Duplicate Properties: Keeping the Data Clean

In a collaborative network, data quality is paramount. When listing a property, each entry includes vital details such as the property’s price, features, and photos. PropertyList enforces protocols to manage overlapping inventory and maintain an accurate database.

1. Identifying Duplicates

To protect the integrity of the MLS, PropertyList utilises advanced algorithms alongside human oversight to identify potential duplicate listings. The infrastructure actively compares visual media, property details, and other relevant geographical information to determine if multiple entries represent the exact same property.

2. Selecting the Main Listing

When duplicates are confirmed within the ecosystem, the system designates a "Main Listing." This primary mandate is chosen based on a dynamic quality point system.

The algorithm rewards the version of the listing with points:
  • The highest-quality professional photos
  • The most detailed information
  • Overall data completeness
  • Chronological priority (the first listing uploaded)
  • Whether it was deployed by a Verified Agency
This selection ensures the most informative version is displayed as the primary result.

3. Reporting Duplicates

Agents act as quality controllers within the ecosystem. If you spot a duplicate or unavailable property on the MLS, you can formally report the listing. These reports are swiftly reviewed by the PropertyList team to verify the overlap and merge any duplicate entries or remove any inactive or fraudulent listings, protecting your exclusive mandates.

4. The MLS Duplicate Section

Transparency is crucial for professional co-broking. Agents within the MLS can see all duplicate listings housed in a dedicated section attached to the Main Listing. This section clearly displays the holding agency name, the asking price, the commission offered, and provides a direct link to view the alternate property version.

5. Maintaining Database Accuracy

PropertyList continuously monitors the shared network to ensure ongoing accuracy and prevent future duplicates from cluttering the search results. You should regularly update your listings to keep the information current and protect your listing's quality score.
By following these automated and community-driven steps, PropertyList maintains an accurate digital real estate database to help agents and buyers find the property they need.
