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 C2 Advantage: The C2 BER rating offers moderate energy efficiency, implying annual energy costs of approximately €1,400-€1,800, which is better than D-rated properties in the area that might incur €1,800-€2,200 annually.
Details
- Compact Efficiency: At 57.0m², this 1-bedroom apartment is smaller than the average property size of 119.4m² within 1km over 180 days, making it a more accessible entry point but potentially limiting future flexibility.
- Value Optimization: Given the strong local market and underscoring the price gap, investing in a BER upgrade from C2 to B2 could cost €8,000-€12,000 and potentially increase property value by €15,000-€20,000, offering a good return on investment.
- Hypothesis: The consistent 100% BER unknown percentage across all timeframes and radii suggests a lack of mandatory energy performance disclosure in recent local sales data, which, paradoxically, may create a market where properties with clearly stated, good BER ratings (like this C2) are disproportionately valued by informed buyers seeking clarity and predictable running costs.
Amenities
Transport Hub Access: While specific routes aren't listed, Knocklyon is served by multiple Dublin Bus routes including the 15, 49, and 65, offering direct access to city centre and surrounding suburbs, alongside proximity to the Luas Green Line at Dundrum (via bus transfer).
Details
- Local Conveniences: Residents are within reach of The Square Shopping Centre in Tallaght and local retail parks for shopping, with multiple primary and secondary schools like St. Colmcille's Community School and Sancta Maria College within a short drive, and access to Tallaght University Hospital.
- Recreational Proximity: The property is well-positioned near essential services, with the Edenmore Park for recreation and a range of cafes and restaurants available in the nearby villages of Templeogue and Rathfarnham, fostering a good quality of life.
- Hypothesis: The underdevelopment of public transport directly serving the Garthy Wood complex, coupled with Knocklyon's increasing popularity as a residential area, presents a significant opportunity for enhanced transport infrastructure, such as dedicated shuttle services to nearby Luas stops or more frequent bus routes, which would substantially increase property values and rental appeal.
