What the twelve months say

• Days on market: the fastest of the twelve months was July 2026 (7 days), the slowest January 2026 (90 days); median of the twelve months, 34 days. September (48 days) is above the twelve-month median.
• Inventory: 14 active houses at the low (December 2025), 40 at the peak (September 2026). September is the peak of the twelve months: there have never been as many houses for sale in the window.
• New listings: 131 houses put up for sale from October 2025 to August 2026 (eleven full months), the busiest month being May 2026 (23) and the quietest October 2025 (5). August (12) is level with June (12); September (11) covers only the first 16 days of the month.
• Price: houses sold at 99% of asking in September, +2 points from June; over the twelve months, 2 of 11 months closed above asking (ratio of 100% or more), the highest in May 2026 (100%). The median price of a house in L'Île-Perrot is $561,500 in 2026 to date (51 sales from January to September) against $545,000 in 2025 (101 sales), +3.0%.
• 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 L'Île-Perrot: 40 active houses in September ÷ (51 sales in 2026 ÷ 9 months = 5.7 sales a month) = 7.0 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. L'Île-Perrot ranks 48th of 50, from the tightest market to the slowest (median of cities: 3.9 months).
