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 C1 Impact: A C1 BER rating typically incurs annual energy costs of approximately €1,500-€1,900 for a property of this size, compared to €800-€1,200 for a B-rated property.
Size and Configuration Advantage: With 133m² and 4 bedrooms/4 bathrooms, this bungalow offers a generous living space that is well-configured for larger families, exceeding the typical offering in many urban markets.
Potential for Value Optimisation: While the BER is C1, strategic upgrades to improve energy efficiency, potentially costing €9,000-€14,000 to reach a B2 rating, could add €12,000-€18,000 in property value and reduce annual energy costs by an estimated €500-€700.
Hypothesis: The bungalow configuration, while popular for accessibility, may be undervalued by the market compared to similarly sized houses with more conventional layouts, suggesting that a renovation focusing on modernising living spaces and enhancing the C1 BER rating could unlock significant uplift beyond direct upgrade costs.
Amenities
Excellent Transport Links: Maynooth is served by train services from Maynooth Train Station offering direct access to Dublin city centre, and is well-connected by Dublin Bus routes 25, 25A, 25B, 66, 66A, 66B, 66E, 66N, 67, 67A, 67N, and 67X, providing comprehensive connectivity.
Educational Hub: The area boasts strong educational facilities including Maynooth University, primary schools like St. Mary's Boys' National School and Gaelscoil Uí Dhónaill, and secondary schools such as Maynooth Community Secondary School.
Comprehensive Local Services: Residents benefit from amenities like the Carton House Golf Club, local shops and supermarkets in Maynooth town centre, and access to healthcare facilities including the Maynooth Medical Centre.
Hypothesis: The sustained demand for properties in Maynooth, driven by its robust infrastructure, high-quality educational institutions, and developing lifestyle amenities, suggests that continued investment in public transport and local services will further enhance its appeal, potentially driving property values upwards by 5-8% annually even in a stable market.
