Built for
For commercial real estate acquisition teams that receive more opportunities than analysts can fully review and need repeatable first-pass underwriting without a generic black-box model.
AI underwriting software for commercial real estate
Apply your firm’s underwriting judgment to every commercial real estate deal
Rook handles the document reading, reconciliation, and model population that slow acquisition teams down—while your firm keeps control of the assumptions and decision.
The outcome
Give every viable opportunity a source-connected first pass in the firm’s own model, then direct senior attention to the assumptions, conflicts, and risks that actually require judgment.
How it works
From source package to reviewable work
- 01
Collect the complete deal record
Bring the OM, rent roll, T12, spreadsheets, model, and supporting diligence into one opportunity record.
- 02
Extract and reconcile the evidence
Rook structures facts from each source, retains provenance, and surfaces material disagreement instead of quietly selecting a convenient number.
- 03
Populate the firm’s model
Reviewed facts and clearly labeled assumptions map into the Excel workbook, units, signs, and periods the team already uses.
- 04
Move from model to decision
Screen the opportunity, investigate exceptions, run scenarios, and prepare committee materials from the same connected evidence.
What the team gets
Fast enough to use. Clear enough to review.
Firm-specific model support
Preserve the formulas, structure, and decision logic embedded in the workbook your team has refined over time.
Source traceability
Keep material inputs connected to the document and context from which they were extracted.
Fact and assumption separation
Historical observations, forward assumptions, and unresolved questions remain visibly different throughout review.
Acquisition workflow continuity
Carry the underwrite into screening, diligence, pipeline review, and investment committee preparation without re-keying the deal.
Why the details matter
AI should expand judgment coverage, not manufacture certainty
Commercial real estate underwriting is not a single calculation. It is a chain of evidence, normalization, market context, financing, assumptions, and firm-specific decision rules. Useful AI accelerates that chain without pretending uncertainty disappeared.
Rook is designed around reviewable work. A number can retain its source, period, unit, and sign; a proposed forward input can carry its reasoning; and a conflict can remain open until the team resolves it.
The benefit is coverage. More opportunities can reach a meaningful first pass, while analysts and principals spend their time testing the investment case rather than rebuilding source documents by hand.
Frequently asked questions
Questions acquisition teams ask
What is AI underwriting software for commercial real estate?
It is software that uses AI to read property documents, structure financial and operating data, populate analysis, and help teams review deals. A serious workflow keeps assumptions and source evidence visible rather than producing an unexplained valuation.
Does Rook replace our Excel underwriting model?
No. Rook is designed to populate and work with the Excel model your firm already trusts, preserving the model’s formulas, conventions, and decision process.
Which documents can the software use?
A typical package includes an offering memorandum, rent roll, T12 or other operating statement, workbook, and supporting diligence. The available analysis depends on the files supplied for the deal.
How does the team verify AI-generated underwriting?
Reviewers can inspect source references, distinguish extracted history from assumptions, investigate exceptions, and compare the populated model with the original deal package before relying on the result.
