Gangnam asks fall up to 33% after Korea's tax overhaul, and the discounts are not clearing

Sellers in Seoul's most expensive apartment districts are cutting asking prices by billions of won, and since the government's recent tax overhaul the discounts have spread from Apgujeong to Banpo and Gaepo ^[1][2]. The consequence worth tracking is not the size of the cuts but that buyers have not taken them, while the rest of Seoul keeps rising ^[2].

The marker case: the lowest asking price for a 183-square-meter unit at Shin Hyundai in Apgujeong-dong stood at 8.59 billion won, or about $6.2 million, as of the 20th, according to the real estate industry ^[3]. That is 4.21 billion won, or 32.9%, below the record 12.8 billion won set in December last year, despite the unit being high-floor and south-facing ^[4]. It is also close to the actual transaction price at the end of 2024 and 1.46 billion won under the 10.05 billion won that a sale logged on the 22nd of last month ^[5], a markdown of roughly 14.5% against a print less than a month old ^[6].

Seocho-gu shows the same pattern in smaller amounts. An 84-square-meter unit at Banpo Xi is listed at around 4.3 billion won, about 900 million won below its January record ^[7], implying a discount near 17% ^[8]. Comparable units at Acro River Park once traded as high as 5.6 billion won and are now listed around 5 billion won, 500 million to 600 million won lower ^[9].

Closed prices have moved far less than asks. One 84-square-meter unit at Acro River Park changed hands at 5.39 billion won, 200 million to 300 million won under the previous deal ^[10], which is only about 3.8% below the 5.6 billion won peak ^[11]. So the 33% figure is a seller's ask, not a clearing level.

Volume is where the break shows. Between the 1st and the 20th of this month, Apgujeong-dong reported a single sale, a 116-square-meter unit at Hanyang No. 3, against four in the same period last year, and Banpo-dong reported two against 12 ^[12][13] - declines of 75% and roughly 83% ^[14]. Counts may rise because the reporting deadline has not passed, but the market looks quiet ^[15]. A broker near Gaepo Xi Presidence said six or seven new listings had come out since the tax overhaul with no sale closing in two or three weeks, adding that even after cuts of hundreds of millions of won no loans are available, so buyers look and delay ^[16]. A brokerage head near Maple Xi in Jamwon-dong said inquiries for cheap listings are steady but are not turning into contracts, with tax-driven rushed sales increasing mainly among older owners ^[17]. A broker near Banpo said the overhaul of the special long-term holding deduction should bring more owners to sell ^[18].

The indexes agree, narrowly. In the third week of August the Korea Real Estate Board recorded Gangnam-gu down 0.05% and Seocho-gu down 0.09%, a second straight weekly decline with the drops widening, and Songpa-gu's gain slowing to 0.10% ^[19][20]. Seoul overall rose 0.22%, a wider gain than the prior week on northern and outlying districts ^[21], leaving Gangnam-gu about 27 basis points below the citywide print in a single week ^[22]. Nam Hyeok-woo, a real estate researcher at Woori Bank, said discounted listings from single-home owners who decided to sell after the tax reform plan continue to appear, and that apartments in the high 4-billion-won range face expected increases in comprehensive real estate tax and capital gains tax, pressuring more supply into Gangnam's core ^[23][24].

Watch whether closed prices migrate toward the cut asks or the listings get pulled; whether the August transaction counts fill in once reporting closes; whether loan availability stays the binding constraint at these tickets; and whether Songpa turns negative, extending the divergence between high-end and mid-priced Seoul ^[25].
