Top developments

Vietnam enforces major property regulation change from September 1

Effective September 1, 2026, Vietnam introduced a significant regulatory change affecting the real estate sector, drawing attention from millions of citizens. While specific technical details of the "major change" are highlighted as a key focus for local buyers and investors, this move comes amid broader efforts to clarify legal frameworks and market transparency. This follows recent data from the Ministry of Construction indicating that secondary market apartment prices in Hanoi averaged VND 123 million/m² in Q2, showing a decline compared to Q1, which suggests the new rules aim to stabilize a cooling high-end segment.

Thailand probes 36,000+ foreign entities for land ownership violations

The Thai Department of Business Development (DBD) has identified 36,277 foreign legal entities holding land titles across the country, with Chonburi province ranking highest in concentration. Authorities are now investigating potential "nominee" arrangements where foreigners use Thai nationals to bypass ownership restrictions, particularly in popular tourist and residential hubs. This crackdown targets long-standing issues in the sector, aiming to enforce the 49% foreign ownership quota in condominiums and prevent illegal land holding through corporate structures.

Singapore prime home prices grow 0.4% in 1H2026, Savills predicts stronger H2

Savills reported that Singapore’s prime residential capital values grew by just 0.4% in the first half of 2026, but projects stronger growth in the second half. The firm forecasts Singapore, along with Seoul and Kuala Lumpur, to lead Asia-Pacific prime residential growth, driven by rental yields rising four times faster than prices. This aligns with URA data showing private residential prices rose 0.5% quarter-on-quarter in Q2 2026, a slowdown from the 0.9% increase in Q1.

Sydney property values drop 7.1% from February 2026 peak

Recent data indicates that Sydney house and apartment prices have declined by 7.1% from their peak in February 2026, despite a 5.6% increase over the past five years. The correction reflects a gradual weakening in the market throughout the year, with Melbourne gaining momentum while Perth has seen declining momentum over the last two years.

Local view

Thailand: Local media outlets like Thairath and The Standard are focusing heavily on the government's aggressive stance against foreign nominee structures. The narrative emphasizes that while foreign investment is welcome, the era of lax enforcement on corporate land-holding vehicles is ending, with Chonburi and Bangkok being primary targets for audits.

Vietnam: Vietnamese press, including Thanh Nien and CafeF, highlights the dual narrative of price corrections in Hanoi apartments and the new regulatory framework effective September 1. Stakeholders are watching how these rules will impact liquidity and whether they will successfully curb speculative behavior without stifling legitimate demand.

Context & numbers

• Vietnam: Hanoi secondary market apartment prices averaged VND 123 million/m² in Q2 2026; Ho Chi Minh City averaged VND 108 million/m².
• Thailand: Foreign buyers accounted for 32% of central Bangkok condominium purchases, rising to 67% in Bang Tao and Cherng Talay (Phuket) according to CBRE.
• Singapore: Private residential price index rose 0.5% QoQ in Q2 2026; CCR (Core Central Region) surged 2.0%, while RCR (Rest of Central Region) fell 1.4%.
• Australia: Sydney property values are 7.1% below their February 2026 peak.

On the radar

• Vietnam Implementation: Monitor immediate market reaction and compliance reports following the September 1 regulatory change.
• Thai Nominee Audits: Expect further announcements from the DBD regarding specific companies or individuals found violating foreign ownership laws in the coming weeks.
