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

How much is a house worth in Rosemère in 2026?

In Rosemère, the median price of a single-family home was $877,722 over the last four quarters, from October 2025 to September 2026, up 10% over one year, according to Centris statistics, for 141 sales. For the third quarter of 2026 alone, with 26 sales, Centris publishes no median, nor does it for condominiums or plexes: too few transactions.

A median splits sales into two halves; it does not tell you what your house is worth. A 1965 house that has kept its original windows and a renovated house on the Rivière des Mille Îles enter the same calculation, and out of 141 sales, a few more large properties in the year are enough to shift the median.

The price of yours depends on the sector, the living area, the renovations, the lot and its trees. Your new 2027 assessment notice does not measure it either.

How I evaluate a house in Rosemère

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 I add the area’s expired or withdrawn listings: they show the price the market turned down, and a seller should know it before listing.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 Rosemère, the first adjustment concerns age: according to the 2021 census, 42% of dwellings date from before 1981, including 20% from before 1960, and only 15% from 2001 or later. For a 1975 house, what counts is what has been redone, and when.

A roof redone in 2021, invoice in hand, is defended in dollars in the analysis; an original window or electrical service entrance becomes an argument for the buyer and their inspector. Gather your invoices before we meet, and see the lifespan of a roof and windows.

The lot comes next. Single-detached houses make up 82% of dwellings, and the lot is adjusted like everything else: a deep, sunny lot is not worth the same as a lot in the shade of mature trees that are costly to maintain.

With 141 single-family sales in a year, your sector may lack comparables. I then widen to older sales or to neighbouring cities, such as Lorraine and Blainville, adjusting for the gap between the markets, and the range is wider.

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 $877,722 house in Rosemère

The calculation starts from the median of the last four quarters. The mortgage balance, the interest rate and the fee rate are hypothetical: they show the mechanics without predicting them.

Two lines are deliberately missing: the mortgage discharge, which the notary bills according to their fee schedule, and the municipal and school tax adjustments, apportioned to the day at the date of the deed.

The fee has no rate 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 $877,722, one percentage point is worth $8,777.22, or $10,091.61 with taxes. The calculation is detailed in the broker’s commission in Quebec, and each cost in the real cost of selling a home in Quebec.

Have the penalty confirmed before anything else. With a fixed rate, the lender keeps the higher of three months’ interest and the interest rate differential, which can far exceed the $4,443.75 in the example. Ask for the amount at the planned date, and whether your loan can follow you: the mortgage penalty, with examples.

The Rosemère real estate market in figures

Figures for the third quarter of 2026, July to September, and for the last four quarters, 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 Rosemère. Changes over one year, in days for the selling time. “Not published”: too few sales for a reliable statistic.

Rosemère sells less, but faster. Over one year, house sales fell 17%, the average selling time shortened by 19 days and active listings dropped 15% on average. The median rose 10%, but out of 141 sales, a few more large houses are enough to pull it up.

In the third quarter, 50 active houses for 26 sales in three months, or 8.7 sales a month, give about 5.8 months of inventory. Over twelve months, 45 listings on average for 141 sales, or 11.75 a month, give 3.8. The summer was slower than the year, close to the 6.3 months for the Laurentians in the same quarter.

For condominiums, 22 listings on average for 28 sales in a year make about 9.4 months: a much slower market, on very small numbers. For plexes, 7 sales in a year: only an analysis of the income and of neighbouring sales describes your building.

Value by sector in Rosemère

Centris does not publish statistics by sector in Rosemère: the median brings together the waterfront and Rosemère-Nord, houses from before 1960 and from the 2010s.

On the Rivière des Mille Îles: Bord-de-l’Eau and the Islands sector

A waterfront property is a market of its own: access to the water attracts a specific buyer, the shore, the littoral zone and sometimes the flood zone weigh on the price, and the comparables must be waterfront. Until the new-generation maps are published, those of the municipality or the MRC apply, according to Québec.ca. Ask the planning department in writing what applies to your address, and read buying in a flood zone in Quebec.

Vieux-Rosemère and Grande-Côte

For an older house, character and upkeep enter the adjustments just as the living area does. For a house from before 1960, the range depends on what has been brought up to standard, from the electrical system to the foundations. Near the Rosemère station, on exo’s line 12 Saint-Jérôme, walking distance is part of the adjustments.

The golf sector and Rosemère-Nord

The land of the former golf club, 60 hectares, is the subject of a public file by the City. For a house that borders it, the buyer will ask what could be built there: the answer is in that file and at the planning department. Elsewhere, the best comparables remain on your street.

Rosemère and its neighbours

Your price will be compared with that of the cities around it. Over the last four quarters, according to Centris, the single-family median stood as follows:

Rosemère has the highest median of the six: a neighbouring sale is adjusted before it is used here. The seven cities of the MRC are compared in the real estate market in Rosemère and neighbouring cities, and the city on my page real estate broker in Rosemère.

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?

Rosemère’s new roll: why your 2027 notice is not a sale price

On November 4, 2026, the City published the public notice of the filing of the 2027-2028-2029 roll, which replaces the 2024 to 2026 roll, based on the market of July 1, 2022. Its reference date is July 1, 2025 (Loi sur la fiscalité municipale, section 46): your new notice measures the market of that summer.

For 2026, the median proportion of the old roll was 89%, a comparative factor of 1.12: a house entered at $700,000 corresponded, for a typical house, to a price of around $784,000. For 2027, that of the new roll is 100%, factor 1.00: at the midpoint, the new values represent 100% of sale prices.

This 100% does not make your notice a price. It is a median calculated on the properties sold: yours can be entered above or below its sale price. The Centris median from October 2025 to September 2026 is also 10% higher than that of the previous twelve months, and a mass assessment does not see the kitchen redone last year.

The tax bill cannot be read as a value either: for the 2024-2026 roll, the City had spread the increase over three years, and as of November 11, 2026 its page says nothing about this for the new roll.

To contest, the application for review is filed before May 1, 2027, according to the public notice: contesting your municipal assessment. For a ballpark figure, the online estimator starts from Centris medians. The next roll, for 2030 to 2032, will start from the market of July 1, 2028.

Seven mistakes that cost Rosemère sellers dearly

1. Reading the new assessment notice as a price

It measures the market of July 1, 2025, as a mass assessment, and its median proportion of 100% describes the whole roll, not your address. Listing at that figure can underprice a well-renovated house, or overprice one that is not.

2. Listing “just to see”

In the third quarter, 50 houses were active for 26 sales: the buyer compares. The first look comes with the alert that Centris.ca sends to buyers at listing; a price drop a month later reaches people who have already ruled the house out.

3. Relying on the median or an online estimator

With 141 sales in a year, an algorithm lacks comparables and sees neither the lot nor the renovations. The $877,722 median is a market benchmark, not the price of an address.

4. Transposing a neighbouring sale without adjusting it

Neighbouring sales help out when your sector lacks them, but the median is $773,937 in Lorraine and $762,625 in Blainville, against $877,722 here: a neighbouring sale is corrected for the gap between the markets.

5. Letting the buyer discover the age of the components

With 42% of dwellings built before 1981, the inspector will look for the original roof, the attic insulation and the electrical service entrance. A dated invoice takes away a reason to negotiate; a discovery at inspection adds one. Insulation that looks like vermiculite is tested before listing: vermiculite and asbestos.

6. Arriving with no answer about water

The buyer will want to know whether the basement took in water during the torrential rains of August 9, 2024, to which the City devotes a page. If your house went through the free support against rain-related flooding that Rosemère offers with the MRC, from July 2026 to November 1, 2027, keep the report and the invoices for the work for the sale file.

7. Photos that leave out the lot

Part of what the buyer pays for in Rosemère is the lot, and their first visit happens on Centris.ca. Photos without the garden or the depth of the lot show the house without what sets it apart. Winter has its own rules: selling your house in winter.

When to sell in Rosemère?

No month guarantees a better price, but three dynamics are at play in Rosemère.

Families: according to the 2021 census, 48% of Rosemère families are couples with children at home. For a child to start the year at their new school, the keys are needed before the end of August, so the house has to be found in the spring. A family house listed in March or April arrives when these buyers are searching.

Age: 52% of Rosemère residents are 45 or older, and 41% of families are couples without children at home. These sellers have no school clock; their moment is when the next home has been found. See selling the family home.

Supply: 50 active houses in the third quarter, as a year earlier, and 15% fewer on average over the year. Buyers had a little less choice than a year earlier, which says nothing about 2027.

Your timeline weighs more than the market’s. 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; six months’ lead time leaves time to prepare the house and its documents.

Selling and buying at the same time in Rosemère

This double move has two faces in Rosemère: the family that wants something bigger, and the couple whose children have left. For the latter, the local choice of condos is thin, 28 sales in a year and 19 active in the third quarter: find your purchase before selling.

The order of operations that protects best:

1. Get an evaluation first: the net amount of the sale sets your purchase budget.
2. Sell firm before buying, or buy on condition of selling your house: the condition covers you, but weakens your offer.
3. Make the dates line up: the deed and occupancy are negotiated separately.
4. Talk to your lender about a bridge loan: once the sale is firm, it can advance the down payment for the purchase. Only the lender can confirm it; I do not give mortgage advice.

If you buy again in Rosemère, the welcome tax (property transfer duties) is paid in a single instalment. In 2026, the City applies 3% on the bracket above $500,000: on a base of $877,722, $5,610.50 up to $500,000 at the rates set by law, plus $11,331.66 on the rest, for $16,942.16. The base is the higher of the price and the roll value multiplied by the comparative factor, 1.12 in 2026 and 1.00 in 2027; check the 2027 rates before signing.
