The total base rent payable for the first full lease year.
Annual base rent is the single largest cost component in most commercial leases. It serves as the foundation for calculating holdover penalties (often 150-200% of base rent), security deposit requirements (typically 1-3 months), and the overall NPV of the lease obligation. Extracting the wrong figure propagates errors through every financial analysis downstream.
Defined in the "Rent" or "Base Rent" section, usually within the first 10 pages. Often presented as a schedule showing annual rent, monthly rent, and per-RSF rates for each year of the term.
Lextract uses vision AI to read your lease PDF natively (scanned or digital), then multi-pass AI validation identifies and extracts the annual base rent. The AI searches for all pages of the document, then assigns a confidence score based on document quality and extraction certainty. Fields with lower confidence are flagged for human review.
Base rent is usually quoted as a dollar amount per rentable square foot per year (e.g., $30/RSF/yr). To calculate monthly payments, multiply the per-RSF rate by the total RSF and divide by 12. A $30/RSF rate on 5,000 RSF equals $150,000/year or $12,500/month.
In a NNN lease, base rent does not include operating expenses -- those are billed separately. In a gross or full-service lease, base rent may include a base amount of operating expenses, with increases above the base year passed through as additional rent.
Total occupancy cost includes base rent plus all additional charges: CAM/operating expenses, real estate taxes, insurance, utilities, parking fees, and any other pass-throughs. Base rent alone often represents only 60-75% of total occupancy cost.
