12B SOUTHBOROUGH ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Kingston upon Thames local authority area over time, sourced from the HPI. The two 12B SOUTHBOROUGH ROAD sales from June 2017 and February 2020 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 June 2017 sale was for 16% below the HPI. So the extrapolation line tracks at 16% below the HPI over time, until the February 2020 sale, where it rises to 78% above the HPI. The line then continues to track at 78% above the HPI.

What might 12B SOUTHBOROUGH ROAD be worth now?

12B SOUTHBOROUGH ROAD might now be worth an estimated £2,117,110.

This is based on house price inflation of 10.6%, between February 2020 and December 2024, for detached houses, in the Kingston upon Thames local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 10.6% inflationary increase is applied to the most recent sale price for 12B SOUTHBOROUGH ROAD of £1,915,000 on 13th February 2020. For the value to have increased from £1,915,000 to £2,117,110 over the three years and two months to December 2024, the following assumptions must hold true:

• The value of 12B SOUTHBOROUGH ROAD has moved in line with the HPI for detached houses in the Kingston upon Thames local authority area.
• The February 2020 sale price of £1,915,000 represented a fair market value for the property.
