Cornerstone Association of REALTORS Narrative

The statistics provided in this report are based on information from the ITSO MLS® System. Multiple MLS® Systems operate within Ontario, and while none can be guaranteed to include every property listed or sold within a given area, they effectively illustrate market trends.

“Home sales in the Hamilton-Burlington area recorded another low for September, with six fewer sales than in September 2023. The number of new listings picked up from August, but they were still down 22.0% per cent from the same period last year,” said Bill Duce, CEO of Cornerstone. “Buyers and sellers are continuing to take a measured approach; however, the MLS® Home Price Index is only down modestly from last month and last year, which suggests the market is finding a degree of stability rather than experiencing sharp corrections. If you’re considering making a move, connect with a local REALTOR® who knows your community and can help you make an informed, confident decision.”
