The below graph shows the average detached house price in the South Norfolk local authority area over time, sourced from the HPI. The two 121 THE STREET sales from October 1996 and May 1999 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 1996 sale was for 84% above the HPI. So the extrapolation line tracks at 84% above the HPI over time, until the May 1999 sale, where it falls to 79% above the HPI. The line then continues to track at 79% above the HPI.
121 THE STREET might now be worth an estimated £789,071.
This is based on house price inflation of 369.7%, between May 1999 and February 2025, for detached houses, in the South Norfolk local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 369.7% inflationary increase is applied to the most recent sale price for 121 THE STREET of £168,000 on 5th May 1999. For the value to have increased from £168,000 to £789,071 over the 26 years and three months to February 2025, the following assumptions must hold true:
