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 Impact: A C3 BER rating suggests moderate energy efficiency. Upgrading to a B2 rating would likely cost between €8,000 - €12,000 and could increase the property's value by €15,000 - €20,000, while annual savings could reach €800-€1,400 compared to a D-rated property.
Details
- Generous Size for Area: With a size of 127m², this property offers a substantial living space, which is larger than the median 3-bedroom properties typically seen in broader market data for this region, providing good value in terms of square footage.
- Potential for Value Optimization: While the property is well-sized, the C3 BER rating presents an opportunity for value enhancement through energy efficiency upgrades, potentially increasing its attractiveness and future saleability.
- Hypothesis: Investing in a BER upgrade from C3 to B2 for approximately €10,000 could unlock a 10-15% premium on its current market value by aligning it with higher energy-efficient standards that are becoming increasingly important to buyers.
Amenities
Limited Direct Public Transport: Castlebar does not have Luas or DART services; the nearest train station is Castlebar Railway Station, and bus services would likely involve local routes which are not explicitly detailed here, suggesting potential reliance on private transport for wider connectivity.
Details
- Local Facilities Availability: Castlebar offers essential amenities including supermarkets, schools such as St. Gerald's College, and healthcare facilities like Mayo University Hospital, contributing to a functional local lifestyle.
- Walkability to Services: While specific walking routes are not detailed, the property's location on Pontoon Road suggests proximity to some local shops and potentially parks within Castlebar, offering a reasonable level of local convenience.
- Hypothesis: The development of improved direct bus services connecting Castlebar to major regional hubs, or enhanced infrastructure around Castlebar Railway Station, could significantly boost property values in the area by improving commuter accessibility and reducing reliance on private vehicles.
