Foreign funds convert Seoul officetels as monthly rent takes 68.3% of Korean leases

The number a corporate landlord actually underwrites is 61.8%, which is what the monthly-rent share was a year before it reached 68.3% of Korean residential lease transactions in the first seven months of this year ^[1][1], and at 6.5 points a year the nationwide figure meets the 80.4% already recorded in non-apartment housing in about 1.9 years ^[2][2]. Within that non-apartment stock the split is worth reading twice: 78% in Seoul against 87.5% outside the capital region ^[2], so the conversion is furthest advanced in the buildings cross-border capital is not buying.

Where the income shows up is co-living, which JLL Korea prices at a median 1.13 million won a month for Seoul units of 40 square meters or less against 790,000 won for a conventional officetel ^[6]. That gap is 340,000 won a month, or about 4.08 million won a year per unit ^[3], and it buys the tenant shared lounges, amenities and community services that somebody has to staff ^[7]. Cushman's respondents ranked co-living second among preferred residential asset types ^[8]. JLL counts at least 17 major rental housing and co-living deals in Korea since the start of 2024 ^[10]; Morgan Stanley's three officetels (Doksan-dong in 2024, then Gil-dong and Anam-dong) ^[11] and KKR's Yangpyeong-dong residence building ^[13] came out of that pipeline, while Canada Pension Plan Investment Board has taken the other route, build-to-rent with the domestic operator Mangrove ^[12]. None of the prices appear in these sources, so the 4.08 million won cannot be turned into a yield here.

Scale is the other soft spot. The $33.2 billion expected over five years ^[5], set against the roughly 224,000 units the respondents already manage ^[4], is about $148,000 per unit of existing book ^[4], which is an increment to a portfolio rather than a doubling of it, and the 85% who say they will raise residential allocation ^[4] are stating intent in a survey where Korea placed behind Australia and New Zealand, Japan and Singapore ^[3].

The causal story in the reporting is that jeonse fraud, disputes over unreturned deposits and high interest rates pushed tenants toward monthly rent ^[14]. Two of those are memory and litigation, which do not reverse quickly; the third is a rate cycle, which does. The durable half of the case is demographic: about 41% of households are single-person, and half of a 51.1 million population lives in the greater Seoul area, Seoul alone holding about 18% ^[15], and none of that moves with the policy rate. So the view, or rather the version worth holding, is that Korea's rent roll is real but early, and what would break it is a Ministry of Land print showing the monthly share flat near 70% while jeonse borrowing gets cheaper, because that would date the conversion to funding costs rather than to a change in what tenants want.
