Portfolio managers and REIT investors need portfolio-wide visibility into lease economics, but lease data is typically trapped in PDFs across dozens of properties and hundreds of tenants. Building accurate portfolio models requires base rent, escalation schedules, lease expirations, and operating expense structures for every lease — data that is prohibitively expensive and slow to extract manually. Without structured lease data, portfolio-level decisions about dispositions, refinancing, and capital allocation rely on incomplete or outdated information.
Lextract enables portfolio managers to rapidly digitize entire lease portfolios and extract the structured data needed for portfolio analytics and reporting. Batch processing handles hundreds of leases efficiently, producing standardized data across all properties. The structured export integrates directly with portfolio management tools and financial models. Automated red flag detection provides a risk heat map across the portfolio, highlighting properties with concentrated lease-level risks that could affect NOI stability.
