AI Lease Abstraction Accuracy: Benchmarks and What to Expect
What accuracy can you realistically expect from AI lease abstraction tools? We break down field-level accuracy rates, where AI excels, where it struggles, and how to validate output.
A side-by-side lease comparison template for evaluating multiple lease proposals or comparing an existing lease against a proposed renewal or alternative space. This template structures the comparison across economic, operational, and legal dimensions to support objective space selection decisions. It is particularly useful when comparing NNN, gross, and modified gross lease structures.

Used by corporate real estate teams, tenant brokers, and occupancy planners when evaluating two or more lease options, or when comparing a renewal proposal against a new space alternative.
Lextract automatically extracts these fields from your lease PDF — eliminating the manual data collection underlying this checklist.
Convert both to total occupancy cost per RSF. For a gross lease, the quoted rent already includes most operating expenses. For an NNN lease, add the base rent plus estimated taxes, insurance, and CAM. Then compare the total cost for each option, adjusting for any expense stop provisions in modified gross leases.
Calculate the effective rent net of TI allowance by amortizing the TI over the base term at an appropriate discount rate (typically 7-10%). A lease with $50/SF TI allowance has a meaningfully lower effective rent than one with no TI, especially for a first-generation space build-out. Include TI in net present value calculations for the most accurate comparison.
This depends on your capital position and business outlook. Companies with high growth uncertainty often prefer flexibility (more options, lower termination penalties) over maximum TI. Capital-constrained companies may prioritize maximum TI even at the cost of flexibility. Model both scenarios with realistic probability weights.
