Editorial policy

PropertyInsider.sg exists to give Singapore property buyers access to the kind of research that is typically available only to professionals — rigorous market analysis, transparent price methodology, and independently sourced data, presented clearly and updated as the market moves.

We are not a listings portal and we do not carry paid listings, developer advertising, or sponsored coverage. Our editorial content is never influenced by developer marketing budgets or advertising relationships. Separately from this editorial operation, the publisher — Jamus Lee (CEA Reg. No. R065771E, ERA Realty Network Pte Ltd) — provides licensed property advisory services, and readers are welcome to contact him for personalised advice through the Contact an Advisor forms across the site. That advisory relationship is fully disclosed in the related interests section below and has no influence over what we publish. This separation is the foundation of everything on this site.

Our goal is to become the most trusted independent source for Singapore new launch research and property analysis — a site that buyers, investors, journalists, and researchers can rely on for honest data and clear-eyed analysis.

Every article and analysis published on PropertyInsider.sg is researched from primary sources. We do not rewrite press releases. We do not reproduce developer marketing copy. We do not rely on secondary aggregations when primary data is available.

For new launch research, our standard process is:

We cite every data point we publish. The following are our primary data sources and how we use them:

Source	Data type	How we use it
URA REALIS	Transaction caveats, resale prices, rental contracts	Comparable launch PSF analysis, resale price benchmarks, rental yield projections
URA GLS website	Confirmed and reserve list sites, tender results, land bid prices	Price estimation inputs (land cost psf ppr), GLS pipeline tracking
URA Master Plan	Zoning, plot ratios, development control parameters	Neighbourhood analysis, development potential assessments
HDB website	Resale flat prices, BTO launches, town data	HDB upgrader catchment analysis, MOP timelines, resale price benchmarks
EdgeProp Singapore	Project-level transaction history, psf trends	Cross-referencing URA data, historical price charts
BCA Building Cost Index	Construction cost benchmarks by building type	Construction cost inputs for the price estimation model
MAS	SORA rates, TDSR/MSR guidelines, financing policy	Interest rate context, affordability analysis, financing guides
Developer announcements	Official project details, price lists, floor plans	Project page updates once official information is released

Estimated launch prices are the primary feature that differentiates PropertyInsider.sg from other Singapore property sites. We publish estimated launch prices systematically, with fully disclosed methodology, before developers announce. This is our most important editorial commitment and our most important transparency obligation.

Our price estimation follows a five-step model:

Every estimated launch price page discloses all inputs, assumptions, and the date they were last reviewed. When a developer releases an official price list, we update the page within 48 hours and log the change.

PropertyInsider.sg is produced by the PropertyInsider editorial team — a group of Singapore property researchers and analysts. We maintain the publication under a shared editorial identity rather than individual bylines, consistent with our position as an independent research publication rather than a personal blog.

Our analytical work draws on the following disciplines: Singapore property market research, URA and HDB data analysis, mortgage and financing analysis, property valuation methodology, and investigative research practice.

Stale content is a form of misinformation in property research. Prices change, tenders close, developers are awarded — a page that does not reflect these changes misleads rather than informs. Here is our update schedule by content type:

Every page that changes materially carries an update log at the bottom. The log shows what changed, when, and why — not just a timestamp saying "last updated."

We make mistakes. When we do, we correct them promptly and transparently. We do not quietly edit errors without acknowledgement — that practice undermines the trust a research publication depends on.

This editorial policy was last reviewed on 10 July 2026. It is reviewed annually and updated whenever our practices or standards change materially. The version history is available on request.

Full transparency about who publishes this site and what other interests they hold is fundamental to our credibility. This section discloses all material relationships.

Advisory services — Contact an Advisor

The publisher of PropertyInsider.sg, Jamus Lee (CEA Reg. No. R065771E, ERA Realty Network Pte Ltd, Licence No. L3002382K), is a licensed property advisor practising via JamusProperty.com. Readers may — and are expressly permitted under this policy to — contact Jamus for personalised property advisory services, including buying, selling, financing and asset progression planning. The "Contact an Advisor" forms that appear across this site exist for that purpose, and each carries this same disclosure at the point of submission.

Advisory enquiries submitted through those forms are shared with the advisory practice with the reader's explicit consent, and only to respond to the enquiry. The advisory practice operates entirely separately from the editorial research desk: it does not choose what we cover, does not review analysis before publication, and does not alter a verdict — favourable or otherwise. Whether or not a reader ever engages the advisory service has no bearing on the research they can access, all of which remains free.

Project marketing sites

The publisher operates project marketing websites for selected Singapore new launch developments. These are lead capture pages entirely separate from PropertyInsider.sg's editorial operation. They do not fund or influence what we publish.

How conflicts are managed

Where PropertyInsider.sg publishes independent research on a development that also has a corresponding publisher-operated project marketing site, we disclose this within the analysis page itself — specifically in the Key Facts Table, with a note directing readers to this editorial policy for context.

We do not accept payment from developers, agents, or any commercial party for editorial coverage. Project marketing sites listed above do not fund or influence the editorial content published on PropertyInsider.sg. If a project receives unfavourable analysis, that analysis is published without modification regardless of the publisher's other interests in that project.

PropertyInsider.sg does not carry advertising. We do not accept payment from developers, property agencies, mortgage brokers, or any commercial party for editorial coverage, featured placements, or sponsored content.

The site is funded by the publisher's advisory practice at JamusProperty.com. This funding relationship is disclosed in the footer of every page on this site and in the related interests section above. It does not confer any editorial influence over what we publish.

We do not use affiliate links to property listings portals or mortgage comparison platforms. If this policy changes, we will update this page and log the change with a date.

Sections 08 and 09 were added on 6 July 2026; the advisory services disclosure in section 08 was expanded on 10 July 2026 to expressly permit readers to contact Jamus Lee for advisory services. This editorial policy was last reviewed on 10 July 2026 and is reviewed annually or whenever our practices change materially.
