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
Good BER Rating: The B3 BER rating is solid, placing it within the upper half of energy efficiency. Upgrading from B3 to A2 would likely cost €5,000-€8,000 but could potentially reduce annual energy bills by €400-€600 compared to D-rated properties.
Details
- Generous Size: At 126m², this apartment is 72% larger than the average property size of 73m² sold within 1km over the past 180 days, offering substantial living space.
- Value Optimization Opportunity: While the BER is B3, the current asking price of €575,000 for a 126m² 3-bed, 3-bath apartment is approximately €4,563 per square meter, which is lower than the 1km median of €6,941 per square meter, indicating potential for value uplift through targeted upgrades.
- Hypothesis: The B3 BER rating, while good, represents a missed opportunity for significant capital appreciation and operational savings, as properties with A-rated BERs in similar Dublin 18 locations have seen an average of 7-10% higher sale prices due to perceived long-term value and lower running costs.
Amenities
Excellent Transport Hub: Proximity to the QBC on the N11 provides access to numerous Dublin Bus routes including the 46A, 75, and 185, offering direct links to Dublin city center and surrounding areas, with the nearest Luas stop at Sandyford within a 10-minute drive.
Details
- Prime Educational Locale: The area is well-served by reputable schools, including St. Laurence's Boys National School (500m), Loreto High School (1km), and Clonkeen College (1.2km), with UCD accessible via a short bus journey.
- Abundant Lifestyle Choices: Residents have easy access to Cabinteely Village for cafes and local shops, while larger retail needs are met at Cornelscourt Shopping Centre (1.5km) and Dundrum Town Centre (4km), complemented by nearby parks like Kilbogget Park and Cabinteely Park for recreation.
- Hypothesis: The established family-friendly nature of Cabinteely, underscored by its excellent school catchment and proximity to essential amenities, suggests that properties with ample living space like this 3-bed apartment will continue to command strong demand and appreciation, particularly as infrastructure improvements in the wider Dublin area enhance connectivity.
