Frequently Asked Questions
What is jeonse and how does it differ from monthly rent?
Jeonse (전세) is a unique Korean rental system where the tenant pays a large lump-sum deposit (typically 50–80% of the property value) instead of monthly rent. The landlord invests or earns interest on the deposit, returning the full amount at lease end.
How is the jeonse-to-monthly-rent conversion rate calculated?
The conversion rate (전월세 전환율) converts between jeonse deposit and monthly rent. Monthly rent = (Jeonse deposit – Actual deposit) × Conversion rate / 12. The government publishes a reference rate (typically 2–4%), though actual rates vary by location and market conditions.
Is jeonse still popular in Korea?
Jeonse has become less common due to low interest rates reducing landlord returns, and several high-profile jeonse fraud cases. The trend has shifted toward wolse (monthly rent with a smaller deposit) or half-jeonse arrangements combining a moderate deposit with reduced monthly rent.
