How to Choose a Residential Real Estate Agency in Longueuil

How to Choose a Residential Real Estate Agency in Longueuil

What should a Longueuil buyer ask before signing with an agency? The honest answer depends on what they are buying. A condo purchase and a plex purchase in the same month call for different questions, because the market underneath them is moving in different directions.

The market is not one market

Across the Montreal CMA in the second quarter of 2026, residential sales came to 13,365 transactions, down 7% from a year earlier. That single figure hides three very different stories.

Condominiums cooled. Sales fell 10% year over year, and the average condo took 48 days to sell, six days longer than the year before. Single-family homes held firmer. Sales slipped 6%, but the median rose to $645,000 and the average sale closed in 32 days, three days quicker than a year ago. Plexes of two to five units told a third story again, with the median reaching $874,000, up 5%, and selling time falling to 43 days.

Same quarter, opposite signals. An agency that treats all three the same way is reading one number where there are three.

The right first question is not how many years an agency has been open, but how much of its recent work sits in the exact segment and neighbourhood you are buying in.

Prices moved at three different speeds

Price direction split the same way selling speed did. The condo median rose 1%, the single-family median 3%, and the plex median 5%. A buyer who anchors an offer to a general sense that Montreal prices are up a few percent can misjudge any of the three.

These are CMA-wide medians, which shapes how a Longueuil buyer should use them. A regional median blends the whole census metropolitan area, from downtown condo towers to off-island single-family streets. The number that should shape an offer is the one for the buyer's property type on the buyer's streets, and that number can sit well above or below the regional line.

Why borough-level data changes the offer

Consider the gap between the $645,000 single-family median and the $874,000 plex median. A buyer comparing two listings priced near each other cannot tell from the CMA figure alone whether either is fairly priced for its own micro-market. Borough-level and neighbourhood-level sale data closes that gap. It shows what comparable homes on comparable streets have been accepting and how long they sat before an offer landed.

This is where segment-specific work earns its keep. A large share of Aguinaga's transaction work involves plexes, and he works frequently with first-time buyers as well as on military and relocation files. That kind of concentration is what lets a broker say not just what the median is, but what a specific street has been doing lately and where a given asking price sits against it. Regional aggregates cannot answer that. Recent, local, type-matched sales can.

The wider inventory backdrop makes the point sharper. Active listings across the CMA averaged 20,735 over the quarter, up 14% year over year. More choice generally hands buyers more room to negotiate, but that room is not evenly spread. It is widest where a segment is cooling and days on market are climbing, and narrowest where homes are still selling inside a month. Only local data tells a buyer which side of that line their target property is on.

What to ask, by segment

For a condo, ask how the agency reads absorption and days on market in a softening tier, and how it would price to sell without leaving money on the table. For a single-family home, ask for borough-level comparables and school-catchment detail, along with a frank read on any work the property needs. For a plex, ask how the broker checks the rent roll and runs the income math before an offer goes in.

Then ask the question that cuts across every segment: of the agency's last ten transactions, how many were in this property type and this area? Volume alone is generic. A record concentrated in the buyer's segment and neighbourhood is the credential that maps to the data above. Rate movements form part of the backdrop too, with the Bank of Canada policy rate at 2.25% as of August 2026, but the rate is the same for everyone. Local knowledge is not.

Segment the agency search the same way you segment the home search

A buyer narrows the home search by property type, area and budget without thinking twice. The agency search deserves the same filter. The broker who can show recent, local, type-matched numbers for the property in question is the one positioned to price it and offer on it well. That is a test any buyer can apply, whichever agency they end up choosing.
