What it changes when selling or buying a condo in Sainte-Thérèse
At 4.0 months of inventory, the condo in Sainte-Thérèse is a balanced market in 2026: enough units for a buyer to compare, few enough for a well-priced seller to find a buyer within weeks. Pricing makes the difference: a condo priced at the building's latest sales sells, a condo at its 2022 price waits. Houses, meanwhile, remain at 2.6 months: whoever sells a condo to buy a house in Sainte-Thérèse sells in the slowest market and buys in the fastest. Sell first, or negotiate an offer conditional on the sale, and do not count on the condo's appreciation to cover the gap (from condo to house in Sainte-Thérèse).
How to read these figures
Two measures from the same Centris query, same settings: Condominium category, whole municipality, by month over ten years, then aggregated by year. Inventory is a month-end snapshot averaged over the year; new listings are a flow added over the year. A condo withdrawn and relisted counts twice in the flow and once in the snapshot. 2026 stops in September: the annual pace of new listings is a rule of three, not a forecast. The months of inventory for houses come from the homes-for-sale page in Sainte-Thérèse, harvested September 30 with the same settings.
