Ask three people how the Lake County market is doing right now, and you'll get three different answers — and all three might be right. The overall countywide numbers tell a clean story: tight inventory, rising prices, sellers still holding the cards. But break the market into its three real segments — detached homes, condos and townhomes, and luxury — and the picture splits in ways worth knowing before you make a move.

Here's what the data actually shows, segment by segment, based on the latest 12-month trailing numbers through July 2026.

The single-family market — every price point combined — stayed firmly in seller's-market territory. Median price climbed to $407,000, up 5.7% year-over-year, with price per square foot up nearly 7% to $218.

Inventory is the real story. Active listings fell 4.1% year-over-year to just 1,090 homes, pushing months of supply down to 1.6 — well below the 4–6 months that would signal a balanced market. Homes are moving fast, too: an average of 39 days on market, selling at 100.1% of list price. Buyers are largely paying full asking price just to compete for what's available.

What this means: if you're shopping for a detached home in Lake County, expect competition, and expect to move quickly and cleanly when the right listing appears.

The attached-home segment told a more moderate story. Median price rose 4.0% to $300,000, and price per square foot gained 4.7% to $201 — solid, but softer gains than the detached market.

Closed sales dipped 4.9% and new listings slipped slightly too, though inventory held fairly steady at 236 active listings and 1.4 months of supply. Homes in this category took a touch longer to sell — 35 days on average — and buyers pulled back marginally on offers, with the average sale landing at 99.4% of list price. Still a healthy number, but a reminder that attached properties aren't seeing quite the same bidding intensity as single-family homes.

What this means: condo and townhome buyers have a bit more negotiating room here than anywhere else in the county right now.

The luxury segment was the standout this period. Closed sales jumped 14.8% year-over-year to 1,727, and new listings rose 9.6% to 2,813 — both buyer demand and seller confidence are building at the high end.

Despite that surge in new inventory, months of supply actually fell 17.2% to just 2.4 months, because sales are absorbing it that quickly. Average market time dropped 14.3% to 48 days, and luxury buyers are paying the highest premium of any segment tracked, with the average sale price hitting 100.8% of list.

What this means: the $720K+ market isn't just a starter-home story that scales up anymore — it's accelerating in its own right.

Taken together, these numbers paint a picture of scarcity driving urgency across every price point in Lake County — but the pressure looks different depending on where you're listing. If you're selling a detached home, timing remains excellent: fast sales, full-price offers, minimal days on market. Condo and townhome sellers are still in a strong position, just with slightly more give on price. And luxury sellers are watching a market that's quietly become one of the most competitive in the county.

For buyers, patience and preparation matter more than ever — especially in the segments where competition is heating up fastest. Detached-home buyers need financing in order and offers ready to move within days, not weeks. Condo and townhome buyers have a little more room to negotiate on price and terms. And buyers in the luxury tier should expect real competition for the first time in a while — this is no longer a market where a slow, deliberate search gets you the house you want.

There isn't one Lake County market right now — there are three, moving at three different speeds. Wherever you're shopping or selling, the segment you're in matters as much as the county you're in.

Is Lake County a buyer's or seller's market in 2026?
It depends on the segment. Single-family homes remain firmly in seller's-market territory with just 1.6 months of supply. Condos and townhomes are also seller-favored but with more breathing room at 1.4 months of supply and buyers landing closer to list price. Luxury homes ($720K+) have tightened significantly this year, with months of supply down to 2.4 as buyer demand accelerates.

Why is the condo market different from the single-family market?
Attached homes have seen more modest price growth, slightly longer market times, and buyers paying closer to (or occasionally under) list price. It's still a strong market for sellers, just without the same bidding intensity as detached homes.

Is the luxury market in Lake County actually getting more competitive?
Yes. Closed sales in the $720K+ tier are up nearly 15% year-over-year, and despite significantly more new listings hitting the market, months of supply still fell because buyers are absorbing that inventory quickly.

What does "months of supply" actually measure?
It's how long it would take to sell through all current active listings at the current sales pace, assuming no new listings came on the market. Four to six months is generally considered a balanced market; below that favors sellers, above it favors buyers.

Where does this data come from?
All figures are pulled from MRED InfoSparks, the regional MLS covering Lake County, Illinois, on a 12-month trailing basis through July 2026.

Whether you're buying a detached home in a tight, fast-moving market, shopping condos with a little more room to negotiate, or navigating the luxury tier's sudden acceleration, the right strategy depends on which of these three markets you're really in.
