What it changes when selling or buying a condo in Westmount
At 9.3 months of inventory, the condo in Westmount is a buyer's market in 2026: there are more condominiums for sale than ready buyers, and a unit listed at its 2022 price stays listed. For a condo seller, the entry price is everything: buyers compare 166 units, look at the condo fees and the contingency fund, and move on to the next one. For a buyer, this is the time to visit more than once, to negotiate, and to include an inspection condition without losing the unit. Houses are at 9.0 months: condos and houses sell at roughly the same pace in Westmount, which makes life easier for whoever sells one to buy the other.
How to read these figures
"Active listings" counts the condominiums for sale on Centris at the end of each month; we publish the average of the year's twelve month-ends (nine in 2026) and the last month's value. "New listings" adds up the year's listings, including relistings after a withdrawal. Condo 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 condos for sale by monthly sales. The "houses" column repeats the same calculation for single-family homes in Westmount.
