Buying Off-Plan Property in Istanbul, Turkey | Contract Guide 2026

Buying an Off-Plan Property in Istanbul, Turkey: The Most Important Contract Clauses

Buying an off-plan property in Istanbul can be an attractive option for international buyers and investors who are looking for new residential projects, flexible payment plans and the possibility of purchasing a unit at an earlier stage of development.

However, buying a property that is still under construction is fundamentally different from buying a completed apartment.

When purchasing a completed property, the buyer can normally inspect the actual unit, review its physical condition and evaluate the finished product. With an off-plan property, many of the characteristics of the future apartment depend on the sales contract, technical specifications, architectural plans, delivery schedule and developer's obligations.

For this reason, the contract should never be treated as a routine document.

Turkey's official investment guidance states that ownership of real estate is acquired through registration at the land registry. Preliminary real estate contracts do not themselves transfer ownership; rather, they represent a commitment concerning a future transfer.

What Is an Off-Plan Property?

An off-plan property is a property purchased before construction has been completed.

The project may be:

At the planning stage.

At the excavation stage.

Under structural construction.

At the finishing stage.

Near completion but not yet ready for delivery.

Istanbul has a large and diverse market for new developments, including residential complexes, high-rise projects and mixed-use developments.

The buyer may be able to select a preferred apartment at an early stage, potentially benefiting from an attractive payment schedule.

However, the buyer also assumes additional risks because the final product does not yet physically exist in its completed form.

Why Do Investors Buy Off-Plan Property in Istanbul?

Early-stage pricing

Developers may offer different prices during different phases of a project.

Early buyers may sometimes benefit from lower launch prices, although future price appreciation should never be considered guaranteed.

Flexible payment plans

Some developments offer installment plans extending over the construction period.

The buyer should examine the total purchase cost, not merely the monthly installment.

Wider unit selection

Buying early may provide greater choice regarding:

Floor.

Orientation.

View.

Apartment size.

Number of bedrooms.

Parking.

Position within the development.

Long-term investment potential

Some buyers purchase off-plan apartments for future resale or rental income.

However, any forecast regarding capital appreciation should be treated as an investment expectation rather than a guaranteed return.

Main Risks of Buying an Off-Plan Property

Construction delays

One of the most important risks is delayed delivery.

The contract should clearly address:

Delivery date.

Grace period.

Force majeure.

Compensation.

Buyer's cancellation rights.

Changes to specifications

Marketing brochures and computer-generated images do not necessarily provide the same legal protection as contractual specifications.

The materials and features that matter should be documented in the agreement or its annexes.

Area differences

The buyer should understand the difference between:

Gross Area

and

Net Area

and determine exactly how the contractual area is calculated.

Project changes

The contract may allow the developer to make certain technical changes.

The buyer should carefully determine whether these changes can affect the apartment's:

Location.

View.

Size.

Layout.

Specifications.

Facilities.

Value.

Due Diligence Before Signing

A professional purchase process should include verification of:

Developer identity.

Developer track record.

Land and project status.

Property information.

Relevant permits and approvals.

Title status.

Payment schedule.

Construction schedule.

Maintenance fees.

Cancellation conditions.

Liens and encumbrances.

Ownership transfer procedure.

Turkey's official investment guidance recommends checking potential mortgages, liens and other restrictions that could affect a property before proceeding with land registry procedures. Basic property information can also be queried through the relevant land registry and cadastral systems.

The Most Important Clauses in an Off-Plan Property Contract

Seller and Developer Information

The contract should identify the legal parties precisely.

It should include, where applicable:

Legal company name.

Registered information.

Address.

Authorized signatory.

Buyer's details.

Representative information.

The person signing on behalf of the developer should have appropriate authority.

Precise Property Identification

The contract should not simply state:

Apartment in Project X.

It should identify the unit as precisely as possible.

Relevant information can include:

Project name.

Location.

Block or tower.

Floor.

Independent unit number.

Apartment type.

Area.

Orientation.

Parking rights.

Storage rights.

Relevant common-area rights.

Apartment Number and Area

An apartment described merely as "2+1" is not sufficiently specific for practical purposes.

A development may contain many 2+1 units with different:

Views.

Floors.

Sizes.

Orientations.

Prices.

The contract should identify the exact unit and attach the relevant plans where appropriate.

Total Purchase Price

The contract should state the total purchase price clearly.

It should also clarify:

Currency.

Deposit.

Installments.

Payment dates.

Bank account.

Discounts.

Taxes.

Fees.

Additional charges.

If the price is denominated in USD or EUR but payments are made in Turkish lira, the exchange-rate mechanism should be clearly understood.

Contract Checklist

Payment Schedule

The payment schedule should be clearly incorporated into the contract.

It may include:

Initial deposit.

Construction-stage payments.

Monthly installments.

Payment at completion.

Final payment upon title transfer.

Avoid vague provisions such as:

"Payments shall be made according to construction progress."

The contract should specify the amount or percentage and the corresponding payment date or construction milestone.

Delivery Date

The delivery clause is one of the most important parts of an off-plan contract.

The buyer should determine whether the stated date is:

Binding.

Estimated.

Subject to a grace period.

Extendable under specific conditions.

The contract should also establish what happens if delivery is delayed.

Delay Compensation

A well-structured agreement should explain the developer's obligations if the property is not delivered on time.

Depending on the agreement, compensation may take the form of:

Monthly compensation.

Agreed damages.

Alternative rental costs.

A contractual penalty.

Cancellation rights.

The exact enforceability of such clauses depends on the contract and applicable Turkish law, so professional legal review is advisable.

Technical Specifications

Expressions such as:

"Luxury finishing"

are not sufficiently precise by themselves.

The contract should ideally include a detailed specification schedule covering:

Flooring.

Doors.

Windows.

Insulation.

Heating and cooling.

Kitchen.

Appliances.

Bathroom fixtures.

Paint.

Ceilings.

Security systems.

Elevators.

Common facilities.

The contractual specifications should be compared with the developer's marketing materials.

Changes to the Development

Developers may need to make certain technical changes during construction.

The contract should therefore define:

Which changes are allowed.

Their limits.

Whether the buyer must be notified.

What happens if the change materially affects the apartment.

Whether the buyer has cancellation or compensation rights.

A clause giving the developer unlimited discretion can create significant uncertainty for the buyer.

Final Area

The final constructed area may differ from the initial planned area.

The contract should specify:

Permitted variation.

Price adjustment.

Refund mechanism.

Additional payment mechanism.

Method used to determine the final area.

This is particularly important because area differences can affect the property's value.

Title Deed and Ownership Transfer

One of the most important legal concepts for international buyers is the distinction between a preliminary agreement and actual ownership.

A preliminary sales agreement does not, by itself, transfer ownership.

Ownership is transferred through the official registration process at the Land Registry Directorate.

Turkish land registry guidance also recognizes real estate sales-promise arrangements under specific conditions, but such an arrangement should not be confused with final title registration.

Mortgages, Liens and Encumbrances

The legal status of the property and underlying land should be examined.

The buyer should determine whether there are:

Mortgages.

Liens.

Attachments.

Rights of third parties.

Other restrictions.

The Turkish government's investment guidance specifically emphasizes checking such restrictions before initiating the official registration process.

Cancellation and Withdrawal

This clause is often overlooked.

The buyer should know:

Whether cancellation is permitted.

The cancellation period.

Cancellation fees.

Whether the deposit is refundable.

Refund timetable.

Developer's obligations after cancellation.

Buyer's rights in case of significant delay.

All major promises should be written into the contract rather than communicated verbally.

Refund Mechanism

If the agreement is cancelled, the contract should establish:

Refund method.

Currency.

Timing.

Applicable deductions.

Exchange-rate mechanism.

Bank account.

This can be particularly important for international buyers who pay in a foreign currency.

Force Majeure

The contract may include force majeure provisions.

The buyer should understand exactly:

Which events qualify.

How the event must be documented.

How long delivery can be extended.

Whether the buyer can cancel after a prolonged delay.

An excessively broad force majeure clause may create uncertainty regarding the delivery date.

Maintenance and Management Fees

Modern residential complexes in Istanbul may offer:

Security.

Swimming pools.

Fitness centers.

Parking.

Gardens.

Reception.

Maintenance.

Elevators.

The buyer should therefore understand the expected management fees.

Questions should include:

Is the fee monthly or annual?

Is the quoted amount fixed or estimated?

Can it increase?

Which services are included?

Parking and Additional Facilities

If the project advertises:

"Apartment with parking."

the buyer should establish exactly what that means.

Is it:

Separate ownership?

An allocated parking space?

A right of use?

Transferable?

Included in the contract?

Reflected in the official documents?

The same principle applies to storage rooms and other additional spaces.

Taxes and Expenses

The contract should clarify responsibility for:

Land registry fees.

Taxes.

Notary expenses.

Translation.

Legal fees.

Valuation-related expenses where applicable.

Management fees.

Utility connection costs.

Other project-related expenses.

A written cost estimate should be obtained before signing.

Payment to the Developer

Payments should be made through properly documented channels.

The buyer should keep:

Bank transfer receipts.

Invoices.

Payment confirmations.

Contract copies.

Annexes.

Written discounts.

Relevant correspondence.

The official Turkish investment guide also describes secure transaction mechanisms such as TAKASBANK for certain real estate transactions.

Contract Language

An international buyer should never sign a contract that they do not understand.

Depending on the circumstances, professional assistance may include:

Sworn translation.

Independent lawyer.

Legal translation.

Turkish official procedures also recognize the role of a certified interpreter when a party does not speak Turkish during relevant land registry transactions.

The objective is simple:

The buyer must understand exactly what they are signing.

Off-Plan vs. Completed Property

Is an Off-Plan Property Suitable for Foreign Investors?

It can be, but the answer depends on the buyer's objective.

For residential use

If the buyer intends to move to Istanbul soon, a completed property may be more appropriate.

For investment

An off-plan property may suit an investor with a longer time horizon who is prepared to accept construction and delivery risks.

For Turkish citizenship

Special caution is required.

Purchasing an off-plan unit does not automatically guarantee eligibility for Turkish citizenship.

According to current official investment guidance, the real estate route involves purchasing qualifying real estate worth at least USD 400,000, together with the applicable title-deed restriction and other requirements.

Therefore, anyone purchasing specifically for citizenship should verify the eligibility of the project, unit, ownership structure and transaction before making a payment.

How to Choose an Off-Plan Project in Istanbul

A structured process can help reduce risk.

Step 1: Define your objective

Determine whether you want:

Residence.

Rental income.

Resale.

Long-term investment.

Citizenship eligibility.

Step 2: Research the district

Consider:

Public transport.

Metro access.

Main roads.

Schools.

Hospitals.

Shopping centers.

Nearby developments.

Rental demand.

Competing supply.

Step 3: Investigate the developer

Review previous projects, delivery history, construction quality and reputation.

Step 4: Compare prices

Compare the property with similar developments in the same area rather than comparing it with completely different districts.

Step 5: Review the contract

Read every important clause.

Step 6: Obtain independent legal advice

The person selling the property should not necessarily be the only person advising you about its legal risks.

Step 7: Document every payment

Every payment should be traceable.

Step 8: Monitor construction

The buyer can compare actual construction progress with the contractual schedule.

Final Checklist Before Signing

Verify the developer.

Verify the property.

Confirm the exact unit.

Review the floor plan.

Confirm the area.

Review technical specifications.

Confirm the final price.

Review payment schedule.

Confirm delivery date.

Review delay provisions.

Review cancellation provisions.

Review refund mechanism.

Check liens and encumbrances.

Understand title transfer.

Confirm maintenance fees.

Confirm taxes and expenses.

Understand the contract language.

Obtain all annexes.

Obtain independent legal advice where appropriate.

Buying an off-plan property in Istanbul can provide opportunities for both residential buyers and long-term investors, particularly when the buyer carefully selects the project, developer and unit.

Nevertheless, the contract is one of the most important elements of the transaction.

The buyer should focus particularly on:

purchase price, payment schedule, delivery date, delay compensation, technical specifications, area, project changes, cancellation, refunds, title transfer, liens, maintenance fees and additional expenses.

Most importantly, a preliminary sales agreement should not be mistaken for the final transfer of ownership. Turkish official guidance confirms that ownership is acquired through registration at the Land Registry Directorate.

For foreign buyers, especially those purchasing for citizenship, resale or long-term investment, an independent Turkish real estate lawyer can provide an additional layer of protection by reviewing the project's legal status and the exact contractual terms before any substantial payment is made.
