How Building Matching Works

How Building Matching Works

Building matching is the engine that connects pre-construction project data to MLS resale data for the same physical building.

Why matching matters

A project like "The Grand Toronto" in your pre-construction database and "80 Queen St W" in MLS data refer to the same building. The matching system links them so your site can show both datasets together.

How auto-matching works

The system uses an address-first matching strategy:

1. Address normalization — Both the pre-construction address and MLS addresses are cleaned and standardized (removing unit numbers, standardizing street suffixes)
2. Exact address match — If the normalized addresses match exactly, a high-confidence link is created
3. Fuzzy address match — If addresses are close but not identical (e.g., typos, different formats), a medium-confidence link is suggested
4. Reverse matching — MLS listings are also checked against pre-construction projects to catch matches in both directions

Confidence scoring

Each match receives a confidence score:

• High (0.9-1.0) — Exact address match, reliable
• Medium (0.7-0.89) — Fuzzy match, likely correct but worth verifying
• Low (below 0.7) — Possible match, manual review recommended

Manual matching

For buildings the system cannot match automatically, go to Admin > Building Links and:

1. Search for the pre-construction project
2. Search for the MLS building by address or name
3. Create the link manually

Matched data

Once a building is matched, the project page shows MLS resale listings, rental listings, building stats, and price comparisons automatically.
