“公摊”是指商品房买卖过程中，购房者除了自家套内使用面积外，还需要分摊公共区域的建筑面积，如楼梯间、电梯井、走廊、公共大厅等。
公摊的英文意思是：Shared/common area 或 shared/common space allocation。
公摊面积 是指建筑物中由业主共同占有和使用的公共部分所占的建筑面积。Common area 指楼宇中为住户共同使用的区域；而 shared space allocation 更具体地指购房者分摊的这部分面积。
两个英文表达概念：
公摊面积包括楼梯间、电梯间、走廊等。
The common area includes staircases, elevator shafts, and corridors.
公摊面积的比例直接影响房屋的得房率。
The proportion of shared space directly affects the net usable area of a property.
得房率（Net Usable Area Ratio）
得房率是指套内建筑面积（net usable area）与房屋建筑总面积的比例。即：得房率 = 套内面积 ÷（套内面积 + 公摊面积）× 100%。
以下是与购房相关的英语表达，涵盖公摊、房贷、利率等常见话题：
房屋面积与公摊
套内建筑面积（Net usable area）: The area that the homeowner can actually use.
建筑面积（Gross floor area）: The total area of the property, including shared spaces.
得房率（Net usable area ratio）: The percentage of net usable area to the gross floor area.
购房与房贷
首付（Down payment）: The initial payment made when buying a property.
房贷（Mortgage loan）: A loan taken to finance the purchase of a property.
贷款利率（Loan interest rate）: The percentage charged on a mortgage.
按揭还款（Mortgage repayment）: Regular payments made to repay the loan.
购房费用与税费
契税（Deed tax）: A tax paid when a property is transferred.
物业管理费（Property management fee）: A fee for maintaining shared spaces in a residential building.
了解公摊面积
Buyer: What’s the ratio of the net usable area to the gross floor area for this apartment? 买家：这套房子的得房率是多少？
Agent: The net usable area ratio is approximately 80%, which means the shared space accounts for 20% of the total area. 经纪人：得房率约为80%，公摊面积占总面积的20%。
讨论贷款与利率
Buyer: I’m considering a mortgage loan. What’s the current interest rate? 买家：我正在考虑房贷，目前的贷款利率是多少？
Bank Representative: The interest rate for a 30-year fixed mortgage is 5.5%. 银行代表：30年固定房贷利率是5.5%。
购房预算讨论
Buyer: If the property price is $300,000 and the down payment is 20%, how much will I need for the initial payment。 买家：如果房价是30万美元，首付比例是20%，那我需要多少首付款？
Agent: You’ll need $60,000 as a down payment, and the rest can be financed through a mortgage. 经纪人：你需要6万美元作为首付，其余部分可以通过房贷支付。
那么问题来了，你觉得取消公摊是否会带来更高的购房性价比？
