Core Insights - The increasing interest in old residential buildings, particularly top floors in first and second-tier cities, is driven by their high investment return potential and relatively low risk [1][3][6]. Investment Opportunities - High Return on Investment: Investors are attracted to the high rental yields from old properties, exemplified by a 35 square meter unit in Shanghai purchased for 1.8 million yuan, generating a monthly rent of 4,000 yuan, leading to an annual rental income of 48,000 yuan, which significantly exceeds bank deposit rates [3]. - Potential for Wealth through Renovation and Demolition: The prospect of substantial returns from property renovation or government-led demolition is a major draw. For instance, a 33 square meter top-floor unit bought for 1.8 million yuan could yield compensation exceeding 5 million yuan upon demolition, offering multiple times the initial investment [6]. - Hidden Value of School Districts: Many old residential areas are located in city centers near prestigious schools, providing potential for appreciation in property value. The lower prices of top-floor units create greater upside potential in a society that increasingly values quality education [7]. Risks and Challenges - Investment in old residential buildings carries inherent risks, including uncertainty regarding renovation and demolition prospects. Not all old properties will be favored by government initiatives, and their price resilience is relatively weak, making them susceptible to market fluctuations [9].
