In Seoul, the rental market is still priced mainly through jeonse, the large refundable deposit that takes the place of ordinary monthly rent for many Korean apartments. KB Kookmin Bank's monthly housing-price series for October 2026, read from the KB Real Estate data hub, puts the average Seoul apartment jeonse at about ₩729 million. KB stores the series in units of 10,000 won. The October Seoul figure is 72,897.5 of those units, which is ₩728.98 million when shown the way Korean market notes usually round it. That October reading is a new high in the 13-month window available from the hub.

KB splits Seoul into 14 districts north of the Han River and 11 districts south of it. The northern group averaged about ₩603 million in October, or ₩602.81 million on the same rounding, which puts it above the ₩600 million mark. The southern group averaged about ₩842 million, or ₩841.78 million. Both groups were higher than in September on the same series.

Sale prices moved more slowly than in recent months on KB's apartment price index. Seoul's sale index rose 0.61% from September to October. The northern districts rose 0.90% and the southern districts 0.35%. The matching jeonse index for Seoul rose 0.50% on the month. Year-on-year, Seoul's sale index was up about 11.0% and its jeonse index about 9.2%.

These figures are KB's survey averages and indices for apartments, not a count of every signed contract. The hub responses used here carry an update stamp of 12 October 2026 and a monthly date list that includes October 2026. Secondary press notes that repeated the same averages were not used as the primary source.
