How accurate is this estimate for Sumang Lane?

Half the estimates came closer than this to what the home actually fetched, half missed by more.

What the rent says

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

5.33% gross yield

S$39,600 of rent a year against the estimate above · 0.44 points below flats like it

Homes like this rent for about S$3,300 a month, the middle of 4 approvals in the last year.

Across Singapore these flats yield 5.77%, from 234 blocks. Too few blocks share this flat's remaining lease to measure that separately, so this figure covers every lease length.

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.

Sale prices as filed in caveats.

Where the lease takes this

About 90 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 years85 yearsS$706,751S$780,310S$845,091S$859,871
10 years80 yearsS$663,583S$808,904S$948,789S$982,265

On a flat market the lease alone costs 21% over 20 years. Prices would need to rise about 1.2% 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.
