23 GREAT SLADES Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Hertsmere local authority area over time, sourced from the HPI. The two 23 GREAT SLADES sales from March 2000 and September 2006 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 March 2000 sale was for 52% above the HPI. So the extrapolation line tracks at 52% above the HPI over time, until the September 2006 sale, where it falls to 7% above the HPI. The line then continues to track at 7% above the HPI.

What might 23 GREAT SLADES be worth now?

23 GREAT SLADES might now be worth an estimated £646,951.

This is based on house price inflation of 112.1%, between September 2006 and February 2025, for semi-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 112.1% inflationary increase is applied to the most recent sale price for 23 GREAT SLADES of £305,000 on 12th September 2006. For the value to have increased from £305,000 to £646,951 over the nineteen years and seven months to February 2025, the following assumptions must hold true:
