Kâğıthane Is the Name Every Istanbul Property Investor Is Saying Right Now

The Istanbul Metropolitan Municipality approved 14 new mixed-use development permits in Kâğıthane district during the first half of 2026, more than any other single district outside the historic peninsula. That number, confirmed in municipal planning records published last month, has crystallised what property agents and developers have been quietly tracking for the better part of two years: Kâğıthane has crossed from speculation into active transformation.

The timing matters. Istanbul's established premium neighbourhoods — Beşiktaş, Beyoğlu, Nişantaşı — are now averaging north of $4,500 per square metre for new-build residential stock, pricing out a segment of internationally mobile buyers who still want European-side convenience. Kâğıthane, sitting directly south of those districts and connected to them by the M7 metro line that extended through Bomonti and Çağlayan in late 2024, is offering comparable transit access at a citywide average closer to $2,200 per square metre. The gap is doing the selling.

What Is Actually Getting Built

The biggest single project currently under construction is the Kâğıthane Merkez mixed-use tower cluster on Ortabayır Mahallesi, a 340-unit residential and retail development by Istanbul-based Kalyon İnşaat that broke ground in March 2025 and is targeting a Q4 2027 handover. A second scheme, the Hasebe Residence on Çağlayan Caddesi by developer Özgün Yapı, delivered its first 80 units in May and sold out within six weeks at prices between $2,050 and $2,450 per square metre — figures that agents say would have been unthinkable in the district four years ago.

The district's industrial legacy is actually part of the pitch. Kâğıthane spent decades as a manufacturing zone, which means unusually large land parcels are still available for consolidation and redevelopment — a scarcity in a city where central plots are subdivided to the point of impracticality. The Levent-Mahmutbey highway corridor runs along the district's western edge, giving residents direct road access to both the third bridge ring road and the E-80 motorway toward the airport. For buyers qualifying under Turkey's citizenship-by-investment programme, which requires a minimum $400,000 property purchase, that infrastructure profile is a genuine selling point rather than an afterthought.

Foreign Buyers and the Citizenship Calculation

Turkey's Tapu ve Kadastro Genel Müdürlüğü — the General Directorate of Land Registry and Cadastre — reported that foreign nationals completed 4,812 property purchases in Istanbul in the first quarter of 2026, with Gulf state and Central Asian buyers collectively accounting for roughly 38 percent of that volume. Kâğıthane ranked fifth among Istanbul districts by foreign transaction count in Q1, up from outside the top ten in the same period two years ago.

Real estate consultancy RE/MAX Turkey flagged Kâğıthane in its June 2026 market report as one of three Istanbul districts with the strongest price growth trajectory over the next 24 months, alongside Başakşehir and Ataşehir on the Asian side. Average asking prices in the district have risen approximately 18 percent in dollar terms since January 2025, outpacing the 11 percent citywide average for the same period.

Buyers considering the district should move through due diligence carefully. Several parcels along the old factory belt near Seyrantepe still carry remediation obligations under the municipality's 2023 brownfield redevelopment framework, and those costs can materially affect project timelines. The Kâğıthane Belediyesi planning department publishes parcel-level status reports through its İmar Durumu portal, and cross-referencing any off-plan purchase against that database before signing a sales agreement is basic prudence. Projects that have cleared remediation and hold full ruhsat — construction permits — from both the district and metropolitan levels are in a meaningfully different risk category from those that haven't. The permits approved in the first half of 2026 suggest the pipeline is moving. The prices suggest the window before a Şişli-style premium correction is not indefinitely open.
