How we compute these figures
Every number on this site is computed from official Irish data with the same open, deterministic pipeline. This page explains the sources, the adjustments we make and the limits you should know about before relying on a figure.
Data updated April 2026 · refreshed weekly from PPR, CSO and RTB.
Sources
- Property Price Register (PSRA): the record of every residential sale in Ireland. This is the base for all sale prices, medians and recent-sales lists on town pages, house prices, rental yields and the explorer.
- CSO Residential Property Price Index (tables HPM05 and HPM09): the official price index, used as a regional benchmark for year-on-year context alongside our own PPR medians.
- RTB rent data (average rents via the CSO's RIQ02 series): registered tenancy rents by town and bed size, the base for median rents and gross yields.
- Census 2022 (CSO): town population and demographic context on town pages.
- Fáilte Ireland Open Data (CC BY 4.0): the events listings behind What's on.
The VAT adjustment on new builds
The Property Price Register lists new dwellings exclusive of VAT, so a new build looks about 12% cheaper on the register than what the buyer actually paid. Before computing any median or yield we multiply new-build prices by 1.135 to add back the 13.5% VAT. This brings our medians within a few percent of the official CSO county figures. Second-hand sales are used as listed.
The 12-month median window
A town's headline price is the median of all sales in the last 12 months, VAT-adjusted as above. We use the median rather than the mean because a handful of very expensive or very cheap sales would otherwise drag the figure around. The 12-month window is wide enough to smooth seasonal noise in small towns while staying current.
The 20-sale floor on price-change rankings
On Movers, any ranking based on price change (year-on-year or 3-year growth) only includes towns with at least 20 sales in the last year. In a town with a handful of transactions, one estate launch or one large farmhouse sale can swing the median wildly, so thin markets are excluded from change rankings. Level metrics such as yield and affordability have no floor, and every town still gets its own page.
The 2% rent cap on the rent review tool
The rent review tool applies the national rent control introduced by the Residential Tenancies (Amendment) Act 2025, in force from 1 March 2026: rent increases are capped at 2% per annum or CPI, whichever is lower, applied pro-rata to the time since the last review. The tool is informational, not legal advice; the RTB is the authority on your tenancy.
Update cadence
The property dataset behind all 203 town pages and data tables is rebuilt weekly, on Mondays, from the latest PPR, CSO and RTB releases. Each data page shows the month the underlying data was last refreshed.
