Security deposit, types of home, districts and rents: the rules of the Seoul rental market for a new arrival.

Finding a home in Seoul means understanding a rental system that is nothing like the French one. Almost everything revolves around the security deposit: either a moderate deposit with a monthly rent (the wolse), or a very large deposit with no rent (the jeonse). For a newly arrived foreigner, the wolse is generally the only realistic option.
The market is tight and prices are rising. According to the monthly report from the Dabang platform, a studio of 33 m² or less in a small residential building rented for an average of 710,000 won per month in Seoul in March 2026, based on a deposit of 10 million won. In August 2026, the Korea JoongAng Daily described young Koreans forced to move away from their university or office to pay less. This guide sets out the types of home, the districts, the budgets and the checks to make before signing.

This is the most common arrangement for foreigners. You pay a security deposit (bogeum) at signing, then rent each month. The deposit is returned at the end of the lease if the home is handed back in good condition. The ratio between deposit and rent is negotiable: a higher deposit lowers the rent, and vice versa. That is why Korean rent statistics always state the reference deposit, often 10 million won.
With the jeonse, the tenant pays a very large sum, generally 50 to 80% of the value of the home, and pays no rent for the duration of the lease, often two years. For a studio, the average jeonse deposit reached 213.86 million won in Seoul in March 2026 according to Dabang. This arrangement is declining: tighter credit has reduced supply and shifted demand to the wolse, which pushes monthly rents up. For a foreigner with no banking history in Korea, the jeonse is both hard to finance and risky if the landlord cannot pay the deposit back.
Detached houses are rare in the central districts. If you want space, look at the large apartment complexes rather than a house.
Seoul has 25 districts (gu). The Dabang report of March 2026 lets you compare them: for a studio, Gangnam-gu has an average rent at 141% of the city average, Seocho-gu and Seongdong-gu at 122%, Yongsan-gu at 118%. Only nine districts are above the average.
Seoul's historic international quarter, with a dense foreign community. Itaewon is lively and cosmopolitan, Hannam-dong more residential and upmarket. Rents here are high.
The wealthiest area of the city, south of the Han River, with business centers and international schools. It is the most expensive district for a studio.
Residential and quiet, popular with families. Seorae Village is home to a large French community and international schools.
A university and creative quarter, more affordable than Gangnam. It suits students and young professionals well.
Jongno-gu, around Bukchon and Insadong, is the historic heart, close to the royal palaces, with housing in villas or renovated hanok. Seongdong-gu, around Seongsu-dong, is a neighborhood in transformation, already above the city average for studios.
Near universities, studio rents climb fast. According to Dabang, cited by the Korea JoongAng Daily, the average studio rented for 738,000 won per month in January 2026 around the humanities campus of Sungkyunkwan University, up 18.1% in a year, and 711,000 won near Ewha University. In July 2026, the average rent for a studio near the main universities was 625,000 won, plus 84,000 won in maintenance fees on average.
Good homes go fast, especially before the university start in March and during the summer. Starting with a goshiwon or a short-term furnished rental gives you time to visit without signing under pressure.
The language, the deposit system and contracts in Korean make searching from abroad difficult. In Korea, real estate agents often represent the landlord as much as the tenant. A Remoters home finder based in Seoul works for you: they search according to your budget and your district, visit, check the land registry, review the lease and go with you until you get the keys. The first conversation and the quote are free.
