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 Value: With a C3 BER rating, this property's annual energy costs are estimated to be €1,500-€1,900, which is approximately €300-€700 higher than for properties with A or B ratings in the area.
Upgrade Potential: Improving the BER rating from C3 to a B2 could cost an estimated €7,000-€10,000 and potentially increase the property's value by €12,000-€18,000, offering a solid return on investment.
Space Efficiency: At 105m², this 4-bedroom, 2-bathroom end-of-terrace house offers a good balance of living space and bedrooms, comparing favorably to the average size of properties sold within 1km which have a median sale price of €376,000.
Hypothesis: The C3 BER rating represents a significant opportunity for value enhancement; investing in insulation and efficient heating systems could not only reduce running costs by €500-€900 annually but also appeal to a wider buyer demographic seeking energy-efficient homes.
Amenities
Transport Links: The property is well-served by Dublin Bus routes including the 25, 66, and 67, providing direct access to Dublin city centre and surrounding areas.
Local Services: Residents have access to essential amenities including The Square Tallaght shopping centre, Tallaght University Hospital, and numerous schools such as St. Mary's National School, all within a short commute.
Recreation Options: The proximity to Tymon Park offers significant green space for recreation and leisure activities, enhancing the quality of life for residents.
Hypothesis: The ongoing development and planned upgrades to public transport infrastructure in Dublin 24, particularly enhancements to Luas services and associated park-and-ride facilities, could lead to increased property values in areas like Alderwood Avenue within the next 3-5 years.
