Markham Market Update for Sellers
This month's verdict: a holding pattern with more choice for buyers. TRREB's September 2026 Market Watch shows GTA sales down 9.0% year-over-year as economic uncertainty kept some buyers waiting. Markham recorded 245 sales at an average of $1,125,353 and a median of $1,051,000. Homes sold at 98% of list in 34 days, with 4.1 months of inventory: balanced, and tighter than York Region, Richmond Hill or Vaughan. New listings jumped as the fall market opened, and Markham's benchmark price is down 6.0% from a year ago. Sellers who price to today's comparables and launch complete are still selling.

The Bigger Picture
GTA and York Region, September 2026
| Metric (TRREB, September 2026) | Reading | Direction |
|---|---|---|
| GTA home sales | 5,040 (down 9.0% YoY) | Buyers in a holding pattern |
| GTA new listings | 16,500 (down 14.4% YoY) | Less supply than a year ago |
| GTA active listings | 26,131 (down 9.3% YoY) | Inventory still below last year |
| GTA average price | $1,006,409 (down 5.1% YoY) | Edged lower month-over-month |
| GTA HPI composite benchmark | Down 4.7% YoY | Edged lower month-over-month |
| GTA days on market | 34 listing / 51 property | Similar to a year ago |
| York Region | 893 sales, $1,136,650 average, 5.0 months of inventory | Markham was tighter at 4.1 months |
| Richmond Hill / Vaughan | $1,189,203 / $1,163,441 average; 5.6 / 4.9 months | Close to Markham on price, more supply |
What changed from August: TRREB described buyers as being in a holding pattern, with uncertainty about the economy, inflation and borrowing costs weighing on sales. On a seasonally adjusted basis, GTA sales, new listings and prices all edged lower from August. TRREB also pointed to substantial pent-up demand from households that intend to buy once they feel confident about jobs and rates.
What that means for a Markham seller: buyers have more homes to compare than they did in the summer, and they are taking their time. The homes that sell are priced to this month's comparables, fully prepared, and marketed to reach every serious buyer in the first two weeks. A home that launches high to "test the market" now competes with a larger fall inventory. See what a disciplined launch produced at 56 Ingleborough Court and 97 Mercer Crescent.
Markham's 2026 residential tax rate is 0.722889%, the lowest of Markham, Vaughan (0.749217%) and Richmond Hill (0.760104%). On every $1,000,000 of assessed value, that is about $7,229 a year in Markham.
TRREB's September report listed average posted mortgage rates of 6.09% for a five-year term and a prime rate of 4.5%. Buyers who are pre-approved and watching rates are the pent-up demand TRREB describes.

Selling Strategy
How to Sell Into the Fall Market
- 01
Price to the September comparables, not the spring ones
Markham's benchmark is down 6.0% from a year ago, so last spring's sales overstate today's value. The list price has to be defensible on day one. The method: data-driven pricing.
- 02
Launch complete
New listings rose to 729 in September, so buyers are comparing more homes. Staging, photography, video and full digital reach on day one turn that attention into offers. Standard: seller services.
- 03
Use the neighbourhood, not the city
Markham averaged $1,125,353 in September, but some communities sell above list in weeks while others negotiate for months. Your street's data decides your strategy.
- 04
Plan the timeline now
The fall window runs to late November before the seasonal slowdown. Sellers who prepare now can still launch before it closes, or prepare quietly for an early spring 2027 launch. If you have already bought, see buy before you sell.
“From the very first phone call, they showed true professionalism and confidence. They gave a clear analysis of my home, great advice on preparation, and marketed it to the right buyers. They didn't just focus on closing; they focused on the best result.”
Market Update Questions
For a well-prepared, accurately priced home, yes. Markham had 4.1 months of inventory in September 2026, which is balanced, and homes sold at 98% of list in 34 days on average. New listings rose as the fall market opened, so presentation and pricing matter more than they did in the summer. Homes priced above the comparables still sit. See is now a good time to sell?
TRREB's September 2026 Market Watch reported 245 Markham sales at an average of $1,125,353 and a median of $1,051,000, with 729 new listings, 1,122 active listings, 98% of list price and 34 days on market. Detached homes averaged $1,534,139 and condo apartments $574,612.
Year over year, yes. Markham's MLS® Home Price Index benchmark was $1,052,500 in September 2026, down 6.0% from a year earlier, slightly more than the GTA's 4.7% decline. Month to month, the average price fell from $1,208,692 in August to $1,125,353, partly because fewer detached homes sold. Prices vary widely by street and home type, so your own comparables matter most.
Mostly the mix. Detached homes made up 49% of Markham sales in August and 44% in September, and detached homes are the most expensive type. When fewer of them sell, the average falls even if values hold. The MLS® Home Price Index, which adjusts for mix, is the better guide to value, and it shows Markham down 6.0% year over year.
In September 2026, Markham averaged $1,125,353, Richmond Hill $1,189,203 and Vaughan $1,163,441. Markham had the lowest months of inventory of the three (4.1, against 5.6 and 4.9) and the highest sales-to-new-listings ratio, so it was the most balanced of the three markets. Markham also has the lowest 2026 property tax rate, at 0.722889%. See Markham vs Richmond Hill and Markham vs Vaughan.
