FAQ
How should a CRE team use this article?
Use it as a checklist for the questions to ask during underwriting, not as a substitute for source-backed deal review. The final model still needs document citations, market checks, review states, and clear assumption ownership.
Where does Cactus fit in this workflow?
Cactus reads deal-room materials, checks assumptions against market context, surfaces conflicts, lets users approve the facts that drive the model, and preserves the logic as Proprietary Memory for the next deal.
Excel-based financial modeling is costing you deals. While you're manually updating spreadsheets, your competitors are leveraging AI to close more deals, faster. Here's exactly how the industry is transforming, and why many can't afford to fall behind.
Let's be direct: Excel-based financial modeling is costing you deals. While you're manually updating spreadsheets, your competitors are leveraging AI to close more deals, faster. Here's exactly how the industry is transforming, and why many can't afford to fall behind.
The Real Cost of Excel Dependency

- Version control becomes impossible across teams
- Complex portfolios overwhelm basic spreadsheet capabilities
2. Speed and Accuracy Trade-offs
Forced to choose between:
- Rushed analysis with high error risk
- Thorough analysis that takes too long
- Simplified models that miss crucial nuance

How Cactus turns this into defensible underwriting
The workflow matters because the model is only one artifact. Cactus connects the deal package, market evidence, reviewer decisions, Excel outputs, templates, and Proprietary Memory so the work survives handoffs instead of disappearing into a one-off spreadsheet or chat thread.
- Extract relevant facts from OMs, rent rolls, T-12s, leases, PDFs, spreadsheets, and customer templates.
- Check rents, expenses, growth targets, cap rates, sales comps, and site context against market intelligence from premium data providers, public records, and firm history.
- Surface conflicts, confidence states, reviewer comments, and assumption overrides before the model becomes the memo.
- Populate Excel or Cactus models, then store approved facts, templates, comps, and decisions in Proprietary Memory for the next deal.
The point is not to make the model less sophisticated. The point is to make the source, market check, assumption owner, review state, and output path visible before the number reaches a partner, lender, client, or investment committee.
Defensible underwriting
Defend every number before it reaches IC.
Cactus gives CRE teams ARGUS-grade underwriting intelligence with document extraction, market checks, source trails, reviewable assumptions, Excel-ready outputs, and Proprietary Memory around the workflow.
- Rent rolls, T-12s, OMs, comps, and assumptions live in separate files.
- Market evidence gets copied into the model without a durable source trail.
- Reviewer decisions disappear after the memo, email thread, or spreadsheet version changes.
- Extract deal facts from OMs, rent rolls, T-12s, leases, PDFs, spreadsheets, and customer templates.
- Check rents, expenses, growth targets, sales comps, and other assumptions against market intelligence.
- Populate Excel or Cactus models and preserve approved logic as Proprietary Memory.
