How jeonse made it possible
Under jeonse, unique to Korea, a tenant pays no monthly rent but lends the landlord a deposit often worth most of the home's price, returned at lease end (Ambrose & Kim, 2003). It works while prices rise, but the deposit is effectively an unsecured loan. As the market shifted (Ronald & Jin, 2015), the early 2020s brought 'villa king' cases, owners who bought hundreds of units with tenants' money, and mass losses in Incheon. Korea enacted a special support act effective 1 June 2023.
Common tactics
- 'Empty-can' jeonse: the deposit is near or above the sale price.
- No-capital gap investing funded by deposits.
- Hidden senior claims such as mortgages or tax arrears.
- Exploiting the one-day gap: move-in registration takes effect at midnight the next day, so a mortgage registered the same day ranks first.
Support and economics
Victims are generally those with legal priority via move-in registration, deposits up to 500 million won, multiple victims, and signs of no intent to repay. Support includes auction deferral, priority purchase rights, public purchase of homes by LH, low-rate loans and legal help; 34,481 cases had been decided by October 2025 (Ministry of Land, Infrastructure and Transport, 2025). Economically it is an information asymmetry problem like Akerlof's (1970) lemons, and Becker's (1968) deterrence logic drives calls for tougher fraud sentencing.
Checklist
- Check the property register for mortgages and trusts.
- Ask for proof of paid taxes and senior deposits.
- Avoid deposits close to the sale price.
- Confirm eligibility for a deposit return guarantee.
- Register your move-in and get a fixed date on day one; see the Housing Lease Protection Act.
FAQ
- How do I spot an 'empty-can' lease?
- Add senior mortgages and deposits; if the total nears the sale price, walk away.
- What if my deposit isn't returned?
- Seek a lease-registration order, claim on any guarantee, and contact the victim support center.
