Eleven free guides to industrial and commercial real estate in Chicago and the nine-county Chicagoland region—how buildings work, how deals are researched and underwritten, and where the official records live. Search every section or browse below.

Industrial property

Industrial due diligence

Environmental assessments, property condition, title and survey, zoning and permits, utilities, and how findings become price, credits, or repairs.

Submarkets & logistics corridors

O’Hare, I-55, I-80/Joliet, I-88, I-90, North Cook/Lake, South Cook, the city’s industrial corridors, and the outer counties—geography and freight infrastructure.

Nine Illinois counties

Cook, DeKalb, DuPage, Grundy, Kane, Kendall, Lake, McHenry, and Will—county-by-county authorities, assessors, and official sources.

Selling an industrial property

Buyer types for 10,000–100,000 SF, how they underwrite, value drivers, the document checklist, pricing, and the sale process.

Transactions and research

Investment & purchase diligence

Income, expenses, financing, downside cases, and the legal, physical, environmental, and tax reviews before closing—with calculators.

Comparing commercial leases

Gross vs. net terms, total occupancy cost over the term, a lease-review checklist, and making the move-in schedule credible.

Industrial & investment glossary

Plain-English definitions of building, lease, underwriting, and Illinois records terms, each with its own link and a live filter.

Scope. These guides are educational—not listings, appraisals, or legal, tax, engineering, environmental, or investment advice. “Chicagoland” here means the nine Illinois counties I work in. Verify records and requirements with the responsible offices and qualified professionals.
