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 Potential: Upgrading the D2 BER rating to a B2 could cost an estimated €8,000-€12,000 but may increase the property's value by €15,000-€20,000, representing a strong return on investment.
Current Energy Costs: With a D2 BER rating, annual energy costs are estimated between €1,800-€2,200, significantly higher than the €800-€1,200 for properties with a B2 rating, highlighting a substantial ongoing expense.
Space Efficiency: The property offers 120m² across 4 bedrooms and 3 bathrooms, a configuration that aligns well with family needs but may not be as space-efficient as newer builds with more open-plan living areas, potentially impacting appeal to certain buyer segments.
Hypothesis: The current D2 BER rating implies that the property's insulation and heating systems are likely outdated, and a comprehensive upgrade to a B2 rating would not only add significant market value but also position it competitively against newer constructions with superior energy performance.
Amenities
Transport Connectivity: Knocklyon is served by Dublin Bus routes 15B and 49, providing direct links to Dublin City Centre and surrounding areas, and is approximately a 30-minute bus journey to the nearest Luas Green Line stop at Tallaght.
Educational Hub: The area boasts excellent educational facilities including St. Colmcille's Community School (secondary) and St. Thomas the Apostle National School (primary), both within a 1km radius, catering to family needs.
Local Shopping and Services: Residents have convenient access to the Knocklyon Shopping Centre, which includes a SuperValu supermarket, pharmacies, and various retail outlets, all within a 1.5km walk.
Hypothesis: The ongoing development of a new transport hub in the wider Dublin 16 area, which is expected to integrate bus services with enhanced cycle lanes and potentially a future Metro Link extension, could significantly boost property values in Knocklyon by improving commute times and accessibility within the next 5 years.
