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 C3 Upgrade Opportunity: Upgrading the C3 BER to a B2 rating would likely cost between €8,000-€12,000, potentially increasing the property's value by €15,000-€20,000 and improving its marketability.
Details
- Size Efficiency: At 76m², this property is slightly larger than the average property size of 73.3m² recorded within a 1km radius over the last 180 days.
- Value Optimisation: The property has 3 bedrooms and 1 bathroom, which is below the median of 2 bathrooms within a 1km radius over the last 180 days, indicating a potential opportunity to add value through an additional bathroom installation, which could increase resale value by approximately €10,000-€15,000.
- Hypothesis: Properties in this immediate Clondalkin area with a C3 BER rating are currently trading at a discount of approximately 3-5% compared to properties with a B-rated BER. However, the high cost of BER upgrades and the prevalence of C3 ratings across 100% of observed properties in the last 30-day period within 1km suggests that buyers may be prioritizing location and size over immediate energy efficiency improvements.
Amenities
Transport Connectivity: Residents have access to Dublin Bus routes 25, 66, and 67, providing direct links to Dublin city centre, and are within a reasonable distance of the Luas Red Line.
Details
- Local Amenities: The area is served by The Square Shopping Centre in Tallaght for retail, and local schools include Moyle Park College and Holy Spirit Boys National School.
- Healthcare Access: Connolly Hospital Blanchardstown is accessible within a short drive, offering comprehensive medical services, and several local pharmacies are available.
- Hypothesis: The ongoing development of the Lucan and Clondalkin area, with potential for enhanced public transport links, is likely to further boost property values within a 3km radius by an additional 4-6% over the next two years, attracting more families seeking suburban living with good commuting options.
