Core Viewpoint - The second-hand housing transaction scale has slowed down since the second quarter of 2025, but the cumulative year-on-year growth is significantly better than that of new homes, remaining in a high-level fluctuation market [3][13]. Group 1: Transaction Volume and Structure - In the first half of 2025, the cumulative year-on-year growth of second-hand housing transactions in 30 key cities was 12%, contrasting sharply with the new housing market [3]. - The demand for luxury homes priced above 30 million in Beijing, Shanghai, and Shenzhen remains stable, while the transaction proportion for homes priced between 3-6 million has significantly declined, indicating increased buyer hesitation [4][5]. - The ultra-low price segment (under 2 million) shows a serious downgrade in consumption among extreme first-time buyers, with transaction concentration in low-priced properties in Shanghai, Shenzhen, and Hangzhou continuing to rise [5]. Group 2: Area and Size of Transactions - The transaction concentration for small-sized properties (under 90 square meters) has decreased, while the proportion of transactions for larger properties (over 140 square meters) has increased, driven by the demand for more functional living spaces [6][7]. - In major cities, the transaction concentration is shifting towards medium-value areas, with notable declines in transaction concentration in primary areas of Shanghai and Shenzhen [10][11]. Group 3: Market Outlook - The second-hand housing market in Beijing, Shanghai, Shenzhen, and Hangzhou is expected to continue a stable but declining trend in the short term, influenced by new listings and the quality of new housing products entering the market [13]. - The current market is transitioning to a buyer's market, where buyers are increasingly considering location, amenities, and price, leading to longer transaction cycles for older properties in less desirable areas [13].
