Using local prices per square foot as benchmarks for valuation
When valuing this property, one factor we consider is the average cost per square foot (CPSF) for detached houses in the area. Based on this metric alone, the property's valuation would be £650,000.
Our valuation is at the higher end of the £496 to £624 CPSF you would have to pay for a typical detached house in The Green. Factors such as features and outdoor space affect CPSF, with past sale prices reflecting these differences.

What condition is the property in?
At a sale price of £661,000, the property’s cost per square foot indicates a better condition than the neighbouring properties or that it possesses additional features to warrant the higher price.
Making home improvements could increase the cost per square foot within the £496 to £624 per square foot range we typically see for detached houses in The Green, increasing the property's value.
How is the property valuation estimated?
Every month, our Automated Valuation Model (AVM) determines property values.
Our AVM collects data from reputable sources, like HM Land Registry, and uses the data to estimate what each property is worth.
In our tests, we have found that the sale price of a property falls within our AVM's confidence range in most cases. However, there are scenarios where the valuations are not accurate. For example, if significant alterations have been made to a property recently or if a property is unique with few comparables.
For more details on the workings of our AVM, including its strengths, limitations, and how it measures up to traditional valuation methods, please refer to our guide 'How We Value Property'.
We try to make the valuations as accurate as possible, but they are estimates. When buying or selling property, you should speak to a qualified professional.
Where are the figures sourced?
Sold house prices, and data on property types/tenures, are sourced from the HM Land Registry.
There is a time delay in property sales appearing in HM Land Registry, which can be up to three months.
Other property details, such as energy efficiency, are estimates from a 2019 property survey.
What should I do if the details are incorrect?
We generate all our property valuations programmatically. They cannot be manually edited based on new information, such as evidence of redevelopment.
If any other property details are incorrect or out-of-date, they will update automatically when next surveyed.
