Donegal has among the lowest average rents in the country, concentrated in Letterkenny, Buncrana and Ballybofey. Supply outside these towns is very limited. Older rural stock can mean solid-fuel heating and poor BER ratings — factor winter energy costs into your budget.
Since 1 March 2026, a national rent control system applies across Ireland, including Donegal. Rent increases are capped at the lower of 2% per year or the general rate of inflation, and rent may be reviewed once every 12 months.
