Lake County, IL Rent Prices by Neighborhood

The Rent Story: Rising, and Structurally Supported

Lake County rents are moving higher, and the data backs that direction. The county's median rent sits at $2,251 per month as of mid-2026, and the conditions that push rents up are firmly in place: supply at 2.1 months countywide, rate lock-in that keeps would-be sellers off the market, and a Fortune 500 employer base that consistently draws white-collar renters to the area.

The employer engine is the clearest driver. AbbVie, Abbott, Walgreens, Medline, and Wintrust Financial collectively make Lake County the second-largest concentration of Fortune 500 headquarters in the Midwest. In 2025, AbbVie, Flex, and Fortune Brands Innovations were all expanding or modernizing operations here. County unemployment stood at 4.6% in August 2025, close to full employment. When large, diversified employers are growing and workers need housing, landlords hold pricing power.

New construction starts are up 8% in the Libertyville, Mundelein, and Vernon Hills corridors in 2026, which adds some supply. However, the pipeline is unlikely to offset the structural shortage created by rate lock-in. Owners who refinanced at 3–4% in 2020–2022 are not selling, and that keeps resale inventory suppressed across all price tiers.

The forecast out of DePaul University's Institute for Housing Studies and Illinois REALTORS projects about 5% price growth and roughly 5.1% higher sales activity for the Chicago metro in 2026. That macro tailwind extends to Lake County's rental market: when ownership becomes marginally less affordable, renting becomes relatively more attractive, which keeps occupancy rates elevated and supports rent growth.

Sub-Market Rent Breakdown

The Research Brief does not provide sub-market-level ZORI data by neighborhood, but entry price points and appreciation rates by community offer a practical guide to where rent tiers fall.

High-end: Lake Forest and Highland Park. These communities attract Chicago-area executives, physicians, and finance professionals. Rents in this tier sit well above the $2,251 county median, reflecting luxury product and commuter convenience.

Middle market: Grayslake, Libertyville, Gurnee, and Lake Zurich. These are the tightest supply environments in the county heading into late 2025. Inventory in these communities is especially constrained. Rents here cluster close to or modestly above the county median, making them the stable core of Lake County's rental market.

Entry tier: Waukegan. The county seat posted a median home sold price of $235,000 in March 2025, roughly 41% below the county median. Rents track lower accordingly. Waukegan carries the highest inventory and the county's highest foreclosure concentration (101 foreclosure properties as of the latest data), which means downward rent pressure from distressed units is a real factor. This sub-market suits experienced investors targeting deep-discount acquisitions, not renters seeking a polished product.

Relative-value lakefront: Winthrop Harbor. With a December 2024 median sold price of $294,995 and 11.4% year-over-year appreciation, this small northern community is priced below the county median but appreciating faster than most. Rents are likely below the county median in absolute terms but are moving up with the price appreciation signal.

Affordability: What Rent Costs You Here

At $2,251 per month, Lake County's median rent runs $27,012 annually. The brief does not supply a current Lake County median household income figure, so a direct income-share calculation cannot be made here. Run your numbers through our Rent vs Buy calculator if you're weighing renting vs buying and want to model what share of your specific income goes toward housing.

What the brief does confirm: Lake County's 2.43% effective property tax rate (the highest of any county in Illinois) is a major factor in why rents are as high as they are. Landlords face a median annual property tax bill of about $8,943. At a median home price of $400,964, that tax line alone represents roughly $745 per month in operating cost before a mortgage, insurance, or maintenance dollar is spent. Some of that cost is passed through to tenants in the form of higher asking rents.

The 30% rule benchmark: at $2,251 per month, a renter would need gross annual income of about $90,000 to stay within that threshold. In high-demand communities like Libertyville and Lake Forest, rents above the county median push that income requirement higher. Waukegan remains the clearest path to below-median rents in the county, though renters should factor in neighborhood conditions and management quality.

12-24 Month Rent Forecast

Several forces will shape Lake County rents through mid-2027.

Supply additions. New construction starts are up 8% in the Libertyville-Mundelein-Vernon Hills corridor. New residential projects like Fox Lake Crossing are under construction. These additions will increase available units in specific sub-markets. Renters in those corridors may see modest concession offers from new properties competing for tenants. Landlords in those zones should expect to work harder on retention in 2026-2027.

Employer activity. Active expansions from AbbVie, Flex, and Fortune Brands Innovations signal continued hiring demand. Healthcare and higher education anchors (Rosalind Franklin University, College of Lake County, Lake Forest College) feed major health systems in the county, adding a recession-resistant renter pool. These employment drivers support occupancy across product types.

Code changes. The Lake County Board adopted the 2024 ICC code series in May 2025, effective July 12, 2025 for unincorporated areas. Higher renovation and construction costs from updated codes can slow new supply and raise rehab costs, which indirectly supports asking rents on existing inventory.

Metro-level tailwinds. The projected 5% price growth for the broader Chicago metro reduces the financial case for buying, routing more households into the rental market and supporting occupancy.

Overall: expect modest rent growth in the 3–5% range over the next 12–24 months, with tighter conditions in middle-market communities and softer conditions in corridors receiving new construction.

If You're a Renter

1. Target Metra proximity carefully. Lake County's 32 Metra stations draw a broader renter pool, and landlords price that in. If you do not commute to Chicago by train, a location farther from Metra reduces your rent without sacrificing access to the county's employer base.

2. Compare Waukegan carefully. Entry-level rents in Waukegan are the lowest in the county, but the highest foreclosure concentration means rental stock quality is uneven. Visit properties in person, verify ownership history, and confirm the landlord is current on taxes before signing a lease.

3. Watch new construction in the Libertyville-Mundelein-Vernon Hills corridor. New buildings in this zone may offer concessions (free months, reduced deposits) to fill units quickly. A 12-month lease signed in a lease-up property often comes with better terms than the same building offers at stabilization.

If You're a Landlord

1. Underwrite property taxes at current assessed value, not purchase price. At a 2.43% effective rate, reassessment risk is real. The county's taxing districts range from 2.0% to 3.5%, so the district you buy in directly affects your net operating income. Verify the specific district rate before closing, and model a scenario where the effective rate moves toward the high end of that range.

2. Hold position in Grayslake, Libertyville, Gurnee, and Lake Zurich. These communities have the tightest supply and the most stable renter profiles. Vacancy risk is low, and turnover costs are your primary enemy. Invest in tenant retention: responsive maintenance and small rent increases well below market (2–3%) on renewals cost less than a vacancy.

3. Approach Waukegan value-add with realistic underwriting. A $235,000 entry price is the most attractive in the county, but 101 foreclosure properties in one city means management intensity is elevated. Budget for higher tenant turnover, factor in the 2.43% tax rate on the assessed value post-renovation, and confirm your exit strategy before acquiring. This sub-market rewards experienced operators, not passive owners.
