63% evidence coverage · 4 of 7 applicable dimensions scored

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

Strongest supported dimension: Connectivity (80). Lowest supported dimension: Rental appeal (42).

Value20% weight47/100

Latest recorded sale reference: S$435,000 against a S$429,000 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 Historical reference and private asking-price scenarios are labelled separately.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: 8 in the selected size/type cohort (2026-06) Source
  • Latest recorded sale reference: S$435,000 (2026-06) 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; 6 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: 6 records; 2026-02 to 2026-08 (2026-08) Source
Connectivity15% weight80/100

Yio Chu Kang MRT is approximately 497 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: Yio Chu Kang 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% weight54/100

Approximately 53.1 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. 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.
