Meanwhile, as the property market soars an investigation has been ordered into dubious practices among estate agents. The inquiry, into profiteering and corruption, will be conducted by the Office of Fair Trading. Prompted by a record number of complaints, the investigation is likely to examine gazumping, a legal but widely despised ruse in which a house seller in a rising market increases the asking price after acquiring a buyer. Estate agents usually act as middle men in gazumping and profit from the higher prices.
