Chief economist with Davy, Conall Mac Coille, said residential property price inflation was now back in double-digit territory for the first time in two years.
“Ireland’s strong economic recovery, the lack of housing supply, the introduction of the Help to Buy scheme, and the loosening of the Central Bank mortgage rules are the likely factors driving the acceleration in house price inflation,” said Mr Mac Coille.
Chief economist with Merrion Capital, Alan McQuaid said there was a housing crisis and, until politicians got their act together, prices would continue to rise.
“In our view, we need some radical thinking on this. We need to start treating houses solely as a place to live and not as an investment asset.
“Government policies, tax or otherwise, need to be geared towards favouring those wanting the house to live in over those who are buying purely for investment purposes.”
