Seoul's market for low-rise multi-unit housing strengthened in the second quarter of 2026, with 11,536 transactions worth a combined 4.93 trillion won ($3.6 billion), the highest level in about five years since the second quarter of 2021. Market data compiled by BudongsanPlanet from Ministry of Land, Infrastructure and Transport transaction records showed sales volume rose 11.7% from the previous quarter and 24.4% from a year earlier, while transaction value increased 12.1% quarter on quarter and 31.1% year on year. Activity was strongest in April before easing through May and June, and most of Seoul's districts recorded gains, led by Nowon, Gangbuk and Dobong. The rental market moved the other way. Total rental deals fell 13.7% from the previous quarter to 33,806, with jeonse (a lump-sum deposit lease system) down 8.0% and monthly-rent contracts down 16.9%. Monthly rent still accounted for 61.4% of rental transactions. BudongsanPlanet CEO Jung Soo-min said sales volume and value increased in the quarter, but average deal size shrank after April, while falling rental volumes contrasted with rising jeonse deposits and a higher jeonse-to-price ratio, signaling a heavier burden for tenants even as jeonse transactions declined.
