Nearly every lease abstraction tool on the market was built for lease administration: a complete, maintained record of a portfolio you already own.
Acquisition diligence is a different job. You do not own the asset, you may not buy it, and you have weeks. The abstract exists to answer one question — does the income story in the offering memorandum survive contact with the documents — and then either to inform a price or to end the conversation.
Buying an administration tool for that job works, but it is worth knowing what you are adapting.
The Two Jobs, Plainly
| Administration | Acquisition diligence | |
|---|---|---|
| Asset | Owned | Under consideration |
| Horizon | Maintained for years | Weeks, then archived or handed over |
| Completeness | Every field, kept current | The fields that move price or risk |
| Failure | A record drifts stale | A clause is missed and the price is wrong |
The last row is the one that matters. In administration, an error is corrected at the next review. In diligence, an error is priced.
The Fields That Decide The Underwriting
A diligence abstract can be short if it is right about these:
- Remaining term and expiry, and how much of the rent roll rolls inside the hold.
- Rent and escalation mechanics — fixed, indexed, or to market, and what "market" is defined as.
- Free rent and outstanding concessions still owed to the tenant. These are frequently absent from the offering summary.
- Reimbursement structure, with its caps, floors, exclusions and base years. This is where stated NOI and real NOI diverge most often.
- Termination and contraction rights, and what triggers them.
- Renewal options, and specifically how the option rent is set. An option at a fixed below-market rent is a valuation event.
- Co-tenancy and exclusive-use clauses in retail, which can make one departure cascade.
- Assignment and change-of-control, which can be triggered by the transaction itself.
Everything else can wait for the administration abstract after closing.
Where Automated Abstraction Earns Its Place, And Where It Does Not
The extraction of standard, well-drafted fields is genuinely solved enough to rely on, with checking. Term dates, base rent, escalation percentages and square footage come out accurately from a clean document, and doing that across a hundred leases in an afternoon is real.
Two things deserve caution.
Bad scans. Diligence document sets are photocopies of amendments to photocopies. Test any tool on the worst document in your last deal, not on a clean sample.
Ambiguity. The clauses that matter are disproportionately the badly drafted ones — an escalation that could be read two ways, a reimbursement exclusion that may or may not cover a capital item. The correct behaviour is to surface the ambiguity. A tool that resolves it silently returns a clean abstract that has hidden the finding.
Cost, Honestly
Abstraction is priced per lease and the spread across providers is wide, because "per lease" covers very different work: a two-page retail lease and a heavily amended anchor lease are not the same unit. Offshore services, domestic services, in-house analyst time and software all sit at different points, and a per-lease price is only comparable if the field set and the review standard are the same.
The number worth calculating is not price per lease. It is the cost of the clause you did not find.
Where Titleman Sits
We read the lease stack against the underwriting rather than beside it: the extracted terms land in the model, the figures keep a reference back to the document and page they came from, and ambiguous clauses are flagged rather than resolved.
That makes the abstract an underwriting input instead of a parallel document someone reconciles by hand.
What It Does Not Replace
- Counsel's review of the leases, which is where a contested clause actually gets decided.
- A title search and the policy behind it.
- Estoppels and the tenant's own confirmation of what the documents say.
- The judgement of the person pricing the deal.
An abstract narrows what those people have to read. It does not stand in for any of them.
