12 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 two 12 NORMAN AVENUE sales from September 1995 and June 2002 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 September 1995 sale was for 85% above the HPI. So the extrapolation line tracks at 85% above the HPI over time, until the June 2002 sale, where it falls to 82% above the HPI. The line then continues to track at 82% above the HPI.

What might 12 NORMAN AVENUE be worth now?

The 196.1% inflationary increase is applied to the most recent sale price for 12 NORMAN AVENUE of £697,500 on 21st June 2002. For the value to have increased from £697,500 to £2,065,565 over the 23 years and four months to February 2025, the following assumptions must hold true:
