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 C2 Energy Efficiency: A C2 BER rating suggests moderate energy efficiency. Upgrading to a B2 rating could cost approximately €8,000-€12,000 but is estimated to increase property value by €15,000-€20,000, representing a solid return on investment.
Space Utilisation: With 90m², this 3-bedroom, 2-bathroom detached property offers a density of 9.7m² per room (90m² / 9 rooms including bathrooms), which is below the typical density for comparable properties in well-established Dublin suburbs, suggesting efficient use of space.
Value Optimization Potential: Given the C2 BER, strategic upgrades to insulation, heating, and window replacements could significantly improve energy costs, estimated to save €700-€1,000 annually compared to D-rated properties, making it a more attractive long-term prospect.
Hypothesis: The C2 BER rating, while not poor, presents a clear opportunity for value enhancement through targeted energy efficiency upgrades. The relatively low average price per square meter within 1km suggests that properties with better BER ratings are commanding a premium, making this an investment play.
Amenities
Transport Hub Access: The property is well-connected by Dublin Bus routes 25, 25A, 25B, 66, and 67 serving the area, with the M50 motorway accessible within a short drive, facilitating easy commutes to Dublin City Centre and beyond.
Educational and Healthcare Proximity: The location offers excellent access to educational facilities including St. Brigid's National School and Castleknock Community College, as well as healthcare services like the Connolly Hospital Blanchardstown, all within a 2km radius.
Local Retail and Recreation: Residents benefit from proximity to retail hubs like The Blanchardstown Centre and smaller local shops in Castleknock village, alongside leisure options such as the Phoenix Park and local sports clubs, enhancing lifestyle appeal.
Hypothesis: The concentration of amenities within a 2km radius, coupled with the property's competitive pricing relative to local sales, suggests that Castleknock Elms is an emerging micro-market where improved transport infrastructure or new residential developments could further drive up demand and property values.
