4 ROOM price history since 1994

Median 4 ROOM sale price each year — the block's most-traded flat type — as transacted and restated to the market level of Q2 2026. The shaded band between the two lines is the market's own rise — the HDB Resale Price Index, not the cost of living. Comparing an old price with a new one without closing that gap overstates how much this block itself gained. Years with fewer than 2 sales carry no point — a median over one sale is that sale's price — but they keep their place on the axis, so the spacing stays true to the calendar and the line simply crosses them.

The median 4 ROOM sale here in 1994 was S$205,500 as transacted — S$761,788 at Q2 2026 market level. The median over the last 24 months is S$800,000.

Restated with the HDB Resale Price Index — our calculation, not a valuation and not a price anyone paid. Every figure on the restated line is measured against the most recently published quarter of the index, so the whole line is redrawn when the next one lands: it lifts when the market rises, and a sale made when the index stood higher than it does today would restate downwards. How this is worked out

By flat type

Sales, size, psf, the record and the date range cover the block's whole recorded history. The second median covers the last 24 months only, and reads — where that flat type has had fewer than 2 sales in the window.

Gross rental yield

Median approved rent over the last 24 months, annualised, over the median resale price of the same flat type over the same window. Gross, before any cost.

About the block

Completion year, flat count and storeys are published by HDB in its Property Information dataset on data.gov.sg — we mirror them unchanged. Est. MOP is our estimate: completion year plus five, because the Minimum Occupation Period runs five years from each household's key collection, which is in no public dataset. Check a specific flat
