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 this D-rated BER to a B2 rating is estimated to cost between €8,000-€12,000 but could increase the property's value by €15,000-€20,000, representing a sound investment.
Size Efficiency: At 170m², this property offers ample living space, which is generally well-received in sought-after areas like Blackrock, however, its price positioning is key for value realization.
Value Optimization: With a D BER rating, annual energy costs are estimated at €1,800-€2,200; investing in insulation and heating upgrades could reduce this by €1,000-€1,400 annually compared to the current rating.
Hypothesis: Given the median sale price for the same broad property type within 1km is €1,211,740, this property's D BER rating may be a primary factor contributing to its lower valuation compared to potentially better-rated properties within that segment, suggesting that BER improvements could directly bridge this price gap.
Amenities
Excellent Connectivity: Proximity to DART stations in Blackrock and Seapoint provides swift access to Dublin city centre, complemented by Dublin Bus routes like the 7 and 4 to various city destinations.
Prime Educational Hub: The area is rich in educational facilities, including Blackrock College, St. Andrew's College, and the French School, alongside numerous highly-regarded primary schools, making it very attractive for families.
Local Lifestyle Hub: Residents benefit from the vibrant retail and dining scene in Blackrock village, with options like Avoca, gourmet food shops, and numerous cafes and restaurants, as well as proximity to Carysfort Park for recreation.
Hypothesis: The high concentration of high-achieving schools within walking distance and excellent transport links to employment hubs like Sandyford and the city centre solidify Blackrock's premium status, suggesting that properties here with a D BER rating may still command higher prices due to location demand than higher-rated properties in less desirable areas.
