Guide AI due diligence
AI due diligence in commercial real estate
How AI speeds up commercial real estate due diligence, what it checks, what still needs counsel, and the tools to look at.
Answer first: AI speeds up due diligence by reading every document in the data room and checking them against each other: leases against the rent roll, estoppels against leases, the T-12 against bank statements. It flags conflicts with a link to each page.
What AI checks
Index the data room and sort documents by type.
Extract key terms from leases, estoppels and contracts.
Compare documents against each other and flag conflicts.
Build the diligence checklist with each item linked to its source.
Draft the summary for the deal team and counsel.
What still needs a person
Judging which conflicts matter and what to do about them. Counsel and the deal lead decide; AI makes sure nothing is missed.
