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 this property's D2 BER rating to a B2 could cost €8,000-€12,000, potentially increasing the property's value by €15,000-€20,000 and saving €1,000-€1,400 annually in energy costs compared to D-rated homes.
Details
- Aligned Property Size: The property's 68 square metres is well-aligned with the average property size of 66 square metres for 2-bedroom homes sold within a 1km radius in the last 30 days, ensuring it fits buyer expectations for its bed count.
- Desirable House Type: As an end-of-terrace house, this property belongs to the dominant market segment, with houses making up over 86% of sales within a 1km radius over the past 180 days.
- Hypothesis: The prevalence of older housing stock with lower BER ratings within the 1km radius suggests a growing market for energy-efficient upgrades, positioning properties with improved BERs as significantly more attractive and valuable in the near future.
