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 Upgrade Opportunity: Upgrading the C2 BER rating to a B2 could cost an estimated €8,000-€12,000 and is projected to increase the property's value by €15,000-€20,000, offering a solid return on investment.
Size Standard: At 99m², the property aligns with the average property size of 104m² within a 1km radius over the past 180 days, indicating it offers a comparable living space to other comparable units.
Configuration Alignment: The 2-bedroom, 2-bathroom configuration is consistent with the median for the area, with 2 bedrooms being the median in the 1km radius over the last 180 days, meeting typical buyer needs.
Hypothesis: Given the C2 BER rating and the relatively standard size and configuration, the property's current asking price suggests a significant discount, implying that the market may be undervaluing the potential for value enhancement through BER upgrades and minor refurbishments.
Amenities
Connectivity Hub: This location is well-served by Dublin Bus routes 25A, 25B, 25D, 66, 66A, 66B, 67, and 67A, providing excellent access to Dublin city centre and surrounding areas.
Local Services Richness: Residents have convenient access to Ongar Village shopping centre, The Centre Park, and proximity to schools like Castaheeny Educate Together National School and Hartstown Community College.
Commuter Friendly: The proximity to the Ongar Luas Red Line stop (approximately 1.5km walk) offers efficient public transport links into the city centre, reducing reliance on private vehicles.
Hypothesis: The combination of extensive bus routes and proximity to the Luas line, coupled with a growing number of local amenities and family-focused facilities in Ongar, suggests that property values in this specific micro-location are poised for sustained growth as infrastructure and services continue to develop.
