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
Efficient Energy Rating: The B3 BER rating indicates a reasonably efficient property, likely resulting in annual energy costs of €1,100-€1,500, which is approximately €400-€700 lower than comparable D-rated properties of similar size in the area.
Optimal Configuration: With 2 bedrooms and 2 bathrooms within a 92m² footprint, the property offers a balanced and desirable layout for its size, aligning with the median of 3 bedrooms and 2 bathrooms seen in the local market, but with a more efficient use of space for two occupants.
Value Optimization Opportunity: While the B3 rating is good, strategic upgrades to an A-rating could cost €8,000-€12,000, potentially increasing the property's value by €15,000-€20,000 and further reducing annual energy costs by another €300-€400.
Hypothesis: The current B3 BER rating, while good, represents a missed opportunity for maximum value creation, as the 100% of properties with unknown BER ratings within 1km suggest a market segment that is not yet fully capitalizing on energy efficiency as a premium driver, implying a buyer willing to invest in further upgrades could achieve a significant uplift in resale value.
Amenities
Excellent Transport Links: The property is well-connected with Dublin Bus routes 25, 66, and 67 serving the Porterstown area, providing direct access to Dublin city centre and surrounding suburbs, with these routes typically located within a 500m walk.
Key Local Facilities: Residents benefit from proximity to Connolly Hospital Blanchardstown (approximately 2km), with a variety of local shops and supermarkets in the nearby Carpenterstown and Blanchardstown Shopping Centre (approximately 3km).
Educational Catchment: The area is served by St. Francis Xavier Senior National School (approximately 800m) and Hartstown Community School (approximately 1.5km), offering accessible educational options for families.
Hypothesis: The consistent demand for properties in D15, as reflected by the high transaction volumes within 1km and 3km, is likely driven by a combination of improving local infrastructure, such as the planned expansion of the N4/M4 corridor, and the increasing desirability of areas offering a balance of suburban living with good access to essential amenities and employment hubs.
