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 Advantage: A B1 BER rating indicates good energy efficiency, likely resulting in annual energy costs of approximately €900-€1,300 for this 83m² home, compared to €1,800-€2,400 for a D-rated property.
Space Efficiency: At 83m² with 3 bedrooms and 1 bathroom, the property offers a functional layout, with a median price per square meter of €7,592 within 1km suggesting good value for the space provided.
Investment Opportunity: Upgrading from a B1 to an A-rated BER, which would involve insulation, window, and heating system improvements, could cost an estimated €10,000-€15,000 and potentially increase the property's value by €15,000-€25,000, offering a solid return.
Hypothesis: Given the B1 BER rating and 83m² size, a strategic investment in enhancing the property to an A3 rating could unlock a further €50-€70 per square meter in value, considering the average price per square meter of €7,592 within 1km.
Amenities
Transport Hub: The area is served by Dublin Bus routes 75, 114, and 175, providing direct access to Blackrock DART station (approx. 2.5km) and major employment hubs.
Local Conveniences: Residents have close proximity to Deansgrange Shopping Centre, featuring SuperValu and a range of local retailers, pharmacies, and cafes, enhancing daily life.
Educational Access: The property is situated within catchment areas for notable schools including Hollypark Girls' National School and St. Andrew's College, offering strong educational options.
Hypothesis: The presence of multiple bus routes connecting directly to the DART line, combined with a high density of primary and secondary schools within a 2km radius, creates a significant family appeal that supports long-term property value appreciation.
