Montreal's 10% Sales Drop: Which Side of the Adjustment Phase Are You On?

Nathalie owns a duplex in Rosemont-La Petite-Patrie that she bought in 2021 at 1.92% on a five-year fixed. Her term renews in March 2027, and the current best rate she can find is 4.68%. Her mortgage balance is $410,000. On paper, she's looking at a monthly payment jump from $1,740 to roughly $2,380, $640 more every month, or $7,680 annually. She's thinking about selling before the renewal hits.

Kevin has been renting a 3½ in Verdun since 2023 at $1,475/month. He has $68,000 saved, pre-approved at 4.65%, and he's been watching listing counts climb every week on Centris since May. In July, active inventory in the Montreal CMA was up 22% year-over-year. For the first time since 2020, Kevin isn't competing against six other offers on a Sunday afternoon.

The Quebec Professional Association of Real Estate Brokers recorded a 10% drop in total residential transactions in July 2026 compared to the same month a year earlier. That's not a crash. It's a stall. The people who need to sell can't get their number. The people who want to buy are waiting for the floor.

The Rate-Lock Paralysis

Nathalie's situation is structural, not unique. Roughly 40% of Canadian mortgages were written between 2020 and 2022 at sub-2.5% rates. Many of those terms expire between late 2026 and mid-2027. The payment shock on a $400,000 balance moving from 2% to 4.7% is $621/month. On a $600,000 balance, it's $932.

The standard advice is to sell before renewal if the payment increase forces you into financial stress. The real calculation is narrower: sell if the difference between your locked-in rate and the new rate costs more than the transaction friction of selling and moving. For Nathalie, selling costs are roughly 5% of sale price (realtor commissions, notary, land transfer tax if she re-buys). On a $575,000 duplex, that's $28,750 in friction. Her payment increase over five years is $38,400. She clears the threshold.

Kevin, on the other hand, has no rate to protect. His scenario flips when supply rises enough to shift negotiating leverage. In July, the median time a single-family home sat on the market in Montreal before selling was 58 days, up from 31 days in July 2023. Longer days-on-market means asking prices soften, conditional offers get accepted, and inspection contingencies stop killing deals.

Where the Market Actually Moved

The 10% sales drop wasn't uniform. The Island of Montreal saw transactions fall 12%, while the North Shore dropped only 7%. The South Shore, which exploded during the work-from-home rush of 2021-2022, posted an 11% decline. Condo sales fell harder than single-family homes, down 13% versus 9%, because condos are the entry-level product and first-time buyers are the segment most sensitive to rate changes.

Plexes, Montreal's signature 2-to-5 unit buildings, held steadier. Sales dropped just 8%. Why the resilience? Plex buyers are often small-scale investors or owner-occupiers who live in one unit and rent the others. Rental income offsets the mortgage payment, which makes the sticker shock of a 4.7% rate easier to absorb than it is for a pure owner-occupier.

The Stalemate Condition

Price stickiness is the other half of the adjustment phase. Sellers in Montreal historically resist listing at a loss. The median price for a single-family home in July was $548,000, down just 1.8% from July 2025. Volume collapsed, but prices barely moved. That gap is the stalemate: buyers waiting for capitulation that hasn't arrived, sellers waiting for a rebound that isn't coming.

This resolves in one of two ways. Either mortgage rates drop meaningfully, call it sub-4%, and the sideline buyers flood back in, or enough sellers hit a forcing event (job loss, divorce, estate settlement, renewal they can't afford) and listings convert to sales at lower clearing prices. Neither has happened yet.

For Nathalie, March 2027 is the forcing event. For Kevin, it's whenever the median days-on-market hits 75 and he stops feeling like he's buying the top.
