The average price of new houses in Derry has fallen by almost 25% in the last quarter of last year, according to figures released by the Department of Social Development.
The Department found the average price to be £170,900 between July and September 2012.
But that figure fell to £132,600 in the last quarter, October to December, of last year according the the DSD’s figures.
The same research has found that 32 new houses were sold in Derry in the last six months of 2012.
Across the north, the average selling price of National House Building Council (NHBC)-registered new houses sold was £147,700, a decrease of £18,800 (11.3%) on the same quarter in 2010.
The average selling price of NHBC-registered new houses ranged from £99,300 in Larne Local Government District to £192,100 in Fermanagh Local Government District.
The data for new house sales and prices is derived from transactions for new dwellings notified by solicitors to the National House Building Council (NHBC).
While NHBC-registered builders account for a very high proportion of newly-built dwellings, their coverage is less comprehensive in rural areas.
The figures were taken from the Northern Ireland Housing Bulletin.
