The average price of a home in Northern Ireland has risen by 25% - or £600 a week - in the past year.
Northern Ireland's house prices rose by £600 a week
The latest quarterly house price index, compiled by the University of Ulster, showed the average price of a home has hit £153,000, £31,000 more than 2005.
The report concluded the rise of 25% is unlikely to be sustained.
However, it also points out that the average house price in the province is still £30,000 lower than the rest of the UK and the Republic of Ireland.
It also highlights the fact that the number of houses costing below £100,000 is shrinking fast.
Lisburn saw an unprecedented rate of growth of 44% to an average house price of just over £188,000 while overall, the highest priced city location is south Belfast, with an average of £188,069.
In Belfast, the overall average price of £145,051 is up by 23.6% over a year.
East Belfast with an overall average price of £165,432 is the next highest; the average price in west Belfast is £113,052, while the north Belfast average is £107,673.
The authors of the survey Professor Alastair Adair, Professor Stanley McGreal and Louise Brown said it was unlikely that growth rates of 25% a year could be sustained.
Mrs Brown said undersupply was a factor in the high growth in prices.
"It's hard to see how this rate of increase can go on," 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."
