Homes for sale · Westmount · Centris 2016-2026
The number of houses for sale in Westmount at each month-end, and the number of new listings, year by year since 2016: the peak, the frenzy trough, the absorption rate, months of inventory, and why prices doubled without sales growing. Centris figures, not estimates.
In Westmount, an average of 145 houses were for sale on Centris at each month-end in 2026 (January to August), against 137 in 2016: inventory is 106% of what it was ten years ago, a milder decline than in most of the 50 cities tracked (median 46%).

What ten years of inventory say in Westmount
- Four markets in ten years in Westmount: 109 homes for sale on average in 2016-2019, 96 during the 2020-2022 frenzy, 122 when high rates returned, 138 in 2025 and 145 in 2026.
- Inventory peak: 2025 (138); trough: 2021 (75). Between the two, the choice offered to a buyer was divided by 1.8.
- New listings: 351 in 2025 at the high, 260 in 2021 at the low. New listings increased (+17% since 2016) and inventory still melted: everything that gets listed sells.
- Absorption rate (year's sales ÷ new listings): 76% in 2016, 72% in 2021, 57% in 2025. Nearly one home in two listed does not sell within the year: the asking price does the sorting.
- Months of inventory (homes for sale ÷ monthly sales): 7.3 in 2016, 4.8 at the 2021 trough, 8.3 in 2025, 9.0 in 2026. Under 4 months, the seller leads; above 6, the buyer.
- 2026 (Jan. to Aug.) versus 2025: average inventory is up 5% (138 to 145), and new listings are running at 416 at an annual pace (+19%, a simple twelve-month projection). Choice is coming back a little, without returning to 2016. End of August 2026: 147 active houses.
- Across the 50 cities tracked, 2026 inventory is a median 46% of 2016, it is at half or less in 32 cities, and it is climbing versus 2025 in 43 cities.
What it changes when selling or buying in Westmount
At 9.0 months of inventory, Westmount leaves more room to the buyer than most of the cities tracked: they can visit several houses, compare, and sometimes negotiate. For a seller, the listing price matters more than elsewhere, because the buyer has alternatives. It is not a buyer's market in the 2016 sense (7.3 months), but an overpriced house stays listed. The rest of the table explains prices: with 6% fewer homes for sale than in 2016, the median price doubled without the number of sales growing, and it will not come down until inventory does come back.
How to read these figures
"Active listings" counts the single-family houses for sale on Centris at the end of each month; we publish the average of the year's twelve month-ends (eight in 2026) and the last month's value. "New listings" adds up the year's listings, including relistings after a withdrawal. Sales come from the same database (number of sales in Westmount). Absorption divides sales by the same year's new listings; months of inventory divide homes for sale by monthly sales, as in the buyer's or seller's market in Westmount, computed there over the past twelve months.
