Manually entering 20–50 leases during due diligence creates bottlenecks, and keying errors are difficult to catch before they flow through to the cap rate analysis.
Upload the full set of executed lease PDFs. Batch processing allows multiple documents at once, accelerating due diligence timelines.
Lextract extracts tenant name, lease start and expiration, base rent by period, escalation type and rate, free rent periods, options, and CAM structure — all inputs for an ARGUS model.
ARGUS models are sensitive to escalation rates and option exercise dates. Review any flagged fields against the source lease before building the model.
Download the extracted lease data as an Excel file structured for ARGUS import or manual entry into the ARGUS lease tab.
Enter or import the extracted lease data into ARGUS Enterprise. Validate the rent roll output against the Lextract abstracts before running the full DCF.

View ARGUS Enterprise integration →Lextract exports use standard CRE terminology that maps directly to ARGUS lease inputs: base rent, rent steps, CPI escalation, free rent, and lease expiration date. The Excel export is structured to minimize re-labeling.
Lextract identifies CPI escalation provisions and extracts the base year, cap on increase, floor, and applicable CPI index. You then enter the appropriate CPI assumptions in ARGUS.
