A real estate data room is a controlled online space holding every document for a transaction, where you decide who sees which parts and can see who read what.
The term comes from M&A, where “the data room” was literally a room — a locked office holding the files, which bidders visited under supervision, signing in and out. The software version keeps the same idea: everything in one place, access controlled per person, a record of who looked at what.
How it differs from a shared folder
A Dropbox or Drive folder holds files. A data room holds files plus four things a folder doesn’t have:
- Structure. The order is deliberate. A buyer sees the offering memorandum first and the parking agreement last, because you decided that — not because of alphabetisation.
- Permissions per section. A lender sees the financials and appraisal. A prospective buyer sees the marketing package. Same link, different views, without maintaining separate folders.
- Gating. Access can require an NDA first, captured and timestamped against a named person before anything opens.
- A record. Who opened what, when, for how long. Both a diligence signal and, later, evidence.
When you need one
Worth it: any competitive sale process, any capital raise with more than a handful of investors, any transaction where several parties need different slices of the same documents, anything where sensitive underwriting circulates, anything where you may later need to prove what was disclosed.
Not worth it: sending one document to one person you trust. Email is fine. Genuinely — don’t build a data room to send a floor plan.
What goes in one
Varies by deal type, but typically:
- Offering memorandum or marketing package
- Financial statements, rent roll, tenant schedule
- Title, survey, easements
- Third-party reports — appraisal, environmental, engineering
- Leases and material contracts
- Permits, zoning, entitlements
- Photography, floor plans, video
- Entity and ownership documents
What “secure” actually means here
Vendors use the word loosely. In practice it comes down to four things, and they’re what to compare:
- Control — can access be revoked?
- Traceability — can a leaked copy be tied to a person?
- Gating — can an NDA be required first?
- Visibility — do you know who read what?
Encryption at rest is table stakes; every credible platform has it. Those four differ meaningfully between products.
What they cost
Traditional M&A data rooms are priced for M&A — often per page, per user, or per project, running to thousands per deal. That model exists because it was built for corporate transactions with corresponding budgets.
Newer platforms price flat. Shrubs is free up to 2.5 GB and $39/month USD for 100 GB, with no per-user or per-deal charge. For most real estate transactions, per-page pricing is a poor fit — a single environmental report can run hundreds of pages.
Where to go next
- Sharing listing documents with buyers
- Sending an offering memorandum
- Setting up a syndication data room
- Stopping documents being forwarded
