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
Energy efficiency savings: With a C2 BER rating, this apartment offers good energy efficiency, with estimated annual energy costs of €1,200-€1,600, potentially saving owners €600-€1,000 annually compared to a D-rated property of similar size (estimated €1,800-€2,200).
Details
- Optimal configuration: At 90m² with 3 bedrooms and 2 bathrooms, the property offers a practical and spacious layout for an apartment, aligning perfectly with the median 3-bed, 2-bath configuration observed in sales within the 1km radius.
- Strong market positioning: The C2 BER rating provides a distinct advantage in a local market where 100% of the past 180 days' sales data has an unknown BER, bypassing the need for costly upgrades (estimated €8,000-€12,000 for a D to B2 uplift) faced by many older properties.
- Hypothesis: As buyer preferences increasingly lean towards energy-efficient homes, the property's C2 BER provides a strong foundational appeal, suggesting that even minor, cost-effective improvements (e.g., smart thermostats or enhanced insulation) could yield disproportionate value increases and attract premium buyers in the current market.
Amenities
Exceptional transport access: The property benefits from excellent connectivity via the Luas Green Line (Stillorgan and Sandyford stops, approx. 15-20 min walk/short bus ride), providing direct links to Dublin City Centre, complemented by frequent Dublin Bus routes (e.g., 11, 46A, 75, 116, 145) along the N11 corridor.
Details
- Comprehensive local facilities: Stillorgan offers a wealth of amenities, including Stillorgan Village Shopping Centre (featuring SuperValu, Dunnes Stores) for daily needs, Dundrum Town Centre for extensive retail, and educational institutions like Oatlands Primary School and University College Dublin (UCD) nearby.
- Vibrant lifestyle & healthcare: Residents can enjoy lifestyle amenities such as Leisureplex Stillorgan, various local cafes and restaurants in Stillorgan village, and green spaces like Clonmore Park, with convenient healthcare access through local GP clinics and pharmacies, and St. Vincent's University Hospital a short drive away.
- Hypothesis: The strategic location near the expanding Sandyford Business District, combined with an already robust transport infrastructure and a full suite of amenities, suggests a sustained appeal for professionals and families, driving both rental and sale demand for well-located properties like this apartment.
