Dundas entered the fall real estate market with more homes available, longer selling times and a wider gap between original asking prices and final sale prices.

According to residential MLS® statistics from Cornerstone’s Matrix system, Dundas recorded 5.4 months of inventory in September 2026, compared with 4.2 months in September 2025. The median time required to sell a home increased from 19 to 35 days, while the average sale price relative to the original asking price declined from 95.6% to 94.4%.

These figures suggest a market in which buyers have more time to evaluate their options and sellers face greater pressure to establish a competitive asking price from the outset.

However, the market is not moving uniformly. Pricing, property condition, location and the competition within individual price ranges remain important considerations.

1. Dundas Buyers Have More Choice Than a Year Ago

One of the clearest changes in the Dundas market is the relationship between available inventory and the pace of sales.

In September 2026, there were 81 active residential listings, compared with 92 in September 2025. That represents approximately a 12% reduction in the number of properties available.

At first glance, fewer active listings might suggest tighter market conditions.

Yet months of inventory tells a different story.

Dundas recorded 5.4 months of inventory in September 2026, up from 4.2 months one year earlier – an increase of approximately 29%.

Months of inventory measures the number of months it would take to sell the available supply of homes at the current sales pace, assuming no additional properties entered the market.

This distinction matters because inventory levels alone do not tell us how effectively the market is absorbing available homes.

The combination of fewer active listings and more months of inventory is consistent with a slower rate of sales relative to available supply.

For buyers, this can mean more opportunity to compare properties and consider their decisions carefully. For sellers, it reinforces the importance of understanding the homes they are competing against, rather than relying exclusively on broader market averages.

2. Homes Are Taking Longer to Sell

Marketing time provides another useful indication of changing market conditions.

In September 2025, the median time required to sell a residential property in Dundas was 19 days. By September 2026, that figure had increased to 35 days.

That’s an increase of 16 days, or approximately 84%.

The average time to sell also increased, from 31 days to 47 days over the same period.

These changes are meaningful because the longer a property remains on the market, the more important it becomes for sellers to reassess how their home is positioned relative to competing listings.

Longer selling times do not necessarily mean a property is undesirable or that a seller must reduce their price. A home may require more time because of its price range, distinctive characteristics or the size of its potential buyer pool.

However, sellers should establish a clear strategy before listing, including how they will evaluate showing activity, buyer feedback and changes in competing inventory.

3. Sellers Are Receiving Less Relative to Their Original Asking Prices

Another important development is the relationship between what sellers initially ask for their homes and what buyers ultimately pay.

In September 2026, Dundas residential properties sold for an average of 94.4% of their original asking prices, compared with 95.6% in September 2025.

That represents a decline of 1.2 percentage points.

For perspective, consider a home originally listed for $1 million. A sale at 94.4% would represent $944,000, compared with $956,000 at 95.6% – a difference of $12,000.

This is an illustration of the ratios, not a prediction of what any particular property would sell for.

There is also an important distinction between the original asking price and the final asking price.

The original-price ratio captures the relationship between the property’s initial asking price and its eventual sale price. The final-list-price ratio compares the sale price with the asking price in effect when the property sold.

In September 2026, Dundas homes sold for an average of 95.9% of their final asking prices, compared with 94.4% of their original asking prices.

The difference reinforces why sellers should pay attention to both measures. A property may undergo price adjustments during its marketing period, and the final asking price does not necessarily reflect where the seller began.

It would be misleading to interpret these ratios as proof that every buyer negotiated a particular discount. The statistics describe aggregate relationships between asking and selling prices, not the circumstances of individual transactions.

What does this mean for someone preparing to sell?

The O’Reilly Group‘s interpretation is that the initial pricing decision deserves particular attention in the current market.

An ambitious asking price may be appropriate in certain circumstances, but it should be supported by relevant comparable sales, competing inventory and the property’s individual characteristics.

Sellers should also understand the difference between testing an asking price and establishing a price that is likely to attract serious consideration from qualified buyers.

A pricing strategy should account for what happens if the market response is weaker than anticipated.

4. Asking Prices Have Changed, but That Does Not Mean Every Home Has Lost the Same Value

The average asking price of Dundas residential listings in September 2026 was $1,036,645, compared with $1,324,266 in September 2025.

That’s a decrease of approximately 21.7%.

The median asking price declined from $1,049,950 to $849,900, a reduction of approximately 19.1%.

These are substantial changes in the composition and pricing of homes being offered for sale.

However, they require careful interpretation.

Average and median asking prices are not measures of how much an individual property’s market value has changed.

The types of properties entering the market can vary significantly from one month to another. A month containing a larger share of high-end detached homes may produce a much higher average asking price than a month dominated by more modestly priced properties.

Dundas has a diverse housing stock, ranging from smaller historic residences and townhomes to larger detached homes and rural properties. Comparing these properties without accounting for their differences can produce misleading conclusions.

The original asking-price statistics also offer useful context. The average original asking price was $1,039,866 in September 2026, compared with $1,346,217 one year earlier.

The median original asking price declined from $1,112,450 to $849,900.

These figures support the conclusion that the asking-price mix was lower in September 2026. They do not establish an equivalent decline in the market value of comparable Dundas homes.

For homeowners trying to understand what their property may be worth, recent comparable sales involving similar homes remain more informative than a single municipality-wide average.

5. The Fall Market Is Showing More Signs of Slower Absorption

The September figures become more revealing when examined alongside the preceding months.

In July 2026, Dundas had 2.6 months of inventory. That increased to 5.2 months in August and 5.4 months in September.

Over the same period, the median time to sell increased from 23 days in July to 28 days in August and 35 days in September.

New listings were also lower than a year earlier.

September 2026 recorded 37 new residential listings, compared with 50 in September 2025 – a decline of 26%.

Meanwhile, the number of expired listings reached 47 in September 2026, compared with 55 in September 2025.

The expired-listing count was lower year over year, but remained elevated relative to several months earlier in 2026, including May, when 15 listings expired.

An expired listing does not necessarily mean the homeowner abandoned plans to sell. Properties may be relisted, marketed differently or withdrawn from the market for reasons not captured by the statistics.

Taken together, these indicators suggest that the Dundas market experienced a more challenging late-summer and early-fall selling environment than the spring months.

Seasonality may contribute to some of these changes, but the available figures do not establish how much of the slowdown is seasonal rather than a broader change in demand.

What Does the September Market Mean for Dundas Homebuyers?

For buyers considering a home in Dundas, the current figures provide several reasons to approach the process with preparation rather than urgency.

A market with 5.4 months of inventory and longer median selling times may offer more opportunities to evaluate properties, arrange appropriate due diligence and negotiate terms.

That does not mean every home will be available for an extended period or that every seller will accept an offer below asking.

Well-positioned properties can still attract strong interest, particularly when their location, condition and asking price compare favourably with competing options.

Buyers should focus on three questions:

How does the asking price compare with recent sales of similar properties?

How long has the home been available, and has its asking price changed?

What conditions, closing arrangements and due diligence are appropriate for the property?

The amount of inventory across Dundas is useful background information, but the number of comparable properties available within a buyer‘s specific budget is often more relevant to an actual purchasing decision.

What Does the September Market Mean for Dundas Home Sellers?

For homeowners preparing to sell, September’s statistics reinforce the importance of a deliberate, evidence-based strategy.

The average time required to sell has increased, the median marketing period has lengthened and sale prices are averaging a lower percentage of original asking prices than one year earlier.

In this environment, sellers should give particular attention to the preparation, presentation and pricing of their property before it reaches the market.

That means evaluating competing listings, identifying the features that distinguish the home and understanding how buyers may compare it with other available options.

It also means establishing a plan for reviewing market response.

A successful selling strategy is not simply about choosing an asking price. It involves understanding the competitive environment, presenting the property effectively and making informed adjustments when new information becomes available.

What Should Existing Dundas Homeowners Take Away?

Homeowners who are not actively buying or selling may be concerned when they see headlines about declining prices or slower market conditions.

The distinction between asking-price statistics and actual property values is especially important.

The decline in Dundas‘ average asking price does not mean that every homeowner has experienced an equivalent reduction in equity.

Market value depends on the characteristics of the individual property and the prices buyers are willing to pay for comparable homes.

For homeowners considering renovations, refinancing, downsizing or a future move, a property-specific valuation supported by recent sales is a more appropriate starting point than broad averages.

Those planning to sell one home and purchase another should also consider both sides of the transaction together. Changes in the value of the property being sold may be accompanied by changes in the cost of the property being purchased.

What We Will Be Watching in October 2026

The next monthly report should help clarify whether the slower conditions observed in August and September are continuing.

Several indicators deserve attention.

First, months of inventory will help establish whether available supply is being absorbed more quickly or slowly.

Second, median and cumulative days on market will help show whether longer marketing periods are becoming more common.

Third, the relationship between original asking prices, final asking prices and selling prices will provide further insight into pricing conditions.

Finally, new listings, active inventory and expired listings will help explain how the supply of homes is changing.

These indicators should be evaluated together rather than interpreted individually. One month of data can be influenced by the timing and mix of transactions, particularly in a relatively small market.

A Market That Rewards Preparation

September’s Dundas statistics point to a market where buyers have more time and sellers face a greater need to establish a thoughtful strategy.

The most meaningful changes are not simply the asking-price averages. They are the increase in months of inventory, longer selling periods and lower sale-to-original-price ratios.

For buyers, these conditions may create opportunities to make more deliberate decisions.

For sellers, they emphasize the value of understanding the competition before establishing a price and bringing a home to market.

And for existing homeowners, they provide a reminder that broad market statistics are a starting point, not a substitute for evaluating an individual property.

Frequently Asked Questions About the Dundas Real Estate Market

1. Is Dundas a buyer’s market in September 2026?

Dundas recorded 5.4 months of residential inventory in September 2026, compared with 4.2 months one year earlier. This indicates more supply relative to the current sales pace. The market is showing conditions more favourable to buyers than a year earlier, although months of inventory alone does not establish a universal buyer‘s-market classification. Conditions may differ considerably by property type, location and price range.

2. How long does it take to sell a home in Dundas?

The median time required to sell a residential property in Dundas was 35 days in September 2026, compared with 19 days in September 2025. The average was 47 days. These are historical figures for properties that sold during the reporting period, not guarantees for current listings. Actual selling time depends on pricing, property condition, location and competition.

3. Are Dundas house prices falling in 2026?

The average asking price of Dundas residential listings declined by approximately 21.7% between September 2025 and September 2026. However, asking-price averages are not the same as sold prices or quality-adjusted home values. Changes in the types of homes listed can substantially affect the average. The supplied statistics do not establish how much comparable Dundas homes have appreciated or depreciated.

4. How much below asking price are Dundas homes selling for?

In September 2026, Dundas residential properties sold for an average of 94.4% of their original asking prices and 95.9% of their final asking prices. These ratios describe aggregate selling outcomes. They do not mean every property sold below asking or that buyers should expect the same discount on a particular home. Comparable sales and the property’s pricing history provide more useful guidance.

5. How many homes were available for sale in Dundas in September 2026?

Dundas recorded 81 active residential listings in September 2026, compared with 92 in September 2025. Although the number of active listings declined, months of inventory increased from 4.2 to 5.4. This illustrates why the number of available properties should be considered alongside the pace of sales when evaluating supply and demand.

6. Is fall 2026 a good time to buy a home in Dundas?

The September statistics suggest that buyers may have more time to compare properties and evaluate their options than they did one year earlier. However, whether it is a good time to buy depends on personal finances, housing needs, expected ownership period and the specific property. Market conditions should inform a purchase decision, rather than determine it independently.

7. Should I reduce my asking price if my Dundas home is not selling?

A price reduction may be appropriate when a home’s asking price is not supported by comparable sales or competing inventory, but it should not be automatic. Sellers should review the property’s marketing exposure, showing activity, feedback, presentation and current competition. September’s longer selling times make it especially important to distinguish between a home that requires patience and one that may need repositioning.

8. What is the difference between days on market and cumulative days on market?

Days on market generally measures the marketing period associated with a listing, while cumulative days on market (CDOM) accounts for additional listing history under the MLS® system’s applicable rules. In September 2026, Dundas recorded a median cumulative days on market of 77, compared with a median days to sell of 35. These measures should not be treated as interchangeable because their counting methods and underlying listing histories differ.

Data Sources and Methodology

This report was prepared using residential MLS® statistical exports from the Cornerstone Matrix system, extracted October 8, 2026, covering January 2025 through September 2026.

The geographic scope is Dundas, identified in Matrix as Hamilton Municipality/Area 41 – Dundas. The property classification is Residential.

The analysis includes supplied statistics for active listings, new listings, months of inventory, asking prices, days to sell, cumulative days on market, expired listings, price-per-square-foot measures and sale-to-asking-price ratios.

All year-over-year comparisons use September 2025 and September 2026 unless otherwise indicated. Percentage changes were calculated from the reported values, with percentage-point differences used for ratios.

The report does not present a verified September sold-unit count, average or median sold price, or MLS® Home Price Index benchmark because those measures were not established from the available evidence used in this article. Asking-price changes should not be interpreted as equivalent changes in property values.

Statistics reflect the underlying MLS® search criteria and may be subject to revisions, differing metric populations and listing-status conventions. The analysis and consumer interpretation are those of The O’Reilly Group, not an official market report or forecast issued by Cornerstone.
