The average new mortgage loan per person in South Korea surged to a record high of ₩229.39 million in the first quarter of 2026.
So, why did this happen now? It wasn't just one thing, but rather a perfect alignment of four key factors: tax policies, upcoming regulations, interest rates, and market momentum. This created a unique window of opportunity, especially for homebuyers in their 30s looking at properties in the Seoul metropolitan area.
Let's break down the causal chain. First, a temporary capital gains tax deferral for multi-home owners was set to expire on May 10. This encouraged many to sell their mid-to-low priced properties during the first quarter, increasing the available housing supply. Second, financial authorities announced plans to tighten DSR (Debt Service Ratio) rules from April 1. This created a sense of urgency, prompting creditworthy buyers, particularly those in their 30s, to secure loans before the criteria became stricter.
At the same time, the interest rate environment was uniquely favorable. The Bank of Korea held its policy rate steady at 2.50%, which prevented a sharp rise in borrowing costs. While rates weren't falling, the availability of long-term, fixed-rate policy mortgage loans like the 'Bogeumjari-ron' made large loans feel more affordable. With terms extending up to 50 years, the monthly payments on a ₩230 million loan could be less than ₩1 million, a manageable sum for many dual-income households in their 30s.
Finally, all this demand was channeled into specific areas. As apartment prices in Seoul continued their steady climb, buyers turned their attention to the more affordable outskirts, such as Gyeonggi and Incheon. This shift in demand, combined with the increased supply of homes and accessible long-term financing, drove up the average loan size in these regions, ultimately pushing the national average to its record high.
