Turkey's priciest and strangest properties: Bosphorus yalis, islands for sale and cave houses

Turkey · October 20, 2026

A waterfront mansion with a EUR 100 million tag, islets that were listed for sale and cave houses: what the press reported, what could not be confirmed and what it means for a normal buyer.

Turkey is a country of extremes in property: wooden mansions on the Bosphorus whose asking prices are counted in tens of millions, whole islets that have been put up for sale, and houses carved into volcanic rock for the price of a small flat elsewhere. Headlines about them are easy to find, but the details are often thin. This article collects what the press has reported, says when it was reported, and marks what we could not confirm. It is general information, not advice, and these are not offers: nothing here is available through us.

The Bosphorus yalis: asking prices, not registry records

A yali is a waterfront mansion on the Bosphorus, usually built of wood or stone with its own jetty. According to an AFP report carried by Arab News and Malay Mail in October 2018, there were around 600 of them along the strait, and about 60 were then for sale. The same report said buyers were almost never Turkish and were often from the Gulf.

The most famous one is the Erbilgin Yali in Yeniköy. Wikipedia calls it the most expensive yali and says Forbes listed it in 2007 as the fifth most expensive house in the world with a USD 100 million price tag. Turkish press in April 2013 reported that the owner wanted EUR 100 million and had turned down an offer of USD 85 million.

How to read a record headline

In March 2015 several Turkish outlets reported that this yali had sold for EUR 100 million to a buyer from Qatar and called it the most expensive home ever sold in the country. A later report said it had not been sold at all but given as a gift. We could not find a land-registry record for either version, so the price and the buyer remain unconfirmed.

The lesson applies to any celebrity or record home:

  • A price in a headline is usually an asking price or a rumour, not a registered sale.
  • Different outlets can report different buyers and prices for the same house.
  • Only the land registry shows what was actually recorded, and it is not public in the way a news article is.

For that reason we do not list homes of public figures in this series unless a reliable outlet and date can be named.

Islands that were put up for sale

Turkey's press has reported islets and islands on the market more than once. Daily Sabah reported in December 2019 that Karaca Island, off Marmaris in Muğla province, had first been listed at TL 210 million and was cut to TL 145 million after months without a buyer. Reports in Hürriyet Daily News and Daily Sabah have also mentioned islets off Ayvalık, Dikili and Bodrum, among them Çiçek, Kalem and Rabbit islands. We found no island listing from 2026, so we cannot say what is on offer now, and the old prices are history, not a guide.

Whether a foreigner can buy an islet is a separate question that a news story rarely answers. A government investment-office guide says that:

  • Foreigners cannot acquire property in military forbidden zones and security zones.
  • A foreigner can hold at most 30 hectares in total in Turkey and no more than 10% of a given district.
  • Ownership passes only with a title deed signed at the land registry, not with a notarised promise.

Many coastal and island areas can be affected by military or protection rules, and some land is owned by the state. We did not find a clear rule for islets, so a lawyer must check the registry and the military clearance for the specific parcel before anything is paid.

Cave houses and heritage homes: the other extreme

At the opposite end are the houses of Cappadocia, carved into rock or built in stone. An undated property article quoted a restored cave house with one main bedroom in Göreme at EUR 121,000, a cave house of about 200 square metres in Uçhisar at up to USD 200,000, and a 209-year-old eight-bedroom house in Ürgüp at GBP 62,000. Treat those numbers as an old illustration only: they are undated and we found no current sale price of a cave hotel. What does not change is the character of these properties: heritage rules, old structures and the need for a technical survey. Our guide to cave and heritage houses to restore and the article on ruins in Turkey go into the details.

What this means for a normal buyer

  • The record and the island are rarely your market. Most buyers purchase an apartment or a villa, and the same checks matter for all of them.
  • Ownership is proved by the title deed. A reservation receipt or a sales promise is not a registered title.
  • A valuation report from a licensed appraiser is required for sales involving foreigners, and the declared price in the deed should match the real price.- Land near the coast or in sensitive areas can be affected by military clearance, so ask for it before paying a deposit.
  • Prices and costs in the ordinary market are in property prices and buying costs in Turkey, and the checks for an existing home in the resale checklist.
  • Do not rely on a listing shown on social media or by a messenger-only agent; check the agent and the owner independently.

FAQ

Can foreigners buy an island in Turkey? We did not find a clear rule. Foreigners face limits on size and cannot buy in military or security zones, and an islet may be state or protected land, so a lawyer must check the specific parcel.

Is the Erbilgin Yali really the most expensive house in Turkey? It is widely described that way, but the reports of its price and sale conflict and we found no registry record.
