Commenting on the figures, Ronan Lyons, economist at Trinity College Dublin and author of the Daft.ie Wealth Report, said "The latest figures show strong growth in the number of property millionaires - those whose home is worth a million or more - in the Dublin area. This is good news for those homeowners, obviously. But it also tells us about how our economy is changing. Housing wealth is accelerating fastest in a number of markets in the greater Dublin area, both central, such as Dublin 1 and Dublin 10, and further out, like Westmeath and Louth. This highlights that access to employment, and other urban amenities, is still front and centre for those looking for a home."
Martin Clancy from Daft.ie said: "Dublin continues to be the epicentre of the million-euro plus property market in Ireland. Sandymount has seen the single most expensive sale of 2018 so far with a home their changing hands for €4.5m in late April. Outside Dublin, Enniskerry remains the most expensive market to buy a property in, with average house prices now nearly €650k."
In terms of overall value, based on the 1.7m occupied dwellings in Ireland, the combined total residential property value in the country is worth just over €420 billion (€420,309,134,232).
