Housing Near Seoul International School (SIS)
Seoul International School sits in Seongnam, in Gyeonggi-do, southeast of Seoul rather than inside the city. That single fact shapes the whole housing decision: families who assume they will live in Gangnam and drive out each morning usually revise the plan once they have done the trip in rush hour. This guide covers the neighborhoods that actually work for an SIS commute, what kinds of homes are available in them, and what changes when you sign a lease in Gyeonggi instead of Seoul.

Where SIS families live
The closest housing sits on the Sujeong-gu side of Seongnam, near Bokjeong, and it is the shortest school run of any option. Most international families, though, settle a little further south in Bundang and Pangyo, where the apartment stock is newer, the blocks are laid out around parks and schools, and there is an established foreign-resident community. Bundang trades a slightly longer drive for considerably more housing choice.
Some families do stay in southeast Seoul — Songpa and Gangnam — and commute outward. It is a real option if one parent works in central Seoul, but treat the morning drive as the deciding variable and test it before you commit to a lease.
Getting to school
Bokjeong Station connects Seongnam to Seoul on Line 8 and the Suin–Bundang Line, and the Bundang corridor runs north into Gangnam, so a Seongnam address is not a cut-off one. For the school run itself, most families drive or use a school bus route rather than the subway; when you view a home, ask which routes serve that specific complex, because coverage varies block to block and is the detail most likely to change your shortlist.
Home types that fit
This is apartment country. Gyeonggi complexes are where you find the three- and four-bedroom family layouts that are scarce and expensive inside Seoul — see apartments and the 3-bedroom filter for what is currently listed. Families arriving before their shipment lands often start in a furnished home and move once. Houses exist in the older Seongnam neighborhoods but are a much thinner market than the apartment stock.
Leases in Gyeonggi vs Seoul
The mechanics are the same — jeonse (전세), a large refundable deposit with no monthly rent, or wolse (월세), a smaller deposit plus monthly rent — but the numbers are not. Deposits outside Seoul are generally lower for comparable space, which is the main reason the family-sized home your budget could not reach in Gangnam is reachable in Bundang. Read jeonse vs wolse vs buying before you choose between the two, and renting in Seoul as a foreigner for the paperwork, which is identical in Gyeonggi.
Timing your search
Housing demand around the international schools follows the school calendar, not the Korean moving season, and tightens sharply in the weeks before a new academic year. If your start date is fixed, begin looking well ahead of it — the difference between searching early and searching late is mostly a difference in how much choice you have, not in price.

Frequently Asked Questions
Where is Seoul International School?
It is in Seongnam, in Gyeonggi-do, southeast of Seoul rather than within the city itself. Most families live in Seongnam near Bokjeong, or a little further south in Bundang and Pangyo.
Do SIS families have to live in Gyeonggi?
No. Some families live in southeast Seoul, in Songpa or Gangnam, and commute outward. It works best when one parent also works in central Seoul. Drive the route in morning traffic before you sign anything, because the commute is what usually decides this.
Is housing cheaper near SIS than in Gangnam?
Deposits and rents in Gyeonggi are generally lower than in central Seoul for a comparable amount of space, which is why family-sized apartments that are out of reach in Gangnam are often reachable in Bundang. Check current listings for live figures rather than relying on an average.
What kind of homes are available near the school?
Overwhelmingly apartments. Gyeonggi complexes hold most of the three- and four-bedroom family layouts, which are scarce inside Seoul. Furnished homes are worth considering if you arrive before your shipment does. Houses exist in older Seongnam neighborhoods but form a much thinner market.
How does a Gyeonggi lease differ from a Seoul one?
The structure is identical — jeonse or wolse, with the same paperwork and the same protections. Only the numbers differ: deposits outside Seoul are typically lower for equivalent space.
