23 COPTHALL GARDENS Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Richmond upon Thames local authority area over time, sourced from the HPI. The two 23 COPTHALL GARDENS sales from December 1999 and May 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 December 1999 sale was for 45% above the HPI. So the extrapolation line tracks at 45% above the HPI over time, until the May 2024 sale, where it rises to 61% above the HPI. The line then continues to track at 61% above the HPI.

What might 23 COPTHALL GARDENS be worth now?

This is based on house price inflation of 9.1%, between May 2024 and June 2025, for terraced 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 9.1% inflationary increase is applied to the most recent sale price for 23 COPTHALL GARDENS of £1,380,000 on 3rd May 2024. For the value to have increased from £1,380,000 to £1,505,188 over the eleven months to June 2025, the following assumptions must hold true:
