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
Significant BER Upgrade Opportunity: Upgrading from the current C1 BER rating to a B2 rating could cost an estimated €8,000-€12,000 and potentially increase property value by €15,000-€20,000, representing a strong return on investment.
Details
- Generous Size: With 276 sqm of living space, this property is 79% larger than the average property size of 154 sqm sold within a 1km radius over the last 180 days, offering significant space advantage.
- Premium Configuration: The property features 5 bedrooms and 3 bathrooms, which is above the median of 3 bedrooms and 3 bathrooms within a 1km radius, aligning with demand for larger family homes.
- Hypothesis: The C1 BER rating, while not poor, represents a key opportunity for value enhancement; focusing on targeted insulation and efficient heating system upgrades could not only bolster the BER to B1 or A3, but also reduce annual energy costs by an estimated €1,000-€1,500 compared to its current rating, further increasing its attractiveness in a market where energy efficiency is increasingly valued.
Amenities
Excellent Transport Links: While specific routes aren't provided, Castleknock is well-served by Dublin Bus, and proximity to the M50 motorway offers excellent connectivity to Dublin City Centre and beyond.
Details
- Local Educational Hub: The area is home to esteemed educational institutions such as Castleknock College (secondary), Mount Sackville School (secondary), and St. Brigid's National School (primary), along with several nearby childcare facilities.
- Abundant Local Services: Residents benefit from a wide array of amenities including the Blanchardstown Shopping Centre for retail, Connolly Hospital for healthcare, and numerous local restaurants, cafes, and sports clubs like Castleknock Golf Club.
- Hypothesis: The established amenities in Castleknock, particularly its strong educational and healthcare infrastructure combined with green spaces like Phoenix Park, contribute to a high quality of life that commands a premium, suggesting that continued investment in local public transport enhancements and community facilities will further solidify its position as a sought-after residential location.
