Lease Audit: Faster with AI Lease Abstraction

Make systematic lease audits practical with Lextract. Extract structured data from lease documents, compare against system records, and identify billing discrepancies in hours instead of months.

The Problem

Systematic lease audits are essential for maintaining portfolio accuracy, ensuring billing compliance, and catching costly errors — but they are rarely performed because of the time required. Auditing a single lease against property management system data requires re-reading the entire document to verify that every field in the system matches the actual lease language. Across a portfolio, this process can take months, during which billing errors, missed escalations, and incorrect expense pass-throughs continue unchecked.

How Lextract Helps

Lextract makes lease audits practical by extracting structured data from the actual lease documents in minutes. The extracted fields can be directly compared against what is currently stored in the property management system to identify discrepancies. This turns a months-long manual audit into a days-long data comparison exercise. Red flag detection adds another layer by identifying provisions that may be misconfigured in billing systems, such as missing caps, incorrect reconciliation schedules, or absent exclusion lists.

Frequently Asked Questions

How is a lease audit different from lease abstraction?

Lease abstraction extracts data from the lease document. A lease audit compares that extracted data against what is currently stored in your property management system to identify discrepancies. Lextract handles the extraction step, making the comparison step fast and straightforward.

How often should I audit my lease portfolio?

Industry best practice is to audit every lease at least once every 2-3 years, and immediately after any system migration or major amendment. At $20 per lease, Lextract makes annual audits economically feasible for portfolios of any size.

What are the most common discrepancies found during lease audits?

The most common errors are incorrect escalation rates, wrong base years for expense pass-throughs, missing or incorrectly applied CAM caps, outdated pro rata shares after building modifications, and missed amendments that changed key economic terms.
