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
Energy Efficiency Advantage: This B3 BER rating is stronger than the 100% of properties with unknown BER ratings within a 1km radius over the last 180 days, potentially offering lower energy bills.
Details
- Cost-Effective Upgrades: Investing in upgrading this B3 BER to an A-rated standard could cost approximately €8,000-€12,000, potentially increasing property value by €15,000-€20,000 and offering annual savings of €1,000-€1,400 compared to D-rated properties.
- Compact Design: At 92m², this semi-detached house is slightly smaller than the average property size of 103m² within a 1km radius over the last 180 days, suggesting efficient use of space but potentially less room for larger families.
- Hypothesis: Given that 100% of nearby properties had unknown BER ratings in the last 180 days, this property's B3 rating offers a clear competitive advantage, and further investment in energy efficiency could unlock a significant premium beyond the current asking price.
Amenities
Luas and Bus Connectivity: The property is well-served by the Luas Green Line at Leopardstown Valley stop (approximately 500m) and multiple Dublin Bus routes, including 47 and 114, providing direct access to Dublin city centre and surrounding areas.

- Hypothesis: The ongoing development of the Sandyford Business Estate and the surrounding residential areas, coupled with the established transport links, suggests a continued increase in demand for properties in Leopardstown Valley, potentially driving further price appreciation.
