The Number Every Westmont Homeowner Should See

The trailing 12-month median sale price for a detached single-family home in Westmont is now $461,500 — up 11.8% compared to the same period a year ago. That's not a seasonal blip. That's a sustained, measurable shift in what buyers are paying for homes in this market.

At the same time, inventory of detached homes dropped 30.8% year over year. Attached homes — condos and townhomes — saw inventory fall an even sharper 44.4%, while their median price jumped 17% to $330,000. When prices rise and supply shrinks simultaneously, the window for sellers opens wide. The question is how long it stays that way.

Why Inventory Is the Story Right Now

Sellers often focus on price — understandably. But the real leverage in this market comes from the supply side. With only 9 detached homes available at month end and 5 attached units, Westmont buyers are competing for a very small pool of options. That competition is what drives list-to-sale ratios above 100% and compresses days on market.

When a well-priced home hits the market in a low-inventory environment, it doesn't sit. It generates activity immediately. That's the dynamic Westmont sellers are working with right now — and it won't last indefinitely as more listings come online later in the year.

What 100.7% List-to-Sale Actually Means

A list-to-sale ratio above 100% means buyers are paying above asking price on average. That's not just a data point — it tells you that demand is outpacing supply enough for buyers to compete against each other. For a seller, it means pricing at market isn't leaving money on the table; in many cases, it's triggering a bidding situation that pushes the final number higher.

Why Pricing Precision Matters More Than Ever

A rising market creates a trap that catches sellers more often than you'd expect: overpricing. It sounds counterintuitive — prices are going up, so why not push the number? Because buyers in 2026 are informed. They're watching the same data their agents pull. An overpriced home doesn't generate competing offers; it generates skepticism. And the longer it sits, the more negotiating power shifts from seller to buyer.

The goal is to price your home where it generates immediate, strong interest from multiple buyers. That requires knowing what the market is actually doing right now — not relying on a Zestimate from six months ago or a neighbor's sale that doesn't reflect your home's specific features.

The Spring Window Is Open — But It Won't Stay That Way

Spring is historically the strongest seller's market in the Chicago suburbs. Buyers who waited through winter are active and motivated. With Westmont inventory at multi-year lows, the competition a seller faces from other listings is minimal right now. That combination — motivated buyers, almost no competing supply — is exactly the environment where well-priced homes move quickly and at strong numbers.

As the year progresses, more inventory will come to market. The advantage sellers have today will narrow. If you're considering selling your Westmont home, the market data says the window is open right now.
