보증금 means a security deposit for a rental.

In Korean housing, the deposit is often a very important part of the contract, sometimes much larger than what English speakers expect. So when someone says 보증금이 낮다, they mean the deposit is low or the required deposit is not very high.

낮다 means to be low, and it is commonly used for things like:

• prices
• numbers
• levels
• fees
• deposits

So 보증금이 낮다 literally means the deposit is low.

A native English speaker might expect something like small, but Korean usually uses 낮다 for amounts or levels like this.

For comparison:

• 가격이 낮다 = the price is low
• 월세가 낮다 = the monthly rent is low
• 보증금이 낮다 = the deposit is low

This is a very common Korean pattern.

• 집은: 은/는 marks the topic
• 보증금이, 방이: 이/가 marks the subject of each description

So the sentence is structured like this:

• 이 집은 = As for this place / this home
• 보증금이 낮지만 = the deposit is low, but
• 방이 조금 좁아 = the room is a little small/narrow

In other words, 이 집은 sets the overall topic, and then the sentence gives two facts about that place.

Yes, it could:

• 이 집은 보증금은 낮지만 방은 조금 좁아.

This version sounds more contrastive, as if you are clearly comparing two aspects:

• the deposit, at least, is low
• but the room, on the other hand, is a little small

The original with 이/가 sounds more neutral and descriptive.
The version with 은/는 gives stronger contrast.

지만 means but or although.

It attaches to the stem of a verb or adjective:

• 낮다 → stem 낮-
• 낮지만 = is low, but...

So:

• 보증금이 낮지만 = the deposit is low, but...

It connects the first clause to the second clause.

좁아 is the casual/non-polite ending.

Compare:

• 좁아 = casual
• 좁아요 = polite

So this sentence sounds like something you might say to:

• a friend
• a sibling
• someone younger
• someone you are close to

A more polite version would be:

• 이 집은 보증금이 낮지만 방이 조금 좁아요.

Also note that politeness is mainly shown at the end of the sentence. The connector 지만 itself does not make the sentence polite or casual.

This is a very good question.

• 좁다 = narrow / cramped
• 작다 = small

For a room, both can sometimes work, but the nuance is different:

• 방이 좁아 = the room feels cramped or lacks width/space
• 방이 작아 = the room is small in overall size

In housing descriptions, 좁다 is very common because people often care about whether a room feels spacious enough to use comfortably.

조금 means a little.

So:

• 방이 좁아 = the room is narrow/small
• 방이 조금 좁아 = the room is a little narrow/small

It softens the statement. Instead of sounding very harsh, it sounds more moderate, like:

• It’s a bit small
• It’s a little cramped

This is very common in Korean when giving opinions, especially about housing, appearance, or quality.

Not necessarily.

집 literally means house/home, but in everyday Korean it can also refer more broadly to someone’s place, including:

• a house
• an apartment
• a studio
• a rented place to live

So in a sentence like this, 이 집 often means this place or this apartment/home, not strictly a detached house.

Because each clause has its own subject.

The sentence is really two linked parts:

1. 보증금이 낮지만
   = the deposit is low, but

2. 방이 조금 좁아
   = the room is a little small

Each part describes a different thing, so each one gets its own subject marker.

This is very normal in Korean.

Yes. That is exactly the feeling.

The structure is:

• positive point: 보증금이 낮지만 = the deposit is low
• negative point: 방이 조금 좁아 = the room is a little small

So it sounds like someone is evaluating the place and saying:

• One good thing is the low deposit
• One downside is the small room

This kind of balanced description is extremely common in Korean when talking about homes, restaurants, products, and other things being reviewed or compared.
