September’s real estate numbers are in, but rather than looking at just one month, I think the year-to-date numbers tell us a much better story about what is happening in the Sarnia-Lambton real estate market in 2026.
And the biggest takeaway?
More homes are being listed. Fewer homes are selling. Buyers have choices.
That doesn’t mean homes aren’t selling. They absolutely are. But this is a market where pricing, presentation, marketing, strategy and experience matter.
The Year-to-Date Numbers Tell the Bigger Story
From January through September 2026, there have been 2,547 residential listings in Sarnia-Lambton, up 4.73% compared with the same period in 2025.
During that same time, 1,067 residential properties sold, down 7.38%.
The year-to-date average residential sale price is $526,059, down 2.49% from $539,486 last year.
The year-to-date median residential sale price is $460,000, compared with $485,000 in 2025, a decrease of 5.15%.
Put all of that together and we have more homes coming to market and fewer homes selling.
What does that mean?
Buyers have choices.
And when buyers have choices, they can afford to be more selective.
What Does This Mean if You’re Selling?
This is not the market where I would recommend throwing a price on your home and “seeing what happens.”
Buyers are comparing your home with everything else available to them.
Price matters. Presentation matters. Marketing matters.
If another home offers better value, better presentation or simply feels like the better choice, buyers can move on.
That doesn’t mean homes aren’t selling. There were still 120 residential sales in September alone.
It means sellers need a strategy.
The first few weeks your home is on the market are important because buyers who have already been waiting for a property like yours are often among the first people to see it.
You want to give those buyers a reason to book a showing, not a reason to wait for a price reduction.
Experience Matters in This Market
I’ve been selling real estate in Sarnia-Lambton since 2013 and have helped sell hundreds and hundreds of homes. In that time, I’ve worked through some very different real estate markets.
I’ve seen markets where homes sold almost as quickly as we could list them, markets where multiple offers were the norm, and markets like this one, where buyers have more choices and sellers need to be much more strategic.
Experience matters differently in a changing market.
It’s not just about knowing how to sell a house when everything is selling. It’s knowing what to do when a home isn’t selling.
Is the price the problem? Is it presentation? Are buyers choosing competing homes instead? Has the market shifted since the home was originally priced? Do we need to change the marketing, reposition the property or adjust our strategy?
Those are conversations I’ve had hundreds of times over the years.
Today’s market requires more than putting a sign on the lawn and uploading a listing to MLS®. It requires understanding the numbers, watching what buyers are actually doing and being willing to adjust when the market gives us feedback.
The goal isn’t simply to list your home. The goal is to get it sold.
What About Buyers?
For buyers, having more inventory can create opportunity.
You may have more time to compare homes, do your due diligence and negotiate than you did in some of the much faster markets we experienced a few years ago.
But more inventory does not mean every seller is desperate or every house will sell below asking.
A great home in a desirable location that is priced appropriately can still attract attention quickly.
For buyers, experience matters too. Understanding recent comparable sales, how long a property has been on the market and where there may be room to negotiate can make a big difference.
What Happened in September?
September continued many of the trends we’ve been seeing throughout 2026.
There were 300 new residential listings, compared with 329 in September 2025, a decrease of 8.81%.
There were 120 residential sales, compared with 131 last September, a decrease of 8.40%.
The average residential sale price was $496,123, down 3.49% from $514,058 in September 2025.
Interestingly, the median residential sale price increased 1.15% to $450,000, compared with $444,900 last September.
The average price went down while the median went up.
That’s a great reminder of why I don’t believe one monthly statistic should ever be used to tell you what is happening to the value of your home.
There Isn’t Just One Sarnia-Lambton Real Estate Market
Real estate is incredibly local.
What’s happening with a bungalow in Sarnia’s North End can be very different from a country property, a home in Petrolia, a waterfront property in Bright’s Grove or a first-time-buyer home under $400,000.
Even two homes in the same neighbourhood can perform differently depending on condition, updates, square footage, lot, garage, layout, location and price.
That’s why an online estimate or a headline saying “prices are down” doesn’t tell you what your house is actually worth.
If you’re considering selling, buying or simply wondering where you stand in the 2026 Sarnia-Lambton real estate market, I’m always happy to look at the numbers that actually apply to you.
I’ll look at your home, recent comparable sales and the properties currently competing for the same buyers.
There’s no pressure and no obligation. It’s simply helpful local information so you can understand your options and make a plan that feels right for you.
Experience matters, but so does having a plan that fits today’s market, not yesterday’s.
