Renting a property close to a Luas stop costs over €3,000 a year more than average Dublin rents.
Details from Daft.ie found that renters are paying a premium of 15% to live within one kilometre of a Luas line.
Nearly 8,000 properties were surveyed over the first nine months of this year as part of the research.
Spokesperson for Daft.ie Martin Clancy outlines the price differences: "On the Luas Green line the average monthly rent is nearly €2,300 and that's for any property on the Green line and that's a €412 monthly premium compared to the Dublin average.
"On the Red line it's a little bit cheaper overall even though the most expensive stop is on the Red line.
"The average rent on the Red line is €2,081 and that's nearly €200 more expensive per month than the average in Dublin which at the moment is €1,884."
Speaking on some of the pricier areas, Mr Clancy said: "So the most expensive stop is Spencer Dock which is right in the city centre.
"The average rent for a two or three bedroom property around Spencer Dock is €2,793.
"Then looking elsewhere, the most expensive stop on the Green line is Charlemont -again pretty much in the city centre - and that's €2,646."
