Rents in Co Mayo in the first quarter of this year were almost 20% higher than in the same period last year- reflecting very low availability.
That's according to the latest rent report from property website Daft.ie
The average listed rent in Mayo is now €955 per month - compared to the national average of over €1500.
In Galway city, rents rose by over 13% to €1,585 per month.
The report says rental homes have become very scarce, and policymakers must focus on creating the conditions for tens of thousands of new rental homes to be built over the coming years.
