The question is being asked in almost every kitchen across the region: exactly how much is my house worth? Not the value from three years ago, nor the figure on the tax bill. The real one—today’s market value. In 2026, the context is in your favor if you are selling. The latest QPAREB statistics show a South Shore market that remains favorable to sellers, with prices on the rise. Now, this needs to be translated for your specific property, on your street.
Here are the benchmarks, and above all, what makes your specific figure move.
What the Châteauguay market says
Let’s start with the orders of magnitude. In Châteauguay, a single-family home is trading in 2026 within a range of approximately $450,000 to $580,000, according to data compiled from the QPAREB and Royal LePage. Across Quebec, the median price of a single-family home reached $524,900 in May 2026, up 5% year-over-year. On the South Shore, an increase of 3% to 6% is anticipated for the year. These figures set the stage. They do not tell you what your house is worth, because a $130,000 gap hides a reality: between two properties in the same city, everything can change.
The factors that truly determine your price
A broker establishing market value looks at much more than just square footage. First, the location, down to the specific street and the orientation of the lot. Then the general condition of the building, the year of construction, recent renovations, the number and layout of rooms, landscaping, and current market conditions. Two houses that look identical on paper can differ in value by tens of thousands of dollars based on a replaced roof, a finished basement, or proximity to a sought-after school. This is the comparative analysis method: your property is compared to similar properties recently sold in the area, and then each difference is adjusted in dollars.
Why online estimates are wrong
The free tool that displays an amount in thirty seconds has one merit: it gives an order of magnitude. It also has a major limitation: it has never seen your kitchen. It works on averages and ignores the actual condition, renovations, and unique features that create your value. The same applies to the municipal assessment, which reflects the market approximately 18 months before it comes into effect and is used to calculate taxes, not to set a sale price. Relying on either means accepting a margin of error that can amount to tens of thousands of dollars. The only way to obtain a reliable figure remains the analysis of a broker who knows your area, which is what a free, no-obligation evaluation of your property offers you.
