Seoul apartment prices rise for an 87th week, up 0.12% in October 2026

Seoul's apartment sale price index rose 0.12% in the week to 5 October 2026, an 87th straight weekly gain, while Gangnam, Seocho and Songpa fell.

The facts

• The Korea Real Estate Board's weekly Seoul apartment sale price index rose 0.12% in the week to 5 October 2026, published on 8 October; a week earlier it was 0.09%.
• That is an 87th consecutive weekly rise in the index.
• Seoul's jeonse index rose 0.16%, the same as the previous week. Jeonse is Korea's own rental form: a large deposit returned at the end of the term, with no or minimal monthly rent.
• Weekly declines: Gangnam -0.34%, Seocho -0.27%, Songpa -0.19%.
• Weekly gains: Gangbuk +0.35%, Dobong +0.32%, Nowon +0.31%.

What it means for your money

• Entry depends on the district now: the city-wide +0.12% covers districts moving in both directions.
• Purchase price and direction: the city is splitting. Gangbuk, Dobong and Nowon rose this week while Gangnam, Seocho and Songpa fell, and all six figures are weekly rates, not annual ones.
• Rental income and deposit: the 0.16% rise in the jeonse index moves the deposit amount, not a monthly rent. A bigger deposit means more cash at entry.
• An owner already in Seoul faces both directions at once: the 87-week run supports resale value, while Gangnam, Seocho and Songpa fell this week.

What to watch

• The release gives direction and pace, not a price level: no index base value, no transaction count, no price per square metre in won, no gross rental yield, no loan interest rates.
• The survey is weekly, and the next reading follows that rhythm.
