Kkangtong Jeonse: Korea's "Empty Can" Deposit Trap

When people rent on jeonse, they trust that they'll get 100% of their deposit back when they move out. But once the landlord's debt plus your deposit goes above 80% of the home's price, a warning light turns on.

Here's an example. Say a small apartment building unit (a "villa") is worth 200 million won. The landlord has a 100 million won bank loan, and your jeonse deposit is 120 million won. Together, that's 220 million won in debt. The debt is bigger than the home's value. If the unit sells on the market, it brings in only 200 million won. Unless the landlord adds their own money, they can't return your full deposit.

In the end, the landlord owns nothing real, and the whole house is filled with other people's money. It looks fine outside but is hollow inside, which is why it's called an empty can of a house.

The main causes are falling home prices and reckless gap investing (buying a home that already has a jeonse tenant, using the tenant's deposit to cover most of the price). Some landlords believed prices would keep rising. They put in almost none of their own money and bought dozens of homes using only tenants' deposits.

Then the property market cools and prices fall, and the trouble begins. When the landlord looks for a new tenant, the going jeonse rate is lower, so there isn't enough money to pay back the old tenant. If the landlord can't come up with the cash, the bank may file for a court auction. Or the tenant has to sue first and then file for the auction themselves.

Here's the catch. Auctioned homes usually sell for much less than market price. On top of that, bank loans (mortgages) set up before the tenant secured legal protection, and some of the landlord's unpaid taxes, get paid first. Protection here means the tenant moved in and registered their address, and had the lease date officially stamped. Because of this, the tenant can suffer the loss of a large part of the deposit.

To avoid a kkangtong jeonse, check carefully before you sign. First, get the property's registry record, which works like the house's ID card. It shows how much bank debt (mortgage) is attached to the home.

Second, look at the jeonse ratio, which is your deposit divided by the home's price. As a rule of thumb, it's considered relatively safe at 70% or less of the sale price for apartments. For villas, where prices are harder to pin down, 60% or less is the safer mark.

Third, and most reliable, is to buy deposit return guarantee insurance. There are conditions, though. For example, the deposit plus the landlord's debt must stay within a certain share of the home's price, so riskier homes may be turned down. But if you do get covered and the landlord can't pay you back, a guarantee agency (such as HUG or SGI in Korea) pays your deposit back first. Then the agency collects the money from the landlord.
