Data Sources & Freshness
WorthIt is built entirely on official, publicly available transaction records. We do not create, estimate, or adjust prices — every figure traces back to a recorded sale.
Where the data comes from
- HDB resale transactions — published by the Housing & Development Board via data.gov.sg, covering completed resale flat sales across all HDB towns.
- Private property transactions — from the Urban Redevelopment Authority (URA), covering condominium, apartment, and executive condominium (EC) sales by district and market segment (CCR / RCR / OCR).
- Location & postal-code lookup — by OneMap Singapore, used to place transactions on the map and power postal-code search.
How often it's updated
WorthIt refreshes its dataset automatically on a regular schedule, re-downloading the latest HDB and URA records. The "Data as of …" note in the site footer always reflects the most recent transaction month currently loaded. Note that the official sources themselves publish with a lag — newly completed sales typically appear about a month after they happen — so the latest available month will usually trail the present month.
Coverage
The dataset spans 370,000+ resale transactions across every HDB town and all 28 Singapore postal districts (D01–D28). Prices are shown net of any furniture, renovation, or cash-over-valuation arrangements that are not part of the recorded transaction value.
Limitations
- WorthIt shows completed transactions only, not current listings or asking prices.
- Figures lag the market by the source publication delay described above.
- Individual prices depend on factors not always captured here — exact unit, condition, and renovation.
- Data is provided "as is" from the official sources; occasional source errors or omissions may carry through.
