Property Upside score
What helps, what holds it back, and the evidence behind each score.
32% evidence coverage · 2 of 7 applicable dimensions scored
The outer ring is 100. Gaps mean a dimension is unscored.
Strongest supported dimension: Connectivity (80). Lowest supported dimension: Tenure resilience (61).
Value20% weight · Unscored—Only 4 compatible sales are available in this comparison. At least 5 are needed to score value, so a small sample does not become a good or bad price verdict.View evidence and calculation
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 Historical reference and private asking-price scenarios are labelled separately.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—We cannot yet judge how regularly homes in this segment resell. This needs at least 5 matching resales and a source covering 12 completed months; missing records are not evidence of weak demand.View evidence and calculation
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—We need at least 5 rental records matching this flat type and a current source covering 12 completed months before scoring rental activity. The available evidence does not meet those requirements; this does not mean the flat is hard to rent.View evidence and calculation
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% weight80/100The nearest recorded operational MRT is Khatib MRT, approximately 476 m away. Being more than 400 m but within 800 m earns 80 points; closer stations score higher. This is straight-line distance; the actual walking route may be longer.View evidence and calculation
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.
- Nearest sourced MRT: Khatib MRT (2026-09-06) Source
Everyday living10% weight · Unscored—We do not have current, verified nearby location evidence for shopping. All four everyday amenity categories are needed for a fair score. This does not mean those amenities are absent.View evidence and calculation
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% weight61/100The selected records indicate approximately 60.3 years remaining as of Sep 2026. The score compares that remaining time with a 99-year lease: more years left raise the score, up to 100, while a shorter lease brings it down. Tenure longevity only; no financing or resale guarantee.View evidence and calculation
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 (2025-11) Source
URA growth catalysts10% weight · Unscored—No current, geographically matched growth announcement in the reviewed coverage.View evidence and calculation
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—This metric follows collective-sale activity for private strata developments, so it does not apply to this property type.View evidence and calculation
How it is assessed. Editorial activity rubric: interest 25, committee 40, consent 55, mandate 70, tender 80, negotiation 65; a failed, ended or withdrawn attempt within 3 years scores 20. Latest dated reviewed event supersedes earlier events; repeat attempts add no points. Active stages expire at the earlier of a stated deadline, 90 days after the event, or 90 days after review. Inactive scores also require review within 90 days. Sold projects and older or expired activity are unscored. Exact private residential project identity only. This is an activity indicator, not a probability of sale, valuation or investment return. Redevelopment feasibility is not established: strata ownership, lawful GFA, entitlement, consent, costs and commercial viability require separate verification.
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-1.1.

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.
