Analyze debt ratios to identify "Underwater Jeonse" risks.
What is a Jeonse Safety Diagnostic?
A Jeonse Safety Diagnostic is the process of evaluating the debt risk of a property to protect your deposit from "Underwater Jeonse" (깡통전세). It analyzes the Debt-to-Value Ratio by combining the property's market price with its existing mortgages and your proposed deposit. In 2026, understanding updated HUG Deposit Insurance standards (like the 126% rule) is critical for expats and locals alike to avoid rental fraud in South Korea.

FAQ
Quick answers to common questions.
What is 'Underwater Jeonse' (깡통전세)?
Underwater Jeonse occurs when the total debt on a property (mortgages + deposits) exceeds its market value. If the landlord defaults, tenants may lose their deposit.
What is a safe Jeonse debt ratio?
A debt ratio below 70% is generally considered safe. 70-80% requires caution and HUG insurance. Above 80% is high risk.
What is HUG deposit insurance?
HUG (Korea Housing and Urban Guarantee Corporation) provides Jeonse deposit return insurance that protects tenants if landlords fail to return deposits.
How do I check a property's mortgage?
Request a 'Certified Copy of Registry' (등기부등본) and check 'Section Eul' (을구) for any liens or mortgages registered against the property.
