Istanbul’s 2026 Property Market: How Today’s Cycle Stacks Against the 2021 Boom

Five years after Istanbul’s headline-making real estate boom, property prices in the city are advancing, but the breakneck pace of 2021 is a memory. The current market, analysts say, is more selective—and arguably more sustainable—with average resale values hovering near $2,500 per square metre, up around 43% from mid-2021, but up just 4% over the past 12 months.

The context has shifted in several key ways. Back in 2021, pent-up pandemic demand and unchecked foreign capital—turbocharged by the citizenship-for-investment scheme—sent buyers racing for flats from Levent to Kadıköy. But the stakes feel different this summer, as economic uncertainty across Europe, the threat of more extreme weather, and regional conflict pressure both local and foreign investors to reassess their moves.

Selective Gains by District

Beyoğlu still fetches a premium, especially in projects around Tomtom Street and the renovated French Passage, but price-growth is flattening. According to Istanbul Chamber of Real Estate Agencies (İSTEB), transaction volumes in central Şişli are up 7% since January, due in part to a cluster of new residential towers around the Bomonti area. On the Asian side, investors once turbocharged by visas are eyeing larger family units in Kadıköy—particularly near Moda and Bahariye—where green space, transport access and less congested streets have driven a fresh round of interest, even as prices have edged up just 2% since last summer.

Down the Bosphorus, Ortaköy and Beşiktaş continue to claim the highest price tags, with waterfront penthouses on streets like Kuruçeşme Caddesi seeing little discounting. Yet high transaction costs and the lira’s continued wobble have cooled the frenzy. "In 2021, homes would sell within 48 hours; now sellers wait weeks, sometimes months," an agent with Eskidji Gayrimenkul on Akaretler Avenue told The Daily Istanbul.

Numbers Tell a Quieter Story

Citywide, the Istanbul Real Estate Platform reports an average sale price of $2,500 per square metre for the city as of June 2026. In 2021, prices soared nearly 30% in a single year, peaking by late summer. This year, however, overall transaction volume is down 11% year-on-year. Beşiktaş listings are stagnant at $6,750/sqm on average, while Şişli has grown to $3,300/sqm following last winter’s new project launches. Foreign buyers—still accounting for about 19% of all sales—are shifting attention from luxury towers to mid-market units, responding to changes in both Turkey’s residency policies and steeper global financing costs.

Several big projects are set for completion before year’s end, including the Galataport Residences, which already command prices north of $8,500/sqm but have seen fewer than 35% of units sell to foreign passport investors compared to more than 60% during the 2021 run. According to data from Tapu ve Kadastro Genel Müdürlüğü, completed transactions involving foreign nationals actually fell 21% from Q2 of 2021 to Q2 of this year—further evidence that the speculative fever has died down, at least for now.

What’s Next for Buyers and Sellers?

Experienced agents across Istanbul’s most popular neighbourhoods are advising buyers to move deliberately, with most believing steady—if unspectacular—price growth will continue unless a shock event rattles the lira or investor confidence. Buyers continue to favour new units in well-located projects, and some families are holding off on upgrades given rising interest rates from local banks like İşbank and Yapı Kredi. For international buyers weighing Turkey’s citizenship-for-investment scheme, minimum thresholds remain at $400,000 per property—unchanged since the last hike in 2022—but the buzz has clearly faded from the fevered days of 2021.

The bottom line for Istanbul: this is not a repeat of the runaway boom that rewrote the city’s property script five years ago. But as regional volatility keeps global investors watchful, those betting on a long-term play in Istanbul’s better-located districts may find today’s more measured climate a rare window—if they have the patience to wait out the headlines.
