Data and Sources Policy Page
Data & Sources Policy
Louis Property Insights helps buyers make clearer, better-informed property decisions through transparent project information, buyer-focused analysis and practical verification guidance.
This Data & Sources Policy explains how information is sourced, assessed, classified, updated and corrected when preparing property reviews, buyer guides and related content. LPI focuses primarily on Kuala Lumpur, with selected project coverage in Penang and Johor Bahru.
Quick Answer
Louis Property Insights uses the most relevant and authoritative available sources for the specific fact being reviewed, including official project documents, developer materials, government or regulatory information, market references and clearly labelled analytical assumptions.
Information is classified as Confirmed, Estimated, Indicative, Proposed, Unverified or No Longer Current so buyers can understand what is known, what may change and what still requires verification.
1. Purpose of This Policy
The purpose of this policy is to explain:
- Where our property information may come from
- How we treat different types of sources
- How we distinguish confirmed facts from estimates or assumptions
- How we handle changing project details
- How buyers should use the information on this website
Louis Property Insights does not aim to replace legal, financial, tax or valuation advice.
Instead, the website provides general property education, buyer analysis and project review content to help buyers ask better questions before making a decision.
This policy explains how information is sourced, classified, updated and corrected. The Property Review Methodology separately explains how LPI analyses projects, assesses buyer suitability and presents strengths, risks and trade-offs.
2. Main Types of Sources We May Use
Depending on the project or topic, Louis Property Insights may refer to several types of information sources.
These may include:
- Official project brochures
- Sales kits
- Floor plans
- Price lists
- Sales packages
- Developer updates
- Official project websites
- Public planning or location information
- Property market listings
- Rental market references
- Government or regulatory sources
- Buyer enquiry materials
- Site visit observations
- Publicly available maps and transport information
- Comparable project references
- Louis Property Insights’ own analysis and interpretation
Not every article uses every source type.
The sources used depend on the project, the information available and the purpose of the content.
3. How Source Authority Is Assessed
Louis Property Insights gives greater weight to the most authoritative, current and relevant source for the specific fact being reviewed. Source authority depends on the type of information being checked.
| Information Type | Sources Generally Given Greater Weight |
|---|---|
| Legal ownership, tenure and contractual matters | Formal legal, statutory or contractual documents |
| Project specifications, layouts and facilities | Latest dated official project documents, approved plans and developer-issued materials |
| Pricing, packages and availability | Latest dated official price lists, written packages and current authorised updates |
| Developer and listed-company information | Official company disclosures, Bursa Malaysia announcements and annual reports |
| Government, planning and market data | Relevant government agencies, regulators, local authorities and official market-data sources |
| Market context and comparisons | Completed transaction data where available, reputable listings and comparable-project references |
| Buyer-facing clarification | Written clarification from relevant authorised parties, clearly identified and dated |
| LPI analysis | Clearly labelled assumptions, scenarios and interpretation based on the available evidence |
This is not a fixed ranking for every situation. A sales kit may be appropriate for a current floor plan, while a statutory document may carry greater authority for tenure or legal ownership, and official market data may be more appropriate for wider market analysis.
Asking prices and rental listings are not the same as completed transaction prices or confirmed rental agreements.
4. How We Classify Project Information
Property information can change over time.
For this reason, Louis Property Insights may classify project details using the following status labels.
Confirmed
“Confirmed” refers to information supported by a reliable, current and relevant source appropriate to the fact being reviewed. The source may be a legal, statutory, contractual, regulatory or official project document.
Examples may include:
- Project name
- Property type
- Location
- Tenure
Project developer or developer entityApproved or current official layout categoriesContractual built-up areaOfficial unit countCurrent dated official price list or package, subject to availability and later updates
Confirmed information is still subject to final legal documents, regulatory approval and the Sale and Purchase Agreement where applicable.
Estimated
“Estimated” refers to information that is currently presented as an estimate and should not be treated as a final guarantee.
Examples may include:
- Estimated completion date
- Estimated maintenance fee
- Estimated holding cost
- Estimated rental range
- Estimated investment return
- Estimated monthly repayment
Estimated information may change due to developer updates, market conditions, final management decisions, financing rates or legal documentation.
Indicative
“Indicative” refers to information used for general reference only.
It may vary by unit, floor, view, package, buyer profile, timing or final confirmation.
Examples may include:
- Indicative price
- Indicative net price
- Indicative package
- Indicative rental assumption
- Indicative furnishing cost
- Indicative yield calculation
Indicative figures should always be checked again before booking or signing any agreement.
Proposed
“Proposed” refers to features, concepts or plans that may still be subject to developer confirmation, final approval, design changes or operational decisions.
Examples may include:
- Proposed facility concepts
- Proposed rooftop concepts
- Proposed commercial components
- Proposed connectivity or access arrangements
- Proposed management models
A proposed feature should not be treated as guaranteed unless confirmed by final approved plans or binding documentation.
Unverified
“Unverified” refers to claims or details that have not yet been sufficiently confirmed by reliable documentation available to Louis Property Insights.
Examples may include:
- Guaranteed view
- Guaranteed short-term rental approval
- Guaranteed covered walkway
- Guaranteed public access to facilities
- Fixed rental income
- Fixed occupancy rate
- Final unit availability
Unverified information should not be relied on as a confirmed fact.
No Longer Current
“No Longer Current” refers to information from older materials that has been replaced, withdrawn or updated by newer and more reliable information.
Examples may include:
Old layout sizes
Outdated floor-plan names
Earlier facility descriptions
Previous prices or packages
Older completion information
Claims no longer used in current materials
Older information may be retained internally for version history, but it should not be presented as the current project position when newer evidence is available.
Louis Property Insights View
The more attractive claim is not automatically selected when information conflicts.
The source with stronger authority, clearer wording and more current project relevance is given greater weight.
5. Project Prices, Packages and Availability
Property prices, discounts, rebates, packages and available units can change frequently.
Any price, package or availability information shown on Louis Property Insights should be treated as time-sensitive and subject to confirmation.
Buyers should always request the latest:
- Price list
- Sales package
- Unit availability
- Furnishing package
- Financing information
- Booking terms
Unless specifically stated otherwise, prices and packages on this website should not be treated as guaranteed, final or permanently available.
6. Layouts, Unit Sizes and Floor Plans
Louis Property Insights aims to describe layouts and unit sizes based on the latest available project materials.
However, floor plan names, unit sizes, bedroom descriptions and layout configurations may differ between earlier and later versions of project documents.
Buyers should verify the latest:
- Floor plan
- Unit type
- Built-up area
- Orientation
- View
- Floor level
- Parcel details
- Car park allocation
- Furnishing list
Where relevant, Louis Property Insights may comment on layout efficiency, buyer suitability and practical use of space.
These comments are analysis-based opinions and should not replace personal inspection or professional advice.

Any rental, Airbnb, yield, return or capital appreciation discussion on Louis Property Insights is provided for general analysis only.
These figures may be based on:
- Comparable market assumptions
- Nearby rental references
- Similar project comparisons
- Estimated operating costs

They are not the historical performance of a future or newly launched project unless explicitly stated and supported by evidence.

- Guaranteed rental income
- Guaranteed occupancy
- Guaranteed Airbnb approval
- Guaranteed capital appreciation
- Guaranteed investment return
Where appropriate, investment analysis may use:
- Conservative scenario
- Base scenario
- Strong scenario
A projection is not a promise. Buyers should review the assumptions, including rent, vacancy, maintenance, furnishing, repairs, financing and competing supply.
Short-term rental eligibility is not determined only by property type or land title.
Buyers should verify:
- Sale and Purchase Agreement
- Development approvals
- House rules
- Future JMB or MC policies
- Local-authority requirements
- Management rules

Comparable projects may be selected based on:
- Location
- Property type
- Tenure
- Completion status
- Unit size
- Pricing level
- Target tenant or buyer profile
- Facilities
- Surrounding supply
- Transport access
A comparable project is not a guarantee that another project will perform the same way.
Each property has different:
- Risks
- Entry price
- Management quality
- Buyer demand
- Completion timing
- Holding costs
- Exit conditions
9. Maps, Distances and Connectivity
Location information may include approximate distances, walking routes, driving access, public transport references and surrounding amenities.
Distances and travel times may vary depending on:
- Exact route
- Traffic
- Weather
- Pedestrian access
- Building entrances
- Construction
- Future infrastructure changes
Where walking distance or connectivity is discussed, buyers should verify the actual route and walking experience personally where possible.
Unless clearly confirmed, Louis Property Insights does not treat proposed connections, covered walkways, future transport access or public access routes as guaranteed.
10. Foreign Buyer, Legal, Tax and Financing Information
Louis Property Insights may publish general content about:
- Foreign buyers

- Correct the relevant fact
- Update the affected section
- Add a clarification
- Update the Last Updated date
- Explain a material change where useful
