The outer ring is 100. Gaps mean a dimension is unscored.

Strongest supported dimension: Connectivity (100). Lowest supported dimension: Value (33).

Value20% weight33/100

Latest recorded sale reference: S$540,000 against a S$505,000 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 Historical reference and private asking-price scenarios are labelled separately.

  • Comparable sales: 12 in the selected size/type cohort (2026-01) Source
  • Latest recorded sale reference: S$540,000 (2026-01) Source
  • Source checked: HDB resale transactions (2026-09-06) Source
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% weight42/100

Recorded rentals in 5 of 12 months; 5 matching flat-type records. Rental activity proxy; owner-declared rents, no unit-matched yield.

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: 5 records; 2025-09 to 2026-08 (2026-08) Source
Connectivity15% weight100/100

Mayflower MRT is approximately 338 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.

  • Nearest sourced MRT: Mayflower MRT (2026-09-06) Source
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% weight55/100

Approximately 54.3 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 (2026-01) Source
URA growth catalysts10% weight65/100

Cross Island Line phase 1: 2030 (LTA target). Matched using Bright Hill MRT as a reference.

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. 1,451 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—

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.

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.
