Summary

Anyone can look up what an HDB flat sold for. The Housing & Development Board's (HDB) open dataset on data.gov.sg lists resale prices by month of registration from January 2017, is updated daily and held 243,611 transactions on 27 Oct 2026. For private homes, the Urban Redevelopment Authority's (URA) transaction e-Service uses caveats data and data submitted by developers, the Ministry of National Development (MND) said in January 2025.

Price indices answer a different question. URA's and HDB's indices show how prices of comparable homes moved over a quarter, not what a particular home is worth. Both are useful when you set or test a price, as long as you know what each leaves out.

What this means for Singapore buyers and sellers

HDB flats: the resale records

Each record in HDB's dataset gives the month, town, flat type, block, street name, storey range, floor area, flat model, lease commencement date, remaining lease and resale price. HDB leaves out sales between relatives and resales of part shares, because they may not reflect full market prices, and describes the prices as indicative only.

Three details matter when you compare. The month shown is when the resale was registered with HDB, which comes after the price was agreed in the option. Storeys come in ranges, so two flats in the same band can sit several floors apart. And the floor area includes any purchased recess area, space added under HDB upgrading programmes and roof terraces, which can distort a price per square metre.

Private homes: caveats and their gaps

URA's price index draws on caveats lodged with the Singapore Land Registry at the option stage, according to URA's notes on the index. MND said URA's e-Service uses caveats data and data submitted by developers, and that title and ownership information is available on the Integrated Land Information Service (INLIS), managed by the Singapore Land Authority (SLA), regardless of whether a caveat was lodged. A private sale without a caveat can therefore be missing from URA's e-Service but not from the title register.

What the indices measure

A hedonic method adjusts for differences in the homes that sold, such as size and location, so a quarter in which more large or central homes change hands does not by itself push the index up.

The headline figure can hide wide gaps between segments. In Q3 2026, URA's overall index rose 1.4%, while non-landed prices rose 2.3% in the Outside Central Region, 0.3% in the Core Central Region and were unchanged in the Rest of Central Region, URA said on 23 Oct. HDB's resale price index was 202.5 in Q3 2026, down 0.1% from Q2 and its third straight quarterly decline, HDB said. Its flash estimate had been 202.4, down 0.2%.

Flash and final figures

Both agencies publish a flash estimate before the full quarter is counted, then a final figure about three weeks later. URA's flash estimate draws on data up to the middle of the last month, and the final figure can differ, so use the final quarterly numbers when you adjust a price.

Illustration only. ProprKey calculation using the published index levels.

  • A flat that sold for S$600,000 in Q1 2026, when HDB's index stood at 203.4, would be worth about S$598,200 at the Q2 2026 level of 202.8 if it had moved exactly with the index.
  • A S$1.5 million condo in the Outside Central Region that tracked Q3's 2.3% rise in URA's non-landed index for that region would be about S$34,500 higher.

A single home can move more or less than the index. HDB's records give only a storey range and say nothing about facing, view or condition, which is why valuers inspect the home itself.
