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 compulsory appraisal by a Capital Markets Board (SPK) licensed valuer, 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.

• An SPK-licensed valuation report is mandatory for every sale to a foreign national — roughly USD 300–500, issued in three to seven business days — and must exist before the transfer completes.

• 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. A negative answer is a permanent bar on that parcel, 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, though foreign buyers usually end up paying all of it; total closing costs run 7–10% on resale property and 8–12% or more on new-build subject to VAT.

• 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 are not evidentiary — insist on an extract pulled within 24 to 48 hours of the transfer appointment, 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: they are limited rights in rem that are formally registered, and under Article 1008 of the Turkish Civil Code they are entered in the pledge and mortgage section, 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 acquiring someone else's debt with the apartment. 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 remedy is a deed cancellation lawsuit — years of litigation 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: a neighbour's long possession can mature into a claim under the rules in 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: a negative result is a permanent bar on that parcel, and because the restriction attaches to the land rather than the buyer, no change of purchaser or structure cures it. (Turkish companies under foreign control are the exception — see below — because their acquisitions inside these zones do require prior permission.) Risk concentrates along the Aegean and Mediterranean coasts, the Antalya hinterland and southeastern Anatolia. 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 — a list that covers well over 180 states — 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; in coastal districts with heavy foreign ownership the real headroom is much smaller than the figure suggests and the ceiling is a live constraint. 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 specific statutes — principally the Petroleum Law, the Tourism Encouragement Law and the Industrial Zones Law — 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; 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 is often impossible to mortgage, billed on construction-rate utility tariffs 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: stock predating the modern seismic codes, or standing in an area designated under Law No. 6306 on the transformation of areas under disaster risk, can be scheduled for demolition and rebuilding at the flat owners' own cost.

Valuation, Transfer Tax and the 2026 Base-Value Reset

The Mandatory SPK Appraisal

Since 2019, every sale of real estate to a foreign national requires a valuation report from an appraiser licensed by the Capital Markets Board (SPK), and the price declared on the tapu cannot fall below the appraised figure. The rule addresses anti-money-laundering concerns and price manipulation in the citizenship-by-investment channel; in practice it also tells the buyer whether they are overpaying. Budget USD 300–500 and three to seven business days, and commission it early enough that a low appraisal 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. In current market practice foreign buyers usually bear the whole 4%; it is a commercial point worth negotiating rather than a fixed cost. The base is the declared price, which may not be lower than the property's registered tax value and, for a foreign buyer, not lower than the SPK appraisal. 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. On resale property the total commonly lands between 7% and 10% of the price; on new-build subject to VAT it can reach 8–12% or more. Understating the declared price to reduce the 4% is not a saving — it is a tax offence, it caps the acquisition cost deductible against any future capital gain, and it can compromise a citizenship or residence 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.

The promise-to-sell agreement must be executed before a notary to be valid, and it should be annotated on the developer's title so the buyer's claim binds third parties — that annotation lapses 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 the appraisal must support the USD 400,000 threshold, the tapu carries an annotation prohibiting resale for three years, and the payment chain must be documented end to end — undeclared escrow flows, third-party payments or an appraisal that does not withstand scrutiny will each sink an otherwise compliant application, as our citizenship practice sees regularly. A residence permit can also be obtained on the strength of a purchase, but the minimum property value is fixed by administrative regulation rather than by statute and has been revised more than once, and some districts are closed to new foreigner registration altogether — both points have to be checked against the position in force on the day, not against 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 a spouse and children, so a foreign will that ignores them will be cut back. 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. Foreign nationals from over 180 countries may acquire real estate in Turkey without a pre-existing residence permit, subject to nationality-based and parcel-based restrictions — military zones, total area caps per province, and a 30-hectare nationwide cap for individuals. A residence permit can subsequently be obtained on the basis of the property purchase itself, provided the asset meets minimum value thresholds set annually by the Ministry of Interior.

Is the TAPU sufficient evidence of ownership in Turkey?

Yes — but only the original, currently registered TAPU verified at the TKGM. Photocopies and outdated extracts are not evidentiary. Buyers should always insist on a fresh land registry extract issued within 24–48 hours of the transfer, as encumbrances can be added at any time prior to registration in the buyer's name.

What happens if the property falls within a military zone?

The TAPU transfer is blocked permanently. The buyer's deposit, if not protected by a conditional escrow arrangement or contractual clawback clause, may be lost. Competent counsel verifies zone status during pre-contractual due diligence — never after signing — and structures the deposit to be returnable upon adverse military clearance.

Can a foreign company own real estate in Turkey?

Yes, through a Turkish subsidiary or branch — though foreign-controlled Turkish companies face additional procedural requirements under Article 36 of the Land Registry Law. The acquisition must be approved by the relevant Governorship and aligned with the company's stated business purpose, and any subsequent change of shareholder control may trigger fresh approval requirements.

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

Existing owners face higher annual property tax (emlak vergisi) and higher exposure on capital gains tax in any future disposal. The reset does not retroactively affect taxes already paid on prior transfers, but it does materially change the planning calculus for owners considering refinancing, gifting, or estate restructuring within the next twelve months.

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

Not automatically. The investment must satisfy SPK appraisal at or above the threshold, be held for a minimum of three years with a TAPU annotation prohibiting earlier disposal, and be supported by complete provenance-of-funds documentation. Procedural error at any stage — undeclared escrow flows, undocumented payment chains, or a non-compliant appraisal — can disqualify an otherwise compliant investment.

Is a valuation report mandatory for foreign buyers in Turkey?

Yes. A report prepared by an appraiser licensed by the Capital Markets Board (SPK) is required for every sale to a foreign national and must exist before the title deed transfer can complete. It usually costs USD 300–500 and is issued within three to seven business days. The price declared on the tapu cannot fall below the appraised figure, so the report also fixes the base used for the 4% transfer fee.

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 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. In current market practice foreign buyers usually end up paying the whole 4%, so it is worth negotiating. The base cannot be below the property's registered tax value or, for a foreign buyer, the SPK appraisal. Added to the valuation, the Land Registry revolving-fund charge, notary and sworn-translator fees, compulsory earthquake insurance and legal fees, total closing costs commonly reach 7–10% on resale property and 8–12% or more on new-build subject to VAT.

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 far smaller than the figure suggests and it bites in coastal districts with heavy foreign ownership. 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.
