Rental Vacancy Rates in Istanbul Hit Record Lows, Sending Competition Soaring

Istanbul’s residential rental market is tighter than ever, with vacancy rates plunging below 2.1% in June and would-be tenants jostling for a dwindling supply of available apartments—especially in sought-after zones like Besiktas and Kadikoy.

This fierce competition is not just driving up prices, but fundamentally reshaping how—and where—Istanbulites can afford to live. Renters face substantial hurdles as owners weigh multiple offers for even modest flats. The squeeze comes at a moment when post-pandemic migration, a new wave of foreign investment, and demographic shifts are converging, compressing an already tense market.

From Besiktas to Kadikoy: Scarcity Pushes Prices Up

The steepest competition is visible in central districts. On bustling Barbaros Boulevard in Besiktas, agents from real estate firm Remax Corner say standard 2+1 apartments listed for 35,000 TL monthly seldom stay on websites more than 48 hours. Just across the Bosphorus in Kadikoy, long favoured by young professionals, new listings are bombarded by inquiries within hours on platforms like Sahibinden.com. "There was a flat in Moda at 28,000 TL—it had forty applications within a day," a local property manager told The Daily Istanbul. Meanwhile, newer buildings in Bomonti, Sisli, are now fetching upwards of 52,000 TL per month for a 3+1, after years as a mid-range option.

Developers and landlords blame a trio of forces: surging demand from foreigners obtaining Turkish citizenship through investment, a trickle of returning expatriates, and an inadequate supply of new builds in districts with strong amenities. Government data published by the Istanbul Chamber of Commerce shows that the number of new properties registered in the city centre fell 13% year-on-year in 2025. Many owners now favour selling or short-term Airbnb-style lets, further shrinking conventional rental stock.

Numbers That Tell the Story

The concrete numbers show the scale of the problem. According to Endeksa, Istanbul’s average rent surpassed 25,400 TL per month in June 2026—a 44% increase from the same month last year and nearly double pre-pandemic rates. Central neighbourhoods like Cihangir and Etiler have topped 60,000 TL for family-size apartments, while even marginal districts such as Esenyurt, traditionally a budget-friendly option, have seen rents jump 20% in 12 months, up to an average of 13,500 TL. Several property portals report that single-bedroom listings in Nisantasi or Karakoy can attract over 100 phone calls within the first day.

The lack of supply is widest at affordable price points. A survey by the Istanbul Metropolitan Municipality in May found vacancy rates below 1.7% for apartments under 20,000 TL per month, with prospective tenants now organizing documents and proof of funds before even viewing properties.

What Next for Istanbul’s Renters—and Buyers?

Some experts forecast that pressure will persist until at least the end of 2027, when a raft of residential projects in Atasehir and Maltepe are due for completion. For now, tenants are advised to enlist licensed agents, move quickly with offers, and expect to pay several months’ rent upfront as security. For those frustrated by the rental squeeze, homebuying remains even less attainable for many: the citywide average price per square metre topped USD $2,500 in June, placing a typical 100 sqm flat well over USD $250,000—far beyond the borrowing capacity of most local families.

Unless more affordable housing comes onstream or migration trends shift, Istanbul’s rental market looks set for continued intensity, especially in prime areas near job centers or transit lines. For now, securing a flat has become a competitive sport—one played out every week in stairwells and WhatsApp groups across this restless city.
