The Dáil will later debate a Sinn Fein motion calling for the Government's new shared equity plan for housing to be scrapped.
It would see the State cover up to 30 percent of the cost of a new home in exchange for a stake.
The Housing Minister Darragh O'Brien says it'll help thousands stuck in an affordability gap, but the opposition think the focus should be on delivering more affordable homes.
Mayo Sinn Fein TD Rose Conway-Walsh insists the FF developer scheme will push up house prices, and is calling on Government to invest instead in real affordable homes to rent and buy.
She claims the ESRI, Central Bank and Institute of Professional Auctioneers and Valuers all have concerns that this plan may increase the price of homes, and says a group of FG Councillors also wrote to the Minister asking him to scrap the scheme, as it risked a return to failed housing policies of the Celtic Tiger era.
