What condition is the property in?

At a sale price of £633,000, the property’s cost per square foot suggests it may be more modest in condition or features compared to neighbouring homes.

Making home improvements could increase the cost per square foot to within the £511 to £616 per square foot range we typically see for detached houses in The Jinnings, 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 2009 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 sold property prices or property types are incorrect, you should verify them with HM Land Registry. You can notify HM Land Registry of any errors.

If any other property details are incorrect or out-of-date, they will update automatically when next surveyed.

You can verify property details related to energy efficiency.
