Chair of the Association of Irish Mortgage Advisors is Trevor Grant, he says high prices are here to stay unless supply increases significantly:
"We fundamentally have a housing crisis in Ireland - we don't have enough houses.
"And no matter how creative everybody is in relation to assisting first-time buyers particularly to get onto the ladder with innovation on how to lend money to them, be it extending the duration of the mortgage, or lending them more in terms of an income multiple.
"There simply aren't enough houses, and until there are enough properties then we're going to see continued house price inflation."
