Where this price would put the property, if it were the value on 1 November 2025. This sale is from 2017, so it is a poor guide to a 2025 value and the real band is probably higher.
LPT is self assessed. The owner declares what the property was worth on 1 November 2025 and that declaration, not this sale, sets the charge for 2026 to 2030. How close a sale price gets you. Figures checked 8 August 2026.

Where this comes from
Every figure here is a sale filed for stamp duty and published by the Property Services Regulatory Authority, used under the Creative Commons Attribution 4.0 licence. The register carries no buyer or seller names and neither does this page. Transactions marked as not full market price remain in the history and carry that label. They are excluded from the market comparisons.

Worth reading beside this
Why the price on the register is not what the buyer paid
About 10.4% of sales in our town-level comparison sample are filed without the VAT the buyer paid on top. A €400,000 new build appears as €352,423. How to spot one and what to add back.
Stamp Duty on a house, and when the 6% band bites
1% up to €1 million, 2% to €1.5 million and 6% above it, charged in slices rather than all at one rate. What that comes to on a real price.
Working out a Local Property Tax band from a sale price
LPT is charged on what the owner declared the property was worth on 1 November 2025. A sale price is a hint at that, and a weaker hint the older the sale.
