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 Upgrade Opportunity: Upgrading the D1 BER rating to a B2 could cost an estimated €8,000-€12,000 and potentially increase the property's value by €15,000-€20,000.
Size Advantage: At 120m², the property is larger than the average property size of 90m² within a 1km radius over the past 180 days, offering more space than typical local listings.
Configuration Mismatch: While having 4 bedrooms, the median bed count in the 1km radius over 180 days is 3, suggesting this 4-bedroom layout might appeal to a specific buyer segment.
Hypothesis: The D1 BER rating presents a significant opportunity for value enhancement, and investing in energy efficiency upgrades could yield a strong return, especially considering that 100% of properties within 1km over the last 180 days have an unknown BER, potentially creating a competitive advantage.
Amenities
Transport Links: The area is well-served by Dublin Bus routes 25, 25A, 25B, 25D, 25X, 66, 66A, 66B, 66E, 66N, 67, 67A, 67X, providing comprehensive connectivity.
Local Education Hub: Proximity to schools like Castleknock College, St. Vincent's Castleknock College, and Scoil Thomáis ensures strong educational amenities for families.
Green Space Access: Residents benefit from close proximity to the vast Phoenix Park (approximately 1.5km), offering extensive recreational opportunities and natural beauty.
Hypothesis: The strong integration of transport links (bus routes 25, 66, 67) with established educational institutions like Castleknock College and extensive green space in Phoenix Park suggests Castleknock is a highly desirable residential location for families prioritizing convenience, education, and lifestyle.
