Real Estate Due Diligence in Turkey: TAPU, Zoning and Risk Areas

Real estate due diligence in Turkey decides whether a cross-border purchase becomes an asset or a capital trap. Whether the deal is a Bosphorus apartment, a commercial floor in İstanbul or a plot on the Aegean coast, the title deed the seller shows you discloses only a fraction of the exposure. A bank mortgage, an annotation from a pending lawsuit, a parcel inside a military zone, a building that never received its occupancy permit, or the 2026 base-value reset can each destroy value long after the keys change hands.

The Turkish system carries structural risks that do not exist in most home jurisdictions: parcel-level military and security screening, a valuation by a Capital Markets Board (SPK) licensed appraiser that Land Registry circulars require on sales to foreign nationals, encumbrances recorded in registry sections that sit apart from the ownership entry, and nationality-based caps on how much land a foreigner may hold. A broker discloses none of it, and almost none of it can be fixed after registration. This guide sets out the sequence our real estate practice in Turkey applies before any money leaves the buyer's account.

Key Takeaways

• Ownership passes only at the land registry, when your name replaces the seller's on the tapu (title deed). A signed sale agreement transfers nothing.

• Land Registry circulars require a valuation report from an SPK-licensed appraiser on property sales to foreign nationals, and it must be ready before the transfer; the requirement is administrative, not statutory, so check the current circular.

• Military and security screening runs at parcel level: the Land Registry Office checks the parcel against coordinate data supplied in advance by the Ministry of National Defence and the Ministry of Interior. While the zone stands, a negative answer bars a foreign individual from that parcel; it is not a delay.

• The 2026 reappraisal of land unit values opens a four-year cycle running to 2029, but the increase is capped: Law No. 7566 of 4 December 2025 limits the 2026 taxable value to three times the 2025 value, and that capped figure also sets the base for the transfer fee and the annual property tax.

• The transfer fee is 4% of the declared price — by statute 2% from the buyer and 2% from the seller, and who bears which half is a matter for the contract; budget separately for the valuation, registry charges, notary and translation, earthquake insurance and legal fees.

• A foreign individual may hold up to 30 hectares nationwide, a ceiling the President is empowered to double, and foreign nationals together may not exceed 10% of the privately owned (özel mülkiyete konu) surface area of any single district.

Ownership Passes at the Registry, Not at the Contract

Under Article 705 of the Turkish Civil Code, ownership of immovable property is acquired by registration. The tapu is not a private document exchanged between the parties; it is a state record held by the General Directorate of Land Registry and Cadastre (TKGM). The costliest error foreign buyers make is treating a signed contract, a paid deposit or handed-over keys as a transfer of ownership. Our guide to buying property in Turkey as a foreigner walks through the Land Registry Office appointment itself.

Confirming the Registered Owner and the Tapu Extract

Obtain a current extract of the tapu record (tapu kayıt örneği) and confirm that the person presenting themselves as the seller is the registered owner. Photocopies and old extracts show only what the register said on an earlier day — pull a fresh extract as close to the transfer appointment as possible, because entries can be added at any point until your name is registered. Powers of attorney granted abroad, inherited shares still standing in a deceased owner's name and undivided joint ownership among heirs are routine complications that can leave a seller unable to convey clean title on the day.

Reading the Mortgage and Annotation Sections, Not Just the Ownership Entry

The register is not a single list. Ownership sits in the main register (kütük). Mortgages (ipotek) are not annotations at all: Article 1008 of the Turkish Civil Code lists pledge rights among the rights that are registered, and under Article 31 of the Land Registry Regulation (Tapu Sicili Tüzüğü) they are entered in their own mortgage column, separate from the annotations column. That annotations column (şerhler), governed by Articles 1009 to 1011, carries a different family of entries — tenancy annotations (kira şerhi), contractual pre-emption and repurchase rights (önalım, vefa), preliminary registrations, provisional injunctions (ihtiyati tedbir), attachments, and other restrictions on the owner's power of disposal. Each section has to be pulled and read separately, because a buyer who checks only the ownership entry misses both of the others: a clean ownership record can still carry a mortgage in the pledge section, or a long tenancy annotation that defeats any vacant-possession plan. These entries follow the asset, not the previous owner, so skipping this screen means buying an apartment that still answers for someone else's debt. Each must be discharged before completion or expressly dealt with in the contract, with price held back until it is. When a defect surfaces afterwards, the remaining route is litigation, such as a deed cancellation lawsuit, to undo what an hour at the registry would have prevented.

Matching the Legal Description to the Building on the Ground

The deed describes a block and parcel (ada/parsel) and, in a condominium, a defined land share. Physical reality does not always match. Unauthorised extensions, enclosed balconies and converted roof floors are common in older stock, and a surveyor's confirmation that the registered description matches what is being sold protects the buyer from inheriting an unpermitted structure, a municipal fine or a demolition order. On land and rural parcels check occupation as well as boundaries: on unregistered land, or registered land whose owner cannot be identified from the register, twenty years' possession can found a registration claim under Article 713 of the Civil Code — see our guide to adverse possession and the 20-year rule.

Public-Law Restrictions That Can Block the Purchase Entirely

A separate layer of public-law rules decides whether a foreign national may acquire this parcel at all. They bite at registration and are not negotiable, which is why due diligence must finish before the deposit is paid.

Military and Security Zone Screening

Turkey restricts foreign acquisition in military forbidden zones, military security zones and special security zones around borders, installations and strategic infrastructure. Under Article 35/5 of the Land Registry Law, the maps and coordinate values of those areas are supplied in advance — by the Ministry of National Defence for military forbidden, military security and strategic zones, and by the Ministry of Interior for special security zones — to the ministry the land registry administration reports to, and title transactions are then carried out on the basis of that data. So the screen happens electronically at the Land Registry Office against pre-loaded coordinates; there is no case-by-case referral to a military command and no separate military permit for an individual buyer to wait for. The answer is nonetheless binding for a foreign individual: Law No. 2565 bars foreigners from acquiring property in second-degree military forbidden zones (Article 9(b)) and lets the President bar them from areas designated for proximity to such zones or other strategic reasons (Article 28), and no contract term cures that. (Turkish companies under foreign control follow a different route — see below — because their acquisitions inside these zones require prior permission.) Confirm status before signing, and structure the deposit to return automatically if clearance fails.

Country Eligibility, Individual Caps and the District Limit

Reciprocity is the wrong test, and has been since 2012: the reciprocity condition for foreign individuals was removed from Article 35 of the Land Registry Law by Law No. 6302. Whether your own country sells property to Turkish nationals is no longer the question. Under Article 35 as it now stands, eligibility depends on being a national of a country designated by Presidential decision, and no residence permit is needed first. Three quantitative limits then apply. One foreign individual may own up to 30 hectares nationwide, and the President is expressly empowered to raise that per-person ceiling to double, so the figure in force should be checked at the time rather than assumed. Foreign nationals collectively may not hold more than 10% of the privately owned (özel mülkiyete konu) surface area of any given district — not 10% of the district's total area, which is a far larger number. And under Article 35/3 the President may, where the national interest requires it, separately limit, suspend or prohibit acquisitions by reference to country, person, geographic region, duration, number, ratio, type or area. One further trap on land: a foreign buyer of an unbuilt parcel must submit the project they intend to develop to the relevant Ministry within two years, and the approved project is recorded against the parcel and monitored. Anyone assembling more than one asset should model all of this at the outset.

Acquiring Through a Turkish Company

A foreign company cannot simply register Turkish real estate in its own name. Under Article 35 of the Land Registry Law, commercial companies with legal personality formed under the laws of their own country may acquire immovables and limited rights in rem only within the framework of special statutes, and foreign legal entities that are not commercial companies cannot acquire at all. The practical route is therefore a company incorporated in Türkiye. Once such a company is 50% or more foreign-held, or foreign shareholders can appoint or remove the majority of its managers, it falls under Article 36 of the Land Registry Law: the acquisition must serve the activities stated in its articles of association, and the company applies through the governorship where the property sits; property inside military forbidden or military security zones requires permission from the General Staff or a command it authorises, and property inside a special security zone requires the permission of the governorship where the property sits; and a later share transfer that takes foreign control to 50% or more brings the same regime into play. Corporate ownership can suit larger positions and sidesteps the individual hectare cap, but it adds annual compliance and changes the tax treatment on exit — the trade-offs are in our comparison of buying property through a company versus personally, and the structuring sits with our corporate and commercial team.

Zoning, Permits and Building Compliance

Three municipal documents govern whether a building may lawfully be used and resold: the zoning status (imar durumu), the construction permit (yapı ruhsatı) and the occupancy permit or iskan (yapı kullanma izin belgesi). A property without a valid iskan can be hard to mortgage and materially harder to sell at a normal price. Request the imar durumu from the municipality and compare the approved project with the building as it stands; deviation from the approved plan is the usual reason an iskan was never issued. Building age matters too: under Article 5 of Law No. 6306 on the transformation of areas under disaster risk, the owners of a building found to be risky are given up to ninety days to demolish it, and if the authorities demolish it instead the costs are collected from the owners in proportion to their shares.

Valuation, Transfer Tax and the 2026 Base-Value Reset

The SPK Appraisal

Land Registry circulars require a valuation report from an appraiser licensed by the Capital Markets Board (SPK) on property sales to foreign nationals. The requirement is administrative rather than statutory, so the current circular should be checked before the appointment. In practice the report also tells the buyer whether they are overpaying; commission it early enough that a low figure can still be renegotiated rather than absorbed.

The 4% Transfer Fee and the Real Cost of Closing

The title deed transfer fee is 4% of the declared sale price, but it is not a single 4% charge on the buyer. Under the Fees Law (Law No. 492) the tariff levies 20 per mille — 2% — separately on the transferor and on the transferee, so the statutory position is 2% each. Who bears which half is a commercial point for the contract rather than a fixed cost. Under Article 63 of the Fees Law the base is the declared price, which may not be lower than the property's registered tax value; on a property held under kat irtifakı the fee runs on the whole price. That is one line of the budget: add the SPK valuation, the revolving-fund charge at the Land Registry Office, notary and sworn-translator fees, compulsory earthquake insurance (DASK), utility transfer costs and legal fees. Understating the declared price to reduce the 4% is not a saving: Article 63 has the shortfall assessed afterwards with a tax-loss penalty of one times that amount, and an understated deed can undermine a citizenship application built on the same file.

What the 2026 Reset Changes

Minimum square-metre unit values for land are reappraised by the valuation commissions once every four years, and the appraisals made during 2025 govern 2026 through 2029. Those appraisals were dramatic in many districts, but the resulting increase is capped by statute rather than left to run: Law No. 7566 of 4 December 2025 rewrote Provisional Article 23 of the Property Tax Law so that the 2026 assessed value of a building, plot or parcel cannot exceed three times its 2025 value, and General Communiqué Series No. 89, published on 31 December 2025, works the calculation through with examples. The cap reaches beyond the annual property tax (emlak vergisi), because the same provision directs that taxes, fees and other financial obligations calculated on assessed values must use the capped figure — which includes the minimum base for the 4% title deed fee. For 2027, 2028 and 2029 the capped values are simply uprated by the annual revaluation rate. The reset is not retroactive to tax already paid, but for existing owners it changes the arithmetic on refinancing, gifting to family and any restructuring planned in the coming year.

Off-Plan Purchases: The Highest-Risk Category

Off-plan acquisitions carry the worst risk profile in the market. The buyer signs a promise-to-sell agreement (satış vaadi sözleşmesi) before the developer has obtained the iskan, sometimes before construction has started, then pays instalments against a building that does not yet exist. The recurring failure modes are developer insolvency, deviation from the approved architectural project, unauthorised modifications that later block the iskan, and zoning reclassification mid-project.

Under Article 237 of the Turkish Code of Obligations a promise to sell immovable property is valid only if made in official form, which for a promise to sell means a notarised contract, and it should be annotated on the developer's title so the buyer's claim binds third parties — under Article 26 of the Land Registry Law the registry deletes that annotation of its own motion if the sale is not completed within five years. Alongside it: payments tied to construction milestones certified by an independent engineer, bank guarantees for sums paid ahead of delivery, and indemnities for iskan delay and material deviation with a clear refund mechanism if the project stalls. A deposit paid into the developer's general account against a one-page reservation form has no protection at all.

Structuring the Purchase and Protecting the Money

Deposits, Escrow and Powers of Attorney

The deposit is where most foreign buyers lose leverage. Hold it conditionally — in a lawyer's client account or bank escrow — with automatic return if military clearance fails, if an undisclosed encumbrance surfaces, or if the appraisal comes in below the agreed price. Where the buyer cannot travel, the transfer can be completed under a power of attorney; that power should name the specific parcel and the specific acts authorised, and it should never be granted to the seller, the developer or anyone in their orbit.

If the Purchase Supports a Citizenship or Residence Application

Where the property also serves an immigration objective, the file has to satisfy a second reviewer. On the citizenship by investment route, Article 20(2)(b) of the Regulation on the Implementation of the Turkish Citizenship Law requires property worth at least USD 400,000 (or the foreign-currency equivalent) with a three-year no-sale annotation on the title; under the same article the currency must be sold to a bank in Türkiye before the transaction and the value is measured at the Central Bank rate on the determination date, so the payment chain should be documented end to end — our citizenship practice reviews that file. A short-term residence permit may also be granted to a property owner under Article 31(1)(b) of Law No. 6458, but the nature and value of the property that supports one are set by the Ministry under Article 31(6), not by the statute itself, so check the position in force on the day, not a figure quoted in an older article.

Succession Exposure Most Buyers Never Consider

Immovable property located in Türkiye passes under Turkish succession law whatever the owner's nationality and wherever the will was made. Turkish forced heirship (saklı pay) reserves defined shares to descendants, parents and a surviving spouse (Civil Code, Article 506), and a disposition that exceeds the disposable portion can be cut back by an action for reduction (tenkis, Article 560). Ownership structure and estate plan belong in the same conversation, before purchase — see our guide to cross-border inheritance and estate planning.

Due diligence in Türkiye is not a formality run alongside the transaction — it is the transaction. The registry check, the parcel screening, the permit file, the appraisal and the payment structure all have to be complete before the deposit moves, because after registration the buyer's only remaining route is litigation. Send us the tapu details, the listing or the developer's contract, and we will tell you what is on the record before you commit anything.

Common questions about property due diligence in Turkey

Can a foreigner buy property in Turkey without a Turkish residence permit?

Yes. Article 35 of the Land Registry Law does not require a residence permit before purchase; eligibility depends on being a national of a country designated by Presidential decision, subject to parcel-based restrictions such as military zones, the 10% cap on foreign individuals' holdings in any one district and a 30-hectare nationwide cap per individual. A short-term residence permit may then be granted to a property owner under Article 31(1)(b) of Law No. 6458; the nature and value of qualifying property are set by the Ministry of Interior under Article 31(6).

Is the TAPU sufficient evidence of ownership in Turkey?

What counts is the land registry record kept by the TKGM, not a paper copy: a photocopy of a title deed or an old extract shows only what the register said on an earlier day. Pull a fresh land registry extract as close to the transfer appointment as possible, as encumbrances can be added at any time before registration in the buyer's name.

What happens if the property falls within a military zone?

A foreign individual cannot acquire a parcel inside a second-degree military forbidden zone (Law No. 2565, Article 9(b)) or inside an area the President has closed to foreigners under Article 28 of that Law, and the land registry processes transactions against the zone maps supplied under Article 35(5) of the Land Registry Law. Whether a deposit comes back depends on the contract, so verify zone status before signing and make the deposit returnable if clearance fails.

Can a foreign company own real estate in Turkey?

Not directly, except under special statutes: Article 35 of the Land Registry Law confines companies formed under foreign law to acquisitions under special laws. The practical route is a company incorporated in Türkiye. If it is 50% or more foreign-held, or foreign shareholders can appoint or remove the majority of its managers, Article 36 applies: the acquisition must serve the activities in its articles of association, the application goes through the governorship where the property sits, acquisitions in military forbidden, military security or special security zones need prior permission, and a later share transfer that takes foreign holdings to 50% or more brings the same rules into play.

How does the 2026 base-value reset affect existing owners?

Existing owners face higher annual property tax (emlak vergisi) and a higher minimum base for the title-deed fee on any future transfer, within the cap in Provisional Article 23 of the Property Tax Law. The reset does not retroactively affect taxes already paid on prior transfers, but it does change the planning calculus for owners considering refinancing, gifting, or estate restructuring.

Is property purchased through a USD 400,000 investment automatically eligible for Turkish citizenship?

Not automatically. Article 20(2)(b) of the Regulation on the Implementation of the Turkish Citizenship Law requires property worth at least USD 400,000 (or the foreign-currency equivalent) that carries condominium ownership or a condominium easement, or is arsa-registered land with a building, bought with a three-year no-sale annotation on the title. The currency must be sold to a bank in Türkiye, and by the bank to the Central Bank, before the transaction, and the Ministry of Environment, Urbanisation and Climate Change makes the determination. A file that falls short on any of these points does not qualify.

Is a valuation report mandatory for foreign buyers in Turkey?

In practice, yes. Land Registry circulars require a report prepared by an appraiser licensed by the Capital Markets Board (SPK) on property sales to foreign nationals, and it has to be ready before the title deed transfer. The requirement is administrative rather than statutory, so check the current circular; the statutory floor for the 4% fee base remains the registered tax value under Article 63 of the Fees Law.

What is the title deed transfer fee in 2026, and who pays it?

The statutory transfer fee is 4% of the declared sale price, and under Tariff No. 4 of the Fees Law (Law No. 492) it is charged as 2% on the seller and 2% on the buyer rather than 4% on one side; who bears which half is for the contract, so it is worth negotiating. Under Article 63 the base cannot be below the property's registered tax value. Budget separately for the valuation, the Land Registry revolving-fund charge, notary and sworn-translator fees, compulsory earthquake insurance and legal fees.

Is there a limit on how much property a foreigner can own in Turkey?

Yes. A single foreign individual may acquire up to 30 hectares nationwide — a ceiling the President is empowered to double — and foreign nationals collectively may not hold more than 10% of the privately owned (özel mülkiyete konu) surface area of any one district. That is not 10% of the district's total area, so the real headroom is smaller than the headline figure suggests. Reciprocity was abolished for individuals in 2012; what matters now is whether your country is on the list designated by Presidential decision, and the President may separately restrict or suspend acquisitions by nationals of particular countries. Each parcel must be checked individually before any commitment is made.
