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 Improvement Opportunity: Upgrading the D2 BER rating to a B2 would likely cost between €8,000-€12,000, but could increase the property's value by an estimated €15,000-€20,000, offering a positive return on investment.
Energy Cost Differential: With a D2 BER rating, this property's annual energy costs are estimated to be €1,800-€2,200, compared to the €800-€1,200 for comparable B-rated properties, representing an annual saving of €1,000-€1,400.
Space Efficiency: At 87m², this 3-bedroom, 1-bathroom house offers a modest living space, with the 1 bathroom potentially being a constraint for larger families or frequent guests, impacting its market appeal and future resale value compared to properties with more bathrooms.
Hypothesis: Given that the median sale price for a 'same type' house within 1km is €1,117,500 compared to this property's asking price of €695,000, a significant enhancement in bathroom facilities (e.g., adding a second bathroom) could potentially bridge a substantial portion of this valuation gap.
Amenities
Transport Hub Access: This property benefits from excellent connectivity, being within reasonable distance of DART stations in Dun Laoghaire and Salthill, and numerous Dublin Bus routes, including routes 46A and 75, providing direct access to Dublin city centre and surrounding areas.
Educational and Healthcare Proximity: Residents have access to esteemed educational institutions like Rathdown School and CBC Monkstown, while essential healthcare is provided by the Royal Hospital Donnybrook and St. Vincent's University Hospital, both within a short commute.
Retail and Leisure Destinations: The property is ideally situated near the extensive retail offerings of Dun Laoghaire town centre, including major supermarkets like Dunnes Stores and Lidl, and is a short drive from the shopping centres in Blackrock and Stillorgan.
Hypothesis: The high concentration of parks and coastal amenities, such as the People's Park, Dun Laoghaire Pier, and Sandycove beach, within walking distance, coupled with the direct DART line to the city, suggests a strong potential for capital appreciation driven by lifestyle demand from both young professionals and families seeking coastal living with urban access.
