17 THE RIDGE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Kingston upon Thames local authority area over time, sourced from the HPI. The two 17 THE RIDGE sales from July 2010 and August 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 July 2010 sale was for 22% above the HPI. So the extrapolation line tracks at 22% above the HPI over time, until the August 2020 sale, where it rises to 74% above the HPI. The line then continues to track at 74% above the HPI.

What might 17 THE RIDGE be worth now?

17 THE RIDGE might now be worth an estimated £1,358,010.

This is based on house price inflation of 13.2%, between August 2020 and February 2025, for semi-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 13.2% inflationary increase is applied to the most recent sale price for 17 THE RIDGE of £1,200,000 on 21st August 2020. For the value to have increased from £1,200,000 to £1,358,010 over the five years and six months to February 2025, the following assumptions must hold true:

• The value of 17 THE RIDGE has moved in line with the HPI for semi-detached houses in the Kingston upon Thames local authority area.
• The August 2020 sale price of £1,200,000 represented a fair market value for the property.
