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.
