investor argument: at S$2,200 psf versus S$3,208 psf in D10, the same rent psf generates a yield gap of roughly 130 basis points.
URA median rent for OCR sits near S$4.80 psf, but D21 family units in the school-belt corridor and units near Hillview and Cashew MRT sustain S$5.00 to S$5.30 psf on renovated stock. That positions D21 gross yields in the 2.8 to 3.8 percent band depending on purchase price, unit format, and school proximity.
| Scenario | Purchase PSF | Monthly rent psf | Unit size (sq ft) | Monthly rent | Gross yield |
|---|---|---|---|---|---|
| New launch Beauty World | S$2,350 | S$5.10 | 850 | S$4,335 | 2.64% |
| Hillview resale renovated | S$2,100 | S$5.20 | 900 | S$4,680 | 2.97% |
| Dairy Farm 3-bed school belt | S$1,950 | S$5.30 | 1,100 | S$5,830 | 3.58% |
| Cashew older leasehold | S$1,900 | S$4.90 | 800 | S$3,920 | 2.90% |
Brochure quotes above 4.0 percent gross in D21 usually assume below-median purchase psf, above-median rent psf, and no vacancy. Underwrite net yield using the Singapore rental yield guide after stripping MCST, property tax, agent renewals, and realistic vacancy of four to six weeks.
D21 landlords accept yield below heartland OCR peaks in exchange for:
- Family tenant depth tied to Methodist Girls’ School, Pei Hwa Presbyterian Primary, and National Junior College catchments
- Lower void frequency on three-bedroom units where school choice drives two-year lease renewals
- Nature reserve lifestyle that supports premium rent psf on renovated stock above typical OCR averages
- Long-hold owner-occupier bid at exit that limits forced discounting in soft markets
For districts where gross bands consistently reach 3.8 to 4.5 percent, compare the highest rental yield districts map.
Tenant profile and unit-type fit
District 21 attracts two distinct tenant pools that rarely overlap and should not be underwritten interchangeably.
Family school-belt tenants: Three-bedroom and four-bedroom units near Methodist Girls’ School (Blackmore Drive), Pei Hwa Presbyterian Primary, and CHIJ Our Lady of Good Counsel attract Singapore resident families and some expatriate families on education-driven leases. These tenants prioritise gate proximity over MRT walk time and typically sign two-year agreements with renewal options. Rent psf for renovated three-bedroom units in genuine school-belt proximity can reach S$5.20 to S$5.50 psf, above district median.
DTL professional tenants: Two-bedroom compact units near Beauty World, Hillview, and Cashew MRT appeal to professionals commuting to the CBD via Downtown Line, and to NUS and one-north workers commuting to District 5 Clementi fringe employment nodes. These tenants prioritise train walk time, unit condition, and gym or pool amenities. Rent psf for compact two-bedrooms near DTL stations typically runs S$4.80 to S$5.20 psf.
Nature lifestyle buyers: A smaller premium pool of expatriate and local professionals seeks green-fringe lifestyle at Dairy Farm, Hillview, and Cashew with easy access to Bukit Timah Nature Reserve trails. These tenants accept above-average rent for low-density surroundings, but the pool is narrow compared with the school belt or DTL professional segment.
Investors should match unit format to the dominant tenant pool in each sub-area. A compact one-bedroom at Dairy Farm competes poorly against compact two-bedrooms near Beauty World MRT for DTL professionals. A large four-bedroom near Hillview serves owner-occupiers better than short-term investors targeting high turnover.
Connectivity: DTL and the Beauty World corridor
The Downtown Line (DTL) defines D21 transport. Beauty World MRT (DT5), King Albert Park MRT (DT6, shared with D10 fringe), Hillview MRT (DT3), and Cashew MRT (DT2) form a contiguous corridor through the district. DTL provides direct service to Bugis, Promenade, Bayfront, and Expo without line changes, covering CBD financial district and Changi corridor workplaces in roughly 30 to 40 minutes from inner D21 stations.
| Station | CBD journey estimate | Key employment nodes served |
|---|---|---|
| Beauty World (DT5) | 30 to 35 min | CBD, Marina Bay, Bugis |
| King Albert Park (DT6) | 32 to 37 min | CBD, Marina Bay |
| Hillview (DT3) | 35 to 42 min | CBD, Expo via line change |
| Cashew (DT2) | 40 to 48 min | CBD (longer end of DTL) |
The Cross Island Line (CRL) is planned to serve the Bukit Timah corridor but station locations and opening dates remain subject to government announcement. Until CRL opens, discount any CRL transport premium on D21 stock the same way OCR investors discount unopened MRT links on unconfirmed parcels.
Bus density along Upper Bukit Timah Road complements DTL for tenants in Dairy Farm and deeper Hillview who are more than 12 minutes walk from a DTL station. Tenants prioritising train walk time under seven minutes are served by Beauty World and Cashew; tenants in landed-fringe Hillview rely on bus or car and accept that trade-off for lower-density living.
Nature reserve premium and green lifestyle anchors
Bukit Timah Nature Reserve and Dairy Farm Nature Park form the eastern and northern boundaries of D21. This supply constraint is structural: greenery buffers cannot be rezoned for residential development, so the view and access premium for condos backing the reserve is not eroded by new project supply the way a city-fringe view can be blocked by the next tower.
Green lifestyle anchors in D21 include:
- Bukit Timah Nature Reserve trail access from Upper Bukit Timah Road and Dairy Farm entrances, popular with both resident tenants and weekend visitors
- Dairy Farm Nature Park boardwalk and Wallace Trail, offering low-density forest character unmatched in OCR
- Rail Corridor (former KTM railway line) running through the western edge of D21, providing cycling and walking connectivity to the Southern Ridges and one-north
- Clementi Park fringe green buffer at the D5 boundary, supporting low-rise condo character in the transition zone
These amenities support above-average OCR rent psf for nature-adjacent units and sustain owner-occupier bid at exit. However, they do not substitute for MRT walk time in yield underwriting. A Dairy Farm condo with park views but a 20-minute walk from Cashew MRT rents at a lower psf than an equivalently sized unit a six-minute walk from Beauty World MRT.
Stock mix: freehold, leasehold, and new launches
D21 stock spans a wide age and tenure range. Freehold clusters exist along Upper Bukit Timah Road near the King Albert Park MRT fringe and at select Hillview addresses. Leasehold towers from the 1990s and early 2000s are common across Dairy Farm and Cashew. New launch leasehold on government land sale sites at Beauty World and Hillview MRT has replenished modern stock since 2020.
| Tenure type | Typical PSF | Rent psf tendency | Investor angle |
|---|---|---|---|
| Freehold resale, dated | S$2,100 to S$2,400 | S$4.80 to S$5.20 | Long-hold wealth storage; capex on renovation |
| 99-year resale, 2000s | S$1,900 to S$2,150 | S$4.60 to S$5.00 | Better gross yield; check remaining tenure |
| New leasehold launch | S$2,200 to S$2,500 | TBD until rental history | Refer to Dunearn House for current PSF |
| Late 1990s sub-70-year | S$1,750 to S$2,000 | S$4.40 to S$4.80 | Financing risk; bank haircuts on remaining lease |
Freehold premium at D21 PSF levels is less compressed than in D10 CCR because the absolute dollar gap between freehold and 99-year is smaller. A freehold unit at S$2,300 psf versus a leasehold at S$2,050 psf represents a 12 percent spread: meaningful but not prohibitive for long-hold owners targeting yield rather than pure capital preservation.
New leasehold launches near Beauty World and Hillview MRT anchor resale comparables for the district. Dunearn House represents current D21 new-launch exposure; benchmark its indicative PSF against recent URA caveats for the same sub-area and bedroom type before committing to a launch price.
D21 vs D10 Bukit Timah CCR: same name, very different yield math
The Bukit Timah address appears in both D21 and D10, and this creates persistent confusion on property portals. The distinctions are structural and cannot be smoothed over with marketing language.
| Factor | D21 Upper Bukit Timah (OCR) | D10 Bukit Timah (CCR) |
|---|---|---|
| URA region | OCR | CCR |
| Indicative PSF 2026 | S$2,100 to S$2,450 | S$2,800 to S$3,600 |
| Gross yield band | 2.8 to 3.8 percent | 1.5 to 2.5 percent |
| Tenant dominant | Family school belt and DTL professionals | Expatriate family, embassy fringe, school belt |
| Nature access | Direct Bukit Timah Nature Reserve access | Bukit Timah Road fringe, less immediate park access |
| ABSD calculation | Same 60 percent for foreigners | Same 60 percent for foreigners |
| School belt character | Methodist Girls’, Pei Hwa, NJC | UWCSEA Dover, Tanglin Trust, ACS International |
| New launch benchmark | Dunearn House | Amberwood at Holland |
D21 does not replicate D10 school-belt prestige at a lower price. The two districts serve different tenant profiles and different exit markets. D21 OCR buyers at S$2,200 psf can achieve 2.8 to 3.8 percent gross versus D10 CCR at 1.5 to 2.5 percent, but they give up CCR classification, landed-adjacent Tanglin fringe, and embassy corridor tenant depth.
Cross-read District 10 Bukit Timah when school belt and CCR prestige are the primary filters. Buy D21 when yield spread and nature-reserve lifestyle outweigh the prestige label.
D21 vs D5 Clementi RCR: which fringe wins on yield
District 5 Clementi is RCR at PSF near S$2,695 psf with gross yields of 3.0 to 3.8 percent on NUS, one-north, and family school-belt tenancy. D21 is OCR at S$2,100 to S$2,450 psf with gross yields of 2.8 to 3.8 percent on DTL professional and school-family tenancy.
| Factor | D21 Upper Bukit Timah (OCR) | D5 Clementi (RCR) |
|---|---|---|
| PSF band | S$2,100 to S$2,450 | S$2,300 to S$3,000 |
| Gross yield | 2.8 to 3.8 percent | 3.0 to 3.8 percent |
| Employment node access | CBD via DTL 30 to 40 min | NUS, one-north, CBD via EWL |
| Tenant anchor | School belt and DTL professionals | NUS faculty and students, one-north tech |
| Nature lifestyle | Bukit Timah and Dairy Farm reserves | West Coast Park, limited nature reserve |
| School belt | Methodist Girls’, Pei Hwa, NJC | Nan Hua Primary, School of Science, NUS |
D5 Clementi at median RCR PSF offers fractionally better gross yield than D21 new launch stock when NUS proximity fills compact two-bedrooms efficiently. D21 beats D5 on green lifestyle character and delivers comparable yield on older resale stock priced below the OCR median.
The deciding factor is tenant profile match: if your unit targets NUS faculty, one-north tech professionals, or EWL commuters, D5 Clementi is the more natural home. If your unit targets DTL CBD commuters, Bukit Timah school families, or green-lifestyle tenants, D21 fits better.
Foreign buyer and ABSD considerations
Foreign nationals face 60 percent ABSD on residential purchases in Singapore, including D21. At D21 PSF of S$2,200 for a 900 sq ft unit (S$1,980,000), the stamp duty exceeds S$1,188,000. Total acquisition cost including legal fees, BSD, and ABSD approaches S$1,400,000 on top of purchase price.
D21 offers no structural ABSD relief compared with D10 CCR. The same 60 percent applies. The difference is entry ticket: a foreign buyer needing to amortise 60 percent ABSD over 12 to 15 years of yield and appreciation faces a smaller absolute hole at D21 PSF than at D10 CCR, but the percentage burden is identical.
Foreign buyers in D21 should structure around:
- US or Swiss FTA relief on first residential property, which removes the 60 percent layer entirely
- Corporate entity structures advised by Singapore tax counsel where the ABSD rate may differ
- Hold horizons of 12 or more years allowing rent income to partially offset duty in discounted cash flow models
- Exit plan targeting another HNW buyer who values nature reserve lifestyle, rather than HDB upgrader mass demand
Read the Singapore property investment guide for TDSR and financing notes. Non-resident foreign buyers should confirm bank lending terms, as some lenders haircut OCR properties differently from CCR when assessing loan-to-value.
Worked example: 850 sq ft two-bedroom at Hillview DTL
Assume purchase at S$2,200 psf on 850 sq ft (S$1,870,000), rent at S$5.10 psf on renovated DTL-proximate unit, maintenance S$520 monthly, property tax S$6,200 annually, agent renewal S$2,200 annualised, vacancy 5 percent.
| Line item | Amount |
|---|---|
| Purchase price | S$1,870,000 |
| Monthly rent | S$4,335 |
| Annual gross rent | S$52,020 |
| Gross yield on price | 2.78 percent |
| Maintenance (annual) | S$6,240 |
| Property tax | S$6,200 |
| Agent and vacancy | S$4,802 |
| Net operating income | S$34,778 |
| Net yield on price | approx 1.86 percent |
Add S$60,000 to S$80,000 renovation on dated stock to reach tenant-ready standard. First-year net yield drops below 1.5 percent before recovering to the 1.8 to 2.0 percent range in years two to five. This example shows that D21 at new launch PSF near S$2,200 does not deliver high net yield: it delivers meaningful yield spread over D10 CCR at roughly 50 percent lower entry ticket with similar net percentage.
For a school-belt three-bedroom at Dairy Farm older resale purchased at S$1,950 psf and rented at S$5.30 psf, the gross yield reaches 3.26 percent and net yield after operating costs approaches 2.2 to 2.5 percent. That scenario better illustrates the D21 value proposition: older resale in the school-belt corridor, not new launch at Beauty World top-floor pricing.
Pros and cons of District 21 property
Pros
- OCR pricing between S$2,100 and S$2,450 psf delivers genuine yield spread over D10 CCR at S$3,208 psf
- DTL corridor at Beauty World, Hillview, and Cashew MRT provides direct CBD access without line changes
- Bukit Timah Nature Reserve and Dairy Farm Nature Park create structural supply constraints that protect green premium
- Methodist Girls’ School, Pei Hwa Presbyterian Primary, and NJC school belt sustains family tenant demand with above-average lease renewal rates
- Q1 2026 OCR price growth of 2.2 percent q/q led all Singapore regions, supporting near-term capital appreciation thesis
- Mix of freehold and leasehold stock gives long-hold buyers tenure optionality at different PSF entry points
Cons
- Nature reserve fringe commands above-OCR-average PSF that compresses gross yield versus pure heartland OCR districts
- DTL journey times to CBD of 30 to 40 minutes lag CCR and D5 Clementi EWL at 20 to 30 minutes
- Older Dairy Farm and Cashew leasehold stock from the 1990s carries remaining-tenure risk and MCST capex cycles
- School-belt family units above 1,200 sq ft face void periods of six to ten weeks when tenants depart at school-year end
- D21 lacks the international-school expatriate tenant depth of D10 CCR, limiting rent resilience when local school enrolments fluctuate
Investor scenarios: who should buy D21
DTL yield upgrader from CCR: Buyers who cross-shopped D10 CCR, rejected 1.5 to 2.5 percent gross yield, and want the same school-belt Bukit Timah corridor at OCR PSF with 2.8 to 3.8 percent gross.
Family owner-occupiers prioritising nature and schools: Buyers who value Bukit Timah trail access and Methodist Girls’ or Pei Hwa school catchment at prices 30 to 40 percent below D10 equivalent floor area.
Long-hold local upgraders from HDB: HDB residents in Bukit Batok, Hillview, or Cashew HDB estates who want private condo within the same neighbourhood at OCR PSF.
Who should skip D21: Yield-focused buyers who need 4.0 percent gross to service leverage should start with the highest rental yield districts map and compare heartland OCR districts. Short-hold flippers targeting sub-three-year exits face SSD (Seller Stamp Duty) on residential property purchased after 2022. Foreigners at 60 percent ABSD without FTA relief and under 12-year hold horizon should restructure acquisition before any OTP.
Buyer scenarios decision matrix
| Scenario | Unit type | PSF band | Hold | Verdict |
|---|---|---|---|---|
| A DTL professional landlord | 2-bed, near DTL | S$2,100 to S$2,300 | 8 to 12 yr | Accept 2.6 to 3.2 percent net; DTL tenant depth solid |
| B School-belt family landlord | 3-bed, Dairy Farm corridor | S$1,900 to S$2,100 | 12 plus yr | Best D21 yield case at 2.8 to 3.5 percent net |
| C Owner-occupier nature lifestyle | 3 to 4-bed, Hillview | S$2,100 to S$2,400 | 10 plus yr | Strong if nature and school drive decision |
| D New launch buyer | 2 to 3-bed DTL | S$2,200 to S$2,500 | 10 plus yr | Compare Dunearn House vs recent resale caveats |
| E CCR cross-shop | Any D21 | Any | Any | Confirm yield gap vs D10 justifies OCR trade-off |
| F Pure yield seeker | Any | Any | Any | Skip D21 new launch; use highest yield districts |
The D21 value case is clearest in scenarios B and C where older school-belt resale at below-OCR-average PSF meets genuine family demand. Scenario A works but requires DTL walk time under ten minutes and renovated unit condition to sustain S$5.00 psf rent.
Risks specific to Dairy Farm and Upper Bukit Timah stock
Remaining lease concentration: The late 1990s Dairy Farm cluster holds multiple projects with remaining leases below 75 years. Financing haircuts from banks at sub-70-year tenure reduce buyer pool at exit. Underwrite exit liquidity against local mortgage availability, not just current transact PSF.
School enrolment volatility: Methodist Girls’ School and Pei Hwa Presbyterian Primary balloting phases reward residential proximity. If catchment boundaries shift or school ranking perception changes, rent psf premiums tied to specific addresses can soften faster than the broader D21 market.
New launch supply at Beauty World: The Beauty World regeneration under URA’s Long-Term Plan includes additional government land sale sites that could add new launch supply into the DTL corridor over the next five to eight years. Monitor GLS tender results annually; fresh launches at similar PSF compress older resale exit timing.
Nature reserve trail access does not protect against void: Green lifestyle premiums attract a narrow tenant pool. Landlords pricing above district median for nature views need to budget eight to twelve week void periods if renovated school-belt units at lower rent psf are available nearby.
Hillview landed fringe illusion: Several Hillview condos market themselves as landed-adjacent or green-fringe premium. That premium is real for owner-occupiers but does not always translate to rent psf above DTL-proximate stock near Beauty World MRT. Walk the route from the condo gate to the MRT before assuming lifestyle premium equals yield premium.
Schools and catchment zones in D21
School proximity is D21’s most consistent rent-resilience factor. Understanding actual catchment distance matters more than brochure labels.
| School | Type | D21 proximity | Tenant impact |
|---|---|---|---|
| Methodist Girls’ School | MOE secondary (IP) | Blackmore Drive, central D21 | Premium rent on 3-bed in 1 km zone |
| Pei Hwa Presbyterian Primary | MOE primary | Bukit Timah Road fringe | Strong family tenant demand for Phase 2A and 1 km |
| National Junior College | MOE JC | Clementi Road fringe | Limited direct catchment impact on rent psf |
| CHIJ Our Lady of Good Counsel | MOE primary and secondary | Bishan fringe; less direct D21 impact | Modest spillover only |
| Dulwich College Singapore | International | Brickworks Road, D21 fringe | Small expatriate family pool; do not overstate |
Units marketed as school-belt but requiring a 15-minute bus ride at morning peak rarely achieve premium family rent psf. Invest Singapore underwrites school proximity by measured gate-to-gate commute, not brochure radius circles. Always walk or time the route at 7:30 AM on a school day before assuming catchment commands rent above district median.
International school catchments in D21 are narrower than in D10 CCR. Dulwich College Singapore is proximate but targets a thin expatriate pool. Do not underwrite D21 on D10-style expatriate family tenancy assumptions.
What to verify before you buy in District 21
Pull URA transaction history for your target project and three comparables within 600 metres. Compare median PSF by stack and floor band, not only the lowest historical caveats. D21 PSF variation across floors and stacks in the same tower can exceed S$200 psf for nature-facing versus road-facing units.
Request rental evidence for the same bedroom type over the last four quarters. URA median OCR rent near S$4.80 psf is a regional benchmark; D21 school-belt family units vary S$4.80 to S$5.50 psf and DTL professional two-bedrooms vary S$4.60 to S$5.20 psf.
Inspect MCST financials for upcoming works. Dairy Farm and Cashew leasehold projects from the late 1990s are approaching 30-year building age with associated lift, facade, and plumbing event risk. Special levies erode net yield when the absolute dollar amount is high relative to annual rent income.
Check remaining lease carefully for any 1990s project. Sub-75-year remaining tenure reduces the buyer pool on exit and may trigger bank loan-to-value haircuts on your own financing.
Confirm DTL walk time from gate to station at peak hour. Hillview and Cashew fringe projects listed as near DTL sometimes require 15 to 18 minutes walk. Family tenants accept bus connectivity; DTL professional tenants are sensitive to station walk time under 10 minutes.
Benchmark new launch PSF against Dunearn House current indicative pricing and recent URA caveats for the same sub-area. Showflat prices occasionally incorporate developer marketing premiums that resale caveats do not fully support.
Cross-read District 10 Bukit Timah if school-belt CCR prestige and embassy corridor tenant depth matter more than yield spread, and District 5 Clementi if NUS and one-north employment proximity is a higher priority than green nature reserve lifestyle.
Closing view on District 21 Upper Bukit Timah
District 21 is OCR property with structural green-fringe advantages that lift it above typical suburban pricing. PSF between S$2,100 and S$2,450, gross yields of 2.8 to 3.8 percent, and Q1 2026 OCR price growth of 2.2 percent q/q position D21 as the accessible alternative to D10 CCR for buyers who want the Bukit Timah corridor without the CCR yield compression.
Win in D21 by matching unit format to tenant profile: three-bedroom school-belt resale at older PSF for family landlords, compact two-bedroom DTL-proximate stock for professional investors, and owner-occupier size for nature lifestyle end-users. Underwrite net yield after MCST and vacancy before any OTP. Use Dunearn House as the current launch PSF benchmark, D10 as the prestige comparison floor, and D5 Clementi as the yield-and-employment crosscheck.
Frequently Asked Questions
District 21 suits buyers who want OCR pricing with green-fringe lifestyle and DTL school-belt tenancy. PSF ranges from S$2,100 to S$2,450 across sub-areas, delivering gross yields of 2.8 to 3.8 percent at URA median rent near S$4.80 to S$5.20 psf. Nature reserve adjacency and Methodist Girls' School proximity sustain family demand. It is not a pure yield play like heartland OCR, but it offers a meaningful spread over CCR D10 Bukit Timah.
District 21 covers Upper Bukit Timah Road corridor, Hillview, Dairy Farm, Cashew, Beauty World, and Clementi Park fringe. URA classifies most of D21 in OCR with pockets touching the RCR fringe near Clementi Park and Buona Vista Road. Bukit Timah Nature Reserve and Dairy Farm Nature Park bound the district to the east and north.
D21 trades between the OCR benchmark of S$2,154 and the lower RCR fringe near S$2,695 psf. Beauty World and Hillview new-launch condos reached S$2,200 to S$2,500 psf in 2024 and 2025 resale.
