Lease Up, Rent Soaring: Istanbul Tenants Face a Summer of Scant Options

For thousands of Istanbul tenants, the summer of 2026 is bringing a brutal reality check. As one-year rental contracts come up for renewal, landlords are demanding increases that far exceed the government-mandated 25% cap, often by simply refusing to renew and forcing tenants back into a market with precious little supply. This has pushed the affordability gap between renting and buying to its widest point in nearly a decade, leaving a generation of Istanbul residents feeling trapped between impossible rents and unattainable property prices.

The pressure comes from all sides. A steady flow of foreign capital, much of it channelled through Turkey’s citizenship-by-investment program which requires a real estate purchase of at least $600,000, continues to inflate prices in prime districts. This international demand, fuelled by persistent instability in Eastern Europe and the Middle East, is colliding with a domestic housing shortage. High inflation and supply chain issues have slowed new construction projects to a crawl, creating a perfect storm where more people are chasing fewer available flats.

The Great Squeeze: From Kadıköy to Şişli

The squeeze is felt across the city, from the historic waterfronts of the Bosphorus to the sprawling outer districts. In sought-after Asian side neighbourhoods like Kadıköy, two-bedroom flats that were renting for 35,000 TRY a month last year are now being listed for upwards of 55,000 TRY for new tenants. Landlords, aware they can achieve market rates with a new lease, are increasingly using legal loopholes to evict long-term tenants at the end of their contracts, circumventing the official cap. Tenant advocacy groups report a surge in calls from residents in areas like Şişli and Beşiktaş who have been handed non-renewal notices with little explanation.

The numbers paint a stark picture of the challenge facing would-be buyers trying to escape the rental trap. According to the Turkish Statistical Institute (TÜİK), the city-wide average sales price now exceeds $2,500 per square meter. That puts a standard 100-square-meter family apartment in a mid-range district at a quarter of a million dollars. With the Central Bank of the Republic of Turkey holding interest rates firm to combat inflation, securing a mortgage requires a substantial down payment and a monthly income that is simply out of reach for most salaried workers earning in Turkish Lira.

Navigating the Dead End

So what can a renter do when the lease runs out? The options are limited and often unappealing. The first step for many is attempting to negotiate, offering a reasonable increase above the 25% cap to avoid the cost and stress of moving. This works for some, particularly with smaller, private landlords who value a reliable tenant over maximum profit. But for most, the search for a new home is inevitable. This is forcing a geographic reshuffle, pushing families and young professionals further from the city center to districts like Kartal or Beylikdüzü, adding hours to their daily commutes.

For those facing eviction notices they believe are unjust, legal consultation is becoming more common. Under the Turkish Code of Obligations, landlords must provide a valid reason for eviction, but proving their intent is often a difficult and lengthy process. Tenant rights associations are advising residents to document all communication and seek legal aid before vacating a property. For a growing number of single professionals, the only viable solution has been to abandon the search for their own place entirely, opting instead for co-living arrangements and flat-shares, a trend once confined to students that is now a mainstream survival strategy.
