How to make Zoopla! estimates more accurate
How can you make Zoopla! estimates more accurate? Simple: give us more details about any UK home – like the number of bedrooms or bathrooms it has, or if it has a garden or patio.
The Zoopla! algorithm has been engineered to work well even when there’s a shortage of facts and figures, to learn and adapt quickly when new information becomes available, and to use that new information to offer increasingly accurate value estimates. So the more information we have, the better it works – the algorithm thrives on rich data.
Adding property data on Zoopla!
While we already have great information about many millions of properties, we also lack data on millions more.
For example, the Registers of Scotland doesn’t record the property type with the transaction records. So Zoopla! may know that the property two doors down from your terraced home just sold, but we don’t know that it’s a carbon copy of your place, because we don’t know that it’s terraced and has the same number of beds and baths. Until users edit the data to tell us that all the other houses on the street are terraced, Zoopla! can’t use the information it does know to the fullest extent possible to value this and all the other properties more accurately.
Filling in all the details on your street won’t affect estimates immediately. But as that information percolates through the system, you can expect to see changes in a few days. Try it out, and see what happens.
So please tell us if all the houses on your street are semi-detached. Tell us your mum’s place has 4 beds; tell us the flat upstairs has 2 baths. Every piece of information users like yourselves provide enhances the accuracy and quality of information for the entire Zoopla! community.
Three Ways To Add Property Data
1) Use our quick Edit feature in either the Home Values or Sold Prices channels
2) Refine an existing estimate for a property
3) Use the Get Estimate feature for properties with no current published estimate
And last but not least, spread the word. If you know people that would benefit from this service, get them to find out what their place is worth and contribute to the model. From small acorns…
