How this is calculated
We search the Property Price Register for closed sales near this property — matching by location, beds, property type, and where available, floor area (±20%). This gives us a set of genuinely comparable transactions.
Each sale is then time-adjusted to today using local price trends, so a sale from 18 months ago is inflated (or deflated) to reflect current market conditions. Where floor area is known, sales are also size-adjusted — a 90m² sale is normalised to what it would have sold for at this property's size. This means the figures you see aren't raw prices — they're what those same homes would likely sell for today, at this size.
Your bid strategy (opening offer, sealed bid range, walk-away ceiling) is then derived from the statistical distribution of these adjusted sales — with conservative safety margins applied when data is thin or dated.
Every figure comes from actual government-recorded sale prices. No asking prices, no agent estimates, no automated valuations.

Methodology
Closed sales time-adjusted to current market · size-weighted where floor area available · no asking prices or agent estimates used.
How adjustments work
- —Older sales inflated to current market level so stale data doesn't skew bands
- —Similar-sized properties weighted more heavily where floor area is known
- —Local price trends factored in when sufficient data exists; no artificial uplift otherwise
- —All figures from registered closed sales only — no asking prices, no agent estimates
Local Market Notes
Property Quality
BER Advantage: An A2 BER rating suggests annual energy costs of approximately €800-€1,200, compared to €1,800-€2,200 for a D-rated property of similar size, offering annual savings of €1,000-€1,400.
Spacious Configuration: With 134 sqm of living space and 4 bathrooms for 3 bedrooms, the property offers a high bathroom-to-bedroom ratio (1.33), enhancing its appeal and potential value.
Value Optimization Potential: While the BER is excellent, further optimization for potential buyers could involve minor aesthetic upgrades to align with current design trends, potentially adding €5,000-€10,000 in value without significant structural changes.
Hypothesis: The significant investment in an A2 BER rating indicates a forward-thinking design that may correlate with higher build quality and better sound insulation compared to older properties in the area, contributing to a premium that isn't fully captured by standard price-per-sqm metrics.
Amenities
Transport Hub Access: Located in Castleknock, Dublin 15, residents have access to Dublin Bus routes 38, 38A, 38B, and 38D which connect to key city areas, and the nearby train station at Castleknock provides direct access to Dublin city center.
Educational Proximity: The area is well-served by educational facilities, including Scoil Thomáis Primary School, St. Vincent's Castleknock College, and Castleknock Community College, all within a short distance.
Local Retail and Leisure: Residents can easily access the shops and services in Castleknock Village, including supermarkets like Dunnes Stores and Lidl, as well as numerous cafes and restaurants, with the expansive Phoenix Park a short drive away.
Hypothesis: The strategic placement of the property within Castleknock, a well-established suburb with a strong reputation for family amenities and good schools, will likely continue to support property value appreciation, even if recent comparable sales show a slight premium compared to the asking price.
