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 Upgrade Potential: Given a SI_666 BER rating, investing €8,000-€12,000 to upgrade to a B2 rating could increase property value by €15,000-€20,000, representing a positive return on investment.
Details
- Generous Space: At 162m², this detached house offers a very large size category, exceeding the median 3-bedroom configuration prevalent in the wider market, providing ample living space.
- Value Optimization Opportunity: While the size is ample, the property's current estimated value of €298,599 is significantly below its asking price of €415,000, indicating potential for value optimization through renovations or staged selling to better align with market expectations.
- Hypothesis: The SI_666 BER rating suggests that while the property has ample space, its energy performance is a significant drawback; a focused upgrade to a B2 or A3 rating could not only recoup its costs through increased value but also unlock a new buyer demographic actively seeking energy-efficient homes, potentially reducing the time on market by up to 30%.
Amenities
Limited Local Transport: Birr, Co. Offaly, is not directly served by national rail lines or DART/Luas services, and specific local bus route numbers are not provided in the data, indicating limited public transport connectivity.
Details
- Rural Service Access: While specific local shops and healthcare facilities for Riverstown are not detailed, Birr town centre, approximately 5km away, would typically offer essential amenities like supermarkets, pharmacies, and a local hospital (e.g., Midland Regional Hospital, Portlaoise, is ~50km away).
- Family & Lifestyle Amenities: Specific schools, childcare, parks, or restaurants in Riverstown are not detailed in the provided data, suggesting amenities might require travel to the nearest town.
- Hypothesis: The lack of direct public transport links and detailed local amenities in Riverstown points to a property appealing primarily to those seeking a rural lifestyle, where car dependency is high; however, Birr's town amenities are within a short drive, providing a balance for essential services, but limiting appeal for those prioritising urban connectivity and a walkable lifestyle.
