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 Rating Impact: With a SI_666 BER rating, upgrading to a B2 rating could cost €8,000-€12,000 and potentially increase the property's value by €15,000-€20,000, representing a sound investment.
Energy Cost Differential: Current annual energy costs for a property with a SI_666 BER rating are estimated to be €1,800-€2,200, significantly higher than the €800-€1,200 for a B-rated property of similar size.
Size vs. Local Norm: At 120.0m², this 1-bedroom cottage is substantial, but the surrounding market with a 1km median sale price of €120,000 for 34 sales suggests the typical sale might involve properties with more bedrooms or a different configuration.
Hypothesis: The derelict nature of the cottage combined with its significant size for a 1-bedroom property indicates a potential for substantial renovation and extension, making it attractive to developers or buyers looking to customize, but the current BER rating presents a significant hurdle that would need to be addressed to unlock full market potential.
Amenities
Transport Connectivity: There are no specific bus routes, train stations, Luas stops, or DART stations mentioned as serving Carroweena, Killasser, Co. Mayo, indicating potentially limited public transport options.
Healthcare Access: Without specific references to hospitals, clinics, or pharmacies in the immediate vicinity of Carroweena, Killasser, healthcare access requires further investigation for this rural location.
Shopping and Retail: The absence of specific shop or supermarket names near Carroweena, Killasser suggests that residents likely rely on nearby towns for retail needs, impacting daily convenience.
Hypothesis: The lack of specific public transport, educational, healthcare, and retail amenities mentioned for Carroweena, Killasser strongly suggests it is a rural area where residents would be highly dependent on private transport to access essential services, meaning that the appeal of this property will be significantly limited to those seeking a very remote lifestyle or who have established local connections.
