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
Significant BER Upgrade Needed: With a G BER rating, upgrading to a B2 standard would likely cost between €15,000-€25,000, but could potentially increase the property's value by €25,000-€35,000 and reduce annual energy costs from an estimated €2,500-€3,500 to €900-€1,300.
Details
- Generous Size: At 150m², the property offers a substantial living space, aligning with the 'Very Large' size category and exceeding the median 3-bedroom property size often found in the 100km radius market.
- Value Optimization Opportunity: While the property is large, its single bathroom and G BER rating represent key areas for immediate investment; retrofitting an additional bathroom could cost €5,000-€10,000 and improve marketability, alongside the essential BER upgrades.
- Hypothesis: The significant discrepancy between the property's asking price and its estimated value, coupled with its poor BER rating, suggests that the current market is not fully valuing energy efficiency and modern amenities, presenting a clear opportunity for a buyer to invest in upgrades and realize substantial capital appreciation.
Amenities
Limited Local Transport: Castlebar is served by Bus Éireann, with routes such as the 440 and 450 connecting to Galway and Westport, but lacks immediate access to train stations or Luas/DART services, requiring significant travel for such options.
Details
- Local Educational Access: The property is within reasonable proximity to primary schools such as Holy Family National School and secondary schools like St. Gerald's College in Castlebar, catering to family needs.
- Community Services: Castlebar offers essential retail services including supermarkets like Tesco and Dunnes Stores, alongside local pharmacies and medical centres, supporting daily living for residents.
- Hypothesis: While Castlebar provides a good base of local amenities and schools, its 'Outside Dublin' location and lack of direct high-speed public transport links mean that properties here may appeal more to local buyers or those seeking a quieter lifestyle, with a lower premium attached to transport convenience compared to commuter towns around Dublin.
