Below are two PrimeKey Analysis case studies showing how the 8 key pillars correctly predict investment potential.
When evaluating new launch properties, projects with similar entry prices, launch years, and locations often look similar. However, long-term resale data can reveal significant performance gaps.
Using the PrimeKey Analysis (PKA) 8-pillar framework - which evaluates MRT Connectivity, Growth Hotspots, GLS/Enbloc Pipeline, Project Size, Remaining Tenure, Rental Yield, School Effect, and HDB Upgrader (MOP) Demand - it can identify why near-identical launches diverge over time.
The framework can also be applied to resale private residential properties, including executive condominiums.
Case Study 1: Kerrisdale vs Legenda at Joo Chiat
61.8% Outperformance Gap
Launched in 2002 on fresh 99-year leases with near-identical pricing, Kerrisdale and Legenda at Joo Chiat appeared to be direct equivalents. However, over two decades, Kerrisdale achieved +117.3% growth compared to Legenda’s +55.5%.
Overview & Score Comparison
- Kerrisdale (D8): 481 units | Launched 2002 | Entry Price $490 psf
- Legenda at Joo Chiat (D15): 100 units | Launched 2002 | Entry Price $510 psf
| Metric / Audit Period | Kerrisdale | Legenda at Joo Chiat | Difference |
| 10-Year Gross Growth (2002 - 2012) | +117.3% | +55.5% | +61.8% |
| 2002 PrimeKey Score (Backtest) | 35/40 (4.4★) - Investment Grade | 25/40 (3.1★) - Moderate Risk | +10 pts |

8-Pillar Scorecard Breakdown (2026 PrimeKey Score)
| Pillar | Kerrisdale | Legenda at Joo Chiat | Key Divergence Factor |
| MRT Connectivity | ★★★★★ (3-min walk) | ★★☆☆☆ (13-min walk) | Critical Factor: 3-min walk vs. 13-min walk drastically impacts daily convenience & tenant demand. |
| Growth Hotspot | ★★★☆☆ (912m to Kampong Bugis) | ★☆☆☆☆ (2.86km to Paya Lebar Airbase) | Critical Factor: Sub-1km proximity captures infrastructure and rezoning upside. |
| GLS / Enbloc Pipeline | ★★★★★ (7 sites within 2km) | ★★★★★ (5 sites within 2km) | Neutral: Both benefit from active surrounding land sales driving local benchmarks. |
| Project Size | ★★★★★ (481 units) | ★☆☆☆☆ (100 units) | Critical Factor: 481 units ensure high resale liquidity and price discovery vs boutique scale. |
| Remaining Tenure | ★☆☆☆☆ (71 years left) | ★★☆☆☆ (74 years left) | Shared Risk: Both are entering the lease decay/stagnation phase (<75 years remaining). |
| Rental Yield | ★★★★☆ (3.3% RCR) | ★★★★☆ (3.25% RCR) | Neutral: Similar rental returns & cash flow performance. |
| School Effect | ★★★★★ (Hong Wen Primary - Elite) | ★★★★☆ (Tanjong Katong Pri - Popular) | Minor Advantage: Elite-tier school provides stronger long-term family demand. |
| MOP Cluster | ★★★★★ (5,064 upgrader units) | ★★★★★ (4,060 upgrader units) | Neutral: Both have strong pools of nearby HDB upgraders. |
Why the Performance Diverged
Five of the eight pillars were tied or comparable. The 61.8% gap was driven entirely by structural differences fixed at launch:
- Transit Proximity: A 3-minute walk to Farrer Park MRT attracts stronger, more consistent tenant and buyer demand than a more challenging 13-minute walk to Eunos MRT.
- Liquidity & Scale: Kerrisdale's 481 units experienced more transactions for healthy price discovery, whereas Legenda's 100 units suffered thin trading volume and less frequent sales.
- Growth Corridor: Kerrisdale directly benefited from infrastructure development within the Kampong Bugis masterplan boundary.
Case Study 2: Bellewaters vs Bellewoods (Executive Condominiums)
17.3% Outperformance Gap
Both Executive Condominiums (ECs) were built by the same developer and launched in 2014 on identical lease terms. Entry prices were separated by just $18 psf ($796 psf vs $778 psf). However, over 10 years, Bellewaters achieved +82.0% capital growth versus Bellewoods' +64.7%.
Overview & Score Comparison
- Bellewaters (D19, Sengkang): 651 units | Launched 2014 | Entry Price $796 psf
- Bellewoods (D25, Woodlands): 561 units | Launched 2014 | Entry Price $778 psf
| Metric / Audit Period | Bellewaters | Bellewoods | Difference |
| 10-Year Gross Growth (2014 - 2024) | +82.0% ($1,449 psf) | +64.7% ($1,281 psf) | +17.3% |
| 2014 PrimeKey Score (Backtest) | 39/40 (4.9★) - Investment Grade | 32/40 (4.0★) - Investment Grade | +7 pts |
| 2024 PrimeKey Score | 30/40 (3.8★) - Moderate Risk | 31/40 (3.9★) - Investment Grade | -1 pt |
8-Pillar Scorecard Breakdown (2026 Audit)
| Pillar | Bellewaters | Bellewoods | Key Divergence Factor |
| MRT / LRT Connectivity | ★★★★☆ (7-min walk to LRT) | ★★★☆☆ (12-min walk to MRT) | Critical Factor: 7-min walk to Cheng Lim LRT provided superior daily accessibility over a 12-min walk to Admiralty MRT. |
| Growth Hotspot | ★★★☆☆ (934m to Sengkang/Fernvale) | ★★☆☆☆ (1,435m to Woodlands Central) | Critical Factor: Closer proximity to mature regional development. |
| GLS / Enbloc Pipeline | ★☆☆☆☆ (0 sites within 2km) | ★★★★☆ (3 sites within 2km) | Future Catalyst: Bellewoods now holds the advantage with 3 confirmed GLS plots to set new price benchmarks. |
| Project Size | ★★★★★ (651 units) | ★★★★★ (561 units) | Neutral: Both offer excellent scale and high resale liquidity. |
| Remaining Tenure | ★★★★☆ (86 years left) | ★★★★☆ (86 years left) | Neutral: Identical healthy leasehold balance. |
| Rental Yield | ★★★☆☆ (3.4% OCR) | ★★★★☆ (3.5% OCR) | Neutral: Similar yield profiles. |
| School Effect | ★★★★★ (Nan Chiau Pri - Elite) | ★★★★☆ (Admiralty Pri - Popular) | Minor Advantage: Nan Chiau Primary (0.7km) drove premium owner-occupier demand. |
| MOP Cluster | ★★★★★ (38,211 upgrader units) | ★★★★★ (8,609 upgrader units) | Critical Factor: Bellewaters had >4.4x the buyer pool of HDB upgraders within 2km. |
Why Bellewaters Pulled Ahead - and What Changes Next
- The Past 10 Years: Bellewaters won on School Tier (Nan Chiau Primary), LRT Accessibility, and a massive MOP Upgrader Cluster (38,211 HDB units vs 8,609 units), which attracted resale demand.
- The Next 10 Years: The 2026 score inverts slightly (31 vs 30 in favour of Bellewoods). Bellewaters' surrounding GLS pipeline is dry, whereas Bellewoods sits near 3 active GLS sites that will establish higher benchmark pricing in Woodlands.
PrimeKey Analysis Case Studies Key Takeaways
- Unmovable Attributes Drive Outperformance: Project size and MRT/LRT walking distance are fixed at launch. They consistently separate long-term winners from laggards regardless of market cycles.
- Upgrader Clusters Create Price Floors: A large MOP cluster provides continuous local buyer demand that supports resale valuations, even during market slowdowns.
- GLS Pipeline Drives Future Growth, Not Past Performance: Surrounding land sales act as a catalyst for future pricing benchmarks but cannot compensate for weak fundamentals such as poor transit access or project scale.
- Data Over Hype: Long-term capital growth is dictated by systematic demand drivers - not by show flat hype or launch weekend sales figures or momentum.
