有一种难受叫买了“复式楼”，不好住、不好卖，彻底沦为不动产

Core Viewpoint - The popularity of duplex apartments has significantly declined, transforming from a sought-after property type to one that is difficult to sell and live in, primarily due to various inherent disadvantages [1][3][21]. Group 1: Advantages of Duplex Apartments - Duplex apartments were initially favored for their ability to maximize living space, allowing for a more spacious feel compared to traditional flats [3][5]. - They offer distinct areas for socializing and privacy, making them suitable for families with multiple generations [5][7]. - The design allows for multiple bedrooms and bathrooms, catering to larger families and enhancing convenience during peak hours [7][9]. Group 2: Disadvantages of Duplex Apartments - Poor sound insulation is a significant drawback, leading to disturbances between floors, which can negatively impact the living experience [9][11]. - The actual living space can feel cramped, with limited airflow and natural light, affecting overall comfort and health [11][13]. - The installation of stairs can be inconvenient and poses safety risks, especially in smaller spaces [13][15]. - High renovation costs are associated with duplex apartments, often exceeding 500,000 yuan for a 150 square meter unit, making them less accessible for average families [15][17]. - Living costs can be elevated, particularly for apartment-style duplexes, due to commercial rates for utilities and restrictions on cooking methods [17][19]. - Many duplex apartments lack property certificates and have shorter ownership terms, which can deter potential buyers [19][21]. - The current real estate market is sluggish, leading to poor liquidity for duplex apartments, with many owners facing losses when trying to sell [21].
