U.S. Housing Market Snapshot
| Median Sale Price | Pending Sales | Active Listings | Days on Market | Buyer-Seller Balance |
|---|---|---|---|---|
| $398,596 (+2.2% YoY) | 336,973 (-1.3% YoY) | 1,534,918 (+2.7% YoY) | 50 days (0 days YoY) | Sellers outnumber buyers by 57.9% |
Nationally, prices rose about 2% and pending sales fell about 1%. Lake County outperformed on both metrics—local prices grew more than twice as fast, and pending sales held slightly positive at 0.8%. Inventory expanded 6% locally versus about 3% nationally, but the county’s 2.4 months of supply remained well below the national figure of about 4. The above-list rate of about 40% still far exceeded the national figure of about 24%, confirming that Lake County was materially more competitive than the U.S. average.
“The U.S. housing market faced some hurdles in August, as inflation and an AI-fueled economy kept mortgage rates high and weighed heavily on homebuyers, sellers, and investors,” said Chen Zhao, Redfin’s head of economics research. “Until recently, affordability and activity had been slowly improving for months, helping the market recover. But now, economic uncertainty and rising prices are keeping more people on the sidelines and slowing the market further. For buyers who need to buy, now is a great time because there’s less competition and a bit more inventory—for sellers, pricing competitively is key to attract attention.”
Lake County Prices Grew More Than Double the National Rate
The median sale price in Lake County reached $428,566 in August, up 4.4% year over year, while national prices rose just 2%. The median price per square foot climbed 5.2% to $225, a faster rate than the headline price increase, suggesting that smaller or more affordable properties grew even more sharply. Lake County has priced above nearby DuPage on a per-home basis by about $20,000 less, but on a per-square-foot basis the gap was tighter.
Price reductions affected 13.9% of active listings—modest by national standards. The typical home sold for 99.9% of its list price, essentially at asking. Sellers no longer commanded premiums on average, but they also rarely needed to discount. The sale-to-list ratio rose 0.3 points from a year ago, a small but positive signal.
Sales Volume Grew 6% While National Transactions Fell
Homes sold in Lake County rose 5.9% year over year to 869, while national sales were roughly flat. Pending sales edged up 0.8%, a modest but positive figure in a national environment where pending activity dropped about 1%.
Active listings climbed 6% to 3,039, and new listings surged 10.6% to 920. Despite the supply expansion, months of supply fell to 2.4 from 2.6 a year ago—an indicator that demand growth outpaced supply growth. The median home took 50 days to sell, essentially unchanged from last year. Buyers found more options, but they had to move at a similar pace to secure a home.
New Listings Surged 11% but Demand Kept Pace
New listings in Lake County jumped 10.6% year over year to 920, nearly double the national 4% increase. Active inventory expanded 6% to 3,039. Yet even with that influx, months of supply declined to 2.4—well below balanced territory and far below the national figure of about 4. Demand grew fast enough to absorb the additional homes.
For sellers, the data confirmed that listing now was still a strong bet, since homes sold at essentially full asking price in a median of 50 days. For buyers, the 6% inventory increase provided marginally more options, but the falling months of supply meant the market was not loosening. Patience and preparation remained essential.

How Buyers and Sellers Can Navigate Lake County’s Market
If you’re buying in Lake County, the market offers more options than a year ago—inventory is up 6% and new listings surged 11%. But months of supply still fell, so don’t mistake more listings for a buyer’s market. Get pre-approved, target your price range carefully, and be ready to act decisively. In the starter and high tiers, about half of homes still sold above asking.
If you’re selling, the data supports listing with confidence. Homes sold at essentially full asking price, and the market absorbed a 10.6% increase in new listings without inventory building meaningfully.
