Rents across the country have gone up for the third consecutive quarter, according to the latest report from property website Daft.ie.
The report, which looks at data from the first three months of the year, also says that rents are up an average of €80 a month across Dublin.
The average national rent is up 2.7% on last year's figures, and has risen for three consecutive quarters for the first time since 2007.
Rent nationwide now stands at an average of €815, compared to €794 a year ago.
Economist Ronan Lyons said the number of properties available to rent is falling and that is costing Dubliners almost a €1,000 extra over the course of a year.
He said: "It doesn't really matter which part of Dublin you look at, rents are up between four and 6%, so about 5% year-on-year for the capital as a whole.
"In some parts of the city, rents are up by 10% in two years."
