Galataport opened in 2021 with a mixed-use cruise terminal, hotels, retail and residential running along the Karaköy waterfront. The adjacent streets — Kemeraltı, Kılıç Ali Paşa — re-rated 40-60% in USD terms over 2021-2024 before cooling into 2026. Beyoğlu generally followed.
Istanbul Finance Center (Ataşehir / Ümraniye) officially opened in 2023 and is slowly populating — CBRT moved headquarters, major banks followed. The Asian-side financial belt has been the strongest USD-price performer in the city since, with rental demand for corporate housing keeping gross yields around 5.2% despite price growth.
Kanal Istanbul sits in a different category — still officially planned but perpetually delayed. Don't underwrite the corridor unless you're prepared to hold for 10+ years with no discount rate on political timing.
The pattern across all three: infrastructure catalyst → nearby rental demand tightens → prices catch up to rents, not the other way around. Buy in the catchment before rents move; don't chase prices once they've run.
