Turkey Housing Supply Crisis: Why Rents Keep Rising

Istanbul's rental market has been in structural undersupply for several years, and the gap between supply and demand shows no sign of closing quickly. Understanding why matters for both tenants and investors.

Population Growth

Istanbul's population grows by approximately 300,000–400,000 people per year through internal migration from other Turkish cities. This sustained inflow creates consistent demand for rental housing that construction has struggled to match.

Construction Slowdown

The combination of rising construction costs (materials inflation of 80–120% in 2022–2023), financing difficulties for developers, and increased earthquake safety requirements following the 2023 Kahramanmaraş earthquake has significantly slowed new construction completions.

Planning Constraints

Large parts of Istanbul are now subject to urban transformation zones (kentsel dönüşüm) where older buildings must be demolished and rebuilt to new earthquake standards. This process reduces the available housing stock temporarily and adds to supply pressure.

When Will Relief Come?

The pipeline of permitted but incomplete projects suggests supply will increase in 2025–2026. But until then, rental price pressure is likely to continue in Istanbul's most popular districts.
