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.
Streamline annual portfolio reviews with Lextract. Batch-abstract entire lease portfolios, identify underperformers, track expirations, and export structured data for analytics.

Annual portfolio reviews require extracting current lease data across dozens or hundreds of properties to identify underperforming leases, upcoming expirations, and renegotiation opportunities. Most organizations rely on stale data in their property management systems because re-abstracting the portfolio manually is prohibitively time-consuming. This means investment decisions are made on incomplete or outdated information, and optimization opportunities are missed until they become urgent problems.
Lextract enables teams to re-abstract an entire portfolio in a single day. Upload the current lease documents, receive structured data for every tenant, and immediately identify leases with below-market rents, upcoming rollovers, or unfavorable terms. The batch export provides a clean dataset for portfolio analytics, comparison against market benchmarks, and prioritization of renegotiation targets.

Best practice is to re-abstract annually or whenever a significant amendment is executed. At $20 per lease, annual re-abstraction of a 50-lease portfolio costs just $1,000 — far less than the cost of making decisions on stale data.
Yes. You can export structured data from each abstraction session and compare them in Excel or your analytics platform to track changes in rent, operating expenses, and lease terms over time.
