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 Rating Impact: With a D1 BER rating, upgrading to a B2 rating could cost an estimated €8,000-€12,000 but potentially increase the property's value by €15,000-€20,000, while current annual energy costs are estimated at €1,800-€2,200.
Details
- Size Efficiency: This property at 94.0m² is larger than the average property size of 73.3m² sold within a 1km radius over the last 180 days, offering more space for the price.
- Configuration Value: The 3 bedrooms and 3 bathrooms configuration aligns with the median of 3 bedrooms and 2 bathrooms within a 1km radius, indicating a suitable and desirable layout for the local market.
- Hypothesis: Given the D1 BER rating, there is a significant opportunity for value enhancement through targeted energy efficiency upgrades; a strategic investment in insulation and heating systems could not only reduce annual running costs but also significantly improve its appeal and resale value in a market where sustainability is increasingly valued.
Amenities
Transport Connectivity: This location is served by Dublin Bus routes 150 and 151, providing direct access to Dublin city centre, and is approximately a 30-minute walk to the Red Cow Luas stop.
Details
- Local Amenities Access: Residents have convenient access to The Square Shopping Centre in Tallaght, approximately 2km away, and local supermarkets like Lidl and Dunnes Stores are within a 1km radius.
- Educational Infrastructure: Proximity to primary schools such as St. Killian's Senior Primary School (1km) and secondary schools like Coláiste Bríde (1.5km) offers good educational options for families.
- Hypothesis: The planned expansion of the Luas Red Line and potential new housing developments in Clondalkin could significantly boost local infrastructure and property values within the next five years, making properties like this more attractive to commuters and families seeking well-connected, up-and-coming areas.
