Imagine viewing an apartment in Istanbul, liking what you see, and receiving a polished offer with a price and payment plan attached. Before committing, one comparison still matters: are existing owners selling comparable units in the same development, and on what terms?
The developer’s offer shows what it is asking for its unit. On its own, it does not tell you what another buyer might eventually pay you.
At IDEX Real Estate, we start by examining that gap — comparing total acquisition cost against credible alternatives, then assessing potential net returns and resale risk.
A property can be an excellent home without being an attractive investment at its asking price. The reverse is equally true: a completed apartment from a developer can be the right choice when the comparison and the numbers support it.
A Question Worth Asking Before You Sign
If you bought this apartment today and put it back on the market without any change in conditions, what price would comparable evidence support?
This tests the entry gap — it is not a requirement to sell quickly. A longer hold may make sense, but the starting point still matters.
Three Prices That Are Not the Same Thing
- Developer list price: The advertised figure under a specific offer and payment structure. Ask for the final price after discounts and incentives.
- Resale asking price: What an owner hopes to receive — which may differ from what is accepted after negotiation.
- Verified comparable transaction price: Stronger evidence of what a buyer actually paid, adjusted for differences in property, timing, and transaction circumstances.
We verify that comparable listings are current, genuinely available, and not duplicate advertisements for the same unit. Where completed-sale data is unavailable, we identify comparisons as asking-price evidence — not achieved market prices.
When We Advise Against Buying Completed Stock from a Developer
We advise against it when the developer’s price is materially above comparable alternatives, the additional benefits do not justify the premium, and the investment depends on uncertain future appreciation to close the gap.
Construction costs, financing, marketing, and profit targets may influence a developer’s asking price. They do not, by themselves, establish what the property is worth to another buyer. That requires a market comparison.
The best starting point is the same development. Are existing owners selling comparable units? If not, the search moves to competing projects with similar characteristics.
A meaningful comparison accounts for: net internal area and layout; floor, outlook, and orientation; condition, finishes, and included fittings; tenancy status and vacant possession; title status, restrictions, and obligations; payment terms and total buyer costs; and the date and reliability of each comparable used.
An advertised price is not evidence of a completed transaction. A multiyear installment total should not be compared directly with a cash price without accounting for the timing of those payments.
If a material premium remains after these adjustments, the buyer needs to understand its effect on the investment. When the comparison reveals a substantial, unjustified premium, that needs to be clear before a purchase is recommended.
How the Entry Premium Affects Returns
A hypothetical example: a purchase at TRY 10 million, with a comparable resale value of TRY 8 million at entry. The value would need to rise 25% just to recover the purchase price — before transaction costs, and without counting rental income.
The entry price also shapes rental yield. Two equivalent apartments each generating TRY 400,000 in annual net income, acquired at TRY 8 million and TRY 10 million respectively, produce yields of 5% and 4% on acquisition cost — assuming identical income and expenses.
These are illustrative calculations, not estimates of current Istanbul returns. A proper assessment covers net rents and net sale proceeds after all costs, across the planned holding period, in the investor’s chosen currency.
Your Developer May Also Be Your Competition
If the developer is still selling comparable units at exit, prospective buyers will compare your property with its remaining stock. Installment plans or incentives may make the developer’s offer attractive even at a similar price. This applies whether you originally bought from the developer or from a previous owner — what matters is the competing supply when you want to sell.
The developer selling out removes one source of competition. It does not guarantee recovering the premium paid. Other owners may list simultaneously, competing projects may emerge, or demand may shift.
Resale value also depends on the time available to sell. A price achievable with an extended marketing period may not be available when cash is needed quickly. Exit estimates should specify a selling timeframe and include a faster-sale scenario, which may require a lower price.
Time alone is not an investment strategy. A longer hold needs its own financial case: realistic rental income, ownership costs, and the ability to keep capital committed. Also test whether the investment remains acceptable if the property does not appreciate, vacancy runs long, or completion is delayed.
Three Routes Worth Comparing
1. Completed Property from a Developer
Allows inspection before purchase and reduces construction wait. Can be appropriate for investment where total cost is competitive and expected return justifies the risks and holding period.
Physical completion does not automatically mean immediate title transfer, an available tenant, or a defect-free property. Legal status, handover arrangements, and contractual protections all need to be checked.
2. Completed Property on the Resale Market
An existing owner may offer a comparable unit at a lower total cost, with the same ability to inspect before buying. Where specifications are equivalent and checks are satisfactory, this deserves serious consideration before paying a developer premium.
A lower price deserves investigation — it is not proof of a bargain. It may reflect the seller’s need for liquidity, or differences in outlook, condition, occupancy, or outstanding obligations. The discount is only meaningful once its cause and associated costs are understood.
Maintenance needs, encumbrances, and any work required before letting must be assessed. Buying on the resale market does not eliminate competition from the developer or other owners when you come to sell.
3. Off-Plan Property
May offer a price or payment structure that compensates for the construction period and risks assumed by the buyer. Due diligence should cover the developer’s delivery record, permits, contractual protections, specifications, completion date, and any restrictions on resale or assignment.
No rental income should be assumed before the property is delivered and ready to let. A developer raising its price list during construction does not establish that an existing buyer can resell at the new price.
Legal and technical due diligence matters across all three routes. The specifics differ by property and transaction.
Buying as a Home
An owner-occupier may reasonably pay more for a layout, view, or apartment that suits the family. Those are real benefits — but they are distinct from investment performance. The buyer should understand the premium being paid and its potential effect on a future sale, even when financial return is not the primary objective.
Turkish Citizenship
The real estate investment pathway to Turkish citizenship carries a minimum qualifying threshold, property and transaction requirements, and a three-year holding period. Eligibility must be assessed against the rules in force at the time of application. Neither completion nor purchasing directly from a developer establishes eligibility automatically.
Citizenship eligibility and investment value are independent assessments. A property can satisfy the legal requirements while still being priced above comparable alternatives. Purchasing does not guarantee citizenship is granted.
What to Establish Before Signing
At IDEX, we begin with four questions:
- What is the primary objective? Rental income, capital appreciation, personal use, or a citizenship application?
- How does the total cost compare? Start with equivalent units in the same development, then examine competing projects.
- What is the expected net return? Planned holding period, all costs, realistic vacancy, in the investor’s currency.
- How realistic is the exit? Who is the likely future buyer, and what will they be comparing your property against?
Ask for a written comparison showing what you are buying, the evidence supporting income and resale estimates, and the assumptions that could change the result.
