Lease abstraction is the process of reading a lease and extracting its key terms into a short, structured summary, the abstract. It lets a buyer, lender or asset manager compare and track many leases without rereading each one.
What is abstracted
- Parties and premises. Landlord, tenant, guarantor, suite and square footage.
- Term. Commencement, expiration, renewal and termination options and their notice periods.
- Rent. Base rent, escalations, free rent, and how rent is reset at renewal.
- Expenses and recoveries. Who pays taxes, insurance and operating costs, and how they are shared.
- Deposits and guarantees.
- Rights and restrictions. Assignment and subletting, exclusives, co-tenancy, purchase options, rights of first refusal.
- Critical dates. The deadlines that carry a cost if missed.
Why it matters in diligence
The rent roll lists what the seller says the tenants pay. The leases say what they are actually obliged to pay, for how long, and with what rights. A buyer who checks the abstract against the rent roll finds the gaps: a rent that is not what the lease says, an option nobody mentioned, a termination right that lowers the value of the income.
How to check an abstract
Every abstracted term should point to the page and clause it came from, so a reviewer can open the lease and confirm it in seconds. Abstracts that cannot show their source should be treated as drafts. Differences between the abstract and the rent roll are the findings that matter most.
