Istanbul vs. Seoul: Detailed 2026 Cost of Living & Quality Comparison

Introduction

Istanbul and Seoul create a practical long-term living comparison rather than a simple travel-style choice. Istanbul has a clearer case for overall affordability, rent and housing, and climate comfort. Seoul has a clearer case for transport costs, pollution-related indicators, commute-related indicators, income and purchasing power, quality of life, and safety. The comparison stays within measurable living indicators and avoids unsupported claims about neighborhoods, infrastructure, services, or local routines.
