The Seoul housing rental market is undergoing a fundamental transformation, with monthly rent contracts reaching an unprecedented 70.5% in the first quarter of 2026.
This rapid shift, often called 'Wolse-hwa' (the shift to monthly rent), is not a sudden event but the result of several interconnected pressures that have been building over time. Let's explore the three primary drivers behind this trend.
First is the high-interest-rate environment. The Bank of Korea has held its policy rate at 2.50% for an extended period, including the latest freeze in April 2026. This makes borrowing expensive. For tenants, the interest on a large 'jeonse' loan has become a heavy burden. For landlords, high mortgage rates increase their own financing costs. In this situation, receiving a steady monthly rent becomes a more financially stable option for landlords to manage cash flow and cover their expenses, compared to a large, one-time jeonse deposit that doesn't generate regular income.
Second, a significant tax shock has pushed landlords further toward monthly rentals. In March 2026, the government announced a sharp 18.67% increase in the officially assessed prices of apartments in Seoul. This directly translates to higher property and comprehensive real estate taxes. Faced with a sudden jump in their tax bills, landlords have a stronger incentive to secure a consistent stream of cash income to cover these new liabilities, making monthly rent contracts far more appealing.
Third, there's a severe supply-demand imbalance in the jeonse market. The Jeonse Supply-Demand Index soared to 176.7, indicating an extreme shortage of available jeonse listings. This scarcity is compounded by a projected 33% decline in new apartment completions in Seoul for 2026. With fewer jeonse options available, tenants are naturally pushed toward the more abundant monthly or semi-monthly rental contracts. These factors combined create a powerful force, reshaping the rental landscape from a deposit-based system to one dominated by monthly payments.

- Officially Assessed Property Price: The government's valuation of a property, used as the basis for calculating property taxes. A higher price leads to a higher tax bill.
