Inventory and Buyer Trends
Inventory remains relatively tight, with 514 active listings on the market by the end of the month. While this reflects an increase in supply compared to earlier in the year, the demand continues to sustain price stability.

Homes priced between $400,000 and $599,999 dominated sales activity, accounting for nearly half of all transactions. This continues to reflect the affordability appeal of Sarnia compared to other Ontario markets.

What This Means for Buyers
Buyers should expect:

• Modest competition in popular price brackets
  
  
• Strong value in established family-friendly neighbourhoods
  
  
• More options coming onto the market, but acting fast remains crucial
  
  

Tip: Get pre-approved and work with a local agent to jump on opportunities.

What This Means for Sellers
Sellers should take note:

• Homes in good condition and priced competitively are moving quickly
  
  
• The fall market remains active, especially in Sarnia proper and Lambton Shores
  
  
• Staging and professional photography can give you the edge in today’s visual-first market
  
  

Market Outlook: Fall 2025
Looking ahead, we expect continued balanced conditions with minor fluctuations in pricing. Economic stability and interest rates will play a key role in shaping demand. If rates remain steady or ease slightly, buyer activity could increase further.
