The first time you rent a one-room in Korea, the number that stops you isn’t the rent. It’s the deposit — often several million won, sometimes ten million or more, paid before you’ve slept a night in the place. For many international students it’s the largest single payment of their first year after tuition.
That deposit is supposed to come back. This guide explains how the system works, what you pay and when, what to check before you hand over money, and how to protect your deposit and seek its return when you leave. If you’re still deciding what kind of housing to choose, start with Dormitory vs Goshiwon vs One-Room vs Share House; this post picks up once a deposit is involved.
The short answer
- Most students who rent a one-room off campus do so on 월세: a refundable deposit (보증금) plus monthly rent. A bigger deposit usually means lower rent.
- Expect several payments around signing: a contract payment (part of the deposit), the balance on move-in, the first month’s rent, and an agent’s fee.
- Before paying anything, check who owns the property, what debts are registered against it, and — in buildings with many units — what deposits other tenants hold.
- Right after signing, file a lease report if your lease is covered. Right after moving in, report your new address to immigration and make sure your lease has a fixed date (확정일자).
- When you leave, give notice in time, and arrange for the deposit transfer and the handover of keys to happen together.
Three ways to rent
월세 (monthly rent). You pay a refundable deposit, then rent every month. This is the usual arrangement for students renting a one-room. The deposit is commonly a few million won; in Seoul, ₩10 million is a common reference point.
전세 (lump-sum deposit). You pay a very large deposit — often a substantial share of the property’s value — and no monthly rent. The landlord returns it at the end. Because the amount is so large, and because deposit-fraud cases have hit 전세 tenants hard, it isn’t a sensible starting point for most newcomers.
반전세 (semi-전세). A larger deposit with lower monthly rent — somewhere between the two.
The rest of this guide focuses on 월세.
The deposit–rent seesaw
Deposit and rent move in opposite directions. For the same room, a landlord may offer ₩5 million with higher rent, or ₩10 million with lower rent. What you’re really choosing is how much cash to tie up versus how much to pay each month.
For reference: in Dabang listings registered in July 2026 for one-rooms of 33㎡ or less near ten major Seoul universities, on a ₩10 million deposit, the average was about ₩625,000 in rent plus ₩84,000 in management fees — roughly ₩709,000 a month, before electricity, gas and other bills that are billed separately (SBS Biz, August 2026). That’s a survey of listings near particular campuses, not an average for all of Seoul. Outside Seoul, prices are usually lower, but they vary by city, neighbourhood and building.
There’s also a legal cap on the rate used when part of the deposit in an existing lease — including one being renewed — is converted into monthly rent: the lower of 10% a year or the Bank of Korea base rate plus 2 percentage points. When you sign a new lease for the first time, the balance between deposit and rent is a matter of agreement.
What you pay, and when
A typical one-room rental involves several payments:
- Contract payment (계약금) — paid when you sign, commonly around 10% of the deposit. This is part of the deposit, not an extra cost. If you back out afterwards, you usually lose it; if the landlord backs out, they usually return double.
- Balance (잔금) — the rest of the deposit, paid on move-in day, typically in exchange for the keys or door code.
- First month’s rent — often paid in advance, on or around move-in.
- Agent’s fee (중개보수) — if you found the place through a licensed agent.
- Management fee (관리비) — monthly, on top of rent. Ask what it covers: some include water or internet, some only cleaning of shared areas. Electricity and gas are usually billed separately.
How much can the agent charge?
The agent’s fee for a residential lease has a legal ceiling, based on a “transaction amount.” For 월세, that amount is the deposit plus 100 times the monthly rent — or plus 70 times the rent if the first total is under ₩50 million.
| Transaction amount | Maximum rate | Cap |
|---|---|---|
| Under ₩50 million | 0.5% | ₩200,000 |
| ₩50 million – under ₩100 million | 0.4% | ₩300,000 |
| ₩100 million – under ₩600 million | 0.3% | — |
VAT may be added. Rates for officetels and larger amounts differ. The rate is a maximum, so it can be negotiated down.
Example: a ₩10 million deposit and ₩600,000 rent gives ₩10 million + (₩600,000 × 100) = ₩70 million. At 0.4%, the maximum fee is ₩280,000. Ask for a receipt.
Paying a large sum
If your Korean bank account is still transaction-limited, a multi-million-won transfer may exceed your daily limit. Talk to your branch well before the payment date: How to Open a Bank Account in Korea.
Before you pay anything: four checks
1. Who owns it? Get the property registry (등기부등본) — anyone can view or issue it online through the Internet Registry Office for a small fee. The owner’s name should match the person signing, or the person signing should have written authority from the owner. The account you pay into should belong to the owner or someone with documented authority to receive the money.
2. What debts are against it? The second section of the registry (을구) shows mortgages and other rights secured against the property. A mortgage isn’t unusual, but a large one matters: if the property is sold at auction, registered creditors ahead of you are repaid first.
3. Who else has a deposit? This is the check students most often miss. Many student one-rooms are in multi-unit houses (다가구주택), where the whole building is a single registered property with one owner and many tenants. Other tenants’ deposits don’t appear on the registry, but tenants with earlier dates may be repaid before you. Since 2023, landlords must show prospective tenants, at signing, the fixed-date and deposit information for the property and their national and local tax payment certificates — or consent to you viewing that information yourself. Ask for it.
4. Does the arithmetic work? Add the registered debts and the deposits ahead of you, then compare the total with what the building is realistically worth. If the total comes close to the value, your deposit is at risk even if everything is legal.
If any of this is unclear, ask the agent to explain the registry to you line by line before you sign — that’s part of their job. Common scam patterns are a separate guide, coming soon.
Right after signing
File a housing lease report (임대차 신고) if your lease is covered. In covered areas — which include the Seoul metropolitan area, metropolitan cities such as Busan, and other cities — leases with a deposit over ₩60 million or monthly rent over ₩300,000 must be reported within 30 days of the contract date, not of moving in. Many student one-rooms in Seoul cross the rent threshold. If you submit the lease contract with the report, the lease is given a fixed date (확정일자) automatically. Ask your agent who files it.
Right after moving in
Three things work together here, and they do different jobs:
- Moving in (점유). You have to actually be living there.
- Reporting your address. For a foreign resident, your alien registration — or, if you move after registering, a change-of-address report to immigration, due within 15 days of moving — has legal effect corresponding to a Korean’s resident registration move (전입신고). See Getting Your ARC.
- A fixed date (확정일자) on your lease — from a community service centre or online, unless you already got one through the lease report.
Moving in plus the address report gives you opposability (대항력): the right to assert your lease against a new owner. In principle, it takes effect from 00:00 on the day after both are complete — not the moment you finish the paperwork. Adding a fixed date gives you priority repayment (우선변제권): a place in the queue to be repaid if the property is auctioned. A fixed date on its own doesn’t complete your protection; it works together with moving in and reporting your address.
So report promptly. The 15 days is a deadline, not a waiting period.
The small-tenant safety net
If the property is auctioned, tenants with small deposits may be repaid a limited amount ahead of other creditors (최우선변제).
| Region | Deposit must be at or below | Maximum preferential repayment |
|---|---|---|
| Seoul | ₩165 million | ₩55 million |
| Seoul-area “overcrowding control” districts (excluding Seoul), plus Sejong, Yongin, Hwaseong and Gimpo | ₩145 million | ₩48 million |
| Metropolitan cities such as Busan (excluding areas within the overcrowding control districts and their county areas, 군), plus Ansan, Gwangju (Gyeonggi), Paju, Icheon and Pyeongtaek | ₩85 million | ₩28 million |
| Elsewhere | ₩75 million | ₩25 million |
A few conditions apply:
- You must have moved in and reported your address before the auction was registered, and you must file a claim for distribution (배당요구) in the auction by the court’s deadline.
- The total paid to small tenants is limited to half the value of the property. If several small tenants claim, that amount is shared among them, so you may receive less than the maximum.
- The figures that apply depend on when the earliest mortgage or other security on the property was registered, not on when you signed — older mortgages can mean lower thresholds.
Treat this as a safety net, not a reason to skip the checks above. The official explanation is on the government’s legal information portal, easylaw.go.kr.
Deposit-return guarantees
Korea also has guarantee products that repay your deposit if the landlord can’t, offered by the Korea Housing & Urban Guarantee Corporation (HUG) and others. Foreign residents with an ARC can apply. They were designed mainly with 전세 in mind, and whether a small 월세 deposit in a particular building qualifies depends on the product and the property — ask before assuming you’re covered.
Getting your deposit back
Give notice in time. If you don’t want to renew, tell the landlord at least two months before the lease ends — in writing, by text or message you can keep. If neither side says anything, the lease may renew automatically on the same terms; after that, you can end it by giving three months’ notice.
Leaving early is different. A replacement tenant doesn’t by itself end your contract. Get the landlord’s agreement, the end date, who pays the agent’s fee for the next tenant, and when your deposit comes back — all in writing. (More in the housing comparison guide.)
On move-out day:
- Check the room with the landlord, and agree on any deductions.
- Settle the final management fee and utility bills. These are often deducted from the deposit.
- Expect deductions only for unpaid charges, damage beyond normal wear and tear, and anything else your contract clearly states (such as a cleaning fee you agreed to). Ordinary ageing — faded wallpaper, small marks — isn’t your damage.
- Compare the room with the photos and video you took on move-in day.
Make the exchange happen together. Returning the deposit and handing back the room are, in principle, simultaneous obligations: neither side has to go first. In practice, agree in advance that the transfer and the handover of keys or door code will happen at the same time, and don’t finish the handover without confirming the money has arrived.
Don’t change your address before it’s settled. Your protection depends on living there and keeping your registered address. If you move out and report a new address while the deposit is still outstanding, you can lose your place in the queue.
If your deposit isn’t returned
- Consider a lease registration order (임차권등기명령). If the lease has ended and the deposit still hasn’t been returned, you can apply to the court for this order. Once the lease registration actually appears on the property registry, you keep your opposability and priority even if you move out and change your address. Until it appears, keep living there and keep your registered address — applying alone isn’t enough.
- Put your demand in writing. A formal certified letter (내용증명) creates a record.
- Get advice and support. The Housing Lease Dispute Mediation Committee handles deposit disputes at low or no cost, and the Korea Legal Aid Corporation (132) offers legal consultation. For help in other languages, the Immigration Contact Center (1345) can point you in the right direction. Your university’s international office may also know a lawyer used to helping students.
FAQ
Can I pay the deposit before I arrive in Korea? It’s possible, but risky. You can’t check the room, and a remote transfer to someone you can’t verify is exactly how deposit scams work. If you must, use an agent your university recommends and see the room by live video first.
Do I earn interest on my deposit? No. The landlord holds it; you get the same amount back, minus any agreed deductions.
Can my deposit be sent abroad when I leave Korea? Usually it’s returned to your Korean account; you then send it home yourself. Overseas transfers can require extra documents. See How to Open a Bank Account in Korea.
Is a bigger deposit safer, since the rent is lower? Not by itself. A bigger deposit is more money at risk. Choose the amount after doing the checks, not instead of them.
Should I consider 전세? For a first year as a student, usually not. The amounts are large, the checks are more demanding, and most student housing is offered on 월세 anyway.
The deposit system looks intimidating until you see it for what it is: a large sum you leave with your landlord for the length of the contract. Then the questions become obvious — who are you leaving it with, who else has a claim on that building, and how do you get it back?
