On December 17, Zhangjiakou City in Hebei issued a policy encouraging the implementation of "pre-sale housing" and gradually advancing the "cancellation of shared area"; previously, Hengyang City in Hunan clearly stated that the sale of commercial housing should be priced based on the inner building area, and currently in many places the "cancellation of shared area" has begun to be implemented. Yan Yuejin, vice president of the Shanghai E-House Real Estate Research Institute, stated that the criticism of shared area in recent years is due to the low percentage of usable area, which has affected the rights of homebuyers. The continuous release of policies indicates that the cancellation of shared area is an important task for 2025, with the usable area rate of a 100-square-meter house possibly reaching 100%, which helps improve the quality of home purchases, boosts buyer confidence, and enhances buying enthusiasm.
