The number of properties with a value of less than 100,000 also appear to disappearing, with only a fifth of the sales (20%) in the 50,000 to 100,000 bracket. Louise Brown, one of the authors of the study, along with Professors Alistair Adair and Stanley McGreal, said it was difficult to see how the growth rate of 25% across Northern Ireland could continue. She said: "Having said that, the 25% growth in this survey is not a one-off - it's very comparable with the rates of increase during the second half of 2005. "These are boom conditions that appear to be the result of strong investment activity, relatively cheap borrowing costs and an undersupply of properties." Despite the housing boom, the average cost of a house in Northern Ireland is 30,000 lower than those south of the border.
