7 MOUNT KEEN Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The three 7 MOUNT KEEN sales between May 2003 and March 2021 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 2006 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the March 2021 sale, where it falls to 18% below the HPI. The line then continues to track at 18% below the HPI.

What might 7 MOUNT KEEN be worth now?

This is based on house price inflation of 12.9%, between March 2021 and February 2025, for detached houses, in the North Hertfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 12.9% inflationary increase is applied to the most recent sale price for 7 MOUNT KEEN of £565,000 on 11th March 2021. For the value to have increased from £565,000 to £637,876 over the four years and one month to February 2025, the following assumptions must hold true:
