What is the source for the cap rates of office premises in Singapore?

For Singapore office cap rates, the figures come from EdgeProp Singapore’s coverage of the investment and leasing market, which in turn is based on:

- Published office market research and yield data from major real estate consultancies (for example, Core CBD premium and Grade A office yields reported in EdgeProp’s news on CBD office rents and capital values).
- Observed transaction evidence for office buildings reported in EdgeProp’s investment market articles (prices per square foot, achieved yields, and buyer underwriting assumptions).
- Periodic cap rate round‑ups by EdgeProp that summarise prevailing yield ranges by sector (office, retail, industrial) using these research inputs.

If you need the exact data series for a particular cap rate (for example, a specific quarter or sub‑market), you can refer to the relevant EdgeProp Singapore office market and cap rate articles for that period, where the source of the yield numbers is identified in the text or charts.
