The Most Overpriced Areas in Ireland (Q2 2026)

It's not Dublin 4. It's not Dublin 6. The buyers paying the steepest premium over asking price in 2026 are in Tullamore, Sligo, and Edenderry — not the postcodes you'd expect.

We analysed every PPR sale we could match to its original listing price over the last 18 months — 21,353 transactions in total — and ranked Ireland's Eircode routing keys by how far the actual sale price drifted above the asking price. The results upend the “Dublin is the wildest market” assumption.

Methodology

For every sale where we could pair a Property Price Register record with its original listing asking price, we calculated:

premium % = (sale price − asking price) / asking price × 100

We then took the median premium per Eircode routing key (the first three characters of an Eircode, e.g. D04, F91). Median, not average — a single trophy sale at +60% can drag an average around. The median tells you what's happening to a typical buyer in that area.

Sample: 21,353 matched sales between October 2024 and April 2026. Areas with fewer than 75 matched sales excluded.

The Top 10

The Dublin Surprise

Now compare those numbers to the city everyone thinks is the wildest in the country.

The most expensive postcodes in the country show disciplined pricing. In Dublin 4 — the Ballsbridge/Sandymount belt — the median sale closes within 0.6% of the asking price. In Tallaght, the median sale closes exactly at asking, and only 39% of buyers go over.

Translation: in Dublin, the agents have got pretty good at pricing close to fair value. In the commuter towns and the regional cities, asking prices are systematically too low — either because agents are being deliberately conservative to drive bidding, or because the local market has heated up faster than asking-price calibration can keep up.

What this means if you're buying

• Buying in Maynooth, Celbridge, Newbridge, or anywhere in W23/W12? Budget at least 8–10% above the asking price. The “asking” is a starting gun, not a sale price.
• Buying in Dublin 4, 6, 14, 18 or 24? The asking price is a credible negotiation anchor. You can offer at or near asking and still be in the running.
• Buying in Sligo, Cavan, Monaghan, Limerick, or Tullamore? The local market is hotter than the asking prices reflect. A 5% premium is your floor; expect to compete.
• Anywhere in the country, look at the % of sales over asking column before you offer. If it's above 75%, you're in a bidding-war market and your strategy needs to reflect that. If it's below 50%, you have leverage.

What this means about the market

The story we usually tell ourselves is that Dublin drives Irish house prices. The data tells a different one: Dublin's pricing is converging on fair value while the commuter belt and the regions are running hot. The strongest premium-over-asking percentages are clustered in two places:

1. The Dublin commuter ring (Maynooth, Celbridge, Leixlip, Newbridge, Blessington, Kells, Edenderry) — buyers who couldn't afford Dublin priced out into towns that still feel “affordable” by comparison and bid them up.
2. Regional cities and towns with employment growth (Sligo, Limerick, Cavan, Monaghan) — supply isn't keeping up with renewed local demand.

If you want to know what's happening in Irish housing right now, don't look at Dublin 4. Look at Sligo and Maynooth.

How we did this

This analysis matches Property Price Register sales to their original listing asking price using BuyerIQ's listing-to-sale matching pipeline. We excluded sales flagged as not at full market price and prices outside €50k–€5m. We required at least 75 matched sales per area. The window is October 2024 to April 2026.
