South Korea Implements Massive Real Estate Clampdown: All of Seoul Now a Land Transaction Permit Zone

In a sweeping effort to stabilize an overheating housing market, the South Korean government has implemented some of the strictest real estate restrictions in the nation’s history. Under the “October 15 Measures,” the government designated the entirety of Seoul and 12 key areas in Gyeonggi Province as Land Transaction Permit Zones, effectively placing a tight leash on property transfers to curb escalating prices.

Understanding the 10·15 Housing Stabilization Measures

Announced on October 15, 2025, following a joint-ministry meeting, the government’s novel policy is a preemptive strike against rising home prices and a surge in sales transactions. The measures expand the designation of regulated areas—previously limited to Yongsan-gu and the three Gangnam districts (Gangnam-gu, Seocho-gu, and Songpa-gu)—to encompass the entire Seoul metropolitan area.

These regions are now classified under three restrictive categories: Land Transaction Permit Zones, Speculative Overheating Zones, and Areas Subject to Adjustment. The designation of Land Transaction Permit Zones, considered the toughest restriction under Korean real estate law, took effect on October 20, 2025, and is scheduled to remain in place through December 31, 2026 [1].

Geographic Scope of the Regulations

The clampdown isn’t limited to the capital. While all 25 districts of Seoul are now regulated, the government has also targeted 12 specific areas in Gyeonggi Province to prevent price hikes from spilling over into the suburbs [2].

Regulated Areas in Gyeonggi Province:

• Gwacheon and Gwangmyeong
• Seongnam: Bundang, Sujeong, and Jungwon Districts
• Suwon: Yeongtong, Jangan, and Paldal Districts
• Anyang: Dongan District
• Yongin: Suji District
• Uiwang and Hanam [3]

Financial Restrictions and Loan Caps

To stifle demand, the government has significantly tightened borrowing rules. The most impactful change is the reduction of the loan-to-value (LTV) ratio. For individuals who do not own a home, as well as single-home owners who agree to sell their existing property, the LTV ratio has been slashed from 70% to 40% [2].

These tightened loan caps, combined with residency requirements for those purchasing land in permit zones, are designed to block speculative investors from relocating capital into Seoul’s residential market.

Political Context and Local Backlash

This policy marks the third major housing intervention by the Lee Jae Myung administration, following lending restrictions on June 27 and a housing supply plan on September 7 [3]. The administration has moved toward these “drastic measures” after previous attempts failed to rein in price surges.

However, the move has met significant resistance. On October 22, 2025, the Seoul Metropolitan Council of District Mayors, led by Songpa District Mayor Seo Gangseok, issued a joint statement demanding the withdrawal of the measures [4]. Fifteen district mayors from opposition parties argued that the unilateral regulations infringe upon the property rights of residents and distort the housing market rather than stabilizing it.

Frequently Asked Questions

What is a Land Transaction Permit Zone?

It is the toughest restriction available under Korean real estate law, requiring buyers and sellers to obtain a permit from the government to complete a transaction, often involving strict residency requirements to ensure the buyer intends to actually live in the property.

Which Gyeonggi cities are affected?

Affected areas include Gwacheon, Gwangmyeong, Hanam, Uiwang, and specific districts within Seongnam, Suwon, Anyang, and Yongin.

How does the LTV change affect me?

If you are a first-time buyer or a single-home owner planning to sell, you can now only borrow up to 40% of the property’s value, compared to the previous 70% limit.

Conclusion

The 10·15 policy represents a high-stakes gamble by the South Korean government to halt a runaway real estate market. By combining strict permit requirements with aggressive loan caps, the administration is attempting to decouple housing from speculative investment. However, with strong opposition from local district mayors and concerns over property rights, the long-term efficacy and political sustainability of these measures remain to be seen.
