2H 2026 Real Estate Tax Reform and New Speculative Overheated Zones: Impact on Multiple-Home Owners
Dongtan and other key metropolitan areas are designated as Speculative Overheated Zones, blocking gap investments. We analyze the upcoming tax reforms targeting multiple-home owners and the resulting market outlook.

Introduction: A New Phase of Housing Market Regulation in 2H 2026
As the government heralds a strong policy to normalize the housing market starting in July 2026, the real estate market has entered a new phase of regulation. Tension in the market is rising as key metropolitan areas—Dongtan in Hwaseong, Giheung in Yongin, and Guri—have been newly designated as Speculative Overheated Zones and Adjustment Target Areas. This measure reflects the authorities' strong intent to control the rapid, localized price surges driven by mega-projects such as the semiconductor cluster development and the GTX transit openings.
Designation of Speculative Overheated Zones and Tighter Lending Rules
The designation of Speculative Overheated Zones, which took effect on July 1, 2026, has fundamentally altered the financing environment in these regions.
- LTV Reduction: The Loan-to-Value (LTV) ratio for non-homeowners has been drastically reduced from 70% to 40%.
- Blocking Loans for Multiple-Home Owners: For those who already own a home, new mortgage loans for the purpose of purchasing additional housing are strictly prohibited in principle, effectively halting further acquisitions.
- Land Transaction Permission Zone Effects: Starting July 5, a mandatory two-year actual residence requirement is imposed on home purchases within these areas. This is a rigorous measure designed to fundamentally block 'gap investments'—purchasing a home by leveraging the tenant's jeonse deposit.
Core Direction of Tax Reform for Multiple-Home Owners
Along with the zoning designations, market attention is heavily focused on the real estate tax reform plan scheduled to be announced later in July. This reform is aimed at increasing the tax burden on multiple-home owners and restructuring the tax system to favor actual end-users.
1. Heavy Taxation on Acquisition and Capital Gains
Acquiring two or more homes within regulated areas will trigger progressive and heavy acquisition tax rates. Furthermore, the exemption from heavy capital gains taxes upon selling properties will be abolished. This will act as a primary factor pressuring multiple-home owners to restructure their asset portfolios.
2. Stricter Residence Requirements for Long-Term Holding Deductions
The special deduction for long-term holding, which was previously granted based primarily on the holding period, will be restructured to focus on actual residence requirements. This means that tax benefits for investment properties that were held long-term without actual occupancy are highly likely to be significantly reduced.
3. Realizing Holding Taxes via Adjustment of the Fair Market Value Ratio
Rather than direct nominal tax rate hikes, an upward adjustment of the fair market value ratio is being strongly discussed as a way to gradually increase the effective burden of property taxes and the comprehensive real estate holding tax. This aims to lower the expected return on real estate assets, thereby inducing multiple-home owners to release their properties onto the market.
Market Outlook and Implications
As tighter lending regulations and tax reforms intertwine, the metropolitan real estate market in the second half of 2026 is expected to see a clear decline in transaction volumes and a strong wait-and-see approach regarding prices. With rising financing costs and actual residence mandates, demand seeking short-term capital gains is bound to plummet.
Multiple-home owners and wealthy individuals must urgently adopt strategies to optimize their portfolios, such as proactively selling off low-yielding assets in consideration of the increased holding tax burdens and heavy capital gains taxes. Conversely, for end-users with strong cash flow generation capabilities, this could present an opportunity to enter prime locations where price momentum has cooled due to regulations; however, establishing a conservative financing plan capable of handling the lowered LTV limits is absolutely essential.
