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 C1 BER rating to a B2 could cost approximately €8,000-€12,000, potentially increasing the property's value by €15,000-€20,000 and attracting a wider buyer pool.
Details
- Average Size for Area: At 83.0m², this semi-detached property is slightly smaller than the average 89.1m² property sold within 1km over the last 180 days, suggesting it offers less space relative to market norms.
- Value Optimization Potential: While the property has 1 bathroom, the median within 1km over 90 days is 2 bathrooms; a second bathroom could add €10,000-€15,000 in value and significantly improve marketability.
- Hypothesis: The C1 BER rating, while not poor, indicates an opportunity for value-add through energy efficiency upgrades; a strategic investment in insulation and heating could align the property with the local market's increasing demand for energy-conscious homes, potentially recouping costs and adding a premium.
Amenities
Excellent Transport Hub: This property is well-connected, situated near the Luas Red Line at The Square Tallaght (approx. 1.5km) and numerous Dublin Bus routes including 27, 54A, 65B, 77A, and 150 serving the wider Tallaght area.
Details
- Comprehensive Local Services: Residents have convenient access to The Square Shopping Centre, with a wide array of retail outlets and supermarkets, as well as nearby healthcare facilities like Tallaght University Hospital (approx. 1.8km).
- Educational and Recreational Access: The property is within proximity to multiple schools, including St. Mary's College, IT Tallaght (now TU Dublin), and Tymon Park, offering significant lifestyle and family appeal.
- Hypothesis: The ongoing development and planned infrastructure upgrades in the Tallaght area, including potential enhancements to public transport links and the expansion of commercial and residential facilities, are likely to increase property values within this specific locality by an estimated 5-8% annually over the next five years, driven by improved connectivity and amenities.
