Renting in Seoul: What the Deposit Really Tells You
Someone moving to Seoul for an internship asked a good question on Reddit recently. They’d been browsing Facebook housing groups and kept seeing the same numbers:
“Deposit around 1–2 million KRW · Monthly rent around 300,000 KRW · Plus management fees ~100,000 KRW … Are prices like this normal/legit for very small one-rooms in Seoul, or should I be suspicious?”
The honest answer is the one the thread eventually landed on: those numbers are real, but they are almost certainly not describing a one-room studio.
What the deposit is actually telling you
Korean rentals trade deposit against rent. A bigger deposit buys a lower monthly payment, and you can usually negotiate along that line. Which means a low deposit on its own means nothing — it’s low deposit and low rent together that gives the game away.
Rough market shape in Seoul, as of 2026:
| What it is | Deposit | Monthly | What you get |
|---|---|---|---|
| 고시원 / 고시텔 | Little or none | ₩300,000–500,000 | A bed, a desk, sometimes a tiny shower. Kitchen and often bathroom shared |
| One-room (원룸) | From around ₩10,000,000 | ₩400,000–700,000+ | Your own room, kitchenette and bathroom |
| Officetel | ₩10,000,000+ | ₩700,000+ | Better building, lift, security, higher 관리비 |
A ₩1–2M deposit with ₩300,000 rent is goshiwon territory, not a studio. Goshiwons are a real and legitimate housing type — students and workers live in them for years — but they are a single small room, often windowless, with shared facilities. Nobody is scamming you. The listing is just being generously described.
For an actual one-room in Seoul, plan on ₩10,000,000 as the realistic floor for the deposit. Below that, either the deposit has been converted into much higher rent, or you’re looking at a different category of housing entirely.
This matters most for newcomers, because the deposit is the number that decides whether you can move at all — and it’s the reason coliving and share houses exist, since they take deposits sized in the low millions rather than the low tens of millions.
Read the management fee before the rent
관리비 — the monthly management fee — is where the real cost hides. ₩100,000 is normal, but the number is meaningless until you know what’s inside it.
Ask explicitly: does it include water, electricity, gas, internet, cleaning of common areas? A ₩50,000 fee that covers nothing and a ₩120,000 fee that covers water, internet and heating are very different propositions, and the cheaper-looking one often costs more.
Use an agent, and know why
The strong advice from residents who’ve done this: go through a licensed agent (부동산).
It costs a fee. What it buys you is a contract that follows the standard form, paperwork that’s actually filed, and — the part people underestimate — a witness who is not your landlord.
Foreign tenants in these threads describe landlords who assumed they didn’t know the rules: demanding extra payments after the fact, or objecting to how much water and electricity they used. A signed agency contract is the thing that ends those conversations.
Two more contract facts worth knowing before you sit down:
- The standard residential lease is two years. One-rooms and officetels often do one year, but shorter than that is a negotiation, not a norm.
- 가계약금 — a small holding deposit to reserve a unit while the contract is prepared — is normal practice. Confirm in writing what happens to it if either side walks away.
Now the ten minutes that matter
You’ll get one viewing, and it will feel rushed. Here’s the order we’d go in.
Before you walk in
- Which floor, and is it below ground? 반지하 (semi-basement) units are cheaper for reasons you will feel in July.
- Which way does it face? North-facing rooms stay cold and damp. Ask, or check which way the sun is coming from.
- How far is the station, walking, uphill? Listings measure distance generously and rarely mention the hill.
The two-minute physical test

Water pressure. Turn the shower on and flush the toilet at the same time. If the shower dies, that’s your morning, every morning.

Hot water. Run the tap and wait. How long until it’s actually hot? And find the boiler: there’s a plate on it with a manufacture date. A boiler over about ten years old is near the end of its life — we wrote about what that means and who pays.
Mobile signal. Check your phone in the room, not the hallway. Thick concrete and a back-alley position can leave you with no bars where you sleep.
The wall, the ceiling, the window
This is where a cheap flat tells the truth.
Crouch at the wall base and smell. Damp sits low. Then look at the very bottom edge of the wallpaper, especially in corners and on exterior walls.

White crystalline deposits are worse than black spots. That’s efflorescence — salt carried out of the concrete by water moving through the structure, not just surface damp.

The full version of this check — including why Korean interiors hide it so well and what to ask the landlord — is here.
Look up too. Brown rings or a sagging cornice mean water has come from above at some point. Leaks between floors are common and slow to resolve, and a stain is evidence that the building has form.
Open the windows. Do they actually open, is there an insect screen, and does anything about the frame look like it sweats in winter? Condensation marks around window frames are the early version of the mould above.
Before you sign
Photograph everything, with dates. Every mark, scuff, stain and appliance, on move-in day.
This is the single highest-value ten minutes of the whole process, and it has nothing to do with the flat’s quality: it is your evidence when you move out and the deposit conversation starts. Existing damage that you didn’t record is, by default, damage you caused.
A note on pets
Since it comes up constantly: “pet-friendly” in Korean listings usually means small dogs. Under roughly 5–10kg, in practice. A large breed narrows your options dramatically regardless of budget, and it needs to be the first thing you tell an agent — not something that emerges at the viewing.
The Korean part
Everything above happens in Korean: the listing, the agent, the contract, the landlord’s answer about the boiler, the negotiation over the management fee.
We do two things here. Through our anything-else concierge service we come to viewings with you — translating, asking the questions above, and telling you honestly what we’d walk away from. And when you’ve signed, our moving service handles the van, the crew and the disposal of whatever the last tenant left behind.

The one-line version: a ₩1–2M deposit means goshiwon, a real one-room starts around ₩10M, the management fee matters more than the rent, and ten minutes with the shower running and your nose at the skirting board will tell you more than any listing photo.
