The short-let math changed the day the law did
For years, an Istanbul or Antalya apartment let by the night printed gross yields that long-term tenancies could not touch. That spread is still real, but it is no longer free. Since 1 January 2024, Turkey has run every short-stay rental through a licensing regime, and the investors who treat that regime as a line item rather than an afterthought are the ones still earning the spread.
The instrument is Law No. 7464, formally the Law on the Leasing of Residential Properties for Tourism Purposes. The Turkish Grand National Assembly adopted it on 25 October 2023, and it came into force on 1 January 2024. It created the country's first dedicated permit system for Airbnb-style letting, and as of 2026 it is being actively enforced through field inspections, fines, and license revocations rather than sitting on the books as a paper requirement.
This piece looks at the regime the way a landlord underwrites a deal: as a set of inputs that move net yield up or down. The permit is one input. The 100-day rule is another. The penalty ladder is a tail risk you price in. And the unanimous-consent requirement is the single variable that decides whether you should build a short-let portfolio one objecting neighbor at a time or simply buy into a building that already clears it.
What the permit actually gates
Before you sign a single short-term lease, you need a tourism rental permit certificate (izin belgesi) from the Ministry of Culture and Tourism. The rule is sequencing, not paperwork at leisure: the certificate must exist before the first guest contract, not after the first booking.
Only the property owner, or the holder of a limited real right over the unit, may apply. Tenants cannot apply, and neither can the booking platforms. You file through Turkey's e-Devlet (e-Government) portal with identity verification, the title deed (tapu), and the consent package described below. Once granted, the Ministry issues a plaque (levha) reading "Tourism Purpose Residence" that must be displayed at the property entrance.
From an underwriting view, the permit converts a fuzzy regulatory risk into a fixed, knowable cost and a fixed lead time. That is good news. The bad news is everything that sits between you and the certificate.
The 100-day rule and what it does to revenue
The law applies to leasing a dwelling to the same tenant for 100 days or less. That is the regulatory definition of a short-term tourism rental. Any single lease that runs longer than 100 days to the same tenant falls outside Law 7464 entirely and is treated as an ordinary long-term tenancy, which needs no tourism permit.
For an investor, the 100-day line is a strategy fork, not a footnote:
- Stay inside the line and you keep the nightly model, the seasonal pricing power, and the higher gross yield, but you carry the full permit, plaque, tax, and guest-reporting load.
- Cross the line with a single 100-plus-day lease and you drop into the unregulated long-term track, shedding the permit burden but also the premium pricing.
Many portfolios will end up mixed: peak-season nightly letting under the permit, shoulder-season medium-term lets that deliberately exceed 100 days to a single tenant. Modeling the two tracks side by side, rather than assuming the nightly number all year, is where realistic net yield comes from.
The penalty ladder you price as tail risk
Operating without a permit is not a slap on the wrist. The fines escalate, and the escalation is what makes informal letting uninvestable at any serious scale.
Renting short-term without a permit draws TRY 100,000 per residence for the first violation, with a 15-day window to obtain the permit. Continue letting unlicensed past that window and the fine rises to TRY 500,000, then to TRY 1,000,000 for further continuation. The statutory range runs from TRY 100,000 to TRY 1,000,000. Note that one legal commentary frames the top TRY 1,000,000 tier as tied to repeated unlicensed use rather than a clean third strike, so treat the ladder as directionally correct and confirm the exact trigger against the Regulation text before relying on it.
The penalties do not stop at the owner. Advertising or promoting an unlicensed unit carries TRY 100,000 to TRY 500,000. Failing to display the Ministry plaque is fined TRY 100,000, plus TRY 500,000 if it is still missing after a 15-day cure period. And the platforms themselves are exposed: an intermediary such as Airbnb must remove an unlicensed listing within 24 hours of a Ministry request or face TRY 100,000 per residence. In practice that platform liability is why your listing simply vanishes if your paperwork lapses, which means the penalty risk and the revenue risk are the same risk.
Here is the cost stack an investor should carry in the model:
| Item | Amount (TRY) | Nature | Yield impact |
|---|---|---|---|
| Short-let without permit, 1st violation | 100,000 per unit | One-off fine | Wipes weeks of net income |
| Continued unlicensed letting | 500,000 | Escalated fine | Wipes a season |
| Further continuation | 1,000,000 | Top-tier fine | Wipes a year-plus of net |
| Advertising an unlicensed unit | 100,000-500,000 | One-off fine | Stacks on top of letting fines |
| Missing Ministry plaque | 100,000 (+500,000 after 15 days) | Curable fine | Avoidable with one plaque |
| Failure to report guests (KBS) | up to 500,000 | Recurring exposure | Per-incident, easy to trip |
| Accommodation tax | 2% of accommodation charge | Ongoing tax | Direct margin drag |
| Income tax on rental income | ~15%-40% progressive | Ongoing tax | The largest net-yield input |
The single largest number in most models is not a fine at all; it is income tax. A 2024 Council of State (Danıştay) ruling reclassified frequent Airbnb-style activity as commercial income rather than passive rental income, which can change how the income is taxed and reported. Combined with the 2% accommodation tax, the tax line, not the permit fee, is what separates a headline gross yield from a sober net one.
The variable that decides build vs buy
For a single apartment, the hardest gate is not the form or the fee. It is consent. The permit requires a unanimous decision of all flat owners (kat malikleri) in the building. In a multi-building complex, only the owners of the building that contains your unit must agree, but within that building a single objecting owner can block your permit outright.
Think about what that does to a build strategy. Buy a scattered apartment in an older block of mixed owner-occupiers and you are one grumpy neighbor away from a unit you cannot legally let by the night. The consent requirement is, in effect, a veto sold to people who have no stake in your yield.
Two structural escapes change the calculus, and both push investors toward buying into the right building rather than retrofitting the wrong one:
- The serviced-building exception. A building whose management plan (yönetim planı) explicitly permits short-term tourism rentals, and that provides reception, security, and daily cleaning, can obtain permits without the unanimous-consent requirement and without the 25% cap. A purpose-built, short-let-friendly complex effectively pre-clears the hardest gate for every buyer.
- The multi-unit cap. In a building with more than three independent sections, one owner may hold permits for at most 25% of the units. Cross five permitted units to a single owner in one building and you also need a workplace/business license (isyeri acma ve calisma ruhsati). For anyone planning more than a couple of units, the building's structure caps your ambition before your capital does.
Put together, the consent rule, the serviced-building exception, and the 25% cap tilt the rational investor away from assembling units one consent fight at a time and toward acquiring in buildings engineered, or zoned in their management plan, for compliant short-let from day one. Permit-ready stock carries a premium for a reason: it converts a contingent, neighbor-dependent income stream into a bankable one.
The operating load after you are licensed
The permit is the start of compliance, not the end. Once licensed, you gain access to the Kimlik Bildirim Sistemi (the identity notification system) and must report every guest's identity to law enforcement within 24 hours of check-in. Miss that and the fine can reach TRY 500,000. For a nightly-turnover unit, that is a recurring operational task, not a one-time setup, and it is the kind of obligation that pushes solo landlords toward professional management.
Foreign and non-resident owners face exactly the same permit, plaque, consent, and guest-reporting obligations as resident owners. Advisory sources also report that overseas owners are commonly required to appoint a local legal representative or proxy in Turkey to manage compliance; that point comes from property-advisory commentary rather than primary legal text, so treat it as practical guidance and confirm it for your own structure. Either way, a non-resident underwriting Turkish short-let should budget for local management as a near-certainty, not an option.
How to underwrite a Turkish short-let in 2026
The regime rewards investors who model it honestly. A defensible approach:
- Price two revenue tracks. Nightly letting under the permit for peak demand, and a 100-plus-day medium-term fallback that exits the regime when nightly demand thins.
- Put the permit, plaque, and management in fixed costs. These are knowable and small relative to the asset; they are not the risk.
- Put tax at the center. The 2% accommodation tax plus progressive income tax, with the commercial-income reclassification in mind, is the dominant net-yield input.
- Treat consent as an acquisition filter. Prefer serviced buildings or blocks whose management plan already allows tourism letting; discount or avoid stock where a single neighbor holds a veto.
- Respect the 25% cap when scaling. Spread permitted units across buildings rather than concentrating them, unless you intend to take on a business license.
- Keep the penalty ladder out of the model. The fines should be a risk you never trigger, not a cost you absorb. If a deal only works while unlicensed, it does not work.
Law 7464 did not kill the Turkish short-let trade. It professionalized it. The nightly premium still exists for owners who clear the permit, hold a compliant building, and price the tax honestly. What the law removed is the easy version: the informal, unlicensed, neighbor-irritating let that used to flatter a spreadsheet. For a disciplined investor, that is a feature, not a setback. A licensed market with a real barrier to entry is a market where the operators who do the work keep the yield, and where amateurs no longer compete the nightly rate down to nothing.
The practical takeaway is that the building is now part of the asset thesis. Two units with the same square meters and the same view can carry very different legal earning power, depending entirely on whether one sits in a serviced, permit-ready block and the other depends on a hostile owners' meeting. Underwrite the consent position, the management plan, and the tax exposure before you underwrite the nightly rate, and the spreadsheet will tell you the truth about net yield instead of the fantasy.
Liberalsun tracks permit-ready and serviced-building inventory for exactly this reason: in a licensed market, the building you buy decides the income you can legally earn.
