📊 Regional Supply Trends

Seoul Metropolitan Area (Seoul, Gyeonggi, Incheon)

Seoul apartment prices posted a weekly gain of 0.31% in mid-May, marking the year's strongest weekly appreciation. What's notable: this week's rally was led by non-Gangnam districts like Seongbuk and Seodaemun, not the traditional Gangnam trio. Since Seoul's land transaction approval zone took full effect, some areas show cautious trading, but reconstruction-focused complexes are driving active transactions, according to MK reporting.

In Gyeonggi Province, over 11,000 Seoul residents purchased apartments between February and April. With Seoul now entirely subject to land transaction restrictions, demand is rapidly spilling into Gyeonggi, where regulations are relatively looser. Buyers are particularly concentrated on heavily discounted inventory, analysts note.

In Incheon's Songdo, The Sharp Songdo Grand Terre by POSCO E&C began sales in week 3 of May. Anticipation around GTX-B line benefits has captured real buyer interest.

In Osan, Gyeonggi, GS E&C announced a mega-complex of 1,517 units for June launch. Osan's improved transit infrastructure—SRT and express buses—is attracting metro-area real buyers.

Five Major Metropolitan Cities (Busan, Daegu, Gwangju, Daejeon, Ulsan)

Busan is set to see SK Eco Plant launch a premium complex in June. As part of the four-complex premium lineup (3,294 units), demand for brand apartments in Busan's prime locations is expected to follow.

In Gyeongsan, North Gyeongbuk, Kumkang Housing and IS Dong-Seo are preparing for a June launch. Gyeongsan's proximity to Daegu's city center positions it well to capture Daegu-area buyers.

Secondary Cities Nationwide

As of this week's data, verified recent supply schedules for major mid-tier cities—Sejong, Cheongju, Cheonan—have not been confirmed.

📜 Policy & Regulatory Updates

① Seoul-wide land transaction approval zone remains in effect: With all of Seoul now subject to transaction restrictions, some areas face tightened trading conditions. This has accelerated real buyer migration to Gyeonggi and Incheon, fueling increased subscription demand for Gyeonggi complexes.

② Home-loan-to-value (LTV) tightening: Mortgages on properties over 1.5 billion won in regulated zones and Seoul have been capped at 200–400 million won (down from 600 million won previously). High-end apartment buyers face direct financing pressure and must plan carefully.

③ President Lee Jae-myung's housing stability agenda: President Lee has flagged housing costs as a threat to national viability and made residential stability a core policy pillar. A dual approach—supply expansion plus speculation controls—is shaping market dynamics.

💹 Real Estate Market Metrics

National home sale price index trend: Seoul apartment weekly gain of 0.31% (week 3 of May, the year's best weekly performance). Non-Gangnam-led rally.
Metro-area jeonse index: Seoul apartment jeonse (lease deposit) prices continue climbing. Tight jeonse inventory and stabilized rates sustain demand. For precise weekly index figures, check the Korea Real Estate Board's R-ONE portal (r-one.co.kr).
Unsold inventory nationwide: This week's latest official tally is pending Korea Real Estate Board release. Check R-ONE (r-one.co.kr) for confirmed figures.
Benchmark rate & mortgage rates: Current mortgage conditions combined with LTV caps (600 million → 200–400 million won for properties over 1.5 billion on regulated/Seoul properties) have increased funding pressure on high-end complex buyers.

🧭 Subscription Checklist for Buyers

Manage subscription points: Three core elements—months of non-ownership, dependents, and subscription account tenure—drive point scoring. Keep your subscription account contributions consistent (1 deposit per month recognized; 100,000 won+ monthly recommended), maximize your non-ownership period, and update family changes (birth, marriage, etc.) immediately—each boosts your score. Family growth is a point opportunity.
Capital planning: With LTV caps now at 4 billion won maximum for properties over 1.5 billion in regulated/Seoul zones, you'll need higher equity. Identify your deposit schedule upfront (typically 10–20% of sale price), progress payment timing (40–60%), and final payment (20–30%), and size total borrowing to stay under DTI (debt-to-income ratio) thresholds.
Location assessment: ① GTX-A, B, C metro line coverage—Osan, Songdo, Wangsuk and other GTX-beneficiary suburbs are key upside drivers for peripheral complexes. ② School district strength—especially for new towns and designated zones; verify planned school opening dates. ③ Development pipelines—complexes near industrial parks or mixed-use projects can see future appreciation, but verify feasibility.
Risk warnings: Non-Gangnam Seoul and select Gyeonggi areas are showing short-term buying frenzies, raising overvalued sale-price risk. Seoul's land transaction restrictions create liquidity constraints, and delayed delivery (2–3 years post-purchase) introduces post-completion price-decline exposure. Monitor political and policy shifts (post-June 3 local elections may bring real estate policy adjustments).
