Sinn Féin has called on the caretaker government to intervene in the sale of NAMA residential properties to so-called "vulture funds".
It follows the decision that 200 houses in west Dublin are to be sold after the sale of a development loan.
Dublin West Sinn Féin Cllr Paul Donnelly said: "I am shocked at the massive scale of this sell off by NAMA to vulture funds so soon after the disgraceful treatment of tenants from Tyrrelstown.
"I have spent the past two weeks with shocked residents in Tyrrelstown and have demanded that this government take action to support these people who face homelessness.
"To hear from news reports that there is a selloff in the region of €5bn is just incredible, these people have no shame and only swift government action will stop this now.
"I sat and watched TD's from the caretaker government talk a lot about tenants’ rights, about social and affordable housing and how in four weeks Enda Kenny will have a new Minister for Housing to deal with this crisis, despite five years of ignoring the pleas for action.
"These properties must be investigated to ascertain how many would be suitable for social and affordable housing.
"The ball is now firmly in the hands of Fine Gael and Fianna Fáil, if they drop it now, they will not be forgiven.
"There is no more time for talk, the Dáil must be recalled and this fire sale must be stopped pending a new Government being in place".
Separately, it has been announced that 117 families on Dublin's housing list are to get new homes.
The Tuath Housing Association has been granted with funding from the Housing Finance Agency and the Department of Environment to buying new homes at An Riasc in Finglas and Thornwood in Beaumont.
