From short-term to long-term rental: what changes in the work, not just the tax

From yesterday, 1 March 2026, restrictions on short-term rentals apply in Thessaloniki's First Municipal Community, joining the freeze on new registrations in central Athens. In both places, a registration no longer survives a sale or inheritance. At the same time, the state offers a three-year income tax exemption to owners who move an empty property, or one in short-term rental, to a long-term lease of at least three years — for leases signed by 31 December 2026, with size limits and other conditions set out on the government's housing portal.

So a lot of owners and property managers are doing the sums. The tax side belongs to your accountant. What I want to look at is the part that tends to be underestimated: how the work of managing the property changes.

What gets lighter

Short-term rental is operationally intense. Every stay has a check-in, a cleaning, a laundry run, messages before and after, a review, a platform payout to reconcile, and a guest register. A busy apartment can have a hundred of those in a year.

A long lease replaces almost all of that with one tenant, one contract and one monthly payment. That is the attraction, and it is real.

What does not disappear

It moves. Long-term rental has fewer events, but each one matters more, and they are spread over years, which makes them easy to forget:

• Rent is due every month, and a missed month noticed late is hard to recover.
• Rent adjustments written into the lease happen once a year, and only if someone remembers the date.
• Repairs are now the owner's responsibility in a home someone lives in, reported at odd hours, and they need a record.
• The lease ends, or needs renewing, three years later, when nobody remembers what was agreed.
• For the tax exemption, conditions such as the lease duration have to hold for the whole period. Breaking them can cost the benefit, so the dates need watching.

In short: a holiday let fails loudly, the same week. A long lease fails quietly, over months.

A system built for both

The property management system we built handles long and short-term leases side by side, including sublets. Rent schedules are generated from the lease; expected rent is compared against rent received, with arrears; indexation is applied automatically; maintenance tickets are tied to expenses; and alerts flag leases that are about to expire.

For an owner or a manager moving part of a portfolio from short to long-term, that matters, because for a while you run both, and the two need different kinds of attention.

Before you switch a property

1. Get the tax answer first. Whether the exemption applies depends on the property's history and details. Ask your accountant.
2. Put the lease's key dates in a calendar on the day you sign it: first rent, annual adjustment, end date, and any date that matters for the tax benefit.
3. Decide how rent will be checked each month, and by whom. "I'll see it in the bank" is how two months go by.
4. Agree how the tenant reports repairs, and keep a log per property.

The honest version

One apartment moved to a long lease needs a calendar and a folder, not software. A manager moving dozens, while still running holiday lets for other owners, needs the dates and money for both kinds of rental in one place. Tell us about your portfolio.
