5 ROOM price history since 1990
The median 5 ROOM sale here in 1990 was S$95,000 as transacted — S$792,840 at Q2 2026 market level. The median in 2023 is S$579,000.
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

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
