The Lake County housing market in May 2026
Prices in Lake County are still climbing: the median sale price reached $434,429 in May 2026, 6.0% above a year earlier. Homes listed that month had a median asking price of $449,888, and sold for a median of $233 per square foot. The average sale closed at 101.5% of asking price and 50% of homes sold above list, so buyers are still bidding against each other.
There were 2,055 homes for sale at the end of May, down 2% from a year earlier, or 2.6 months of supply, still on the sellers' side. The typical home that sold had been listed for 45 days, 3 days less than a year earlier. 63% of homes went under contract within two weeks of listing. Compared with May 2025, owners listed 1% fewer homes and sales were down 5%.
Only 14% of listings had a price cut in May 2026 (1.7 points fewer than a year earlier), so most sellers are getting close to their asking price.
For FSBO outreach, this means many Lake County owners can still sell on their own, so lead with pricing data and a net-proceeds comparison rather than an offer to list.

With prices near the top of the Illinois counties profiled here, each percentage point of commission is worth more to Lake County owners, so a net-proceeds comparison carries extra weight.
Lake County since 2019
The median sale price averaged about $422,000 from March to May 2026, up 74% from about $243,000 in the same months of 2019.
Prices are at or near their highest level since at least 2019.
Supply is still below pre-pandemic levels: about 1,860 homes were for sale in an average month in spring 2026, against 4,750 in spring 2019, 61% fewer.
In spring 2026 the median time on market averaged about 47 days, 25 days less than in spring 2019 (73 days).
Owners are listing about 39% fewer homes a month than they did in spring 2019.
For FSBO outreach, supply that is still tight by 2019 standards means a well-priced Lake County FSBO can sell fast, so reach owners early.
When Lake County homeowners list
Listing activity is strongly seasonal in Lake County. Over the three years to May 2026, new listings peaked in April and May, with May running about 41% above the monthly average, and bottomed out in December, about 55% below it. Homes that sold in June had spent the least time on the market (a median of about 46 days), and those that sold in January the most (about 67 days).
Have your list, scripts and mail pieces ready by March, so you reach new FSBO owners in their first weeks. Sales are slowest around January, so FSBO owners still on the market then have often been waiting for months and tend to be the most open to help.

Working Lake County FSBO leads
- Split the list by city. Highland Park (median $914,000) and Waukegan (median $260,000) sit 252% apart on price, and Highland Park also had the most sales in May 2026 (48), so one script will not fit every owner.
- Time it. Put your heaviest outreach into April and May, when the most Lake County homes come to market, and ease off in December.
- Bring the numbers. On a $434,429 home, each 1% of commission is about $4,344, the money most FSBO owners are trying to keep, so a net-sheet comparison lands better than a pitch.
- Use the 45-day mark. Half of the Lake County homes that sold in May 2026 had been listed 45 days or less, so an FSBO still for sale after that is likely stalling.
- Stay compliant and verify. Stop contacting any owner who says "no agents" or "no investors", confirm ownership and liens in Lake County records before an offer, and add skip tracing for records without a phone number.

- Calls and texts. Screen numbers against the National Do Not Call Registry and get written consent before automated texts.
- Records. Deeds are recorded with the county recorder (in Cook County, the County Clerk's recordings division), and assessments are set by the county or township assessor. The county seat is Waukegan.
