This is the second of two posts on finding a place in Korea. The first one was about which kind of room fits your stay [→ Part 1]. This one is about what it costs, starting with the number that catches almost everyone off guard.
You're browsing listings, you find a room that looks perfect, the monthly rent is reasonable. Then you see another number. A big one. Bigger than a month's rent. Bigger than several months' rent.
That's the 보증금 (bojeung-geum), and understanding it is the difference between a smooth move and a very stressful one.
Let's decode the whole system.
First: the money words
Korean rentals are built from two numbers, not one.
보증금 (bojeung-geum): the deposit.
A lump sum you pay before moving in, held by the landlord and returned when you leave. Unlike deposits in many countries, this can be large. Think in terms of months of rent, sometimes far more.
월세 (wolse): monthly rent.
The amount you pay each month. Here's the key relationship: a bigger deposit usually means lower monthly rent. The two trade off against each other, and it's often negotiable.
전세 (jeonse): the deposit-only system.
A uniquely Korean arrangement: you pay a very large deposit, pay no monthly rent at all, and get the deposit back at the end. Contracts usually run two years. It sounds amazing. It also requires a huge amount of cash and carries real risk if things go wrong with the landlord or the property.
⚠️ Honest advice: 전세 is not a beginner's option. A two-year contract alone rules it out for most working holiday and exchange stays. If you're new to Korea or staying under a year, you almost certainly want a small-deposit 월세 arrangement instead.
Before anything else: can you register that address?
This is the step nobody warns you about, and it can undo everything else.
Your registered address is what ties you to your immigration office, your bank and your mail. When you register as a resident, or when you move later, you file that address with immigration. Not every room can be registered. Some buildings and some arrangements won't support it, and landlords don't always volunteer this.
So before you pay anything, ask directly: can I register my residence at this address? If the answer is vague, treat that as a no and keep looking.
And once you've moved in somewhere: if you change address later, you have 15 days to report it.
The rule that will save you money
Never send money for a place you haven't seen in person.
Not a deposit, not a "reservation fee," not a "holding payment." Photos are photos. Rooms differ from photos. And a landlord or agent who pressures you to transfer money before you've stood in the room is a landlord you don't want.
What the rent number doesn't include
Monthly rent is rarely the whole monthly cost. Budget for these on top:
- 관리비: the building maintenance fee, usually quoted separately
- Utilities: electricity, water, gas, internet, often billed individually
- Whether any of these are bundled into your rent, and which
Work out your cost from rent and 관리비 together. Some rooms look cheap on rent and carry a high maintenance fee.
Read the contract terms, not just the price
Two questions that matter more than they sound:
How long is the contract? Fixed terms are normal.
What happens if you leave early? You may owe a penalty, and your deposit may not come back quickly. Working holiday plans change, jobs change, people go home early. Ask before you sign, not after.
For shared housing of any kind (goshiwon, boarding house, share house, homestay), also ask about the house rules: cleaning, noise, guests, shared kitchen use. These decide how liveable a place is more than the square footage does.
Before you sign: protect your deposit
The deposit is the largest amount of money most newcomers hand over in Korea. Korea has official procedures designed to protect tenants' deposits: registering your residence and getting your contract officially dated.
Do not skip this step, and do not take a stranger's word for how it works. Ask your university's international office, your company's HR, or your local district office (주민센터) what exactly you need to do as a foreign resident. This is the one part of moving where getting the details right is worth an afternoon of asking questions.
Words for the viewing
| Korean | Sounds like | Meaning |
|---|---|---|
| 보증금 | bo-jeung-geum | deposit |
| 월세 | wol-se | monthly rent |
| 관리비 | gwal-li-bi | maintenance fee (ask, it's often separate!) |
| 계약서 | gye-yak-seo | contract |
| 집주인 | jip-ju-in | landlord |
| 부동산 | bu-dong-san | real estate office |
| 풀옵션 | pul-op-syeon | "full option": comes furnished with appliances |
| 방 보러 왔어요 | bang boreo wasseoyo | "I'm here to see a room." |
Two questions to always ask:
관리비 얼마예요? (gwallibi eolmayeyo?) "How much is the maintenance fee?"
여기 전입신고 돼요? (yeogi jeonipsingo dwaeyo?) "Can I register my address here?"
The short version
- 보증금 is bigger than you expect. Budget for it before you fly.
- Bigger deposit = lower monthly rent. Often negotiable.
- 전세 is not for beginners.
- Ask whether you can register your address there, before you pay
- Never wire money for a room you haven't seen
- Ask for the total monthly cost, not just the rent
- Ask what happens if you leave early
- Ask officially how to protect your deposit. Don't guess
Find the room second. Find your footing first. 🏠
Still deciding what kind of room you want? That's the other half of this pair.
