AI Due Diligence Commercial Real Estate

Last week, I took a real DD folder, fed it into Claude Code in the terminal, and got results that would’ve taken days to compile manually, 15 minutes.

Here’s exactly what happened.

AI Due Diligence in CRE Setup Process

A member of the AI for CRE Collective (shoutout to Taylor from CRD) sent me a due diligence folder for a multifamily deal, rent roll, and P&L, ADU drawings, the whole set.

I opened Claude Code in the terminal. This is the most advanced way to use Claude. If you’re new to it, I’d recommend going through the Claude Masterclass first before jumping into terminal usage.

I used plan mode, which means Claude asked me clarifying questions before doing anything. What’s the asking price? How many units should I model? Should I run both scenarios? This is important because it forces the AI to understand your specific situation before executing.

Six AI Agents Running Simultaneously

After answering the clarifying questions, Claude launched six AI agents in parallel. Not one after another. All at the same time.

Agent 1: Pro Forma Builder

Took the rent roll and P&L data and built a full underwriting pro forma.

Agent 2: CAPEX Budget

Estimated construction costs for the ADU conversions. Came back with $250 per square foot for garage conversions, which is honestly a solid estimate.

Agent 3: Red Flag Report

Went through every document and flagged potential issues, inconsistencies, and areas that need deeper investigation.

Agent 4: DD Checklist

Generated a 65-item due diligence checklist, color-coded by status. Only three items came back as fully complete. That identification alone saves hours because you immediately know exactly what’s missing.

Agent 5: Seller Questions

Based on the gaps and red flags, it prepared a list of questions to send to the seller’s team.

Agent 6: Document Inventory

Cataloged everything in the folder, identified what’s there, what’s missing, and what needs to be added. Why AI Due Diligence in CRE Changes Everything

The traditional DD process involves one person (or maybe a small team) going through folders sequentially. Open the rent roll. Analyze it. Open the P&L. Cross-reference. Check the drawings. Build the checklist. Prepare questions.

Each step takes time, and you can only do one thing at once.

With Claude Code running six agents simultaneously, you’re running six analyses. Over time, the output from each agent is independent but complementary. Together, they give you a complete picture of the deal in a fraction of the time.

15 minutes for what would normally take a full day or more of focused work.

AI Due Diligence in CRE Checklist Review

I want to highlight this one specifically because it’s the kind of output that has immediate practical value.

65 items. Color-coded by completion status. The AI goes through every document and determines what was fully addressed,  partially addressed, and completely missing.

Only three items were fully completed. That’s not a reflection of a bad deal. That’s normal for early-stage DD. knowing immediately where the gaps are and discovering them over the course of weeks.

Print that checklist. Hand it to your analyst. They now have a clear roadmap instead of digging through folders, hoping they didn’t miss something.

AI Due Diligence in CRE Agent Workflow

How To Get Started With AI Due Diligence in CRE

You don’t need to jump straight into Claude Code in the terminal. Start with what you’re comfortable with.

Beginner

Use Claude’s web interface to analyze individual documents. Upload a rent roll and ask it to extract and summarize. Upload a P&L and ask it to flag anomalies.

Intermediate

Use Claude Projects to create a dedicated space for a deal. Upload all your DD docs and ask questions across the entire folder.
