修改后The sale of our flat fell through because the buyer couldn't get a mortgage.
Didn't take place 可以传达没有发生，但 take place 更常用于音乐会、会议、婚礼等事件。这里强调房屋出售因买方贷不到款而告吹，fell through 更准确地表达安排失败的过程。
Fall through 强调计划没有实现：The deal fell through。Fall apart 则常说原本已经存在、运作的事物瓦解了，例如婚姻、团队，或者旧鞋散架：Their business fell apart after two years。

fell through — 价格已经商定，银行却在最后拒绝贷款，导致交易告吹，所以选 fell through。Fall out 可以表示争吵，如 fall out with someone，也可表示头发或牙齿掉落，不适合这里的交易。
写一个最终告吹的计划，例如旅行、搬家或购买。说明原本怎样安排，以及为什么没能实现。
Our plan to rent a cottage in Scotland fell through when the owner suddenly decided to sell it.
