It has been brought to our attention that some listings in the system may not be showing complete property history. Property history relies on unique property identifiers to link to historical listing data. The unique identifiers used in this process are made up of a combination of key listing fields including Region, Municipality, Neighbourhood, Street Address, City and Postal Code. Recently, PIN and Roll number (if available) have been added to the logic to provide improved accuracy.
In many instances where a problem with property history has been reported, inconsistencies in the property address across the historical listings are the cause (usually a City or Street name). In these cases, staff have been able to make adjustments to the field(s) causing the inconsistency, allowing the unique identifiers to match and history to properly link.
The below example illustrates how Property History may become broken because of an inconsistent address across two listings:
Listing #1
1234 #65 Regional Road
West Lincoln, Ontario
L0R 1Y0
Unique Identifier: L0R1Y01234#65REGIONALROADWESTLINCOLNONTARIO
Listing #2
1234 #65 Regional Road
Smithville, Ontario
L0R 1Y0
Unique Identifier: L0R1Y01234#65REGIONALROADBEAMSVILLEONTARIO
In effort to avoid inconsistent entry of listing addresses we recommend using the Fill from Geowarehouse function in Matrix Input.
If you encounter a listing which is missing property history, please use the Report Data Error link in Matrix to notify RAHB MLS® Helpdesk Staff of the issue so it can be investigated and corrected.
