  • Spot rent roll mismatches before the deal closes
  • Find 20 types of lease risks with one upload
  • Export data to Excel for Argus or your deal model

The Challenge

Buying a property means checking every lease first. That work is called due diligence. A typical deal has 10 to 50 leases. You need the rent roll ready fast. The rent roll lists every tenant and what each one pays. Reading each lease by hand takes 4 to 8 hours. One missed clause can change what the property is worth. A bad renewal option or a recapture right can hurt the deal.

How Lextract Solves It

Upload your full lease stack. Lextract reads every PDF. It pulls 126 fields from each lease. Each lease takes about 5 to 15 minutes. All leases run at the same time. The AI flags 20 types of deal risks. Compare the results to the seller's rent roll. Then export the data into your deal model. Underwriting is the math behind the deal. Lextract feeds your numbers directly.
