Every Irish front door has its own unique Eircode, which makes the 7-character code the most precise key for looking up one home's sale history and context. Here is what an Eircode lookup can — and cannot — tell you about value.
Property Price Register addresses are typed free-text by solicitors, so one house can appear under several spellings and a text search will miss entries or mix up houses with similar names. An Eircode is unique to a single delivery point, so an Eircode-keyed lookup returns exactly one home's record.
This is why iHouse uses Eircode as its canonical property key: PPR transactions, Daft/MyHome listing history and the SEAI BER cert are merged onto one Eircode-identified record, so the price history doesn't fragment across address spellings.
For the property itself: past PPR sales of that door with dates and prices, its listing history (asking prices, photos, floor area, description at the time), and its BER rating where a cert exists.
For context: the surrounding area's sold prices for similar property types, Small Area demographics from CSO Census data, schools and transit, and environmental screens such as flood risk category and EPA radon classification. Together these are the raw material of a comparables-based estimate.
A past sale is not today's value. A 2016 price needs trend adjustment (the CSO Residential Property Price Index covers this by region), and any single figure can embed circumstances the register doesn't show — an executor sale, a sale between relatives, a derelict interior.
Public data also can't see current condition: renovations, an extension, or deterioration since the last sale are invisible until the next listing. Revenue's valuation guidance applies here too — value from several similar nearby sales, using the property's own history as one input, not the answer.
The Eircode gets you the right property's history and the right area's comparables — that's the starting evidence, and often enough for a realistic range. Condition and recent works still need eyes on the property, and formal purposes (mortgage, probate, legal) require a chartered valuer regardless.
Finding an address's Eircode is free at finder.eircode.ie. On iHouse, searching an Eircode returns that property's page with its sale history, listing record and area context; the paid valuation report goes further with a modelled fair-value range and matched comparables.
Then it has no PPR record — the register only covers sales completed since 1 January 2010. Valuation falls back entirely on comparables: recent sales of similar homes nearby, adjusted for size, condition and BER, plus any listing history the property has from unsold marketing attempts.
