Are online house price estimates reliable enough to set an asking price?

Online house price estimates are useful for building a rough range, but they are not usually reliable enough to set an asking price with confidence. They do not assess condition or presentation, and they often struggle with homes that have been extended, modernised, reconfigured or unusually located. A professional valuation is typically more dependable because it uses the most relevant comparables and accounts for what buyers are currently paying, not just what historic averages suggest.
