18 TWINOAKS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Elmbridge local authority area over time, sourced from the HPI. The four 18 TWINOAKS sales between April 2005 and February 2024 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the February 2015 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the February 2024 sale, where it rises to 7% above the HPI. The line then continues to track at 7% above the HPI.

What might 18 TWINOAKS be worth now?

18 TWINOAKS might now be worth an estimated £1,564,894.

This is based on house price deflation of 2.5%, between February 2024 and December 2024, for detached houses, in the Elmbridge local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.5% deflationary decrease is applied to the most recent sale price for 18 TWINOAKS of £1,605,000 on 22nd February 2024. For the value to have decreased from £1,605,000 to £1,564,894 over the two months to December 2024, the following assumptions must hold true:

• The value of 18 TWINOAKS has moved in line with the HPI for detached houses in the Elmbridge local authority area.
• The February 2024 sale price of £1,605,000 represented a fair market value for the property.
• The size, condition, and specification of 18 TWINOAKS has not materially changed since February 2024.
