别再被忽悠！真正不能买的，不是4楼14楼，而是这“5个”楼层！

Core Viewpoint - The article emphasizes the importance of carefully selecting floors when purchasing a property, highlighting five specific types of floors that should be avoided despite their potentially lower prices [1]. Group 1: Types of Floors to Avoid - Top Floor without Terrace: The top floor can lead to extreme temperature variations, resulting in significantly higher energy costs, potentially doubling monthly electricity bills compared to other floors [5]. - Floors Adjacent to Garage: These floors are subject to constant noise from vehicles, which can severely disrupt sleep quality and overall health [6]. - Floors Next to Equipment Rooms: Proximity to equipment rooms can expose residents to continuous noise and vibrations from machinery, negatively impacting mental focus and health [7]. Group 2: Additional Concerns - Waistline Floors: Decorative waistline designs can obstruct light and ventilation, leading to damp and dark living conditions, while also accumulating dust and bacteria that pose health risks [9]. - Second Floor (Flooding Risk): The second floor often bears the burden of the building's drainage system. Without independent drainage, issues can lead to unpleasant sewage backflow, compromising living conditions and health [13].
