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
Superior Energy Efficiency: With an A2 BER rating, annual energy costs are estimated to be €800-€1,200, a significant saving of €1,000-€1,400 annually compared to a D-rated property of similar size.
Details
- Optimized Space Configuration: The 112 sqm property is configured with 3 bedrooms and 3 bathrooms, matching the median bathroom count within 1km (3.0) and offering a slightly lower bedroom count than the median (4.0) but a more efficient ratio for its size.
- Value Through Upgrades: While the A2 BER is excellent, a hypothetical upgrade from a D-rated property (typical in some wider areas) to a B2 rating would typically cost €8,000-€12,000 and potentially increase property value by €15,000-€20,000, demonstrating the market's appreciation for energy efficiency.
- Hypothesis: The A2 BER rating ensures immediate market appeal and lower running costs, but the smaller size (112 sqm) compared to the average property size of 151 sqm within 1km suggests potential buyers might be willing to pay a premium for the energy efficiency over outright space, provided the internal layout is highly functional.
Amenities
Excellent Connectivity: Situated in Castleknock, the property benefits from proximity to Dublin Bus routes 38, 38A, 38B, and 38D serving the city centre, and is a short drive to the M50 for wider connectivity.
Details
- Family-Centric Location: This area is well-served by educational facilities including Scoil Thomáis National School (under 1km) and Castleknock Community College (1.5km), alongside childcare options like Little Stars Creche (1.2km).
- Local Convenience: Residents have easy access to the shops and supermarkets at the nearby Blanchardstown Shopping Centre and a range of local restaurants and cafes in Castleknock village, all within a 2km radius.
- Hypothesis: The property's location in Castleknock, known for its strong community feel and excellent schools, combined with its high BER rating, positions it favourably for families seeking quality of life and good commuter links, suggesting that its premium price is partially justified by its family-friendly and well-connected attributes, despite being further from central Dublin's direct Luas/DART lines.
