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 indicates a good energy efficiency, meaning annual energy costs are likely to be around €1,800-€2,200, significantly lower than the €2,800-€3,500 estimated for a typical D-rated property of this size in the area.
Details
- Spacious Living: With 145m² of living space, this property is 6.5% larger than the average property size of 138.9m² within 1km over the last 180 days, offering more generous accommodation than the typical local offering.
- Upgrade Potential: Improving the BER from B3 to A-rated could cost an estimated €5,000-€8,000 in targeted insulation and heating upgrades, potentially increasing property value by €10,000-€15,000 and further reducing annual energy costs by €500-€700.
- Hypothesis: Given the strong demand for larger family homes in Booterstown and the current BER of B3, a targeted investment of €10,000-€15,000 in further energy efficiency measures (e.g., heat pump installation) could elevate the BER to A2, potentially adding 5-7% to the property's resale value within two years due to heightened buyer preference for sustainable and cost-efficient homes.
Amenities
Excellent Transport Hub: The property is well-served by Dublin Bus routes 7, 46a, and 63, and within easy reach of the DART at Booterstown Station, providing swift commutes to Dublin City Centre.
Details
- Prime Educational Corridor: Located in close proximity to leading schools including Blackrock College (1km), St. Andrew's College (1.5km), and the UCD Smurfit Business School (2km), making it highly attractive for families.
- High Walkability: Residents can enjoy a short walk to local amenities such as the shops and cafes on Booterstown Avenue, and the expansive green spaces of Carysfort Park (500m) and Rockfield Park (700m).
- Hypothesis: The consistent demand and premium pricing in Booterstown are significantly influenced by the 'commuter belt' desirability, with properties offering direct access to the DART within a 10-minute walk, like this one, historically outperforming properties without such immediate transport links by 8-12% in terms of both capital appreciation and saleability.
