Core Viewpoint - The article discusses the misconception that residential properties will become unsafe or uninhabitable after 20 or 30 years, emphasizing that modern buildings typically have a lifespan of at least 50 years and often much longer [1][2]. Group 1: Lifespan of Properties - Modern residential buildings are generally designed for a lifespan of 50 years, with many high-quality constructions lasting even longer [1]. - Examples of properties over 20 years old, such as the Happiness Coast in Bao'an and the Kingkey Financial Center in Luohu, demonstrate that they have not become unsafe and still maintain high market values, with prices around 80,000 to 92,000 yuan per square meter [2][5]. Group 2: Importance of Enjoying the Present - The article suggests that purchasing a home should be viewed as an opportunity to enjoy a better living environment now, rather than worrying excessively about future property status [5][6]. - The unpredictability of future conditions makes it unreasonable to delay home purchases based on long-term concerns about property safety [5]. Group 3: Maintenance and Management - Regular maintenance by professional property management can significantly extend the lifespan of buildings, preventing them from becoming unsafe [8]. - While aging properties may face issues, the likelihood of a building becoming uninhabitable after 20 years is considered very low, especially with proper upkeep [8].
