Commercial Cap Rates in Lake County, Illinois
Current capitalization-rate ranges for multifamily, retail, industrial, and office property across Lake County and the north suburbs — and what moves a specific building inside each band.
As of Q2 2026, stabilized commercial property in Lake County typically trades in the ranges above. These are ranges for occupied, stabilized assets — tenant credit, lease term, building age, and submarket move any one property within or beyond them.
Cap rates by asset class
Lake County and the north suburbs run a touch wider than the Chicago metro core — a secondary-market premium for thinner buyer pools and longer marketing times. Here’s where stabilized product trades right now, and what moves a property inside each band.
| Asset class | Typical range | What moves it |
|---|---|---|
| Multifamily | 6–6.5% | Class A trades tighter; Class C and value-add wider. Unit count, condition, and tax reassessment exposure at sale are the swing factors. |
| Retail | 7–8% | Single-tenant net lease to a credit tenant trades to the low end (≈6.5–7%); multi-tenant strip, weak co-tenancy, or short lease term pushes it higher. |
| Industrial | 7–8% | Modern logistics and O’Hare-corridor product trades to the low end; older, smaller, or functionally obsolete flex with leasing risk trades to the high end. Tracks the ~7.5% CBRE metro benchmark. |
| Office | 9.5%+ | Suburban multi-tenant office has repriced sharply. Medical office and credit net-lease trade tighter; vacancy and near-term rollover widen it considerably. |
Retail and industrial currently occupy the same band. That’s the 2026 story — industrial cap rates drifted up into retail territory as a wave of new supply leased up, narrowing a gap that used to be wide. It signals the two sectors are pricing similar risk right now, not an error.
Why the cap rate you’re quoted isn’t the cap rate you get
A cap rate is just net operating income divided by price — simple math on top of numbers that are easy to inflate. The headline figure in a marketing package is often built on a seller’s pro forma, not reality. Four things erode it between offer and closing:
Tax reassessment
A sale price gives the county assessor a fresh data point, and reassessment can push the tax bill up — sometimes sharply. One of the biggest cap-rate eaters between offer and closing.
Real vs. pro-forma rent
Marketed NOI often assumes rents above what current leases deliver. The real cap rate uses in-place income, not “market potential.”
Operating costs
Insurance especially has climbed hard across Illinois. Old pro formas underbudget it, and that comes straight out of NOI.
Capex reserves
Roof, parking, HVAC, tuckpointing — a building with no reserve in the pro forma is hiding cost. A true reserve lowers the real return.
Run those four honestly and a “9 cap” can become a 7. That gap is where buyers overpay and sellers leave money on the table — and it’s why a cap rate alone never tells you what a property is worth.

Common questions
What is the average commercial cap rate in Lake County, IL?
As of Q2 2026, stabilized commercial property in Lake County and the north Chicago suburbs trades in these typical ranges: multifamily 6 to 6.5 percent, retail 7 to 8 percent, industrial 7 to 8 percent, and office 9.5 percent and up. These are ranges for occupied, stabilized assets in normal market conditions; quality, location, tenant credit, and lease term move any individual property within or outside them.
What is a good cap rate for a retail strip center in Lake County?
Multi-tenant retail strip centers in Lake County generally trade in the 7 to 8 percent range as of Q2 2026. A single-tenant property on a long-term net lease to a credit tenant trades tighter, often closer to 6.5 to 7 percent, because the income is more durable. Weak co-tenancy, short remaining lease term, or a soft anchor pushes the cap rate higher.
What cap rate do industrial buildings trade at near the O'Hare corridor?
Industrial in the north Chicago market trades around 7 to 8 percent as of Q2 2026, tracking the CBRE metro benchmark of roughly 7.5 percent. Modern logistics and well-located product near the O'Hare corridor and the interstates trades to the low end of that band, while older, smaller, or functionally obsolete flex space with leasing risk trades toward the high end.
Why is the cap rate I was quoted different from the one at closing?
Because a quoted cap rate is often built on the seller's pro forma, not real numbers. Four things erode it between offer and closing: property tax reassessment, where a sale can prompt the assessor to raise the assessed value; real in-place rents that fall short of the marketed rents; operating costs — especially insurance — that have risen sharply; and capital-expenditure reserves the pro forma left out. A real cap rate uses actual leases, reassessed taxes, honest vacancy, and a true capital-expenditure reserve.
