Phantom offer is a nonexistent offer to purchase a house, used to coerce people making real offers into raising their prices. 

“幽灵出价”指的是购房时并不存在的买方出价，目的是迫使人们做出真实出价，抬高房价。

Your below-asking-price offer has been accepted, the property you are buying is off the market, and it's all steam ahead towards completion. Then the next week, the Estate Agent calls to say that someone who viewed the property previously has put in an offer a few thousand pounds above yours.

你最初的出价低于卖方的要价，卖方也接受了。你要买的这套房下架，你就要买成了。紧接着，下一周，房产中介就给你打电话，说之前看过房的某位客户出价比你多了数千英镑。
