Building a lease roll from a set of PDF lease documents requires extracting tenant name, premises, rent, term, and options from each document and assembling them into a single spreadsheet. Without extraction tooling, this is a days-long manual project for any property with more than a handful of tenants.
Gather all executed lease PDFs for the property, including amendments and side letters.
Upload each lease PDF to Lextract for batch processing.
Lextract extracts tenant name, suite or unit, RSF, base rent, lease commencement, lease expiration, renewal options, and security deposit — the standard columns in a commercial rent roll.
Download all lease abstracts as a single Excel export with one row per tenant and standard rent roll column headers.
Review the assembled rent roll for completeness. Add calculated columns: remaining term, annualized rent, and expiration year bucket. Validate total RSF against the building RSF.
