Seoul Apartment Jeonse Dries Up, 3 Reasons Why 30s Are Accelerating Migration to Gyeonggi's 'Semiconductor Belt'
With Seoul apartment jeonse listings plummeting and monthly rent conversions accelerating, high-income 30s are increasingly migrating to the semiconductor belt in southern Gyeonggi Province.

As Seoul apartment jeonse (lump-sum deposit lease) listings plummet and the conversion of deposits to monthly rent accelerates, growing housing insecurity is driving a wave of 30-something end-users to migrate toward the 'semiconductor belt' in southern Gyeonggi Province. The 'exodus from Seoul' is materializing as people seek to avoid high housing costs in favor of southern metropolitan areas equipped with quality jobs and infrastructure.
Deepening Seoul Jeonse Shortage and Accelerated Monthly Rent Conversions
Currently, Seoul's jeonse shortage is nearing the levels of the 2021 'jeonse crisis'. The absolute number of available jeonse listings has dwindled due to a sharp decline in new apartment move-in volumes, coupled with policy factors like stricter real-residence requirements that have effectively blocked 'gap investments'. Furthermore, the burden of higher jeonse loan interest rates has accelerated the 'monthly rent-ification of jeonse', where parts of the deposit are converted to monthly rent, deepening tenants' woes.
30-Something End-Users Flocking to Gyeonggi's Semiconductor Belt
In contrast, southern Gyeonggi regions—such as Hwaseong (Dongtan), Yongin, Suwon, and Pyeongtaek, collectively known as the 'semiconductor belt'—have emerged as the new core axis of the real estate market. The concentration of the demographic in their 30s in this region can be summarized by three key reasons:
- Concentration of High-Income Jobs: The development of semiconductor clusters centered around Samsung Electronics and SK Hynix has led to a massive influx of high-income employees with significant financial backing.
This movement of high-income demand is driving up housing prices in southern Gyeonggi, and combined with the demand pushed out of Seoul, it is bringing about polarization and structural changes in the metropolitan real estate market.
Frequently Asked Questions (FAQ)
Q. What is the forecast for Seoul apartment jeonse prices in the second half of the year?
The drought in move-in volumes in Seoul is expected to continue in the second half of the year, so upward pressure on prices due to a lack of jeonse supply is projected to persist. If autumn moving season demand overlaps, the jeonse shortage could worsen further.
Q. Will housing prices in southern Gyeonggi continue to rise?
Backed by powerful job creation from the semiconductor cluster and the expansion of transportation networks like the GTX, the region is highly likely to show strong downward rigidity and an upward trend for the time being. However, fatigue from short-term spikes and whether the high-interest-rate stance is maintained remain variables.
