Property Upside score
Eight dimensions of the evidence for this property.
53% evidence coverage · 3 of 7 applicable dimensions scored
The outer ring is 100. Gaps mean a dimension is unscored.
Strongest supported dimension: Connectivity (100). Lowest supported dimension: Value (9).
Value20% weight9/100
Latest recorded sale reference: S$975,000 against a S$839,000 comparable central price. Historical evidence, not a valuation or forecast.
How it is assessed. 50 + 250 × (comparable central price − assessed price) / comparable central price, bounded 0–100. At least 5 compatible sales and a latest comparable within 12 months. Historical reference and private asking-price scenarios are labelled separately.
Resale demand15% weight · Unscored—
Insufficient current, source-qualified evidence.
How it is assessed. 100 × months with resale activity / 12 completed calendar months, minimum 5 single-unit resales in the selected property segment and full source coverage. Monthly activity consistency is a proxy, not turnover or time-to-sell; no dwelling-count denominator is available.
Rental appeal10% weight · Unscored—
Insufficient current, source-qualified evidence.
How it is assessed. Requires current recorded rental contracts or published project rental medians. Reporting continuity is a proxy; unmatched rent and floor area never produce a yield.
Connectivity15% weight100/100
Serangoon MRT is approximately 285 m away in a straight line.
How it is assessed. Nearest operational MRT straight-line distance: 100 at ≤400 m, 80 at ≤800 m, 60 at ≤1,200 m, 40 at ≤2,000 m, 20 at ≤3,000 m. Beyond covered evidence is unscored; distances are not walking times.

Everyday living10% weight · Unscored—
Insufficient current, source-qualified evidence.
How it is assessed. Average proximity across schools, food/markets, parks and shopping: 100 at ≤500 m, 75 at ≤1,000 m, 50 at ≤2,000 m, 25 at ≤3,000 m. All four categories require sourced coverage; school proximity does not establish admission eligibility.
Tenure resilience15% weight62/100
Approximately 61.5 years remaining as of Sep 2026. Tenure longevity only; no financing or resale guarantee.
How it is assessed. Lease score = 100 × remaining years / 99, bounded 0–100; an explicitly recorded freehold title scores 100. Deduct elapsed time from recorded remaining lease, or use term and commencement year. Median across selected recent records; year-only starts are approximate.
- Recorded tenure: 99-year leasehold (2026-06) Source
URA growth catalysts10% weight · Unscored—
No current, geographically matched growth announcement in the reviewed coverage.
How it is assessed. Highest matched catalyst score, without stacking overlapping announcements. Under-construction interchanges: 90 for a 2028 target, 85 for 2030, 80 for 2032; long-term district plans: 60 for Jurong Lake District, 55 for Greater Southern Waterfront. Subtract 10 beyond 500 m or 20 beyond 1 km. These are editorial proximity/stage points, not predicted returns. Reviewed catalogue covers selected announcements, not every Singapore plan. Reviews expire after 90 days; zoning alone earns no catalyst points.
- Master Plan zoning at the mapped reference point: Residential; gross plot ratio 2.8. (2026-09-06) Source
- Redevelopment evidence boundary: MP2025 zoning is indicative. A legal site boundary and existing gross floor area are required before calculating redevelopment headroom. Check subsequent amendments in URA SPACE. (2025-12-01) Source
En bloc potential5% weight · Not applicable—
Private strata collective-sale scoring does not apply to this property class.
How it is assessed. A score requires verified strata ownership, site boundaries, existing lawful GFA, redevelopment entitlement and costs. Building age or a zoning polygon alone does not establish collective-sale feasibility or probability.
An editorial research indicator, not a price forecast or government rating. Overall requires at least 70% of applicable weight, including value and resale evidence. Compare only within the same property class and coverage profile. As of 2026-09-07 · Method upside-1.0.

How to read this analysis
The comparable range contains the middle 50% of observed prices; it is not a forecast or a confidence interval. Floor, condition, facing and remaining lease can materially change a home’s value. A price below a benchmark is a reason to investigate, not proof of a bargain.
