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 Upgrade Potential: Upgrading the D2 BER rating to a B2 would likely cost between €10,000 - €15,000 and could increase the property's value by an estimated €20,000 - €25,000, representing a strong return on investment.
Details
- Size Advantage: At 220m², this detached 6-bedroom property is significantly larger than the average property size of 130m² within a 1km radius, offering ample space for larger families or those seeking extensive living areas.
- Configuration Mismatch: While the property boasts 6 bedrooms and 3 bathrooms, the market data within a 1km radius indicates a median of 3 bedrooms and 2.5 bathrooms, suggesting this property may be over-configured for typical local demand.
- Hypothesis: The D2 BER rating, common across 100% of properties within 1km in the last 180 days, presents a significant opportunity; however, the substantial size and bedroom count of this property, exceeding local median configurations, may require targeted marketing to attract buyers seeking such expansive accommodations rather than standard family homes.
Amenities
Transport Links: This property is well-served by Dublin Bus routes 25, 66, and 67, with potential access to the Luas Red Line via a connection from nearby bus routes, offering good connectivity to Dublin city centre.
Details
- Educational Hub: The area benefits from proximity to St. Mochta's National School (0.8km), Castleknock College (1.2km), and Hartstown Community College (1.5km), catering to a range of educational needs for families.
- Local Conveniences: Residents have access to The Village Centre Castleknock (1.5km) for shopping, The Blanchardstown Centre (2.5km) for retail therapy, and Connolly Hospital (3.0km) for healthcare needs.
- Hypothesis: While specific transport route details to the Luas Red Line are not provided, the concentration of schools and proximity to major retail centres like Blanchardstown suggests that this location is highly desirable for families and those seeking suburban convenience, driving demand and potentially future value appreciation.
