139 WEST END Price Paid vs. HPI Average

The below graph shows the average detached house price in the Sevenoaks local authority area over time, sourced from the HPI. The three 139 WEST END sales between September 1998 and November 2019 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 2008 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the November 2019 sale, where it rises to 29% below the HPI. The line then continues to track at 29% below the HPI.

What might 139 WEST END be worth now?

139 WEST END might now be worth an estimated £673,227.

This is based on house price inflation of 15.9%, between November 2019 and December 2024, for detached houses, in the Sevenoaks local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 15.9% inflationary increase is applied to the most recent sale price for 139 WEST END of £580,900 on 14th November 2019. For the value to have increased from £580,900 to £673,227 over the four years and eleven months to December 2024, the following assumptions must hold true:

• The value of 139 WEST END has moved in line with the HPI for detached houses in the Sevenoaks local authority area.
• The November 2019 sale price of £580,900 represented a fair market value for the property.
