Jeonse Explained for Foreigners (2026): How Korea's Deposit-Only Lease Works, Jeonse vs Wolse Cost Calculator, Deposit Protection (HUG), and the 5 Checks Before You Sign

Jeonse (전세) is the Korean lease that confuses every newcomer: you hand the landlord a deposit equal to 50–80% of what the home is worth, live there for two years paying no rent, and get the whole deposit back when you leave. The landlord's income is what they earn by investing your money; your cost is the interest you forgo. It exists nowhere else at this scale, it is the reason Korean households hold so much of their wealth in deposits, and — because a deposit of several hundred million won sits with a private individual for two years — it carries a risk that wolse (monthly rent) does not. This part explains the economics, gives you a jeonse-vs-wolse calculator, and lists the checks that keep a foreign tenant's deposit safe.

How the numbers work

A Seoul apartment that would sell for ₩1.0 billion typically rents on jeonse for ₩600–700 million — the jeonse ratio is 68.9% nationally, 62.8% in the capital region and 74.7% in the provinces, as of May 2026. The average Seoul apartment jeonse is about 약 7억 1,000만 원 (KB 2026-08). The landlord either invests the deposit or, more often, has used it to finance buying the apartment in the first place (the "gap investment" that makes jeonse a form of interest-free leverage for owners).

For the tenant, the cost is the return the deposit would have earned. With one-year bank deposits at about 3.4%, a ₩600M jeonse costs roughly ₩1.7M a month in forgone interest — usually less than the equivalent wolse, which is why Koreans with the cash (or a cheap jeonse loan) prefer it. Wolse (월세) is the alternative: a smaller deposit (₩10–100M) plus monthly rent; semi-jeonse (반전세) is anything in between. The law fixes the exchange rate between them: when a landlord converts deposit into rent during a lease, the rent may not exceed 5% a year of the converted amount (3% base rate + 2 points).

Leases run two years, with a right to renew once for two more at no more than a 5% increase — a landlord can refuse only to move in themselves or for a few other listed reasons. For a foreigner on a three-year contract, that is four years of housing at a predictable cost.

Protecting the deposit as a foreigner

A jeonse deposit is an unsecured loan to your landlord. Three steps make it a secured one under the Housing Lease Protection Act, and every one of them is available to a foreign tenant:

1. Move in and take possession.
2. Register the address. Koreans do a 전입신고; foreigners file a change of place of stay (체류지 변경 신고) at the immigration office (or the district office, which forwards it) within 15 days. Article 88-2 of the Immigration Act deems this equivalent to a Korean's resident registration, giving you opposability (대항력) — a new owner or a bank cannot evict you without repaying the deposit.
3. Fixed-date stamp (확정일자) on the contract at the district office (₩600) or online through the Internet Registry Office. This gives your deposit priority over later mortgages.

Do all three on moving day; priority runs from the day after registration. Then insure the deposit with the Korea Housing & Urban Guarantee Corporation (HUG, 전세보증금 반환보증) or SGI: HUG covers deposits up to ₩700,000,000 in the capital region (₩500,000,000 elsewhere) where the deposit is within 90% of the home's value including prior mortgages, at a premium of about 0.115% a year for apartments. Foreigners with an ARC can apply, within the first half of the lease. If the landlord does not return the deposit, HUG pays you and pursues them.

The five checks before signing

1. Title register (등기부등본, ₩700 at iros.go.kr): the owner named must be the person you contract with and receive the deposit; any mortgage (근저당) plus your deposit should be under 70–80% of the market price; look for seizure or provisional registration entries.
2. Market price on KB, the Korea Real Estate Board or recent transactions (실거래가): a deposit above 80% of value is the classic fraud pattern, common with villas (multi-unit low-rise) where prices are opaque.
3. Landlord's tax arrears: for deposits over ₩10,000,000 you may check the landlord's unpaid national and local taxes before contract (unpaid taxes outrank your deposit in a forced sale).
4. Other tenants' deposits in a multi-unit building (확정일자 부여현황 from the district office) — the total ahead of you matters.
5. Contract terms through a licensed broker (공인중개사), with the broker's insurance certificate; the deposit is transferred to the owner's own account, never a "manager's".

Standard contracts are in Korean; an English-Korean bilingual version is available from Seoul Global Center, and the Korean text governs.

Jeonse loans and the foreigner gap

The cheapest way Koreans finance jeonse — government-backed loans at 2–4% — is largely closed to foreigners. Commercial banks lend against jeonse contracts to some F-2/F-5/F-6 holders and to E-7 employees of large companies at about 4–5%, but policies vary by bank and branch and often require a Korean guarantor. The practical options are a semi-jeonse negotiated with the landlord, or a wolse with a deposit you can afford. Company housing loans (from some large employers) are the other route.

If you do hold a large deposit, the question becomes what to do with the rest of your savings while it sits there. The next part covers the two tax-advantaged accounts open to foreign residents — the ISA and the IRP — and the flat-tax catch.
