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 B3 Efficiency: The B3 BER rating suggests reasonable energy efficiency, likely resulting in annual energy costs of approximately €1,600-€2,000, which is competitive against older, lower-rated properties.
Details
- Generous Size & Space: At 460m², this detached home offers substantial living space, which is 5.5 times larger than the median sale price for similar broad types within 1km (916,000), indicating a significant value in terms of sheer square footage.
- Investment in BER Upgrade: Upgrading from a B3 to an A2 BER rating would likely cost €5,000-€8,000, potentially reducing annual energy costs by €600-€1,000 and could add an estimated €10,000-€15,000 to the property's value.
- Hypothesis: While the B3 BER is adequate, investing in further energy efficiency upgrades to an A rating could significantly differentiate this large property in the premium segment, potentially commanding a higher price premium than typical for properties with lower BERs, by appealing to increasingly environmentally conscious luxury buyers.
Amenities
Exceptional Transport Links: This property is well-served by Dublin Bus routes 44, 63, and 111, with the DART at Killiney station being approximately 1.5km away, offering excellent connectivity to Dublin City Centre.
Details
- Premier Educational Access: The area boasts prestigious educational institutions including Holy Child School (approx. 1km) and St. Joseph of Cluny Secondary School (approx. 1.2km), along with numerous primary schools within a short drive.
- High-Quality Lifestyle Amenities: Residents have access to numerous upscale restaurants, cafes, and boutique shops in Dalkey and Glasthule, as well as the natural beauty of Killiney Hill Park and nearby coastal walks within a 2km radius.
- Hypothesis: The concentration of high-performing schools and premium lifestyle amenities in Killiney, coupled with excellent transport links to Dublin, creates a 'super prime' location effect where property values are less sensitive to minor overvaluations and more driven by the unique combination of exclusive living, excellent education, and convenient city access, suggesting sustained demand and potential for capital growth.
