Property in Kocaeli

Kocaeli is the province just east of Istanbul, wrapped around the Gulf of Izmit, with Izmit as its capital. It is one of Turkey's main industrial regions, yet the forested slopes of Kartepe and nearby Lake Sapanca offer green, quiet places to live. It suits people who work in the region, commuters to eastern Istanbul and buyers looking for a weekend home in nature.

Living in Kocaeli

Kocaeli is a working province. Factories, ports and logistics centres line the gulf, and many people commute between its towns and the Asian side of Istanbul. Life in the towns is practical and less hectic than in the big city, with hospitals, universities, shopping centres and seafront parks, and housing generally costs less than in Istanbul.

Nature is never far away. The hills behind the coast are covered in forest, the Kartepe ski resort draws visitors in winter, and villages such as Maşukiye, with their streams and trout restaurants, are popular weekend spots, including with visitors from the Gulf.

Getting around is straightforward: the province sits on the main motorway and rail corridor between Istanbul and Ankara, high-speed trains stop in Izmit, the Osmangazi Bridge crosses the gulf towards Bursa, and Sabiha Gökçen Airport on Istanbul's Asian side is the closest major airport.

Where to look

  • Izmit is the provincial centre, with services, the seafront and good transport links.
  • Başiskele, on the southern shore of the gulf, offers newer housing and a quieter pace with views across the water.
  • Kartepe rises from the gulf towards the mountains near Lake Sapanca and is popular for villas and holiday homes.
  • Towns at the western end of the province, such as Gebze, suit people who work on the Istanbul side.

What to check

The Marmara region is an active earthquake zone, and Kocaeli was hit hard in 1999. Make the building's permit date, the ground survey and its compliance with the current earthquake code your first questions, before the view or the finishes. In the mountains, ask how the access road copes with snow and how far the nearest shops and schools are. For new projects, ask for the building permit and a delivery date written into the contract. If you will commute to Istanbul, try the motorway at rush hour first, as traffic around Gebze is often heavy.

Guides about Kocaeli

Guides
  • Close to Istanbul without the crowds: Bursa, Kocaeli and Sakarya for Arab buyers

    Bursa, Kocaeli and Sakarya are three provinces near Istanbul with lower prices and more nature. Sakarya is known for Lake Sapanca and its summer homes; Kocaeli combines the industrial city of İzmit with the nature of Kartepe overlooking the lake; and Bursa is a large green city at the foot of Mount Uludağ, with the modern district of Nilüfer. Istanbul is reached by motorway, high-speed train and sea ferry. Because the region was hit by the 1999 earthquake, choose modern buildings built to the new regulations.
