What it changes when selling or buying in Westmount
In Westmount, the market weighs more in dollars with fewer transactions: each sale counts for more, and there are fewer houses to compare when setting a price. For a seller, this is a market where low inventory sets the price, not the number of buyers; for a buyer, comparables are scarce and recent, so the asking price weighs more than the statistic. A record volume does not mean that "everything sells": it means that what sells, sells dear. The number of sales by property type, house, condo and plex, is in home sales in Westmount.
How to read these figures
Sales volume adds up the sale prices of every single-family house sold in the year on Centris for the whole municipality of Westmount. The number of sales in this table comes from the same query (volume divided by average price); it may differ by a few units from our home sales page, harvested on September 16. The price obtained relative to the asking price, transaction by transaction, is in sold over asking. 2026 (Jan. to Sep.) is a partial year: the yearly pace multiplies nine months by twelve over nine, which ignores seasonality.

Does a record volume mean it is time to sell?
No, not on its own. Volume says how many dollars circulate, not how fast nor at what price relative to asking. To decide, cross it with days on market and inventory: days on market in Westmount and homes for sale and inventory in Westmount.
