Istanbul apartments: where foreigners should buy

Istanbul is the deepest property market in Turkey and the one where the choice of district matters most. A flat in Beşiktaş and a flat in Esenyurt are different products with different tenants, different building ages and different risks. This guide compares five districts that foreign buyers ask about, gives the 2026 price picture, and puts the earthquake checks first because they matter more here than anywhere else in the country. For the national picture see best areas to buy in Turkey.

The districts in short

• Beşiktaş (European side, on the Bosphorus): central, expensive, much older stock, strong demand from professionals and expats. Many buildings are old, so the building check matters.
• Şişli (European side, business core): offices, shopping and metro, a mix of old and renovated buildings, steady rental demand.
• Kadıköy (Asian side): a lively residential and cultural district with ferries and metro, popular with locals who want to live rather than invest.
• Esenyurt (outer European side): large, newer, cheaper housing estates and a big rental market with families and workers. Lower price per flat, but less prestige and more supply.
• Beylikdüzü (outer European side, on the Marmara shore): new estates and shopping centres, well connected by the metrobus and highway, popular with families. We found no verified current price figure for it.

None of these is simply good or bad. Central districts hold value and rent to professionals; outer districts give more space for the money and a larger pool of tenants.

What prices say in 2026

Endeksa and Emlakjet data for August 2026 give an average Istanbul home price of about 7.4 million lira, roughly 137,000 euro, up about 27% in lira and down about 3.4% after inflation. The citywide average of about 60,400 lira per square metre in January 2026, roughly 1,100 to 1,200 euro, mixes every district and building age. Our best areas guide quotes higher figures for the city centre, about USD 3,100 per square metre with a wide range, because it measures newer central projects, not the whole city. We did not find verified current per-square-metre prices for individual districts, so we do not give any. Ask for closed sales in the same building and see Turkey property prices and buying costs for fees. The title-deed tax is 4% of the declared value; a licensed valuation report and DASK earthquake insurance are required.

Earthquake checks before you buy

Istanbul sits near the North Anatolian fault, and the 1999 Kocaeli earthquake changed the building rules. Use these checks.

• Building age. Municipal inspection programmes have prioritised buildings from before 2000. A building from the 1990s or earlier needs a structural assessment before you commit, not after.
• The hazard map. AFAD, the disaster agency, runs the national earthquake hazard map (tdth.afad.gov.tr). It shows the hazard of the area and its soil, not the strength of your building, so it is one input, not a clearance.
• The building itself. Ask for the occupancy permit (iskan), the construction licence, any engineering or inspection report and whether the building has been strengthened. Ask whether it has been designated as a risky structure or is in an urban transformation plan under the law on areas at disaster risk (Law 6306), which can force renovation and costs on owners. Your lawyer should check the registry, not just the seller's word.
• Soil and neighbours. Flats on soft ground, in dense old streets, or in buildings with ground-floor shops that removed supporting walls are higher risk.
• Insurance. DASK, the compulsory earthquake insurance, covers the structure up to a limit and does not replace a safe building or contents cover. Confirm the cover and the exclusions.

Rental income

Endeksa data for August 2026 put the Istanbul average rent at about 45,500 lira a month against the 7.4 million price, a gross yield near 7.4%. Global Property Guide figures for the first quarter of 2026, seen only in a search summary, reported about 10.7% for a one-bedroom in Esenyurt, about 8.4% for a two-bedroom in Şişli and 4.2% to 5.3% in Kadıköy. Treat them as reported, in lira, before tax. See rental yield and investment. Short lets need a permit and the consent of all owners, see short-term rental rules.

Citizenship and foreign ownership

Turkish citizenship by investment through real estate requires at least USD 400,000, with a three-year no-sale annotation on the deed. We confirmed the figure in secondary sources, which report that the investment authority restated it in March 2026, but not on the official text, so verify the current threshold and conditions before you plan around it. A residence permit is a different and lower route, see golden visa and citizenship. Foreigners may own limited land per person, cannot buy in military or security zones, and the land registry checks with the military before a sale; Istanbul has several such areas, which can delay a purchase. Some neighbourhoods are also closed to new foreign registrations, so check the address before relying on a residence permit.

For Russian-speaking buyers

Istanbul has a large Russian-speaking community, and agents, notaries and translators who work in Russian are easy to find. The usual steps apply: passport, Turkish tax number, a bank account, the valuation report, and payment through the banking system with a title-deed price that matches the real price. Banks ask about the source of funds, so prepare documents and comply fully. Residence permit questions are decided by the migration authority (goc.gov.tr). If you buy from the EU, a notarised power of attorney lets a lawyer act for you, see mortgages for foreigners for financing.

FAQ

Which district of Istanbul is best for a foreigner? There is no single best; Beşiktaş and Şişli suit those who want central, Kadıköy suits living on the Asian side, and Esenyurt or Beylikdüzü suit a lower budget and a family rental market. Is Istanbul safe to buy in given earthquakes? Risk is real; buy a newer building, check the occupancy permit and any risk designation, get a structural report for older stock and insure through DASK. What is the minimum for Turkish citizenship? Reported at USD 400,000 of real estate with a three-year no-sale annotation; verify the current official text. Can foreigners buy anywhere in Istanbul? Not in military or security zones, and the registry checks before a sale. Is Esenyurt a good investment? It shows high reported gross yields in lira, but supply is large and the result in euros depends on the exchange rate. Does a purchase give a residence permit? It may support one if the conditions are met, but it is a separate application.
