12 KNOWLE ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Richmond upon Thames local authority area over time, sourced from the HPI. The three 12 KNOWLE ROAD sales between May 1995 and March 2017 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 October 2005 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the March 2017 sale, where it falls to 14% below the HPI. The line then continues to track at 14% below the HPI.

What might 12 KNOWLE ROAD be worth now?

12 KNOWLE ROAD might now be worth an estimated £980,227.

This is based on house price inflation of 18.6%, between March 2017 and February 2025, for semi-detached houses, in the Richmond upon Thames local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 18.6% inflationary increase is applied to the most recent sale price for 12 KNOWLE ROAD of £826,750 on 3rd March 2017. For the value to have increased from £826,750 to £980,227 over the eight years and one month to February 2025, the following assumptions must hold true:

• The March 2017 sale price of £826,750 represented a fair market value for the property.
