Property Upside score
What helps, what holds it back, and the evidence behind each score.
90% evidence coverage · 6 of 7 applicable dimensions scored
The outer ring is 100. Gaps mean a dimension is unscored.
Strongest supported dimension: Connectivity (100). Lowest supported dimension: Resale demand (42).
Value20% weight50/100Latest recorded sale reference of S$417,500 is 0.1% below the S$418,000 comparable central price, based on 13 compatible sales. The price difference is small enough that the score rounds to the 50-point midpoint. This is a historical comparison, not a valuation or forecast.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 Historical reference and private asking-price scenarios are labelled separately.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% weight42/100Resales were recorded in 5 of 12 completed months, with 5 matching sales. That gives 5/12 of the available points: more months with activity raise the score, while gaps lower it. This reflects consistency of recorded sales, not how quickly your home would sell.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.
- Recorded resale activity: 2025-09 to 2026-08; selected type and tenure (2026-08) Source
Rental appeal10% weight50/100Rentals were recorded in 6 of 12 completed months, based on 8 matching flat-type records. More months with recorded activity earn a higher score, so regular activity helps and gaps bring it down. These are owner-declared records; gaps do not prove vacancy and the score does not measure rental returns.View evidence and calculation
How it is assessed. 100 × months with recorded rentals / 12 completed calendar months, minimum 5 contracts and full source coverage. Uses the same flat type. Activity continuity, not occupancy, investment return or project-size-normalised demand.
- Recorded HDB rentals: 8 records; 2025-09 to 2026-05 (2026-05) Source
Connectivity15% weight100/100The nearest recorded operational MRT is Mayflower MRT, approximately 326 m away. Being within 400 m earns the highest band, 100 points. 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: Mayflower 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% weight50/100The selected records indicate approximately 49.9 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.

URA growth catalysts10% weight75/100Cross Island Line phase 1 is the strongest matched catalyst. Construction is under way, starting at 85 points under our delivery-stage rules. The property is approximately 894 m from the Bright Hill MRT reference. Being farther from that reference subtracts 10 points, giving 75/100. This measures proximity and delivery stage, not future price growth. Timing and project details are in the evidence below.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
- Cross Island Line phase 1: Under construction; 2030 (LTA target). Approx. 894 m straight-line to Bright Hill MRT reference. An additional MRT line is being built at this existing interchange, broadening east-west travel options. Construction disruption and changes to completion dates remain possible. Distance uses the existing station reference, not the future entrance. (2026-09-06) 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.

Official historical records are supplied by HDB/data.gov.sg and URA. Dates retain source precision. Price per square foot uses each record’s stated area basis; land area, strata area and multi-unit sales are labelled and may not be directly comparable. Original fields, quality flags and source provenance remain available on every row.
