“MLS® home sales hovered at nearly the same level for the third straight month, delivering the strongest September performance since 2021. New listings surged from August and sat well above where we would expect for this time of year,” said Jeremy Guerette, President of the Sarnia-Lambton Association of REALTORS®. “The number of available homes at the end of September was virtually unchanged from a year ago and remained well above the historical norm for the month. The average price held steady, remaining above $500K for the sixth consecutive month. Newly listed homes continue to outpace sales by more than 2 to 1 and overall supply is hovering at elevated levels. As a result, market conditions look much the same as they have in recent months. If you are looking to buy or a sell a home in the near future, we recommend reaching out to a trusted local REALTOR® who can provide tailored insights and help devise a game plan that fits your goals.”
