15 THORNHILL AVENUE 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 three 15 THORNHILL AVENUE sales between December 1996 and August 2018 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 November 2011 sale was for 16% below the HPI. So the extrapolation line tracks at 16% below the HPI over time, until the August 2018 sale, where it falls to 22% below the HPI. The line then continues to track at 22% below the HPI.

What might 15 THORNHILL AVENUE be worth now?

15 THORNHILL AVENUE might now be worth an estimated £982,690.

This is based on house price inflation of 13%, between August 2018 and February 2025, 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 13% inflationary increase is applied to the most recent sale price for 15 THORNHILL AVENUE of £870,000 on 30th August 2018. For the value to have increased from £870,000 to £982,690 over the seven years and six months to February 2025, the following assumptions must hold true:

• The value of 15 THORNHILL AVENUE has moved in line with the HPI for detached houses in the Kingston upon Thames local authority area.
• The August 2018 sale price of £870,000 represented a fair market value for the property.
