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 Rating Impact: With a C2 BER rating, this property is likely to have higher annual energy costs compared to A or B-rated properties, potentially in the range of €1,400-€1,800 annually, versus €800-€1,200 for A-rated homes of similar size.
Substantial Size for Bedrooms: The property offers a generous 120m² for only 1 bedroom, suggesting a very spacious layout but potentially inefficient use of space for a typical residential profile.
Value Optimization Opportunity: While the C2 BER is decent, an upgrade to a B2 rating, costing an estimated €8,000-€12,000, could potentially increase the property's value by €15,000-€20,000 and reduce annual energy bills by €300-€500.
Hypothesis: The significant difference between the property's 120m² size and its single bedroom suggests an intentional design for expansive living spaces or a potential for easy conversion into multiple bedrooms. Given the C2 BER, there's a clear opportunity to enhance its market appeal and long-term value through targeted energy efficiency upgrades, which could unlock an additional 5-7% in value based on typical buyer premiums for greener homes.
Amenities
Excellent Transport Connectivity: The area is served by multiple Dublin Bus routes, including 25, 66, and 67, providing direct access to Dublin city centre, and is in proximity to Luas Red Line services.
Key Local Facilities Nearby: Residents benefit from immediate access to essential services, with Connolly Hospital and a range of shopping facilities at The Square Tallaght within a short distance.
Enhanced Walkability: The Rathborne area offers good walkability, with pedestrian-friendly paths and access to local parks and community centres, making daily errands convenient.
Hypothesis: The proximity to the Luas Red Line and numerous bus routes, combined with the availability of major shopping centres like The Square and essential healthcare at Connolly Hospital, positions this property as a strong contender for young professionals and families seeking both convenience and connectivity within Dublin 15, suggesting that amenities are a significant value driver here.
