In Nov. last year, transactions in Seoul's office sales market fell by more than 70% from the previous month. The vacancy rate of office buildings also rose from the previous month, extending the slump in transactions.
Artificial intelligence (AI)-based commercial real estate comprehensive service corporations RealtyPlanet announced on the 13th a report on trends in Seoul's office sales and rental market for Nov. 2025.
According to the report, the total transaction amount in Seoul's office sales market in Nov. was 262.7 billion won, down 72.6% from the previous month (959.4 billion won). The office transaction amount also fell 94.7% over the same period, from 507.0 billion won to 27.0 billion won. The number of sales was 11 in total, up three from the previous month (eight). However, as transactions were made at relatively lower price levels, the total transaction amount decreased from the previous month.
The office building that transacted at the highest price in Nov. was "Premier Place (167.0 billion won)" in Mugyo-dong, Jung District. It was followed by "Yangyu Building (32.9 billion won)" in Daechi-dong, Gangnam District, and "B&M Building (19.8 billion won)" in Nonhyeon-dong, Gangnam District.
Seoul's office market in Nov. showed a sluggish trend as both transaction volume and transaction amount fell from the previous month. Transaction volume dropped 42.2%, from 128 deals to 74, and the transaction amount fell 94.7% to 27.0 billion won from 507.0 billion won. Compared with the same month a year earlier (236 deals·137.0 billion won), they decreased 68.6% and 80.3%, respectively.
Meanwhile, the vacancy rate of Seoul office buildings was tallied at 3.6%. The figure was up 0.09% from the previous month.
Jung Su-min, CEO of RealtyPlanet, said, "In Nov., the transaction volume in Seoul's office building sales market increased from the previous month, but transactions centered on small and midsize assets at relatively lower price levels continued, leading to a sharp decline in the total transaction amount."
