What Nine is
Nine is a free, open-source desktop application for managing residential rental properties. It targets real estate investors, property managers, and landlords handling up to nine properties. The app stores property profiles with photos and documents, tracks status, and provides portfolio analytics. Users can manage prospects, tenants, leases, digital lease creation and acceptance, deposits, renewals, and expiration reminders. Financial tools generate recurring rent invoices, record payments through multiple methods, apply configurable late fees after a grace period, and produce reports and payment histories. Maintenance features cover requests, vendor assignments, repair costs, scheduled inspections, a 26-item checklist, and PDF reports. Notifications include lease warnings and late-fee notices, with optional SendGrid and Twilio accounts for email and SMS. Nine uses a local SQLite database encrypted with SQLCipher AES-256 and OS keychain password management. Manual or scheduled backups and staged restore previews are included. Linux AppImage and Windows downloads are listed.
