Free evaluation of your home in Blainville: its market value, and what you will keep after the sale

How much is a house worth in Blainville in 2026?

In Blainville, the median price of a single-family home was $835,000 in the third quarter of 2026, up 11% over one year, according to Centris statistics. Over the last four quarters, the median stands at $762,625 for 646 sales. For condominiums, it is $432,425 over the same period.

A median splits sales into two halves. It does not tell you what your house is worth. A single quarter can also be pulled by the mix of sales: if more large houses change hands during the summer, the median rises without any house having gained value. The $72,375 gap between the quarterly median and the four-quarter median calls for this caution.

What sets the price of yours: the sector, the living area, the year built and the age of the renovations, the lot, the garage, the basement, the pool. The free evaluation starts from these elements, not from the city average.

How I evaluate a house in Blainville

Georges Matar

Trained as a biomedical engineer, member of the Ordre des ingénieurs du Québec, holder of a doctorate. Residential real estate broker, OACIQ licence J7941, RE/MAX DU CARTIER INC., real estate agency.

Before brokerage, I spent about ten years in scientific research, taught for eight years in a faculty of engineering and was regional manager of biomedical engineering in Nunavik. One habit stayed with me: a figure given without its margin of error means nothing. A home evaluation is a measurement. I treat it as one.

1. I choose the comparables. Recent sales, as close to your home as possible, of the same type and similar age. I add the area’s expired or withdrawn listings: they show the price the market turned down, and a seller should know it before listing.
2. I adjust each comparable for what sets it apart from your property: living area, year built, renovations and their age, lot, garage, finished basement, pool, distance from the train station or the highway. Every adjustment is written down, in dollars. You can discuss it line by line.
3. I measure the spread. Once adjusted, comparables never land on the same price. The gap between them, the standard deviation for engineers, tells you how reliable the range is: three sales within $10,000 of each other do not tell the same story as six sales spread over $80,000.
4. I give you a range, not a flattering number. The strategic list price and the probable sale price are two different things. I show them side by side, with what could move one or the other.

This is a comparative market analysis prepared by a real estate broker, not a chartered appraiser’s report. It is meant to help you decide whether selling is worth it, when, and at what list price.

In Blainville, the age of the housing stock weighs heavily in the adjustments. According to the 2021 census, 49% of the city’s dwellings were built between 1991 and 2010, and 30% between 1961 and 1990. A house built in 1996 is 30 years old: the buyer and their inspector will look at the age of the roof, the windows, the heat pump and the French drain. Every original component becomes a negotiating argument.

Two neighbouring houses of the same model can therefore sell at prices far apart, depending on what was redone, and when. That is why every adjustment is written in dollars in the analysis.

The type of house also counts. Single-detached houses make up 69% of Blainville’s dwellings, and 78% of households are owners. A buyer there first compares detached houses with one another; a semi-detached or a row house, 7% of the stock, is compared within its own group, with fewer sales to back it up.

What your free evaluation includes

Comparable sales in your area

Three to six properties similar to yours, sold in the last six months when there are enough sales, further back otherwise, and I then tell you why. For each one: its listing sheet, sale price, time on market, and what brings it closer to or sets it apart from your home.

The price range

Two figures side by side: the list price I would recommend and the probable sale price. The gap between them is the negotiating margin buyers in your area obtained on recent sales, measured by the difference between asking price and price paid.

The net amount after the sale

The probable price, minus your mortgage balance, the prepayment penalty if any, the broker’s fee and its taxes, the mortgage discharge at the notary and a new certificate of location if yours is out of date. This is the figure that decides a plan. Good news on the price can vanish into a penalty nobody asked the lender about.

The three improvements that pay off most, and the ones not worth doing

A short list, specific to your home: what takes away a reason for the buyer to negotiate (a visible repair, a missing document, a poorly presented room) and what would cost you more than you would get back. No generic renovation list.

For a condo: reading the co-ownership file

Declaration of co-ownership, minutes of the latest meetings, contingency fund statement and fund study, building by-laws: I read them before setting the price. The buyer and their notary will read them too, and a special assessment announced in the minutes always ends up being paid in the price. I hold the Coproprié-T certification in co-ownership law.

Example: what is left after selling an $835,000 house in Blainville

Here is the calculation for a house sold at the median price of the third quarter of 2026. The mortgage balance, the interest rate and the fee rate are hypothetical: they serve to show the mechanics, not to predict them. In your evaluation, each line is calculated with your figures.

Two lines are deliberately missing. The mortgage discharge, which your notary prices according to their fee schedule. And the municipal and school tax adjustments, calculated to the day at the date of the deed, which work in your favour if you have already paid for the year.

On the fee: no rate is set by law or by the OACIQ. It is negotiated, as a percentage or as a flat amount, and is written into the brokerage contract. On $835,000, each percentage point represents $8,350, or $9,600.41 with taxes. The full mechanics are in the broker’s commission in Quebec, and each cost in the real cost of selling a home in Quebec.

The penalty is the line to have confirmed first. With a fixed rate, the lender takes the higher of three months’ interest and the interest rate differential, which can cost much more than in the example. Ask for the exact amount for the planned sale date, and ask whether your loan can be transferred: the mortgage penalty, with examples.

The Blainville real estate market in figures

Figures for the third quarter of 2026, July to September, taken from Centris on November 11, 2026. They will be replaced by those of the fourth quarter in mid-January 2027.

Source: Centris real estate statistics for Blainville. Changes compare with the same period one year earlier. Centris does not publish a median when the number of sales is insufficient for a reliable statistic.

What these figures mean for a seller, in plain words. Demand is holding: single-family sales rose 8% in one year, and the median price 11%. But buyers have more choice than in 2025: 174 active house listings during the quarter, and an average 17% higher over the last four quarters. A buyer therefore compares your house with more houses, and a badly set price gets noticed faster.

A simple calculation measures it. 174 active listings for 148 sales in three months is about 3.5 months of inventory at the summer pace. For condominiums, 51 listings for 28 sales gives about 5.5 months. The Blainville condo is a slower market than the house: 49 days of average selling time over one year, against 30.

In early July 2026, I visited a condo in Blainville with buyers. The unit was superb; the management of the co-ownership, much less so: no up-to-date contingency fund study, no maintenance logbook. I explained to my clients what that meant. The logbook records what has been maintained in the common portions and what will have to be redone over 25 years; the study puts a figure on what the fund must hold to pay for it. Without them, no one knows whether the fund will be enough on the day the roof or the windows need redoing. And if the first study finds the fund insufficient, the board of directors must raise contributions, with at most 10 years to replenish it: higher condo fees, or even a special assessment, paid by whoever just bought.

Bill 16 gives syndicates until August 2028 to obtain their first logbook and their first study. But since August 14, 2025, the seller must give the buyer the syndicate’s attestation on the condition of the co-ownership: the fund balance, the amount recommended by the most recent study, the work planned over 10 years. A poorly managed co-ownership is therefore visible before signing, and a well-advised buyer takes it into account in their offer. If you are selling a condo in Blainville, ask your syndicate for the attestation before listing: it has 15 days to provide it. The details are in what Bill 16 requires you to check.

For plexes, caution: 44 sales in a year is too few for the $821,562 median or the 12-day selling time to describe your building.

Value by sector in Blainville

Centris does not publish statistics by sector within Blainville. The $835,000 median therefore mixes Fontainebleau and Chante-Bois, houses from 1975 and from 2015. That is why the analysis starts from sales in your sector, not in the city.

Fontainebleau

A planned sector, with larger properties and stricter architectural requirements than the rest of the city. The buyer pool there is narrower: comparables must come from Fontainebleau itself, and the price is defended on living area, construction quality and upkeep. With fewer buyers at this budget, a poorly presented house is less likely to find its buyer quickly.

Chante-Bois and Notre-Dame

The family core of Blainville: houses from the 1980s to the 2000s, residential streets, schools nearby. Houses from similar periods and of similar size, which gives many comparables and a tighter range. The gap between two houses there comes down mainly to the age of the renovations: roof, windows, kitchen, bathrooms, basement.

The Domaine Vert area, Blainville-Est and Plateau Saint-Louis

Proximity to the regional park is a concrete selling point for part of the Domaine Vert’s buyers; it is shown in the photos and the description, not only in the price. Elsewhere in the city, the same rule applies: the best comparables are on your street and the neighbouring streets, of the same type and similar age. For a house near Blainville’s exo station, on the Saint-Jérôme line, walking distance is part of the adjustments.

Blainville and its neighbours

A buyer looking in Blainville may also look at the surrounding cities, and your price will be compared with theirs. Over the last four quarters, according to Centris, the single-family median stood as follows:

The seven cities of the MRC are compared in detail in the Blainville, Sainte-Thérèse and Boisbriand real estate market, and the city itself on my page real estate broker in Blainville.

How it works

1. 1. You enter the address 1 minute

   The form starts with the address. Your expected selling time and your contact details cover the rest; “just exploring” is a valid answer.

2. 2. A ten-minute call Within 24 hours

   I ask the questions the data cannot answer: renovations, known issues, what you plan to do next. If you don’t like the phone, we do it by text.

3. 3. The analysis, at your home or by video On the date that suits you

   I present the comparables, the range and the net amount. A visit makes the analysis more precise, because condition and renovations do not show up in the data. It is not required for a first range.

4. 4. A marketing plan, only if you want one On request

   List price, preparation, timeline, documents to gather. If you don’t ask for it, we stop at step 3.

Municipal assessment, chartered appraiser, online estimator or broker’s analysis: which one do you need?

Why Blainville’s assessment roll is far from the market price

The assessment roll in force in Blainville covers 2025, 2026 and 2027. The law sets its reference date at July 1, 2023: your assessment notice measures the market of that summer, not today’s (Loi sur la fiscalité municipale, section 46).

The government measures the gap every year. For 2027, the median proportion of Blainville’s roll is 90%, against 96% in 2026: at the midpoint, the values entered on the roll represent 90% of sale prices, a comparative factor of 1.11. A house entered on the roll at $600,000 thus corresponds, for a typical house, to a price of around $666,000. Yours can stray from it in either direction: the median proportion describes the roll as a whole, not an address.

The next roll, for 2028 to 2030, will start from the market of July 1, 2026. If it is your tax bill that worries you, that is a different process: contesting your municipal assessment. For a first ballpark figure, the online estimator starts from Centris medians.

Seven mistakes that cost Blainville sellers dearly

1. Listing “just to see”

With 174 active house listings last quarter, the buyer compares. A house listed above its comparables mostly serves to make the others look reasonable. The first weeks, when buyers and their brokers receive the Centris.ca alert, are when the listing gets the most attention; a price corrected a month later does not win back that first look.

2. Taking the municipal assessment for a price

It measures the market of July 1, 2023, and the Quebec government puts it at 90% of sale prices for 2027. Using it to set a price means starting from a figure that is more than three years behind.

3. Renovating the wrong thing

I advise against redoing a kitchen to your own taste just before selling: the buyer pays for their own taste. In a 1995 house, their inspector will first look at the roof, the windows, the French drain and the electrical service entrance. Before spending, ask yourself which repair takes away a reason to negotiate. See what you get back, and what you don’t.

4. Neglecting the photos

The first visit happens on Centris.ca, not in your living room. Dark photos, or photos taken with a phone, make a Chante-Bois house look less well kept than it is, and the buyer does not come.

5. Forgetting the certificate of location

A pool, a shed, an extension or a fence added since the last certificate: you need a new one, and a land surveyor’s turnaround can exceed several weeks in a busy period. Order it as soon as the decision to sell is made. For a pool, also check that its enclosure complies with the residential pool safety regulation.

6. Putting a condo up for sale without its file

A Blainville condominium stays on the market 49 days on average. A careful buyer asks for the minutes, the contingency fund statement and the fund study; if they arrive a week after the offer, the buyer has a week to have doubts. Gather them before listing.

7. Buying before selling, without a safety net

Signing a promise to purchase without a sale condition means betting that your house will sell on time and at the expected price. If the bet is lost, that means two mortgages. The section on selling and buying at the same time explains the order of operations.

When to sell in Blainville?

No month guarantees a better price. Two dynamics are still at play in Blainville.

The first has to do with families. According to the 2021 census, 48% of Blainville families are couples with children at home. A family that wants to change schools at the start of the school year has to sign at the notary in July or August, and therefore search in the spring. A family house put on the market in March or April reaches these buyers when they are searching.

The second has to do with supply. Active house listings rose 17% on average over one year: the more houses there are for sale, the more the list price counts, whatever the season. Selling in winter can be done too, with its own rules: selling your house in fall or winter.

Your personal timeline weighs more than the calendar: a purchase to coordinate, child custody, a job that changes. The form asks whether you are thinking of selling within 3 months, in 3 to 6 months, in 6 to 12 months, or whether you are just exploring. An evaluation done six months ahead leaves time to take care of the certificate, the small repairs and the order of operations.

Selling and buying at the same time in Blainville

It is the classic case in a family city: you sell a first house for a bigger one, or you move from the house to a condo once the children have left. In both cases, the risk is the same: two notary dates that do not line up.

The order of operations that limits this risk:

1. Get an evaluation first. The net amount of your sale sets your purchase budget; without it, you are shopping blind.
2. List your house before signing a firm purchase, or buy with a promise conditional on the sale of your house. The condition protects you, but it makes your offer weaker than that of a buyer with no condition.
3. Align the dates. The deed date and the occupancy date are both negotiated, and a gap of a few days can be settled with an occupancy after the sale.
4. Talk to the lender about a bridge loan. Once your sale is firm, it can advance the down payment for the purchase while you wait for the sale proceeds. It is up to the lender to confirm it: I do not give mortgage advice.

If you buy again in Blainville, plan for the welcome tax (property transfer duties). The City lowered the rate on the $500,000 to $750,000 bracket to 1.5% in its 2026 budget; according to the example published by the City, an $850,000 house pays $12,360.50 in 2026. The rules are in the welcome tax in Quebec, and the clauses in selling before buying.
