Property Upside score

Eight dimensions of the evidence for this property.

30% evidence coverage · 2 of 8 applicable dimensions scored

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

Strongest supported dimension: Connectivity (100).

Value20% weight · Unscored—

Insufficient current, source-qualified evidence.

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 Historical reference and private asking-price scenarios are labelled separately.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—

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% weight · Unscored—

Insufficient current, source-qualified evidence.

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% weight100/100

Marine Parade MRT is approximately 266 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.

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% weight100/100

Explicitly recorded freehold tenure. 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.

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.

En bloc potential5% weight · No reviewed activity · Unscored—

No reviewed collective-sale activity in this limited catalogue. This does not establish that no activity exists. Redevelopment feasibility is not established.

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.

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.

How to read the evidence

These figures describe completed historical resales in the available official records. A recorded median is not a valuation or an asking price.

What do the records cover? Straits Mansions has 4 recorded resales from 2022-10 to 2026-02 in the available official data. 2 fall within 2025-10 to 2026-09. Choose a relevant unit size below before assessing a particular home.

These counts show reported rental activity, not occupancy or how quickly your unit will find a tenant. Records can include renewals, and larger developments naturally tend to have more contracts.

Your unit's rentability also depends on asking rent, layout, condition, furnishing and lease restrictions. The recorded size bands below show the rents achieved by broadly similar-sized properties.

Compare neighbouring rental yields

Indicative gross project yield = quarterly median monthly rent per sq ft × 12 ÷ median resale price per sq ft in the same quarter. Rental and sale records concern different units. This mixed-unit project proxy excludes vacancy, costs, financing, condition and unit-specific lease effects.

No neighbouring projects meet the common-period, property-type and sample requirements. No comparison yield has been invented.

The subject has insufficient compatible evidence for a public project-yield benchmark. The optional calculator in the rental yield section is available for personal assumptions.
