Missing a lease expiration or option notice deadline can mean losing renewal rights or being locked into unfavorable holdover terms. Tracking these dates requires accurate data from every lease, and manual extraction means the tracker is only as good as the last person who read each document.
Upload the executed lease for every active tenant to Lextract.
Lextract extracts lease expiration date, renewal option notice deadlines, termination notice periods, rent escalation effective dates, and any lease-specific milestone dates.
Download the extraction as an Excel file with one row per lease and columns for each critical date type.
Load the extracted dates into an Excel tracker with conditional formatting to highlight upcoming expirations and notice deadlines within 90, 180, and 365 days.
Use the extracted dates to set reminders in Outlook or Google Calendar for each option notice deadline — at minimum 30 days before the deadline.
