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
Energy Upgrade Opportunity: Upgrading this D1 BER property to a B2 rating could cost €8,000-€12,000 but potentially increase its market value by €15,000-€20,000, offering a significant return on investment and improved living costs.
Compact Living: At 81m², this 2-bedroom apartment offers a practical living space, which is smaller than the median 3 to 4-bedroom properties (based on 5km radius data over 180 days) found in the broader local market, catering to specific buyer needs for a more manageable footprint.
Value Enhancement: Current annual energy costs for this D1 BER property are estimated at €1,800-€2,200, compared to €800-€1,200 for B-rated properties of this size, highlighting potential annual savings of €1,000-€1,400 with an energy upgrade.
Hypothesis: Given that 100% of BER ratings in sales data within a 50km radius over the past 180 days are recorded as 'unknown', a comprehensive BER upgrade for this D1 rated apartment could offer a far more significant market advantage than in areas with more transparent energy efficiency reporting, making it a standout listing for environmentally conscious buyers.
Amenities
Excellent Connectivity: The property benefits from strong public transport links, with Castlebar Train Station approximately 1km away providing direct rail services to Dublin Westport, and multiple Bus Éireann routes, including the 52 (to Dublin) and 450 (to Westport), accessible within a 5-minute walk from Rock Square.
Vibrant Lifestyle Hub: Situated in Castlebar's heart, residents have immediate access to the Linenhall Arts Centre (50m) and the Royal Theatre (300m), with major supermarkets like Tesco and Dunnes Stores both within a 1.5km radius, catering to diverse shopping and entertainment needs.
Walkable Family Environment: Ideal for families, the property is within a 1km walk of Scoil Raifteirí and St. Angela's National School, with Happy Days Crèche equally close, and excellent pedestrian access to the scenic Castlebar Greenway and Lough Lannagh for outdoor activities.
Hypothesis: The property's prime central location in Castlebar, coupled with the town's ongoing investment in urban green infrastructure like the Castlebar Greenway (500m), will likely create a premium for highly walkable properties with immediate access to lifestyle amenities, distinguishing them from more suburban offerings and potentially leading to above-average appreciation for properties in this specific micro-location.
