Questions
What is the average house price in Portmarnock?
The median price paid in Portmarnock over the last 12 months was €730,000, based on 118 sales filed in the Property Price Register. Across the full year 2025 the median was €727,500, +8% on 2024.
How many houses have sold in Portmarnock?
1,615 sales since January 2010. About 31% were new builds. Sales marked "nfmp" were not at full market price (for example a transfer between family members) and are left out of the medians.
Why are some pins in the middle of the estate?
Eircodes were only added to the register around 2021. For earlier sales we place the pin at the centre of the estate or street, calculated from newer sales with an Eircode on the same road. 1,399 of 1,615 sales in Portmarnock are on the map; the rest are in the table.
Is this the asking price?
No. This is the price actually paid, as declared to Revenue for stamp duty. It excludes VAT on new builds in the register, so we add 13.5% back for new homes to make them comparable.
