Average rent in Castletroy

What this figure is, and what it is not

It is the average rent on tenancies in Castletroy that were registered with the Residential Tenancies Board, which every landlord is required to do. It is an average rather than a median, so a small number of expensive lettings pull it upwards.

It is not the rent being asked in advertisements. An asking rent is what a landlord hopes for and this is what was signed.

It is not what a sitting tenant is likely to be paying either. A tenancy enters this average at the rent agreed when it started and does not enter again, so the figure leans towards recently agreed rents and sits above what somebody who has been in the same home for years pays.

If your own rent is going up, the figure that governs it is not this one. What a landlord may lawfully charge is worked out from the rules and your own history, and the rent increase calculator does that with the figures shown.

Buying instead of renting in Castletroy

A sale median and a rent average are two different statistics about two different sets of homes. Neither one converts into the other and nothing on this site treats them as though it did.

Where this comes from

The quarterly and annual average monthly rent tables published by the Residential Tenancies Board, via the Central Statistics Office, used under the Creative Commons Attribution 4.0 licence. Imported 9 September 2026. The yearly figures come from the annual table rather than from averaging the quarters, because averaging four averages would produce a figure the Board never published.
