9 RADNOR 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 two 9 RADNOR ROAD sales from May 2010 and June 2019 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 May 2010 sale was for 38% above the HPI. So the extrapolation line tracks at 38% above the HPI over time, until the June 2019 sale, where it rises to 61% above the HPI. The line then continues to track at 61% above the HPI.

What might 9 RADNOR ROAD be worth now?

9 RADNOR ROAD might now be worth an estimated £1,831,872.

This is based on house price inflation of 18.2%, between June 2019 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 18.2% inflationary increase is applied to the most recent sale price for 9 RADNOR ROAD of £1,550,000 on 21st June 2019. For the value to have increased from £1,550,000 to £1,831,872 over the six years and four months to February 2025, the following assumptions must hold true:
