Suburbs Where Buying Beats Renting: Dublin’s Surprising New Affordability Hotspots

For the first time since the pandemic, buying a home in certain Dublin suburbs is now cheaper than renting—sometimes by hundreds of euro a month. New figures compiled for The Daily Dublin show that areas like Lucan and Finglas have swung in favour of first-time buyers, despite overall affordability challenges elsewhere in the city.

The shift comes as rents in the capital notch yet another record high, with Daft.ie’s June report showing average monthly rents citywide now exceed €2,330—a 7% jump in a year. Higher interest rates have cooled house price growth, but many would-be buyers have remained wary amid headlines of surging living costs and limited supply. For renters fed up with annual increases, however, the economic equation is starting to flip.

Lucan and Finglas Lead the Affordability Charge

Specific postcodes have become unlikely affordability havens. In Lucan, three-bed semis on Griffeen Avenue are now selling for around €405,000, according to listings tracked through Sherry FitzGerald. With a 10% deposit and a 30-year fixed-rate mortgage at 4.3%, this translates into monthly repayments of roughly €1,817—well below the average Lucan rent of €2,210 for equivalent properties.

Finglas, long a staple for renters priced out of the city centre, is showing a similar reversal. Average asking prices for mid-terrace homes on Casement Road this June hovered near €360,000. A mortgage on that amount runs about €1,617 a month, compared to a typical rent exceeding €2,050. Martin Property Consultants, with offices in the area, reported that more viewings in 2026 than last year are first-time buyers actively comparing rent-vs-buy breakdowns in real time.

Crunching the Numbers

The overall city picture remains challenging—Knight Frank pegged Dublin’s median house price at €520,000 in June, keeping home ownership out of reach in many zones. But for Dublin 20 and Dublin 11, the tipping point is evident. Data shared by the Banking & Payments Federation Ireland (BPFI) shows that average monthly mortgage repayments for Dublin first-time buyers stood at €1,820 in May, while new rental tenancies in the same footprint ran to €2,310 on average. Local letting agent Owen Reilly’s June snapshot found several zip codes—especially close to the Red Line Luas and around Carton Park Retail Centre—where it is now €400–€600 per month cheaper to buy than rent.

The National Housing Agency referenced government Help-to-Buy and First Home Scheme uptake hitting record highs this spring, especially in new-build developments in west Dublin, suggesting that buyers are responding to the changing affordability dynamic.

For those hoping to capitalise on the gap, experts warn the window may not last: “It’s a rolling calculation—mortgage rates could rise again, or investors may swoop in,” one local broker cautioned. Anyone considering a move should factor in stamp duty, legal fees, and the practicalities of assembling a deposit. The BPFI offers a free mortgage calculator and independent guidance on its website, and several local credit unions have increased outreach sessions for prospective buyers this summer. But as it stands this July, for the first time in nearly a decade, Lucan, Finglas and similar outer suburbs are giving home hunters a rare advantage over renters.
