买房选楼层太高太低都不好，内行人专挑这几层，原来好处多多！

Core Viewpoint - Selecting the right floor in a property is crucial for a satisfactory living experience, balancing factors such as noise, light, and comfort. Group 1: Golden Rules for Floor Selection - The first rule is the Golden Section Rule, which suggests choosing a floor located in the upper-middle part of the building, calculated by dividing the total number of floors by two and adding one. This position helps mitigate noise from lower floors and improves light conditions while avoiding excessive dust from higher floors [5][6]. - The second rule is the One-Third to Two-Thirds Rule, recommending floors that are above one-third but below two-thirds of the total floors. These floors typically offer good light and air circulation while avoiding the dampness associated with lower floors [6]. Group 2: Cautionary Considerations - Caution is advised regarding ground-level (or elevated) floors, as they may lack support from lower units, leading to discomfort from cold drafts [8]. - The top floor should be approached with care due to potential water leakage issues. If the property management is unresponsive, residents may face significant inconveniences [11]. - Attention should also be given to mid-level floors, as they often have smaller window areas, which can negatively impact indoor lighting, and may be prone to water accumulation if waterproofing is inadequate [13].
