Data room for commercial real estate

Confidence and control in real estate transactions of any size

Cut through the complexity

From single assets to full portfolios — one secure space

Real estate transactions often involve multiple stakeholders and a wide range of documents — from rent rolls, lease agreements, deeds and encumbrances to technical reports and valuation models. Whether it’s a single property or a large portfolio, processes too often get slowed down by scattered communication in email threads, messy spreadsheets, and disconnected tools.

Dillien makes every transaction clearer and more structured. The platform is intuitive enough to give confidence to those new to property transactions and robust enough to meet the demands of professional asset managers, lawyers and funds. From single-property deals to large-scale portfolio transactions, Dillien is trusted every day.

Features for real estate transactions

Resolve requests

Managing request lists separately means endless updates, re-uploads, and constant context switching between sheets and systems. In Dillien, the request list is fully integrated into the platform and directly tied to the file structure, so everything can be managed in one place. Resolve requests by adding text answers and files or marking applicability directly in the platform — eliminating confusion, streamlining collaboration, and saving time.

Project management

Due diligence involves many stakeholders, parallel workstreams, and tight deadlines. Dillien helps everyone stay aligned and communicate — both internally and across the table — with built-in tools for project management and collaboration. Assign responsibilities and tasks, set deadlines, track progress, and trigger automatic reminders for outstanding tasks — ensuring clear oversight, less manual coordination, and a faster path to closing.

Q&A

Enhanced Q&A, where questions, answers, and supporting files appear both in request-specific threads and on the Queries page, giving you full visibility. Everything happens directly in the data room, in the right context — ensuring clear communication and a more efficient process for all stakeholders.

Multi-bidder mode

When multiple buyers are involved, you can manage them all within a single data room — without duplicating or maintaining parallel rooms. Control exactly which documents, folders, and answers each buyer can access, ensuring sensitive information is only shared with the right parties. This reduces manual work, minimizes risk, and keeps you fully in control of the process.

Export

Export what you need — from single files to the complete data room — with just a few clicks. The export function generates a structured package of selected content — whether files, requests, Q&A, noted concerns, or activity logs — which you can store in your own archive and keep available for the future.
