the practice of unfairly demanding a reduction in the price you have agreed to pay for a house just before you buy it

In some areas of the country, gazundering is occurring in half of all house sales. 在该国的一些地区，一半的房屋销售都出现了在签合同前要求降价的现象。

While gazundering may be regarded as a questionable practice, it is legal. 虽然在签合同前要求降价可能被视为是有问题的做法，但这是合法的。
