17 RADNOR ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Richmond upon Thames local authority area over time, sourced from the HPI. The two 17 RADNOR ROAD sales from July 1999 and September 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 1999 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the September 2020 sale, where it rises to 3% below the HPI. The line then continues to track at 3% below the HPI.

What might 17 RADNOR ROAD be worth now?

17 RADNOR ROAD might now be worth an estimated £1,656,478.

This is based on house price inflation of 9%, between September 2020 and February 2025, for 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 9% inflationary increase is applied to the most recent sale price for 17 RADNOR ROAD of £1,520,000 on 3rd September 2020. For the value to have increased from £1,520,000 to £1,656,478 over the five years and seven months to February 2025, the following assumptions must hold true:

• The value of 17 RADNOR ROAD has moved in line with the HPI for detached houses in the Richmond upon Thames local authority area.
• The September 2020 sale price of £1,520,000 represented a fair market value for the property.
