Frequently Asked Questions

How many fields does Lextract extract from a lease?
Lextract extracts 126 structured fields from every commercial lease PDF. These fields span 14 categories including parties and property, key dates and term, rent and escalations, CAM and operating expenses, options, tenant improvements, insurance, assignment, default, exclusivity, parking, utilities, signage, and miscellaneous provisions.
What types of fields are extracted from a commercial lease?
Extracted fields cover the full spectrum of commercial lease data: financial terms (base rent, CAM caps, operating expense stops), critical dates (commencement, expiration, option deadlines), tenant rights (renewal options, ROFO, termination rights), and legal provisions (assignment restrictions, SNDA requirements, holdover rent). Each field includes a confidence score — High, Medium, or Low — based on AI extraction quality.
Are all 126 fields extracted from every lease?
Lextract attempts all 126 fields on every lease, but not every field is present in every document. For example, a gross lease will not have separate NNN expense fields, and a lease without options will not populate renewal option dates. Fields absent from the source document are returned as null with an explanation, so you always know what was found versus what was not present.
What confidence scoring system does Lextract use for extracted fields?
Every extracted field receives one of three confidence levels: High (the AI found clear, unambiguous language and the source scan was clean), Medium (the provision was identified but contained ambiguous language or the scan quality was moderate), or Low (the field was flagged for human review due to poor source quality or conflicting language). Low-confidence fields are automatically highlighted in the results dashboard.
Which fields are most commonly used in lease abstracts?
The most referenced fields in commercial lease abstracts are base rent, lease commencement and expiration dates, tenant and landlord entity names, square footage, renewal options, CAM expense caps, rent escalation schedule, security deposit amount, and permitted use. Lextract extracts all of these as required fields — meaning they are always attempted and always included in exports.
