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 C3 Energy Efficiency: This C3 BER rating suggests moderate energy efficiency, with estimated annual energy costs likely to be €1,400-€1,800, compared to the €800-€1,200 for an A-rated property of similar size.
Potential for Value Uplift: Improving the BER from C3 to a B2 rating could cost approximately €7,000-€10,000 and potentially add €10,000-€15,000 to the property's market value.
Generous Space: With 120m², this property offers ample living space for a 4-bedroom, 2-bathroom semi-detached home, aligning well with family needs and offering good space efficiency compared to potentially smaller properties in denser areas.
Hypothesis: Given the C3 BER rating, there's a significant opportunity to enhance value and reduce long-term running costs through targeted energy upgrades; focusing on insulation and heating systems could bridge the gap between its current energy performance and the higher standards seen in newer or recently renovated properties within the local market.
Amenities
Connectivity via N5: Situated on Westport Road, the property benefits from direct access to the N5, a primary national route connecting to the wider road network, facilitating travel to Westport (30 minutes) and further afield.
Local Schools Access: The area is served by primary and secondary schools such as St. Patrick's Boys National School and St. Nathy's College, both located within a short drive, offering convenient educational options for families.
Proximity to Castlebar Town Centre: Castlebar town centre, with its supermarkets (Tesco, Aldi), retail units, and restaurants (e.g., Davitt Restaurant), is approximately 2km away, providing easy access to essential services and leisure activities.
Hypothesis: While Castlebar itself is well-served by local amenities and road infrastructure, the lack of direct public transport links like bus routes (e.g., Bus Éireann services would require travel to the town centre) or train stations within immediate walking distance might present a slight challenge for non-drivers, potentially impacting its appeal to a broader buyer demographic seeking seamless public transport commutes.
