A focused lease abstraction process conducted during property acquisition or financing, where all active leases are reviewed and abstracted to identify material risks, obligations, and economic terms that affect the deal valuation.
In acquisition due diligence, buyers and lenders abstract target property leases to verify rent roll accuracy, identify unusual tenant rights (termination options, co-tenancy clauses, recapture rights), confirm lease expiration schedules, and surface hidden liabilities (unfunded TI obligations, deferred maintenance responsibilities). The timeline for due diligence abstraction is typically compressed — 2–4 weeks for a portfolio of 50–200 leases. AI abstraction tools compress this timeline further. Key outputs include a lease summary matrix, a critical date schedule, and a risk issue log. Deal-breaking provisions (e.g., co-tenancy rights that could collapse projected NOI) must be surfaced before closing.
