Abstracting a commercial lease is a systematic field-by-field extraction followed by a verification pass. Done properly it covers 80 to 100+ fields and takes a trained abstractor 3 to 5 hours per lease. Here is the complete process and the order experienced abstractors work in.
Parties, Premises, and Financial Terms
Start with the parties and premises: landlord, tenant, guarantor, property address, suite, rentable and usable square footage, common area factor. Then the financial core — the base rent schedule for every year of the term, not just Year 1. A 10-year lease with annual 3% escalations has 10 different annual rent amounts, and each one belongs in the abstract. Capture security deposit, free rent or abatement periods, and the tenant improvement allowance.
Operating Expenses and CAM
Identify the lease structure: NNN, gross, modified gross, or base year. For NNN leases, identify which operating expenses pass through. Capture the CAM definition, the controllable expense cap (typically 3% to 5% per year), and critically, whether that cap applies to controllable expenses only or total CAM, and whether it cumulates year over year or resets annually. These details determine real dollar exposure.
Critical Dates and Quality Check
Capture commencement, rent commencement, expiration, renewal option deadlines, and termination notice windows. Then run the quality check: verify the escalation math (Year 1 of $50,000 with 3% increases means Year 5 is approximately $56,275), verify date consistency (a January 1, 2023 commencement on a 10-year term expires December 31, 2032), cross-reference every amended term against amendments, and flag any field not found rather than leaving it blank.
