21 PROWSE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hertsmere local authority area over time, sourced from the HPI. The two 21 PROWSE AVENUE sales from December 2013 and April 2023 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 December 2013 sale was for 104% above the HPI. So the extrapolation line tracks at 104% above the HPI over time, until the April 2023 sale, where it rises to 240% above the HPI. The line then continues to track at 240% above the HPI.

What might 21 PROWSE AVENUE be worth now?

This is based on house price deflation of 6.2%, between April 2023 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 6.2% deflationary decrease is applied to the most recent sale price for 21 PROWSE AVENUE of £4,250,000 on 4th April 2023. For the value to have decreased from £4,250,000 to £3,985,564 over the two years and two months to February 2025, the following assumptions must hold true:

• The value of 21 PROWSE AVENUE has moved in line with the HPI for detached houses in the Hertsmere local authority area.
• The April 2023 sale price of £4,250,000 represented a fair market value for the property.
