The below graph shows the average detached house price in the Hertsmere local authority area over time, sourced from the HPI. The two 21 THE CLOSE sales from May 1996 and December 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 May 1996 sale was for 48% below the HPI. So the extrapolation line tracks at 48% below the HPI over time, until the December 1999 sale, where it rises to 43% below the HPI. The line then continues to track at 43% below the HPI.
21 THE CLOSE might now be worth an estimated £669,492.
This is based on house price inflation of 273%, between December 1999 and February 2025, for detached houses, in the Hertsmere local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 273% inflationary increase is applied to the most recent sale price for 21 THE CLOSE of £179,500 on 20th December 1999. For the value to have increased from £179,500 to £669,492 over the 26 years and ten months to February 2025, the following assumptions must hold true:
