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 Rating Impact: With a C1 BER rating, annual energy costs are estimated to be €1,500-€2,000, compared to €800-€1,200 for an A-rated property of similar size.
Upgrade Potential: Improving the BER from C1 to B2 would likely cost €7,000-€10,000 and could potentially increase property value by €12,000-€18,000.
Space Efficiency: At 120m² with 1 bedroom and 1 bathroom, this apartment offers a very high per-bedroom area of 120m², which is inefficient for typical single-bedroom units and may impact resale appeal compared to more compact layouts.
Hypothesis: The significant disparity between the median sale price of similar broad types (€465,000 within 1km) and the estimated value of this 1-bedroom, 120m² unit (€577,800) suggests that the market may be undervaluing larger, lower-bedroom-count apartments, or that this specific unit has features not captured by basic metrics that justify its price despite the apparent inefficiency.
Amenities
Transport Connectivity: The property is well-served by Dublin Bus routes 46A, 61, and 116, with the Luas Green Line at Sandyford or Stillorgan stops accessible for broader city reach.
Educational Hub: The area boasts excellent educational facilities, including St. Benildus College, Mount Anville Secondary School, and Oatlands College, all within a short distance.
Retail and Leisure: Residents have easy access to Stillorgan Shopping Centre and Dundrum Town Centre for extensive retail, dining, and entertainment options.
Hypothesis: The established reputation of The Grange development, coupled with its proximity to high-performing schools and premium retail centres like Dundrum Town Centre, creates a strong lifestyle appeal that may justify a premium over other properties in the wider Dublin market, even with less ideal internal configurations.
