For many international buyers, the TTB is unfamiliar because it is not a normal sales document, not a title deed, not a bank receipt, and not the same as the price agreed with the seller. It shows the property investment amount that can be accepted for Turkish Citizenship by Investment.
A citizenship purchase is not judged only by the asking price. The land registry checks several values, including the official deed value, the sale promise value where relevant, bank payment receipts, the Foreign Exchange Purchase Certificate, and the TTB.
If those records do not support the required threshold, the citizenship file can run into problems even if the buyer believed they paid enough.
The TTB confirms the investment amount that can be accepted for citizenship purposes. This is different from an estate agent’s valuation, developer price list, bank transfer, or private agreement. Those records may support the file, but the TTB is the formal valuation-based certificate used inside the land registry process.
In 2025, 1,688,910 homes were sold nationwide. Foreign buyers purchased 21,534 homes, equal to 1.3% of total residential sales. Turkey’s land registry system also records more than 59.7 million parcels, 25.7 million independent sections and over 333,000 foreign ownership records.
What the Tutar Tespit Belgesi Shows
The TTB shows the accepted investment amount for the relevant real estate in a citizenship transaction. It is created as an attachment to the official valuation process and sent digitally through the correct systems. A physical TTB handed in by the buyer or seller is not accepted. The land registry uses it to check whether the property amount meets the legal requirement before later citizenship checks continue.
TTB, WebTapu, TADEBİS and TAKBİS
The TTB process is digital. A valuation request for citizenship is made through the WebTapu or TADEBİS system. TADEBİS is the real estate valuation information system. TAKBİS is the land registry and cadastre information system used in the official title deed process.
In a citizenship purchase, the TTB is sent into TAKBİS/WebTapu through the designated route. This digital transfer reduces reliance on paper documents. Buyers should not rely on a PDF or informal copy unless the document has been properly sent through the required system.
Is TTB Needed for Every Foreign Buyer?
No. This is a common misunderstanding. Ordinary foreign property purchases do not generally require an appraisal report simply because the buyer is foreign. That general requirement was removed.
TTB becomes relevant when the purchase is connected to Turkish citizenship through real estate. A foreign buyer purchasing a holiday apartment, family villa or rental property with no citizenship plan may not need a TTB. A buyer using the property to apply for citizenship usually will.
There are also listed exemptions from TTB confirmation for certain transactions involving public institutions and real estate investment partnerships, although the General Directorate can still request a TTB in some exempted cases.
Which Values Must Reach the Citizenship Threshold?
The required amount is $400,000 or equivalent. For the land registry check, the relevant values must separately support the required amount. These include the official deed value, sale promise value where applicable, total payment receipts, and the amount confirmed by TTB.
A buyer should not treat one strong document as enough. A bank receipt above $400,000 does not fix a TTB below $400,000. A high advertised price does not fix a lower official deed value. The safest file is one where all key values align clearly above the threshold.
Step by Step: How the TTB Process Works
The buyer confirms that the purchase is intended for Turkish citizenship.
The property is checked for legal suitability. The title deed type, seller, ownership structure, restrictions, mortgage entries and transfer position should be reviewed.
The buyer checks whether the agreed price gives enough room above the $400,000 threshold. A property priced exactly at the threshold may be risky if the Tutar Tespit Belgesi comes lower.
The TTB-based valuation request is made through WebTapu or TADEBİS for citizenship purposes.
The valuation is prepared and the TTB is generated through the system.
The buyer and adviser compare the TTB amount with the planned deed value, payment records and DAB.
If the values support the citizenship threshold, the Tapu transfer or official sale promise route can continue.
The three-year no-sale commitment is registered where required.
The documents move through the official route for the Certificate of Conformity stage.
Timing: The Six-Month Rule
The TTB cannot be treated as open-ended. For citizenship-related transactions, the period between the TTB and the relevant application should not exceed six months. If this period passes, the valuation report forming the basis of the certificate must be renewed.
This can affect buyers who reserve early, delay completion, change payment dates, or wait too long between valuation and transfer. The practical advice is simple: order the TTB at the right time, not too late and not so early that it expires before the citizenship step is ready.
Example One: TTB Below the Purchase Price
Imagine a buyer agrees to purchase a property in Bodrum for $420,000. The seller, contract and payment plan all refer to $420,000. The buyer believes the citizenship threshold is safely covered. The TTB then confirms only $392,000 as the accepted investment amount.
This creates a serious problem. Even though the buyer planned to pay more than $400,000, the accepted TTB amount does not reach the citizenship threshold. The buyer may need to renegotiate, choose a different property, add another qualifying property, or stop before completion.
Example Two: Stronger File with a Buffer
A second buyer agrees to purchase two apartments in Istanbul for a total of $465,000. The TTB confirms $438,000. The bank receipts, DAB and official deed values also support an amount above $400,000.
This file is cleaner because the buyer is not relying on a borderline valuation. A buffer does not guarantee approval, but it reduces one of the main valuation risks.
TTB and DAB Are Different
TTB and DAB are often mentioned together, but they do different jobs. DAB, or Döviz Alım Belgesi, proves that foreign currency was sold through the Turkish banking system for the property purchase. TTB confirms the accepted investment amount for citizenship purposes.
A buyer may have a valid DAB and still have a weak TTB. A buyer may have a strong TTB but still need correct bank receipts. For citizenship, the documents need to work together without inconsistencies.
TTB and the Title Deed Value
The TTB does not replace the Tapu. It also does not decide the title deed transfer tax by itself. TKGM states that an amount identified in the TTB is not binding for title deed fee purposes under the current legislation.
The TTB has a specific role. It confirms the accepted citizenship investment amount. It is not a general tax valuation for every purpose.
Common TTB Problems
The most common problems include ordering the wrong valuation type, leaving the TTB until the last stage, choosing property too close to $400,000, assuming the seller’s price will be accepted, ignoring title issues, using payment records that do not align, and confusing the TTB with a general appraisal.
Other risks include buying shared property, using a sale promise contract incorrectly, paying part of the price outside the documented route, or forgetting that the TTB may need renewal after six months.
Before paying a reservation deposit on a citizenship property, ask:
Will this property be used for Turkish citizenship?
Has a TTB route been planned?
Is the asking price comfortably above $400,000?
Could the official value come in lower than the price?
Will the DAB, receipts, deed value and TTB align?
Is the property eligible for the three-year annotation?
Are there title deed restrictions or debt entries?
Is the completion timeline realistic within the six-month period?
What happens if the TTB is too low?
Citizenship Property Checks Before Completion
For foreign buyers, TTB is not something to fear. It is a checkpoint that helps show whether a Turkish property can support the citizenship route. The risk comes from treating it as a formality.
A strong citizenship purchase should start with the property’s legal position, realistic market value, documented payment route, and the buyer’s long-term plans. The property should be worth owning after the citizenship file is complete.

Can I rely only on bank receipts?
No. Bank receipts are important, but the TTB, DAB, deed value and other documents must also support the required amount.
How long is a TTB valid?
