What the rent says

What this flat earns against what it costs, set beside what homes like it earn.

6.00% gross yield

S$42,000 of rent a year against the estimate above · 0.12 points above flats like it

Homes like this rent for about S$3,500 a month, the middle of 22 approvals in the last year.

Across Singapore, flats of this type with 50 to 59 years of lease left yield 5.88%, from 39 blocks. This town has too few such blocks to measure on its own.

A yield above the mark means the flat rents well for what it costs, which can point to a keen rental patch or a price the sales alone have not caught up with. Below it, buyers are paying for something a tenant will not, such as the address itself.

Where the lease takes this

About 57 years of the 99-year lease remain. Every figure below lets the lease run down on the decay measured from HDB resales in this market, then applies the price path in that column. The paths are scenarios to choose between, not forecasts.

From nowLease leftPrices flatPrices 2% a yearThis market's record, 3.64% a yearmeasuredPrices 4% a year
5 years52 yearsS$668,719S$738,320S$799,615S$813,599

On a flat market the lease alone costs 20% over 20 years. Prices would need to rise about 1.14% a year to cancel that out.

The measured column repeats what this market did between Q1 2015 and Q2 2026, which was 3.64% a year. Past growth is not a promise of future growth.

Horizons we have not measured are left out rather than guessed at, so a short lease shows fewer rows.

Indicative estimate from comparable caveats. Not a formal valuation.
