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: The D1 BER rating indicates significant room for improvement; upgrading to a B2 rating could cost an estimated €8,000-€12,000 and is likely to increase the property's value by €15,000-€20,000, making it a sound investment.
Details
- Compact Footprint: At 47m², this property is substantially smaller than the average property size within a 1km radius (149.46m² over 180 days) and within 3km (101.46m² over 90 days), suggesting it may be best suited for singles or couples seeking minimal upkeep.
- Value Optimization Opportunity: Given the D1 BER and compact size, an investment in energy efficiency upgrades and potentially a modest extension, if planning permits, could significantly enhance its market appeal and resale value, capitalizing on the strong local demand for well-appointed homes.
- Hypothesis: The current D1 BER rating on this compact terrace, despite its small size, represents a significant opportunity for value uplift; by strategically investing in insulation and heating system upgrades, the property could achieve a B-rated BER, potentially adding 5-10% to its value and reducing annual energy costs by €800-€1,200 compared to its current rating.
Amenities
Excellent Transport Hub: Located in Clontarf, this property benefits from proximity to Dublin Bus routes 130, 31, and 32, providing direct access to Dublin city centre and surrounding areas, with the Clontarf Road DART station approximately a 15-minute walk away.
Details
- Local Lifestyle Amenities: Residents have easy access to local shops and cafes along Vernon Avenue, with further retail options at the Omni Shopping Centre (approx. 3km). St. Paul's College and Belgrove Senior School are within walking distance, and the Mater Hospital is accessible via public transport.
- Walkable Green Spaces: The property is ideally situated for enjoying the coastline and Clontarf Promenade, perfect for walking and cycling, with the extensive St. Anne's Park offering playgrounds, sports facilities, and walking trails, enhancing quality of life for residents.
- Hypothesis: The combination of excellent DART connectivity, a vibrant local shopping street (Vernon Avenue), and abundant green spaces like St. Anne's Park positions Clontarf as a highly desirable location for families and commuters, which, coupled with ongoing infrastructure improvements in the wider Dublin area, is likely to sustain strong property value growth and demand for properties in this specific square.
