Is the 11 The Green house price rising or falling?
The 11 The Green house price estimate has risen in the past year, increasing by 3% or £29,000.
Can I afford to buy 11 The Green?
What property you can afford will depend on your financial situation and estimates of how much you can afford to borrow for a mortgage. Mortgage lenders use different rules to calculate how much you can borrow and what interest you will pay.
For example, if a mortgage lender allowed you to borrow 4.5x income and you could afford a 30% deposit of £343,800, then your annual income would need to be at least £178,267 to meet 11 The Green's current valuation of £1,146,000.
How is the 11 The Green investment score calculated?
The investment score measures historic short-term and long-term house price trends.
Properties with high long-term and short-term returns will have the highest scores. Equally, properties with negative returns will have a lower score.
Past performance, however, does not guarantee future returns, and price rises may have been due to extensions or other improvements to the property.
How does the size of 11 The Green compare?
The house has 1,690 sq ft of internal floor area, which is 78% larger than the 950-square-foot average UK home.
How is the 11 The Green valuation estimated?
A house or flat valuation is estimated using sold prices and house price trends of similar properties in the area.
Each valuation uses our Repeat Sales House Price Index, which tracks price trends in large areas such as cities or towns. We use the index and local price trends (e.g. price increases in a street or postcode) to estimate property value.
The value estimates are most accurate when a property has sold recently and when there are similar properties nearby.
A valuation can, in some cases, be inaccurate. For example, if there have been significant changes to a property since it was last sold (e.g. an extension).
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 property types/tenures are from 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 2013 property survey.
What 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.
