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 Rating Opportunity: The C3 BER rating suggests potential for energy efficiency upgrades; investing €8,000-€12,000 to improve to a B2 rating could increase property value by €15,000-€20,000, while reducing annual energy costs from an estimated €1,800-€2,200 to €800-€1,200.
Details
- Size Efficiency: At 70.0m², this duplex is smaller than the average property size of 90.5m² within a 1km radius over the last 180 days, offering potential for a more compact and potentially more affordable entry point for buyers.
- Configuration Match: With 2 bedrooms and 2 bathrooms, this property aligns with the median of 2 bathrooms sold within 1km over the last 90 days, though it falls short of the median of 3 bedrooms in the same radius.
- Hypothesis: Given that 100% of properties within 1km over the last 180 days have an unknown BER rating, this property's C3 rating, while not top-tier, provides a clear benchmark for potential energy efficiency improvements. A strategic upgrade could offer a value uplift of €15,000-€20,000 for an investment of €8,000-€12,000, a 6.67% to 12.5% ROI on upgrade costs.

- Hypothesis: The strong connectivity through multiple Dublin Bus routes and nearby train services, coupled with the significant retail and recreational offerings of Blanchardstown Shopping Centre and Phoenix Park within close proximity, positions Castleknock as a highly desirable residential area. This amenity-rich environment likely contributes to the robust demand and quick sales observed in the local market.
