South Korea is reviewing Comprehensive Real Estate Tax relief to expand corporate rental housing as Seoul faces a sharp contraction in new supply and record monthly rent burdens. The Ministry of Land, Infrastructure and Transport is considering tax benefits for corporations that buy newly built homes and lease them for at least 20 years, including aggregation exclusions in designated adjustment zones and a 300 million won increase in the assessed-value threshold for qualifying rental housing in non-adjustment zones. Seoul's new construction-type rental supply fell 81% from 21,115 units in 2021 to 3,976 in 2024, while the national rental stock remained near 3.3 million units for five years from 2020. Seoul's multi-family monthly rent index increased 3.25% from January to July this year, more than twice last year's comparable rise. Average July rent for studios of 33 square meters or less was 690,000 won on a 10 million won deposit, rising to 970,000 won in Gangnam-gu; total costs exceeded 1 million won after fees and utilities. Households headed by people aged 39 or younger saw nominal monthly income fall 1.7% year over year while housing expenditure rose 11.6%. The government wants to shift private rentals from individual multi-homeowners toward corporations and REITs (real estate investment trusts), alongside public entities, but industry participants say tax relief alone will not overcome high land, project and financing costs. Separate youth measures include relaxed monthly rent support, larger public rental homes near transit hubs, equity-accumulation and profit-sharing sales, and a preferential-rate Youth Future Bogeumjari Loan for first-time buyers of non-apartment homes priced at 400 million won or less.
