| September 2026 Market Update
722 Homes for Sale in Sarnia-Lambton. So Why Aren't Prices Falling? Inventory hit a 10-year September high, sales slipped, and the benchmark pr bed to 5.6, the top edge of a balanced market. You might expect prices to be sliding fast. They aren't. The MLS® Home Price Index benchmark moved just 0.2% from August. The market isn't crashing. Leverage is slowly shifting from sellers to buyers, and which side of that you're on matters. |

Why I lead with the HPI, not the average
The MLS® Home Price Index tracks the value of a typical home, priced the same way every month. The average price only reflects whatever happened to sell, so a handful of luxury sales (or a lack of them) can swing it several percent. This month shows why. The average fell 5.1% while the median rose 3.1%. The HPI tells you values are essentially flat: -0.2% month over month and +0.2% over six months. |
What's Actually Happening
Start with supply. New listings were actually down 4.5% from last September, so sellers aren't flooding the market. The issue is absorption. Buyers aren't taking homes off the market as fast as they come on, so inventory keeps stacking up: 692 active listings in August, 722 in September. Year-to-date new listings of 2,775 are the highest January–September total in the 2016–2026 data.
Demand has been soft all year, not just this month. The 128 September sales compare with 158 in September 2019 and 168 in both 2016 and 2021. Year-to-date sales of 1,134 are the lowest in that same 10-year window. This isn't a slow-winter hangover dragging down the YTD numbers. Monthly and year-to-date figures tell the same story.
Prices tell a more nuanced one. The benchmark is down 3.4% from a year ago and 7.3% from three years ago, but it has been essentially flat since spring. The split between average (-5.1%) and median (+3.1%) is a mix shift. Fewer high-end homes sold this September, pulling the average down, while the middle of the market held firm. Dollar volume fell 16.2% against an 11.7% drop in units, which fits that picture.
The style breakdown matters too. One-storey homes have a benchmark of $532,400 and are down only 1.9% year over year. Two-storey homes, at $434,500, are down 5.6%. Bungalows are holding. Two-storeys are where the softness is.

The months-of-inventory rule
Under 4 months = seller's market | 4–6 months = balanced | Over 6 months = buyer's market.At 5.6 months, Sarnia-Lambton is still technically balanced, but the trend is clear: 4.5 a year ago, 5.1 in August, 5.6 now. For context, September 2021 sat at 0.9 and September 2019 at 2.0. |
What Buyers Need to Know
- You have negotiating room. Homes are selling at about 96% of asking, roughly $18,000 under list on a typical home. Listings sitting 30+ days are where you push on price, conditions and closing dates.
- Get a rate hold now. Markets are now pricing in a possible rate hike. A hold locks today's rate while you shop.
- Know where the deals are. Two-storey values are down 5.6% year over year. Bungalows are down only 1.9% and remain the most competitive segment.
- Fall is a smart window. Choice is high and competition is lighter before the winter slowdown.
- Don't wait for a crash. Prices have been flat for six months, not falling. Waiting for a big drop is a bet the data doesn't support.

Variable vs. Fixed: Where Rates Sit (as of October 7, 2026)
Best 5-year fixed: ~4.34% | Best 5-year variable: ~3.40% | Prime: 4.45%Variable is almost a full point cheaper today. But with inflation risks rising and markets pricing in possible hikes for 2027, only choose variable if your budget can handle a payment increase. Fixed rates follow bond yields, which remain elevated, so they could move before the Bank of Canada does. |
What Sellers Need to Know
- You're competing with 722 other listings. Price off today's comparables, not 2022, and not last spring.
- The first two to three weeks decide it. Median days on market is 28. Listings that miss that window go stale and end up chasing the market down.
- Price to your style. Bungalow owners are in the strongest position. Two-storey sellers need sharper pricing to stand out.
- Presentation matters more when buyers have choice. Staging, photos and pre-listing repairs pay off in a balanced market.
- Waiting for spring isn't automatically safer. If rates rise in 2027, buyer budgets shrink, not grow.

The National Picture
| Indicator | Latest | What it means |
|---|---|---|
| Bank of Canada policy rate | 2.25% (held Sept 2) | No change since October 2025. Next decision is October 28. |
| Prime rate | 4.45% | Unchanged. Variable-rate payments are stable for now. |
| National sales (August) | ▼ 6.9% YoY | Flat for the fourth straight month (-0.7% m/m). |
| National MLS® HPI | ▼ 3.0% YoY | Sarnia-Lambton (-3.4%) is tracking right in line with Canada. |
| National months of inventory | 4.8 | Balanced nationally. Sarnia-Lambton is looser at 5.6. |
| CREA 2026 forecast (July) | Sales -1.4%, price +1.1% | 2027 called for +3.7% sales, but that assumed stable rates. |
The biggest change from last month is the tone on interest rates. At its September 2 decision, the Bank of Canada held at 2.25% but flagged that upside risks to inflation have increased and the U.S. trade war is re-escalating. CREA's senior economist noted that a rate hike is "back on the table" and already priced in by markets. A few months ago, everyone was asking when the next cut would come. Now the question is whether rates go up. Markets currently put roughly an 80% chance on another hold on October 28.
Policy Watch: First-Time Buyer GST Rebate
The federal First-Time Home Buyers' GST/HST Rebate is now open for applications through CRA. It applies to newly built or substantially renovated homes where the purchase agreement was signed on or after March 20, 2025. Builders can credit the rebate at closing. It doesn't apply to resale homes, but if you're a first-time buyer considering new construction in Sarnia-Lambton, it can make a significant difference.

Local Insights: Most Popular Home Styles
| Rank | Style | Homes Sold | Average Price |
|---|---|---|---|
| 1 | Bungalow | 58 | $490,017 |
| 2 | 2 Storey | 16 | $553,369 |
| 3 | Raised Ranch | 13 | $569,946 |
| 4 | 1½ Storey | 9 | $414,583 |
| 5 | Side Split 4 Level | 6 | $475,817 |
Bungalows made up nearly half of all residential sales, almost four times the next most popular style. That demand is also why one-storey values are holding up best in the HPI.
Where buyers are actually shopping
The busiest price range was $400,000–$499,999 (32 sales), followed by $300,000–$399,999 (25) and $500,000–$599,999 (22). About 60% of all sales landed between $300K and $600K, and roughly a third sold under $400K. The upper end is still active, with 21 sales above $700K, including 7 over $1 million.
Neighbourhood Breakdown
| Area | Sept Sales | Sept Avg Price | YTD Sales (vs. 2025) | 12-Month Avg Price |
|---|---|---|---|---|
| Sarnia North (DISTSN) | 72 | $477,653 | 606 (▼ from 708) | $484,469 |
| Point Edward / Lakeshore (DISTPL) | 7 | $772,614 | 97 (vs. 100) | $726,281 |
| DISTSL | 18 | $460,456 | 143 (▲ from 137) | $538,176 |
| DISTEN | 9 | $428,300 | 90 (▲ from 72) | $484,812 |
| DISTLA | 3 | $537,000 | 51 (▼ from 54) | $565,018 |
| DISTBR | 2 | $435,000 | 13 (vs. 13) | $447,282 |
Sarnia North is still the volume leader by a wide margin, but year-to-date sales there are down about 14%, which accounts for most of the region's slowdown. Point Edward / Lakeshore remains the top-priced area, and its 12-month average has risen to $726,281 from $708,731 a year ago. DISTEN is a quiet growth story, with year-to-date sales up 25%.
What's Coming Next
- October 28: Bank of Canada decision. A hold is expected. Watch the tone for any signal of a hike.
- Mid-October: CREA's September national data. It will show whether the national stall continues.
- Bond yields. They drive fixed mortgage rates and could move before the Bank of Canada does.
- U.S. tariffs. Escalation is a real risk for Sarnia's industrial base and local employment.
- Inventory vs. the 6-month line. The seasonal slowdown in October–December typically pushes months of inventory higher. If we cross 6.0, Sarnia-Lambton officially tips into buyer's-market territory.
Final Thoughts
September confirmed the trend that's been building all year. There's plenty of supply, demand is muted, and prices are flat rather than falling. For buyers, that means real choice and real negotiating power, especially with two-storey homes and listings that have sat. For sellers, it means pricing and presentation decide the outcome more than timing does. The wild card is interest rates. If the conversation keeps shifting toward hikes, today's balanced market could look very different by spring.
Whether you're buying, selling or just want to know where your home stands, the right strategy starts with the right numbers. I'm happy to walk you through them.
