South Korea housing market 2026: prices, costs, FSBO

The freshest official read points clearly up. The Korea Real Estate Board's national house price index reached 101.04 in May 2026, climbing from 100.87 in April, a monthly gain of 0.30 percent. That is a rising market, and the momentum is fresher and stronger than older quarterly readings suggested. The national median home price sits around KRW 500 million, with the average closer to KRW 540 million, while Seoul's average apartment runs far higher, well over KRW 1.4 billion on most series and higher still on the newest-apartment measures.

Seoul is the engine. Through mid-May 2026, Seoul apartment prices were rising about 0.3 percent per week, with the week through May 18 up 0.31 percent, the fastest weekly rise since late January and the 68th consecutive week of gains. Nationally the weekly pace is far gentler, around 0.06 percent in the week through May 11, which is why the monthly national index advances modestly even as Seoul runs hot. Premium districts are the standout: Gangnam-gu apartments run roughly KRW 90 million to 108 million per pyeong depending on segment, well above a Seoul citywide level near KRW 16 million per square meter. Even there the picture is mixed, with some early-2026 reports showing Gangnam average transaction prices easing year on year as activity thinned.

Our own read of live listings shows how wide the range is. Across 11 mid-size 84-square-meter (30-pyeong) three-bedroom apartments we sampled in Seoul's Nowon-gu and Busan's Haeundae-gu in June 2026, the median asking price was about KRW 880 million, ranging from KRW 460 million to KRW 1.43 billion. Per-square-meter pricing in those districts ran roughly KRW 9 to 15 million, against a Seoul citywide average near KRW 16 million and Gangnam-gu around KRW 32 million per square meter. Rolling the May index forward one month at the recent monthly pace, our nowcast for June 2026 lands near index 101.3 and a national median around KRW 502 million, and that national figure likely understates Seoul, where weekly gains imply something closer to 1.2 percent per month.

Selling costs in Korea are low by international standards, and the reason is the regulated brokerage fee. On a sale, a seller's agent fee is capped by a sliding scale, in Seoul 0.4 percent of price for the KRW 200 million to 900 million band, rising to 0.5 to 0.7 percent for higher brackets, plus 10 percent VAT, and it is negotiable up to that ceiling. On an KRW 800 million sale at the 0.4 percent bracket, that is about KRW 3.52 million for your side including VAT, a fraction of US-style listing commissions.

Here is the structure that matters. The commission is split, meaning the buyer and the seller each pay their own agent separately, each up to the same regulated ceiling. The seller is not responsible for the buyer's agent fee, and vice versa, so your commission exposure as a seller is one capped side, not two. A judicial scrivener (beommusa) handling the closing and title transfer, plus the capital-gains filing, typically adds only KRW 300,000 to 700,000.

The real variable is tax on any profit. The seller's largest potential cost is capital-gains tax (yangdo sodeukse), a progressive tax on the gain after acquisition cost, improvements, and transfer costs, with a 10 percent local income surtax layered on top of the tax itself. A one-home owner-occupier who meets the holding and residence conditions is often largely or fully exempt, while multi-home owners and short holds can face high marginal rates and surcharges. Acquisition and registration tax is the buyer's cost, not the seller's, so it does not affect your net.

Owner-direct dealing, known as jikgeorae, is fully legal in South Korea. No law requires a licensed agent (gongin junggaesa) to transfer property, and direct deals are a growing feature of the market as sellers and buyers try to avoid even the relatively low brokerage fee. Large apartment portals are used heavily for price discovery, though their listings are still mostly agent-posted, while some consumer channels carry genuine owner-to-owner ads.

The trade-off is risk, not legality. Because there is no agent to verify the title and escrow the transaction, direct deals carry more fraud and contract exposure. The standard protections are straightforward and within an owner's control: independently pull the property registry (deunggibu deungbon) to confirm ownership and any liens before signing, and use a judicial scrivener for the closing and registration so the title transfer is done correctly.

The honest framing is this. A private sale in Korea saves your own side of the commission, up to roughly 0.4 to 0.7 percent of price depending on the bracket, on an 800 million won home that is about KRW 3.52 million at the 0.4 percent rate. It does not save the buyer's side, which was never yours to pay. The savings are smaller in absolute terms than in high-commission markets, but so is the work, since pricing data is unusually transparent here thanks to published actual-transaction records (the MOLIT register). If you already have a buyer or a clear comparable read, a direct deal is a reasonable choice.
