Korean Jeonse Fraud Prevention in 7 Steps (2026 Edition)

Why Korean jeonse fraud isn't going away

Jeonse-deposit incidents totaled ₩4.4T in 2024 and ₩3T+ in 2025. Hot zones — per HUG data — remain concentrated in new-build multi-unit and officetel buildings in metro Seoul (Michuhol-gu, Gangseo-gu, Bucheon, Hwaseong). Because the root cause is structural information asymmetry, a 30-minute pre-contract self-check is the single most effective defense.

Step 1 — Pull the property registry (₩1,000)

Use Korea’s e-registry portal (iros.go.kr) to pull the full title / Section A (ownership) / Section B (encumbrances) of the property.

• Sum the maximum-mortgage amounts in Section B and divide by market price → debt ratio.
• Debt ratio ≥ 70% means the property is at high "underwater jeonse" risk.

Step 2 — Verify market price across 3 sources

• MOLIT real-transaction database (rt.molit.go.kr)
• Korean real-estate platforms (Zigbang, Dabang, Naver Real Estate)
• 3+ comparable transactions in the same complex

For new villas with thin transaction history, do NOT rely on HUG official-price × 126% alone. Triangulate with nearby comparable trades.

Step 3 — Verify the landlord's identity

• Match Section-A owner to the landlord’s national ID.
• If the landlord is a corporation, also pull the corporate registry.
• Ask for the business-registration certificate and income-tax payment proof — fraudulent landlords reject this 99% of the time.

Step 4 — Compute jeonse risk score

Use the Jeonse Risk Score tool to combine deposit, senior debt, and market price into an automated score. Anything above 70 should trigger a renegotiation or walk-away decision.

Step 5 — Check HUG / SGI insurance eligibility

Jeonse Deposit Insurance Eligibility Checker tells you whether HUG / SGI / HF will insure the deposit. A "rejected" verdict is itself a red flag.

Step 6 — 5 must-have contract clauses

1. Deposit returned immediately upon landlord change
2. No additional mortgages may be filed
3. Confirmed-date and resident-registration take priority
4. Contract is void if HUG insurance cannot be obtained
5. Deposit returned within 30 days of termination notice

Step 7 — 30-day post-move-in checklist

• Resident registration (day of move-in)
• Confirmed date (district office, with the contract)
• File HUG or SGI insurance (within 1 month)
• File the lease with the local government

Bottom line

Jeonse fraud isn’t about luck — it’s about preparation.
