What helps, what holds it back, and the evidence behind each score.

40/100Overall research score
Property research scores across eight dimensionsEach axis runs from zero at the centre to 100 at the outside. Missing evidence is not zero and is not joined across the chart.

79% evidence coverage · 5 of 7 applicable dimensions scored

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

Strongest supported dimension: Connectivity (60). Lowest supported dimension: Resale demand (0).

Value20% weight50/100Latest recorded sale reference of S$301,000 is in line with the S$301,000 comparable central price, based on 13 compatible sales in the last 5 years. Matching the comparable central price gives 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 2 compatible sales in the last 5 years (60 calendar months including the current month), with the price reference in that window. Historical reference and private asking-price scenarios are labelled separately.

  • Comparable sales: 13 in the selected size/type cohort (2024-12) Source
  • Latest recorded sale reference: S$301,000 (2024-12) Source
  • Source checked: HDB resale transactions (2026-09-07) Source
Resale demand15% weight0/100Resales were recorded in 0 of 12 completed months, with 0 matching sales in that year. 13 matching resales in the last 5 years meet the 2-transaction minimum. That gives 0/12 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 2 single-unit resales in the selected property segment in the last 5 years, and source coverage of all 12 completed months. Only activity in those 12 months contributes points. 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; 0 sales; 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; 2025-10 to 2026-08 (2026-08) Source
Connectivity15% weight60/100The nearest recorded operational MRT is Mattar MRT, approximately 858 m away. Being more than 800 m but within 1,200 m earns 60 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: Mattar MRT (2026-09-07) Source
Everyday living10% weight · UnscoredWe 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% weight41/100The selected records indicate approximately 40.8 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 records in the last 5 years; year-only starts are approximate.

  • Recorded tenure: 99-year leasehold (2024-12) Source
URA growth catalysts10% weight · UnscoredNo 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 applicableThis 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. Transaction minimum: 2 compatible sales in the last 5 years. Overall also 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-1.2.

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.
