What the twelve months say

• Days on market: the fastest of the twelve months was May 2026 (11 days), the slowest April 2026 (108 days); median of the twelve months, 68 days. September (68 days) is at the twelve-month median.

• New listings: 318 houses put up for sale from October 2025 to August 2026 (eleven full months), the busiest month being April 2026 (57) and the quietest December 2025 (5). August (27) is below June (34); September (24) covers only the first 16 days of the month.

• Across the 50 cities tracked, the September median is 16 days (June: 14 days; October 2025: 12 days); it lengthened since June in 30 cities and doubled in 7. September inventory is higher than June in 39 cities and higher than October 2025 in 44; it is at its twelve-month peak in 24 cities. 26 cities are in a seller's market, 20 in a balanced market, 4 in a buyer's market.

Months of inventory and verdict: a buyer's market

Rule: under 4 months of inventory = seller's market, 4 to 6 months = balanced market, over 6 months = buyer's market. Calculation in Westmount: 157 active houses in September ÷ (137 sales in 2026 ÷ 9 months = 15.2 sales a month) = 10.3 months. Verdict: a buyer's market. It is an approximation: 2026 sales stop on September 16 and are divided by nine full months, which nudges the result slightly upward; the actual pace of September may differ from the year's average. Westmount ranks 50th of 50, from the tightest market to the slowest (median of cities: 3.9 months).
