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 E1 BER rating could cost approximately €8,000-€12,000, potentially increasing the property value by €15,000-€20,000 and significantly lowering annual energy costs from an estimated €1,800-€2,200.
Space Efficiency: With 143.0m² and 4 bedrooms, the property offers 35.75m² per bedroom, which is generally good but could be enhanced with better layout optimization to maximize living space.
Value Optimization: Addressing the E1 BER rating is the primary optimization needed, as improving it to a C or B rating would make the property more attractive and marketable against newer or renovated homes in the area.
Hypothesis: Properties with E1 BER ratings in this area, while commanding high absolute prices, are likely to see disproportionately larger value increases upon energy efficiency upgrades compared to properties already at C or B ratings, making the €8,000-€12,000 investment highly strategic.
Amenities
Transport Links: The area is served by Dublin Bus routes 25A, 25X, 66, and 67, providing good connectivity, with the nearest Luas Red Line stop at Tallaght approximately 3km away.
Local Conveniences: Residents have access to SuperValu Knocklyon (1km), the Eden House (restaurant) (1.2km), and Marlay Park (2km), offering a range of shopping, dining, and recreational options.
Educational Access: The property is within proximity to excellent educational institutions, including St. Colmcille's Community School (1.5km) and Loreto Beaufort (2.5km), popular choices for secondary education.
Hypothesis: The strong presence of established secondary schools and large family-oriented parks like Marlay Park within a 2km radius suggests that properties in this specific micro-location are highly sought after by families, potentially creating a consistent demand that insulates against minor market fluctuations.
