Minister for Housing Eoghan Murphy has said if the housing crisis is to be addressed then the focus has to be on increasing supply.
A new survey from MyHome.ie and Davy shows house prices are continuing to rise, with the average asking price nationally now at over €250,000.
Minister Murphy said more houses have to be built and the more availability there is, the greater the affordability.
Speaking at a conference on social housing, he said the focus should be on the supply of houses if the homeless crisis and the continuing rise in house prices are to be addressed.
The minister said the Help-to-Buy scheme is under review and he is not making any decisions or recommendations until that is completed.
However, he said he is looking at ways of expanding the Mortgage-to-Rent scheme.
He said the scheme has a lot of capacity in terms of eligibility and wants to see if more can be done.
