Compstash - 2026 Pricing, Features, Reviews & Alternatives

Compstash is private commercial real estate comparable property data management software designed for brokers, brokerages, corporate real estate teams, institutional investors and research professionals. The platform enables centralized storage, organization and controlled sharing of closed deal comparables within a single database while maintaining complete ownership and privacy of all submitted data. Compstash employs a privacy-first model that prevents indexing, resale or distribution of user data to third parties or competitors. The software supports diverse roles including retail, industrial and office brokers, team managers, portfolio directors, research units and investment groups.

The platform includes bulk upload and import functionality that preserves existing spreadsheet histories without data loss or reformatting requirements. Users can implement customizable tagging structures to classify comparables by property type, submarket, corridor or any user-defined criteria aligning with established workflows. Location tagging provides a map interface for geospatial filtering by radius or corridor and visualization of market coverage. Granular permission controls allow assignment or revocation of view, edit and export rights by user role, asset type or project.

Branded report generation creates client-ready documents in Excel or PDF formats with one click using customizable logos and layouts. The interface is designed for intuitive use by administrative or virtual assistant support staff with minimal training. Data export operations guarantee retrieval of complete databases irrespective of subscription status. The system maintains data confidentiality by refraining from integration with external market intelligence services and avoids any form of data indexing or sharing beyond explicitly granted access.

Compstash operates as a web-based service with no software deployment, complex onboarding or IT infrastructure requirements. Initial configuration can conclude within minutes of account creation and allows immediate migration of existing comp listings. The platform functions as a standalone repository specialized for internal data management rather than external data exchange.
