Asking price vs comparable homes High confidence
Priced higherAbout rightPriced lower
The asking price sits above our fair-value estimate.
Anchored on 1 recent sale on this street, adjusted to today's prices, alongside comparable homes on the market now — beds, size, BER, type and area. Our estimate for a home like this is around €863,000 (€777,000–€949,000). Estimates at this confidence land within 20% of the sale price about 72% of the time.
This compares the asking price only. It cannot see condition, interior, garden or aspect — a home priced low may need work. Use it to shortlist, not to decide. Our price model is typically within ~18%, so treat the range, not the midpoint, as the signal.

Area context, not a like-for-like guide to this home.
Fair value blends our price model with the price per m² of 24 comparable homes for sale; the asking is 15% above its midpoint. Homes in Ireland often sell over asking in strong areas, so the top of the range is fair value, not a ceiling. A guide for your negotiation, not a valuation — the right bid also depends on how much you want it and what you can borrow.
