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
Good Energy Efficiency: The B2 BER rating offers a significant advantage, placing its annual energy costs around €1,200-€1,800, compared to €2,000-€2,800 for a typical D-rated property of similar size.
Details
- Generous Space: At 90sqm, this terrace is 30sqm larger than the average property size within a 3km radius (60sqm), offering better value per square meter and a more comfortable living space.
- Value Enhancement Opportunity: While the B2 rating is good, upgrading to an A-rating would require an estimated €10,000-€15,000 in works but could potentially increase property value by €20,000-€30,000, representing a strong return on investment.
- Hypothesis: Given that properties with 3 bedrooms and 3 bathrooms typically command a higher price per square meter within a 1km radius, this property's configuration is well-aligned with local demand, suggesting its size and layout are key value drivers.
Amenities
Key Transport Links: While specific routes serving Castlelyon Avenue aren't detailed, Newcastle is typically served by Dublin Bus routes such as the 68, 69, and 69X, providing connectivity to Dublin City Centre.
Details
- Local Services Access: Within a short drive, residents have access to shops like SuperValu Newcastle and various local cafes and restaurants, contributing to daily convenience.
- Educational Proximity: Nearby schools include St. Finian's National School and Coláiste Chiaráin secondary school, making it a potentially attractive location for families.
- Hypothesis: The development of the planned IDA Ireland Business Park in the nearby area is likely to increase demand for housing in Newcastle by 5-7% over the next three years, driving up property values due to improved local employment opportunities and commuter convenience.
