Never miss a landlord deadline: ΕΝΦΙΑ, ΜΙΔΑ and lease declarations
The expensive mistakes in property are missed dates. Nineflat turns ΕΝΦΙΑ, ΜΙΔΑ, and lease-declaration deadlines into self-renewing reminders that come to you by email and SMS.
The expensive mistakes in property aren't dramatic — they're missed dates. A lease declaration filed late (€100+ penalty), an ΕΝΦΙΑ instalment forgotten, a ΜΙΔΑ confirmation that slipped your mind. Each one is small; together they're the difference between a calm year and a stressful one. Nineflat turns those deadlines into reminders that come to you.
Every recurring deadline in one place Open Reminders. Settlements, maintenance, inspections, and compliance dates all live here, each with its own schedule and next due date.

The deadlines that matter to Greek landlords are built in:
- ΕΝΦΙΑ — property tax, per property, every year.
- Lease declaration / ΜΙΔΑ confirmation, tied to each active agreement.
- Custom reminders for anything else — boiler service, insurance renewal, rent review.
Reminders that actually reach you Each reminder fires an email (and SMS on paid plans) ahead of time, so you act before the deadline, not after the penalty. Mark it done and it reschedules itself for next year — no calendar maintenance.
Why this beats a phone calendar
- Attached to the property, not your memory. Reminders carry the property and the agreement, so you know *which* flat the ΕΝΦΙΑ or declaration is for.
- Shared with your team. A property manager or accountant with access sees the same deadlines — nothing depends on one person's phone.
- Self-renewing. Annual obligations come back automatically.
