19 CHALMERS WAY 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 19 CHALMERS WAY sales from October 2008 and February 2024 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 2008 sale was for 122% above the HPI. So the extrapolation line tracks at 122% above the HPI over time, until the February 2024 sale, where it falls to 2% below the HPI. The line then continues to track at 2% below the HPI.

What might 19 CHALMERS WAY be worth now?

This is based on house price deflation of 0.3%, between February 2024 and December 2024, 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 0.3% deflationary decrease is applied to the most recent sale price for 19 CHALMERS WAY of £1,600,000 on 1st February 2024. For the value to have decreased from £1,600,000 to £1,595,658 over the two months to December 2024, the following assumptions must hold true:

• The February 2024 sale price of £1,600,000 represented a fair market value for the property.
