How do you calculate Zoopla house price estimates?

Zoopla house price estimates on our website are calculated by a proprietary Automated Valuation Model (AVM) powered by Hometrack, the UK's largest automated valuer of residential properties. Hometrack's data is relied upon by 85% of UK mortgage lenders today, 

We get our data from publicly available data including the HM Land Registry Registers of Scotland. Our model looks at the relationships between transaction prices, market values and property characteristics (type, style, tenure, number of bedrooms, etc.); and it uses these patterns and trends to estimate present house prices. 

To be more precise, our Automation Valuation Model considers:

  • previous sold prices for the specific property and recent transactions nearby
  • changes in the market values to similar properties of that type in the local area
  • the various characteristics of the property in question and those around it
  • current asking prices for specific properties and others in the local area
  • the size of the property in question relative to those around it
  • the current values of comparable properties
  • local area and address level data
