根据你的要求查询相关周围的房子成交价格是什么
正如icky用的是buying price，我们不需要去看太多cov，只要重视最终你的成交价格。当然再贷款上稍微有些却别。
如果房东把房子拿出来卖，他也想快点成交，因为如果已经买新房子的人也需要卖掉的钱快点入CPF,如果还没有买房子的人也害怕他要去的买的房子会涨价，所以如果通常只有一套房子的房东，他们普遍会采取的方法就是已经找到了新的房源，签了OTP (option to purchase)然后开始积极的卖房子。但是这个绝对不是你可以用来和房东讨价还价的资本，因为现在至少今年初到现在还是一个卖家市场，你只要觉得价格合理，房子满意就好了，房东也不会说新的valuation report估价比上一个得贵了2万，然后他就在cov不变的基础的再加你2万，这样他也很难卖掉。
http://www.hdb.gov.sg/bb33/ispm051p.nsf/Search 上的数据都是 1st appointment 过后确定了买卖关系，买家交了前过后的数据，所以其实比OTP确定买卖意愿和成交价慢了1-2个月左右。但是还是非常具有参考价值的。
