Suburbs Where Buying Is Now Cheaper Than Renting: Dublin’s New Property Calculus

Monthly mortgage repayments are now lower than typical rents in parts of Dublin’s outer suburbs, according to new figures compiled by the property tracking firm Daft.ie and corroborated by several local estate agencies. House-hunters in areas like Lucan and Clonsilla are finding it’s cheaper to buy than to rent, a rare reversal in a city long dominated by soaring rental costs and tight sales supply.

Why the Balance Has Shifted

This shift comes on the heels of a turbulent two years for Dublin’s property market, marked by a spike in rental demand as new arrivals—in particular thousands of Ukrainian and international students—flooded the capital. At the same time, higher ECB rates and stricter mortgage requirements cooled bidding wars, leading to subdued house price growth. With average Dublin rents reaching a record €2,350 for a two-bed apartment as of June 2026 (Daft.ie), but some mortgage repayments now dipping well below that threshold, the classic rent-vs-buy calculation has changed in key districts.

Lucan, with its strong bus links and proximity to Liffey Valley Shopping Centre, is at the heart of the change. According to Sherry FitzGerald Lucan, the monthly mortgage for a typical three-bed semi—currently listed at €385,000—now runs at about €1,900 after a 20% deposit, assuming a 3.8% fixed rate over 30 years. That’s €400 less than the €2,300 average rent for similar properties in the area. Clonsilla and Ongar, often overshadowed by pricier Castleknock next door, show a similar pattern. Local agency DNG reports a surge in sales inquiries from renters tired of annual hikes and limited security of tenure.

Pricing, Data and What to Know

The affordability tipping point arrives from two converging trends. Dublin rents have climbed 6.4% year-on-year, far outpacing a modest 1.2% growth in sale prices in Dublin 15 and Dublin 22 (source: Daft.ie Q2 2026). As a result, monthly repayments on a standard mortgage for entry-level homes from Adamstown to Tyrellstown are now €250 to €550 cheaper than typical rents. Even in Tallaght, traditionally balanced between owners and renters, MyHome.ie listings show three-bed semis can be bought for €375,000 to €395,000, with after-tax repayments often €200 or more below the rent for similar properties.

Would-be buyers should note, however, that these calculations assume buyers have a 20% deposit—no small sum in a market where the Central Bank’s macroprudential rules still bite. Local experts at the Dublin Housing Observatory warn that high deposit hurdles and legal costs remain a barrier for many. Still, first-time buyers can avail of government supports like the Help to Buy scheme (up to €30,000) and the First Home Scheme, which can contribute to a deposit top-up if the mortgage approval falls short of the purchase price.

Those considering a move should act quickly. Analysts at Savills Dublin point to ongoing rental supply pressures and the likely return of ECB cuts in early 2027, both of which could nudge prices upward, closing the gap. For now, pockets of affordable ownership from Lucan to Clonsilla offer a window that Dublin renters haven’t seen in years.
