Two years ago, you could easily find houses in Brossard under 450k. Today? That's a fantasy. And it's not just about interest rates or general inflation. There are concrete mechanisms that explain why the factors behind local real estate price increases have accelerated on the South Shore.

I'll be straight with you: the real estate market has changed the rules of the game. And if you understand why, you'll negotiate better, whether you're buying or selling.

Inventory that's disappearing: the real battleground

Spring inventory availability in Longueuil has collapsed. In 2022, we had 2 to 3 months of inventory. Now? Barely 1 month. When people have fewer choices, sellers set the prices.

Why is inventory so tight? Because fewer houses sell at lower prices, fewer owners decide to sell. It's a vicious circle that benefits current sellers.

New construction vs used homes in Brossard: two different universes

Here's an important distinction: new construction vs used homes in Brossard tells two different stories. New condos and isolated new homes sell directly between developer and buyer, without immediate market pressure.

Used homes? They're trapped in the market. And as used home inventory shrinks, used home prices climb faster than new ones. A concrete example: a used home in Saint-Lambert in 2021 was worth 520k. Identical in 2024? 625k. A new one? It climbs slowly, more predictable.

Low inventory doesn't just create a shortage—it creates a psychology of urgency. Buyers pay faster, negotiate less.

The exodus from Montreal to the South Shore: the real demand

Brossard, Longueuil, and even Boucherville have become attractive for one simple reason: more space for the same price as Montreal. A duplex at 550k in Longueuil? In Plateau-Mont-Royal, you find a cramped little 2.5.

The pandemic accelerated things, but now it's structural. Families working from home one day a week want space. Pool, yard, double garage. That exists on the South Shore. It's a factor behind local real estate price increases that people often forget: sustained growing demand.

Mortgage rates and their real impact (spoiler: less than you think)

Yes, rates went up. But that's not the main explanation for rising prices. If it were, prices should drop when rates fall—but that's not how it works.

Rates impact borrowing capacity, so they create play in prices (less potential competition). But they don't explain a 20% increase in two years. Inventory does the heavy lifting.

Where does this go? What you need to expect

If rates actually drop—and that's a big IF—inventory will loosen up a bit. More people will feel capable of buying and selling. But it won't crash prices. It'll just balance the market.

For you, buyer: accept that you're buying in a seller's market. Get serious about inspection reports. For you, seller: you still have the advantage, but it's shrinking. List your home before inventory really picks up.

The factors behind local real estate price increases won't disappear tomorrow. But understanding them already puts you two steps ahead.
