How to read this grade. RPS is a relative comparison of seven scored factors, not a valuation, return forecast or buy recommendation.
TRIBE's 2026 back-test found the composite separated later resale returns less clearly than Historical Performance alone, so the grade should be used to open the factor details, not to close a buying decision. Read the evidence →

- Score out of 10

- Highest score among 434 resale condos in District 15
- 157th
Solid, middle-of-the-pack project. Standout strengths: schools, MRT access. Key weaknesses: rental yield, future transformation.
Project's Historical Performance25%6/10
Avg Ann. of +4.01% — but from only 4 resale sales in the last 10 years, too thin a sample to read capital appreciation reliably, so the score is discounted toward the cohort average.
The district median is 6.5/10.
Primary School Effect20%10/10
4 primary schools within 1km (nearest: Tao Nan School at 0.40km). Exceptional school catchment — strong appeal for families with young children.
The district median is 8/10.
- Tao Nan School
- CHIJ (Katong) Primary
- Tanjong Katong Primary School
- Haig Girls' School
Within 1km on OneMap's School Query for at least one block, the measure MOE uses for Primary 1. Check your block's postal code on OneMap School Query →
Project Size16%3/10
19 units — very small project; niche product with thin resale market.
The district median is 3/10.
MRT Proximity13%10/10
150 m from Marine Parade MRT (TE26) — direct, walk-in MRT access. Strong commuter appeal.
The district median is 8/10.
Rental Yield10%2/10
Rental yield of 2.25% — weak income return.
The district median is 4/10.
Tenure10%10/10
Freehold tenure — no lease decay concerns, preserves long-term value.
The district median is 10/10.
Future Transformation6%0/10
No URA Masterplan transformation zone or upcoming MRT station within 3.5km of this project — minimal forward-looking infrastructure tailwind.
The district median is 1/10.

Medians are across the 434 scored resale projects in District 15 (East Coast, Marine Parade). “Effect on score” is the factor's weighted difference from that median, so the column sums (to within rounding) to the gap between Sea Avenue Mansions and a median-profile project (6.21). “Scores above” is the share of those projects this one out-scores on the factor. Weights and bands are on the methodology page.

Sea Avenue Mansions Notes
How these numbers are worked out
- Grade B places Sea Avenue Mansions in a relative band under the current seven-factor formula. RPS is a relative comparison of seven scored factors, not a valuation, return forecast or buy recommendation. TRIBE's 2026 back-test found the composite separated later resale returns less clearly than Historical Performance alone, so the grade should be used to open the factor details, not to close a buying decision. Two units can still be very different buys: the asking price, stack, floor, facing and condition decide the outcome.
- PSF against the district: $1,711 psf at Sea Avenue Mansions against $1,852 psf across District 15, medians over 12 months.
- MRT distance is a straight line on the map; the walking route is longer.
- Prices: aggregates of URA REALIS resale caveats, data to October 2026 (Nov 2025 – Oct 2026). A specific unit's value depends on floor, size, facing and condition.
- By unit type: a price range is shown from three sales up; with two, the figure is the median. Unit types with one sale, and sales with no bedroom count on record, are left out.
- Past transactions: every resale and sub-sale caveat lodged with URA from Nov 2021 to Oct 2026, newest first; a unit is its storey and stack (#07-18). Typing a unit or a stack lists its sales across the whole span. Profit is the sale price less the seller's own purchase price as the caveats pair them, before stamp duties, fees and loan interest; the gain a year is compounded and shown from one year held. The trend line is the median from two sales up per month, quarter or half-year, the district line from ten. 10Y appears once the dataset runs that far back.
- Factor bars: the black mark on each bar is the district median.
- Score: seven weighted factors. Methodology published.
What the score cannot tell you
- RPS scores the project, not a unit. Floor, stack, facing, renovation and the asking price are outside the score. In the 12 months to October 2026, the 2 resale caveats at Sea Avenue Mansions ranged from $1,660 psf to $1,762 psf: that spread is unit-level variation the score cannot see.
- Recent price evidence is thin: 2 resale caveats in the 12 months to October 2026. The Historical Performance factor (6/10) rests on the 10-year record, not on this window.
- Historical Performance is a percentile among projects of similar vintage (completed around 1997, within a year or so, widened when the cohort is small). A high score is strong for its age group, not against the whole market.
- The nearest MRT is Marine Parade MRT (TE26), 150 m in a straight line. The walking route is usually longer, and bus links are not scored.
- Primary School Effect counts the 4 primary schools within 1 km on OneMap's School Query (the school's land boundary to the block's building outline, the measure MOE uses for P1), weighted by recent P1 ballot demand. A school counts when any block is within 1 km, so confirm your own block's postal code before relying on it.
- Scores updated October 2026; transactions to October 2026. Nothing on this page is a valuation or advice on a specific unit.
- Facing decides a unit's morning or afternoon sun, and it varies stack by stack. See the sun path at Sea Avenue Mansions for any facing, date and time → The hours count direction only; the 3D map draws the shadows of the blocks around it.
