How to Choose a Residential Real Estate Agency in Westmount

Which agency is the right one for a Westmount purchase? The honest answer starts with a different question: what are you buying? A condominium, a single-family house and a plex behaved so differently in the second quarter of 2026 that the broker who reads one segment well may barely read another. Segment-specific knowledge is the credential that matters, and the first place it shows up is in how an agency handles neighbourhood-level numbers.

One quarter, three different markets

Across the Montreal census metropolitan area, 13,365 residential properties changed hands in the second quarter of 2026, down 7% from a year earlier. That single figure hides three stories moving in different directions.

Single-family homes reached a median of $645,000, up 3% year over year, and sold in an average of 32 days, three days faster than last year. Condominiums held nearly flat at a $430,000 median, up 1%, but took 48 days to sell, six days slower. Plexes of two to five units carried the highest median at $874,000, up 5%, and sold in 43 days, six days quicker than a year ago.

Sales volume told a diverging story of its own. Condo transactions fell 10% while single-family fell 6% and plex sales eased 5%. Same quarter, same region, opposite signals.

Why a regional average can mislead an offer

Westmount is not the Montreal metro, and the metro median is not a Westmount price. A $645,000 regional median for single-family homes sits far below what most Westmount houses trade at, and a buyer who anchors to the wider figure will misjudge both the opening offer and the room to negotiate.

A metro-wide median answers a metro-wide question, not the one a buyer asks about a specific street.

This is where borough-level and street-level data earns its place. An agency that can show recent comparable sales on the actual blocks in play, rather than a press-release headline, gives a buyer something to price against. A large share of Aguinaga's transaction work involves plexes, and he works frequently with first-time buyers and on military and relocation files, so the neighbourhood reads come from files worked rather than a regional summary.

What to look for, by segment

A condominium buyer should press on absorption and timing. With condo days on market rising to 48 and sales down 10%, pricing strategy in a softening segment is the live question, and a good broker will explain how long comparable units are sitting before quoting a number.

A single-family buyer should ask for neighbourhood pricing and a frank read on both the school catchment and the work the house needs. The 32-day average masks fast-moving, well-priced listings sitting next to slow, mispriced ones on the same street.

A plex buyer is really buying an income stream. The math on rents and turnover cost decides whether an $874,000 building is a fair price or a stretch, and that analysis looks nothing like pricing a house.

How to interview an agency

Volume claims are generic. A sharper question is how many of a broker's last several transactions were in the buyer's own segment and neighbourhood. Another is who actually handles the negotiation once an offer is in. A third is whether the agency can show data beyond the quarterly metro press release.

The financing backdrop is the same for everyone. The Bank of Canada policy rate sat at 2.25% in August 2026, and the New Housing Price Index for the Montreal area stood at 159.4 in April, on a 2016 base of 100. What differs from one buyer to the next is which segment those conditions land on, and how well the agency in front of them reads it.

Segment the search, then segment the agency

Active listings across the metro averaged 20,735 in the quarter, up 14% from a year earlier, so buyers have more to choose from and more need for a broker who can tell a fair price from an optimistic one. A Westmount buyer already narrows the search by property type and street. The agency search deserves the same discipline: match the broker to the segment, and ask to see the numbers behind the advice.
