21 SANDYCOOMBE 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 21 SANDYCOOMBE ROAD sales between August 1999 and October 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 June 2005 sale was for 80% above the HPI. So the extrapolation line tracks at 80% above the HPI over time, until the October 2017 sale, where it falls to 78% above the HPI. The line then continues to track at 78% above the HPI.

What might 21 SANDYCOOMBE ROAD be worth now?

21 SANDYCOOMBE ROAD might now be worth an estimated £2,026,574.

This is based on house price inflation of 16.5%, between October 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 16.5% inflationary increase is applied to the most recent sale price for 21 SANDYCOOMBE ROAD of £1,740,000 on 20th October 2017. For the value to have increased from £1,740,000 to £2,026,574 over the eight years and eight months to February 2025, the following assumptions must hold true:

• The value of 21 SANDYCOOMBE ROAD has moved in line with the HPI for semi-detached houses in the Richmond upon Thames local authority area.
• The October 2017 sale price of £1,740,000 represented a fair market value for the property.
