A leading housing charity has accused landlords of "downright extortion" for hitting tenants with massive rent hikes.
Senator Aideen Hayden, chairperson of Threshold, made the comments at the Generation Rent conference in Dublin.
The conference heard of the problems in the rental market from various stakeholders including homeless charities and academics, as well as Environment Minister Alan Kelly.
Ms Hayden said "rent certainty" needed to be brought to the market immediately to protect renters and said rent hikes of 50pc were forcing families into homelessness.
She said it was "downright extortion" when landlords hit renters with hikes in cases where the house has been paid off and the owner is not dependent on the money to pay a mortgage.
She said that landlords would also benefit from some rent certainty.
