The latest Daft.ie report shows rents have risen by 10 per cent in the past year nationally, to an average of more than 1,500 euro.
In Cork city rents are up over 6% now averaging 1529 euro a month, while they have jumped over 10% in the county and now stand at 1217 euro
The number of available properties to rent in Cork still remains at record lows with just 107 available on Daft in the county and 44 in the city this morning.
Housing expert Rory Hearne, who's a professor of social policy at Maynooth University, says there should be a freeze on rents:
"You can actually control the rents and the RPZs show that, now they are having a limited impact, but they are at some level, the rent caps are controlling them. So I would actually argue that the rent and pressure zones should be extended across the country. That is vital. Also, I do believe there should be a freeze rather than a 2% cap on rents."
