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: The B2 BER rating positions this property well, with estimated annual energy costs of €1,500-€2,000, compared to €2,500-€3,500 for a similar-sized G-rated property.
Ample Space: With 311m², the property offers 100m² more space than the median 5-bedroom house in the 1km radius, which has a median sale price of €564,000, indicating a significant value attributed to size.
Value Optimization: Upgrading from a B2 BER to an A-rated BER could cost €10,000-€15,000 and potentially increase property value by €20,000-€30,000, offering a clear ROI.
Hypothesis: Given the property's substantial size and B2 BER, a targeted investment in energy efficiency upgrades, such as improved insulation and heating controls, could further enhance its appeal to high-net-worth buyers and potentially close the price gap with premium A-rated properties in Dublin 15.
Amenities
Transport Hub: Close proximity to Dublin Bus routes 25, 25A, 66, 67, and 25X offers direct access to Dublin city center, and the M50 motorway is easily accessible for wider commuting.
Educational Cluster: Located near esteemed institutions such as Educate Together National School Castleknock (0.8km), St. Brigid's National School (1.2km), and Castleknock College (1.5km), providing strong family appeal.
Local Conveniences: Amenities include SuperValu Castleknock (1km), Blanchardstown Shopping Centre (3km), and the Phoenix Park (2km) offering extensive retail, leisure, and green space options.
Hypothesis: The cluster of highly-rated primary and secondary schools within a 1.5km radius, combined with the significant green space of the Phoenix Park, creates a powerful family-centric lifestyle proposition that commands a premium, potentially explaining some of the property's higher valuation compared to areas with less established educational and recreational infrastructure.
