What Is My Property Worth in Istanbul? A Guide to Real Estate Valuation for Foreign Owners

If you own property in Istanbul and you’re thinking about selling, the first question you’ll ask is the same one every owner asks: what can I actually get for it?

It sounds straightforward. But in Türkiye, and especially in Istanbul, property valuation is more nuanced than in most markets. Exchange rates shift, neighbourhood trajectories diverge dramatically, and the gap between asking price and achievable sale price can be significant. Understanding how your property is valued — and by whom — is the first step to selling at the right number.

The Turkish lira factor is real, but it cuts both ways

Foreign owners often make the mistake of anchoring to what they paid. If you bought an apartment in Beşiktaş in 2018 for $180,000, you might look at today’s lira-denominated valuations and feel uncertain about what that translates to. The Turkish property market primarily quotes in US dollars or euros for foreign buyers, which offers some protection against lira inflation — but it also means that your property’s value in hard currency is affected by where global demand sits at any given moment.

Eden Turkey offers a property valuation service for $50, which gives you a solid, realistic picture of what your property is worth in current market conditions before you commit to a sale. What this means practically is that Istanbul property values are best assessed in USD or EUR, not Turkish lira. Any serious buyer from abroad, and most serious local buyers in the premium segment, will negotiate in foreign currency. Keep that in mind when you’re building your price expectations.

Location within Istanbul is everything — and the differences are stark

Istanbul is not one market. It’s more like ten markets stacked on top of each other. A 120 square metre apartment in Nişantaşı will command a very different price per square metre than the same floor plan in Esenyurt — we’re talking about a difference of anywhere from two to five times the per-square-metre value, depending on the specific street, the building age, and the view.

In 2024 and into 2025, the strongest resale demand in Istanbul has consistently been in a handful of districts. Beyliktüzü and Esenyurt on the European side have seen high transaction volumes driven by affordability and infrastructure investment, particularly the metro extensions. But for foreign resales specifically — where your most likely buyer is another international purchaser — the premium European districts tend to hold value better.

Şişli deserves a particular mention. It sits at the heart of European Istanbul, well-connected by metro, surrounded by established commercial and residential infrastructure, and it has consistently attracted both local upgraders and foreign buyers looking for a central base. Resale demand there holds up well even when other districts soften, partly because the rental market is strong and buyers know it. If you own in Şişli, you’re in a good position. If you’re considering a purchase before an eventual resale, it remains one of the more reliable bets in the city.

Kadıköy and Moda on the Asian side are where resale liquidity also tends to be strong. If you own a sea-view property in Üsküdar or Beykoz, that view is a genuine asset, not just a lifestyle feature. Bosphorus and Marmara views routinely add 20 to 35 percent to achievable sale prices compared to equivalent inland units in the same building. This is one of the few markets in the world where view really does command that kind of premium consistently.

The flipside: if your property is in a newer mass-development area further from the city centre, you may find the resale market thinner. Many of these projects sold heavily to foreign buyers between 2018 and 2022, and the resale market for them can be competitive with new-build inventory from the same developer or adjacent projects. That doesn’t mean you can’t sell — it means your pricing needs to be sharp and your marketing targeted.

How valuations actually work in Türkiye — and what to watch for

There are a few different ways to approach valuation as a foreign seller in Türkiye.

The official ekspertiz raporu is mandatory for property transactions involving foreign nationals, and it’s produced by a licensed appraiser registered with the Capital Markets Board (SPK). These reports use a comparable sales methodology, looking at recent transactions in your neighbourhood for similar property types. They’re reasonably accurate in high-transaction areas, but in thinner markets — a single-floor villa in a less-traded area, for example — they can miss the mark.

The ekspertiz value is not the same as market value. Banks use it as a floor for mortgage lending purposes, and it tends to be conservative. Don’t mistake a low ekspertiz as evidence that your property is worth less than you think — it’s a floor, not a ceiling.

For a realistic picture of what your property can sell for, you want a combination: the official report plus a genuine comparative market analysis from a reputable local agent who is actually active in your district. Ask them to show you completed sales — not listings, not asking prices — in the last six months. Listings in Istanbul can sit for months at inflated prices; completed transaction data is what actually tells you where the market is.

One more thing worth knowing: if you’ve owned your property for fewer than five years, you’ll be subject to capital gains tax in Türkiye on the difference between your purchase price (adjusted for inflation) and your sale price. After five years, that tax disappears. This doesn’t affect your property’s value, but it absolutely affects your net proceeds, so factor it into your calculations before you set a price.

The bottom line is this: Istanbul is a market where well-located, well-presented property in the right districts sells. Foreign owners who come in with realistic, evidence-based pricing and a clear understanding of who their buyer is tend to transact within a reasonable timeframe. Those who anchor to hope prices typically wait much longer — or don’t sell at all.

If you’re serious about selling, start with the data. Know your district, know your comparable sales, and price accordingly.
