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
Exceptional Energy Efficiency: With an A2 BER rating, this property's annual energy costs are estimated to be between €800-€1,200, significantly lower than the €1,800-€2,200 for D-rated properties of a similar size.
Generous Living Space: At 120m², this detached property offers substantial living space, aligning with desirable configurations for families and those seeking comfortable accommodation.
Value Optimisation Opportunity: While already excellent, achieving a B2 BER rating through minor efficiency upgrades could potentially increase property value by an estimated €15,000-€20,000, at a cost of €8,000-€12,000.
Hypothesis: The combination of a high BER rating and ample size suggests this property is positioned for long-term value retention and potential capital appreciation, especially if market trends continue to favour energy-efficient and well-proportioned homes.
Amenities
Excellent Connectivity: The property is well-served by Dublin Bus routes 25, 66, and 67, offering direct links to Dublin city centre, and is within reasonable proximity to train stations for further commuting options.
Comprehensive Local Services: Residents have easy access to a range of amenities including St. Mary's Primary School and St. Patrick's Secondary School, along with shops and healthcare facilities within the Castleknock area.
Abundant Green Spaces: Proximity to the expansive Phoenix Park (1km) provides significant recreational opportunities and a high quality of life, complemented by local parks and walking routes.
Hypothesis: The established infrastructure and amenity-rich environment of Castleknock, particularly its strong educational and recreational offerings, will likely continue to drive demand and support property values, making it a highly desirable location for families and professionals.
