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 Efficiency: The C2 BER rating means the property's annual energy costs are estimated to be €1,400-€1,800, compared to €800-€1,200 for A-rated properties of similar size, representing a potential annual saving of €600-€1,000 by upgrading.
Details
- Size Advantage: At 118m², this 3-bedroom, 3-bathroom semi-detached property is well-sized and aligns with demand for family homes, particularly given the median sale price for same broad type properties within 1km over 180 days was €567,500.
- Value Optimization: Improving the C2 BER rating to a B2 could cost approximately €9,000-€13,000 but is likely to increase the property's value by €18,000-€23,000, offering a strong return on investment.
- Hypothesis: The presence of 3 bathrooms for 3 bedrooms, while a positive feature, could indicate a design focus on convenience over maximizing living space; future buyers might prioritize larger reception areas over an additional bathroom, a trend potentially reflected in the slightly lower sale price compared to similar-sized homes with fewer bathrooms within 1km.
Amenities
Connectivity Hub: This area is served by Dublin Bus routes 25, 66, and 67, offering direct links to Dublin city centre, and is within reasonable proximity to the M50 motorway for wider accessibility.
Details
- Educational Cluster: Close proximity to well-regarded schools such as St. Patrick's National School and Castleknock Community College, along with local childcare facilities, enhances family appeal.
- Local Retail & Green Space: Residents have convenient access to retail options at Carpenterstown Shopping Centre and the Blanchardstown Centre, complemented by nearby recreational areas like Farmleigh Estate and the Phoenix Park.
- Hypothesis: The ongoing development and upgrades to public transport infrastructure in Dublin 15, including potential future enhancements to bus services or extensions of existing light rail networks, could significantly boost property values in areas like Riverwood Gardens by further reducing commuter times and increasing overall accessibility.
