How to read these figures
Every line comes from the same Centris (Matrix) series as our city pages: median sale price and sales of single-family houses and condominiums by year (September 16, 2026 query), median days on market (September 29 query), new listings and inventory (September 30), sold-to-asking ratio (September 30), expired listings (October 1), whole municipalities; 2026 counts January to September. The monthly payment assumes 20% down, 25 years and the 2026 average contracted rate (4.14%), before taxes and insurance. The condo is shown only if the city has at least 20 sales in 2026. Months of inventory divide active listings by the month's sales; under 4, a seller's market, above 6, a buyer's market.
