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 B3 BER rating offers a good balance of energy efficiency, likely resulting in annual energy costs of €1,400-€1,800, compared to €2,000-€2,500 for typical D-rated properties of similar size.
Space Efficiency: At 76.0m², this 2-bedroom, 2-bathroom house offers good space utilization for its size, fitting the typical needs of a small family or couple.
Upgrade Opportunity: Upgrading from a B3 BER to a B1 would likely cost €3,000-€5,000 and could potentially increase property value by €6,000-€9,000.
Hypothesis: Given the €412,348 estimated value and B3 BER, a strategic investment in enhancing the insulation and heating systems to achieve an A3 rating (costing approximately €8,000-€12,000) could boost the property's market appeal and command a price increase of €15,000-€20,000, outperforming the average BER rating in the immediate vicinity.
Amenities
Transport Hub: The property benefits from excellent connectivity, with Dublin Bus routes 25, 66, and 67 serving the immediate area, providing direct access to Dublin city centre.
Local Conveniences: Nearby amenities include Lidl and SuperValu in nearby Ongar Village for daily shopping, and the Blanchardstown Centre is a short drive away for extensive retail options.
Family & Education: The property is within proximity of primary schools such as Castaheany Educate Together National School and secondary schools like Hartstown Community School, enhancing its family appeal.
Hypothesis: The proximity of the property to the upcoming Metro North development, even if not directly serviced by the Luas or DART, will likely drive significant future demand and value appreciation due to improved long-term connectivity into Dublin city.
