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 Potential: The D1 BER rating suggests that upgrading to a B2 rating could cost between €8,000-€12,000 and potentially increase the property's value by €15,000-€20,000.
Space Efficiency: With 204m² and 4 bedrooms, the property offers 51m² per bedroom, which is a reasonable size for family living in Dublin.
Value Optimization Opportunity: While the BER is D1, the property's size and configuration offer a solid base; targeted energy efficiency upgrades could unlock significant long-term value and reduce annual energy costs, estimated at €1,800-€2,200, compared to B-rated properties saving €1,000-€1,400 annually.
Hypothesis: The D1 BER rating, while impacting immediate energy costs and potentially market appeal, presents a clear opportunity for a buyer willing to invest in retrofitting to achieve a significantly higher BER, thereby increasing resale value and reducing ongoing expenditure, turning a current cost into a future asset appreciation.

Transport Links: This location is served by Dublin Bus routes 17, 44, and 61, offering connectivity to the city centre and surrounding areas.
