Lease abstraction typically costs between $25 and $150 per lease when outsourced to a service, while AI lease abstraction software runs on a monthly subscription that brings the effective cost well under $10 per lease at volume. The price depends on how complex the lease is, how many amendments it has, how fast you need it, and whether a human reviews the output. The biggest hidden cost, though, is doing it in-house by hand, where three to eight hours of analyst time per lease quietly dwarfs every other option.
What drives the price
Whatever route you take, a few factors move the cost of abstracting a single lease:
- Lease complexity. A clean office lease abstracts faster than a retail lease loaded with percentage rent, co-tenancy, and exclusives.
- Amendments and exhibits. Each amendment, side letter, and exhibit adds reading and reconciliation time.
- Field depth. A 15-field summary costs less than a 150-field abstract feeding a lease-administration system.
- Turnaround. Standard turnaround on outsourced work is two to five business days; rush work costs more.
- Quality assurance. A second-pass human review raises accuracy and price.
The main pricing models
Offshore and outsourced abstraction services
Dedicated abstraction firms, many staffed offshore, price per lease. Simple leases land around $25 to $50, standard commercial leases around $50 to $100, and complex retail or heavily amended leases $100 to $150 or more. Turnaround is usually two to five business days. This model works well for a one-time backlog, but the per-lease price never drops, so a recurring or large-portfolio program gets expensive, and you are dependent on someone else's queue and quality control.
AI lease abstraction software
Software replaces per-lease labor with a subscription. You upload the lease, the AI extracts the fields and links each one to its source page and clause, and a reviewer confirms in minutes. Plans are typically tiered by volume, so a team running dozens or hundreds of leases pays a few dollars per lease or less in effective terms, with the marginal cost of one more lease approaching zero. Because every field is source-linked, the review step is fast, which is what makes the low effective cost real rather than theoretical. See our pricing for current plans.
Doing it by hand in-house
This looks free because there is no invoice, but it is usually the most expensive option. At three to eight hours per lease and a loaded analyst rate, a single lease can cost well over $150 in time alone, and it pulls skilled people off higher-value work. It also scales the wrong way: the only way to abstract more leases is to add more hours or more headcount.
Cost comparison at a glance
| Approach | Typical cost | Turnaround | Best for |
|---|---|---|---|
| In-house by hand | $150+ in time/lease | Hours per lease | One-off, low volume |
| Outsourced service | $25 to $150/lease | 2 to 5 days | One-time backlog |
| AI software | Subscription, under $10/lease at volume | Minutes per lease | Recurring and at scale |
The hidden costs to count
The sticker price is only part of the math. Two costs rarely show up on an invoice but matter more than the rest:
- Error cost. A missed renewal deadline or a mis-stated escalation can cost far more than the abstract itself. Source-linked output that a reviewer can verify quickly is the cheapest insurance against this. See critical dates and escalations.
- Re-abstraction cost. Leases get amended. If your process makes it painful to re-run an abstract when an amendment lands, you pay again every time. Software that re-abstracts on upload removes that recurring charge.
How to choose
Match the model to the work. For a single lease or a tiny one-time backlog, paying a service per lease is fine. For a recurring program, a growing portfolio, or any team that values fast verification, AI software is almost always the lowest total cost once you count time and error. If your team currently abstracts in-house, the time you are already spending is usually enough to justify the switch on its own.
