Data Sources & Methodology Notice

Last Updated: 23rd January 2026

This Data Sources & Methodology Notice (the “Methodology Notice”) applies to our website located at https://chimney.ai/, mobile applications, tools, and conversational AI features (collectively, the “Platform”). This Platform provides real estate information and user-facing tools, powered by a combination of third-party data sources, public information, and internal processing methods.

Because real estate data can be incomplete, delayed, corrected, or changed by the sources at any time, users should treat all information on this Platform as informational and verify details independently before making decisions. For additional information, please see our Disclaimer Notice located at: https://chimney.ai/disclaimer.

1. Data Sources

The information displayed or referenced on this Platform may come from one or more of the following categories:

Listing and property information

  • Active listings and related property details provided by third-party data providers, brokerages, or listing feeds
  • Listing metadata such as price, address, or approximate location, property type, size, room counts, features, listing history, and media (photos where available)

Historic and market context

  • Sold history and historic pricing information, where available, through third-party sources or public records
  • Aggregated market patterns such as price ranges, listing activity, and comparable property signals

Neighborhood and urban context

  • Publicly available or licensed datasets related to neighborhoods and communities, such as transit proximity, schools, amenities, and other location-based context
  • Urban and geo-economic indicators derived from public sources or reputable datasets

User inputs

  • Information a user provides during searches or through interactive features, including but not limited to conversational interfaces, preferences, feedback, and saved criteria

Important note

We do not control third-party data sources. A property’s details may be incomplete, inaccurate, duplicated, inconsistent across sources, or updated after it appears on this Platform. For additional information, please see our Disclaimer Notice located at: https://chimney.ai/disclaimer.

We are not affiliated with, endorsed by, or operated by any multiple listing service (MLS), real estate board, or brokerage, unless explicitly stated.

2. What We Do With the Data

We may process and organize information to make it easier to understand and compare, including but not limited to:

  • Standardizing formats (for example, normalizing addresses, property categories, or feature labels)
  • De-duplicating similar records and linking related listing events where possible
  • Aggregating statistics at different geographic levels (for example, neighborhood-level information)
  • Generating information to help users evaluate options more efficiently

These processes may involve automated methods and may not always reflect the full nuance of a specific property or situation.

3. Methodology and “Information”

Certain features may present “Information,” “scores,” “rankings,” “signals,” “comparisons,” or similar outputs intended to provide users with better information in order for the user to ascertain and explore tradeoffs on their own and/or ask better questions.

These outputs may be based on combinations of:

  • Available listing attributes and historic listing behavior
  • Geographic context and location-based indicators
  • Aggregated patterns and statistical comparisons
  • user-stated preferences and interactions (when applicable)

These outputs are not guarantees.

They are informational tools, not professional advice, and they may not capture factors that materially impact value or suitability, such as:

  • Interior condition, renovations, structural issues, noise, odors, pests, or building maintenance
  • Legal, title, zoning, permits, strata/condo rules, or special assessments
  • Financing conditions, appraisal outcomes, or lender-specific requirements
  • Micro-location factors (for example, a specific intersection, construction, traffic, or property-specific risks)

For additional information, please see our Disclaimer Notice located at: https://chimney.ai/disclaimer.

4. Accuracy, Timeliness, and Gaps

We make reasonable efforts to present helpful and relevant information, but we do not guarantee that:

  • Listings are complete or continuously available
  • A listing is still active, accurate, or unchanged at the time you view it
  • Sold history is complete or perfectly matched to the correct property
  • Neighborhood indicators fully reflect real-world conditions at a given moment

Real estate data can change quickly and may contain errors even in authoritative systems. If there is a discrepancy between this platform and the source, the source should be treated as the more authoritative source. For additional information, please see our Disclaimer Notice located at: https://chimney.ai/disclaimer.

5. User Verification and Professional Advice

Users should verify key details independently and consult qualified professionals before making decisions, including but not limited to:

  • Confirming listing details directly with the listing brokerage or licensed agent
  • Obtaining updated financing information from a financial institution or mortgage professional
  • Reviewing legal and contractual terms with qualified legal counsel
  • Completing appropriate inspections and due diligence

Nothing on this Platform should be interpreted as legal, financial, tax, investment, or professional real estate advice. For additional information, please see our Disclaimer Notice located at: https://chimney.ai/disclaimer.

6. Third-Party Links and Embedded Content

This Platform may include links to third-party websites, embedded tools, maps, or external content. We do not control third-party content and are not responsible for its accuracy, availability, or practices.

7. Changes to Data, Models, and Methods

We may update data sources, calculation methods, and internal processing over time to improve usefulness, accuracy, or performance. As a result:

  • Historical views may change
  • Previously displayed outputs may be updated
  • Information may differ as data improves and/or changes

8. Contact and Corrections

If you believe information on this platform is inaccurate or misleading, you can contact us through the website at https://chimney.ai/contact or emailing us at [email protected] to request a review. While we may investigate, we cannot guarantee that every issue can be corrected, especially when it originates from third-party sources.
