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
C3 BER Potential: With a C3 BER rating, energy efficiency could be improved; upgrading to a B2 could cost approximately €8,000-€12,000 and potentially increase the property's value by €15,000-€20,000, while reducing annual energy costs compared to lower-rated homes.
Generous Space: At 140m², this 4-bedroom, 2-bathroom detached house offers ample living space, which is competitive and appealing for family buyers within this sought-after Dublin location.
Value Optimization: Given the C3 BER, investing in insulation and heating upgrades could optimize long-term value and reduce operational costs, turning a potential drawback into an investment opportunity.
Hypothesis: The property's C3 BER rating, while not optimal, places it in a mid-tier energy performance. Further investment to achieve a B1 or A3 rating could unlock significant future capital growth and rental appeal, especially as energy efficiency becomes a more prominent buyer consideration.
Amenities
Excellent Transport Links: The property is well-served by Dublin Bus routes 7, 7A, 45A, 63, 111 operating from nearby stops, providing direct access to Dublin city centre and surrounding areas.
Educational Hub: Proximity to esteemed educational institutions like Rathdown School (approx. 0.5km), St. Andrew's College (approx. 2km), and the National Maritime College of Ireland (approx. 3km) enhances its family appeal.
Village Lifestyle: Within walking distance are the amenities of Dún Laoghaire, including its pier, shopping centres like Dun Laoghaire Shopping Centre, and a variety of cafes and restaurants like Olivio and Hartley's.
Hypothesis: The strong connectivity to major employment hubs via multiple bus routes and the DART (Dún Laoghaire Station approx. 1.5km), combined with excellent schooling and a vibrant coastal lifestyle, solidifies Glenageary as a prime residential location, likely to sustain or increase property values.
