Research and editorial methodology

1. Sources

Analyses start from official and primary sources wherever they exist: the Housing & Development Board (HDB), the Urban Redevelopment Authority (URA), the Singapore Department of Statistics, the Monetary Authority of Singapore, the Inland Revenue Authority of Singapore, the Land Transport Authority and the Ministry of Education. Every page lists its sources with links, the dataset name, the period covered and the date the data was extracted.

Where a figure comes from a non-official source, such as a developer's published price list or a property portal, that is stated alongside it.

2. Periods and dates

Each analysis shows four dates, so you can judge how current it is:

• Data period: the months or quarters the numbers cover.
• Published: when the page first went live.
• Last updated: the last substantive change.
• Last fact-checked: when the figures, rules and links were last re-checked.

Dated market reports describe a specific month or quarter and are not updated afterwards; they point to the latest report instead. Evergreen guides that depend on policy carry a review date and are re-checked on a schedule.

3. Definitions and method

Each analysis states what is measured (for example, median resale price of 4-room flats, or transaction count by quarter), how figures were grouped or filtered, and any formula used. Raw values are kept as published; rounding is applied only for display.

When comparing leasehold properties of different ages, any lease adjustment is disclosed. If a straight-line adjustment is used for public education, it is labelled as a simplifying method rather than an official valuation standard.

4. Data first, interpretation second

"What the data shows" and "James's interpretation" are always separate, visually distinct sections. The first describes the evidence neutrally. The second is clearly labelled opinion: what James thinks it may mean for buyers, sellers and owners, and under which scenarios.

5. Charts and tables

• Every chart shows its title, metric definition, period, unit, source and extraction date.
• Every chart has a text summary, and where possible the underlying numbers are available as a table.
• Axes start at zero unless a truncated axis is necessary; if so, this is stated on the chart.
• Colour is used consistently: gold marks the data point being discussed, navy and grey give context. Red and green are not used to dramatise price moves.

6. Limitations

Each analysis names its limitations: publication lags, small samples, missing data, and dependence on current policy. A finding for one estate, flat type or period should not be assumed to apply elsewhere.

7. Case studies and client privacy

Case studies describe the process, constraints, evidence and outcome of real work. They are anonymised unless the client has given written consent, and state only results that can be substantiated, with the exact period.

8. Use of AI tools

AI tools may help draft, structure or transform material. They do not replace verification: underlying data, figures, claims and compliance are checked by James before anything is published.

9. Corrections

Material corrections are recorded in a change log at the bottom of the affected page, with the date and what changed. If you spot an error, please get in touch.

10. Claims about James

Statements about James's experience, qualifications or track record appear only when there is a record to support them, in line with the Council for Estate Agencies' guidelines on advertising.
