Jeonse vs. Monthly Rent in Korea — Case-by-Case Analysis (2026)

The framework — opportunity cost + risk

Comparing jeonse and monthly rent is never about face value alone. Always model these four:

1. Opportunity cost of the deposit (deposit rate / investment yield)
2. Interest cost of the jeonse loan
3. Monthly-rent tax credit (17% if salary ≤ ₩70M)
4. Risk premium of deposit non-return

2026 market inputs

• Jeonse loan rate: 4.8–5.2% (HUG-guaranteed)
• Conversion ratio: 5.5% Seoul average (Korea Real Estate Board)
• Monthly-rent credit: ₩7.5M cap, 17% (salary ≤ ₩55M)
• Deposit rate: 3.0–3.5%

Case 1 — ₩150M deposit / 4 years / single under 30 (salary ₩45M)

• Jeonse: ₩150M × 5% = ₩7.5M/yr interest
• Monthly: ₩10M deposit + ₩700K/mo = ₩8.4M → ₩6.96M after credit
• Verdict: monthly rent wins by ~₩540K/yr, plus zero deposit risk

Case 2 — ₩400M deposit / 6 years / dual income (₩120M)

• Jeonse: ₩400M × 5% = ₩20M/yr interest
• Monthly: ₩100M deposit + ₩1.8M/mo = ₩21.6M (no tax credit)
• Verdict: jeonse wins by ~₩1.6M/yr, but factor in deposit-recovery risk

Case 3 — ₩600M deposit / new Gangnam officetel

• New-builds are the #1 underwater-jeonse risk → half-jeonse preferred
• Typical balance: ₩200M deposit + ₩2.5M/mo

Case 4 — ₩80M deposit / regional / 1-year stay

• One-year stays can't recoup brokerage + moving + filing costs
• Always pick monthly rent

Decision checklist

• [ ] Deposit locks > 60% of net worth? → Consider monthly rent
• [ ] Underwater-jeonse score ≥ 70? → Walk away or monthly only
• [ ] Salary ≤ ₩70M and rent ≥ ₩500K? → Use monthly tax credit
• [ ] Stay ≤ 3 years? → Monthly (jeonse fixed costs don't amortize)
