Nine review
A focused free option for landlords managing up to nine properties on Windows or Linux.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Nine is an open-source desktop property management application for landlords, real estate investors, and independent property managers with small residential portfolios. It supports up to nine properties and brings property profiles, tenant and prospect tracking, digital leases, recurring rent invoicing, payment recording, maintenance requests, inspections, notifications, backups, encryption, and role-based access controls into one local application. Its solo and small-business focus makes it a practical fit for self-managed rentals rather than larger property management companies.
The feature set is broad for a small desktop application. Property records can include photos and documents, while lease workflows cover creation, acceptance, renewal, and termination. Maintenance tracking includes vendors and costs, and inspections support scheduling, checklists, and PDF reports. Nine also connects with SendGrid and Twilio for notification-related workflows. Its local SQLite storage, backups, database encryption, and role controls add useful administrative safeguards for a small team, although the product does not offer AI features.
Nine’s main trade-off is its narrow deployment and portfolio scope. It runs on Windows and Linux as desktop software, so it is less suitable for teams that need browser access, mobile workflows, or a broader cloud ecosystem. The payment workflow focuses on recurring invoices and recording payments rather than a stated tenant-facing portal or online rent collection system. Support is available through email and a community, which fits an open-source product but may require more self-direction than a larger commercial platform. Choose Nine for a small, locally managed portfolio; consider another option if you need more than nine properties or tenant-facing online operations.
