Istanbul Property Market Split: House vs Unit Prices Part Ways as Demand Shifts

Detached house prices across Istanbul have surged nearly 11% over the past twelve months, outpacing the city’s apartment units, whose average rates grew just 5.2% in the same period, according to data released this week by TSKB Real Estate Appraisal. The widening gulf between house and unit values is reshaping local neighbourhoods and forcing buyers to reconsider their next move, particularly in districts like Bebek and Moda that are seeing intense competition for spacious standalones.

Why the Divergence Appeared This Year

The split in price performance has created a fresh dilemma for both property owners and prospective buyers. Several factors are in play, including shifting household preferences since the pandemic, the impact of foreign investment programs, and the return of Turkish expatriates amid regional instability. The average price for a freestanding house in Suadiye has now reached USD 3,700 per square metre, with limited new supply pushing up valuations even faster since late 2025. Meanwhile, despite continued demand for downtown living, many of the city’s apartment projects in Kagithane and Esenyurt are reporting only modest capital gains, with oversupply in those corridors placing a ceiling on price growth.

The divergence isn’t just a tale of neighbourhood status. Brokers in Besiktas and Beyoglu note buyers are favouring historic detached homes on streets like Palanga Caddesi, even as luxury unit towers in the same zip code see slower sales. Zingat’s June sales tracker reported a record 13.4% jump in detached villa transactions in the Asian-side enclaves of Acarkent and Çengelköy compared with June 2025. By contrast, new-build apartment turnover in Şişli and Bomonti is only just clearing last year’s levels.

Numbers Tell the Story

Across Istanbul, the citywide average price for residential property sits around USD 2,500 per square metre. That figure, though, masks widening disparities: detached houses have blown past the average, while units — especially older stock — are increasingly slow to sell. Data from the Land Registry show that in May 2026, just 45% of listed apartments in Fatih met their asking price, down from 62% in September 2025. Meanwhile, houses on narrow lanes near Yıldız Park routinely attract multiple offers from both local and Gulf investors. Demand for homes eligible for citizenship-by-investment remains stubbornly high, particularly around waterfront precincts in Arnavutköy and Kanlıca, where average prices pushed above USD 5,000 per square metre last quarter.

Consultants at Eva Gayrimenkul suggest several consequences from the ongoing rift. First, first-time buyers may be priced out of the house market but find bargains in surplus unit developments. Second, sellers of older apartments — especially in large blocks without amenities — are being forced to rethink their expectations. Third, the chronic lack of land in well-connected districts like Nişantaşı is ensuring houses will likely hold their premium for the foreseeable future.

Looking Ahead: What Buyers Should Watch

The consensus among Istanbul realtors is clear: anyone holding a freestanding house in the inner city has seen a windfall, and little let-up is expected as long as supply stays tight. Apartment hunters, meanwhile, are advised to scrutinize site maintenance charges and check proximity to new metro extensions, as positional advantages have become even more vital to value retention. The next six months may bring further volatility if foreign investor appetite fluctuates or new economic measures emerge post-election. For now, experts suggest buyers work with registered agencies, consult up-to-date appraisals, and consider waiting for the autumn lull when negotiations may tilt in their favour.
