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: With an A3 BER rating, this property will have significantly lower annual energy costs, estimated at €800-€1,200 compared to €1,800-€2,200 for a typical D-rated detached house of similar size in the area.
Details
- Optimised Space: At 115 sqm with 3 bedrooms and 3 bathrooms, this property offers a good balance for its size, aligning with the median of 3 bedrooms and 2 bathrooms for properties within a 1km radius.
- Value Enhancement: Upgrading a D-rated property to a B2 standard can cost €8,000-€12,000, yielding a property value increase of €15,000-€20,000, making the current A3 rating a significant long-term asset.
- Hypothesis: The A3 BER rating represents a substantial upfront investment by the developer, which is likely being factored into the property's value; however, further passive house or smart home technology integration could potentially command an additional 5-8% premium in this quality-conscious segment of the market.
Amenities
Connectivity Hub: The property is well-served by Dublin Bus routes 75 and 118, offering direct access to Dún Laoghaire town centre and frequent connections to Dublin city.
Details
- Local Conveniences: Residents have convenient access to local shopping at Rochestown Avenue Shopping Centre, with further retail options at Cornelscourt Shopping Centre, and healthcare at the nearby Blackrock Clinic.
- Family & Leisure: Proximity to reputable schools like CBC Monkstown (1.5km) and St. Andrew's College (2km), combined with nearby leisure facilities such as the Dun Laoghaire Golf Club and the coastal walks along the piers, enhances lifestyle appeal.
- Hypothesis: The presence of the N11/M50 interchange within a 2km radius significantly enhances commute times to various business parks and the city centre, suggesting that properties with this accessibility command a consistent 10-15% premium over those without direct arterial road links.
