21 NORMAN AVENUE 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 NORMAN AVENUE sales between September 1999 and November 2012 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 2003 sale was for 87% above the HPI. So the extrapolation line tracks at 87% above the HPI over time, until the November 2012 sale, where it rises to 108% above the HPI. The line then continues to track at 108% above the HPI.

What might 21 NORMAN AVENUE be worth now?

21 NORMAN AVENUE might now be worth an estimated £2,360,089.

This is based on house price inflation of 68.6%, between November 2012 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 68.6% inflationary increase is applied to the most recent sale price for 21 NORMAN AVENUE of £1,400,000 on 19th November 2012. For the value to have increased from £1,400,000 to £2,360,089 over the thirteen years and nine months to February 2025, the following assumptions must hold true:

• The value of 21 NORMAN AVENUE has moved in line with the HPI for semi-detached houses in the Richmond upon Thames local authority area.
