Summary: How CRE sponsors should run a secure data room: what to include, permission tiers, watermarks, view logs, version control, Q&A handling and a launch checklist.

**In short:** A data room is a controlled online space where a sponsor shares offering and diligence documents with investors and advisers. Unlike emailing attachments or sharing open links, it lets you decide who sees which documents, record every view and download, update files in one place and revoke access when needed. For anything sensitive, it is the difference between sharing documents and controlling them.

## Key Takeaways

- **Control access by person and by folder,** not with a single open link.
- **Log views and downloads,** so you know who saw what and when.
- **Keep one current version** of each document, with history.
- Use **structured folders** that match how investors review a deal.
- Apply **protections** such as watermarks and download limits where appropriate.
- **Remove access** promptly when someone is no longer involved.

## What Goes in the Room

| Folder | Typical contents |
|---|---|
| Overview | Executive summary, business plan, deal terms |
| Property | Description, photos, surveys, environmental and condition reports |
| Financials | Underwriting, rent rolls, operating statements, projections |
| Market | Market analysis, comparables |
| Legal | Structure, key agreements, title and zoning information |
| Sponsor | Track record, team, references |
| Subscription | Forms and instructions for investors |
| Q&A | Questions and answers log |

Include only what you are permitted and prepared to share, and have counsel review sensitive items.

## Access Control Design

- **Tiers:** for example prospects see overview materials, committed investors see full diligence, advisers see legal and financial folders.
- **Individual accounts,** not shared logins.
- **Time limits** on access where appropriate.
- **Download and print controls** for the most sensitive files.
- **Watermarks** with the viewer's name and date, which deter leaks.
- **Two-factor authentication** for users.
- **Instant revocation** for any user.

## Audit Trail

Record, at a minimum:

- Who accessed which document and when.
- Downloads and prints.
- Uploads, edits and deletions, with who made them.
- Permission changes.
- Questions asked and answers given.

This is useful when investors ask "what was I shown?", and when you need evidence of what was disclosed and when.

## Version Control and Updates

- Name documents consistently.
- Replace files in place and keep prior versions in history.
- **Notify** relevant users when something material changes.
- Do not email separate versions that bypass the room.

## Handling Q&A

Route questions through a log: question, date, who asked, assigned responder, answer and approval. Share answers to common questions with all investors where appropriate, so everyone has the same information. Have compliance review answers that could be material.

## Security Basics

Choose a provider or build with encryption in transit and at rest, strong authentication, role-based permissions, regular security testing and clear data handling terms. Understand where data is stored and how long it is kept.

## Launch Checklist

1. Define folders and who may see each.
2. Prepare, review and approve documents.
3. Create individual accounts and assign tiers.
4. Enable watermarks, logging and download rules.
5. Test with a dummy user in each tier.
6. Announce access with instructions.
7. Review the view log weekly and follow up on activity.
8. Close or archive the room after the raise, with a retention decision.

## Where AI Helps

- **Indexing and summarising** large document sets for the team's use, within the access rules.
- **Finding** inconsistencies between documents.
- **Drafting** answers to investor questions for review.

Any AI feature must respect the same access controls as the documents, and you should check how your provider handles data used by AI.

## How We Approach It

## FAQ

**What is a virtual data room?**
It is a controlled online space for sharing sensitive documents with defined people, with permissions, activity logs and version control, used for deals, diligence and capital raises.

**Why not share documents by email or open links?**
Email and open links give you little control over who sees what, no reliable record of access, and make it hard to update files or withdraw access.

**What should a real estate data room contain?**
Overview and terms, property information, financials, market analysis, legal documents, sponsor track record, subscription materials and a Q&A log, as approved by counsel.

**How do watermarks help?**
A watermark with the viewer's name and date discourages leaks and helps trace the source if a document is shared without permission.

**Should AI features be used on data room documents?**
Only if they respect the same access controls and your provider's data handling meets your requirements. Check how documents are processed and stored.
