[In-Depth] Triple Strong Rent Prices: Supply Cliff and Monthly Rent Shift

As of July 5, 2026, South Korea's rental market is facing severe supply-demand imbalances and price volatility. The prolonged shortage of jeonse (lump-sum deposit) apartment listings in Seoul is rapidly spreading to major new cities in the Gyeonggi province. In particular, the 'triple strong' phenomenon—where purchase prices, jeonse prices, and monthly rents are rising simultaneously—is becoming entrenched, significantly increasing the actual housing burden on end-users.

Record-Low Move-in Volume and Accelerated Monthly Rent Shift

The core driver of the current rental market instability is the sharp decline in new housing supply. As of July 2026, the national scheduled apartment move-in volume has hit a 10-year low. With new supply effectively cut off, market inventory turnover has plummeted due to residential regulations emphasizing actual residency and the exercise of lease renewal rights.

The steep rise in jeonse deposits and persistent loan interest burdens have triggered structural changes in housing types. According to recent transaction data, the proportion of monthly rent contracts among new leases for Seoul apartments now exceeds 50%. As entry barriers to the jeonse market rise, tenants are increasingly being pushed into the monthly rental market, accelerating this structural shift.

Demand Migration to the Non-Apartment Market

The continuous rise in apartment rental prices is altering residential migration patterns, causing a 'post-apartment' phenomenon. Demand unable to bear the housing costs of apartments is being pushed toward non-apartment markets with relatively lower entry barriers, such as multiplexes and row houses, or to the outskirts of the metropolitan area. Indeed, since the first half of 2026, while apartment lease transaction volumes have stagnated, transaction volumes for non-apartment types have shown a marked increase.

Market Outlook and Implications

Market participants' anxiety over rising rents is also clearly confirmed by recent figures. According to a Gallup Korea survey released in early July 2026, 65% of respondents predicted that housing rents would rise further over the next year. Considering that large-scale supply is difficult to achieve in the short term, the upward pressure on prices and instability in the rental market during the second half of the year are highly likely to persist. Future changes in mortgage and jeonse loan regulations will be key variables exacerbating rental market volatility.
