Value-led districts on the European side continue to lead on yield, while prime Bosphorus addresses lead on appreciation. Why the two rarely coincide — and how to check a yield figure before you trust it.
Rental yield is the most quoted and least interrogated number in Istanbul property. It appears in brochures without a date, without a source, and almost always without saying whether it is gross or net. So before naming districts, it is worth being precise about what the number is.
The number, defined
Gross yield is annual rent divided by purchase price. It is easy to calculate, easy to inflate, and describes an outcome no landlord has ever actually received.
Net yield is what remains after the costs of ownership. Subtract, at minimum:
- Building dues (aidat) where the landlord bears them — in large complexes with pools, gyms and 24-hour security these are the largest single deduction, and they are charged whether or not the unit is let.
- Vacancy — the weeks between tenancies. A unit let eleven months of the year has already lost roughly 8% of its gross.
- Management and letting fees, if you are not in Istanbul to handle it yourself.
- Maintenance and periodic refurbishment. Rental units need repainting and appliance replacement on a cycle.
- Tax on rental income, and annual property tax.
The gap between gross and net is not a rounding error. Any advisor who quotes you a yield and cannot immediately produce the assumptions behind it is quoting a marketing figure, not an investment one.
Why value districts lead on yield
Yield is a fraction, and the purchase price is the denominator. This single fact explains most of the pattern.
In prestigious districts the price rises faster than the achievable rent, because the pool of tenants who can pay a prime-district rent is far smaller than the pool of buyers who want a prime-district address — and a good part of that buyer demand is about the address itself, not about what it earns. The denominator runs away from the numerator.
In value-led districts the reverse holds. Entry prices are lower, while rent is set by ordinary, deep, local demand — families and workers who need somewhere to live near employment and transport, and who are relatively indifferent to prestige. This is why the western and north-western European side, districts such as Beylikdüzü, Başakşehir, Esenyurt and Küçükçekmece, has consistently produced the stronger income ratios: it is where accessible new supply was built, and where tenant demand is broad rather than narrow.
Why prime addresses lead on appreciation instead
The same districts that yield poorly often grow best, and for a structural reason: their supply cannot expand. Bosphorus waterfront, conservation-protected low-rise neighbourhoods, and central districts with no developable land left are physically fixed. Sarıyer along the northern Bosphorus is the clearest case; Beşiktaş and Şişli in the centre, and Kadıköy on the Asian side, behave similarly.
Scarcity is what you are buying, and scarcity pays out on sale rather than monthly. Judging such a property by its yield is measuring the wrong thing — but so is buying a value district expecting a resale windfall. Decide which of the two you actually need before you compare properties at all.
The middle, which is where most people should look
Districts with genuine local economies — Kadıköy and Ataşehir on the Asian side, Şişli and Kağıthane on the European — do neither job spectacularly and both respectably. Ataşehir is worth singling out for income buyers: it grew around office and financial employment, so its tenant demand comes from people who work nearby, which is a sturdier base than tourism or foreign-buyer flow.
The under-rated advantage here is liquidity. When you sell, there is a domestic buyer for the property, not only an international one — and that is what determines whether you can exit at a price you choose rather than a price you accept.
Short-let: higher gross, different business
Furnished short-term letting posts a higher gross figure, and it is a genuinely different proposition rather than a better version of the same one. It carries meaningful vacancy seasonality, materially higher management cost, faster wear, and regulatory requirements that apply to short-term tourist rental specifically. Treat it as operating a small hospitality business, not as collecting rent. If nobody is going to run it properly on the ground, the long-let figure is the one that will actually reach you.
Five questions before you accept any yield figure
- Gross or net? If the answer is not immediate, assume gross.
- Signed or asking? Ask what comparable units in the same building actually rented for, not what they were listed at.
- What is the aidat? Get the monthly figure in writing before you calculate anything.
- What vacancy is assumed? Twelve months of occupancy is an assumption, not a fact.
- In which currency, over what period? A yield in lira and a yield in dollars are different numbers, and only one of them is the one you will spend.
The summary
Value-led districts on the European side continue to lead on income; prime Bosphorus and central addresses continue to lead on appreciation; the established middle trades a little of each for liquidity. That structure is stable. The specific percentages are not — they move with prices, rents and the exchange rate, so ask for current figures on the specific building you are considering rather than relying on a district-level average from any article, including this one.
If you would like the net calculation run properly on a particular property — actual signed comparables, the building's dues, and a realistic vacancy assumption — that is part of what we do before a client commits.
