New figures show that the average house price fell by more than €20,000 in the first six months of this year.
The house price index, compiled by Permanent TSB and the ESRI, fell by 1.5% in June, bringing the drop over the previous 12 months to 11.7%.
In the first six months of the year, house prices fell by 7.7%, bringing the average price in June to €241,504. The figure was €261,573 at the end of December last year.
Permanent TSB said the June figure confirmed the pattern of recent months, as poor demand and oversupply cancelled out the benefits of lower interest rates.

The survey is based on the agreed sale price and is calculated using figures from mortgage drawdowns. The index is a three-month moving average. The compilers point out that there may be a time lag between the time the sale price is agreed and when the mortgage is drawn down.
