Jeonse (전세) is a Korean housing arrangement in which a tenant pays the landlord a large refundable deposit and, under a pure jeonse contract, no monthly rent. The landlord must return the deposit when the lease ends. Utilities, building management charges, parking fees, and similar expenses are handled separately according to the contract.
The deposit is not a conventional security deposit. It can amount to hundreds of millions of won and may come from the tenant’s savings, a jeonse loan, or both. Understanding how jeonse works in South Korea therefore means examining not only the rent terms, but also whether the landlord and property can support repayment.
Jeonse in a simple example
Suppose an apartment is worth approximately ₩500 million and is offered with a ₩300 million jeonse deposit:
- The tenant signs a lease, pays the agreed contract payment, and pays the remaining deposit on the balance-payment or move-in date.
- The tenant occupies the apartment for the lease period, commonly two years.
- The tenant pays the expenses assigned under the contract but no monthly rent.
- At the end of the lease, the landlord returns ₩300 million as the tenant hands back possession.
The home is not economically free. A tenant using savings gives up the return that money might have earned elsewhere, while a tenant using a loan pays interest. The landlord receives temporary use of the deposit and may use it to reduce debt, finance another property, or make other investments.
Some landlords expect to repay an outgoing tenant with the deposit from a replacement tenant. That becomes difficult if market deposits fall or a new tenant cannot be found. If the next tenant will pay only ₩240 million, a landlord who owes ₩300 million must produce the ₩60 million difference elsewhere.
Jeonse, wolse, and mixed leases
- Jeonse (전세): A large refundable deposit with no regular monthly rent.
- Wolse (월세): Monthly rent accompanied by a smaller refundable deposit.
- Ban-jeonse (반전세): An informal label for a mixed arrangement with a substantial deposit and monthly rent.
Listing labels are not always precise, so rely on the written numbers. For example, 보증금 1억 / 월세 80 means a ₩100 million deposit and ₩800,000 per month. It is not pure jeonse.
The jeonse price ratio, or 전세가율, compares the deposit with the home’s sale value. A higher ratio generally leaves less equity available to absorb a fall in the property’s value.
What to check before signing
Confirm the owner and registered claims
Obtain a recent real-estate registry certificate, formally called a 등기사항증명서 and still commonly called a 등기부등본. Check that the person signing as landlord is the registered owner and review mortgages, seizures, provisional registrations, and trust registrations.
If a representative signs, verify the owner’s identification, power of attorney, and seal documentation. A property registered in trust requires particular care because the person presented as the landlord may need authority or consent from the trustee.
Examine debts that may rank ahead of the tenant
Do not compare the deposit only with an asking price. Use recent, realistic sale information and calculate mortgages and other senior claims. In a dagagu (다가구) building, one owner holds the building containing several rental units, so deposits belonging to earlier tenants can also reduce the money available for repayment.
At contract signing, the landlord must present information about existing confirmed-date leases and national and local tax payment certificates, or consent to the relevant inquiries. These records matter because senior tenant deposits and certain tax claims may affect recovery. source
Write protective terms into the contract
A contract payment of about 10% is common practice, but it is not a universal statutory amount. The agreement should identify the exact unit, total deposit, payment dates, lease period, repair responsibilities, management charges, and conditions for returning the deposit.
Consider a special clause preventing the landlord from creating new mortgages or other senior rights before the tenant completes the steps needed for legal protection. Another clause can require cooperation with a deposit-return guarantee and permit cancellation if the property proves ineligible. For a large deposit or an unusual ownership structure, obtain professional advice on the wording.
Legal steps after signing
Recheck the registry before paying the balance
Rights can change between contract signing and move-in. Obtain another registry certificate immediately before transferring the remaining deposit. Confirm that no unexpected mortgage, ownership transfer, seizure, or trust-related entry has appeared.
Take possession and register the address
Under the Housing Lease Protection Act, a tenant who takes possession and completes resident registration gains enforceability against third parties from the following day. A move-in report, 전입신고, is treated as completing resident registration for this purpose. source
Registered foreign residents should complete the corresponding foreign registration or change-of-place-of-stay procedure and ensure that the recorded address, including the unit where required, is accurate. Korean Supreme Court precedent recognizes qualifying foreign registration and place-of-stay reporting as equivalent to resident registration for housing-lease protection. source
Obtain a confirmed date
A confirmed date, or 확정일자, helps establish preferential repayment rights if the property enters foreclosure or public auction. In practical terms, a residential tenant normally wants all three elements: possession, the appropriate address registration, and a confirmed date. source
Covered housing leases must be reported within 30 days when the deposit exceeds ₩60 million or the monthly rent exceeds ₩300,000. The reporting system applies in the Seoul metropolitan area, metropolitan cities, Sejong, Jeju, and city areas of the provinces. If the lease document is submitted with the report, the confirmed date is treated as granted when the report is accepted. source
Lease length, renewal, and increases
Residential jeonse agreements are commonly written for two years. A lease with no stated period or a term shorter than two years is generally treated as lasting two years for the tenant’s protection, although the tenant may choose to rely on the shorter agreed term. source
A tenant may generally exercise the statutory renewal-request right once, adding two years. The request must be made during the legally defined period beginning six months before expiration and ending two months before expiration. A landlord may refuse only for a statutory reason, such as qualifying rent arrears, unauthorized subletting, serious misconduct or damage, or genuine residence by the landlord or the landlord’s lineal ascendant or descendant. source
An increase claim is generally limited to 5% of the existing rent or deposit and cannot be made within one year of the lease or the previous increase. Local governments may set a lower ceiling. This rule does not mean that every completely new lease negotiated after the protected relationship ends must remain within 5% of the former deposit. source
Why the deposit may be at risk
The central risk is that the landlord may be unable to return the money. Address registration and a confirmed date improve the tenant’s legal priority, but they cannot guarantee full recovery if the property’s sale proceeds are insufficient.
Consider a property with these figures:
- Realistic sale value: ₩300 million
- Existing senior mortgage: ₩100 million
- Proposed jeonse deposit: ₩220 million
The mortgage and deposit total ₩320 million before auction expenses or a possible discounted sale. This is the type of situation associated with kkangtong jeonse (깡통전세), a property with little or no equity supporting the tenant’s deposit.
A licensed real-estate agent can help gather and explain documents, but broker involvement does not make the transaction risk-free. Tenants should independently confirm the registry, property value, landlord identity, tax information, senior deposits, and guarantee eligibility.
Deposit-return guarantees
A jeonse deposit-return guarantee can pay an eligible tenant when the landlord fails to return the deposit, after which the guarantor pursues the landlord. Providers include the Korea Housing and Urban Guarantee Corporation, or HUG, and the Korea Housing Finance Corporation, or HF. HF’s standard product is generally connected to tenants using or applying for an HF-backed jeonse loan guarantee. source
As of September 14, 2026, HUG’s product is officially named 전세보증금반환보증. Its published deposit ceiling is ₩700 million in the Seoul metropolitan area and ₩500 million elsewhere, and ordinary applications generally must be made before half of the lease period has passed. HF also requires application before the halfway point and calculates eligibility using the property value and senior claims. source
A guarantee is not automatic. Eligibility depends on the property type and valuation, deposit amount, senior debt, lease terms, address registration, application timing, and provider-specific screening. Check likely eligibility before signing rather than assuming the contract can be insured later.
A practical jeonse checklist
- Compare the deposit with recent, realistic sale prices.
- Check the registry before signing and again before paying the balance.
- Verify the owner, any representative, and the authority to lease a trust-owned property.
- Calculate mortgages, earlier tenant deposits, and other senior claims.
- Review the landlord’s required lease and tax information.
- Confirm deposit-return guarantee eligibility before committing.
- Use clear clauses covering new mortgages, guarantee cooperation, repairs, and repayment.
- Take possession, register the address, and obtain a confirmed date promptly.
- Keep the lease, registry copies, transfer receipts, messages, and inspection records.
When the lease ends
A tenant who does not intend to renew should notify the landlord at least two months before expiration and preserve evidence that the notice was received. Without timely notice, the lease may renew tacitly for two years. After a tacit renewal, the tenant may give notice at any time, but termination takes effect three months after the landlord receives it. source
Deposit repayment and the return of possession are normally handled together. Do not casually move out and transfer the registered address before receiving the deposit, because continued possession and address registration ordinarily help preserve the tenant’s protections. source
If the lease has ended and the deposit remains unpaid, a tenant who must leave can apply to the court for a tenant-right registration order, or 임차권등기명령. Moving should generally wait until the resulting registration has been completed, not merely applied for. Because timing mistakes can affect a large claim, assistance from a housing counselor, judicial scrivener, guarantee provider, or lawyer may be worthwhile. source
Jeonse can suit a tenant who has substantial capital or affordable financing and wants to minimize monthly payments. The decisive question, however, is not simply whether the deposit can be raised. It is whether the property value, senior claims, ownership structure, legal priority, and guarantee coverage make placing that amount of money with this particular landlord a defensible risk.
